Moving an Arma 3 profile from Windows to Mac

Arma 3 doesn't sync profiles through Steam Cloud, so moving from Windows to macOS meant copying the files over by hand. Here's how:

  1. On Windows, copy your profile folder. It's in one of these:
    • Documents\Arma 3 - Other Profiles\<YourProfileName>\ for named profile
    • Documents\Arma 3\ if you only use the default one
  2. On the Mac, quit the game.
  3. Open Finder, press ⇧⌘G (Go → Go to Folder), then paste:
    ~/Library/Application Support/com.vpltd.Arma3/
    
  4. Back up whatever is already in that folder.
  5. Copy the Windows profile files in.
