As the title states, i have a 2009 early iMac 24in that I'm going to be selling soon. I also have a mid 2012 non rentina macbook pro. Few months ago I got the mbp and i swapped out the HDD for an SSD. I plan to sell the iMac that i have but i dont want to sell it with the HDD that is in there currently. Theres 8 years of use on it with so much stuff that has been saved and deleted and what not. I'm looking to take the HDD that i took out of my mbp and swap it with the HDD that is in my iMac before selling it. My question is, is the HDD from the mid 2012 mbp compatible with a early 2009 iMac? Standard HDD: 2009 iMac - 640GB HDD 7200rpm 2012 mid 2012 mbp - 500GB HDD 5400rpm That was pulled from everymac.com but I'm not sure on connections if it will work with the motherboard or not. Thanks!
