Installed Catalina 10.15.4 (19E287) Vanilla with OpenCore on my HP Elitedesk 800 G2 Mini.

Everything is working (Wifi isn't but I'm using Ethernet anyway) but my second display.

I'm trying to get them both connected via DisplayPort as the only other output on my computer is VGA.

I've tried manually setting the framebuffer arguments, but I cannot get it to output to both displays. Yet if I unplug one and restart, it will use the other one just fine.

Any help would be greatly appreciated.

I'm about to try Catalina on a EliteDesk 800 G4 Mini, so I'm interested in your topic.  Did you have dual-display working in a previous version of macOS, or is 10.15.4 the first version that you installed?

I only recently bought my EliteDesk so I just went straight for Catalina.

I have got it working reliably, with one caveat being that I need to boot the system and login with 1 displayport cable plugged in and then once on the desktop, I can plug in the other monitor and it works just fine.

Other than that, system is stable and even the intel bluetooth works!

The thing that seemed to get the monitors working was disabling SIP, running ADGPFix and then re-enabling SIP.

My entire EFI (Opencore) can be found here. I'll do my best to respond faster and help if you run into any issues.

Thank you for your reply!  Congrats on your hack.  My EliteDesk specs are below.  Hopefully I have luck with UHD 630.

  • EliteDesk 800 G4 Mini
  • CPU: I7-8700T
  • Memory: 32GB DDR4
  • Display: 3 x DP
  • Wi-Fi: Intel (I know I'll need to change this if I want Wi-Fi)
  • Storage: 256GB M.2 NVMe SSD (1 M.2 NVMe slot is unused / still available and 1 standard SSD bay is unused / still available)

I got multi-display working with the DP ports (DP -> DVI adapters) on my HP EliteDesk 800 G4 Mini.  See this post.  Soon, I will be creating a thread that provides full details of the installation.

      I was previously using clover with Catalina and on that everything worked very good, now i shifted to Opencore everything is working on laptop except trackpad, from windows is searched that my trackpad is "Microsoft HID" and i have tried all the VoodoI2 kexts, seperately like VoodoI2CHID, VoodoI2CELAN, VoodoI2CSynaptics but trackpad won't work. Previously i was using VoodoI2CHID on clover and trackpad was working very fine.
      Kindly help me in that, a little help would be appreciated.
       I have attached my OpenCore EFI Folder

      So, I cheap out and got a $20 dw1820a for my laptop hackintosh - EliteBook 820 G3 macOS Catalina 15.5. Clover wouldn't boot or work properly, OpenCore works perfectly with some adjustment.

      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 everyone,

      I'm trying to install MacOS Catalina on the ACER C22-760 (i3 6100U, 520 HD)

      I did all the usual prep to install the system, especially as I've done hackintoshes with the same specs in the past.

      But after the moment it boots up, the screen goes black. So I decided to install the system booted in 0x12345678 and then fix the graphics.

      Long story short, with the installation done I've tried every single combination to fix the graphics and found out that:
      Booting with a 0x12345678, a 1080p monitor is detected, but obviously, no acceleration. Booting only with AAPL,ig-platform-id set to 19160000, the system boots with complete acceleration but no monitor attached into any framebuffer. About this Mac reports a 1280 x 1024 monitor (Found using Anydesk and ioreg remotely.) Changing the connector type to DP or HDMI, Internal o External, platform-id is useless. This system is getting me anxious. Because I don't find any fix for it.
      Someone can help me out? Love ya!
      PD: The system is an All In One with no HDMI port.

      Hi All,
       
      I'm trying to install Catalina via Clover, however, it hangs on ACPI errors. I've managed to reduce this from 6 to 4, but there's still some outstanding. 
       
      I'm thinking this may require DSDT patching to get by, but on the below information, how to do I gauge what I need to locate, and change values to?

      I've been lucky with past machines, rarely required a DSDT edit. The EC patch for Catalina has been applied.

      Model - Lenovo A540
      CPU - Intel® Core® i5-4258U (2.9 GHz)
      Chipset - Haswell
      Boot - UEFI Clover
      GPU - Intel Iris / HD Graphics 5100
      Resolution - 1920 x 1080
      Storage -  1TB hard drive
      RAM - 8GB
