@mils2003112 A 2014 MacBook Air can run up to macOS 11 (Big Sur). Are you sure you don't have an older model?
As for the EA App, there's no indication it's going to work on older versions of macOS than Catalina (10.15), or that there will be any other way to play EA games in these OSs.
I’m pretty sure, when I click on “about this mac” it says:
macbook air (11-inch, Early 2014)
@mils2003112 Great, then you can install Catalina or Big Sur and start using the EA App. Here are links for each, respectively:
https://apps.apple.com/us/app/macos-catalina/id1466841314?mt=12
https://apps.apple.com/id/app/macos-big-sur/id1526878132?mt=12
Keep in mind that neither one runs 32-bit apps. So if you want to keep using such apps, you'll want to first install an older OS onto an external drive; you can boot into that to run the older apps. If you'd like help with this process, let me know. Keep in mind you do need to go through this process before updating to Catalina or Big Sur.
