# OpenCore Gigabyte Z370n Wifi + RX 6600
An OpenCore EFI for Gigabyte Z370n Wifi mini-ITX motherboard, with Coffee Lake processor. See compatible macOS version in release. This is my fourth OpenCore build so far. Used as my primary workstation.

Though this is a "ready to use" EFI, it is for my own system, so **use at your own risk**. I recommend everyone to read [Dortania's OpenCore install guide](https://dortania.github.io/OpenCore-Install-Guide/). It's comprehensive, but take your time and have patience, there are no shortcuts to a perfect build.

I'm publishing releases here to reference my own configurations and to share my EFI with others, for a little help on the way. With that said, I will probably not publish a release every time I update my OpenCore build. **Do not forget** to [generate SMBIOS info](https://dortania.github.io/OpenCore-Install-Guide/config.plist/coffee-lake.html#platforminfo) if you are planning on using this EFI in your build, since my releases does not include this information, for obvious reasons.

![About this Mac](https://raw.githubusercontent.com/jimpalompa/OpenCore-Gigabyte-Z370n-Wifi/main/opencore_gigabyte_z370n_wifi_about_this_mac.jpg)

## Overview
- This build runs on a dedicated GPU, alongside the integrated GPU, which is only used for computing tasks and does not drive a display. If you are not using a dGPU you need to follow the [GPU patching](https://dortania.github.io/OpenCore-Post-Install/gpu-patching/) guide.
- No beauty treatments were done in this build, that means no OpenCore GUI and no boot-chime. I want to keep everything minimal. You can enable all of this by following the [beauty treatment](https://dortania.github.io/OpenCore-Post-Install/cosmetic/gui.html) guide.
- Wireless card for bluetooth and wifi is not replaced. I'm using the default motherboard Intel card. If you wish to swap the wireless card, remember to read [wireless buyers guide](https://dortania.github.io/Wireless-Buyers-Guide/) first.

## Hardware
Remember to read the [anti-hackintosh buyers guide](https://dortania.github.io/Anti-Hackintosh-Buyers-Guide/) if you're planning on buying components for a new build.

_** You need to set Internal Graphics > Enabled, then Save & Exit Setup before these options are available. Enter BIOS setup again and confirm settings._

## USB ports
For USB mapping I enabled **seven** physical ports, and bluetooth. Remember that you can have a total of 15 ports per USB controller, this board has only one controller. USB 3.1 counts as two ports for backward compatibility. USB-C port on this motherboard is a non-switch variant, it counts as three ports. See image and table below which ports are available and which I chose to map in USBPorts.kext. Use [USBMap](https://github.com/corpnewt/USBMap) or [Hackintool](https://github.com/headkaze/Hackintool) if you wish to create your own USB map.

| Port | Type | Name | Enabled | Comment |

| A | USB 3.1 Type-A | HS07 + SS07 | ![Yes](https://dummyimage.com/11/0000fd/0000fd) + ![Yes](https://dummyimage.com/11/0000fd/0000fd) | |

_* To max out all 15 ports I only enabled USB 2.0 on port D. I use it for a keyboard/mouse wireless dongle, which only uses USB 2.0._ 
_** I have no PCI bracket for the USB 2.0 Header, so I could not recognize the names for those ports._

## Audio layout
For audio layout i used **layout-ID 5**, it seemed most appropriate. Layout-ID 3 works as well, with the same exact functionality*. All other compatible layouts for this audio chipset were tested and did not work fully.

![Blue audio jack](https://dummyimage.com/11/0000fd/0000fd) Blue audio jack acts as `Line In` 
![Green audio jack](https://dummyimage.com/11/00ad00/00ad00) Green audio jack acts as `Internal Speakers` 
![Red audio jack](https://dummyimage.com/11/e70000/e70000) Red audio jack acts as `Internal Microphone`

![Front panel left audio jack](https://dummyimage.com/11/808080/808080) Front panel left audio jack acts as `Headphones` _(switches from Internal Speakers if plugged in)_ 
![Front panel right audio jack](https://dummyimage.com/11/808080/808080) Front panel right audio jack acts as `Line In` _(switches from Internal Microphone if plugged in)_

![Audio layout](https://raw.githubusercontent.com/jimpalompa/OpenCore-Gigabyte-Z370n-Wifi/main/opencore_gigabyte_z370n_wifi_audio_ports.jpg)
_* The only difference between these layouts is that layout5.xml has the key MaximumBootBeepValue, value 64. It also has different PathMapID for SPDIFOut. To use S/PDIF with this motherboard however, you need to connect an expansion card, which I don't have, so I can't test it._

## What works?
Almost everything works. ~~Wifi~~ and bluetooth (using the internal Intel card), dGPU + iGPU acceleration, HDMI audio, wake up from display sleep. Bottom Ethernet port, all USB ports (only some are enabled) including USB-C, all Audio ports. Sleep, ~~AirDrop/Handoff/Continuity~~, iMessage, FaceTime and other iServices. Only a [few minor things](#known-issues) does not work fully.

## Known issues
- [ ] TRIM during boot takes a long while if it's activated.

_Samsung SSD's are not macOS TRIM-supported. Fixed by setting key SetApfsTrimTimeout to 0. Build now boots instantaneously._

- [ ] Wifi stopped working after Sequoia update.

_macOS no longer natively supports any wireless cards. Perhaps future drivers will solve issue?_

- [ ] AirDrop/Handoff/Continuity does not work after Sonoma update.

_macOS no longer natively supports any wireless cards. Perhaps future drivers will solve issue?_

- [ ] Continuity Camera does not work wirelessly, only works with USB connection.

_macOS no longer natively supports any wireless cards. Perhaps future drivers will solve issue?_

- [ ] I211-AT top ethernet port is not working after Monterey update. It shows up in Network settings, but can't connect to anything.

_I don't mind this, since I'm only using one ethernet port. There are some pre-releases of kexts to get the second port working, but I chose not to use them due to instability._

- [x] System hangs with Windows Memory integrity enabled.

_Running dual OS system, macOS + Windows, enabling Device security > Memory integrity in Windows, system hangs during startup, at the BIOS logo. You will never get past the logo to the OpenCore boot picker. BE AWARE to not enabling this setting in Windows._

### Debugging OpenCore
<details>
 <summary>Quick guide on how to debug OpenCore with my releases.</summary>

My releases are prepared for easy dubugging, all you have to do is download the DEBUG version of [OpenCorePkg](https://github.com/acidanthera/OpenCorePkg). Reminder, it's a good idea booting the debug EFI from a USB stick.

**Swap the following files:**

EFI > BOOT > `BOOTx64.efi` 
 EFI > OC > `OpenCore.efi` 
 EFI > OC > Drivers > `OpenRuntime.efi`

**Change to the following values in** `config.plist`**:**

Misc > Debug > AppleDebug > `True` 
 Misc > Debug > ApplePanic > `True` 
 Misc > Debug > DisableWatchDog > `True` 
 Misc > Debug > Target > `67` 
 NVRAM > Add > 7C436110-AB2A-4BBB-A880-FE41995C9F82 > boot-args > `-v keepsyms=1`

Restart computer and make sure you boot from the same volume you made the changes in. Verbose mode is now active and log files will be saved to the same volume. When you're done and everything works, swap back files from the RELEASE version and revert the values in config.plist.

## Software
A collection of apps that may come handy when configuring your build. Reminder, if you wish to use this EFI in your own build, you need to [generate SMBIOS info](https://dortania.github.io/OpenCore-Install-Guide/config.plist/coffee-lake.html#platforminfo) first. System will not boot without it. Use EFI at your own risk.
