Rating: 5/5 Excellent RAM October 17, 2016 This is my first review for MacSales.com, but nowhere near my first purchase from them. I've been buying RAM, hard drives, other accessories, and a couple of used Macs from them for quite a few years. I seem to remember buying RAM for a Powerbook 3400; that's a long time ago. I have never had any sort of problem with OWC RAM. Their online RAM selection system has always helped me find the right RAM for my Mac; their shipping is incredibly fast, and their customer service is excellent.

Reviewer: Anonymous Location: Dalkey, Ireland Age: 55-65 Experience Level: IT Professional Owned Product: less than a month
Rating: 5/5 Fantastic improvement May 14, 2016 A completely transformed internet browsing experience.

An old 2007 white Macbook went from 'unusable' with 2Gb ram, to 'effortless' with OWC 2x2Gb. It had been running out of memory on loading a single newspaper webpage - thank you the 'Daily Heil', er, Mail - and filling the very small free 2Gb hard disk space (my fault, partly, for choosing too small a partition size). Now it nearly always has 1Gb ram free on Activity Monitor no matter how many windows, tabs and applications are open. And the hard disk free space is unused. Only sorry I persevered with 2Gb ram 'unusable' performance for, ER, 3 years. Doh! So don't do what I did - upgrade today! ; )

Interestingly, the question of whether 4Gb ram would be sufficient ($33) or 6Gb was needed ($110) is resoundingly answered as '4Gb is plenty' (for internet browsing only, with OS X 10.6 Snow Leopard).

Browser upgrades and newspaper webpage changes previously increased the load on the system from 'trivial' - 2Gb of ram is plenty - to 'ridiculous' - 2 Gb ram is unusable. With 4Gb ram - and OSX 10.6 - it's back to a 'trivial' load on a 2007 white Macbook. Pageouts remain at 0, almost entirely. Previously they were, er, rather large - 1 Gb plus in an hour. CPU use now is heavy, but fine. Much heavier than previously. Disk use seems to now be 4Mb/s versus as high as 20Mb/s with 2Gb ram. (Yes, it is on a USB 2.0 external HD. Don't ask!) All in all a great example of going from ram bottlenecking performance at 2Gb to a well balanced system at 4Gb.

Looking forward to testing a 2009 white macbook with 2 or 4Gb ram and HD or SSD and comparing the difference in Activity Monitor between OS X 10.6 Snow Leopard and OS X 10.11 El Capitan for the same load.

Rating: 5/5 OWC RAM has increased the speed of my computer significantly February 26, 2016 The 4.0GB Kit (2x 2GB) RAM has significantly increased the speed of my Mid-2007 iMac running on Snow Leopard. Wish I'd had done this sooner. The RAM replacement video was very helpful and made the RAM very easy to install. Furthermore I believe the OWC representatives are extremely knowledgeable and steered me in the correct decision for my purchase.

Rating: 5/5 Great product, great service February 5, 2016 My wife's nine year-old MacBook, running under OS X Snow Leopard, version 10.6.3, had become so slow as to be unusable even for simple searches on the internet. Installing Linux (SuSE 13.1) helped somewhat, yet the 1 Gb memory which the computer came with in 2007, doesn't seem to be enough for browsers in 2016. The system was swapping all the time, with several 100 Mb in swap space. Putting in OWC's 4 Gb memory upgrade kit took a few minutes, thanks to a great installation video on the OWC website. Now, the MacBook is running like new again, no more swapping, no more waiting for internet pages to load, Google Hangouts works fine, no more constant running of the ventilator. -- The package took about a month to arrive in Germany, probably because of customs procedures, however, the success of the upgrade was definitely worth the waiting time -- as well as the money spent. (We'ld have had to buy a new computer otherwise.)

Rating: 5/5 Excellent Value, Top Quality! January 15, 2016 I was given a 2007 Mac Mini with 1.5GB ram (which just isn't enough today for browsing), so I bought the 4GB upgrade that OWC offers. Viva la differance! Just what this little machine needed. I was experiencing the dreaded beachball almost constantly with multiple tabs open and now the beachball is seen next to never. The machine is faster, too. A GREAT, inexpensive upgrade that made a HUGE difference- from frustration to pure enjoyment. Thanks, OWC!

I did have a problem with delivery (not OWC's fault) and UPS ended up delivering on a Saturday, which surprised me. They were two days late from their scheduled delivery. Again, no fault of OWC.
