    Hi all,

    I recently purchased a Retina iMac and for obvious cost cutting elected to purchase it with the smallest amount of memory (8GB). I have recently purchased 32GB of memory from Crucial to max out my system.

    Before I install the 32GB, I would like to run a diagnostic tool to see how much better my iMac performs with the 32GB than the 8GB. I know it will run faster, but for curiosity's sake I would like to actually see the data.

    Anybody know a good app for this? What should values should I focus on with regards to the diagnostic results?

    Before buying 32GB, did you check to see if you needed that much?

    This should help: How much RAM do I need in my Mac?

    It is quite normal for all of your memory to be in use by OS X. It does not mean that you are running out of memory or that it is maxed out. OS X will manage all available memory, making it available to apps on an as-needed basis. Refer to the following Apple support article for more information on how to understand your Activity Monitor readings.
