When I have made OSGeo Live bootable USB drives, I've worked from
the ISO download image. That image includes a combined BIOS MBR
boot/CDROM El Torito boot (isolinux) and an EFI boot (grub). The
Mac sees the EFI boot.<br>
<br>
My 2009 Mac finds it when holding down the Option key on startup.<br>

I'm not sure how two NTFS partitions play into that, but I think
at least the EFI partition needs to be FAT32 (HFS+ is also allowed
as a special case for the EFI partition on a Mac, but it is not
necessary). I suspect a NTFS partition could be added after the
existing partitions on the image if one was careful. The
partition table on the image is a bit weird with the ISO9660
"partition" overlapping the partition table and the EFI partition,
so I'm not sure if normal tools can edit it without messing
something up.<br>

<div dir="auto">As part of my Advanced GIS course, I provided
every student with a 32 GB OSGeo-live flashdrive, formatted
with NTFS on two partitions. They both fine on a variety of
Windows computers (as well as my Pop OS Linux laptop) but
they are not recognized on my students' Macs.

<div dir="auto">I now have the sneaking suspicion that I
will have to format the two partitions to HFS+ and then

<div dir="auto">Is this correct and if yes, how do I do this
without a Mac (I can do the former with gparted but how to
do the latter on Windowsor Linux machine)? Are there
alternative approaches to create OSGeo-live flashdrives
