Didn't work reliably in MacBook Pro mid-2012
on 4 May 2014
Not quite sure why. Mac seemed to start up OK (and the RAM tested OK) but usually froze before getting to login screen. Suggest getting direct from Crucial to ensure compatibility. Possibly the Mac doesn't like dual voltage RAM - 1.35V is what the computer needs. I returned it for a full refund - full marks to Amazon for that at least.
