Apps made with Adobe Animate.
Adobe says that Animate works with the latest Mac OS. When I publish apps with Animate, they work on my computer. With a self-signed certificate, they work on some older Mac OS versions, but not on the 2 most recent. How can I test my apps on others' Mac computers? Robert

Questions about enterprise-wide signing of IPAs
I work with a team that is responsible for our company's centralized infrastructure for code signing various products within our portfolio, including iOS apps. For security purposes, we want to sign apps before their posting on the App Store, and also to log this activity for eventual security audits. Not surprisingly, we need automated processes; we can't use an IDE like Xcode to do the work. We must queue, process, and log all signing jobs, and have Macs dedicated to this purpose. I can't go into many details about our infrastructure due to confidentiality concerns, so I'll apologize now if my questions seem a little vague. We currently require our iOS developers to submit one or more new provisioning profiles as well as their IPA archive for signing. We support supplying multiple provisioning profiles because some of our developers include embedded third-party extensions within their IPAs, and these extensions can also have their own provisioning profiles. Within our back end, we open the archive, sign the relevant portions using the entitlements in one of the profiles (that we believe to be the appropriate one for the particular archive element), overwrite each supplied provisioning profile with (what we believe to be) the appropriate one from user input, and re-compress the archive. Here come the questions: When we receive multiple provisioning profiles, how do we know which profile should be used to help with signing which archive elements? What data (e.g. entitlements application-identifier, team-identifier) can we use? We also need to know which provisioning profiles from their input correspond to those that already exist within the archive. What data can we use to map profiles from one set to the other? Should we be requiring our users to submit new provisioning profiles in the first place? Or should we edit/recycle the existing ones in some way? We'd like to remove any unnecessary burdens for our users, if possible.

signing and certificate
Hi, I'm currently developing a Flutter app that utilizes Push Notifications. The Android implementation is working flawlessly, but I'm encountering compilation issues in Xcode. Specifically, I'm receiving the following error: Cannot create a iOS App Development provisioning profile for "dk.ceniconsulting.alarm". Personal development teams, including "Henrik Thystrup", do not support the Push Notifications capability. No profiles for 'dk.ceniconsulting.alarm' were found Xcode couldn't find any iOS App Development provisioning profiles matching 'dk.ceniconsulting.alarm'. This error seems to be a common issue, but I haven't been able to find a definitive solution. I've already generated a certificate, identifier, and installed them, but the problem persists. Does anyone have any insights or suggestions on how to resolve this issue? Or perhaps a link to a resource that addresses this specific problem?

Xcode Build for React App fails in codesigning step
I tried building the React App for Any iOS device (Arm64) but I get error. Although I can build successfully for any iOS Simulators In the codesigning step I get the following error, "Warning: unable to build chain to self-signed root for signer "Apple Development: my email address ( ... ) " I don't have paid membership of Apple Developer Program, does that cause this failure? Also, to archive also do I need Apple Developer Program paid membership?

Pkg installation package uploaded to macstore email prompt ITMS-90296
Project Background: I developed a Mac project using Electron and VSCode Successfully uploaded the packaged pkg using Transporter, However, I will receive an email informing me that there are some issues with the project: ITMS-90296: App sandbox not enabled - The following executors must include the 'com. apple. security. app sandbox' entitlement with a Boolean value of true in the entitlement property list: [[com. electron. iflyrecclient. pkg/Payload/iFlytek Listen. app/Contents/MacOS/iFlytek Listen]] ITMS-90886: 'Cannot be used with TestFlight because the signature for the bundle at' iFlytek hears. app 'is missing an application identifier but has an application identifier in the provisioning profile for the bundle.' Bundles with application identifiers in the provisioning profile are expected to have the same identifier signed into the bundle in order to be eligible for TestFlight.' Here is my packaging process: Generate an app using the electron packager tool Sign the app using @ electron osx sign (version 1.3.1) After signing, use productbuild - component Yourappname App/Applications - sign "3rd Party Mac Developer Installer: * * * * * (XXXXXXXXXX)" Yourappname. pkg command generates pkg PS: For the second step, I have set sand box=true in both entitlents.plist and entitlents.macinheriting. plist. And after signing, using codesign -dvvv -- entitiements - /path to view the app file shows' checkbox=true ', and the [iFlytek Listen. app/Contents/MacOS/iFlytek Listen] file in the issue also exists. Using the Suspicious Package software to view pkg also has sandbox=true. A few months ago, I uploaded it once and the issues mentioned in the email did not appear. The only changes were the macOS system version number and the replacement of the signature with provisionprofileprovisionprofile. I have reviewed similar issues on the Apple Developer Forums, but have not been resolved

How can I share a developer-signed app through my website?
In the past, I used to export a developer-signed test version of my macOS app in Xcode, create a zip archive from the Finder, upload it to my website and share the link to the testers. The last time I did this with macOS 14 the tester was still able to download the test app and run it. But it seems that with macOS 15 the trick to open the context menu on the downloaded app and click Open to bypass the macOS warning that the app couldn't be checked when simply double-clicking it, doesn't work anymore. Now I'm always shown an alert that macOS couldn't check the app for malware, and pushes me to move it to the bin. In this StackOverflow topic from 10 years ago they suggested to use ditto and tar to compress and uncompress the app, but neither worked for me. How can I share macOS apps that I signed myself with testers without physically handing them a drive containing the uncompressed app?

Unable to Write Files Within App Bundle After Codesigning and Notarization
Codesigned and notarized app cannot directly write files inside the app bundle (neither in my.app/Contents/Resources/ nor my.app/Contents/MacOS/). Are there any restrictions regarding this? Is there a way to bypass these restrictions? Here is the situation I encountered: The main app contains several sub-apps and sub-executables. When the main app calls the sub-apps or sub-executables, it can write files within the app bundle, but when executed directly, it cannot write files. The app is usually opened using the GUI, and when using the command line, neither the main app nor the sub-apps/sub-executables can write files within the app bundle. My codesigning environment is: Sonoma 14.0 on mac mini M1. I manually sign the app directly using the codesign command in CI instead of using Xcode. The process will traverse all of the files and sub-apps in the app folder and sign them from the deepest paths to the shallowest paths. I also tried applying this process to other applications, but all of them encountered the same issue of failing to write files. The app should not be sandboxed (I did not add sandbox entitlements). I have tried adding the entitlement com.apple.security.files.user-selected.read-write, but this has not resolved the issue.

App Fails spctl After signing and notarization
I have an app Arpeggio.app which I build and then sign without errors: "electron-osx-sign dist/mac-arm64/Arpeggio.app --identity="Developer ID Application: XXXX (XXXXXX)" --hardened-runtime --no-gatekeeper-assess --entitlements=entitlements.plist". It returns "Application signed: dist/mac-arm64/Arpeggio.app". I then use "/usr/bin/ditto -c -k --sequesterRsrc --keepParent src dst" to make a zip with the same signatures. I then submit the zip for notarization: "xcrun notarytool submit dist/mac-arm64/Arpeggio.zip --apple-id XXXX etc" which returns "Waiting for processing to complete. Current status: Accepted.............. Processing complete id: ***-***-xx-xx status: Accepted". Then I staple the notarization to the app and get "The staple and validate action worked!". Now it shows all validated and that the notarization is stapled. I then run "spctl --assess --type execute -vv 'dist/mac-arm64/Arpeggio.app'" as a last check and always get this: dist/mac-arm64/Arpeggio.app: unknown error 99999=1869f Why is this happening? I can't seem to debug the issue but out notarization and signing is always successful and the app works as expected. Pleas ehelp me get to the bottom of this.

Cannot install release test (ad-hoc profile) on Vision Pro
I was able to setup a release test for an iOS app for distribution using a web server. It works perfectly fine for all the devices I registered for the deployment profile. However every time I try to distribute a Unity based Vision Pro application using the same process for building the package and set up for distribution it does not work. Safari only shows a message telling me: "Cannot connect to ." When trying to install the iOS app from the same server it shows the message "Do you want to install ?" and installation completes correctly. My iOS is a simple hello world app generated by Xcode. My Unity app is an AR app targeting com.apple.platform.xros. According to documentation there should not be any difference in deployment profiles/signing for iOS apps vs. visionOS apps. What am I doing wrong? Any hint is appreciated how to continue.

"Command CodeSign failed with a nonzero exit code" after enrollment to a development team
Hi all, I have two apple accounts. Stupidly my project is written in Account A and my paid developer account is Account B. When I tried to archive and publish under Account A, it says "Team "*** (Personal Team)" is not enrolled in the Apple Developer Program". But when I add a team to Account B, "Command CodeSign failed with a nonzero exit code". I know it is not the code itself because it runs fine when I use Account A. Just couldn't publish. Any advice? Many many thanks

xcodebuild is very slow unless you set CODE_SIGNING_ALLOWED=NO"
Incremental builds using xcodebuild are very slow, around 3x slower when compared to the same build using Xcode. Recently, I discovered that CODE_SIGNING_ALLOWED=NO" fixed the issue, but of course, I can't then run iOS app. It seems like automatic signing using xcodebuild is somehow broken. Therefore, I think I could set CODE_SIGNING_ALLOWED=NO" and sign it manually later. However, I'm not sure how to do that. I checked what Xcode does and it's: /usr/bin/codesign --force --sign - --entitlements /Users/wkulik/Library/Developer/Xcode/DerivedData/XYZ-hblnhsksxjrctzekqmlevcflnsji/Build/Intermediates.noindex/XYZ.build/Debug-iphonesimulator/XYZ.build/XYZ.app.xcent --timestamp\=none --generate-entitlement-der /Users/wkulik/Library/Developer/Xcode/DerivedData/XYZ-hblnhsksxjrctzekqmlevcflnsji/Build/Products/Debug-iphonesimulator/XYZ.app However, if I run xcodebuild with disabled signing I don't have XYZ.app.xcent required by this command. I also tried: codesign --force --deep --sign "Apple Development: John Snow (XYZ)" /Users/wkulik/Library/Developer/Xcode/DerivedData/XYZ-hblnhsksxjrctzekqmlevcflnsji/Build/Products/Debug-iphonesimulator/XYZ.app but the app immediately terminates (the same way like when unsigned). Could anyone help with that?

27/10000AI翻译 划译 The APP packaged with enterprise certificate has a flashback phenomenon under ios18 system
I found a post that submitted the same issue, but the solution was not made public. I didn't get a reply to my comment at the bottom of the post, so I'm pasting the content of the post here. I am a developer working on iOS apps. I would like to report an issue occurring in iOS 18 beta and iOS 18.1 beta. Our company has two Enterprise accounts, and we are developing two apps: A app / TeamId: ABCDEFG B app / TeamId: HIJKLMN When we distribute these apps, which have different TeamIds, and install them on a device running iOS 18 beta, both apps install successfully, but only one app will run. (Other app crashed immediately after being launched.) This issue does not occur on versions prior to iOS 18. I would like to know if this is a problem that will be resolved in future updates, or if it is a policy change.

“a sealed resource is missing or invalid” on an installed, notarized application
We have a native ARM64 application. The application is a development environment and native compiler for the language Common Lisp. CL has a foreign function interface, which allows loading of .dylib files into CL and calling functions in them from CL. For this reason, we add certain entitlements. See below. It is notarized and installed on macOS 14.7. When I run spctl on it I get this: $ spctl --assess -v /Applications/AllegroCL64.app /Applications/AllegroCL64.app: rejected (the code is valid but does not seem to be an app) That’s before I run it. Which is odd because the app is notarized. When I run the app, it asks for a license file and installs it into /Applications/AllegroCL64.app/Contents/Resources/ and after that, the spctl shows this: $ spctl --assess -v /Applications/AllegroCL64.app /Applications/AllegroCL64.app: a sealed resource is missing or invalid I assume the mere act of copying the license (a file called devel.lic which is a small text file) is causing this. Why does it say it “does not seem to be an app”? This self-modification of the files in the Contents/Resources directory is a huge feature. We allow downloading of patches, which add features and fix bugs in the product. Is this going to be a problem, going forward? I don’t remember seeing this result from spctl before and I have a feeling it’s a new , due to tightening of security policies, etc. All of this is quite worrying to us. More details of the app: $ codesign -vvvv mlisp mlisp: valid on disk mlisp: satisfies its Designated Requirement $ codesign -d --entitlements - /Applications/AllegroCL64.app Executable=/Applications/AllegroCL64.app/Contents/MacOS/AllegroCL64 [Dict] [Key] com.apple.security.cs.allow-dyld-environment-variables [Value] [Bool] true [Key] com.apple.security.cs.allow-jit [Value] [Bool] true [Key] com.apple.security.cs.disable-library-validation [Value] [Bool] true [Key] com.apple.security.get-task-allow [Value] [Bool] true $ Other details: The app was built with the Command Line tools version 2395 on macOS 12.x.

Append data of personalized installer
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?
