This guide is a work in progress and will be updated as I refine the installation.
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 SMBIOS MacModel MacMini 8,1 Unsupported M.2 PCIe x1 2230 Intel Wi-Fi (currently disabled in BIOS).

Known Issues and their solutions
(Solved. Cycle power on the new display) A new display may not be detected if the new display is plugged into an unused display port while the HP EliteDesk 800 G4 Mini is sleeping. Solution is to cycle power on the new display after waking the EliteDesk 800 G4 Mini. Cycling display power on the newly added display causes displays to be re-detected. (Solved. Problem resolves itself after a few boot cycles) After applying the Catalina 10.15.5.02 supplemental update, Catalina booted to a single display. After a few boot cycles, multi-display operation was restored to normal. (Solved and included in the attached EliteDesk.zip archive) Unable to upgrade from 10.15.4 to 10.15.5 when using IntelMausiEthernet.kext. Solution is to switch to IntelMausi.kext (Rev 1.0.2 here). (Solved and included in the attached EliteDesk.zip archive) Some USB devices were not recognized. My SSDT-UIAC.aml was incomplete and did not specify all required USB port types (missing SSxx ports). The attached EliteDesk.zip archive includes this fix. (Reported this as a possible Clover issue - no solution yet) Clover boot loader may default to Recovery volume after a normal shutdown. Work-around is to select your normal macOS volume. This may only happen when Clover is configured to boot LastBootedVolume and may be "fixable" by explicitly setting a boot volume (haven't tested this). (No longer observed) At least one display blanks (sleeps) when plugging / unplugging USB device (observed in front USB 3.1 ports). Display wakes immediately on keyboard and mouse activity, so this is a minor issue but may be indicative of another issue. (Solved - this is a BIOS setting and requires no macOS changes) Safari has problems loading insanelymac web pages after sleep / wake. I suspect that the problem is with the embedded video on the pages. Also observed video problem in AppStore after sleep/wake. Console: VideoDecodersUnavailable. Solution is to enable Intel ME in BIOS. (Solved and included in the attached EliteDesk.zip archive) Display does not fully wake after resuming from sleep (needs an extra mouse or keyboard stimulus to fully wake). Solution is to change boot arg darkwake=0 to darkwake=2. Other values of darkwake may work as well, but this is the first I tried and it worked. (Solved and included in the attached EliteDesk.zip archive) -disablegfxfirmware boot arg is not required with WEG. I inadvertently left this boot arg after I encountered an endless gfx firmware update boot loop while working on my FB patching. This boot arg is no longer necessary after completing FB patching with WEG. (Solved and included in the attached EliteDesk.zip archive): Sometimes, CMOS time is lost on shutdown or restart. Solution is to enable Clover's Apple RTC fix in config.plist. (Solved and included in the attached EliteDesk.zip archive) headphone jack doesn't work. Solution is to change HDEF layout-id to 28. (Solved and included in the attached EliteDesk.zip archive) System freezes on wake from sleep because of a kernel panic related to hda-gfx (my system does not have HDMI and my DP->DVI adapters do not drive monitor speakers). Solution is to add No-hda-gfx property to HDEF as described here. This property is recognized as a Lilu flag and prevents loading hda-gfx. (Solved and included in the attached EliteDesk.zip archive) Device (PMCR) is not defined. Solution is a SSDT that "injects" the missing device. (Solved and included in the attached archive) eficheck is loaded (not sure why this is bad, but may be a privacy issue - see here). Solution is to add updated EFICheckDisabler kext that include Q370 chipset. See here.

We're all here to have fun and learn from each other!
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
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!

This thread for installing Catalina on the Dell Latitude E6410 WITH NVIDIA GRAPHICS (BIOS A17, NVidia 3100m) will help you install a fresh installation of Catalina on your Dell Latitude E6410, it will help you upgrade from 10.15.2 to 10.15.x (if you originally installed Catalina from this thread) and it will also help you upgrade from Mojave 10.14.6 if you have already installed Mojave by following the instructions here. The instructions in this first post assume that you are installing Catalina in an APFS container. If you are curious about the evolution of this solution and how sleep/wake was solved, review the Mojave installation thread.
Important: This Thread is NOT intended to help you install macOS on a Latitude E6410 with Intel HD Graphics (without Nvidia graphics). The DSDT attached to this first post (in E6410-Catalina.zip) is VERY SPECIFIC to the Nvidia graphics implementation and has not been edited for HD Graphics - there are elements required for HD Graphics that are missing from the attached DSDT and there are DSDT mods that have not been tested with HD Graphics. Also, the kexts attached to this first post are specific to a Broadcom Wi-Fi card which must replace the original Intel Wi-Fi card.
This first post will be modified to reflect lessons learned and to reflect the most current working state of my Latitude E6410 (with NVidia 3100m discrete graphics) running Catalina. Issues, observations and performance tips are recorded toward the bottom of this first post. My recommended CLOVER configuration is specified toward the bottom of this first post.
*** If you want help with your installation, please post your issue along with problem reporting files generated using @black.dragon74's problem reporting tool. Google 'GENERATE PROPER PROBLEM REPORTING FILES black.dragon74' to find it. ***. If Catalina's Read-Only protections block your installation of black.dragon74's gen_debug script, please copy the attached gen_debug script to your Desktop, change script properties with the terminal command 'chmod a+x ~/Desktop/gen_debug' and run the script from your Desktop.
My system is as follows:
Dell Latitude E6410 (I7-620m, Nvidia 3100M, 8GB DDR3, 512GB SSD, 1440x900 display, BIOS: A17) Wi-Fi: Broadcom BCM 94352HMB (replaced original Wi-Fi card) BIOS (version A17) configured as follows (leave default unless listed here): Boot Sequence: USB, Internal HDD, CD/DVD, Modular Bay HDD; Boot List Option: Legacy; Integrated NIC:Enabled; Parallel Port: Disabled; Serial Port: Disabled; SATA Operation: AHCI; Misc Devices: Enable Modular Bay, Camera, External USB, Microphone, Media Card and 1394; Latitude ON Reader: Disabled; Keyboard Illumination: Auto ALS and Input; Ambient Light Sensor: Enabled; OROM Keyboard Access: Disable; TPM Security: Disable; Computrace:Deactivate; CPU XD Support: Enable; Performance: Enable all options; Power Management: Disable Wake on AC, Disable Wake on LAN/WAN, Express Charge: Standard, Charge Behavior: Enabled; Keypad: Fn Key Only; Mouse/Touchpad: Touchpad/PS-2 Mouse; USB Emulation: Enable Legacy; Fn Key Emulation: Disabled; Fastboot: Thorough; Virtualization: Enable Intel Virtualization, Disable VT for Direct I/O, Disable Trusted Execution; Wireless Switch: Bluetooth and WLAN; Wireless Device Enable: Bluetooth and WLAN;
Versions of the software used in this installation are listed below the installation steps. EFI and kexts for Catalina are attached to this first post in E6410-Catalina.zip. CLOVER configuration is specified below the installation steps.
Wi-Fi connection to an Access Point is delayed when using AppleALC for sound. Do not use Apple ALC. Use VoodooHDA pkg 2.9.2 v15 for sound.
Steps to install Catalina on a Dell Latitude E6410 (BIOS A17, NVidia 3100m)
If you want to upgrade to 10.15.5, see instructions at this post.
If you want to upgrade to 10.15.4, see instructions at this post.
Follow instructions below for 10.15.2 and 10.15.3.
Make sure that your system matches my system description above (including BIOS version, Wi-Fi card, BIOS settings) If performing an upgrade from Mojave or a previous version of Catalina, backup your Mojave or Catalina partition! (Carbon Copy or similar) Download Catalina Installer Download DosDude Catalina Patcher Use DosDude Patcher to create Catalina USB Installer Delete LegacyUSBInjector.kext (we're using @RehabMan's USBInjectAll.kext with custom SSDT) and delete SIPManager.kext (CLOVER is managing SIP) from Catalina USB Installer's /Library/Extensions folder Copy all but the FakeSMC sensor kexts in E6410-Catalina.zip (attached) LE folder to the Catalina USB Installer /Library/Extensions (copy all kexts (including FakeSMC.kext) but not the FakeSMC sensor kexts) Install CLOVER Bootloader (Legacy) on USB Installer using the EFI in the E6410-Catalina.zip (attached). Use the CLOVER configuration specified below. Be sure to replace the XX-MASKED-XX parameters in the attached config.plist with your own values. Reset your Latitude E6410 NVRAM by doing the following (this may be important if you're making changes to your existing EFI and won't hurt anything if you're not making any changes) turn-off your laptop remove A/C power and main battery press and hold the power button for 30 seconds restore A/C power and battery Boot your Latitude E6410 from the Catalina USB Installer that you created in steps 5-8. Select "Reinstall macOS" (note that I have existing installations of Mojave and High Sierra on my Latitude E6410, so it's possible that this menu item changes to "Install macOS" if you don't have any previous macOS installations). Select your Catalina destination partition (which will be your Mojave or previous Catalina partition if you are upgrading) After the Catalina Installer reboots the first time, boot from the "macOS Installer" partition on the disk that you selected as your Catalina destination (not the macOS installer on the USB) After the Catalina Installer reboots the second time, boot the Catalina macOS Installer on the USB Select the Post Install Patcher utility Select only the following Post Install Patches (no other patches / options) Install Patch Updater Legacy Video After the Post Install Patcher reboots, boot from the newly installed (or upgraded) Catalina partition and complete the macOS configuration Remove these kexts (if they exist) from /Library/Extensions: LegacyUSBInjector.kext, LegacyUSBVideoSupport.kext and SIPManager.kext If you are performing a fresh installation of Catalina: Install CLOVER (LEGACY - NOT UEFI) on your boot disk and configure EFI using files in the attached E6410-Catalina.zip. Use the CLOVER configuration below. Be sure to replace the XX-MASKED-XX parameters in the attached config.plist with your own values. Install all kexts in the attached E6410-Catalina.zip LE folder to your /Library/Extensions folder. Copy HWMonitor from the application folder in the attached E6410-Catalina.zip to your Applications folder. Install VoodooHDA (I installed using the Classic method) Skip to Step 21 If you are upgrading from a previous version of Catalina using the instructions from this thread or from Mojave that you installed using the instructions here: Replace 3rd-party kexts in EFI/Clover/kexts/Other with those in the attached EFI folder. Replace EFI/Clover config.plist with the attached config.plist (Be sure to replace the XX-MASKED-XX parameters in the attached config.plist with your own values) Replace EFI/Clover/ACPI/patched with the files in the attached EFI/Clover/ACPI/patched Replace 3rd-party kexts in /Library/Extensions with those in the attached LE folder Remove VoodooSDHC.kext from /Library/Extensions Re-install VoodooHDA if necessary (I installed using the Classic method for Catalina) Ensure PROPER kext installation: If you're manually installing kexts in /Library/Extensions, make sure that you execute the following (in terminal) cd /Library/Extensions sudo chown -R root:wheel *.kext sudo chmod -R 755 *.kext sudo kextcache -i / After you execute 'sudo kextcache -i /' you should observe that ALL kexts are allowed. If not, your kext directory attributes are probably incorrect. Repeat kext installation and try again. Reboot from your new/upgraded Catalina partition Welcome to macOS Catalina! Change the keyboard type to ISO (System Preferences > Keyboard > Change Keyboard Type) Swap the Command and Option keys (System Preferences > Keyboard > Modifier Keys) Set hibernatemode: In terminal, execute sudo pmset -a hibernatemode 0 sudo rm -f /var/vm/sleepimage sudo touch /var/vm/sleepimage sudo chflags schg /var/vm/sleepimage

What is not working (that was working in Mojave)
SD Card Slot (had to remove VoodooSDHC.kext which caused system freeze on wake)
Known Issues and Their Solutions
(Solved - no further work required) Clover r5118 requires the config.plist key <key>NoDefaultProperties</key><false> to permit macOS to boot with Clover's "Inject Nvidia" = True. See details here. config.plist in the attached E6410-Catalina.zip archive includes this change. (Solved - no further work required) EFICheck is loaded. Solution is to install EFICheckDisabler.kext which you can get here. EFICheck.kext is included in the attached E6410-Catalina.zip archive. (Solved - no further work required) Some users experience display issues. The solution is to remove Device (PNLF) from the DSDT. Use the attached DSDT. Removal of PNLF will disable sleep on lid closure. Device (PNLF) can be added without modifying the DSDT by enabling the Clover PNLF ACPI patch. The attached Clover config.plist enables the PNLF DSDT patch. Disable the Clover PNLF patch if you experience display issues. (Solved - no further work required) USB sleep/wake power IORegistry keys are not injected (not included in Mojave's or Catalina's IOUSBHostFamily.kext). Solution is to added SSDT-USBX.aml to EFI/CLOVER/ACPI/patched. The attached SSDT-USBX.aml includes USB sleep/wake properties for MacBookPro6,2 from High Sierra 10.13.6 IOUSBHostFamily.kext. (No solution yet) Brightness slider does not work in System Preferences > Displays. Brightness is easily controlled with Dell brightness keys. There is some work on this later in this thread, but I will not be solving this as I'm content with the Dell brightness keys (and Ambient Light Sensor works to auto-adjust brightness). (No intention to solve) Display Settings in System Preferences are "garbled" when bright slider is visible. This is a known issue with the legacy graphics patch and does not affect laptop operation. I continue to refine the DSDT and CLOVER config.plist to optimize my Latitude E6410 for multi-booting between various macOS versions (High Sierra, Mojave and Catalina at the time of this writing). If you upgrade your Latitude E6410 EFI using my attached EFI, you may find that your Latitude E6410 is stuck in a boot-loop that ends in a white screen and reboots. Clear your system by doing the following: turn off your laptop, remove A/C power, remove the main battery, press and hold the power button for 30 seconds, restore A/C power and battery, boot normally. I have only found this to be necessary (very rarely) after making an EFI change, but you may find it helpful if making kext changes in /Library/Extensions as well. (Solved - no further work required) Brcm firmware does not update when using BrcmFirmwareRepo.kext in /Library/Extensions. Solution is to install BrcmFirmwareData.kext and BrcmPatchRAM3.kext in E/C/k/O with Clover "Inject Kexts" = YES. (Solved - no further work required) Laptop does not sleep when closing lid. Solution appears to be a combination of adding Notify (LID0) code to Method (BTNV) and adding Device (PNLF) in the DSDT. I am using the same EFI for High Sierra 10.13.6, Mojave 10.14.6 and Catalina 10.15.3 and it works in all three macOSes. (No solution yet) No SD Card Slot (had to remove VoodooSDHC.kext) - I read somewhere that there is a solution that does not require any kexts (just a DSDT edit). Haven't yet implemented this fix. (Not a problem that needs to be solved - leaving for historical purposes. I am running Catalina without this.) - IOHWControl does not load under GFX0 (as observed in IORegistryExplorer). Solution (if it needs to be solved) is to install AppleHWSensor.kext from a DosDude-patched Mojave /S/L/E in Catalina's /L/E. Copy and install your own or use the kext attached to this post. (Solved - no further work required) Wi-Fi connection is delayed until a minute or so after boot - Use VoodooHDA and NOT AppleALC (Solved - no further work required) External USB ports do not work after waking from sleep (S3) - Upgrade Lilu.kext and replace BrcmFirmwareRepo.kext and BrcmPatchRAM2.kext (in /L/E) with latest BrcmBluetoothInjector.kext, BrcmFirmwareRepo.kext and BrcmPatchRAM3.kext. (Solved - no further work required) Boot and shut-down time of Catalina is slower than Mojave - Upgrade Lilu.kext and replace BrcmFirmwareRepo.kext and BrcmPatchRAM2.kext (in /L/E) with latest BrcmBluetoothInjector.kext, BrcmFirmwareRepo.kext and BrcmPatchRAM3.kext. (Solved - no further work required) Wi-Fi is not immediately available at OS startup - Upgrade Lilu.kext and replace BrcmFirmwareRepo.kext and BrcmPatchRAM2.kext (in /L/E) with latest BrcmBluetoothInjector.kext, BrcmFirmwareRepo.kext and BrcmPatchRAM3.kext. (Solved - no further work required) Laptop freezes on wake - Remove VoodooSDHC.kext from /Library/Extensions
Tips for Improved Performance (on this and other older systems)
System Preferences > Spotlight > Search Results: Uncheck all options System Preferences > Spotlight > Privacy: Add all Volumes System Preferences > Accessibility > Display: Check "Reduce motion" System Preferences > Accessibility > Display: Check "Reduce transparency"
If your fan is always running and temps are good, try pressing Fn + z (I haven't noticed this issue for a while since I completed DSDT edits for Mojave, but keeping this here for historical purposes)
CLOVER Installation: Use these configuration options (Install Clover LEGACY - NOT UEFI)
Install Clover in the ESP Boot Sectors Install boot0af in MBR Clover for BIOS (LEGACY - NOT UEFI) booting Clover EFI 64-bits SATA BIOS Drivers, 64-bit Recommended drivers FSInject File System drivers ApfsDriverLoader Install RC scripts on target volume Themes Choose your desired theme Install Clover Preference Pane After clicking "Continue", if prompted with "This Clover package is incompatible with this version of macOS," install anyway
After CLOVER installation is complete Copy the following from the attached E6410-Catalina.zip ACPI patched contents config.plist (change XX-MASKED-XX values to your own) kexts/Other (remove all other kext folders) Remove christmas and new year folders from themes (if present)
Thanks to those who contributed to my Mojave solution and to the DosDude team (for the incredible macOS patchers), I think this Catalina installation was the easiest macOS installation that I have experienced (so far). Many thanks to @Slice and his team for the incredible work on CLOVER and for continuing to support old legacy systems like this. Also, thanks to @Mieze and @headkaze and others I'm sure for maintaining the Brcm kexts. And finally, I still prefer to manually apply patches to the DSDTs in my systems. CLOVER offers extensive patching functionality, but I'm old-school and like to have an error-free, fully-patched DSDT with a simple CLOVER config.plist. I think that this manual DSDT patching approach (which required an extensive review and debugging of the original unpatched DSDT in this thread) is the reason that this Latitude E6410 is such a perfect MacBookPro6,2. Thank you @RehabMan for being a great teacher and for always insisting on problem reporting files .
