I was crusing a Mac Users forum the other day, and fond this software that can help you regain some of your hard drive space.
It's called Monolingual, and it removes all of the bazillion different language versions of your installed software that you probably don't use, like Ajerbajani or Farsi and a bunch more. Just download the software (it's free!) and check off the boxes of the languages that you aren't fluent in :-) then press enter.
I have a lot of software on my Mac, so mine took about eight minutes to run, but it cleared - get this - FIVE and a half GB of memory on my hard drive! That's a lot of space for photos and music, people!
