I’m looking for purchase links to the update my WiFi/Bluetooth board on my 2012 15” MacBook Pro retina system so I can use Sidecar to connect my iPad. Currently running macOS Catalina and have a 2020 iPad Air Thank you!
Sidecar is not supported on your system! Sidecar: Turn an iPad Into a Secondary Mac Display The issue is your systems Model ID is blacklisted from taking advantage of the feature, it’s not the AirPort board. macOS Catalina its self is the gatekeeper.
