Hello, is there something to do for developers for the M1 Ultra chip to use all GPU cores? When you output the power used, you may see that with heavy load, the GPU may not use full 120 W of power and it looks like some GPU cores may be idle. Is some entitlement needed, something for configuration? Or how can you get maximum performance there? Greetings Christian

Hello, project works fine in Xcode 12.5.1, but when I open it in 13.1 to test, I get error when hitting build. First it was an error with "unknownSession", but after cleaning, I now have a crash: Prepare build note: Using new build system note: Planning unexpected service error: The Xcode build system has crashed. Build again to continue.error: unexpected service error: The Xcode build system has crashed. Build again to continue.

Anyone has an idea why the app may crash with a code signing issue loading the TCC.framework? That is part of WKPreferences checking for microphone access. The application is code signed and launches without problems. Just when this code comes to initialize WebKit, it crashes.

Hello,I am looking for details on requestAuthorizationOfType in NSWorkspace class.And NSFileManager fileManagerWithAuthorization function related to it.Is this supposed to work in any application or is it only for sandbox or only for Mac App Store?Even without code signing or entitlement, I get the authorization dialog asking for password.But I can't make it to work at all when setting file attributes.This would be nice to replace some deprecated Authentication functions we use.

Hi,We distribute libraries for developers. A download contains both Mac and iOS frameworks for developers to use.Now we notarize the dmg and get an error: "Unable to notarize .../test.framework/test",So the iOS bundle is not ignored. How can we get the iOS part notarized, too? Or ignored?SincerelyChristian

Hello,we like to distribute some data files to clients as dmg, so metadata like custom icons survive.How can we notarize such a dmg, so users can open them easily without having an app inside the dmg?SincerelyChristian
