Hello, I'm creating an EFI bootable USB image on my rawhide system with this command-line: ./livecd-iso-to-disk.sh --format --efi --overlay-size-mb 400 \ --delete-home --extra-kernel-args selinux=0 ./soas04.iso /dev/sdb1 The resulting USB stick boots fine on a black MacBook, but not on a silver MacBook Pro. The bootable stick does not even show up in the list of boot devices. -- // Bernie Innocenti - http://codewiz.org/ \X/ Sugar Labs - http://sugarlabs.org/ -- fedora-devel-list mailing list fedora-devel-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-devel-list
