    I just got myself a new iMac 27 (680mx, 16gb ram, 768gb SSD), and I'm very happy with the machine. However, there is one annoying issue. I have the latest version of Mountain Lion, and after a few days the mdworker process started to hang several times a day, getting stuck at 100%. The only way to stop this is to boot OSX in safe mode.

    Is there any way to permanently fix this issue?
    When I go through the mdworker error messages in Console, I get these messages A LOT every day:

    (There are several others, but these are the most frequent ones I see in my Console right now.)

    I would really appreciate any help, I'm completely stuck here. :confused:
