Hi, I am new to Apple and I have an iMac 27 2.7 GHz intel i5 with 16 gb of RAM and a 1 TB hard drive.  Do I need to clean the hard drive and defragment it as I used to with my windows based machines?


It seems to freeze and slow down occasionally and sometimes doesnt shut down.

iMac, OS X Mountain Lion (10.8.2)

    Under Mac OS X defragmentation doesn't need to be done, as far as i can remember Mac OS X does this to a degree by itself.


    when you say 'cleaning', emptying the trash, clearing the browser cache and things like that will speed up your Mac.


    Just try to not have too many apps and whatnot open at once and it shouldn't freeze or slow down.


    Hope that helps.

    What are you doing when this happens?


    For your sake do not try using ANY aftermarket "clean my mac" crap. It will do nothing but cause problems, some of which are hard to fix.

    Thanks guys, thats what I was hoping and part of the reason I moved to Apple.  It is probably too many apps open at once.  Will take your advice and def not purchase any aftermarket programs.  Thanks again.

    You might try watching RAM with Activity Monitor to see if you are using a lot of virtual memory.
