I installed a brand new 8TB SSD kit, in my Mac Pro 2019. From a 2TB kit with Sonoma.
Step 1 - Apple Configurator 2 DFU mode
Step 2 - Reinstall computer’s original version of macOS (including available updates): Option-Shift-Command-R.
Here I ran into problems. Connected to the Apple server, but timed out several times.
Step 2a - Create a bootable USB.
I had to restart multiple times to get the USB installer to show up in boot, holding Option key.
Step 2b - Choose macOS Monterey installer.
Step 2c - Connect to internet. A bootable installer doesn't download macOS, but it does need an internet connection to get firmware and other information for this Mac model (according to Apple).
Step 3 - A spinning globe confirm the connection to Apple server.
I can not see activity on my gigabit switch. Will have to wait and see if it times out again.
...
Step 3a install macOS
The last time I installed a new 4TB kit on my other Mac Pro, I had no issues. Perhaps because I had Monterey installed.
This machine had Sonoma installed. Probably with some newer firmware. Although I am just guessing here. But I thought the DFU reset and subsequent internet retrieval of required firmware should be fairly simple.
I have installed a Radeon Pro 580X temporarily, instead of the Radeon Pro W6800X Duo. If that was causing the issue. But it seems to make no difference.
Have anyone else experienced similar problems? Or know of a solution?
