Review: Works great - Originally, I didn't think my RAM could be upgraded, I have a 15" mid-2012 MacBook Pro with 4GB. I read some of the reviews from others who have this model and even though the Apple website says it only holds 8GB, apparently people have been successful with 2 8GB sticks. I don't use my laptop for gaming, but I use fairly large programs to build websites, and just a lot of general multitasking, so I opted for getting 2 sticks of 4GB (so 8GB total). It was easy to install, I watched a YouTube video for my specific model. I did have to purchase a Phillips head #00 screwdriver from the hardware store, it was $5. Make sure you put the screws into a little bowl or something because the top right 3 are longer but the others are the smallest screws I have ever seen. When I first turned on my computer again, only one RAM stick was reading, the other said "empty". I switched them out again, putting the top stick on the bottom and the one I had on the bottom, I put on the top just to make sure it wasn't the RAM itself. It wasn't, I was an idiot and didn't have it in right I guess. Second time booting up, I went to About this Mac and Memory, it was reading correctly at 8GB total. The first thing I noticed was that when I switched user accounts, it loaded right away, as before it would take a good minute or more to switch over to the other user's log in screen. Also, my iMessages app would take ages to start and load messages, it worked almost instantly. My MacBook is running really fast as compared to before, so I am very happy with this purchase! I can't speak to using a total of 16GB of RAM because I didn't install that, BUT from other reviews I definitely think that it's fine with this particular model. Here I was looking at buying a new MacBook Pro, I just saved myself literally $1000 lol! This brought some new life back into my computer, so if you're looking for speed and loaded apps/multitasking it's totally worth it, I definitely think I have myself a couple more years on this bad boy.
Review: This Kit Can Really Boost Your Productivity, If You Know What You're Doing... - This kit worked great with my Mid-2012 MacBook Pro 15''. To start off, I'm not a gamer. I don't do heavy computing and I'm not a big computer nerd. I use my computer for everyday things - surfing the internet, writing, using my calendar, communicating with friends, Excel/Word/Powerpoint, music & sampling, along with some designing (with Photoshop & Illustrator). Before I bought this, my computer was abnormally slow even though only half of my hard drive was full (it was slow to wake up, it took a while for apps to load, and there was always a lag when I switched apps). As soon as I switched my memory from 4GB to 8GB, it made a tremendous difference. All my apps run fast, I never have to reboot my computer (although I still do periodically) and everything feels like when I first got my MacBook. If you're on the fence of buying this, stop. Do your research and figure out if you really need this, otherwise you'll just waste your time, money, and energy. Use the Utilities found on your computer and specifically, "Activity Monitor" to determine how much memory your computer is using. I was pushing 3.99GB when I had 4GB available - that was problem #1. Oh, and if your computer is old, changing your memory is pointless. Just get a new computer. If you're looking to make your computer start faster, the problem isn't your memory (most likely). The problem is your hard drive - so you need to get a faster and bigger hard drive if your computer is too slow to boot up. And lastly, switching memory isn't the magic cure to making your computer run incredibly fast. You still need to take care of your computer - that means, periodic cleaning of your files, cache, and junk. Turning it on and off every now and then, and making sure you back up your files. You really only need to make a memory switch if 1) your apps are slow to load and it takes a while for you to switch from a program like Microsoft Word to Chrome. 2) When you wake your computer, it takes a solid 20-30 seconds before you can do anything. 3) Your Activity Monitor shows that you're pushing the limits for your memory. If you meet all of those qualifications, then get this! If not, figure out what you need by doing a Google search.

## Questions & Answers

**Q: late 2013**
A: yes the 27 inch imac will take this type of ram.it can take a total of 32 gigs in 4 slots(8 gigs each slot)if you choose to max it out but 16 gigs is plenty.the 21.5 inch imac is non user replaceable.

**Q: is this compatible with the latest "iMac with Retina 5K display"**
A: I bought 16GB of RAM for my 27-inch iMac with Retina 5K that I purchased in Dec of 2014.  It's working great!  As others have said, install in slot 2 and 4.  Basically, I didn't take out the original RAM from Apple and just inserted the ones I purchased.  That's it.  It was good to go.  I upgraded from 8GB to 24GB.

**Q: Is this compatible with the Macbook Pro 2.6GHz i7 (Mid 2012)?**
A: I think you have the 15-in model. I have the 13-in. Both mid 2012 are using ivy bridge circuitry means that memory kit can run just fine with your macbook. I still am running this kit for 15 months now with no issues.

**Q: Will this work in my mid 2010 13" Macbook Pro?**
A: Contrary to the "yes" answer, it does not work with the mid 2010 MBP. Look for 1066 MHz for compatibility. I know because I tried this item with my MBP, and had to send them back.

### ⭐⭐⭐⭐⭐ worth it
*by P***3 on June 29, 2019*

This brand that designed this ram in awesome! It can be a bit costly but the ram has great performance, great speed and the ability to process multiple things within a app or over several apps is great. I've compared this brand 8gb to another brand of 16 gb and even at a smaller gb this brand out performed the 16gb. recommend this for those who use light to moderate weight software and app. If you use heavy apps then go for the 16gb of this brand. A key thing I look for to determine if i need to upgrade ram is when i am using my laptop (with proper ventilation) and it is showing a pattern running hot within certain software causing the software and the laptop to lag, move slow and/or freeze. A time here and there is no big thing but when this becomes the norm and the frequency of the laptop running hot while in the software has increased then it is time to upgrade ram. Since upgrading my ram to this brand and gb my laptop has not ran hot. I use this ram on my mid 2012 MacBook pro for light to moderate weighed software and basic every day use.
