As a computer technician and ex Apple Care rep i really appreciate this memory. The installation was very easy, just remove 10 screws from the bottom of your MacBook, remove old ram, install new ram, replace case bottom and you are ready to go. Remember to turn off MacBook before doing this install. Do not just close the screen. My clients MacBook boots up 2 minutes faster than before. Google chrome runs great with multipe tabs now. Before it would just sit there with the spinning beach ball and never open a second tab. The value of this memory is excellent. Apple charges a very high preimium for memory and this is atleast half the price for the same quality of. I only gave this product 3 stars on the good for gaming question because i couldnt really test it for gaming on a Mac since Mac games are not really memory intensive. But what games and apps i did run ran great and any app or game from the app store should run great. I would recommend this Memory 100%

Color: 1600MhzSize: 16 GbVerified Purchase
These RAM sticks are for my husband's iMac [Late 2013, 27" screen] and he just wanted to upgrade the RAM. NOTE: The product description on this [CMSA16GX3M2A1600C11] says it's specifically for MacBooks [quoted from this product description: Compatible with MacBook Pro (13-inch, Mid 2012), MacBook Pro (15-inch, Mid 2012)] however it IS working in my husband's iMac, the user-accessible RAM slots on the back are sized specifically for this type of RAM, and on Corsair's site, their compatibility description says it's tested in their labs to work with virtually every MacBook, iMac and Mac Mini made after 2011. The back of this package lists a few specific model numbers, which are specifically MacBooks. Long story short, it doesn't explicitly say that the model of iMac my husband has will be compatible with this RAM, but it DOES WORK!

So here's the low-down of how it went.

Husband had the stock RAM (2 sticks of 4GB RAM = 8GB, two open slots) and he ordered two extra 4GB RAM sticks from SimplyMac to fill the two open slots. It worked just fine, but he decided he wanted more power.

So he ordered this RAM, 32GB of it. Took out the power cable, inserted his house key in the slot to pop off the RAM cover, inserted the 4 sticks of RAM into each slot, popped the RAM housing back in so the cover would close all the way, put on the cover, plugged it in, and pressed the power button. Nothing. ....weird. Pressed the power button again. Nothing.

So he shut it down, pulled the plug out, used his key to open the RAM housing, took them out, and re-seated them thinking maybe they weren't put in correctly. They were all the way in, not upside-down or anything, so he put them back in again, closed everything up, plugged it back in, tried to power it on... Nothing.

So he did the same thing again to get the RAM out, and just to make sure his computer wasn't somehow broken, he put the old RAM back in. It turned on. Phew, okay, we didn't f*** it up. Lol.

Turn it around, open the housing, take out the old RAM, and this time try putting in half new and half old. It booted up, though it took longer than expected, and when he booted it up he went to the Apple menu > About This Mac and confirmed it was saying it had 24GB of ram (8+8+4+4) so all the RAM cards were indeed hooked up and the computer WAS recognizing them.

Okay. So they're working. This means the computer is probably being stubborn and after more trial and error it should work. Shut down, turn it around, unplug, open the RAM housing, take out the 2 default sticks of RAM, put in the other two new ones, close it all up, plug it back in, turn it back around, press the power button... anddddd this time it beeped, when it didn't before. So it was saying something's wrong, but still not booting.

If my memory serves me correctly, he tried putting back in a stock RAM stick one more time and it booted, then he put all Corsair RAM in it, and then it FINALLY WORKED!

He was doing NOTHING differently. Same exact thing, every single time, and it just took several tries to finally get it to work.

It has successfully powered down and restarted multiple times. There's not much of a difference in boot-up time between when he had 16 gigs (stock+aftermarket) and 32 gigs (all Corsair), however, some processing does seem to be having noticeable improvement. We watch lots of anime shows that download in .mkv format and have separate subtitle/audio/video titles and he converts those to a different file format before we watch them, and he was able to convert a full episode (HD, with subtitles, into a significantly smaller file) in about 2-3 minutes. Not exactly sure how long it took before, but he estimates it's about 30% faster than it used to be.

So far, are we happy with the investment? Husband says "Yeah, definitely." :)

I figured I should post this in case it's a common occurrence for other people like the guy in the reviews who said he put it in his Mac Mini and it beeped. It's entirely possible that if that guy tried taking it out and putting it back in a couple of times that it would have worked. I honestly don't think he was doing it wrong. My husband was doing it right and didn't change anything at all in the way he was installing the RAM between when it wasn't and when it was working. So, if it happens to you, don't give up on the first try!

Updated.....This made a huge difference in my Mid 2012 MacBook Pro with i5. I only had 4gb and it was so slow after upgrading to Catalina. After finding out Catalina uses 2gb I decided to upgrade to the 16gb. Extremely easy to install memory. Took out the 2 - 2gb sticks and replaced within 5 minutes. All 16gb showed up without an issue. Logic Pro X and Chrome can be used again without issue. Runs 10x faster. No more spinning ball and walking away for 15 minutes.

I added a 1TB SSD and it’s faster than when I first got the computer. Now my computer turns on in 30 seconds.... Amazing upgrade. I can do heavy load editing and production on this now.

Works perfectly on 2012 year 13" MacBook Pro. Speeds things up so that the little spinning ball either doesn't show up any more or disappears quickly. Even Microsoft programs work faster! Very easy to put in, follow the instructions on line at the Apple site, but make sure you ground your hands AND the MacBook while doing the installation (to prevent ESD damage) and that you have Apple grade tiny screwdrivers and pry tools to take the back cover off of the computer. Also make sure to capture the tiny Apple screws and put them back in exactly the same holes they came out of (they are not all the same.) I also recommend a bright light and some magnifying glasses. While you have the cover off, you may want to vacuum off any dust on the cooling fan if you can. After all that, just turn the computer back on, wait a bit for it to recognize the new chips, and away you go!
