**********************************************************************************

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.

Background

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

A possible solution is here, but I am NOT offering any support for this.

macOS Installation

See macOS installation steps here See Known Issues here for additional installation steps that may not yet be included in my attached config files See CLOVER (UEFI) installation later in this first post

See BIOS configuration in attached BIOS configuration PDF document

See EFI and /L/E kexts in attached EliteDesk.zip archive See how I developed my installation methodology here See references here See instructions here for installing two M.2 2280 NVMe SSDs and one SATA HD / SSD

What is not working

Microphone port

What is not tested

USB c 3.1 port (I have partially tested the USB 3 functionality of the port and it seems to be working fine with the SSDT-UIAC.aml in the attached EliteDesk800.zip archive) Wi-Fi / Bluetooth (intentional since I have not yet replaced my Intel card). A possible solution is here, but I am not offering any support for this.



What is working

Everything not mentioned above Sleep / Wake Multiple displays with IGPU graphics acceleration, hot pluggable display ports and DP->DVI adapters USB 3.1 ports Audio (internal speaker and headphone jack) Ethernet Auto-sensing headphone jack automatically switches to internal speaker when headphones removed
