Well, I actually am able to get my 2010 model Mac Mini to boot from a USB Thumb Drive now. Lots of tinkering I was able to write the haiku-anyboot.image to the USB Thumb Drive in OS X and then with a bootable CD with reFit on it, it can now see the BeOS Thumb Drive and actually boot from it. Using wired Apple mouse and keyboard of course. No wireless.
Unfortunately, Haiku does not even see the built in ethernet port and I even tried a Apple USB Ethernet dongle and Network Preferences sees it but it does not seem to communicate to the network at all. So, close, but no cigar.
Sound also does not work. The Media Preferences see the HD Audio but no sound. Tried Media Player and it acts like it sees the data but no sound. 8-(
So, can boot from either a Live CD or if you do what I did above, boot from a USB Thumb Drive with Haiku on it. Just not really too functional when there is no sound or internet.
Anyway, wonder if any gurus have an idea on how to get sound or network running in this config?
Was nice to be somewhat successful after spending hours tinkering and getting it to finally boot Haiku though. hehehe
