Pros: .

Cons: I bought a new Macbook pro 2012 in june, and i wanted to upgrade to 16gb. I bought this Memory last week, and installed it today, and right after 5 minutes, my mac froze. My mac has never ever froze on me before. this is the first time. I restarted and tried again and the same thing happened. 5 min no problem and then it freezes. I read the reviews on newegg but most ppl said it works with no problems. But after all these issues i was faceing today, simply googled Mushkin Ram and theres enough ppl complaining about the same thing. Ive learned my lesson tho, i aint goin cheap with upgrading my mac. And my best advice, we spent over 2000$ on our macs, the least we can do is spend about 150$-200$ on a proper set of Memory. PCE
