In this thread, I have fully documented the installation of macOS Catalina on my HP EliteDesk 800 G4 Mini. It is a PERFECT HackMini8,1 and is running very well for me without any issues. I hope this documentation helps you to install macOS on your hack. Please leave feedback if you think there is anything I can improve and let me know if you have any questions.
This is my first "modern" hack supporting UEFI and my first hack using Clover "on-the-fly" patches. My previous hacks
Laptop: Thinkpad T61 / Nvidia NVS 140m Laptop: Dell Latitude E6410 / Nvidia G3100m Desktop: Gigabyte G31 / GeForce 9600 Desktop: Biostar TH55HD / Sapphire Pulse RX580 (Google "Catalina Biostar TH55HD" and look for user name deeveedee)
are all perfectly running Catalina and I patched them all "manually" - all DSDT patches applied with MaciSL with virtually no Clover on-the-fly patching and all booted Legacy Clover. This UEFI hack was MUCH easier and took about 20 hours vs. a combined hundreds of hours for the old hacks. I wanted a hack that was a little more future proof and I think this is it. I hope you enjoy this as much as I am enjoying it. It is a perfect MacMini8,1.
My system specs
HP EliteDesk 800 G4 Mini (I7-8700T / UHD 630 / Q370 Chipset / 32GB DDR4 RAM) 3 x DP Ports (connected to monitors using DP -> DVI adapters) 6 x USB 3.1 1 x USB Type-C 3.1 2 x NVMe SSD (M.2 PCIe x4 2280/2230 combo ports) 1 x SATA6 SSD 1 x Intel Ethernet RJ-45 Conexant CX20632 Audio Codec Unsupported M.2 PCIe x1 2230 Intel Wi-Fi (currently disabled in BIOS). I may replace this with Brcm, but am using only Ethernet (IntelMausi) for now.

So I have some less powerful hardware, that's why I'm installing High Sierra in 2020. Anyway, I'm trying to boot from the USB and I get the following errors:
00:000 00:000 OCB: Missing DMG signature, aborting 00:585 00:585 OCB: LoadImage failed - Unsupported That's it. The logs begin and end there. The rest of the file is zeroes.
Bootloader: OpenCore 0.5.9 Release
Note: I used SSDTTime to make the DSDT dumps for this exact computer
Intel Core i3 (Haswell)
An Intel VGA-Compatible Haswell iGPU
An nVidia Geforce 920m GPU (part of the reason for installing High Sierra)
USB: Intel 8 Series USB xHCI HC
SATA: Intel 8 series SATA Controller
If you need more details, here's my laptop https://www.asus.com/Laptops/X540LJ/ . I have the 512GB version with 4GB of RAM
I found a lot of forum posts about people having the same error, except nothing solved mine. Also, I haven't found anything online about the error with the Missing DMG Signature.
EDIT: If anybody needs my config.plist, feel free to ask for it and I'll happily post it
After hearing that OpenCore is so much better than Clover, and that it will probably be able to boot Big Sur before Clover does, I decided to take the jump.
Running Catalina 10.15.5 18F101 with OC 0.5.9.
So far I like the result. The OS feels faster, boots faster.
And absolutely everything works (sleep, network, etc...)
So, that's it? Is there anything else I have to do?
Hi guys, this thread is to show you a new and open source app, created by me, that I called TINU:
The name means: TINU Is Not #####, the U refers to a popular software that is used to create macOS hackintosh installers (that for good reasons is banned on this forum), but the aim of the name is to explain that this app is a totally different thing from that software and works in a totally different way.
This app basically is a graphical interface for the createinstallmedia executable that is inside the macOS and Mac OS X installer apps, it is capable to create a bootable installer completely vanilla like what you do using the command line method, and also this method is recommended by apple itself. In addition to this, this app provvides to you simplicity and flexybility, and lets you to avoid most of the steps needed with every other app.
TINU allows you to create easily a bootable macOS installer without messing around with command line stuff and without using disk utility, all you need to do is use the app and then install clover on the usb drive once TINU has finished or leave it as is if you want to use it on a real Mac.
- Simple-to-use UI that allows you to easily start the bootable macOS installer creation process.
- It can work with every macOS installer app that has the createinstallmedia executable inside its resources folder (including also beta and newly released installers).
- You can use any erasable volume that is at least 7 GB of size (10+gb if you use catalina or newer versions, if the volume's drive is not in GUID format, TINU will re-format it accordingly).
- Can work with the Mac OS recovery system, so you can create a bootable macOS installer from the macOS installer itself or from the macOS recovery partition, and you can use TINU to install macOS, too.
- 100% clean: The bootable macOS installers created with this tool are vanilla, just as if you created them using the command line "createinstallmedia" method in Terminal.
- Open Source: You can verify what this program does on your computer and you can create your own version by downloading and playing with the source code.
- Does not require any special preparations. Just open the program, make sure you have a USB drive plugged in and have a macOS installer app on your disk.
- No need to use Disk Utility. TINU can format your drive or partition for you.
- Integrated EFI partition mounter tool.
- Autaomated Open Core and clover EFI folder isntaller
- Works using the latest versions of macOS and will also support newer Mac installers out of the box without requiring an update.
Features that are planned for future versions:
- Support for other languages, at least Italian.
- A computer that runs Mac OS X Yosemite or a more recent version (Mac OS X El Capitan is required to use TINU in a macOS recovery or installer).
- A drive or a free partition (on a drive which already supports GUID) of least 7 GB that you want to turn into a macOS/Mac OS X installer.
- A copy of a macOS/Mac OS X installer app (Maveriks or newer versions are supported) in the /Applications folder or in the root of any storage drive on your machine (excepted the drive or volume you want to turn into your macOS install media).
