Will there be NVME booting EFI for 2010+ Mac Pro on High Sierra? For the love of all that's good and holy, someone please answer. • We know Apple has officially added native NVME support AFTER booting. • However I could find no posts saying whether or not someone has actually tested booting off of NVME yet. • In the history of the Mac, there has NEVER been, AFAIK, any type of officially supported internal drive where booting was impossible. • They supposedly would need to update the EFI firmware to support APFS booting, but it's unsurprising if there's not a "beta" of such firmware. • If they're going to do it, why wouldn't they just say so now? EDIT: The APFS FAQ on developer.apple.com states: Can I boot macOS 10.13 from an APFS-formatted hard disk? Yes. macOS 10.13 supports Apple File System for both bootable and data volumes. The 10.13 beta 2 release notes state: APFS support for Mid 2012 Mac Pro will be included in an upcoming seed. Perhaps this is a typo and they meant to say "5,1 Mac Pro"? If so then it sounds like a good sign as far as APFS is concerned. Otherwise, this latest bit is extremely confusing, because I was not aware of any differences between the 2010 and 2012 Mac Pros that could affect APFS support. They both have the same EFI firmware as far as I know. (Please correct me if I'm wrong.) Since we imagine surely adding APFS support requires flashing the EFI firmware, can anyone think of a reason why Apple would not also add boot strings for NVME booting?
