    CPU usage rises to 90% without reason on my Mac Mountain Lion

    I have upgraded my Mac to Mountain Lion 10.8.4 and recently started to get the CPU usage problem where it rises upto 90% without any reason which means I have no applications opened but still it raises to that level. What is the reason for it? How to resolve this now?

    Hello friend,


    I have the solution for your problem just do as i say................................

    1.This can be the problem of the hardware only.

    2.I do not think that this is the software problem.

    3.However you try to Restore your Mac using Time Machine.

    4.If still you have the problem Then it is the hardware problem.

    5.So take it to the near by Apple Store and get it repaired.

    All the best...............................

    Dear Friend...

    It is not just because you don't have applications, sometimes there are some other reasons due to which the such problems arise.

    1. Anti-Virus Issue
    2. OS Issue
    3. Hardware issue

    Solution:-

    1. You need to check that what kind of applications running in your background of your Mac OS because sometimes anti-virus also can be a reason for the same.
    If it is running in your background and taking very much power, then uninstall it and install any lighter and compatible version.

    2. Sometimes the charger is also another reason due to which it heat up your device and then it increases your CPU power.
    So this is completely a hardware issue which must be sort at Apple Care Centre.

    Thank you...
