Changed Administrator permission to (Read-only), now the system doesnt boot
I need your brains to help me with the following problem:
By not knowing, I have changed Administrator permission on my iMAC to "read-only"
Another user account I always use stayed as "read & write"
BUT, after that system will not boot.
I tried to run Disk Utility, and Disk Repair (repairing permissions were done too I think, because the button was inactive)
Tried to reboot, still the same gray screen... 😟
What other options do I have to restore admin permissions? that is the cause of a problem, right?
iMac, Mac OS X (10.5)
