    Hi Gary, I have a late 2009 27" Mac which has 4 x 4GB slots of 1067mHz DDR3 RAM. Am running Mac Sierra 10.12.3
    Is it possible to upgrade that memory to say 32Gb?

    Colin: I couldn't tell you without more details (it is an iMac or MacBook, for instance? etc...). But the point of the video is that you can look it up yourself. Give it a try.

    Good one Gary. Very helpful. You could mention how extra memory gives greater speed or helps avoid the ceaseless spinning red ball - if it does. Much thanks. D

    Dally: More memory can speed up your Mac and can cut out delays. But it isn't a given. Memory mostly helps intense work: video editing, photo editing, audio editing, compiling code, etc. If you are just surfing the web and sending email, you may not see much of a benefit. Also, a spinning red ball could be a sign that an app is having problems and memory won't help that. A first-hand look by an expert might be more what you need.

    I highly recommend if you want to upgrade a Mac and have questions about what kind of RAM to use. There's also an app called MacTracker (available on the App Store, or see their site at that has great info as well. As for the instructions, go to or to see step-by-step instructions.

    Spinning beach ball on an older 2009 Colin, too can be your hard drive, back then they were the Serial ATA aka SATA drives. Slower, can't move any faster than the 7200 RPM. In that case with RAM, having a bit more can be a balance. Your iMac won't act as if new, but it will breathe a different life into it, for paging I have a Late 2009 it was 4GB of RAM. I took it to 12GB and the performance is much better. Actual Apple supported is 16GB taking it to 32GB on that processor won't be a boast.
