Sure, the display flashed every now and then - since, now the CPU takes over the hard work in updating the screen contents - but I managed to get to the point where the icon for 'Install macOS Mojave' can be double-clicked. SAFE BOOT (holding the SHIFT key while booting) fixed this - phew! God bless the chaps who put this Safe Boot feature in. OK, High Sierra crashed but it actually booted up to the point when the desktop is generated. Starting with just one monitor, the MacPro booted off in High Sierra and upon logging in (I use multiple user accounts and hence a login screen), the Mac Pro *crashed* after giving some hint of the desktop on the display. Took out all the 'old' cards and plugged two GT630's in. Here starts the nervous journey - as bricking the Mac Pro is NOT an option. Very simple card, no pesky power cables to connect, not enough compute horse-power for intensive graphics - but hey! suits me just fine.īut, I won't be filling others' pockets just for the boot screen - so managed to get two such GT630 for about twenty quid. Then, spotted the humble NVIDIA GeForce GT630 2GB (with Dual DP DVI) (with the Kepler architecture, not Fermi, my puny online research uncovered) claimed to be flashed to support the boot screen. Scrutinising the famous 'bay' for such Metal-supported graphics cards, I avoided the ones aimed at gaming or are capable of loads of compute power (FPS, FLOPs, etc.) but cannot help swearing at the prices flashed-compatible ones fetched. Skint it might look like - but hey, there's a challenge. Talk about being victims in such typical industry squabbles - OpenGL, DirectX, Metal, blah-dee-blah.Īnd no, I am NOT approaching the situation with just loads of cash.

Now Apple decided both cannot be used at all for macOS Mojave - what a w****r shame. Originally equipped with a ATI HD5770 to drive 3 displays, I added a GT120 for the fourth. So, I'd started looking online on 'refreshing' a Mac Pro 4,1 (2009) which I use in a four-monitor setup in office yes, plenty of screen-deskspace is needed to examine logic circuit structures. so no good for this Darth-Vader MacPro. Still, it is my guilty pleasure to have one just for home online use but in office I keep swapping SATA drives - Fusion drives, M2 SATA adaptors, etc. Don't start me on upgrades with external Thunderbolt devices, etc. Don't want the latest Mac Pro - unless I get it free or I win Lotto.ĭon't want to consider a Mac Pro (2013) due to its lack of upgradeability internally.
