Please Help - Installation of Proxmox 8.2 on a 2012 MacPro

[MattRiley]

I am trying to install Proxmox onto a 2012 Mac Pro that was given to me, and is considerably faster than the Lenovo p93 that I have Proxmox currently running on.
Every time I try and install proxmox using the iso > usb I get the error as shown in the photo below.
I have tried versions 7.4, 8.1 and 8.2 and get the same error, what am I missing here? Any help would be appreciated, thanks.

Hi,

I'm guessing that this has to do with Apple's old/weird UEFI 1.x implementation - it's trimmed it for their uses and doesn't adhere much to any standard, at least on these older machines.

My best advice here would be trying to install Debian 12 and see if that works. Afterwards, you can relatively easy install Proxmox VE on top of Debian 12, which is also supported installation method.

Or it can be more intricate ...

Thank you for your help, I have successfully installed Debian 12, and I will go through that guide on installing Proxmox on top.

I have installed Proxmox following the guide above, and was able to access the Proxmox web interface, after a restart I have lost both network interfaces on the Macpro, it has dual Intel 82574L Gigabit connections, and as far as I can tell it has removed the driver when i removed the debian kernal as there is a green connection light on the switch when the mac starts up, bus as soon as grub loads proxmox the light goes out and there are no interfaces available. I have plugged in a Wireless USB dongle to get me access and for updates and to attempt to get drivers but after many hours i am still no closer.
Any thoughts?

lspci -k should show you which driver is in use to begin with, you can also check dmesg what was going on with the NICs
