Save 6-7 GB on Leopard

If you have a MacBook Air, this tip is especially helpful, given the tiny size of your hard drive.

Here are some quick steps you can follow to save 6-7 GB:

1. Open up terminal and type "rm -r /Library/Printers/*" to delete 3GB worth of printer drivers. Then use the Leopard install CD to reinstall drivers for the 1-2 printers you actually own.

2. Disable safe sleep and remove the sleeimage. To do this, open your terminal and type "sudo pmset -a hibernatemode 0; sudo rm /var/vm/sleepimage"

Note: After you do this your mac will take about 3 seconds to go to sleep, as opposed to ~15. However, if your battery is exhausted while the mac is sleeping, you will loose your session data.

To re-enable safe sleep, open your terminal and type "sudo pmset -a hibernatemode 0"

3. Delete your iWork '08 trial (if you're not using it):

Drag the iWork folder (in Applications) to the trash can.

You'll also want to delete:
library > receipts > iwork08trial.pkg
library > preferences > com.apple.iwork08.plist
youraccount > library > preferences > com.apple.iWork.Keynote.plist
youraccount > library > preferences > com.apple.iWork.Numbers.plist
youraccount > library > preferences > com.apple.iWork.Pages.plist
