    Angry Mac mini 2011 problem
    Hi guys im having a problem with my mini. Ive had it in with the apple store guys and they cant find any problem they swapped out my hardrive in case it was that but still its giving me problems.

    Its freezing the screen but still it runs in the back ground,pointer keeps moving but nothing can be selected,sometimes it restarts but most of the time i have to hard restart it

    Its a 2.7 i7 16gb ram
    running 10.8.2

    If you can help it would be great cause I'm getting nowhere with my apple store and i cant figure out what is causing it

    This came up earlier when it restarted

    Bad times

    It looks like it might be a memory fault but it could also be something else. Try starting your Mini in safe mode and let it run that way for awhile to see if the freezing occurs. Hold down your shift key as soon as you hear the boot sound and continue holding it until the machine boots up. Running in safe mode removes all third party drivers and all startup items. It also removes the sound driver.

    Thanks for the speedy reply buddy! Ill give that a go.

    When you say memory problem do you mean the ram could be the problem?

    Yes, it appears to be faulting according to the kernel panic report you posted. But sometimes that's deceptive and could be caused by something else. That's why we have to run the machine in safe mode for awhile to see if the same problem occurs.

    Further if the kernel panics persist, try running Apple Hardware Test over the mini≥ Use extended mode which checks out memory, graphics, logic board etc.

    Hang on to those original install discs like grim death! Using OS X.7 or later make a bootable USB thumb drive before running Installer!

    If it froze in Safe mode it's definitely a hardware problem. The first thing I would try is swap out the memory modules. You can try removing them one module at a time and see if it freezes. You could also have a failing hard drive that is freezing. Sometimes tests like the Apple Hardware test are not definitive enough to pinpoint the problem.

    Ive a new hardrive that the apple store fitted just in case. But i do have third party ram so that could be the problem if you say it might be ram. Do you guys recommend any ram? Ive 16gb in it at the moment that i bought from an ebay store.

    We recommend memory from either Crucial or Other World Computing. I usually tell folks to avoid buying memory from eBay sellers. Some eBay sellers are legitimate good retailers while others not so. Sometimes they'll sell memory designed for PCs as OK for the Mac while it's not.

    Had the crucial ram installed for 2 days now and it hasn't froze once,so seems like its fixed!

    Mac-forums especially chscag you guys rock! Apple couldn't even fix my mini or say "hey that ram is rubbish get it changed"

    Thanks so much! Im now enjoying using my mini again.
