WazzapMigrator Extractor on Mac OSX

On MacOSX Mojave and later you are required to grant WazzapMigrator Extractor access to the folder where your iTunes backup is stored. Without such grant, it will not be able to extract your data.

If prompted, kindly add WazzapMigrator Extractor in OSX preferences as shown in the tutorial below:

OSX preferences -> Privacy & Security -> Privacy -> Full Disk Access

OSX preferences -> Privacy & Security -> Privacy -> App Management 

If you have issues with permissions, try closing WazzapMigrator Extractor, removing the permission alltogether and adding it back.
