MP 1,1-5,1 Is it possible to boot the Mac Pro 5,1 headlessly?

[iChan]

I've been trying to boot my Mac Pro 4,1 > 5,1 headlessly to no avail. Not only that, I need to have a DVI/HDMI/DP cable plugged in for it to boot at all.

I did read somewhere on these forums that someone found it possible to boot without a GPU. I want to do it to free up a PCIe slot.

Anyone gotten this to work?

I use a dummy plug to get full resolution but have gpu

Not sure if you can boot with out a gpu, especially if you use OC since it requires a metal gpu

Yeah, I have a few dummy plugs lying around, but only for hdmi. The GPU I'm using to boot is a GT120, so it only has mini DP and DVI, but you can get those too. Doesn't solve my problem of booting without a GPU though. Thanks for the input regardless.

MacPro5,1 updated to 144.0.0.0.0 and correctly configured can boot without a GPU, no problem.

Configure everything, set your default boot disk, then you can remove the GPU.

What kind of configuring is required? you mean I have to do something in MacOS? I'm running Linux...

A MacPro5,1 running macOS can boot headless or without a GPU without any issues, once the default boot disk is correctly set, didn't ever tested with anything else.
