I'm on MacOS 12.1 i've tried: ProcessInfo.processInfo.performActivity(options: [.idleDisplaySleepDisabled, .userInitiated], reason: "...") IOPMAssertionCreateWithName(kIOPMAssertionTypeNoDisplaySleep as CFString, UInt32(kIOPMAssertionLevelOn), "..." as CFString, &assertionID) IOPMAssertionDeclareUserActivity("..." as CFString, kIOPMUserActiveLocal, &self.assertionID) they all prevent display sleep fine however, neither of these prevent the screen saver ("Preferences>Desktop & Screen Saver") from starting at a loss, have no idea other than to tell users to turn off the screen saver. if they have display sleep turned on they shouldn't be needing it ever anyways.

ok, so this API is gone, but what is the reasoning for CTTelephonyNetworkInfo.serviceSubscriberCellularProviders to also always return an object and never update regardless of whether a SIM is actually inserted? Why aren't developers allowed to know whether a SIM is present at all?

I have this problem in override func setValue(_ value: Any?, forKey key: String) { ... } how can i pass sendable values such as primitive types to a main actor isolated function?
