    I just purchased a new 13" rMBP last month and I can't figure out what is using up all of my RAM. Even from a fresh restart my Activity Monitor is showing only ~4GB of 8GB of my RAM being used. However, if I add up all of the processes listed in Activity Monitor is is nowhere near 4GB. Also, as soon as I open Safari and a couple other programs I get down to <100MB free memory.

    Before I bought this Pro, I was running a 2011 13" Air with 4GB RAM and never had any memory issues...I'm running the same OS, same programs, everything - how am I killing 8GB RAM all of the sudden?

    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.
