    Hey

    I bought my Unibody MB when they were first released last year, and it had 2GB of RAM installed as per the default.

    The other day however, I checked my Activity Monitor and saw this:

    Apparently, I only have 1.75GB of RAM now.
    I haven't touched the RAM since buying my Macbook or anything.

    Any ideas where this 0.25GB of RAM has disappeared to?

    Thanks in advance
    Ben

    I'm not sure why it only says 1.75GB under the pie chart but if you look to the left it shows 1.95GB used + 48MB of free ram which is essentially 2GB of ram.

    Everything appears to be in order, kind of odd that there is a discrepancy between the two though...

    Thanks, I didn't even notice this!

    As you said, strange that they're different.

    A few ideas come to mind...

    I do agree with apunkrockmonk's reply.

    But here are some ideas that I have:
    Try to remove your RAM and place it back in....
    just in case you don't know how to do it....i think it's even in your macbook manual too...

    Reset your PRAM...

    256MB is assigned to the 9400M. In leopard it was reported as part of the 4GB, in Snow Leopard it is not. You haven't lost anything.

    It's snow leopard. that 256mb of RAM you're missing is reserved for the graphics, and won't be shown
    EDIT: Beaten :p
