2008 iMac was getting increasingly slow. No problems diagnosed—it was just getting old, taking ages to open applications—and driving me nuts. I was nervous about putting an SSD into my iMac—having to remove the screen, etc.—seemed a bit daunting.
Had the whole job done within an hour. So much easier than I expected it to be. (I've put an SSD in a MacBook Pro too which was more tricky by comparison). My iMac is now like brand new. Incredibly fast. I'm really, really pleased.
