The EFI folder is 106 Mb. Sounds too much for a simple share.
All of the drivers and kexts are the latest from the opencore GitHub. Strictly nothing else.
I share the list of files in the EFI folder and the config.plist minus the serial number and rom number.
This is a release version. When using the recommended alcid (1) I do not see the audio devices. With alcid=21, I see everything including the SPDIF device.
And I have a ubuntu double-boot, ignore the entry in BlessOverride and the ubuntu folder if you do not need it.
