This is my personal setup list. Yours may vary.

1. Check networking.
   • May not match network you actually joined, since Apple syncs WiFi networks over iCloud account.
   • If you want to Ethernet via a Thunderbolt Display, attach the cable and restart to make the interface appear. The ones you can add are all false friends.
2. Change Mission Control screen keyboard shortcuts for changing screens.
   • They interfere with subword navigation in Xcode.
   • These need to be changed in Keyboard Shortcuts, not Mission Control.
     • Mission Control offers fewer options.
3. Disable caps lock.
