Back in the days of Mac Classic OS all that was needed to dispose of an app that was no longer used was a quick drag and drop to the Trash can. Macs with OS X are based on Unix and apps tend to scatter their support files and preferences here and there. Here are ways to trash the apps.
Where’s The Uninstaller?
For whatever reason that Apple doesn’t want to release to the public, the Mac doesn’t come with a built-in installer or uninstaller.
That means apps get installed a number of different ways (from a formal installer app to a simple drag and drop).
The trick to uninstalling an app you don’t want any longer is for the uninstaller (a nice name than trash app) to know where all the app’s support files are located.
Apps like TrashMe do a good job tracking down those often wayward files, configurations, and preferences, and sending them on their way to the trash.
TrashMe does more than just send apps and their related files to the Trash. It also handles removal of Dashboard Widgets, Plugins, and System Preference Panes. Settings make it easy to prevent selected apps from being deleted accidentally.
Just drag and drop to TrashMe the app you want to delete from your Mac.
Once you’ve dragged and dropped (the app you wanted to delete) you’ll get a list of the apps and files TrashMe thinks should be deleted. Check off those files you’re certain you won’t miss, and the deed gets done.
TrashMe can also clean up and trash the files present in a few Mac caches, force empty your Trash can (in case you get a stubborn permissions issue that won’t let you delete a file), and, as a side bonus that’s totally unnecessary, manage a list of your favorite third party apps.
