Hi, ChicagoKeri, yeah, I've got a few ideas:
this doesn't have much at all to do with Wifi, or Bluetooth, so you can leave those settings alone, as changing them/shutting them off won't magically make KOTOR 2 run.... in older versions of the game, it was a bug that you had to shut off Wifi and Bluetooth to get the game to start/launch, period. what you'd have to do is see if you can get the App to run with Rosetta 2....here's what the heck Rosetta 2 is, what it does and WHY you need it, especially for KOTOR 2, see link (and may the Force be with you !) If you need to install Rosetta on your Mac - Apple Support (CA)...so what you'd have to do is click on the App/game in question, so it's highlighted, then press Apple+I keys together (get info)..... you should get a long window..... and somewhere in that window should be "Open in Rosetta", then save your changes..... the next time you click on the game to play it, and it doesn't work, then it should ask if you want to install Rosetta 2, say yes.....and let it install, then after it's done so, then hopefully when you click on KOTOR 2 it should start up and run..... I've checked the App store, and the most recent version of KOTOR 2 works with Mac OS 10.9.5..... apparently the Steam version of this game runs fine, at least on M1 Macs... as this game was made by Aspyr, you'd have to contact them for better support than I can offer you....
hope this helps
