Keychron K3 vs V3: your questions

No. The Keychron V3 is a wired-only keyboard. It connects via the included USB Type-C to Type-A cable and does not have Bluetooth or any other wireless connectivity.
Both keyboards are compatible with macOS and include keycaps for the Mac layout. The K3 vendor page highlights it as suitable for Mac enthusiasts. The V3 includes a system toggle to save separate layouts for macOS and Windows.
The Keychron V3 is available in both knob and non-knob variants. You must select the 'Fully Assembled Knob' or 'Barebone Knob' version at purchase to get the programmable aluminum rotary encoder.

No. The Keychron V3 comes with double-shot PBT keycaps that are not shine-through. It uses south-facing RGB LEDs which are designed to prevent interference with keycaps rather than shine through them.
