You can save the addons in the user folder. On the Mac this is a bit hidden:
- open the FINDER
- go to "Go" in the menu bar
- press and hold the "option" key to display the "Library" entry
- click on this folder (the "option" key must be pressed)
- change to your user directory:
- /Users/USERNAME/Library/Application Support/Aerofly FS 4 - addons for aircrafts belong here:
- /Users/USERNAME/Library/Application Support/Aerofly FS 4/aircraft - addons for airports (scernery) belong here:
- /Users/USERNAME/Library/Application Support/Aerofly FS 4/scenery/airports - addons for elevation (scernery) belong here:
- /Users/USERNAME/Library/Application Support/Aerofly FS 4/scenery/elevation - addons for images (scernery) belong here:
- /Users/USERNAME/Library/Application Support/Aerofly FS 4/scenery/images - addons for pois (scernery) belong here:
- /Users/USERNAME/Library/Application Support/Aerofly FS 4/scenery/poi
To make things easier for me, I then placed the folder "Aerofly FS 4" in the sidebar.
