Thank's Hèrvé !
Another question/problem :
thunderbolt port work with graphic adaptater , but not with apple thunberbolt/gigabit ethernet one
i read somewhere , we must turn the bios security to legacy , but i don't know if it's possible with clover , and don't know too how to do that ...
other thing : graphic port ( hdmi ,vga , thunderbolt ) don't support hot plugg ,only plugg before boot.
there is way to solve this ?
Thank 's
