As you say, it currently won't work. I assume that they haven't included the necessary firmware update to support APFS.Has anybody tried to boot off APFS under High Sierra on a 5,1?
Based on beta 4 release notes, only mid 2012 will be officially supported in a future beta.
This is something I've wondered about. I know the 2010 and 2012 are identical physically and from a model ID perspective, but are they from an Apple support perspective?
Will Apple cut off the 2010 from support 2 years earlier, and can a 2010 be made to look like a 2012 if this happens?
It really depends on how Apple decides to go about providing support for the Mac Pro. Apple has not explicitly stated that an EFI/Boot ROM update is forthcoming, only that support will be added in some way.Yes
The serial number would still identify the machine as a 2010 model so it'd be pointless
