Installed Apple Recovery Disc in iMac, but despite the “full” bar does NOT progress.
I have an mid 2011 iMac A1311 21.5 that up till 2 days ago was running fine, until I got a split screen, with no other option to “X” out other than to shut it down. This happened twice. On the third time of rebooting, it got stuck in a loop, where the Apple progress bar would get to 50%, then the unit would shut down and start up again. I can NOT get into recovery mode, or safe mode, or reinstall over WiFi. I finally installed the original CD Apple disc 2 into the DVD and pressed c. I am now STUCK with a full progress bar for the last 1 1/2 hours. The left back corner gets much hotter than the right side. I did run a ‘Hardware diagnostics’ with NO errors. I was running High Sierra on it. I tried making a bootable USB drive using my other iMac 2013 running Catalina, but it won’t let me get the download off the Apple site. Any suggestions where to go from here??
