I have a 4GB mac book pro...cant figure out what is causing my mac book pro disc usage to be so high....I mainly use it for music with only 8000 songs on itunes.....not able to see what is filling up my computer....can anyone please help?
Okay, let's start at the beginning.
There's no such thing as a 4GB MacBook Pro. You are confusing RAM with STORAGE. They are two entirely different things.
How big is your hard drive, and how much free space is left?
"Only" 8000 songs? That's actually quite a lot. What format are they in?
You can try downloading the free Grand Perspective which should quickly show you the culprit. My guess is its your iTunes library.
You're asking for a hard drive crash at this point. Am "assuming" you also do not have a backup?
Not incompetence in downloading and nope, not shocked either. You don't have enough space left on your hard drive to put much of anything. While you may have over 1 GB of free space in total, it's highly unlikely that you have anything but very small bits of contiguous free space on that drive. And your system has probably been using 100% of that for virtual memory. Will be just totally amazed if you have not been experiencing the dreaded spinning beach ball for awhile while trying to use that system to do just about anything.
First thing you need to do is free up some space. You should never have less than 15% free space available on any drive or partition that has your booting operating system on it. On that system, that means at least 35-40GB free space. I keep my system drives at 25-30% free space minimum.
If you don't have a backup, as soon as you can free enough space to run a backup, I'd suggest you do it.
And if you plan on keeping that much data on your system drive, it's way past the time for you to upgrade to a larger drive.
8000 songs is a lot songs and if you didn't turn off the duplicate option in iTunes it means you have twice as many songs. In iTunes go to your preferences in the menu and in the advanced tab uncheck copy files if you don't want duplicates of your songs.
