Hi guys, I'm using a Wacom tablet on my MacBook Pro, but it has started to malfunction. A person from Wacom told me to "repair your hard disk permissions using your Disk Utility (in your Utilities folder)" How do I do this? Is it safe? Do I need any CDs (my MacOS CD for example..)? Will it delete everything in my Mac? Btw, I use Leopard version 10.6.4 Thanks in advance!
