what does free up disk space mean on a mac computer? I'm trying to play my sims game?

Answer 1

When your computer's memory fills up you are unable to play certain games that require memory. There is no really easy solution to this. You can upgrade your computer by adding new memory, or try to compress the memory in your hard drive. Good luck.

Answer 2

Has your sims game filled up all your disk space? If so, I guess freeing up disk space would delete stuff you no longer use in order for you to play your game.
