My late 2012 pro with retina is going dead temporarily. If I am playing music (usually on youtube), it stops, the screen goes black, fans aren't running, and there is no sign of life. Pushing keys or pad, including power key brings no response. Same with holding power key. But then everything comes back on. Happening maybe a couple of times a day. At first it would stay blacked out from 10 to 30 seconds. Sometimes that's lengthening now to 20 minutes or more. Then you most often need to push power to start up but the short times may only need a key pressed to be back in business.
The unit has had some issues. Couple of years ago the logic board needed replacing, then the battery and SSD. I couldn't afford Apple's prices, so these were done with after market help. The unit runs warmer than it should but not real hot. I cleaned the fans up (I'm a watch technician, so used to taking things apart) but it didn't make much difference. so I installed SMC fan controller.
Before the blackouts, I was having signs of possible malware so did a clean install. First I installed High Sierra so I could continue to use Office for Mac 2011. The blackouts were getting worse so I tried upgrading to Catalina two days ago — made no difference. Since then upgrade programs are freezing up more often. I just started up the next day after a long black out and Firefox, Music, and App Store were all frozen upon opening. Several minutes wait enabled closing them.
Anyone tell me what is going on?
