Perhaps older UEFI specifications allowed Mac-baked filesystems, or perhaps Apple were/are doing their own thing. The current UEFI specification *requires* a FAT 12/16/32 filesystem type on an ESP partition to boot an OS image/bootloader from - see section '13.3 File System Format': https://uefi.org/sites/default/files/resources/UEFI_Spec_2_8_final.pdf I can't recall the ESP partition format last time I installed and dual-booted Linux on a MacBookPro, c.2014, but I'd wager it was VFAT. --nextPart3037634.oiGErgHkdL Content-Type: application/pgp-signature; name="signature.asc" Content-Description: This is a digitally signed message part.
