Sorry I’ve been AWOL for so long. I love my dayjob & getting to do some really cutting edge projects. But it definitely cuts into my CustoMac’ing! A few people have posted messages about upgrading from HS > Mojave. Honestly, I’ve never been one for doing an upgrade (installing new OS over an old one). I always take the time to do a fresh install. Over the years, I seem to have less issues/problems this way. SO, having said that - here’s the lowdown on a new Mojave install.
Completely wipe disk in Win10 (using Diskpart) so that I have the equivalent of a new drive right out of the sales package. I did a fresh Mojave install using Unibeast v9 for 10.14.1 (downloaded from the App store & built using my 2017 MBP 14,3). Normal install instructions per macOS 10.14.x guides posted here.
When install is complete, run new MultiBeast for Mojave. First time through, used these options for my hardware configuration (FakeSMC could be optional fwiw):

Install. THEN, run MultiBeast again, selecting ONLY Drivers > Audio > AppleALC. Build > Install.
Next, I installed latest CodecCommander from RehabMan, using Kext Wizard (or your favorite kext installer), followed by fix permissions & rebuilt caches. Reboot.
Here’s the only hiccup: There seems to be some graphics-related issue in Mojave with both Preview (locks up when opening things like .png images), and FinalCut Pro (crashes on boot). To fix this:
That’s it… seriously!
- Enable IGPU in UEFI. Even though I have the RX580, enabling the IGPU seem to be key in resolving this issue.
-- UEFI/BIOS > Peripherals > Initial Display Output = PCIe1 slot
-- UEFI/BIOS > Chipset > Internal Graphics = Enabled
- Launch Clover Configurator - mount your boot drive EFI partition, then open your config.plist
- Navigate to Graphics tab > ig-platform-id and choose this option:

- (optional) Navigate to SMBIOS tab & re-select iMac18,3 - this populates more device information on this page.
- Save & close. Reboot.
What’s working? Everything (I think), just now starting to test. For sure:
--No issues with Preview locking up
--No issues with FinalCut Pro crashing on boot
...and now to start catching up on posts that I've missed! If someone has already figured this out for Mojave and posted, thank you! If not, hope this helps!!
Hi @BoomR , thanks for posting this. I think everybody was waiting for it
The only thing I can't get to work is the iGPU fix. When I enable the iGPU in the BIOS, Mojave won't start. At the Apple logo I get a "denied" symbol and it freezes.
I have almost the exact same specs as you do.
Thanks for the help.
