BIOS A17
only HD5500
my XPS15 9560 installl sierra too,in Jan,appstore update some system app(not update to HS),and xps15 can't work too,i update the appleALC and Lilu,and it comes back to work.
OK.
Now the question is display brightness.
After Karabiner-Elements and karabiner.json installed, all Keys except F11 & F12 working, but the default brightness is low, so i can endure it.
Now the sound question resovled, and the default brightness is very high, especially in dark, a big problem!
