[Success] Mojave on EP45-UD3L

[xRotorHead]

Successfully built a hack of macOS Mojave 10.14.2 on this (old but not dead) Gigabyte EP45-UD3L (rev 1.0) motherboard with a Core2Duo E8400 CPU and GTX 650 Ti GPU. It was done with plenty of trial and error, but it’s now virtually flawless. Here’s my lessons learned.

Presumption you are familiar with the standard hack installation processes.

Making a working Clover bootloader was the first challenge. None of the Unibeast bootloaders would work. So I did this:

1. Build a Clover USB bootloader
2. Delete everything in its EFI partition.
3. Copy the EFI folder and boot file from the attached UD3L-EFI.zip below and paste into the USB EFI partition.​

This zip contains the appropriate DSDT, non-UEFI patches, fix for the I/O Errors, and config.plist edits for the EP45-UD3L (rev 1.0) with a GTX 650 GPU.

Then, the machine will boot and most of the installation goes as standard…until about the 3rd or 4th reboot in the installation phase where it would panic/reboot/loop or get stuck in an endless black screen with apple logo and empty progress bar. So now you’ve got to:

4. Replace the com.apple.telemetry.plugin from 10.13.x into the System/Library/UserEventPlugins.
Version 10.13.6 of the TelemetryPlugin.zip attached below.​

I’m sure there’s a terminal command to do that, but for simplicity I just connected the drive to another mac and replaced this file. And while you’re at this point:

5. Copy/replace everything from the attached LE.zip into Library/Extensions.​

Upon doing these 5 steps, put the drive back in the machine and the installation would resume, complete and reboot to a fully functional macOS Mojave 10.14.2 including audio, sleep, full GPU acceleration/Metal support.

This old motherboard is working pretty well despite its prehistoric status. Not a lot of guides out there for this aging hardware and the newer equipment is so much easier to work with, but it’s just not as challenging. I love doing hacks on this hobby horse of a motherboard. Hope you have fun with it as well.

I didn't think there were any Nvidia drivers that supported metal yet?

The GTX 650 has native support, no additional Nvidia drivers required.

Dang, I wish I would have remembered that before!

I've been lurking around holding out for the web drivers.... when I could have stolen my son's 660?? And now I have to sit at work all day thinking about it...

Thank a million... I still have this motherboard

Any luck with 10.4.4?

Any luck with 10.4.4?

Yes - it's the same like 10.14.2, but only this Part:

"4. Replace the com.apple.telemetry.plugin from 10.13.x into the System/Library/UserEventPlugins.
Version 10.13.6 of the TelemetryPlugin.zip attached below."

It worked for me.

wow, thats an amazing piece of craftmanship to get such an old rig to run Mojave. I am trying to get 10.13.6 to run on my old C2D E8400 on an EP45-DS3R with an NVidia 9800 GTX. Sadly I get a reboot after being 90 seconds in the System...

Does this methord works on any lga 775 motherboard?
I have a core 2 quad 9550
Gigabyte g41 motherboard (lga775)
Gt 610 2gb

Quick question - on the clover boot loader - UEFI or legacy mode?
