Hi Bernie,<div> </div><div>Are you sure you macbook pro is capable of booting linux? I was experimenting at a Apple Store and found that the White Macbooks there were not capable of booting Linux from a CD, let alone Sugar from a Stick. However the Silver Macbook pros booted both fine. White macbooks at the GPA have the same issue. Older white macbooks at the Lilla Fredrick boot fine. So things can be very odd with Macs. <div class="gmail_quote">On Tue, Nov 10, 2009 at 2:40 PM, Bernie Innocenti <<a href="mailto:bernie@codewiz.org">bernie@codewiz.org</a>> wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;"> 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.
