macOS  on Intel NUC7i3BNH

This repo is currently compatible with macOS Catalina and OpenCore 0.7.3

This repo contains information for getting macOS working on an Intel NUC7i3BNH.

This EFI is built and tested on Catalina 10.15.7: for the moment I stick with Catalina (Supplemental + Security Update - Build 19H1323) since I need a machine as stable and reliable as possible as a daily driver. However Big Sur compatibility should be fine (but untested).

Overview

What is an Intel NUC? It is a tiny barebone PC size of a few CD cases piled on top of each other.

Mine is NUC7i3BNH which is the Core i3 model with a 2.5'' slot for an additional SATA drive coupled with a BenQ PD2500Q which is a 2k 25" calibrated monitor.

BIOS Settings

Update to the latest BIOS version, then load BIOS Defaults and finally in the Advanced submenu change the following settings:

Devices -> USB -> Port Device Charging Mode: Off
Devices -> USB -> USB Legacy -> Disabled
Power -> Wake on LAN from S4/S5: Stay Off
Boot -> Boot Configuration -> Network Boot: Disable
Boot -> Secure Boot -> Disable

Generate your own SMBIOS Information

For privacy reasons, all SMBIOS information has been wiped out in the configuration file EFI/OC/config.plist.

You need to generate your unique SMBIOS info by yourself (recommend to use CorpNewt's GenSMBIOS), and inject them into your config.plist.

For dual-booting systems, Windows Activation may fail due to different hardware UUID generated by OpenCore

According to OpenCore Official Configuration, you are highly recommended to inject the original Windows system UUID to PlatformInfo -> Generic - >SystemUUID in EFI/OC/config.plist: run wmic csproduct get UUID command in Windows PowerShell app

USB Port Mapping on NUC chassis

The active and working USB ports are listed in the following table, while all unused or non-referenced USB ports are accordingly removed:

USB 2.0 Port Name	USB 3.0 Port Name	Hardware Location	Controller
HS01	SS01	Front RIGHT socket	Primary XHCI
HS02	SS02	Front LEFT socket	Primary XHCI
HS03	SS03	Rear BOTTOM socket	Primary XHCI
HS04	SS04	Rear TOP socket	Primary XHCI
HS08	n/a	Internal Bluetooth port	Primary XHCI
n/a	SS01	Rear USB-C socket	Secondary XHCI

Primary XHCI: 8086:9f2f
Secondary XHCI: 8086:15db(recognized as a subsystem for Thunderbolt Controller JHL6340)

Secondary XHCI interface enables the unique USB type-C Port (which offers USB 3.1 gen2) with DisplayPort 1.2 functionality present on NUC7i3BNH. Why is this aspect so important for my config?

Background:
- a known issue (Reddit & Mac mini 2020 M1, Reddit & Mac mini 2018, MacRumors & Mac mini 2020) between my monitor BenQ PD2500Q and Mac is a vertical line on the right side of the display at all resolutions except 1920x1080 HD one;
- this issue is related to HDMI port used for connecting display to NUC7i3BNH;
- a such issue is also documented for Mac mini 2018 or 2020 machines using HDMI ports;
Solution: using a USB type-C (from NUC7i3BNH) to HDMI cable adapter fixes the issue for all BenQ PD2500Q available resolutions even at highest QHD one.

Optional Settings

Increase Launchpad icons number

By default, the Launchpad shows the icons in 5×7 format (i.e. rows x columns).

Since BenQ PD2500Q is a 2k 25'' monitor, type in Terminal the following commands:

defaults write com.apple.dock springboard-rows -int 7
defaults write com.apple.dock springboard-columns -int 10;killall Dock

Relaunch the Launchpad to see the icons are changed now.

Finally you can revert to the default setting with the following commands:

defaults delete com.apple.dock springboard-rows
defaults delete com.apple.dock springboard-columns
defaults write com.apple.dock ResetLaunchPad -bool TRUE;killall Dock

(Warning: the last command also will remove any custom folders you have created)

Make macOS zsh Terminal colorful

The default macOS Terminal looks very lame since it lacks in visibility: things should be colorful like Ubuntu. In the following steps, a proper solution for that is given without installing any custom theme:

Choose any black theme first as the color combination of my snippet is dark theme friendly
Open Terminal and type:

cd
touch zshrc
open zshrc

Append the following code in the file:

export CLICOLOR=1
export LSCOLORS=GxBxCxDxCxegedabagaced

Save the file and quit your default editor
In Terminal type:

mv zshrc .zshrc

Quit Terminal (cmd + q)
Now open a new Terminal window and the changes will be reflected

How did the customization worked?

By setting CLICOLOR=1 you are enabling colors.

LSCOLORS is the variable where you will define which file should display what color: it is used to color the directory and file list. It provides you 11 positions, each with FB (foregroundColor backgroundColor) combination. Thus it contains 22 characters. Below is the details of which position means what:

directory
symbolic link
socket
pipe
executable
block special
character special
executable with setuid bit set
executable with setgid bit set
directory writable to others, with sticky bit
directory writable to others, without sticky

The colors for each position are placed as FB format; below is the list which color means what:

a: black
b: red
c: green
d: brown
e: blue
f: magenta
g: cyan
h: light grey
A: bold black, usually shows up as dark grey
B: bold red
C: bold green
D: bold brown, usually shows up as yellow
E: bold blue
F: bold magenta
G: bold cyan
H: bold light grey; looks like bright white
x: default foreground or background

The colors mentioned above are ANSI colors, but according to the version of your macOS or terminal, they may differ a little.

Dual Booting: fix Windows time

Windows uses local time by default while macOS uses universal time. You can switch Windows to use universal time. Open up a command prompt in Windows as an administrator and copy and paste this in:

reg add "HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\TimeZoneInformation" /v RealTimeIsUniversal /d 1 /t REG_QWORD /f

That will make Windows use universal time instead of local time. Then update your clock via the built-in internet time setting to update the time.
