I know that back in the day, when I used Windows computers, they always said that you should have at least 10% of your hard drive free, and that less could affect the performance of your computer. Is this true for macs?
Thanks guys, that's some good information. One thing I've noticed lately is the DVD Player program crashing, a lot. It always happens when the DVD starts playing. Is the lack of hard drive space a possible cause of that? Or is this totally unconnected?
If the drive is 100% full, then it can't create a swap file which might cause crashes etc. Try another player, VLC for example
