Wow….okay, this has been an adventure. By the way: I never did succeed in making a working, USB installer for Mojave. What was wrong? <\/p>\n
So a few years ago I was bored and decided I wanted to fiddle with a Mac computer. In 2018 I paid $300 for a 2009 Mac Pro “Nehalim”. From the web: “The Mac Pro “Quad Core” 2.93 (Early 2009\/Nehalem) is powered by one 2.93 GHz Quad Core 45-nm Xeon W3540 (Nehalem) processor with a dedicated 256k of level 2 cache for each core and 8 MB of “fully shared” level 3 cache.” Anyway, that’s the computer. It came with a 500 gig SATA drive and arrived with a whopping 6 gig of RAM. I let the thing sit in a corner until recently (August, 2023). I finally set the thing up and did some upgrades. I upgraded the RAM to 32 gig, installed a Nvidia GX 680 GPU and flashed the thing so as to be compatible with Mac (making it Metal compatible), and even bought a new processor (6 core, not yet installed). With the GPU upgrade I was able to install Sierra, High Sierra, and Mojave natively….without any patching. All went fine until I tried to install Mojave.<\/p>\n
So, I have access to mutiple releases of Mojave via a bit torrent site – yeah, I said that right here in front of the world. Anyway, I downloaded the most recent release and attempted to install Mojave via a USB installer. I had divided my hard drive into two, equally sized 250 gig partitions and was working from High Sierra. I copied the Mojave installer to the Applications folder on High Sierra and copied the commands from the Apple web site to make the Mojave installer.<\/p>\n
The first problem I ran into with the installer – and it was minor – was that it was not connecting to the Internet. I had to go up to the Network utility and choose the port where I’d plugged in my ethernet – no big deal but this was something I’d never run into, before. Too, I opened the terminal and changed the date to 01\/01\/2018 because I know from experience that these installers are fussy about dates. The date on the computer has to roughly coincide with when an installer was released, I had learned from experience.<\/p>\n
So with these minor things all squared away I proceeded to try the install. Over and over and over again I got the following error:<\/p>\n
Installing macOS Mojave on this Mac requires that all graphics cards have Metal support and that FileVault is disabled<\/strong><\/p><\/blockquote>\n
Well, according to the System Report on High Sierra I had Metal support, and, I had disabled the FileVault. So, what the hell was going on?<\/p>\n
I Guess This Is The Answer<\/h2>\n
“Known and unresolved problem since the first betas of Mojave, GTX 680 and other Kepler cards are not recognised as METAL supported GPUs when booting from USB with a MP5,1 and you have to clean install from macOS to a second disk.<\/p>\n
This problem is documented on the notes:”<\/p>\n
