# Precision 7820 Hackintosh
macOS 10.15 Catalina on Dell Precision 7820 with [OpenCore](https://github.com/acidanthera/OpenCorePkg). Currently working with 10.15.3! If you find something broken, please make a PR!
The docs & tools that helped me set this up are here, a big thanks to:
- [OpenCore Vanilla Desktop Guide](https://khronokernel-2.gitbook.io/opencore-vanilla-desktop-guide/)
- [RehabMan's SSDT USB port mapping](https://www.tonymacx86.com/threads/guide-creating-a-custom-ssdt-for-usbinjectall-kext.211311/)
- [USBMap](https://github.com/corpnewt/USBMap) and [SSDTTime](https://github.com/corpnewt/SSDTTime)
- [OpenCore Configurator](https://mackie100projects.altervista.org/opencore-configurator/)
## Getting Started
Point this at _EFI directory_ of a USB stick or the ESP from your new install. It will download OpenCore + all needed drivers and kernel extensions from the original authors.
```
./make_efi.sh path_to_efi_dir
```
## Hardware & Compatibility
I would love to hear feedback about this configuration from someone with a dual CPU machine!
### It works on my machine™
- 1x Xeon Silver 4114
- 32 GB DDR4 2400
- AMD 7870
- If someone else has this old thing, add `radgpu=15` to your kernel args
### Working
- USB 3 A/C
- USB 2
- Audio
- Ethernet
- Sleep
### Not working / unknown
- Thunderbolt
- SD Card Reader
- Supposedly this should be easy
## OpenCore Settings
It took a while to get everything into place, so an outline of `config.plist` may be useful for others.
### ACPI
#### Patches
- SSDTTime generated
- TMR IRQ 0
- RTC IRQ 8
- HPET _CRS to XCRS
- From RehabMan tutorials
- EHC1 to EH01
- EHC2 to EH02
- Rename XHCI to XHC
- Rename XHC1 to XHC
#### SSDT
USB ports will not work without the RehabMan SSDTs below
- SSDTTime generated
- HPET
- PLUG
- EC
- RehabMan
- XOSI
- UIAC for UsbInjectAll
### Booter
I haven't touched this since I was randomly toggling things on and off to avoid KPs, so maybe a bunch of this stuff can be disabled
#### Quirks
- `slide` related
- EnableSafeModeSlide
- DevirtualiseMmio
- ProvideCustomSlide
- AvoidRuntimeDefrag
- ShrinkMemoryMap
- SetupVirtualMap
- EnableWriteUnprotector
### Kernel
The `*Xcpm` quirks are super important and the system will not boot without them
#### Add
- Lilu
- VirtualSMC
- Does not need companion `VirtualSMC.efi` with OC
- SMCProcessor
- SMCSuperIO
- WhateverGreen
- IntelMausiEthernet
- VoodooHDA
- If you want to use AppleALC, this machine is Layout ID 3. I couldn't get it to work. I am not experiencing any audio quality issues using Voodoo.
- USBInjectAll (with SSDT above)
#### Quirks
- AppleCpuPmCfgLock
- AppleXcpmCfgLock
- AppleXcpmExtraMsrs
- Will refuse to boot without this
- DisableIoMapper
- ExternalDIskIcons
- PanicNoKextDump
- PowerTimeoutKernelPanic
### NVRam
Nothing crazy happening here. It will not boot without the npci flag.
`boot-args`: `npci=0x2000`
### PlatformInfo
I am using the `MacPro7,1` SMBIOS. I am not sure what effect if any the SMBIOS has on the behavior of the system. Please PR a more appropriate SMBIOS if available!
