Overview

Almost everything works properly and is very stable:

  • audio (onboard, via dGPU's DP, and via Fenvi BT)
  • nightshift
  • App Store and iServices
  • CPU PM
  • wifi
  • bluetooth
  • handoff
  • continuity
  • instant hotspot
  • DRM (except for Apple TV)
  • Intel Quicksync
  • sleep (HDR toggles itself on sometimes upon resume which sucks because it looks like garbage on my monitor when not viewing actual HDR content; haven't tried to fix yet); wakes up from sleep via BT keyboard or mouse quickly and reliably
  • restarts/shutdowns
  • recovery
  • NVRAM
  • extra sensors and fan speed controls via apps
  • thunderbolt 3

Editing config.plist

Inside the EFI/OC folder on your installer open config.plist and edit/populate the following fields:

PlatformInfo -> Generic -> MLB
PlatformInfo -> Generic -> ROM
PlatformInfo -> Generic -> SystemSerialNumber
PlatformInfo -> Generic -> SystemUUID

You can generate the MLB/Serial/UUID serials with GenSMBIOS. Use option 3 and enter iMac17,1 when asked for the type of SMBIOS to create. If you need to change the model in the future you also need to re-generate a new set of serials, UUID and USB portmap.

Put your ethernet mac address in the ROM field without semicolons. Fixing this post-install is also an option, but is important so don't skip it.

For more information on setting up OpenCore please refer to this very well written guide that has helped realise this very setup.

Please use ProperTree to edit the OpenCore config.

BIOS Configuration

  • optimized defaults
  • storage to AHCI mode
  • enable USB powershare
  • set preferred graphics to AMD (if using dGPU) or auto
  • disable TPM (should be by default)
  • disable Secure Boot (should be by default)
  • enable Thunderbolt 3 and set security disabled if you have an add-in card

The rest of the recommended settings are already the defaults used by this BIOS. DVMT is 32MB for the iGPU and setup doesn't expose a means to change this. I modified it via setup_var and the modified GRUB shell while trying to get an iGPU-only setup working with a 4k display.

UEFI Modifications

These are MY settings given BIOS version 1.6.0 and board 07T4MC. You need to check these offsets and make sure that they're correct for your machine before trying to change things.

Dell has not changed the offsets for MSR2, DVMT pre-alloc, or Above 4GB MMIO so far in any BIOS release that I've extracted and analyzed from 1.0.0 through to 1.6.0. That said, it is unwise to assume that this will continue to be the case and with each release you should extract the firmware and ensure the locations are still correct prior to making changes with modified GRUB shell.

This EFI will not work unless you make all of the UEFI modifications. If you're not up for that, you'll need to add npci=0x2000 to your boot args, enable KernelPm and AppleIntelCPUPM in your config.plist.

Post-install

Sleep

Sleep is working as it should. It will fall asleep automatically after a while. Waking up the machine can be done with a bluetooth or usb keyboard/mouse. Apple has removed the slider to control this but it does go to sleep on its own. Manual sleep also works, it takes about 30 seconds. Hibernation is disabled by default on desktops. For good measure lets disable stand-by and auto power off.

sudo pmset -a standby 0
sudo pmset -a autopoweroff 0

If you don't plan on enabling hibernation you can delete the sleepimage to regain some space. Delete the file and create a folder so macOS can't generate the sleepimage file again.

sudo rm /var/vm/sleepimage
sudo mkdir /var/vm/sleepimage

Power Nap is enabled and doesn't cause any issues with sleep. Not sure if it actually works though (doing Time Machine backups while sleeping, etc). Don't want Power Nap? Disable it while you're here; sudo pmset -a powernap 0

Verify the settings with pmset -g.

Power Management

CPU power management works fine as does sleep.

USB Portmap

I created an injector kext using hackintool which you can use to save some time. One port had to be disabled in order to get down to the 15 port limit. You could just as easily set a USB 3.0 port to USB 2.0 to get to 15 ports if you prefer. USBMap.command and USBToolbox are other ways to create injector kexts and/or SSDTs for your USB mapping. If you run a TB3 controller with an LG Ultrafine it really won't matter since you'll have a USB 3.1 type-A port on the PCIe adapter plus two type-C ports on the back of the display (on their own controller).

If you'd like to create your own port mapping follow these steps:

  1. Open your OpenCore config and set Kernel -> Add -> 5 -> USBPorts.kext to disabled and enable Kernel -> Quirks -> XhciPortLimit.
  2. Reboot.
  3. Open Hackintool and go to the USB tab, select all ports listed and remove them, then click the refresh button.
  4. Plug a USB 2 device in every usb port.
  5. Plug a USB 3 device in every usb port.
  6. Remove anything not green, you should be left with 16 green ports.
  7. Make sure all the HSxx ports are set to USB 2, SSxx ports are to USB 3, and internal/proprietary ports are set to internal (255).
  8. Remove one port to get down to the 15 port limit (or set a USB 3.0 device to use a USB 2.0 personality).
  9. Click on the export button and place the resulting USBPorts.kext in the OpenCore kexts folder (overwriting the existing one).
  10. Open your OpenCore config and set Kernel -> Add -> 5 -> USBPorts.kext to enabled and disable Kernel -> Quirks -> XhciPortLimit.
  11. Reboot.

dGPU

The current config assumes you have an AMD GPU and a Xeon E3-1225v5 with the Intel HD P530 iGPU in headless mode. configured to drive a display.

If you don't plan on using the iGPU at all (i.e. no display connected) you can delete the whole PciRoot(0x0)/Pci(0x2,0x0) section and WhateverGreen should automatically configure it as computing device. It can do video encoding/decoding and such. You will also need to change the BIOS and make the dGPU the primary video card for encoding/decoding to work.

iGPU

The Intel HD P530 that my Xeon has is not natively supported and requires spoofing a supported device ID.

The real device ID 0x191D will not allow hardware acceleration and needs to be adjusted to the nearest natively supported option that shipped in a real Mac.

After comparing the Skylake CPUs which Apple offered to my Xeon on Intel's Ark I decided that 0x1912 would be the closest device ID.

I setup the framebuffer as follows within the device properties section:

  • AAPL,ig-platform-id
    • 0x19120000
      • 00001219
  • device-id
    • 0x1912
      • 12190000

With these settings I had full hardware video acceleration and was able to view DRM-protected content (FairPlay 1.x and FairPlay 2.x/3.x). FairPlay 4.x for Apple TV is not working for me and I'm not sure why yet. I'm guessing it's because my system doesn't have a fully supported wifi/bt setup and my USB wifi adapter is seen as an ethernet interface.

I sold my RX580 to quiet the machine, reduce power consumption, and because my 4k displays look way sharper over DP when using the iGPU vs the RX580. I have no idea why this seems to be the case but it's enough of a change that I've switched to solely integrated graphics. If you run the iGPU by itself use 0x191B for the device ID.

SMBIOS

It's best to use a model that matches your processor as closely as possible.

The iMac17,1 SMBIOS is recommended for Skylake desktops if you have an iGPU+GPU combo or just the iGPU.

The iMacPro1,1 SMBIOS should be used if you only have a dGPU. These two options are the only Macs that shipped with Skylake CPUs.
