Thanks, but this bootpack is for High Sierra right? Does it also work for Sierra? Do I have to replace the files in /Clover/ACPI/patched with the ones from your link? Just did that, the error persists, my usb isn't working and the battery isn't detected anymore.
BTW I noticed a strange behaviour in my BIOS. It automatically disables Optimus. Sometimes the entry in video is not even there. I use BIOS version A11.
When I enable Optimus, boot into Sierra and reboot, the BIOS entry is gone. When I then reboot again, it's back there but disabled again.
