Rating: 5/5 No problems, 2 modules and many years later October 27, 2014 I refurbed an ancient TiBook for someone without one, & bought a 2nd DIMM since I noticed only 1 had been added (by me) over a decade ago. The previous one was also an OWC module, so I am happy to say, OWC sells quality products. I encourage Mac Users far and wide to check OWC first because of their great support and rock solid hardware offerings. After almost 20 years, I can’t recall a time OWC let me down.

Rating: 5/5 This is a great product and easy to install. April 23, 2011 I needed more memory to an older system. Using this site(OWC) was the best way to complete that goal. The product is of great quality and my system is working up to top speed of its' improved quality due to the product. The company had it in stock and shipped it out. Thank you!
