Uncommanded Restarts Eventually Leading to No Complete BootAbout a month ago my mid-2011 i5 Mac Mini started performing uncommanded restarts. Specs: 16gb RAM, original 500gb HDD in...
Rispondi a "Mac keeps restarting for no clear reason."Sorry, but I think Jon Price nailed it in a previous comment. Apple engineered an expiration date into the mid-2011 Mac Mini, triggered by their latest 'free' OS upgrades. There have been far too many people chasing the same issue, trying the same solutions, ending up with the same result. Apple hardware over five years old (cpu's or phones) cannot be trusted. After 25+ years of being an Apple fanboy, I'm over them. Now a committed Windoze user (hate the software, but the hardware is solid).
Rispondi a "Random power failure even after several attempts to rectify."I'm having the very same problem. l've run the built-in diagnostics numerous times, passing every time. lt will boot to diagnostics or recovery and stay up for DAYS!!! But when I boot from either drive, I get a endless loop of un-commanded restarts!
Rispondi a "Mac Mini, Late 2012 2.5 GHz i5, 820-3227-A Power Problem, Shuts Down"Did you ever get resolution to this? I am in a similar situation. About a month ago my mid-2011 i5 Mac Mini started performing uncommanded restarts. Specs: 16gb RAM, original 500gb HDD in the primary position (thermal sensor intact), 500gb SSD in the secondary bay. At first the restart frequency was every 30 minutes to an hour. In time, the frequency increased - but I could get it to stay up for extended periods by running certain apps in the foreground. Eventually it got to the point that the frequency of restarts were so great that it became unusable. And finally, it would not even finish booting. In an effort to solve the issue, I: 1. replaced the fan. (it was getting noisy and obviously failing) 2. Replaced the power supply. (thinking the failing fan had over stressed and damaged it) 3. tested individual RAM sticks by inserted them, one at a time, into different banks. 4. Pulled the fan and shroud to access the drive connectors. Disconnected the SSD. No Joy. 5. Reconnected the SSD, disconnected the...
