    Since the public version just came out and anything written about the beta versions may not apply, I’m wondering if I install 10.13 with the firmware update to my 2010 Mac Pro, will that affect my ability to boot 10.6 off another internal HD?

    No, it won't affect that at all.

    Thanks, that answers my concerns.
    I'll try the 10.13 install tonight
