Mac Mini auto restarts when shutting down with Mountain Lion

problem not yet solved with 10.8.2 ... I was thinking to contact apple...

I fixed the problem by changing the display in System Preferences. I have 3 HDMI ports. The first one seems to display everything in 1300 something by 800 something (I forget exact dimensions). But HDMI2 and HDMI3 display things in 1920x1080. Not sure if this has anything to do with it, but.....

I changed the display to 1600x900 and it shuts down flawlessly now. Just my two cents.

Any progress?

What do you guys do? Change the resolution every time you shut down?

I have a 720p telly and this is a ****** problem.. 😟

1080p&i shuts down properly...

Yeah I always do the same...changing resolution before shutting down,and it works.

Hope Apple fixes this sooner or later...

Same problem for me, iMac with 10.8.2!

my 2012 ML mini only restarts if i let apps auto quit at shutdown. if i manually quit each open app before shutdown no restart. annoying.. come on apple fix please..............

Do you use 720p setting??

Ok, this worked for me: I use a Samsung TV as a monitor. I tried to switch the HDMI cable from HDMI2 to HDMI1, then changed the resolution to 1600x900...and it works! This way, I don't have to change resolution every time, before shutting down. Not the ideal resolution as well (1360x768 should be the optimum for my monitor), but still suitable for a clear vision. Just wanted to share with you, hope this helps. And sorry for my English 😉

The guys that were saying that 1080p works were correct.

Mine had change somehow I then reset it to 1080 and now it shuts down properly. I now need Binoculars when Im browsing!!!!

anyone know if apple sells them as an accessory to the macmini?

LOL

So I have been struggling with this issue as well for a few weeks. My mac mini server is connected to an LG HDTV as well. Force shutdown is a bad idea. Looks like, as described in earlier posts, when I change the resolution away from 1360 x 768 to 1600 x 900, the problem goes away.

Since there is no permanant fix for this, and it turns out to be a hardware issue that would need to be replaced, are we expected to pay for the replacement after apple care warranty is over? How can I get the problem on record to show that their is no fix for this during the time I am covered and should not have to pay for any repair once it is over?

Thanks.

Well it seems to be a realy stupid macmini problem and I have no idea if apple can sort it out with a software update. lets hope so

Well so far so good for me,

I've recently bought a new tv, a full hd Samsung all singing all dancing effort and my Mac mini has shut down twice, yes you read it TWICE!!! Without incident so far,

I'm obviously going to see how it goes but, I just wanted to update you guys.

Still got my fingers crossed for a better cheaper solution though

Just switched my resolution to 1600x900 and it seems to work for me as well. One successful shutdown under my belt so far...
