The image-writer-mac script seemed to work nice and clearly to put the iso onto a 2GB USB stick, though I have no way to test the real result yet (no PC; MacBook Pro wont boot it though you can mount and browse the filesystem content; XO-1s OF think the USB stick has an unknown filesystem if you try to use them to boot/read it).

Starting up the Mac with the alt key shows the CD as a bootable system (a few blinks from the USB led); boots to a sugar on a stick splash screen – 1 second delay auto boot (a few more USB blinks); black screen with cursor for ~10sec or so; and then:

Not looking too good as far as native Mac support goes.

Last few tries of the evening. Just made a regular boot CD from the soas-2-blueberry ISO (Disk Utility is the easy way to do this). The Mac is happy to boot off the disk as far as the 'sugar on a stick' splash screen - 10 sec auto boot countdown, but then fails once it tries to go further with the same message:

	[drm] nouveau 0000:02:00.0: PRAMIN flush timeout

After some googling about, turns out to be the ever present case of unsupported video card drivers, so if you're a Mac user who isn't using and NVIDIA GeForce 9400M or NVIDIA GeForce 9600M GT you might still be in luck (perhaps things like a Mac Mini).

If at the splash screen I hit tab, tab to edit the boot parameters, adding "nomodeset" will get me into a nongraphical boot that works all the way up to just before X start's up, at which point the screen just goes black. Trying "nomodeset single" will boot all the way to a single user root prompt, at which typing startx will again give a black screen. I also gave "driver=vesa" a go but that was a "[drm] nouveau 0000:02:00.0: PRAMIN flush timeout" error.

If you're curious, google for "PRAMIN flush timeout" will turn up a bunch of Mac folks trying to run F12 (and F11 I think), some have eventually managed to hack things up by installing basic generic drivers (non-free most likely), but they were installing to HD so had a read/write filesystem to hack about on ;-)

My poor Mac has never seen so many reboots in one day! Oh well, back to my shiny, proprietary, apple flavoured interface of choice ;-b
