All that grub-install does is copying files into the directory /boot/grub, it makes zero modifications to the filesystem itself or the block device. It doesn't even modify the NVRAM because it's called with "--no-nvram" [1]. The HFS filesystem corruption is most likely a result of the outdated hfsprogs package which has some issues on big-endian systems as I discovered while working on the hfsprogs source code. This will be resolved once I finally update that package. Adrian > [1] > https://salsa.debian.org/installer-team/grub-installer/-/blob/master/grub-installer#L1000 -- .''`.
