    Like steroids for my computer!

    Replaced the 4 gigs of memory on my Mac Mini with these for 16 gigs. Fantastic improvement in speed. They were simple to install. Great value and something I should have done several years ago.

    Works great.

    I do a lot of school work on my MacBook Pro, and I like to record on garageband. You need minimum 8gigs in today's world to get by. I had 8 gigs and wasn't enough. If. I had garageband open and a couple of other apps, computer would be very laggy. Don't have that problem anymore.

    Working with MacBook Pro MD101LL/A

    Working on a MacBook Pro mid-2012 (MD101LL/A), originally with 4GB; now it's maxed out at 16GB. No problems so far, either on Mac OS Mojave or Mac OS Catalina. So far, working as expected. The increased performance is obvious, although not still fully noteworthy (I'll further upgrade the MBP with an SSD drive for that), but the memory upgrade in itself is fully functional and working exactly as expected and advertised.

    Memory, To Be Or Not To Be

    If you ask any computer tech you will find the same answer, you can never have too much memory,so I bought more and I am glad that I did. It made a world of difference.
