[lubuntu-users] Error: "system program problem" . . . the new mouse sweeps clean?

[Ralf Mardorf]

If I google for 'grub chainloading osx on apfs' the second hit is
related to a broken os-prober and seemingly efi is involved. However,
it's about another issue, at least hfs+ is used.

For a bootloader related request - especially since OSX is
involved - consider to join
https://lists.ubuntu.com/mailman/listinfo/ubuntu-users .

On Ubuntu users there might be some OSX users subscribed who don't join
the Lubuntu mailing list.
