Hi @ramon, Do everything as said in the video. I have just succeeded with Mojave 10.14 and Novaspirit Clover zip 1.2. Note the version 1.2 is from the Github and not the old one from the link under the video. Regarding the booting, It was about (dont remember) two boots from the pendrive needed and one or two from my target Samsung evo 970 m2 drive. Each time I saw Clover boot menu I pointed manually to the right drive to boot. (You can not use the Alpha’s built-in nvme drive.) Then I upgraded to the Mojave 10.14.1. It works well except the internal Audio.
I used SanDisk 16GB pendrive with prior Mojave 10.14 installation media created and the Colver in the EFI partition as instructed in the video.
Now I wait for new Clover and tutorials continued from @Novaspirit about how to achieve the alc269 audio and Mojave 10.14.1 working alltogether. Actually I never succeded with the buil-in audio despite several attempts.
Hope this helps.
