What are the steps here, what I am missing? I see people running 5770 with High Sierra on youtube, did they swap the video card just to get HS installer to run? Also found watching videos about 'boot screen-supported video card thingy' kinda dumb, but I guess that the thing, boot screen wont be there for me with 570, its MSI card. Or it isn't allowing me to get High Sierra because of video card? What if I put 570 in? I already have Mojave dmg, but that requires High Sierra installed. Also have MSI Radeon RX570 4GB card that I could use in that Mac.Ĭan someone please point me to where I can get High Sierra downloaded, so I can try and see what happens? I think that installer will also update the BIOS firmware on this MAC. I have 6core Xeon on the way, and already put in some ecc RAM.

But I don't see this option, and having trouble locating dmg installer for High Sierra. After your Mac Pro restarts, close the installer and go to SystemInformation and check if your BootROM is 00 now.
Download High Sierra installer from the Mac App Store, don't use hacked installs, torrents, etc. On a normal day I am a windows guy, so please go easy.īased on what I read, I should be able to install High Sierra (which will allow me to install Mojave later) on this Mid 2010 MacPro with included ATI 5770 card. The High Sierra installer will then ask you to perform a firmware update, shutdown your Mac Pro and do it.
