do i need to clean my imac?
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)
