Because of the limitations of the new imacs, I decided to update my buggy 2008 imac running 10.6.8 to 4GB RAM to see what difference it would make. Its startling. Imac runs twice as fast and is gremlin free. Switching memory wasn't quite so simple for this novice because the memory didn't just snap out, but one really has to pull very, very hard-- hard enough to make me wonder if I would break something, but so what... Once out however the new memory just slipped. I closed up, plugged the imac back in, turned it on and took a deep breath. The result was much more than expected. I would recommend this item to a friend!

Great upgrade for my MAC!!
December 13, 2015
Memory arrived well packaged and quickly after ordered. Easy to install and I immediately saw an increase in speed. Really woke up my 7 year old MAC. I am running 10.6.8 Snow Leopard. The only negative is I waited too long too do the memory upgrade! Thanks to OWC for a good product and great experience!! I have saved OWC in my bookmarks and will definitely use you again for my MAC needs! Thanks again! I would recommend this item to a friend!

Simple Upgrade Brings Big Improvement
September 23, 2015
This memory upgrade was made to a base MacBook 5,2. The extra memory let me upgrade the Leopard OS to Snow Leopard and then straight to Yosemite. Coupled with a 120 GB SSD replacement for the standard 5400 rpm 120GB Hitachi drive, my 2009 MacBook performs like a brand new machine. The installation was a piece of cake. All I needed was a nickel to open the battery compartment and a small Phillips head screw driver to remove a bracket. I would recommend this item to a friend!

4.0 gb update not so noticeable
September 13, 2015
I updated my iMac from 2.0 to 4.0 gb, but there was not so much difference. Updated my iMac mini to 16.0 gb which was much more noticeable.

Works as advertised!
September 3, 2015
The problem with writing a review 6 years later is it's hard to remember what the product was used for. However, I'm almost 100% certain this went into (hold your breath) my Lenovo laptop, which also takes the same RAM that my Macs do. I've never had any problems with it, and it performs as advertised. I would recommend this item to a friend!

I was having difficulty running Symantec Antiviral Utilities on a 21 inch iMac with only 1 GB of memory and running Mac OS X 10.7.5. Once I upgraded to 4 GB, the iMac flew like a bird! I would recommend this item to a friend!

4GB Memory for iMac
July 4, 2015
My older (2008) iMac was struggling with Yosemite so it was time to upgrade memory. Ordered on a Sunday, here by Wednesday. Took 5 minutes to install and made all the difference in the world. Have been using OWC and they never let me down. Fast, inexpensive and they know Macs. Doesn't get any better. I would recommend this item to a friend!
