Check out the Github Discussions for community discussion and support if you need help getting things set up. If you are running into issues or kernel panics or other bugs, please open a Github issue after doing a search to make sure the issue is not already reported. When opening an issue, please provide all the information in the template. If you are getting a panic or crash, please attach the crash log either as a text file or as a picture of the screen (if it crashes during boot). You need to enable verbose logging to see the crash log at boot.
This is a hardware issue and cannot be worked around without Intel support or extensive kernel patching. If you require a USB device to not be disconnected (an external HDD for example), you can use the blue USB 3.0 Type A port on the front of the NUC. This port is connected to the CPU directly (does not go through the buggy PCH) and does not exhibit the same wakeup issue. However, it does experience a separate issue where if you have the device connected before powering on, then it will get disconnected after the first sleep. You should either plug in the device after OSX boots or suffer a single disconnect before the issue goes away.
Windows sometimes modifies the NVRAM variables for force the BIOS to only show Windows as a boot option. If you have an external media with OpenCore installed, you can use it to reset the NVRAM. If you do not have access to an external media with OC installed, you need to open the case and remove the BIOS Security Jumper (see section 220.127.116.11) to reset all BIOS settings.
If the Ridge controller crashes, you won't get DP output (or anything else) from the TB ports. Perform a hard reset by unplugging the power cord and plugging it back in. Then press the power button and wait until your keyboard shows up. Then press Ctrl+Alt+Del to soft-reset and you should see the display working again.
First get into the boot picker menu, and boot into OSX. Then, you need to make sure the right startup device is selected in System Preferences -> Startup Disk. Select your OSX installation you wish to boot into and press Restart. This should fix the issue for future boots.
If this happens during an OSX upgrade, you need to manually select the updater option. After the upgrade is complete, you can configure the Startup Disk.
Before asking for help, make sure you try all the following troubleshooting advice first.
Reboot and when you see the boot logo, you need to hold or repeatedly tap the Alt key (Opt key on Apple keyboards). Sometimes holding works and sometimes tapping works and sometimes neither works. This is a known issue with OpenCore and you have to keep trying.
If you get this message while installing, make sure your BIOS clock is set to the correct time and that you are connected to the internet.
If you get this error while trying to install the HaC mini package, it is because the installer script failed. There are two common causes:
- 2.You do not have Xcode or Xcode Command Line Tools installed. (Run
xcode-select --installin Terminal to resolve.)
If you enable secure boot from the installer, you may not be able to boot into an existing macOS installation or the installer for a new installation. The reason for this is because macOS will be personalized with a random value generated by the installer. This means that you can no longer boot with OpenCore installed to a USB drive as the random value will be different. If you did not install macOS with secure boot enabled, you can either re-install macOS or boot into recoveryOS and run the following command
$ bless --folder "/Volumes/Macintosh HD/System/Library/CoreServices" --bootefi --personalize
Replace "Machintosh HD" with the name of the partition containing the macOS install that will not boot. If you run into an error, make sure you do not have two SSDs installed (temporarily disable one from BIOS), then run First Aid from Disk Utility, and also make sure you are connected to the internet and can ping apple.com (from recoveryOS).
There are known compatibility issues with the DW1820A and the Intel wireless card. There are also known issues with having a second M.2 drive installed (for example Boot Camp Utility does not work if you have two internal drives). One troubleshooting advice is to disable the hardware in BIOS and see if the problem persists. Alternatively, you may wish to physically remove the hardware while debugging the issue.
Follow the existing install directions to update/reinstall the latest version of HaC Mini. This will replace your OpenCore settings but by default a backup will be created in /EFI-backups/OC. If you made changes to the configuration and a reinstall worked, you can try adding the changes back one at a time to see what is the cause of the issue.
You can try booting into safe mode by holding Win+S (Cmd+S on Apple keyboards) during boot. If this does not work, get into boot picker and hold the keys while pressing the number corrosponding to your boot drive. If the issue is resolved check if any extension added in
/System/Library/Extensionsare the cause by enabling them one at a time.
Rerun the HaC Mini installer and select the following options: Verbose Boot, Debug mode, Reset boot-args. If this fails, try it without "Reset boot-args" and then reset NVRAM. If there is a panic, take a picture and include it in your support request.
