Yup, the sessions were likely created/saved WITHOUT checking the box for enforcing PC/Mac compatibility. I agree that the best bet is to find someone with a Mac system to open and re-save for you.(probably ANY Mac system could open the session). I would take along an external drive that can be addressed by a Mac. Once each session is opened on a Mac, then I would immediately consolidate each and every track, and export audio as wav or aiff to a folder, and drag that folder to your drive(in addition to saving the session on your drive). That way, worst case scenario is you could just create brand new sessions and import the audio. Since it was all consolidated back to time zero, all tracks would line up.
