Eh, I have to calm down after these odd issues. This was a new one for me though.
Kind of started overnight, I put my older iMac to sleep, but it restarted by itself about 90 min later (it's done this before, random times). I'll get up, wait until the desktop appears, icons load, then shut it down. But doing that last night, the CPU didn't shut down...just a black dim lit screen that hung there. I had to manually hit power in the back to turn it off. I hate doing that..I had no other option.
This morning, I hit power...walked away to get coffee, come back to a plain white screen - no Apple logo, nothing.
(Insert panic feelings, and I'm not even 1/2 awake yet!)
Shift+Power, CMD+R..no response.
PRAM / SMC resetting...nothing.
One site I did find...THANK GOD - and perhaps this is not news to many, it was to me though.
Disconnect all USB devices from the iMac, try and restart again. That did it.
In fact, this was the fastest this Mac has booted up in a long time with the SSD I put in last Summer.
(I have a 4TB and a 2TB drive connected to this), I have a feeling this older 2TB is causing big issues for some odd reason, it was acting funky about 3 weeks ago, I reformatted it. After plugging this back into the USB, it took 2-3 minutes for the drive to even show up on the desktop, not normal.
So..big sigh of relief for now. Just very happy this wasn;t the main hard drive going dead!
If anyone has this kind of trouble....try unplugging everything from the rear of the Mac - all USB, all external hard drives.
Try a restart again. See what happens.
