Sharing configurations between Mac & PC?

Yes, the same BikeCAD configuration files can be used on either a Mac, a PC or on Linux. If you start out with the same configuration files on a few different machines, your preferences will be the same on each machine. Of course, as you modify preferences on one machine, the others will not automatically update. If you'd like to ensure that preferences are updated across several machines, you can change the location of your configuration files to a shared drive accessible to each machine as described at: bikecad.ca/changing_configuration_file_location. Alternatively, you could locate the configuration files in a directory that is managed through a service such as Dropbox.
