Uninstaller question

[Graham Samuel]

I’m developing a very simple uninstaller for a Mac app. I have an installer, thanks to DropDMG. 

The uninstallation process isn’t difficult - it’s just a matter of deleting all the involved files (some are slightly tricky to find, like dock aliases, but I guess there’s a way around that). But there’s one issue that I’m unsure about: what to do if the user has not obeyed the installer's instructions to place the app in the Applications folder, or has maybe got a beta copy that wasn’t installed using the installer, or has made a ‘spare’ copy somewhere on their hard disk which I don’t know about. I can’t see any way to detect these ‘rogue’ copies - can anyone else think of one? I know there are some big hitters in this area like CleanMyMac that claim to be able to find everything to do with an installed app, but I am not that ambitious - I just don’t want to miss anything obvious.

Any help would be appreciated.

PS When I crack this, I’ll have to do the same thing for a PC version of the app. But first things first.
