An iDiot's Guide To Lilu and its Plug-ins

You mention that if I don't use a correct SMBIOS, which I'm assuming "should" be 18,x, I might see an unstable system. Right now, I'm not noticing anything out of the ordinary/unstable. System sleeps, wakes, restarts, shutdowns normally. Quicklook works. Able to play DRM videos via iTunes.

@osufella,

By using SMBIOS iMac14,2 MacOS will only use the CPU features and instructions sets of a 2013 Haswell based system (4th Gen CPU), if you switch to 18,1 MacOS will use the newer instruction sets and features of your 8th Gen CPU ... you should see slightly better performance as some tasks will be better optimised.

Despite I no longer need the guide because I switched back to Windows, jaymonkey I want to give you the thumbs up because this guide is awesome, pretty good and helpful even for veterans, good job

@vraiment,

Thanks for the feedback and thumbs up, glad you enjoyed it.

Cheers

@jaymonkey Great information and tutorial, thanks for your efforts. Really helpful!

Wondering if you could provide any insight on how DRM uses the iGPU vs. AMD or Nvidia.

Based on posts here, it seems most users who have AMD/Nvidia are able to get DRM working in Mojave but only by disabling the iGPU.

Doing that though breaks hardware acceleration for things like Final Cut. Enabling the iGPU/hardware acceleration disables DRM. We can’t seem to get both at the same time.

Any thoughts?

I've been investigating/fighting this over the past few days on my build. I'm running Mojave 10.14.2 and I was beginning to think it was a Haswell/HD4600 thing but it looks like you are having problems with this on a newer system as well. For now I just disabled the iGPU since I mostly do content consumption on this computer and don't need the video editing functionality. It still bugs me that it doesn't work the "right" way though.

Updated to 8.1, checked IOREG/VideoProc and the values returned are similar to what I showed before. Framebuffer matches as well.

I'm going to wait a few days to ensure everything looks good then I'll call this last piece of my build as complete.

Thanks!

@osufella,

I assume thats a typo and you mean iMac 18,1 ...

well, I went with 8,1 because it has the 8th gen processor which is what I have. I guess, why would I go with the 18,x since it lists as the 7th gen processor.

@osufella,

iMac8,1 is from 2008 and uses Intel Core 2 Duo CPU ... Which is a very old CPU architecture.

iMac18,1 is from 2017 and uses Intel i5 7360U CPU (Kaby Lake CPU) and is the closet match to your i3 8250K.
There are currently no iMacs that use Coffee Lake CPU's but Coffee Lake is just a Refresh of Kaby Lake and they work well with the iMac18,X SMBIOS.

As the guide states, you can use MacTracker to find the closest match.

Sorry, i was incomplete with my comment. I went with macmini8,1.

Clover Configurator shows as Late 2018 i7 8xxxx

@osufella,

I just noticed that you have AMD RX570 GPU so you will probably be better off using iMac18,3 as that system has dual GPU's (IGPU + AMD 570 or 575 or 580) make sure you enable the IGPU in the BIOS and set the AMD dGPU as Primary inject headless PlatformID for your IGPU using WhatEverGreen.

For more info see the Headless PlatformID instructions in the whatever green section of the guide in post #1.

Cheers

gotcha...makes sense...at some point that they come out with iMacs with 8th gen CPUs, we might go with an update.
