    Hi there, i'm having some problems with my Mac in the last 2/3 months with it running really slow and laggy. Also, every now and then it freezes, the wheel spins in the middle and eventually turns itself off. Can anyone suggest anything? The Mac is around 2/2.5 years old and have had no previous problems with it. Thanks in advance.

    Thanks, i've followed most of the steps although most didn't need doing. I'll see how it is for a few days. Thanks.

    If you run into problems again, post screenshots of the CPU tab in Activity Monitor at the time you're having the problem.

    Try a simple re-install of the OS. You don't need to wipe the hard drive, just do a cmd-r and select re-install OSX. Doesn't take long and sometimes that clears issues that can cause the problems you are having. All of your data will still be there.

    What he meant was, does it have a mechanical harddrive or an SSD?

    Given the storage size, I'll assume it's a spinning HDD.

    Your HDD could very well be on its way out.

    You can replace it with a new one, but if I were you, I'd buy an SSD and give it a massive performance boost (boot time of 11 seconds, for instance, plus instant app launching).

    It's the 27 inch model from 2011 if that helps, sorry my knowledge goes no further! Would you suggest the SSD then as i use it every day for work and need it?! Thanks for your help

    I'd highly recommend it.

    Since it's a 2011 model, it has Thunderbolt ports. If you're not comfortable with opening the iMac up, I'd suggest you to buy an external Thunderbolt SSD.

    True but they are still too expensive for most people.

    No, SSDs are affordable to everyone already.

    250GB Samsung 840 Evos are pretty cheap, fast and good.

    They are small especially for the money. That is a major problem for those who require large amounts of space. Externals are not the answer for everyone.

    HDDs used to be about just as pricey in the early days.

    It's considered cheap already, and the performance benefits are totally worth it.

    Thanks for the feedback guys. I don't require much space but i have software running which probably slows the Mac down. Is it worth taking it to the Apple store first?

    if you haven't done so already, then use Disk Utility to verify disk and repair permissions. After that, if it's still an issue and you're not confident to replace drives, then take it to a store.

    I've verified the disk - 'Macintosh HD appears to be ok'. Then repaired the permissions and was prompted with persmissions repair complete. Will see how it is the next few days. Just out of curiousity, i am using Google Chrome and this seems to be particularly slow at times aswell?

    There have been many reports of performance issues with Chrome. Many have uninstalled it for those reasons.
