Problems

• Sleep / Wake
Unfortunately, sleep is broken on this system at the moment. The system itself can go into and out of the sleep state, but the monitor never wakes up. My other OptiPlex hacc does this too. I'll investigate this!





• External Audio and HDMI Output ‏‏‎ ‏‏‎ ‎‎‏‏‎ ‎ 🎉 FIXED!
Unfortunately, external audio - both DisplayPort and HDMI - doesn't work. HDMI output is also broken, with the system failing to boot with only HDMI plugged in. Strangely, once booted, the system does half-work with HDMI, but is locked at low resolution.

Tip

This was fixed by using a combo of DeviceProperties entries from this excellent repo!





• VGA Output ‏‏‎ ‏‏‎ ‎‎‏‏‎ ‎ 🎉 FIXED!
The "option port" of my 7050 happens to be a jurassic-era VGA connector. As probably expected, macOS doesnt work with the VGA port.

Tip

This was fixed using custom connector patches in DeviceProperties!

System

The specs of the main system that the OpenCore configuration targets.

Motherboard	Dell
CPU	Intel® Core™ i5-7500T
Chipset	OptiPlex 7050 MFF
Generation	Kaby Lake
Memory	8 GB DDR4
Storage	256 GB NVMe SSD
GPU	Intel HD Graphics 630

ACPI

SSDTs used:

• SSDT-EC-USBX-DESKTOP
• SSDT-HPET *
• SSDT-PLUG

Important

SSDT-HPET was compiled by me specifically for this machine model. Along with several ACPI patches, this is used to fix onboard audio, including internal speakers. Without it, macOS will show as having no built-in audio devices.

Note

The framebuffer connector patching was done using this section of the WhateverGreen Intel guide as a reference.

Tip

The device-id has been set to 1B590006 as this fixes up some string-related cosmetics around macOS - such as changing the Metal device name from Intel KBL Unknown to Intel HD Graphics 630.

The previous device-id (12590000) matches more closely but has the aforementioned cosmetic issues. Both IDs work absolutely fine.

Kernel

The following shows the kernel configuration.

Kexts

Kexts used:

• Lilu
• WhateverGreen
• AppleALC
• IntelMausi
• RestrictEvents
• RTCMemoryFixup
• SMCProcessor
• SMCSuperIO
• SMCDellSensors
• VirtualSMC
• HibernationFixup
• FeatureUnlock
• IntelBluetoothFirmware
• IntelBTPatcher
• BlueToolFixup
• OptiPlex7050_MFF_USBMap *
• USBMapDummy

Important

The OptiPlex7050_MFF_USBMap.kext is the USB map created manually by me on my own system. It may or may not work for other 7050 Micro machines. If it doesn't work, please disable it.

Tip

In case you need it for your own mapping, USBMapDummy.kext has been left included but disabled, so you can enable it if you need it.

SMBIOS

Macmini8,1

As it's a cute lil boi, it makes sense to have it emulate a Mac mini, even though its closest SMBIOS would be the iMac18,2 - which isn't even supported anymore.

---

UEFI

Drivers in use:

• HFSPlus
• OpenRuntime
• OpenCanopy
• AudioDxe *

Note

AudioDxe is loaded so that OpenCore can make a boot chime on startup!

Post-Install Tweaks

This is just a collection of my post-install tweaks I apply after installing macOS. They're not really related to OpenCore or the overall functionality of the configuration.

Dark Menu Bar and Dock

Okay, so I'm a bit of a macOS boomer. Having used macOS since long before Mojave's dark mode, I'm accustomed to the regular light appearance of the windows - but I always enabled the "Dark menu bar and dock" option as I loved the look. While I still like dark mode (and use it on iOS), the hybrid light/dark mode on macOS is still my favourite!

The following commands restore that functionality:

Window Server

defaults write -g NSRequiresAquaSystemAppearance -bool Yes

Notification Centre

defaults write com.apple.notificationcenterui NSRequiresAquaSystemAppearance -bool No

Control Centre

defaults write com.apple.controlcenterui NSRequiresAquaSystemAppearance -bool No

About This Mac + System Profiler

defaults write com.apple.SystemProfiler.AboutExtension NSRequiresAquaSystemAppearance -bool No
defaults write com.apple.SystemProfiler.AboutExtension NSRequiresAquaSystemAppearance -bool No

Show Hidden Files

Does what it says on the tin. Shows all files, including hidden ones, in the Finder.

defaults write com.apple.Finder AppleShowAllFiles YES
killall Finder

AirDrop over Ethernet

Makes AirDrop scan Ethernet too!

defaults write com.apple.NetworkBrowser BrowseAllInterfaces 1
killall Finder

Frosted Glass Terminal Theme

Some macOS eye candy.

curl -OL https://raw.githubusercontent.com/Coopydood/OpenCore-Z490E-CometLake/main/EXTRAS/HyperTerm.terminal

Import through Terminal's preferences.

Disclaimer

This repo is simply a dump of my current and up-to-date OpenCore stuff that I use on my machine.

Feel free to use it as an example and modify it however you'd like, but please don't expect it to "just work" - because it probably won't.

Contribute!

If you've found a way to make the configuration better, or have solved issues outlined in the Problems section, please share your changes on GitHub for us all to use! Thank you!
