Amazing thread and an incredible amount of knowledge here...
I read through the thread but can't seem to find the answer I'm looking for. Apologies if I overlooked the information.
I'm trying to upgrade the bios to
144.0.0.0.0 on my 2010 Mac Pro 5,1. It already has High Sierra, and I recently updated the bios to
MP51.0089.B00.
When I attempt to install 144.0.0.0.0 it doesn't get past the Mojave installer splash screen because I don't have a graphics card with Metal support. Just to be clear;
I don't actually want to install Mojave - I just want to update the bios so I can install a pcie M.2 SSD and have it be a bootable drive. I understand from what I've read on Macrumors that 144.0.0.0.0 has native support for bootable pcie drives.
I attempted to update the bios by following your first post in this thread
@tsialex but again - the installer won't get past the splash screen because the video card is the original ATI Radeon HD 5770 which does not have Metal support.
Is there
any way to update the bios without having a Metal card?
My end goal here is a refresh of an aging machine. It's still pretty fast for a 10 yr-old Mac, with a 10k RPM Raptor boot drive, dual 6-cores and 16Gb of ram, but even at that, the read/ write speeds are still only ~115MB/s. I'd like to improve it a bit more so I can eventually do some 4k video editing. (I've got 32Gb of RAM and a Samsung 970 Evo SSD with pcie adapter on the way - should be here tomorrow.)
Help is appreciated!
