Hey all,
Just want to post about my experience with the new F20B BIOS. This Bios version was released for most of the SKylake/Z170 boards recently by Gigabyte. The BIOS adds support for Kaby Lake, but also does a pretty big overhaul of the UEFI and options as well. Generally this seems like a nice improvement but there are things to note...
I have tested the F20B versions for GA-Z170X-UD5 TH and GA-Z170X-Designare. They both have the same issues/improvements, but other boards may behave differently. First of all, the old bug where the BIOS would add extra UEFI boot entries every time it booted, for the same clover entry, flooding the BIOS with excessive boot options is now gone. It now correctly looks at the entry in EFI/BOOT and only sees this entry once. So that is good.
However in both my cases clover would NOT boot macOS at all until I checked/enabled both "Patch APIC" and "KernelPM" options in clover. This was not necessary in previous versions of the BIOS. If you do not enable these clover options, the boot will hang as soon as clover tries to load macOS (following the ++++++++++++++++++++++ in verbose readout). I don't see any downsides to having these options enabled but it does seem odd that it is required now when before it wasn't. This seems to be a CPUID issue or something related.
