Ok, I guess I fixed it, for now. Even though i'd tried rebooting the Mac, closing Safari then trying this login did in fact open Safari correctly. It even presented me with the 30+ login windows that had previously not opened. So it's working again now, but I don't know why it got stuck.

Did you have any luck with this? I am developing an iOS 15+ SwiftUI app and want to display the BluetoothAccessoryPicker but it just does not show! I've tried adding the AppDelegate to my app and try to show the picker using: try await manager.showBluetoothAccessoryPicker(withNameFilter: nil) But I get nothing, just these lines in the console log: 2021-10-18 11:47:52.905742+0100 MyApp[18402:2620972] IAPAppRegisterClient: capabilities 0x8030 2021-10-18 11:47:52.906019+0100 MyApp[18402:2620972] IAPAppRegisterClient: __eaClientRegisterediapd 0 -> 1 2021-10-18 11:47:52.906085+0100 MyApp[18402:2620972] IAPAppRegisterClient: __eaClientRegisterediap2d 0 -> 1 2021-10-18 11:47:52.906700+0100 MyApp[18402:2620972] IAPDHasLaunched: kIAPAvailableNotification iapdAvailableState 100 -> 0 2021-10-18 11:47:52.906806+0100 MyApp[18402:2620972] IAPAppRegisterClient: __eaiapdHasClientID 0, IAPDHasLaunched 0 2021-10-18 11:47:52.907168+0100 MyApp[18402:2620972] IAP2DHasLaunched: kIAP2AvailableNotification iap2dAvailableState 100 -> 0 2021-10-18 11:47:52.907238+0100 MyApp[18402:2620972] IAPAppRegisterClient: __eaiap2dHasClientID 0, IAP2DHasLaunched 0 2021-10-18 11:47:52.907416+0100 MyApp[18402:2620972] IAPAppRegisterClient: registerWasSuccessful 0 2021-10-18 11:47:52.907716+0100 MyApp[18402:2620972] -[EAAccessoryManager _initFromSingletonCreationMethod] isRunningOnMac 2021-10-18 11:47:52.910422+0100 MyApp[18402:2620972] IAPAppConnectedAccessories: __eaClientHasCheckedForConnectedAccessories 0 -> 1 2021-10-18 11:47:52.910760+0100 MyApp[18402:2620972] IAPAppConnectedAccessories: IAPDHasLaunched 0, IAP2DHasLaunched 0 2021-10-18 11:47:54.170507+0100 MyApp[18402:2620954] Writing analzed variants.

I’m trying to run my iOS app unmodified on an M1 Mac. So that explains why the macCatalyst check doesn’t pass. But why does the iOS 15+ check succeed when it even reports it’s running as iOS 14.7?

I've been having the same today updating Numbers, Pages and iMovie. Each one has taken many hours to install!

Ok, it seems this only happens when building for the simulator. Which isn't really an issue. When I archive the app, it builds with bitcode just fine.
