Eeek. I hosed my Mac during a firmware update...the folks at the Apple store were great...I didn't lose anything...the tech made a copy of the entire HD to my external drive and I just had to copy over my files to the MacBook. Still scary.

Rules:

1. Backup hourly.
2. See Rule 1.

Also, what the tech did, you could probably do yourself if you got the steps and watched him in detail.

I've had more problems with PCs than with Macs....much of which I attribute to Microsquish and some of their resource-hogging apps.

MS Outlook...the world's only virus with a GUI.
