UPDATE: The bott issue came from the memory (16GB@1600MHz, Corsair). Factory RAM works boots fine.
Hi,
Sorry for my english. It's not my native lang.
for a few days my Mac Mini (late 2012, 2.6GHz quad, 1080 hdmi display) ran fine. First I got a snowy screen (thought it came from my acer display). Then I got random black screens. Today the Mini can't shut down! If I choose "Shut Down" in ML, it first quits the OS normally and turns itself of (fan... etc.). After 2 seconds it starts again and boots.
(This behaviour is different from the normal reboot command, where the fan keeps running)
This behaviour is getting more strange. Now when I turn on the Mini it turns it self 2-5 times on and off and then boots.
I already unplugged all unnecessary devices. Only HDMI, USB (Apple Keyboard, Mouse) and power is plugged.
I tried this RAM reset: http://support.apple.com/kb/HT1379?viewlocale=de_DE
It is possible that the display issues are software bugs. However, I think it is possible too that the display issues are hardware problems, if you associate it with my boot issues.
Anyone else has experienced a strange boot behaviour?
Thanks very much
Best regards
