Rating: 5/5 What can I say? Better and less expensive September 15, 2020 This memory is faster than the stock Apple 8GB sticks and is so much less expensive than the Apple 32GB sticks. And I trust OWC to be there if there is ever an issue, which I doubt there will be. The OWC memory in my 2013 MacPro is still going strong.
