Review: Great Product, & Easy to Install - I have used lots of Memory modules over the years, and Corsair has come to be one of my top choices when making a purchase. I recently obtained the Corsair [Apple Approved] 8GB Dual Channel DDR3 1066 PC3-8500 DDR3 Memory for my Macbook Pro 13" (Late 2009 - 2010 model). The memory itself worked on boot up no issues, and as far as the installation on the macbook pro, its not so bad. Granted the install is a lot different than that of the white MacBooks, but it is still pretty simple. All that is required is a small screwdriver and some patience. There are many tutorials on how to do this on Youtube, pretty much its as simple as removing 10 little screws (I would highly recommend keeping them in order, as at least 3 of the screws are longer and must go back in specific holes) and having somewhere to place them safe so they don't fall or get lost. ** Of course as always due care is required when touching or changing components inside your computer, things like a simple static charge on your fingers can be an issue (like when you rub your socks on the ground and shock your friend... not so funny with a computer) ** One thing that I noticed while installing my memory, is that the memory type required by the macbook pro changed sometime between 2010 and 2011 so you may want to verify your memory type in "System Profiler" which can be found in your Utility Folder on your Mac. That will usually tell you how much memory you have and what type (i.e. DDR3 1066, or some other type). If you need to know your maximum allowable/recognizable memory, I would recommend searching your model number on Apples Support page. As to system speed improvements going from 4GB to 8GB of memory, I have noticed that my multi-tasking does not slow my computer down as much, and some programs seem to work a little bit better with the extra memory.

Review: Works great, but we DID have to troubleshoot it first! - 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!

### ⭐⭐⭐⭐⭐ Review
*by M***. on November 24, 2018*

After trying to use some old laptop ram to upgrade my mac mini (2010 model), i found this is one of Apples' products that is finicky when it comes to which parts you can use. While the ram slots are readily accessible by turning the base, the ram itself has generally not been very cheap at all. The price point of this ram, as a pair, made the upgrade much more reasonable (under $100) although still pricey for this generation of memory, having the certification as Apple memory made me feel a bit more comfortable about the 3rd party purchase, and being familiar with the Corsair brand. Overall, this was a good buy, from a stable brand, certified by Apple (which implies this stuff was tested on Apple product), and installed easily. The only reason I would consider not recommending this product is if you are planning to upgrade an older mac product for development as it turns out this mac-mini only supports up to El Capitan, and now that Mojave is out, pretty much everything is dated and can not be updated, so App Store submission with this particular model is no longer possible due to the requirement to be using the current version of Xcode in order to submit. Aside from that, the memory is stable, and as fast as PC3 8500 goes :P
