[SoaS] Blueberry SoaS Mac feedback

[Sean DALY]

Hi Gary

I had a [drm] error message and the problem turned out to be a bad ISO.

And, the bad ISO had been downloaded on a Mac and reported as
successfully completed.

I would suggest trying again with an md5 verified ISO

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.

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:

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.
