    Yes, normal… Your Mac should be allowed to use as much memory as it needs, when it needs it.

    Your memory pressure is low.
    Very small amount of swap, and a little memory compression going on.

    Very normal.

    You can likely ignore those kind of readings, and continue to enjoy your new MBPro.
    If you see the memory pressure go up into yellow, or even red, you will likely see much more swap happening, and finally, your system might get very laggy/slow to respond. That can be an issue where you might want to choose to quit some apps that you might be using at the time, or perhaps restart your Mac.

    This is normal.

    OSX uses Ram in a slightly different way, it uses as much as possible to make access to whatever apps you are using as fast as possible. The only thing you have to look at is the pressure graph as long as it is green you are fine. Mavericks uses Ram brilliantly and will give you great compression and you'll find you can use more like 12Gb than 8 before you get any swapping out to the hard drive, this in itself is not a massive issue due to the speed of the ssd.

    If you scroll down the page, I would guess there were a half dozen threads about this over the past few days.

    You are okay.

    I stand corrected. Slap me with a SSD!

    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.

    This has been bugging me the last few days. Finally did a search here on MR and found this. Thanks for putting my mind at ease!
