With the "prod" version:
create a new project on the desktop ("contentproject")
choose IOS as platform
output dir is 'bin'
add a new item -> spritefont description
name: alias12, content of the file ... alias 12 as the orginal, nothing changed
BUILD => BOUUUMMM the app crash !!!
With the "development build"
BUILD => ERROR
"processor 'font description processor' has unexpected failure"
result on the desktop
a contentproject file
NO 'bin'directory, no xnd file
conclusion: on Mac it's now impossible to create XNB file !
