I just installed version 1.0 of the iMac SMC Firmware Update on my Intel iMac.
This process involves quitting all apps and restarting the computer. At restart, the machine briefly makes a sound unlike anything I've every heard from a Mac...sort of like a fan running, or a Roomba. It's accompanied by an animated graphic of a white bar turning gray.
Could it, in fact, have been the iMac's fan? The utility doing the updating might have been checking components or something.ReplyDelete
Then again, maybe your desk is now cleaner!
Welcome to the world of Windows. I hear that all the time on my upgrades.ReplyDelete
Just kidding, of course; I have no idea.
Was not able to make it to the Meetup this month. Hope to see you there next time.
