Aaron is a boy Level 1 (0 points)


I am currently running Mountaint Lion 10.8.5 (haven't updated to mavericks quite yet) on a 2.53 GHz Intel core 2 duo Macbook Pro.  I'm not sure of the year it was made but if that's really important I can look up the serial.  Anyways, this thing is making me crazy.  Kernel Panics ("your computer shut down because of a problem") have become an extraordinarily common part of my life.  The more demanding the task (LOW resolution games would be the most demanding), the more frequent the Panics. Sometimes it even happens when I'm just browsing or watching netflix.  Usually before the kernel panic occurs the computer has heated up quite a bit and the fan starts wurring like an engine.  I do consistently use my laptop on my bed; I heard that may be affecting the airflow to the vents.  But I assure you the Panics occur on flat surfaces as well.  I bought this machine used so I don't know it's full history, but under my care, it has taken no spills, drops, or damages otherwise.  I have tried many things to help: Repairing my hard drive with Disk Utility, resetting my PRAM, cleaning things up with MacKeeper, even global virus scans that come up clean.  I don't claim to be any kind of expert, but I have tried all the tools at the disposal of my knowledge and I am really starting to get frustrated.

My last OS update was recent; far after panics started to be a problem.

I pray to god this is not a hardware issue.


Any help would be of the highest appreciation

PS I don't know if anyone could help with this, but my machine also runs unbelievably slow considering it has 8 whopping Gigabytes of RAM.

    this problem is probably being caused by your RAM; you have a Mid 2009 model, which requires 1066 MHz RAM, but you currently have 1333 MHz RAM installed.

    great! how do i go about that? should I replace my 4G chips with 2Gs?  I sincerely hope that doesn't make even slower


  • Melophage Level 5 (7,130 points)

    Aaron is a boy,


    you can replace your two 4 GB 1333 MHz memory modules with two 4 GB 1066 MHz memory modules, so that you can continue to have a total of 8 GB of RAM installed. Having the proper speed RAM installed in your MacBook Pro will make a world of difference compared to its current performance. The little white booklet that originally came in the box with your MacBook Pro shows how to replace the memory modules, if you’re comfortable with performing minor upgrades; the important thing is to discharge any static electricity on you by touching something metallic before handling the memory modules or touching anything inside of your MacBook Pro. If you’d be more comfortable with someone else doing the memory module installation, then any competent computer shop would be able to do it.
