> 1) What is the most up-to-date build you folks would recommend?
*Install directly from the Live CD:
(This is a full install; not a live install with persistence)
*VirtualBox appliance Just import into VirtualBox for OSX on your MAC:
*Use "liveinst" command in a sugar root terminal to install to a 4 GB
USB (formatted ext4 no swap)
> Where can I find the instructions for making the Live CD?
* Wiki Instructions: http://wiki.sugarlabs.org/go/Downloads
*Burning a Live CD from an .iso on a MAC This works tg jan 10 2012
Click on the CD.iso ( trisquel-sugar_5.0_i686-20111204.iso) Downloaded
to the desktop
Right click: Open with DiskImageMounter.app
Click on Mounted (trisquel-sugar_5.0_i686-20111204.iso) in Disk Utility
Insert Unused CD in Mac Slot
Click on "Burn" on top bar - (burns and verifies Live CD)
This Live CD boots on a PC and a MAC
*How to boot the trisquel-sugar_5.0_i686-20111204 live CD on your Mac
Insert the CD
Shutdown The Mac
Press Power button and hold the OPTION key down until a windows CD is
displayed to the right of the MAC harddrive
Use ==> arrow key to select the windows CD and hit enter.
Very Slow compared to a VirtualBox appliance
No internet connection on CD - VirtualBox works fine
CD ejects on shutdown of sugar cannot insert it soon enough to boot
with option key
Better to use the CD in a PC
*I recommend a VirtualBox Install for a Mac
*Here is a complete listing of available appliances (Just import the 2
files; after downloading them)

It does not matter the file size is much smaller than a CD. But older
PC's may not handle a DVD

Use the CD/DVD burner on your machine. It will duplicate one at a time.
see section above: Burning a Live CD from an .iso on a MAC
I have no experience in DVD rewriters....

Glad to help by e-mail; cell phone or IRC #sugar.
