Afaik the latest Beta has not yet APFS support for Mac Pro 5,1 (4,1 flashed).

looks like installation and EFI firmware upgrade will work on flashed MacPro4,1 according to the comment of a user here

maybe it would be wise to save a beta installer to be able to upgrade the firmware in the future in case apple removes the EFI updater compatibility with flashed MacPro4,1 computers....

In fact, I recommend do the firmware upgrade now (for any 5,1 that not belongs to 2012 model). I did it already, it's easy. Just run the beta installer, perform the firmware upgrade, and then once reboot, discontinue the beta OS installation.

Even the OS is beta, but there is no evidence that the firmware is a beta firmware. And absolute zero issue from the firmware so far. So, very safe to do it now.

I have 99.99% confidence that the official release will work on the flashed 4,1 exactly the same as the native 2012 Mac Pro. But just in case Apple really did something to block any non 2012 model, we still already done the firmware upgrade.

Not working for me on native 5,1 even with EFI GPU. System does not reboot after clicking "Shutdown" button.

Thats normal.  You have to power it back on and keep holding the power button  until you see the power light start to flicker and hear the  beep sound. After that the  firmware update will start. Don't turn off your Mac Pro at any moment it will turn off by itself.

I did that and it just normally booted the OS despite that special beep and holding the power button.

I need to wait for the final version.

^^^^Worked for everyone else.  You need to read this page of this thread:

And an EFI GPU is a requirement.

Do you have the 5,1 firmware now? What's you actually boot ROM version?

Hi there,

I have an old GT 120 with mac EFI (it is EFI, right?). Can I upgrade my mac pro's (native 2010) firmware?

Thanks
