Has anyone found software to prevent the computer from sleeping when the lid is closed and on battery power that works with the new early 2016 macbook?
Keeping you awake is nearly perfect... If you are looking for a Caffeine substitute.I was also looking for a similar program and found this one:

It is a Caffeine clone but it is compatible with Sierra and has some additional fixes.
