Hello! We rely on applications launch date information provided by NSWorkspace. Our main applications of interest are browsers (Safari, Chrome, Firefox). We've noticed that NSWorkspace on Big Sur returns nil for all running applications including those that we are primarily interested in. This can be easily reproduced with the code sample below [[[NSWorkspace sharedWorkspace] runningApplications] enumerateObjectsUsingBlock:^(NSRunningApplication * _Nonnull obj, NSUInteger idx, BOOL * _Nonnull stop) { NSLog(@App %@ launched at %@, obj.bundleIdentifier, obj.launchDate); }]; The issue is observed in all released beta builds of Big Sur including the latest beta 4. Submitted the same report in feedback assistant: FB8098936 Will this be fixed? Or we should start thinking of alternative approaches for getting the launch date? Thanks. Best regards, Arthur
