How Do I configure a shared folder on my mac That’s accessible for GeoLogTag?
Basically, any Mac folder can be transformed into a shared folder, but in order to be accessible by GeoLogTag, you must have read & write access.
Go to Sharing in System Preferences. This will bring up a screen similar to this one

Enable File Sharing (the lock at the bottom left must be open) and click on the + sign under the Shared Folders column. Browse to the folder of your choice and click Add.
Now the Sharing window should look like this

Your shared folder is now accessible by GeoLogTag. You only need to add the shared folder once.
