Parallels 17 No Passthrough, No PCIe cards passthrough, No Parallel-SCSI. Parallels 16 No FireWire Passthrough, i havent tested Parallels 17 for FireWire Passthrough. OSX SnowLeopard Server 10.6.8 Only USB passthrough is too limited. The idea of installing older OSX is to use older HW with older Drivers... Not compatible with Newer OSX. But. without HW passthrough, its pointless. New MacPro 7,1 2019 or MacMini 2018 or MacMini 2014, 2012 cannot boot OSX SnowLeopard, without SnowLeopard there is No Rosetta PPC Emulator, and No driver compatibility. some Drivers may install in HighSierra, but Software only works in PPC or Rosetta. i have tested PCIe SCSI card, Firewire to SCSI adapter, Does Not work in Parallels 16 / 17. The only way is Native, Real Hardware, Works OK.
