The computer crashes on boot

Even thought my 2 slots were for "4g" in each, I was told "hint hint by the apple tech" that these would also work, my computer is AWESOME NOW

Before the upgrade, I almost wanted to cry with how slow my computer would handle simple tasks.

Computer is running great and faster

It continues to be a very nice computer and foresee years of service for me

Some people make the mistake of buying ram that is to fast for their computer make sure that the ram you buy is compatible with the computer you have so if your computer can't support more than a certain amount of ram or the speed of the ram, you're computer won't be able to handle the ram

The computer is faster and with less hangups (maybe i need to upgrade to 32 to see full effect).

I replaced the RAM over 2 months ago, and my computer has had absolutely no issues since

It's like owning a new computer.

Updated ran for two different MacBooks and worked seamlessly and computers running great

awesome deal, my computer runs like a brand new one.. such an enhancement

It enhances my computer very much.

Computer runs much faster and does not stall during browsing the internet any longer.

I'd definitely give this a shot if your computer is running slow.

My computer is screaming fast now

(It's like an addiction!), and you're going to give yourself a standard at home that makes you hate your computer at work

My computer continually restarts itself, and the computer won't work unless I take out the 16 GB RAM.

I HIGHLY, HIGHLY recommend anyone with a slow computer to upgrade to more RAM!Installation was breeze and the effects were basically instantaneous after a reboot.

Although this ram kit arrived promptly and was easy enough for me to install, and although my computer noticeably sped up, after a few sessions I still get a slow computer (macbookpro) and I get the beachball for a few seconds.

The computer is a lot faster now :-)

Computer ran so much faster - really worth it!

It's been the best thing I've done, the computer just feels like new

Computer is running slower.

I love my computer again and this has added years to it's life!

16GB is plenty, even for the modern computers

With the addition of this RAM with a SSD, the computer works as if it is brand new

Computer is faster, great for what I do...

The computer got new life and worked even better under Yosemite and now El Capitan

The computer works so much better now and photoshop runs easily and efficiently, no freezing

Super easy to install and computer works great and much quicker

They worked great on my Early 2011 MBP, fully registered, and really revived my 4-5 year old computer

Just got them, just installed them, computer is faster, now working.

I've had the computer for 3 years with zero issues, but now it crashes

a 2012 computer with 4 gigs of ram is fine for normal usage, but you are probably going to notice the slowdown every so often

Computer is super fast now and don't have the rainbow wheel

Amazing the difference between 4 & 16 GB, the computer now flies.

It will take you 5 min or less to install and will save you a ton of time in a faster more efficient computer.

I finally upgraded my laptop to Sierra, and my computer was SLOOOW

The computer was running frustratingly slow after the El Capitan upgrade

The computer recognized them right away and they work great

My computer was always overheating and running rather slow.

In fact, the use of memtest froze the computer while going through the memory

Works great, computer is much faster

Works great, computer is much faster

The first is an SSD but with this my computer works faster and better

However, once I opened Chrome, my computer froze

That, along with new memory makes my three-and-a-half year old computer run like new.

For under $100 I feel like I have an entirely new computer

It arrived on time and now my computer is working much faster

this is an easy way to increase that speed and love your computer again.

Like having a new computer, my old mac is working very fast

My computer is much faster

My wife's 2011 iMac 21.5 has been a great computer.

My computer is running like new again

My computer feels like new again, and everything opens, responds, and closes almost instantly... and video editing is enjoyable again

Works well and computer has had no trouble since installation.

Went from 4GB to 16, and my computer is so much happier now

Made my computer so much faster and works on so many computers, my moms 2012 macbook pro with a DVD player and my old 2010 macbook

Apple's updates like max osx have been killing the 4gb memory on this thing and my computer has been greatly slowing down in recent months

For $100 I feel like I have a brand new computer again
