[Success] b1's "Mac Mini Killer" with macOS Mojave: i7-8700 | Gigabyte Z370N | RX560 | 16GB RAM

Interesting! Do you have a good learning source about setting up OpenCore correctly?
TIA

There are a few guides out there but none I'd recommend over any other. Yet. Most seemed aimed at the 'advanced user' who understands code and xml. Not good for most of us who just want it to work. 'Beta' software means anything could change as things are refined, but it's certainly going to be the way forward.

I just read the official documentation - and I would also recommend taking look at OpenCore Configurator from the same people who publish Clover Configurator. It's still in a development stage itself, however it does show all the processes in a very visual way, and that can be useful, especially how 'paths' and 'quirks' are used. Even if you use a plain text-editor to create your config.plist.

@UtterDisbelief Great stuff and thoughts about OpenCore, thank you!

May I ask - what's the quick one or two lines of why OC will be the way forward?

Do you actually notice something on your build that feels better or more native or something like that?

I'm trying to decide if it's worth tinkering with.

Thx!

OpenCore and Clover are developed by the same team and at some time in the relatively near future they will drop support for Clover in favour of OpenCore.

Oh! - wow
Ok - That is a pretty major detail I'd totally missed.

Hey, guys! I did it.Running latest Catalina 15.2 on an external SSD.

Sidecar(amazingly good even via WIFI), iMessage, Hevc support in Videoproc for rx580 and all other functions are working or at least they seem to work, but... Yeah, there's mostly "but" involved when you talk about hackintosh.

It seems that FCPX and Compressor only utilize a tiny bit of GPU and CPU power(I'm talking about 20-30% or even less according iStat Menus).

So what I did step by step:
1.Cloned my current 14.2 Mojave to an external ssd.
2.Took @b166ar 's latest(Aug 13) EFI which he mentioned was Catalina ready(it is) and replaced mine keeping my original config.plist.

I tried to update to the latest Clover, but it seems that I'm not enough knowledgable and it simply wouldn't boot.
3.Replaced files according this post for more USB power

Proper USB Power
Put both the files in Clover->ACPI->patched
Based on Rehabman's guide for USB Power

Now I can charge my iPad after this.

If I remember correctly @b166ar 's fixed it in his latest config.plist without these patches and also switched to to iMac 19,1 SMBIOS, but I've decided to stick with iMac18,3.

4.Used kexts updater and updated them to the latest versions.
5.Booted into 14.2 with new EFI, and simply went through install from AppStore.
6.After setting everything up in Catalina realized that rx580 doesn't appear in Videoproc , fixed it according this post

Found the solution - at least on my hardware with 10.14.5.

Set Graphics>FB Name to 'Orinoco' (available from drop-down list).
Set Graphics>Inject ATI

View attachment 409127

and added dummy HEVCEnabler.kext to EFI's Others folder.

So everything now looks like in the picture above.

I thought that problem in FCPX 10.4.5 so updated it to 10.4.8 and to the latest version of compressor - nope.

Changed SMBIOS to 19,1 - no effect.

Will do more tinkering later for sure, glad that I can do pretty much everything while having alongside perfectly working 14.2 completely intact.

I will provide my OpenCore configuration.
OpenCore for ACPI patch from https://github.com/daliansky/OC-little
I hope the acidanthera development team can solve the igpu problem at an early date.

Good news guys! I've managed to boot with F12 bios. It is easier than you think. Here is a simple step by step guide. 1. Make a boot USB flash drive with your current EFI folder. 2. Download bootx64.efi and copy it to EFI/Boot/. This is some kind of alternative bootloader that starts with the command line. Here we will modify hidden BIOS settings. 3. Update BIOS to F12 (only F12!) 4. Reboot and hold F12 to boot from your USB Flash drive. Now you should see this command line. 5. Now enter

setup_var 0x5A4 0x0

setup_var 0x507 0x1

Reboot from your primary drive. You Hack should boot normally. But don't forget to set up your BIOS settings. Looks like we will need to do this every time after trigger «Reset to default settings» option in BIOS. P.S. If you are interested in the details: 0x5A4 is CFG Lock option in BIOS 0x507 is System Time and Alarm Source option This codes are not static and can be changed in future updates. You can use this guide to find this code for future versions of BIOS.

Thanks for your hard wokes. I followed your steps but the command line return "offset is out of the range",do you know what's wrong with this

JohnSu, Hi!

I became interested and I updated the BIOS to F12. I did everything according to the instructions. My screen also says: (offset is out of the range).

I was able to boot from F12.

Works good!
