This product works fine for my Macbook Pro 15" Late 2011 model. I upgraded directly from 4GB to two of these (16GB).
Followed the instructions from: [...]
At this time, I have been using this for 1 week, and I'm able to comfortably accommodate a large virtual machine, many tabs on Firefox, etc.

Upgraded Macbook pro early 2011 after I noticed a substantial deterioration in performance over the years. I ordered Crucial MX200 and a Kingston 16GB ram together. The package arrived sooner than the estimated delivery date which was absolutely fine with me. I followed a video tutorial from OWC on youtube and installation of both items was a breeze. No fitting issues. I'm so glad I went ahead with the upgrades! My laptop's performance has dramatically improved with faster startup/shutdown times, and blazing fast loading of resource hogging applications such as photoshop. I'm using a third party application which showed the memory allocation was nearly 7GB with the applications that I was using. The RAM upgrade seems to give enough room for the laptop to push itself to fire other apps. There have been no errors on the memory through this week of moderate usage. Overall extremely happy with the upgrades.

Having bought my iMac 27" Mid 2011 with 16GB of memory which was all that was available at that time, I did some research and was happy to find out that it could be upgraded to 32GB. I do video editing and have 4 virtual machines that I use from time to time and 16GB was starting to get slightly bogged down with editing and a virtual machines running at the same time. After reading several reviews and making a few inquiries, I bought (4) these Kingston modules. The installation was easy and the iMac booted with the full 32GB with no issues. The OS is running much faster with the virtual machines and video editing now. Running OSX, Parallels with Windows 7 and various photo and video editing software, I have around 16-18GB free! That works for me. :)

Bought one of these in Aug 2012 for my late 2011 15" MBP. 3 years later it's still working perfectly, and I might go ahead and pick up another to upgrade to 16GB. Currently sitting at 10GB with this stick and one original OEM 2GB stick. 10 is plenty for almost all applications, but OSX does have a thing for RAM.

It was easy to add the memory to my iMac late 2011 edition. With my current 8 gig, plus the addition of this additional 16 gig I increased the memory up to 24 gig. Now its a lot easier to use Fusion and my Mac Apps together

Rock solid for a month now, with this installed in the "bank 1" (outer) RAM slot, and one of the factory-installed 2GB DIMMs in bank 0.
No problems, and all 10GB show up in the system, with the DIMMs in this arrangement.

I mention the arrangement because early on, I had also tried putting them in the opposite slots to see if that made a difference in performance.
The Ethernet and Wi-Fi did not work, at all, until I switched them back. Not sure why.

Update: Having no problems running a matched pair of these for 16GB total.

this is a way cheap way to increase the operating capability of your computer. added 16gb to the 4 that came included with our 2012 27" iMac. much cheaper than buying memory from Apple and installation is definitey ok for the uninitiated. would suggest checking out youtube to see some tutorials on how to add memory
