It might also help if we knew why the OP needed to force a pop up instead of
utilizing the custom install UI.

Important side note that installer plug-ins do not execute when the package is
executed via CL (like is commonly done via Jamf or other deployment suites). If
the only thing that the plugin is doing is tossing a dialog, it may be worth
looking into other ways to do that from within the preinstall or postinstall
scripting.

And while Installer.app will queue multiple packages, it can (without taking
extraordinary measures) only have one open instance, so should be pretty
safe with a kill command to end it specifically.

No, it will kill only UI-based Installer (spelled with uppercase I)
and user-experience-wise is in parity with the exit()/terminate/etc you
have been using before...
The command-line installer is spelled with lower-case "i" and will not be
affected by kill command.

Thanks for your reply, Vachik. The issue with calling system("killall -9
Installer”) is that if other installers are running simultaneously, those
will be killed also.

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

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
