Oh, wow. That's weird. I can't eject disks in my MacBook via the keyboard button until I'm in OS X. Or so I thought. I'll have to try it later.
Anyway, repairing disk permissions is always a good thing to do often when you have problems with your Mac. In most cases you won't need to boot off the DVD though. You can find the Disk Utility in your Utilities folder in your Applications folder.
Repairing the disk will find and fix any problems on your hard drive.
Please report back to let me know if it fixed the problem or not!
how long should the permission repair take? Its been about 10 minutes and it hasn't finished.
Thanks
