      **********************************************************************************
      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.

      Hi,
       
      I followed the OC guide, and installed Catalina 10.15.5 on my PC.
      The installation went very well. Most parts also work well after I login to the desktop except the following
      issue:
      Each time I tried to log back into the desktop from sleep, I would get a black screen very shortly after I entered the desktop.
      And black screen will last from a few seconds to a few minutes, no exact lasting time.
      Keyboards and mouse are still working during black screen, I can see the operations after the monitor works again.
       
      It connects LG monitor via DP port and I tried to modified the dp version between 1.2 and 1.4, got the same issue.
       
      Attached my entire OC folder, I'm so appreciated if someone could help me check it out, or tell me which part I should focus on.
       
      Thanks in advance!
       
      P.S. Here is my PC summary: Dell Optiplex 7060 MFF

      Hey all, hope you’re well :-)
       
      Writing this from a phone so apologies in advance for formatting errors etc.
       
      I’d like to build / am in the process of building a new machine. I started, then my mobo died and had to be rma’d and that put things on hold for a while..
       
      Now things are are back on track here’s what I’m looking at. 
       
      I would like the system to boot Mac OS for music etc and as main / general os, Windows for gaming and Linux for development etc.
       
      Heres the hardware I’m looking at - when I was looking at this previously I had set it up with clover but am definitely looking to go opencore this time around.
       
      Gigabyte Aorus Pro / Aorus Pro WiFi 
      Intel 9700k
      Corsair 650w PSU
      CoolerMaster ML240L
      MSI Air Boost Vega 64
      970 evo 1TB (Mac)
      Intel 660p 512GB (Windows)
      Crucial BX500 120GB (Linux)
      2TB Barracuda or WD Blue (Storage)
      Fenvi FV HB-1200 WiFi / Bluetooth 
      Aerocool Cylon Case
       
      I wanted to rival next generation games consoles and get a newer GPU but I will not be using Catalina due to the removal of 32 bit support. Therefore I think the vega is about as good as I can get with Mojave, and it will still work fine in windows for gaming etc. 
       
      What are your thoughts on the above hardware ? 
       
      Hack/Mac-able? / With opencore ?
       
      Any Issues I may encounter ?
       
      I think I have most of the drivers / kexts for opencore together already but I’m obviously unable to progress with the ssdt files without the hardware. Wanted some advice on whether or not it’s doable before I splash the cash 
       
      I’ll also add to this thread / move it appropriately as the build progresses, hopefully smoothly
       
      peace & thanks in advance :-)

      Now you can start the instalation without problem (I guess).
       
       
      How install
       
      UEFI Setup Configuration and Installation

      UEFI configuration
       
      - Shutdown and insert the flash.
      - Power on with DEL pressed to enter BIOS setup.
      - Change value: Periphelrals - Initial Display to IGP
      - Change value: Periphelrals - USB Configuration - XHCI Hand-off to ENABLE
      - Change value: Chipset - VT-d to DISABLE
      - Change value: Chipset - Internal Graphics to ENABLE
      - Change value: Chipset - DVMT Pre-Allocated to 128M
      - Save & Exit Setup
       
      - Now, hold the F12
      - In the list, select your flash drive.
      - It will show twice. One with UEFI prefix and another without.
      - Select with UEFI prefix. Ie.: "UEFI: Sandisk Cruzer"
       
      The installer will start. 
      
      Format destination disk

      Format the disk with GUID partition mapping and name it "HD".

      - Select Disk Utility in the list, then press Continue.
      - Click in View, then "Show All Devices".
      - Select the destination Disk, then Erase.
      - Name: HD, Format: APFS and Scheme: GUID Partition Map

      Close Disk Utility.
      
      Select "Install macOS", then Continue.
      Follow instructions in screen.

      After install

      After first part install the system will reboot.
      
      The second part of the installation will begin. This will take 16 minutes.
       

      Post installation

      Install bootloader
       
      When the second part of install finish, the system will reboot again.

      After performing the user initial setup and go to the desktop, you need to install Clover on internal disk.

      Open the Clover installer inside flash drive that you copied before.

      Use same options above but choose the system partition this time.

      Now you need to replace the EFI folder inside your destination disk EFI parittion, with EFI folder inside flash card EFI partition.

      If the flash drive EFI partition of your destination disk or flash drive is unmounted:
      Mount with terminal "sudo diskutil mount /dev/rdiskXs1". To know what X is, use "diskutil list", most likely is 0 for destination disk and 1 for flash drive.
       
      Then, eject the flash drive.
       
      Last step
       
      Move all Kexts from EFI partition to /Library/Extensions, with those commands in Terminal:
      sudo cp -R /Volumes/EFI/EFI/CLOVER/kexts/10.14/* /Library/Extensions/ sudo chmod -R 755 /Library/Extensions sudo chown -R root:wheel /Library/Extensions sudo kextcache -i / Restart the system.
       
       
      It's done!
       
       
      Updates
       
      System update 10.14.6
       
      - Download and open latest CloverConfigurator
      - Open Mount EFI and click in Mount Partition in EFI Partitions list
      - Click in Open Partition that appears
      - Go to EFI -> CLOVER
      - Backup config.plist and ACPI folder to desktop
      - Go back and delete CLOVER folder
      (If you restart now you can't boot in macOS - DON'T RESTART)
      - Download latest Clover and install (link and config above)
      - Replace config.plist and ACPI folder from your desktop
       
      - Update Lilu.kext, AppleALC.kext, WhateverGreen.kext, HWSensors kexts (FakeSMC, ACPIMonitor, IntelCPUMonitor, ITEIT87x) in /Library/Extensions/
      - Run:
       
      sudo chmod -R 755 /Library/Extensions sudo chown -R root:wheel /Library/Extensions sudo kextcache -i /  
       
      - Install macOS Update 10.14.6 and restart
       

       
      And last but not least
       
      I would like to thank the following community members, by making these dream possible:
