I have the new imac 2012 for only two weeks. Now it won't shut down and is frozen with the rainbow spinning wheel. What do I do? Should I return the Mac?

    i don't think that there's a need to return it.

    more probable is an issue in mountain lion...


    to check this, your first step should be to install a maintenance tool - "Onyx" recommended.

    it's free and removes useless data (log files, temp files, caches, ...) from your hard drive and

    also performs some maintenance scripts.


    download it, install it, start it, let it check the SMART status (takes few seconds), enter your password, switch to "maintenance" tab, select "rebuild", enable all check boxes, hit "start", wait,

    switch to "automation" tab, enable all check boxes, hit "start", wait, let Ony restart your machine.


    in case of stuck, switch it off by holding power button and restart it manually.

    after onyx ran, the boot and logon could take a few minutes - so don't worry.


    after this procedure, your problems may be solved.


    you can run onxy with this settings once a month to keep your system "clean" ...


    hope this helped...?!

    u can use the shortcut keys to shut it down.

    ctrl+alt+cmd+eject button.

    or maybe u can try to delete all the running apps to clear memory:this can be done by opening force quit frm finder. shortcut keys:alt+cmd+esc

    hope this helped u

    I would agree that you shouldn't return it. The hardware is probably not the problem. However, If you are uncomfortable with doing some troubleshooting and repair of the software, then perhaps the easiest thing would be to take it back to the store and let the "geniuses" do it for you.

    Macs usually work quite well, but computers and software are not perfect, and sometimes an error occurrs which must be fixed. Your mac has some built in repair software that you should probably try first before resorting to any third party software. Onyx is good, but you probably don't need it.

    Here's what I would do:

    1. Press and hold the power button to shut the computer down.

    2. restart in Recovery mode and repair your hard disk: here are some directions: When to Run First Aid in Mountain Lion's Disk Utility - For Dummies

    3. After the disk repair, repair permissions too. Those buttons are on the left side of the disk utility window.

    4. make sure your hard disk is not too full. It needs to be maybe 20% empty to function properly, maybe more if you do some very memory intensive projects, like edit video or photoshop.

    good advice.

    the last step, before returning it, should be Onyx.

  prevent your mac from being away ^^
