Yes, several folks here have reported successful updates.
Me too, just used the mini manual (front page 10.14.4->10.14.5) to update from 10.14.5 -> 10.14.6. All is working!

The Cinema Display's built-in USB hub is also a USB device that should be disconnected. Please connect keyboard and mouse directly into the rear USB 2.0 ports to rule out the hub.
Hey there!

Thank you for your assistance!
I am still waiting for an alternative USB3 card to arrive in the mail and will report back soon!

By the way:

Would it be possible to modify the „Disabling a GPU in PCIe Slot 2“ file from the first page to exclude the third x16 PCI-e slot instead of the second one?
I would be very thankful if somebody modified it!

By the way 2: I am currently evaluating the use of an EVGA nVidia Geforce GTX 780 CLASSIFIED graphics card in this machine. Worked out of the box on 10.14.5, including sleep and HDCP. Finally CRT resolutions via DVI-to-VGA at 100+Hz... :lol: I love my Sony Trinitron.
The RX 580 feels a bit smoother though.
Granted, it is 5 years younger...

Cheers,
schreiberstein

Does someone want to attempt this as a homework assignment? :) I can do it in a couple of days after returning from vacation. If you don’t get an answer by Monday, please remind me.

A CR-what?? I was about to throw a heap of sarcasm your way until I remembered I have a bunch of vacuum tubes in my preamplifier. :) And two turntables.

You may be able to skip MultiBeast and proceed as follows:
  • Mount EFI partition of High Sierra SSD.
  • Mount EFI partition of USB Install Disk.
  • Copy EFI folder from EFI partition of USB to EFI partition of High Sierra SSD.
  • Unmount the EFI partition of USB install disk and eject the USB install disk completely.
  • Open the EFI folder of the High Sierra SSD in Finder.
  • Add the following to EFI/CLOVER/kexts/Other:
    • AppleALC
    • Lilu
    • WhateverGreen
Reboot and see if you can boot directly into High Sierra without the USB disk.

If so, check:
  • Sound
  • Graphics
  • Bluetooth (if you have BT card)
  • WiFi (if you have WiFi)
  • Ethernet
  • USB ports -- try connecting some USB flash drives
  • FaceTime, Messages (requires WiFi/BT)
  • Sleep, Wake
  • Reboot, Shutdown
Make a list of any problems and let us know.

Thank you so much, will try asap. I have been attempting this with a normal HD and had issues with no EFI partition showing up in the boot menu so I had to boot from the USB every time. I will be reinstalling fresh to a SSD, is there anything I should know to prevent/fix this? I could not find anything through searching that worked.

Hey! Don‘t worry. It is not urgent or anything. You deserve a vacation more than anyone. ;) Take your time!

And yeah, I thought this CRT craze was bizzare as well before I actually tried one.
I do some fun stuff with DOS and Win9x and believe me... the experience is fantastic. Switching between resolutions without upscaling artifacts... 100Hz or 120Hz motion without blur...
Modern operating systems cannot compete with these insanely fast reaction times, neither the screens. You press a key and everything happens INSTANTLY. I might attempt to run Win98 on this board. A 7000 series Geforce card and a SoundBlaster connected via PCI-e to PCI should do the trick. What a time to be alive...

Cheers and enjoy your vacation!

Well if you want to give it a try use this. I have a sample efi there. Having zero panics on shutdown and startup.


What seems to make it work is the VirtualSMC instead of the FakeSMC.

EDIT: Upgraded to 10.14.6 and no issues.
Actually, it works with 10.14.6, FakeSMC, and the latest Clover release (5028) too!

This is going to sound very counter-intuitive, but if the only Thunderbolt device you have at the moment is the LG 5K Thunderbolt Display, then please try the following:
  • Mount EFI partition of Mojave SSD and temporarily delete or move-out the file:
    • CLOVER/ACPI/patched/SSDT-Z390-DESIGNARE-TB3HP-V4.aml
  • BIOS --> Enable CSM Support
Reboot. Any change in behavior?
  • Does screen go black and stay black?
  • Can you hot-plug the LG 5K?

Now the screen goes black and stays black no matter how many tries. It also made the resolution for clover and macOS boot weird. I still cannot hot-plug the LG 5K. The other thunderbolt device I have is an Apollo Twin MkI via TB2 adaptor. Before changing these settings you had me test, I was able to hot-plug the Apollo Twin no problem. The LG 5K was the only issue. Now it doesnt even read the Apollo Twin at all, either.

Okay, let’s undo both of the changes. Those changes help with eGPUs in external Thunderbolt chassis, but apparently do not help with 5K dGPU connections.
