Hi Mika,
thx for the link. For the previous attempts I just dd'ed the ISO onto
the USB-stick. Now I used GNU parted to create the GPT and the FAT32
partition so I don't need a Mac to create a grml-stick to boot a Mac:
(parted) mklabel gpt
(parted) mkpartfs primary fat32 32k 1024MB
WARNING: you are attempting to use parted to operate on (mkpartfs) a
file system.
[...]
Ignore/Cancel? i
(parted) toggle 1
boot
(parted) print
Model: SanDisk Cruzer Micro (scsi)
Disk /dev/sdc: 1025MB
Sector size (logical/physical): 512B/512B
Partition Table: gpt
Number Start End Size File system Name Flags
1 31,7kB 1025MB 1025MB fat32 primary boot
(parted) quit
[&& mount $STICK_DEV $USB_MOUNTPT && cp -r $ISO_MOUNTPT/* $USB_MOUNTPT/]
Works fine with grml64-2013-09 and the "No Kernel-Mode-Setting" boot
option (nVidia graphics). Too bad I need a special thumbdrive for Macs
but at least now I know about this ;)
Regards, FLorian

well, too bad I only got my hands on an older MacBook Pro today (to fix
some booting troubles), because I can't boot grml on this thing.
USB-sticks with grml96 don't show up and grml64 on both USB-stick and
CD (the MBP is old enough to still have an optical drive) stop at
"Searching for disk".
A USB-stick with Ubuntu 12.04.3 amd64 on the other hand boots fine
(after not showing the boot menu and some messed up logo at boot).
How did you create the USB stick?
The EFI setup is supposed to work fine:
