I have two computers - a MAC at work and a PC at home. I need to be able to work on the same project in both places. How do I achieve this?
See here for information about how to move projects between computers: http://manual.audacityteam.org/man/audacity_projects.html#move
Also, you will need to be careful about file names. Windows is more restrictive than Mac about valid file names. (see: https://msdn.microsoft.com/en-gb/library/windows/desktop/aa365247(v=vs.85).aspx)
