how do i add addons to aerofly fs 4 on steam ? macOS

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.

Hi, I was wondering how to do this on if I installed Aerofly FS 4 from the Mac app store. The application isn't showing up in application support.

Unfortunately, I only have the FS 4 in the STEAM version on my Mac.

I also had the FS 2 in the AppStore version on my Mac. Unfortunately, I no longer have a record of how I got into my user directory back then. The way somehow went through either "package contents" or "hidden files". It might help to specifically search for "airports" or another directory name.

The folder on Mac AppStore version is: ~/Library/Containers/Aerofly FS 4/Data/Library/Application Support/Aerofly FS 4/
