Tried open firmware password reset shown here & doesn't work, ideas?
The answer here was under "How do I reset the open firmware password on my Mac?"
I think I've done exactly as the instructions said, but maybe I missed a step?
I have pulled the easy to access RAM from the base of the iMac and zapped the PRAM, but can't get past the lock and arrow icons. The Command-Option-PR PRAM set doesn't do anything - no chimes as is usual. Clicking the Option key thereafter just takes me back to the dreaded lock and arrow. I mistakenly set my startup to NetBoot and now can't get it back to restart from the hard drive... help! The CD drive isn't working correctly either so holding down the D key doesn't get me anywhere either.
Cette question est-elle utile ?
