Rev A/B iMac Freezes on Startup
« on: Yesterday at 12:39:48 PM »
Hello folks, last night I started up my turquoise iMac, twice, and both times it froze before extensions started loading up. I've attached a screen capture.

I know someone in my area who might be able to do something about it, but he just rose my IIcx from its coma, free of charge, so I figured I'd ask here to see if this might be a simple fix.

Thank you guys.

Reset PRAM. Hold the keys for a few seconds after turning on the Mac before rebooting -- Control + CMD + F + O
Boot Mac OS without extensions -- Hold Shift.

If this does not help, you can try to boot from the CD, for example, the OS9 image prepared by the community is perfect for this.

Question (it's been a long time since I last did this): Do press Control + CMD + F + O before or after the opening chime? And, what about the shift key for extensions?

Thanks.
