 Perfect RAM July 30, 2010
I put this into my 2009 macbook pro. It reconized it right away. I can notice a big change in the speeds
Good value July 29, 2010
This memory upgrade allows fast access to applications, and also increases the number of applications which can be open simultaneously. It is easily installed, although perhaps the design of the computer (Mac Mini) should get some credit for this.
 Bad RAM twice July 26, 2010
I bought this RAM as an upgrade to my MacBook Pro. The RAM seemed good for a few days, but I soon discovered it was the source of my Mac's Kernel Panics that started shortly after installing the RAM. It seemed to be associated with filling a certain area of the RAM, because my machine would work fine, until I had a lot of memory-intensive programs running. Often the problem would happen when putting the MacBook to sleep. At last, the RAM just totally died -- I got the 3 longs beeps of death when I turned my Mac on. What a sinking feeling that is! I put the original RAM back and, fortunately my Mac seemed okay. I returned the RAM to Amazon for a replacement. Amazon was wonderful -- they even sent me the replacement RAM before I had returned the product to them. The new RAM also seemed to be fine for a few days, maybe almost a week. Then I started getting Kernel Panics again. At that point, I decided I would just live with 4G of RAM and forget trying to upgrade to 8G. Amazon was wonderful again about returning the product, this time for a full refund. I questioned myself, that maybe I installed the RAM wrong. But then I answer myself that every time I put the original RAM back everything is fine. So I'm pretty sure that either: out of each batch of 2 RAM chips, at least one was bad each time, or, the Mac OSX Snow Leopard does not handle 8G RAM. Whatever the case, I am sure that I install the Kingston RAM, I get Kernel Panics, I put the original RAM back and the Kernel Panics go away.
You may be suspicious about my report and I don't blame you. I am surprised at this behavior myself since I have been installing my own RAM in PCs for 2 decades and I cannot think of a single instance where the new RAM was bad; until this experience, that is.
Works Perfect on my MacBook Pro 2.66 (late 2008) July 14, 2010
Very easy to install, works perfect, the performance of the MacBook Pro is really better, about 30 to 40% better. I work with virtual machines to test features using various servers running at same time, with 8GB I have 2 or 3 servers and 2 or 3 clients running at same time without any problem. Very Recommended upgrade.
2x4 GB Kingston RAM -Nice! July 12, 2010
I needed 8GB of RAM for my 15" MacBook Pro mid-2009. Installing the new RAM was quick and easy. Ever since getting my MacBook I have had reboot problems when attaching my MacBook to external displays (projectors, TVs, VGA or HDMI). After installing the new Kingston RAM my MacBook no longer reboots - oh, and the RAM is nice, too ;-)
So, bottom line, nice, fast, simple to install and very compatible memory. Two thumbs up.
