Hi Lora,

As I pointed out in my previous posts, Installer plugins are running outside of the Installer process so all the ext()/NSApp.terminate/etc calls are dealing with another process hosting the plugin, not Installer itself.

You still can use brute force kill command though

system("killall -9 Installer");

Cheers V.

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]:

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
