    Hello guys,

    I have a MacBook Pro 2009 with SSD drive in it.
    I want to run Windows from an external drive that I have, but I want to
    install apps on the SSD in my MacBook Pro, which the OS X is installed on.

    Is is possible to reach the SSD drive while running Windows from the external drive?

    Thanks.

    Yes. You will need to make a partition on the SSD in a format that Windows can read and write to.

    As for running Windows from an external with a MBP 2009 - I'm not sure how smooth that will be

    I don't think you'll be able to install Windows on an external drive period. Unless things have changed, Windows will simply refuse to install on an external.

    Even if you could, I don't see why you would, it would be painfully slow over USB 2.0.

    You can most definitely do it with USB 3. Like the above said, USB 2.0 will be slow if at all possible

    The newer rMBP use UEFI which will allow Windows 8 and later to install on an external.

    OP's 2009 machine does not.

    Thanks for the addition! My first Mac was a 2010 model and I remember attempting the same thing as the OP.
