I have never used a recent Mac but you have done all the stuff required
to set up an EFI partition on the "Live USB" right.

I mean I don't know what to do or how to do it,

and maybe you sent this message before,

but the Mac requires some special features on the EFI partition.

About Grub not seeing harddrives, can't help you with that.

I mean it appears you were the one writing about this before,

but you don't mention whether you have changed Ubuntu version,

or whether anything else changed other than the Mac filesystem.
