I'm trying to collab with my friend but he has a MAC. We both have the same refills in the exact same folders in the Reason folder the same way. If I do a song and want to send him the Reason file and he tries to open it, it ask him to locate the files because they are missing. If I send the file to a friend with a PC, it loads up the correct way with no problems. I was wondering if anybody could shed some light on my problem. I'd appreciate it thanks.
