    Hello all, im fairly new to macs. I have a 21.5" i5 2011 imac running mountain lion. Recently, my computer has been going through these cycles where most all trackpad gestures stop working and whenever I type it is in this random wingdings symbol looking font. Also, other things have stopped responding like the computer and display sleep sliders in the energy saver settings. they wont move if i try to drag them. Usually a few hours later it will work fine, but now it has been this way for a while. Very frustrating, and when it is in this crazy mode I can't do anything not being able to type (restarting, shutting down, etc.). Any ideas? Thanks

    The only thing I can really think of is to reset the System Management Controller.

    Follow Apple's support document for that and select "Resetting the SMC for Mac Pro, Intel-based iMac, Intel-based Mac mini, or Intel-based Xserve" because you have a recent 21.5" iMac.

    Hope this helps. If this doesn't work you could always ask or take your iMac into an Apple Genius Bar.
