Everything is said in the title. Great product, in addition to all those who doubt about compatibility with Apple and iMac, you can buy eyes closed. I made several sites to find the right price and compatibility. Thanks to the comments left by other shoppers, I decided and I am completely satisfied. I have a mid-2007 iMac with 2GB of memory, this one rowed since installing Mavericks and 4GB of RAM with these brand new, compatible, saw my mac, it rejuvenates. For 47 euros it does not worth to miss more and no need to change mac !!!!
In short, do no have realistic fears it works perfectly on a mid-2007 iMac .....
