Keeping your system up to date
- Updating the BIOS
- Updating Clover EFI
- Updating Mojave to version 10.14.6 (latest version before Catalina)
Updating the BIOS
Don't forget to keep track of the settings (see post #1).
The latest BIOS from Intel can be downloaded here:
https://downloadcenter.intel.com/product/126148/Intel-NUC-Kit-NUC8i5BEH
Copy the .BIO file on a USB stick and flash the BIOS by hitting F7 when the NUC powers on.
Updating Clover EFI
The files provided by Leesureone and attached in this post just needs to be unzipped and copied in the EFI folder of the USB stick used in post #1.
To do so:
- Mount the EFI partition on your USB Boot Drive by plugging it on your Mac
- Delete the EFI folder on it
- Empty the trash
- Copy the entire EFI folder previously unzipped
Leave the USB Drive inserted into the NUC and restart the computer. Boot from USB Drive by pressing F10 at start and you should be able to see your hard drive at the Clover Boot Screen.
Choose it and boot normally.
Then repeat the process on your hard drive:
- Mount the EFI partition on your hard drive
- Delete the EFI folder
- Copy the entire EFI folder from your USB Boot Drive
- Restart the NUC and voilà!
Note: the files provided by Leesureone are also compatible with Catalina.
Updating Mojave to version 10.14.6 (latest version before Catalina)
The combo update can download here if software update isn't showing it and follow installation as usual (the NUC will restart several times during the process).
Download macOS Mojave 10.14.6 Combo Update
Note that Catalina works as well.
More information provided by Leesureone (from post #430)
With recent bios updates being pushed out by Intel above version 56 as well as updates by Apple to Mojave beyond 14.2 the guide has become outdated and no longer works as is.
Two things additional things are needed at a minimum to be able to reach the Mojave install window.
1. An updated version of the Clover bootloader must be installed, I suggest version 4290 or higher, although slightly older versions will probably work but have not been tested. Rehabman’s version available through the terminal commands in his original guide on Github will cause the installer to halt.
2. An updated config.plist containing an ACPI/DSDT/Patch for an RTC issue that will also cause the installer to stall if your bios is a version higher than 56
***Some users are also apparently unaware that their Samsung 970 EVO plus SSD will also cause install failure if the firmware is not updated first. Visit the Samsung Website for instructions on how to create a bootable USB drive for firmware updates.
The attached EFI folder has all of the above as well as some fixes for onboard Audio and USB C functionality.
If you decide to use it it’s as simple as creating a bootable USB drive using UniBeast and then replacing the EFI folder with the attached.
Once Mojave install is complete and you have then installed an updated version of Clover to your hard drive replace the EFI folder on your hard drive with the same attached folder should finish the job. Afterwards I highly suggest you use Clover Configurator to create a unique serial number (although “continuity” is not an issue unless you have gone the route of adding a Wireless/ Bluetooth card in the one available M2 slot with the appropriate adapter mentioned in various NUC posts). Cheers
Edit: If you have issues with crackling sound from the headphone jack several users have reported success installing all kexts, with the exception of FakeSMC.kext, to the Library/Extensions folder. Audio over HDMI and the headphone jack both should work. (You can probably install all of kexts there, including FakeSMC.kext, if you prefer).
Updated EFI with Clover Version 5100 Catalina ready 12/13/19.
