Ninno0 Posted January 21, 2018 Author Share Posted January 21, 2018 I realized that the guide referred to the A20 bios and I had A22. I made a downgrade of bios and the installation started. Now I proceed and update you on the outcome. Thank you Link to comment Share on other sites More sharing options...
Ninno0 Posted January 21, 2018 Author Share Posted January 21, 2018 Almost everything works. For the audio I had to install the kext for ALC3226 But I do not work Wifi, you confirm that my Intel AC7260 is not compatible? In which case can I buy to solve the problem?
