Rating: 5/5 It really works! July 19, 2016 I'm a very skeptical person, but, I've used my 2007 MBP 17" Santa Rosa as a dedicated FCP 6.06 editor for almost 20 years and was wondering how long my luck would last. So, I started thinking of upgrading when I read how I can get 6gb of RAM, even though my MBP is supposed to max out at 4gb. And that's why I decided to give my review. OWC rightfully deserves their accolade for providing NT for an old MBP that I love.

Rating: 5/5 I am fully satisfied with this memory 6Gb set July 17, 2016 Hello from a french customer ! I'am living in the south-east of France and using a mid-2007 iMac. MacSales.com was the only reachable site to find how I could expand my poor 4 Gb built-in memory. I probably did not choose the fastest way to receive my order but I had the best information from MacSales customer support. The memory set was delivered in perfect conditions and it's perfectly working.

One more time; many thanks to MacSales xavier.licari

Rating: 5/5 Brilliant - Possibly the best thing I have ever bought online June 26, 2016 I never write these reviews....but I have to share in this case.

My old mac had been a loyal servant for over 8 years, but had poor performance. Took for ever to do anything. I bought a new one - top spec, over $3k. But what to do with the old one. My kids weren't interested as it was sooooo slow. A $112 investment which i thought would be a waste of money was spent on this memory. 3 minutes to swap the memory - (one screw and its done), and no risk to the machine. The performance from 4gb to 6gb....wow. Its almost like new. Almost as quick as the brand new one I bought....wish I hadn't now. The kids love their 'new mac' Don't hesitate. It works Possibly the best thing I have ever bought online.

Rating: 5/5 Transformed the machine May 3, 2016 I installed the kit into an early 2008 Macbook Pro (4,1). Definitely worth doing: The machine uses the 6 GB, is happily running El Capitan and performs well for everyday computing tasks. It was unusable before.I subsequently installed an OWC SSD which made it even better.

Rating: 5/5 Memory as Advertised May 2, 2016 The memory maxed out the memory capability my early 2008 Macbook Pro which came with only 2 GB. It greatly inproves the speed of many processes. I don't know what the durability will be, but I have purchased memory from OWC several other times, and I never had a failure!

Rating: 5/5 this site offers great support April 28, 2016 According to Apple my 2007 iMac 7.1 can use no more than a maximum 4 GB of RAM, to which I upgraded from the factory configuration long ago. But when using the machine I could sometimes hear my internal hard drive repeatedly thrashing, especially when I booted the machine into my Windows 7 Premium Boot Camp partition, and I desperately needed to find a solution. When the MacSales site told me that despite what Apple says my iMac could use 6 GB of RAM my experience with MacSales told me that I should trust their advice. So I went ahead and made the purchase from them. Their installation guide was clear. The 6 GB RAM passed iterated performance/logical testing by the memtest utility with no problems. System Information shows 6 GB RAM to be available and in use. Machine performance has improved. Unfortunately RAM upgrades always entail significant waste, and MacSales' trade-in program is of no real help: for the 4 GB of RAM that I replaced with their 6 GB package, MacSales only offered to pay me well under $10. Still I am pleased.

Rating: 5/5 Great! April 9, 2016 My RAM arrived sooner than I thought it would, and now my 2007 iMac 24" runs with fewer problems! Crucial doesn't sell this RAM that expands the capacity of my iMac, so this was a really big deal for me. Helps me put off buying a new computer for a while!

Rating: 5/5 Up-Graded Memory April 9, 2016 Recently up-graded the ram in a MacBook Pro and an iMac so that El Capitan, hopefully, might run a little faster. I'm seeing some improvement. Both of my machines are 2008 models, so 6GB maxed them both out.

Rating: 5/5 Old laptop new again February 10, 2016 Just wasn't ready to give up my old laptop that was still in great condition on the outside but getting slower on the inside. Upgrading to the 6gig memory upgrade was brilliant. It runs like new now so I can wait another year or so before I have to upgrade to new! Highly recommended if you want to get more life out of an old friend.

Rating: 5/5 This product did exactly what I was hoping for. January 8, 2016 Needed to boost processing speed on my mid 2007 iMac. Added 6GB RAM on 2 separate cards (4GB+2GB) and noticed better performance immediately. As I've never tried anything like this before on my own, OWC's online installation video was very helpful. Straightforward and very pleased I'm able to keep my old iMac going.
