[Sugar-devel] Getting Sugar to run on certain mac chipsets

[Caroline Meeks]

Hi,

The current status is that SoaS + CD Boot Helper work on many macs.

On some macbooks we need to need "nomodeset"

Today at the Lilla Fredrick School it booted through all the dots appearing
then went to the shell and could not find boot.  The exact same USB and boot
helper boots my iMac just fine.

Any thoughts on either of these issues?

Thanks,
Caroline
