Trash their contents (although I find both rather useful, so YMMV).

Read into which directories are excluded by default from Time Machine (you don't see them in the preference pane!), I am pretty sure Logs and Caches are among them. Now we're getting very much into subjective territory: Use Disk Inventory X (free) or DaisyDisk (non-free but pretty) to look around your whole disk to see where your storage went. There is no '100%' solution, and since you keep on installing/trying/uninstalling there's really no point.Ĭheck the LaunchAgents and LaunchDaemons directories within your user library and the /Library, as well as the Accounts preference pane in System Preferences.app for unnecessary Login Items

Use a tool like Disk Inventory X or DaisyDisk, point it at ~/Library/Application Support and nuke anything with more that X MB (I'd recommend 10) you don't recognize or no longer use.

Keep the files around another month in case you start an application and have an unexpected first-launch experience. Simply start any application once you install. Anything unused in the last X weeks/months can go. Go to ~/Library/Preferences/ and sort by modification date.
