Hello! I tried installing Sims 3 on my MBP but for some reason it stops at 569 out of 600 files so I force quitted and tried again and got the same results and force quitted subsequently too. I did that about 4 times. Sims 3 would put about 6 GB on your HD and I found out afterwards I had about 24 GB missing after that attempted installs. How can I remove that 24 GB? Running Snow Leopard btw.
