I needed to delete/uninstall an application that was running. It was screen saver app that ran over the regular screen saver, and I hated it. I downloaded it from the App Store, and do not suspect malware. It was just an awful, inexpensive app. When I tried to delete/uninstall it, I got a warning message that said I could not delete a running program. But it also gave me a link to where I could over-ride that, I think, within System Preferences. I clicked a checkbox that would "allow deletion of running applications." After checking that box, I was able to delete the offending application.
I would like to go back to that setting and uncheck "allow deletion of running applications," but I can't find it in any of the System Preferences or other Utilities. A quick internet search revealed nothing. Maybe I'm using the wrong terms?
Is anyone aware of this setting and where it might be located?
