Hi! So I got my ISOstick a while ago, and have been very eager to start doing stuff with it. The issue is that it's not really working for me. I have mostly Macs in my house, and the computers that I've tried to boot ISOstick from either don't see it as an optical drive, or don't do anything when I select an ISO.
My primary Mac - a thunderbolt-equipped MacBook Pro from early 2011, sees ISOstick named as whatever I entered in the iso_filename config file. Once I have started isosel, selecting an image restarts the computer, as expected, and starts the image. After that, it appears to freeze up.
Another Mac that I've tested - a black MacBook from 2007 (I think), doesn't see ISOstick as a bootable CD drive at all. I tried installing an alternate bootloader for Intel Macs - a program called rEFIt, that appeared to fix it and show it as a bootable drive. It actually did the same thing my other computer did - showed a bootable cd drive titled as whatever I entered into iso_filename. After selecting an image from isosel, the computer restarts, only this time the ISOstick is now gone as a bootable option, and proceeds to boot to OS X.
I know that Macs, especially newer ones, have limitations on what devices can boot from USB. For example, I know the newer MacBook Airs can only boot from the USB Lion or Mountain Lion installer, nothing else. I'm not sure if you could find a way around this, but if you can't, I understand. I would appreciate some support in getting this to work on older hardware that doesn't have this limitation. Thank you for any help you can offer!
