Question

How do I uninstall plus-ins from Aperture 3?

Answer 1

So you are using OS 10.7.2?
You have two options: You can reveal the folders permanently from the Terminal:
Start the Terminal.app from Applications -> Utilities, then enter:
      sudo  chflags nohidden /Library; open /Library               press return
to make the System Library visible and to reveal it in the Finder,
and
       chflags nohidden ~/Library; open ~/Library        
to make the User Library visible and to reveal it in the Finder.
The "sudo" prefix makes you do the command authorized as Administrator. You will have to enter your admin password. Be careful when using this. Read any command twice to be sure you do not enter any wrong commands.
If you want to leave the libraries hidden,and only open them in the Finder, use the Finder "Go" menu.
To show the User Library:
Finder menu -> Go     hold down the opt-key, till the Library appears in the drop down menu, select it
To show the System Library:
Finder menu -> Go  -> Go to Folder
enter      /Library        press return.
To hide the libraries again, if you prefer this, enter
     chflags hidden ~/Library
and
     chflags hidden /Library
in the Terminal window.
Good Luck     and Happy New Year!
