We're so glad to hear our team could help you find the perfect memory upgrade for your 2009 MacBook Pro! Thanks for trusting MacSales.com — we’re always here to help you get the most out of your Mac.
I ordered these modules for my 2009 MacBook Pro only to find out I can’t upgrade it beyond 8GB. Bummer but I have to take the blame for listening to online sites. I returned them for a refund. Again, not OWC’s fault in the least. I should have checked the OWC selector page first.
