site_archiver@lists.apple.com Delivered-To: installer-dev@lists.apple.com Hi, In my installer plugin code, I display an alert by using NSAlert. In this alert, I have a button which, when clicked, should exit the installer. This works fine on OSes prior to Catalina, but on Catalina, the installer hangs when clicking on this button. To exit the installer, I have tried the following six alternatives: exit(EXIT_SUCCESS); exit(EXIT_FAILURE); [[NSApplication sharedApplication] terminate:nil]; [[NSApplication sharedApplication] terminate:self]; [NSApp terminate:self]; [NSApp terminate:nil]; However, they all result in a hang (again, only on Catalina). For example from the console log when calling [NSApp terminate:nil]: default 15:33:16.841249-0700 distnoted unregister token: f4260 pid: 11340 default 15:33:16.841301-0700 distnoted unregister token: f425f pid: 11340 error 15:33:16.843817-0700 WindowServer CGLayerKit called back to a dead connection default 15:33:16.843990-0700 hidd Connection removed: IOHIDEventSystemConnection uuid:E9477186-1BC5-48C2-AC7E-F34BDEB7AFFD pid:11340 process:InstallerRemotePluginService type:Passive entitlements:0x0 caller:HIToolbox: ___GetIOHIDEventSystemClient_block_invoke + 26 attributes:(null) inactive:1 events:0 mask:0x0 error 15:33:16.844238-0700 WindowServer CGLayerKit called back to a dead connection default 15:33:16.847986-0700 runningboardd [executable<InstallerRemotePluginService(501)>:11340] Death sentinel fired! default 15:33:16.848452-0700 launchservicesd QUITTING: pid=11340 asn=0x-0x189189 foreground=0 wasFront=0 default 15:33:16.850220-0700 CommCenter #I handleLSNotitifcation_sync: Application exited: <private> default 15:33:16.851097-0700 loginwindow -[PersistentAppsSupport applicationQuit:] | for app:InstallerRemotePluginService (Installer), _appTrackingState = 2 default 15:33:16.850615-0700 runningboardd Invalidating assertion 324-133-1049 (target:executable<InstallerRemotePluginService(501)>) from originator 133 default 15:33:16.952295-0700 runningboardd Removing process: [executable<InstallerRemotePluginService(501)>:11340] default 15:33:16.956649-0700 runningboardd Removing assertions for terminated process: [executable<InstallerRemotePluginService(501)>:11340] I can also provide a [lengthy] .hang file if that would help. Anyone have any suggestions on how to fix this? Any help would be greatly appreciated. Thanks, Lora _______________________________________________ Do not post admin requests to the list.
