- Right-click on Kext Utility in the folder WiFi_kexts and choose open, click open in the following dialog, authenticate with your password
- Wait for Kext Utility to complete – this took maybe two minutes on my setup, and I got an error message in the end, as well as "All done"
- Reboot your computer normally and enjoy WiFi in Catalina
