    I had to install more memory on my iMac (Maverick ate up all of the existing memory), but had never done anything like that. Our Tech Services person at work suggested Crucible and said I could manage it. The website helped me select the correct product specifically for my iMac, and I found YouTube videos of people installing the product on the same version of iMac. It worked just fine.

    Memory, price and fulfillment may be fine but the sites online configuration tool gave the wrong memory type for my MacBook Pro. Transaction was a complete waste on time. Crucial issued an RMA but only give 10 days for a return so I'd either need to have nothing else scheduled in life or pay more for express shipping than the memory cost.

    Luckily the memory is pretty cheap so I can give to a friend or discard.

    Again the memory may be great - I'll never know but Check you device memory specs somewhere else than Crucial web site .

    In an attempt to keep a late 2008 MacBook Pro laptop going, I wanted up upgrade RAM from 2 GB to 4 GB. A search of the internet took me to the Crucial website. Reviews were favorable and the descriptive information was extremely clear that this particular item was compatible with my machine.

      Used the Crucial app to verify the correct memory card for my MacBook. I replaced the original 2gb card with two 2gb cards and found that it was easy to do. Performance increase is excellent.

          Mac Book 13" was slowing up from new operating system advances. By upgrading the memory it restored the speed we were used to. It was an easy install (about 15 minutes), memory worked and was recognized right away.
