    Only if the iMac meets the system requirements for the OS version in question.

    To find out info about your system,

    Click on the Apple symbol in the upper left of the OS X main menu bar. A drop down menu appears.

    Click About this Mac. A smaller popup window appears. This gives you basic info like what version of OS X your iMac is running, the speed of your iMac's CPU and how much RAM is installed.

    Click on the button that says More Info. A larger window appears giving you a complete overview of your iMac's hardware specs.

    Highlight all of this info and copy/paste all of this into another reply to this post, editing out your iMac's serial number before actually posting the reply.

    This will tell us everything about your iMac so we may begin to help with your iMac issues.


    In the meantime.
