    John Galt is correct about OS extensions and lots of applications and utilities from various sources. Afte huge (I mean HUGE) problems with my iMac (2011), the Apple Centre thought that corruprion had occurred randomyl, and that the several (not very many) apps and itilities that I ran had contributed. An erase and installation of Mountain Lion has helped (but I still get mouse problems).

     

    I am now very careful indeed about running an application or utility downloaded from somewhere unknown, and I especially avoid OS extensions except from thoroughly reliable sources. (SnapZPro is the only extension that I have.)

    You've gotten great suggestions from the others; doing some "housecleaning" may take care of the problem; if still necessary, adding RAM will also help.

    I also agree the community has done a stellar job in delivering assistance. I know I have lots of 3rd party apps. I do a lot of graphics and photography work and the ones I'm likely to keep involve these two sectors. I've uninstalled MacKeeper and Log Me In, and tonight will add another 8 GB of RAM, which brings up another question: I live in a small community and the RAM I am adding is slightly less than the 1333MHz Apple states I should use. The computer guy says it will still work in my iMac and I shouldn't really notice any appreciable speed from the 1333MHz. The Apple guide says to ONLY use the parameters they have outlined which, of course, includes the 1333MHz. Any guidance here on that?

     

    Also, I'm going to go through and begin eliminating many of those apps I rarely or never use.

     

    Thanks all for your assistance. You guys are the best.

    Ah, no.

     

    Use only the correct RAM for your computer. Faster is not correct. Slower is not correct. Your computer guy is guaranteeing himself a return visit with such astonishingly bad advice.

     

    Purchase RAM from a reliable vendor. OWC a/k/a MacSales and Crucial are two reliable vendors.

    Not true...

     

    You can use this Link to check which RAM is suitable for your Mac...

    It is Important to get the Correct and Matching RAM

     

    For best performance, fill all memory slots, installing an equal memory module in each slot.

     

    That site also has videos on how to Install RAM should you need it...

    Thanks again, folks, for helping me out.

     

    I'm going to order from the OWE link above. I did read the part about equal memory for each slot. Will it harm the computer to have 2 x 2 GB  and 2x4 in the other two?


    What sort of harm?

  • AnaMusic Level 9 Level 9 (57,075 points)

    No harm as such... But... Apples recommendation is...

     

    For best performance, fill all memory slots, installing an equal memory module in each slot.

    I've been running my iMacs for about 2 years with 2 x 2 GB in two slots and 2 x 4 GB in the other two = total of 12 GB. Make sure yours looks like this once installed - matching the RAM horizontally (in other words, just leave the 2 x 2 you have where they are at and install the other two in the two empty slots):
