I may have made a mistake. I was attempting to lock down security on our hard drives and accidentally set the permissions for the group "Everyone" on the highest level hard drive to "No Access." I know, I know...
So, now I can't log in, all I get is grey Apple screen and then progress stops. My assumption is that this is because there is no access to the hard drive.
If my assumption is correct, is there any way to undo/correct this?
I have tried the following:
1. Booting from OS X Snow Leopard disk - will not boot 2. Booting into Target Disk mode and mounting as a FireWire drive on another system - did not mount.
Does anyone have a better tip or better recommendation beyond being more careful in the future?
