Hi our team is looking into feasibilities of appending customized data to personalized installer, so that we can make new users onboarding experience better. I did some investigations. Append token data to xattr to a dmg, I went though this smoothly. I can successfully retrieve the data back, and the app can still be launched successfully. Want to make sure this doesn't require the dmg to be re-signed and re-notarized, and I didn't miss any steps in between I created a fake simulation app try to sign and notarize. Signing the dmg seems to be successful, but when I notarize, it gave me back Invalid status. Is there anything wrong? This is the signature: Executable=/Users/myname/myname/poc/MySimulation.dmg Identifier=MySimulation Format=disk image CodeDirectory v=20200 size=304 flags=0x0(none) hashes=1+6 location=embedded Hash type=sha256 size=32 CandidateCDHash sha256=e2a149614f6e0e3939db3a 4c762adda0e8c24 CandidateCDHashFull sha256=e2a149614f6e0e3939db3a3054adda0e8c24f597ddf4c4503cd27fb83821 Hash choices=sha256 CMSDigest=e2a149614f6e0e3939dba3054c62adda0e8c24f597ddf4c4503cd27fb83821 CMSDigestType=2 CDHash=e2a149614f6e0e39393a3054c762adda0e8c24 Signature size=4789 Authority=Apple Development: myId (someId) Authority=Apple Worldwide Developer Relations Certification Authority Authority=Apple Root CA Signed Time=Oct 14, 2024 at 3:46:08 PM Info.plist=not bound TeamIdentifier=W3TC3HXUZC Sealed Resources=none Internal requirements count=1 size=188 Do you have any other recommendations for us to append some data that doesn't break signing / notarization?

When I try to launch my own Java app, I get the following error message. xpcproxy exited due to OS_REASON_CODESIGNING | Launch Constraint Violation, error info: c[5]p[1]m[1]e[0], (Constraint not matched) launch type 3, failure proc [vc: 1]: /bin/bash As far as I know, the failing process path is /bin/bash. This issue is only happening on macOS Sequoia. The Java app works without any issue on MacOS Sonoma or any previous macOS versions. I did not make any changes, including launch constraints or any other settings. After updating to macOS Sequoia, I started getting this error and can no longer launch my app. Thank you so much.

Hello, We are using automatic signing for a couple of projects, and we're struggling to get it to work in a CI with Xcode 16. It was working with Xcode 15 but with Xcode 16 we get the following errors : error: The operation couldn’t be completed. Unable to log in with account ''. The login details for account '' were rejected. error: Provisioning profile "iOS Team Provisioning Profile: com.bundleid.my" doesn't include signing certificate "Apple Development: Foobar (TEAMID)". Any ideas ?

I would like to share my new project on an open source repository like GitHub. it need capabilities like iCloud. The problem is that I would prefer not have my appleid email being send to the open source repository. I saw that I can exclude files but I would be easier if the open source version had no Apple account associated with it. how should I manage the open source version vs the App Store one. Thank you

There does not seem to be a way to code sign a PAM module so that an XPC service can verify the signature with setCodeSigningRequirement. There should be a way to build a PAM module (dynamic Library ) so it can be code signed. Put in a bundle and code signing the bundle does not work .

Hi, the documentation says that an application bundle for Mac OS X can have a Frameworks folder within Contents. Using a framework for console applications (no bundle) and GUI applications (bundle), I cannot load the console applications anymore on Ventura. Prior to Ventora I have tested and ran both on Mojave or earlier - I am not sure. To fix the issue, I have moved the frameworks within the application bundle to match the rpath for /Users/lothar/Library/Frameworks when I place the console into /Users/lothar/bin, the same rpath for application bundles works for those within the bin folder. Can I publish an application bundle with that modified layout or do I have to expect getting problems and do rather a Symlink pointing from /Users/lothar/Frameworks to /Users/lothar/Library/Frameworks? Thanks, Lothar

Share and Enjoy — Quinn “The Eskimo!” @ Developer Technical Support @ Apple let myEmail = "eskimo" + "1" + "@" + "apple.com" Resolving Gatekeeper Problems Gatekeeper strives to ensure that only trusted software runs on a user’s Mac. It’s important that your code pass Gatekeeper. If not, you’re likely to lose a lot of customers, and your users’ hard-won trust. There are four common Gatekeeper problems: App blocked by a dangling load command path Broken code signature Lack of notarisation Command-line tool blocked by Gatekeeper The first problem is by far the most common. For the details, see Resolving Gatekeeper Problems Caused by Dangling Load Command Paths. For general information about Gatekeeper, read Apple > Developer > Signing Mac Software with Developer ID and Apple > Support > Safely open apps on your Mac. IMPORTANT This post focuses on Developer ID-signed code. Gatekeeper should not block App Store apps. If an app downloaded from the App Store fails to run, it’s likely to be some other trusted execution issue. For more about this, read Resolving Trusted Execution Problems. macOS 14 introduced gktool, a very minimal interface to Gatekeeper. Run the tool with the help argument to learn more: % gktool help Verify Your Signature A good first step in any Gatekeeper investigation is to verify that your code is signed correctly. Use the codesign tool for this: % codesign -v -vvv --strict --deep MyApp.app The -vvv options increase verbosity to the point where codesign will give you useful diagnostics. For example: % codesign -v -vvv --strict --deep "Munged.app" Munged.app: a sealed resource is missing or invalid file added: …/Munged.app/Contents/Resources/names/Adam.txt file modified: …/Munged.app/Contents/Resources/names/Morgan.txt file missing: …/Munged.app/Contents/Resources/names/Rhonda.txt This app was changed after it was signed in three different ways: Adam.txt was added. Morgan.txt was modified. Rhonda.txt was removed. You might see some results that make no sense. For example: Start with an app with a valid code signature: % codesign -v -vvv --strict --deep "NotNormal.app" NotNormal.app: valid on disk NotNormal.app: satisfies its Designated Requirement Use the Finder to create a zip archive (File > Compress). Use the Finder to unpack that archive. Check the code signature of the unpacked file: % codesign -v -vvv --strict --deep "NotNormal 2.app" NotNormal 2.app: a sealed resource is missing or invalid file added: …/NotNormal 2.app/Contents/Resources/names/Zoë Schrödinger.txt file missing: …/NotNormal 2.app/Contents/Resources/names/Zoë Schrödinger.txt There are two things to note here. First, just compressing and decompressing the app broke its code signature. Weird! Second, look at the error messages. It seems that the Zoë Schrödinger.txt file is was both added and removed. Weirder! To see what’s going on here you have to look at a hex dump of the file name: % ls "NotNormal.app/Contents/Resources/names" | xxd 00000000: 5a6f c3ab 2053 6368 726f cc88 6469 6e67 Zo.. Schro..ding 00000010: 6572 2e74 7874 0a er.txt. % ls "NotNormal 2.app/Contents/Resources/names" | xxd 00000000: 5a6f 65cc 8820 5363 6872 6fcc 8864 696e Zoe.. Schro..din 00000010: 6765 722e 7478 740a ger.txt. The names are not the same! The app started out with the ë in precomposed form and the ö in decomposed form. Compressing and decompressing the app converted the ë to its decomposed form, and that change broke the code signature. Programs that deal with Unicode are expected to ignore differences in normalisation. Sadly, Apple’s code signing implementation missed that memo (r. 68829319). For more details see this post but the executive summary is that it’s best to stick to ASCII when naming files in a bundle. Identify a Notarisation Problem Gatekeeper requires that your app be notarised. If not, it will block the execution of your app with a generic, user-level message. If you find your app blocked by Gatekeeper, check if this is a notarisation issue by looking in the system log for an entry like this: type: info time: 2022-05-11 14:57:21.812176 -0700 process: syspolicyd subsystem: com.apple.syspolicy category: default message: ticket not available: 2/2/8b7410713591e6c79ea98f0132136f0faa55d22a Note If the ticket details show as <private>, enable private data in the system log. For information on how to do that, see Recording Private Data in the System Log. For general information about the system log, see Your Friend the System Log. The long hex number is the code directory hash, or cdhash, of the offending code. In this example, it’s the cdhash of the app itself: % codesign -d -vvv /Applications/NotNotarised.app … CDHash=8b7410713591e6c79ea98f0132136f0faa55d22a … However, in some cases it may be the cdhash of some library referenced by the app. For more information about cdhashes, see TN3126 Inside Code Signing: Hashes. Resolve a Notarisation Problem The obvious cause of this problem is that you haven’t notarised your app. For information on how to do that, see Notarizing macOS Software Before Distribution. If you have notarised your app and yet you still see this problem, something more subtle is happening. For example, your app might reference a dynamic library that wasn’t seen by the notary service. To investigate this: Fetch the notary log for your app. For advice on that, see Fetching the Notary Log. Confirm that the notary log matches the app you installed. Look in the notary log for the sha256 property. Its value is a SHA-256 hash of the file received by the notary service. Check that this matches the SHA-256 hash of the file you used to install your app. If not, see Hash Mismatch, below. Search the notary log for the cdhash value from the Gatekeeper log message. If the notary log doesn’t contain that cdhash, that code wasn’t included in the notarised ticket. It’s possible that you failed to submit the code to the notary service, that it was switched out with a different version after you notarised your app, that it was package in some way that the notary service couldn’t see it, or that something went wrong within the notary service. Hash Mismatch If you stapled your notarised ticket to the file used to install your app then the hashes in step 2 of the previous section won’t match. What to do depends on the file type: If the file used to install your app was a zip archive (.zip), you definitely have the wrong file. Zip archives don’t support stapling. If the file used to install your app was a signed disk image (.dmg), compare the disk image’s cdhash with the cdhash for the disk image in the notary log. If those match, you know you’re working with the same disk image. To dump a disk image’s cdhash, run the codesign tool as follows: % codesign -d -vvv DISK_IMAGE … CDHash=d963af703ac2e54af6609e9ad309abee7b66fae2 … Replace DISK_IMAGE with the path to your disk image. If the file used to install your app was a disk image but it wasn’t signed, switch to a signed disk image. It’s generally a better option. If the file used to install your app was an installer package (.pkg), there’s no good way to know if this is the correct package. In this case, modify your notarisation workflow to retain a copy of the file before it was modified by stapler. Tool Blocked by Gatekeeper If your product includes a command-line tool, you might notice this behaviour: When you double click the tool in Finder, it’s blocked by Gatekeeper. When you run the tool from within Terminal, it works. This is a known bug in macOS (r. 58097824). The issue is that, when you double click a tool in the Finder, it doesn’t run Gatekeeper’s standard execution logic. Rather, the Finder passes the tool to Terminal as a document and that opens a window (and associated shell) in which to run that document. This triggers Gatekeeper’s document logic, and that logic always blocks the tool. There are two ways around this: Embed your tool in an application. If the user runs the application first, Gatekeeper runs its normal application check. If the user allows the app to run, Gatekeeper records that decision and applies it to the app and any code within the app, including your tool. Install your tool using an installer package. When the user goes to install the package, Gatekeeper checks it. Assuming that check passes, Gatekeeper does no further checks on the content it installed. Revision History 2024-11-11 Added a mention of gktool. 2022-05-20 Added the Verify Your Signature section. Made other minor editorial changes.

I help a lot of developers with macOS trusted execution problems. For example, they might have an app being blocked by Gatekeeper, or an app that crashes on launch with a code signing error. If you encounter a problem that’s not explained here, start a new thread with the details. Make sure to add relevant tags — like Gatekeeper, Code Signing, and Notarization — so that I see your post. IMPORTANT macOS 14 has a new tool, syspolicy_check, that was specifically designed to help diagnose problems like this. I plan to update this post once I have more experience with it. In the meantime, however, if you hit a trusted execution problem and it reproduces on macOS 14, please try out syspolicy_check and let us know how that pans out. Share and Enjoy — Quinn “The Eskimo!” @ Developer Technical Support @ Apple let myEmail = "eskimo" + "1" + "@" + "apple.com" Resolving Trusted Execution Problems macOS supports three software distribution channels: The user downloads an app from the App Store. The user gets a Developer ID-signed program directly from its developer. The user builds programs locally using Apple or third-party developer tools. The trusted execution system aims to protect users from malicious code. It’s comprised of a number of different subsystems. For example, Gatekeeper strives to ensure that only trusted software runs on a user’s Mac, while XProtect is the platform’s built-in anti-malware technology. Note To learn more about these technologies, see Apple Platform Security. If you’re developing software for macOS your goal is to avoid trusted execution entanglements. You want users to install and use your product without taking any special steps. If, for example, you ship an app that’s blocked by Gatekeeper, you’re likely to lose a lot of customers, and your users’ hard-won trust. Trusted execution problems are rare with Mac App Store apps because the Mac App Store validation process tends to catch things early. This post is primarily focused on Developer ID-signed programs. Developers who use Xcode encounter fewer trusted execution problems because Xcode takes care of many code signing and packaging chores. If you’re not using Xcode, consider making the switch. If you can’t, consult the following for information on how to structure, sign, and package your code: Placing Content in a Bundle Embedding Nonstandard Code Structures in a Bundle Embedding a Command-Line Tool in a Sandboxed App Creating distribution-signed code for macOS Packaging Mac software for distribution Gatekeeper Basics User-level apps on macOS implement a quarantine system for new downloads. For example, if Safari downloads a zip archive, it quarantines that archive. This involves setting the com.apple.quarantine extended attribute on the file. Note The com.apple.quarantine extended attribute is not documented as API. If you need to add, check, or remove quarantine from a file programmatically, use the quarantinePropertiesKey property. User-level unarchiving tools preserve quarantine. To continue the above example, if you double click the quarantined zip archive in the Finder, Archive Utility will unpack the archive and quarantine the resulting files. If you launch a quarantined app, the system invokes Gatekeeper. Gatekeeper checks the app for problems. If it finds no problems, it asks the user to confirm the launch, just to be sure. If it finds a problem, it displays an alert to the user and prevents them from launching it. The exact wording of this alert varies depending on the specific problem, and from release to release of macOS, but it generally looks like the ones shown in Apple > Support > Safely open apps on your Mac. The system may run Gatekeeper at other times as well. The exact circumstances under which it runs Gatekeeper is not documented and changes over time. However, running a quarantined app always invokes Gatekeeper. Unix-y networking tools, like curl and scp, don’t quarantine the files they download. Unix-y unarchiving tools, like tar and unzip, don’t propagate quarantine to the unarchived files. Confirm the Problem Trusted execution problems can be tricky to reproduce: You may encounter false negatives, that is, you have a trusted execution problem but you don’t see it during development. You may also encounter false positives, that is, things fail on one specific Mac but otherwise work. To avoid chasing your own tail, test your product on a fresh Mac, one that’s never seen your product before. The best way to do this is using a VM, restoring to a snapshot between runs. For a concrete example of this, see Testing a Notarised Product. The most common cause of problems is a Gatekeeper alert saying that it’s blocked your product from running. However, that’s not the only possibility. Before going further, confirm that Gatekeeper is the problem by running your product without quarantine. That is, repeat the steps in Testing a Notarised Product except, in step 2, download your product in a way that doesn’t set quarantine. Then try launching your app. If that launch fails then Gatekeeper is not the problem, or it’s not the only problem! Note The easiest way to download your app to your test environment without setting quarantine is curl or scp. Alternatively, use xattr to remove the com.apple.quarantine extended attribute from the download before you unpack it. For more information about the xattr tool, see the xattr man page. Trusted execution problems come in all shapes and sizes. The remaining sections address the most common ones. App Blocked by Gatekeeper If your product is an app and it works correctly when not quarantined but is blocked by Gatekeeper when it is, you have a Gatekeeper problem. For advice on how to investigate such issues, see Resolving Gatekeeper Problems. App Can’t Be Opened Not all failures to launch are Gatekeeper errors. In some cases the app is just broken. For example: The app’s executable might be missing the x bit set in its file permissions. The app’s executable might be subtly incompatible with the current system. A classic example of this is trying to run a third-party app that contains arm64e code. macOS requires that third-party kernel extensions use the arm64e architecture. In other circumstances, stick to arm64 for your shipping products. If you want to test arm64e code locally, see Preparing Your App to Work with Pointer Authentication. The app’s executable might claim restricted entitlements that aren’t authorised by a provisioning profile. Or the app might have some other code signing problem. Note For more information about provisioning profiles, see TN3125 Inside Code Signing: Provisioning Profiles. In such cases the system displays an alert saying: The application “NoExec” can’t be opened. [[OK]] Note In macOS 11 this alert was: You do not have permission to open the application “NoExec”. Contact your computer or network administrator for assistance. [[OK]] which was much more confusing. A good diagnostic here is to run the app’s executable from Terminal. For example, an app with a missing x bit will fail to run like so: % NoExec.app/Contents/MacOS/NoExec zsh: permission denied: NoExec.app/Contents/MacOS/NoExec And an app with unauthorised entitlements will be killed by the trusted execution system: % OverClaim.app/Contents/MacOS/OverClaim zsh: killed OverClaim.app/Contents/MacOS/OverClaim In some cases running the executable from Terminal will reveal useful diagnostics. For example, if the app references a library that’s not available, the dynamic linker will print a helpful diagnostic: % MissingLibrary.app/Contents/MacOS/MissingLibrary dyld[88394]: Library not loaded: @rpath/CoreWaffleVarnishing.framework/Versions/A/CoreWaffleVarnishing … zsh: abort MissingLibrary.app/Contents/MacOS/MissingLibrary Code Signing Crashes on Launch A code signing crash has the following exception information: Exception Type: EXC_CRASH (SIGKILL (Code Signature Invalid)) The most common such crash is a crash on launch. To confirm that, look at the thread backtraces: Backtrace not available For steps to debug this, see Resolving Code Signing Crashes on Launch. One common cause of this problem is running distribution-signed code. Don’t do that! For details on why that’s a bad idea, see Don’t Run App Store Distribution-Signed Code. Code Signing Crashes After Launch If your program crashes due to a code signing problem after launch, you might have encountered the issue discussed in Updating Mac Software. Non-Code Signing Failures After Launch The hardened runtime enables a number of security checks within a process. Some coding techniques are incompatible with the hardened runtime. If you suspect that your code is incompatible with the hardened runtime, see Resolving Hardened Runtime Incompatibilities. App Sandbox Inheritance If you’re creating a product with the App Sandbox enabled and it crashes with a trap within _libsecinit_appsandbox, it’s likely that you’re having App Sandbox inheritance problems. For the details, see Resolving App Sandbox Inheritance Problems. Library Loading Problem Most library loading problems have an obvious cause. For example, the library might not be where you expect it, or it might be built with the wrong platform or architecture. However, some library loading problems are caused by the trusted execution system. For the details, see Resolving Library Loading Problems. Explore the System Log If none of the above resolves your issue, look in the system log for clues as to what’s gone wrong. Some good keywords to search for include: gk, for Gatekeeper xprotect syspolicy, per the syspolicyd man page cmd, for Mach-O load command oddities amfi, for Apple mobile file integrity, per the amfid man page taskgated, see its taskgated man page yara, discussed in Apple Platform Security ProvisioningProfiles You may be able to get more useful logging with this command: % sudo sysctl -w security.mac.amfi.verbose_logging=1 Here’s a log command that I often use when I’m investigating a trusted execution problem and I don’t know here to start: % log stream --predicate "sender == 'AppleMobileFileIntegrity' or sender == 'AppleSystemPolicy' or process == 'amfid' or process == 'taskgated-helper' or process == 'syspolicyd'" For general information the system log, see Your Friend the System Log.

Hi Apple community, many thanks in advance for your help. My macOS app embeds a Python interpreter, compiled from source, including the Python executable and its associated libraries. We have tried compiling the project with Xcode 16.0 and 16.1 beta 2 over MacOS Sequoia 15.0 and 15.1 This is how the project looks like: SampleApp.app SampleApp.app/Contents SampleApp.app/Contents/MacOS SampleApp.app/Contents/MacOS/SampleApp SampleApp.app/Contents/MacOS/bin SampleApp.app/Contents/MacOS/bin/python3.11 SampleApp.app/Contents/Resources SampleApp.app/Contents/Resources/lib SampleApp.app/Contents/Resources/lib/python3.11 SampleApp.app/Contents/Resources/Info.plist Since we want to 'initially' distribute the app directly, Python binary is signed as follows: codesign --deep --force --options runtime --timestamp --sign "$DEVELOPER_ID_APPLICATION" "$BINARY_PATH" App entitlements contain the next entries: &amp;lt;key&amp;gt;com.apple.security.app-sandbox&amp;lt;/key&amp;gt; &amp;lt;true/&amp;gt; &amp;lt;key&amp;gt;com.apple.security.files.downloads.read-write&amp;lt;/key&amp;gt; &amp;lt;true/&amp;gt; &amp;lt;key&amp;gt;com.apple.security.files.user-selected.read-only&amp;lt;/key&amp;gt; &amp;lt;true/&amp;gt; &amp;lt;key&amp;gt;com.apple.security.files.user-selected.read-write&amp;lt;/key&amp;gt; &amp;lt;true/&amp;gt; &amp;lt;key&amp;gt;com.apple.security.network.client&amp;lt;/key&amp;gt; &amp;lt;true/&amp;gt; &amp;lt;key&amp;gt;com.apple.security.network.server&amp;lt;/key&amp;gt; &amp;lt;true/&amp;gt; The resulting app is signed with entitlements, notarised and stapled.

Hi Apple community, many thanks in advance for your help. My macOS app embeds a Python interpreter, compiled from source, including the Python executable and its associated libraries. We have tried compiling the project with Xcode 16.0 and 16.1 beta 2 over MacOS Sequoia 15.0 and 15.1. The project is 100% developed in Swift6. This is how the project looks like: SampleApp.app SampleApp.app/Contents SampleApp.app/Contents/MacOS SampleApp.app/Contents/MacOS/SampleApp SampleApp.app/Contents/MacOS/bin SampleApp.app/Contents/MacOS/bin/python3.11 SampleApp.app/Contents/Resources SampleApp.app/Contents/Resources/lib SampleApp.app/Contents/Resources/lib/python3.11 SampleApp.app/Contents/Resources/Info.plist Since we want to 'initially' distribute the app directly, Python binary is signed as follows: codesign --deep --force --options runtime --timestamp --sign "$DEVELOPER_ID_APPLICATION" "$BINARY_PATH" App entitlements contain the next entries: &lt;key&gt;com.apple.security.app-sandbox&lt;/key&gt; &lt;true/&gt; &lt;key&gt;com.apple.security.files.downloads.read-write&lt;/key&gt; &lt;true/&gt; &lt;key&gt;com.apple.security.files.user-selected.read-only&lt;/key&gt; &lt;true/&gt; &lt;key&gt;com.apple.security.files.user-selected.read-write&lt;/key&gt; &lt;true/&gt; &lt;key&gt;com.apple.security.network.client&lt;/key&gt; &lt;true/&gt; &lt;key&gt;com.apple.security.network.server&lt;/key&gt; &lt;true/&gt; The resulting app is signed with entitlements, notarised and stapled. Once the app is running, we can see the next errors on Console: Prompting policy for hardened runtime; service: kTCCServiceAppleEvents requires entitlement com.apple.security.automation.apple-events but it is missing for accessing={TCCDProcess: identifier=[IDENTIFIER]], pid=58826, auid=502, euid=502, binary_path=[PATH]}, requesting={TCCDProcess: identifier=com.apple.appleeventsd, pid=824, auid=55, euid=55, binary_path=/System/Library/CoreServices/appleeventsd}, Python process runs for some seconds and then the process disappears. We can not see any AMFI message on Console. Then we add to Signing and Capabilities 'Apple Events' from Hardened Runtime section.

The actual error: pkgbuild: error: Could not find appropriate signing identity for “Developer ID installer: My Name (DeveloperID)”. I'm trying to sign a program written with gfortran. The steps worked the last time (Mar 23) I built this code. The steps to error: a) xcrun notarytool store-credentials --apple-id "***" --team-id "yyy" Giving Profile Name zzz and App-specific password b) codesign --force --timestamp --options=runtime -s "Developer ID Application: My Name (yyy)" AppName c) pkgbuild --root ROOT --identifier org.aaa.bbb --version "1.1.1" --sign "Developer ID installer: My Name (yyy)" AppName.pkg ROOT contains the package contents At this point I get the error pkgbuild: error: Could not find appropriate signing identity for “Developer ID installer: My Name (yyy)” Are there steps that have changed. Any suggestions? Thanks, David

Hi, I have an Electron app that I build, sign, notarize, and staple using electron-builder. It includes Sound Exchange (SoX), which I was invoking from the homebrew installed version. It builds a dmg and works fine. However, my users are non-technical, thus cannot be expected to install dev tools, homebrew, and sox from the command line and set paths. Therefore, I need to include a SoX binary in my app. I have a static SoX binary that works. However, when I try to run it from my electron app, I get Error: spawn / <path>/sox EACCES. Electron-builder is signing the SoX binary codesign --sign <sign number> --force --timestamp --options runtime --entitlements dist/entitlements/entitlements.mac.plist /<app path>Contents/Resources/bin/sox/sox The app sign/notarize works fine, the dmg mounts, and the app runs until I try to invoke SoX. Also, I verified the sox binary and entire app are signed and the app staple is valid. I am running the app from /Applications. Please help me!

Hi, I've recently observed a sudden increase in support requests for one of my apps on the Mac App Store, reporting the error " is damaged and can't be opened. Please re-download it from the Mac App Store", all on different systems: macOS 12, macOS 13, and macOS 15 Sequoia. Re-downloading does not resolve the issue most of the time. One user reported that being connected to the internet resolved it - perhaps this is an OCSP issue again? I myself cannot reproduce this issue. Has there been a change in code-signing recently? Have some certificates changed? Anything else I should be aware of? What is the best course of action to have users take who experience this, when re-downloading the app from the Mac App Store does not work? Thank you, – Matthias

I have tried to manually install binaries using Finder by clicking and dragging from the Desktop into "/usr/local/bin/". The binaries come with a collection of frameworks etc. All the binaries are adhoc signed. macOS asks for Admin credentials which is fine. But then, when I execute the binaries in Terminal, Gatekeeper shows the now expected "'[binary"] Not Opened Apple could not verify ........" etc. It shows that dialog for every component and requires user input 2-3 times to allow each component of which there are perhaps dozens. BUT, none of that happens if I install those binaries using AppleScript. So, it might have a call like this: do shell script "curl -L " &amp; download_URL &amp; " -o " &amp; download_binary_zip with administrator privileges do shell script "unzip -o " &amp; download_binary_zip &amp; " -d " &amp; usr_bin_folder with administrator privileges The resulting installs work perfectly. Is this intended ? Using both install methods requires Admin credentials. Why does using a script work but using Finder does not ?
