Mapping on the PC and Mac
First a disclaimer, I work at Mindjet. I'm mostly on the PC, but I've started to dabble and get up-to-speed on Mac as well. In general, map files will function on both Mac and Windows. The PC version has over 10 years more development than the Mac version which was only introduced a few years back. So, there are a things that you can do on the PC that you cannot do with the Mac version. Since many MindManager users have recently jumped from PC to Mac, they want all the functionality that used to be in their windows version. That, unfortunately, can be heard in the forum. I'm working with our product team and providing as much feedback as I can to help drive our future Mac updates forward and create greater fidelity between the applications. That said, for most people, there should be no issue with sharing maps on both platforms. For some of the advanced users, we're listening to their needs and incorporating the feedback to make the necessary improvements in our future releases.
Hope this helps,
A bump for this almost 4 year old question.
What are the new developments in Cross Platform Mind Mapping. Inspiration 9 seems to be working quite well for me on both platforms.
