    I lease my notebook through my employer every three years and have just received my new notebook with the latest operating system. Trouble is...i have an audio recording software program called Pro Tools v. 9. which won't run on the new operating system, I think it's Maverick. My last notebook ran Snow Leopard and this was fine.

    My question is...if I purchase Snow Leopard can I swap this out with the new system?

    Nope, you can't go back.

    For all intents and purposes, the oldest version of OS X you can install is the version that came installed.

    SL does not have the device drivers needed for the newer laptop, it simply will not work, regardless of how much hacking/tweaking that you try.

    No, you can't.

    Snow Leopard doesn't have the right drivers for the newer Macs, so I'm afraid you are stuck with Mavericks and onward.

    You might be able to run Snow Leopard in a virtual machine, but this would be at a performance penalty and probably too high latency for audio work.

    Get a new version of Pro Tools, or update it if possible.

    A Mac cannot run an OS older than the one it came with.
