The false -> unknown is to be expected. Without it, context
does not understand that "Label" is similar to "textext".
As an alternative, it is also possible to do

\forceMPTEXcheck{Label}

This typically means the the embedded TeX run for the textext
failed, but the problem could also be that the entire metapost
run was wrong.

Because even simple backgrounds fail (and only on MacOSX), end-of-line
stuff seems a likely candidate. What is the contents of the
test-mpgraph.mp?
