My Vehicles

If you have enabled TimeMachine on your system, there is nothing to do for backup the «My Vehicles» database. If not, please make a backup of all files an subdirectories in "$HOME/Library/Application Support/My Vehicles". If you have macOS 10.7 or greater, the database is located in this folder "$HOME/Library/Containers/de.pps4me.MyVehicles/Data/Library/Application Support/My Vehicles". Or use the feature Backup- and Restore.
