Reviewer: Lawrol Location: St. Paul, MN Age: 55-65 Experience Level: Home User Owned Product: less than a month
Rating: 5/5 Works as advertised in my MacPro1,1 June 20, 2017 Bought this extra memory for my 2006 MacPro1,1 because I was upgrading it to be able to run El Capitan (yes, you need a modified OS to do this; I bought a modified El Capitan on a hard drive on eBay). Working like a champ.

I would recommend this item to a friend! Customer Videos:
