MP 6,1 How to upgrade to Monterey from Big Sur on 2013 Mac Pro

[bassdaze]

I installed a 1 tb Samsung 970 evo nvme m.2 on my 2013 Mac Pro years ago. Of course when I try to upgrade to Monterey the upgrade fails due to the firmware not supported for the SSD. I've read that this can be achieved by installing an Apple ssd, do the upgrade up to the point after the firmware update, re-installing the 1 tb ssd then continuing the Big Sur upgrade. I'm not sure if the original ssd is actually a Apple version...

Is there a way to determine if the 512gb ssd is an Apple ssd visually? Or is there an easier way to upgrade?

Thanks!

Which version of OS X the 2013 model shipped with, is it lower than high sierra? if so, you’ll need to use an oem disk to upgrade the firmware to high sierra, the. You can boot up into disk utility (with high sierra or higher so x) and install os x on your new drive

Ah ok, looked up the versions of OS X. It’s very likely when you boot into disk utility it’s defaulting to an older version of os x (pre high sierra).

I have no non-OEM peripherals, and I can't upgrade my '14 iMac to Monterey. fwiw.
