Family Tree Maker is available for both Windows and Mac, but users should pay attention to the version and compatibility requirements when moving between computers. FTM Technical Assistance can be useful when a tree needs to be transferred between different operating systems or when installation and file compatibility questions arise. Always create a backup before moving your genealogy database to another computer. After opening the tree, check your people, relationships, sources, photographs, documents, and notes. FTM Technical Assistance can also help troubleshoot issues involving media paths, software installation, or unexpected behavior after transferring a tree. Keeping current backups makes it easier to return to a working version if something goes wrong during the process.
