Q: How to install FTM for Max6 on Mac?
A: You have just to change the install destination when the installer ask you. The default is still Max5.
CAVEAT: If you maintain a Max 5 + Max 6 install: First install for Max 6, then for Max 5, becaus the "remove old files" script will remove automatically from your Max 5 install, even if you set to install in Max 6, so it will break any install in Max 5 done before..
