As long as what you order is Kingston part number KTA-MB1066K2/8G it is compatible with any of the Late 2009 27" iMacs (Core 2 Duo/i5/i7's).

Mine is a Early-2009 27" and that's what I used. Bumped it up to 8GB, reloaded Mountain Lion and now it screams like a brand new machine. Can't imagine needing to upgrade the hardware anytime soon. Great deal.

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.

Not sure, worked fine in my mid-2010 iMac. I suggest going to Apple icon on your menu bar and under "About This Mac" is a pane that will give you the memory type. Make sure it matches before ordering.I was super-paranoid about getting the right one but it worked out okay for me. Good luck!!!!!!!!

Depends how old your Mac is. If it only supports 1067MHz I believe the maximum you can put on it is 2x 4GB modules, so a total of 8GB max.

Absolutely perfect for it. You can pick out the various components to suit your wallet and needs, but do NOT skimp on the RAM! And, install a second drive if possible. They're both very inexpensive if you you know where to buy them. I have always used http://www.transintl.com/macupgrades/index.cfm for my HDs and RAM.

The memory I bought for my mac mini will not work in an iMac 24-inc.The Ram speed I bought was 1333 MHz . I did a fast check in Google for the spec of the iMac 24 early 2009 and its memory's speed is slower or 1066 MHz. Before you buy ram memory, check Apple's specs for your machine. This is what I did when I bought my memory. If you buy the wrong memory it could damage your machine so be careful.I did see inexpensive memory for your machine,but, again double check before you buy any memory.GK mentioned 1066MHz DDR3 SDRAM and this seems to be correct, again double check.

I installed this memory in my laptop mac pro. So I'd double check the memory that you need for your iMac 24.

Yes. Bear in mind that the pre-2010 iMac models do not have an add-on option if I recall correctly, meaning that you will have to completely replace your previous HDD (or SSD if you had previously replaced it). If you are confused about the installation process, here is a great link that gives an overview of the steps necessary: http://forums.macrumors.com/showthread.php?t=842548 Likewise, it never hurts to check with the manufacturer since they are the ones who give you your warranty on products. Check with Mac and/or Crucial tech support if you have any specific technical questions that you may have.

Yes, it's the correct speed (1600 MHz). However it depends on how many available slots your iMac has, as to which kit you should get. 2013 iMacs can take up to 16Gb.

Hi Willy, I will answer categorically YES. But, here is a great article from MacWorld http://www.macworld.com/article/1143511/unibody_macbook_review.html where it confirms that 8Gb can be installed. On thing for sure, Kingston makes great quality products. So, after reading the mac-Article, I'm would get the memory. 4Gb won't take you too far. My macMini (with the same processor as your laptop) came with 4Gb once I ran PhotoShop I was swimming in glue!

You need to purchase this model pre configured with the RAM as the 21.5" iMac doesn't have a way for the user to change the Ram themselves (you have to have a service center do it). I recommend getting the 27" model which has an access panel that allows you to change RAM. Plus the screen is bigger! In hindsight, I wish I had spent the little extra for the 27" iMac to be able to have the options to expand RAM and other things in the future.

I used it in my early 2008 iMac.Your manual should specify exactly which types of RAM your iMac can use. iFixit is also a pretty reliable reference.

Yes, this hard drive should work because the 2009/2010 iMacs have a 3.5 inch hard drive bay. (I did a brief Google search, but you should also double check.) Note, however, that in my 8-bay NAS system, the hard drives are audible. I'm not sure how they would sound in an iMac (probably quieter, because the NAS has no case for sound proofing other than a tray around each hard drive. But this hard drive might be noisier than you would like for an iMac.

iMAC 24-inc supports upto 4GB (two 2GB SO-DIMMs) of 1066MHz DDR3 SDRAM; supports up to 8GB. So it should work

I have a 2011 27" iMac and it has 2 thunderbolt 10 gb connectors on the back of it. Purchase a thunderbolt cable and you will have a far better experience than using one of the usb 2 ports.
