I upgraded my Mac Mini to Tahoe, and tested Screen Mirror.
IT WORKS!!!!!
While I did not expect the core features to break, I was worried about the Bluetooth Keyboard support. Every once in a while MacOS Bluetooth breaks. Bluetooth actually works better than any other OS including Sonoma. It looks like they fixed one of the (many) bugs I have reported.
I need to test more…but today I am going to sit back, and celebrate that Screen Mirror, and Bluetooth keyboard support still works on MacOS Tahoe. Phew!
