Installed the new OS X Yosemite v10.10 on iMac (24 in Mid 2007) &amp; it has slowed the computer down Will this memory fit my machine &amp; solve the problem

I had a similar bad experience with installing Mavericks on a similar iMac. While the additional memory was helpful, I don't think the newer OSs are exactly compatible with legacy models; we had overheating and random shutdown issues. We eventually rolled back to Snow Leopard and it's been much better since.

Not that I am saying that the other people who answered are wrong, but I have the mid 2011 model iMac, which came with 4gb of RAM, and it says on the box and on the Apple website that it is not upgradeable. On mine, I was able to take off the back cover and there were two empty RAM slots. So I replaced the two 2gb RAM sticks with 4gb, and added 2 more 4gb of RAM. I now have 16gb of RAM in my computer and it works like a champ...performance and speed wise.

Hi. I have macbook, and never intrested about hardware configuration of imac. As I see in this acrticle http://support.apple.com/kb/HT4621 you can use this operating memory. More information you can find with Google and search string like this: imac 27 inch mid 2011 operating memory upgrade 16 gb

I'm not a mac guy, but here's a page you can check to see if you have the right ram... http://www.everymac.com/systems/apple/imac/faq/imac-g3-memory-upgrade-replacement-instructions.html

I have a MacBook Pro mid-2010 version, also upgraded to mavericks. I bought and installed this memory end of December. No problems at all, works great, huge improvement in speed. Even though official manual says it can only handle 4gb don't believe it. I also switched out hard drive for a SSD which made an even bigger difference in overall speed than the memory.

Just want to chime in for anybody wanting to upgrade their Macbook Pros. Both answers are correct here. Usually faster RAM would not affect compatibility. This time however it does. If you are using a Mid 2009 Macbook Pro you need to buy RAM that is the same speed as the RAM currently in your system.

I would think that the best answer to this question could come from an actual iMac repair person, there are times when the seller can tell you what systems the memory sticks are compatible with. If they can't provide this info drop in to your nearest BestBuy or call and ask, I'm sure you do not want to waste cash or cause damage to you computer to find it's not compatible. Also check they packaged disc or information for your Mac system online, it might point you in the right direction...best of luck!

I have a 2009 iMac and went from 2 gb to 16 and it is great. Check on your computer it will tell you what kind of ram and how many slots are available.

I've tried using memory that states Servers Only... and found that although the memory will fit in its desired slot... it will not operate... So I'm going to have to say if your IMAC isn't a server it won't work....

I have not needed to have extra Ram on my computer but I remember that I saw an Apple website that listed fixes and other issues for iMacs. I'm sure that you could find directions for your issue.

I bought 16GB of RAM for my 27-inch iMac with Retina 5K that I purchased in Dec of 2014. It's working great! As others have said, install in slot 2 and 4. Basically, I didn't take out the original RAM from Apple and just inserted the ones I purchased. That's it. It was good to go. I upgraded from 8GB to 24GB.

0 delay on video and audio OSX or Bootcamp but I noticed it runs smoother when I added 24gb of ram in my Imac.

I have a late 2009 iMac i7 my internal drive for writing isn't functioning like it should. I borrowed a friends external rw dvd/cd drive by Apple and haven't had any difficulties. Writes perfectly fine. I'm not running Yosemite.

It certainly is...I have the same model and it worked perfectly. Happy upgrading!!Addendum: If you're purchasing this to upgrade to Mountain Lion, I recommend that you also download one of the freeware memory checkers from the App Store. Even with the 4GB max RAM, OSX 10.8 is very demanding of the system's resources and you may need to clear your RAM from time to time for your system to be responsive. I usually clear the RAM 3-4 times a day, but I use some rather intensive apps. Cheers!
