      This build is compatible up to Big Sur Beta
      Now Compatible with macOS 11 Please leave feedback with issues or w/o Comitted to Updating up to OS 11 Latest Release Notes
      Fixed Bluetooth and Wifi Stability Issues Improved Preformance and Power Managements Can Provide Files for Display Overrides Additional Patches for 4K Display updated for Big Sur if using unsupported wifi card disable it in bios use config.plist FIXED SLEEP WAKE BUG Exact same functionality as Catalina What Works / Does Not
      Everything works minus in-built mic Some displays may be detected as 40hz (working on fix) Notes
      Never tested USB C over Display Output, everything else works flawlessly USB devices eject on sleep (not really an issue) POST
      run sudo pmset -a hibernatemode 0 If no mouse, install all voodoo kexts using Kext Utility Description
      This esentially an ultra-simplistic version that is stable without the use of a deploy or complicated file installations and copies. You can easily view all the SSDT patches along with configuration files for the bootloader as they are all documented clearly in the files. This does include a copy of Clover, which of course I do not contribute to and am only responsible for the provided files, patches, and kext placements This guide provides a working setup with little knowledge of the topic and without "optimization" (because often they can break things). But, it is fully functional and preforms properly and is stable Make sure you are using DW1560 for wifi or else KP. If not using remove BRCM kexts from CLOVER>kexts>other. BIOS Setup
      Disable Secure Boot INSTALL (VERY IMPORTANT)
      Due to structural changes in the setup of apple's Big sur, this EFI cannot boot the installer it can only boot into a system / device that has already been created and setup. To do this, you need to install Big Sur to a virtual machine (lots of guides online) and then create an dmg of that system, and restore it onto your HDD using the 'dd' command There are various guides online how to get this virtual machine setup complete. You can then use the attached EFI folder to boot and use macOS big Sur You can use this video to show you how to get your macOS pre-installed onto your hard drive https://www.youtube.com/watch?v=HMU3nhcbWHw Boot Entry Setup
      Due to the fact this BIOS is locked down pretty heavily, reccomended to use Windows to find a free tool to add UEFI boot entries Messages and Facetime
      Gnerate your own Serials, Board Numbers, MLB There are various guides online to do this and as default they're set to essentially Null (Fakeserial) This is fairly straightforward and there is lots of external recourses, or you can contact me for support. Headphones and Audio
      All audio from speakers should work perfectly along with Bluetooth and USB audio no internal mic Credits

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

      News
      In light of the recent WWDC, we will begin testing the functionality of our EFI on macOS 11 for this device with the latest developer preview Version Info
      Features and Overview
      Now Compatible with 10.15.6 Please leave feedback with issues or w/o Comitted to Updating up to OS 11 Multitouch Trackpad Support 4K @60 Hz Fixed Bluetooth and Wifi Stability Issues Preformance and Power Management Additional Patches for 4K Display updated for 15.6 rev 1 Sleep Wake is functional for some models ----if screen glitches on wake or reopen lid. If this is a bother just disable sleep. This is issue is resolved in Big Sur Bugs
      Some models may experience screen split in half. If so disable. USB devices eject (external) No Internal Mic What Works
      Everything minus sleep issue above, internal microphone. (audio is fine, headphones / usb mic fine, just not laptop mic) POST
      run sudo pmset -a hibernatemode 0
      Description
      This esentially an ultra-simplistic version that is stable without the use of a deploy or complicated file installations and copies. You can easily view all the DSDT patches along with configuration files for the bootloader as they are all documented clearly in the files. This does include a copy of Clover, which of course I do not contribute to and am only responsible for the provided files, patches, and kext placements This guide provides a working setup with little knowledge of the topic and without "optimization" (because often they can break things). But, it is fully functional and preforms properly and is stable.
      Unsupported Wifi
      Make sure you are using DW1560 or 1820a for wifi or else there is a risk of KP. If not using remove BRCM kexts from CLOVER>kexts>other Styling
      This guide is designed to be literally as thorough as possible to appeal all types of users. It does not cover complex topics like undervolting etc etc only to provide a completely functional system
      Notes
      Never tested USB C except for charging, USB, works great (not sure about DispOut) 4K model has sleep wake issues occasionally, 1080P is fully functional BIOS
      Disable Secure Boot Disable Vt-d Recommended: Clean Install (Preinstall steps)
      Format a USB (16GB) as Journaled and then proceed to download the latest Catalina Installer Patcher Application. Download the latest Catalina installer from within the Patcher App, and select to download a new copy and install to your USB device Download the clover configurator application and mount the EFI of the USB partition, then copy the contents of the Files linked above to A new EFI Folder (that you create) within the EFI partition. ** This is because the App Store installers will often not download a full installer, just an truncated version that downloads the installer files from the interent while installing. Thus, they're not bootable from a USB as they're not complete. That is why you should use this method to make sure the installer is usable for bootable media.
      Boot From USB
      Use f9, copy EFI folder to efi partition of your usb. after installation complete copy EFI to your ssd. Boot Entry Setup
      Reccomend using windows to find a tool to add a UEFI bios entry to boot EFI/Boot/bootx64 Credits

      I'm transitioning from Clover to Opencore. I thought the process will be simpler but it turns out it isn't. I have created a bootable Catalina USB with Opencore but stuck at this error. I have attached my EFI and the verbose output. Anyone please provide some guidance please?
