Know your gear
Engineered to be compatible with your Apple system, Crucial Memory for Mac takes the guesswork out of a memory upgrade. Since Apple systems often have very specific memory requirements, including particular component densities, speeds, and SPD programming specifications, it's important to buy your memory from people who know Apple computers inside and out. With over a decade of experience manufacturing and developing memory for Apple systems, Crucial makes it easy to find memory that's been designed specifically for your system.
If you're an Apple computer user, you probably expect intuitive, reliable performance from your system. Crucial thinks memory should work the same way, too. For each module it manufactures, Crucial sends it through a rigorous testing process to ensure that you're getting a reliable, high-performance memory solution. Every module that leaves the doors has been extensively tested at the component level for voltage and temperature resistances, signal integrity, and software compatibility. Even better, Crucial modules are lead and halogen-free (DDR3 modules only). The result? Reliable memory that meets or exceeds Apple's own memory requirements.
Unsure how to install memory or have an important question about your Apple system? Let the team of experts help! With a tech-savvy team that's well-versed in Apple systems, Crucial will provide the technical support you need - no matter how old your Mac computer gets. From phone support, videos, FAQ articles, and do-it-yourself guides, Crucial has got the resources you need to keep your system up to speed.
Crucial is a trusted name when it comes to DRAM, and that's no coincidence. As a brand of Micron, one of the largest manufacturers of DRAM in the world, Crucial works with its engineers to design, refine, test, manufacture, and support an extensive line of memory modules. With a product portfolio that includes more than 250,000 different DRAM upgrades for more than 50,000 systems, Crucial has got one specifically designed for your Mac system. For more than a decade Crucial has kept Mac computer owners happy with high-performance memory and outstanding customer service.

Fast and Furious
I use it at home for multiple online membership sites as well as some slot machine games--my iMac 2012 memory was dragging so I purchased compatible RAM here as I already knew they were reliable from when I used my PC--shipping is quick, calls into support are easy and they know what they are doing. Been buying my memory from here for years, won't go elsewhere.

Macbook replacements
We purchased these to replace the memory in a macbook that was 54 weeks old. Yep, 2 weeks out of warranty. Apple, of course, would not repair the computer (problem could not be replicated). Reseating the old memory worked temporarily-obvious problem-known problem. Their own tech recommended this site and brand. What does that say?? So far, so good. No more memory issues.

fast 'n' easy
I'm an architecture student that renders using Rhino + Vray and Blender a lot. I noticed my computer was running slow and decided to change my hard drive to a SSD. I then wanted to boost the memory, which made a positive, faster change in render times. Up until this purchase, I'd never installed a computer part myself, but it was totally worth it because it saved me the expense of paying someone else to do it for me. Plus you feel cool opening up the back of your Mac by yourself :)

Never had to upgrade memory - it was easy!
The memory upgrade was for my daughter's MacBookPro 15" 2011. Her college photography/multimedia courses required this upgrade. It was easy to install and so far works like a champ. inDesign, for example, took forever to load and operate. it was so much faster. Just what she needed to be able to edit her various photos and videos for college!

Worth the Money
It was really easy to install and made my computer a lot quicker. This is almost a necessary upgrade due the fact that every new update that comes out it seems as if my computer slows down because the stock 4gb of ram just wasn't doing it. This upgrade to 8gb allowed my computer to run how a mac should and how it ran when i first got it FAST!

I installed two 4gb modules in my older Toshiba i5 laptop. It came with 4gb originally. I noticed Windows 10 did not run as efficiently as it should. The laptop now is so much better. Instead of purchasing a new laptop for around $500 with the same processor and ram, I was able to upgrade for about $80. I am very happy with things so far.
