I am trying to develop a custom plugin. Below is my auth plugin plist. However, the mechanism marked as privileged is not being triggered by macOS. If I remove the privilege, it gets called. Any pointers on this? TestPlugin:MyLogin and TestPlugin:MyUser,privileged are my custom plugins. <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>class</key> <string>evaluate-mechanisms</string> <key>comment</key> <string>Login mechanism based rule.

We've got a non-sandboxed app with a built-in daemon that does some root-privileged things for us on occasion. We're using the newest SMAppService APIs, using NSXPCConnections for communications, and generally things work as expected. The daemon is set up to terminate when the parent app terminates. Our app also has (and uses the daemon for) a self-update feature. Once the new app is downloaded, the daemon takes over, replaces the app in-place, terminates the old app and launches the new one. However, after this update, the daemon no longer works. Any other build & launch of the app will silently fail when trying to talk to the daemon. The XPC connection can be constructed as usual, no errors, the process goes along like it should app-side, but the daemon never actually launches and never responds. I can imagine there could be a few rules being broken here with the self-update and the built-in daemon, but what would they be and how can we work within the rules?

I am working with a compiler that produces native binaries, It's really meant for servers so it's not integrated with Xcode or the Xcode build system. As such the output binaries get the default ad-hoc signatures the linker makes. After (re)compiling such a binary, there is a delay whilst running it. This is because macOS notices it's an unknown binary and goes off to ask notarization servers/Xprotect if it's known malware. Fine, I understand the need for this and why it happens. From the logs it's clear that macOS is now tracking the "provenance" of binaries. This means where they came from. This raises the question of whether it could know that my local dev binaries are coming from this compiler, if it was in turn properly signed and notarized. And if so, whether there is some security policy I could set to say "if binary X produces binary Y, then trust Y". Yes I know this would be a security exploit if it were done that way by default, but I am willing to take the risk of special malware that compiles itself first using this special compiler that isn't installed by default then runs the output, as presumably any such malware would be so targeted Xprotect/notarization wouldn't know about it anyway. The provenance mechanism is some internal security thing and isn't documented, but I'm curious if anyone knows more about it and whether it's usable for this? Or alternatively if there's a way to stop macOS doing these slow checks for certain binaries e.g. under specific paths?

I know how to set up a parental gate to keep a child user away from a web portal for parents or guardians. But is it even OK with Apple (or just in general) to open a browser from inside a kids app? I can think of two ways to do this: Launch a browser with UIApplication.shared.open(). This takes the user (presumably an adult) out of the app. Will Apple object to this? Use an in-app browser with WKWebView. (Wrapped in UIViewRepresentable because I'm using SwiftUI.) Option 2 has some problems with Google SSO, which is a requirement for me. Some details in stackoverflow 2016 and stackoverflow 2019 and gitHub. I can't figure out how to apply the solutions in those posts to the SwiftUI architecture or even the UIViewRepresentable.

my macOS process is crashing when i keep my mac sleep for about 1 hour. Under Crash Reports, Console app shows two type of file. .diag type .ips type ips file doesn't shows exact line of crash as you can see below sample.

Hello, Regarding authorization plugins, I am trying to display a user interface in the fast user switching (fus) scenario. I have implemented the SFAuthorizationPluginView class that theoretically would help me show a user interface in this context. doing tests, I see that my plugin window is displayed behind the fus background screen. This window in screen lock scenario is displayed correctly. Is there any limitation in fus that prevents displaying a UI above the background screen where the user enters the password? I show how I have system.login.fus configured(My plugin is MyTestPlugin): ... mechanisms <string>builtin:smartcard-sniffer,privileged</string> <string>loginwindow:login</string> <string>builtin:reset-password,privileged</string> <string>builtin:auto-login,privileged</string> <string>builtin:authenticate-nocred,privileged</string> <string>MyTestPlugin:invoke</string> <string>loginwindow:success</string> <string>loginwindow:done</string> I have tried placing my puglin in a different order compared to other mechanisms and it did not get the window to display above the background screen. Another option I've tried is to place my plugin on top of loginwindow:login. In this case, my plugin interface is displayed correctly but I do not have username information. Is there a way to obtain this information? All the best.

I am working on a Swift app which does a TLS connection to a server. I want to set an identity, which the server will validate. I'm given a pkcs12 file. The cert is not trusted locally on my system, but the server can validate it. First, I didn't need to import the cert - I just want to create an identity that I can use with my connection. I don't think that's possible, so I do this: var importStatus = SecPKCS12Import(pkcs12Data as CFData, importOptions as CFDictionary, &importArray) The first time I call this, it's successful. I have come to extract the identity (and certificate) from the importArray returned, but in my case, even though I get an errSecSuccess return status, the importArray is empty. So first question: why would it be empty? ( if the code is run again, I get an errSecDuplicateItem - I don't need to store it in the keychain but I guess I'm being forced to) When I imported, I used a UUID as my identifier - I set it in the options: let importOptions: [String: Any] = [ kSecImportExportPassphrase as String: password, kSecImportItemLabel as String: identifier ] So I try to retrieve the identity from the keychain: let identityQuery = [ kSecClass: kSecClassIdentity, kSecReturnRef: true, kSecAttrLabel: identifier ] as NSDictionary var identityItem: CFTypeRef? let status = SecItemCopyMatching(identityQuery as CFDictionary, &identityItem) where I pass the UUID as identifier, but I actually get back my apple identity, not the certificate. However, if I pass in the certificate's CN, (hard-coded for my testing) I get the right identity back. So my second question: am I doing something wrong? If i pass an ItemLabel on import, can I retrieve the certificate using that same label? So for me to get this working, I need to know the CN of my cert, or I need the ItemLabel to work so that I can just retrieve using a UUID. To determine the CN of my cert, the only apple API I found is this: SecCertificateCopyCommonName which requires the cert to be in .der format, rather than .pkcs12. So I have a bit of a chicken and egg problem. So my last question - is there a way to extract the CN from the pkcs12 file, or to convert the Data from .pkcs12 to .der? Thanks!

I have created a custom username/password lock screen using SFAuthorizationPluginView. When lock the screen the view appears. The cursor start blinking in TextField. However, it always automatically dismiss in 20 second if ideal. I could see the Mechanism dealloc gets called and dismiss the view. Based on my investigation, I think the system kill the view in 20second, and there is no ways to increase that and keep the custom screen for more time. Any help will be appreciate.
