    MP 4,1 Dual boot after High Sierra?

    I've got a MacPro 4,1, already updated firmware to 5,1 firmware. Runs great. If I upgrade to High Sierra, it wants to update my firmware to the HS version. Can I still multi-boot to Sierra after this firmware updating? Are there any other multi-boot issues after HS update?
