[SOLVED] APFS related BIOS warnings since upgrading to macOS High Sierra (Z170X-UD5 TH)

[amadeusp81]

Is anyone else seeing these warnings (see attachments) since upgrading to High Sierra?

On my machine they started to show up after upgrading to HS and APFS.

Is this harmless? Or do I eventually need to do anything about it? And if yes, could someone point me the way (to a guide maybe)?

Many thanks in advance!

Cheers

Just realised that I probably should have posted this to the "BIOS/UEFI" section. Sorry!

They are not warnings. And they are not coming from BIOS.

They are startup logs from apfs.efi.

Ah, I see, thanks RehabMan! I will dig in now and try to learn more about it.

We're all getting them. Far as I know they are innocuous debug messages and I haven't seen anything about how to squelch them yet. If they caused a slowdown in system boot i might be more concerned about them but for now I just ignore them for the 1/2 second they appear.

OK, thanks aol!
