I bought this kit to upgrade a late 2012 Mac Mini. Worked flawlessly, as I would expect a Crucial product to do. Amazon had this for less than buying direct from Crucial, free shipping, and fast delivery. What's not to like?

If you go to the crucial website and have them scan your MacBook, they'll recommend you a CT kit with a serial number that doesn't match this one. As alarming as that might seem, the crucial website FAQ's indicate that the serial numbers may vary for warehouse storage and distribution, and that you should pay attention to the listed specs instead.

Anyways, the installation was surprisingly easy. It consists of a simple unscrewing and removal of the back panel followed by popping the old ram sticks out and popping the new sticks in that even an tech-unsavvy person like me could perform. I found the RAM replacement video guide on crucial's site helpful, since the guy points out a few safety considerations like static discharge and the numbers and placements of screws.

Once installed, I immediately noticed the difference in the upgrade. Applications are opening much more rapidly than they used to, and Parallels for Mac is running in seamless clarity. I highly recommend this upgrade to other MacBook Pro users running on 4 GB of RAM or less.

I was hesitant to buy these from amazon because the product model Number didn't match what crucials website said I needed when I chose my system on their product finder system. Later I was told by crucial that they use the same exact modules but give different product numbers to them depending on what system you input into their product finder. So long story short, I bought them and installed them I. My brand new imac.

My system booted on the first try and all 32gb worth registered in the system without any problems. This is an excellent deal! Apple wanted to charge $600 to go from 8gb to 32gb. I spent less than $300 to do the same with these modules and I got to keep the original 8gb of ram that came with my imac to use I. A different system!

One more thing!
Installing these isn't for the faint of heart! You hand to align them in the slots just right and push them I. Pretty hard to fully seat them. They may seem like they don't want to fit or are too big, but trust me, they fit and work just fine. Just push on then hard and they will go in.

Size Name: 16GB KIT (8GBx2)Verified Purchase
I initially installed this memory in the already-open slots 1 and 3 (the factory RAM was in slots 2 and 4) and got 3 beeping sounds and no bootup. After following the advice of another reviewer here, I turned it back off, opened the memory compartment back up, and swapped the positions of the factory RAM and the Crucial RAM so it went like this:

Slot 1: 4GB Apple RAM (Top slot if iMac is upright)
Slot 2: 8GB Crucial RAM
Slot 3: 4GB Apple RAM
Slot 4: 8GB Crucial RAM (Bottom slot if iMac is upright)

That worked fine and I now have 24GB of RAM installed on the Late 2012 27" iMac.

Tip 1: the Crucial RAM is a tight fit in the memory slots. To get them back out to swap their positions, I first had to remove the Apple RAM so that I could get a better grip on the Crucial RAM.

Tip 2: I had difficulty getting the memory access panel off of the iMac because my finger wasn't going far enough in to depress the button all the way. I used a small key (a screwdriver would work too) to push the button in all the way to get the access panel to pop open.

I'm pleased to report that indeed, 16 GB of RAM does work correctly in the 2011 MacBook Pro, and, it is even recognized at it's full speed: 1600 MHz. All the functions of the MacBook Pro work correctly, including waking from sleep. Having this much RAM may seem like too much, but it is great if one uses several programs at a time or works with large datasets or image files.

Installing this RAM is relatively easy. There are instructions in the MacBook Pro's User Manual and online at Apple Support; even nicer instructions with step-by-step pictures can be found at sites like ifixit. Basically all one has to do is remove the screws on the bottom of the case, being careful to keep track of location of three of the screws that are longer than the rest.

As for quality of the Crucial RAM, the actual memory chips are by Micron, a respected manufacturer that supplies Crucial with most of the RAM they sell. After installing the RAM, I used the Apple Hardware Test (AHT) to verify that this RAM worked as it should in my MacBook Pro. I followed up on the AHT by running Memtest overnight to test the RAM - it passed with flying colors!

You may wonder how come it's ok to use 16 GB of RAM when Apple specified a maximum of 8 GB of DDR3 1333 MHz RAM for the 2011 series of MacBook Pro laptops? As you can see if you peruse the web, there are many, many reports of users installing and successfully using a maximum of 16 GB of RAM in the 2011 MacBook Pro laptops. The reason why Apple specified only 8GB as a maximum is that when these MacBook Pros were released, RAM modules denser than 4GB were not available in the appropriate sized SO-DIMM. With the subsequent improvement in RAM manufacturing technology, it's now possible to use up to 16 GB of RAM in the 2011 MacBook Pros. It's simply the case that Apple has not upgraded the specifications of the 2011 MacBook Pro.

In sum, if you are considering increasing the RAM in your MacBook Pro, and it's a 2011 model, it's safe to use this DDR3 1600 MHz RAM instead of the 1333 MHz RAM. You may ask why would one want to use 1600MHz vs. 1333 MHz. I choose to do so because, surprisingly, the 1600 MHz version was actually cheaper than the slower 1333 MHz type. It may not always be the case because RAM prices are very volatile, but it bears checking into if you are shopping for new RAM.

I spent a lot of time to make sure Macbook 2011 13" (i5 2.3G) will run 1600MHZ. Mixed views all around. Worried this would not work, I actually ordered a set of 16GB 1333MHz from Crucial at over $110 on Amazon, turned out to be not good and had to do a refund. You can guess how surprised I was to spend less than $90 here and have a much better product.

My Macbook Pro 13" 2011 early, which "offcially" states only support 1333MHz, instantly picked up 1600MHz 16 GB without any problem.

My old setting was 8GB 1333MHz. I used to run Photoshop and other Adobe products, Windows 8 on Parallel Desktop and few browsers and many others softwares for web design purpose all at the same time. It would stuck here and there, esp. Photoshop, actually always stuck - made it the reason I want to improve my memory.

It proved to be a wise decision. Now, with all major programmes running, I have no problem. Now I can have a smooth Photoshop and Windows at the same time.

I have always had great experiences with crucial memory and this was no exception! I purchased a set of these to bump up the RAM in my new 27" iMac from 8GB to 24GB and it worked like a charm! My computer is running faster than ever now, and I doubt I will ever have to add any additional RAM to it. However, if I ever do, I will gladly buy another set of these to max out my RAM to 32GB.

Additionally, this product is SO much cheaper than buying from Apple. To bump my RAM from 8GB to 16GB would have cost $200 if I had purchased from Apple! With this product, I am now sitting at 24GB at less than 1/2 the cost of an additional 8GB of RAM from Apple. I could not recommend this product highly enough!

Just wanted to add my two cents that this works with the new iMac 5K (aka Retina 5K, 27-inch, Late 2014, iMac15,1). 32GB at 1/3 Apple's price. Performance is perfect.

I was looking for an upgrade for my Macbook Pro 13” (mid 2012), and after many days of indecision and seek information between CORSAIR VENGEANCE and CRUCIAL, i do finally bought CRUCIAL 16GB KIT.

I’m an IT Database Manager, and i wanted to run Virtual Machines on my mac, now i’m able to run VMs (Linux OS running Oracle Databases and Windows VM with SQL 2012). Everything works very smoothy and pretty awesome.

So i do recommend the 16 GB Crucial Memory kit. It works despite what apple says about just supporting 8 GB of RAM, so i hope this review help you. i also post some photos.

I ordered Prime and within three days i received ‘em… Great shipping services…

Worked perfectly right after installation on my baseline mid 2012 MBP 13". Great performance boost. Runs win 7 on parallels seamlessly, just as if was just another light app. Completely worth it.
