This memory is the exact specifications for a 13,2 iMac. However, upon installing it beeped every 4 seconds and would not boot.<br /><br />I can't say the product itself is bad but, the memory should break down which computers it will and will not work on in the description.<br /><br />I put this under 1 star because I know there are lots of people that look to the worst reviews for worst case scenarios and then evaluate the reviewers responses. Again, I don't doubt Crucial is quality memory....just that Crucial or the vendor should list exceptions for PC's that won't work, not the ones it will work when installed.
Caution, you need to assure on another site this will work for you year model iMac or MBP!!!!
