Q: I have an iMac 24" system. I just recently installed MAC OS X 10.7.4 (Lion) on my system. Since doing so, my system consistently hangs. Particularly when using iMovie and iPhoto.

I have an iMac 24" system. I just recently installed MAC OS X 10.7.4 (Lion) on my system. Since doing so, my system consistently hangs. Particularly when using iMovie and iPhoto. I have to power off my system to get it running again. Any suggestions on what I can do  to address this situation.

    I would first reset the SMC:

    • Shut down and unplug the Mac.
    • Keep the Mac unplugged for at least fifteen seconds.
    • Plug the Mac back in and do not turn it back on for at least five seconds.
    • Press the power button to turn the Mac back on.

     

    Then I would reset the PRAM by rebooting the iMac while simultaneously holding the Command-Option-P-R keys until the machine restarts a second time.

     

    Let us know if these  procedures don't solve the problems.

     

    Hope this helps
