    Has anybody tried to install Mavericks on the new rMBP? I have read somewhere that you cannot install an older OS X on a Mac than the version it arrives with. Is this because there is no 'easy' way of getting the older OS or is it actually not possible to go through with the installation even if one has a bootable USB?

    It isn't possible because older versions of Mac OS X lack drivers for the newer hardware.

    Depending on which computer you're looking at, the early 2015 model contains hardware that was not available when Mavericks was the current OS. Because of that, Mavericks won't contain the kexts needed to support the hardware.

    Actually, ALL of the 2015 models now have the Force Touch trackpad, that won't work on Mavericks.

    Then is it possible to buy a brand new laptop, an older model that ships with Mavericks, say, the Late 2013 model or do they pull all of the old ones once a new release arrives?

    The general policy is that you can't install any OS prior to the one that shipped with the machine. If you really want Mavericks, your best bet would be buying a used or Apple refurbished machine. If you buy new, Yosemite will come pre-installed.

    Not new, but the refurbs are like new, and you should be able to install Mavericks on a machine that originally shipped with it via internet recovery.
