This is my personal setup list. Yours may vary.
- 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.
- 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.
- Disable caps lock.
