2013 Mac Pro firmware issues

[3hl3rt]

Hey,

we have two 2013 Mac pro, which I am trying to upgrades to Monterey.

When I try the normal installer (from settings) it starts as expected, and reboots after a while - but without upgrading.

when trying to do the install from a usb stick, it reaches a point where it fails with “unable to verify the firmware…”

the same thing happens on both machines

I initially thought that it was due to the Samsung 970 ssd pro I am using, so I tried with the original ssds as well - same thing.

any thoughts?

Does it have all the Big Sur updates? I am running it on an 980 Pro.

Not the latest - but would that matter on a clean install?

Firmware Updates are included in some of the OS updates, so maybe there was some in the latest Big Sur update.

that didn't help...

I am using this board for the SSD

For M.2 PCIe SSD modules (Mac Pro (Late 2013) cylinder) |

but even with the original SSD, it doesn't work - could the board in any way be the culprit?
it is quite a bit of work to remove it, and it is very fragile - so would rater avoid to try

a bit of progress - I got beta 6 installed!
but it won't upgrade to beta 9... same as before, it goes all the way to the reboot, and then no change

I would try an external ssd for install

The firmware will not update with the AngelShark Carrier Board™ installed. This is a known issue. You need to have the Apple SSD or NVMe SSD with a simple adapter installed only.
