PiLyzer 3.1.1 for macOS 13+, Universal (Apple Silicon and Intel).
CH1, CH2 and CH3 now appear before connecting an instrument, so the three-channel capability is visible immediately. Saved two-channel settings are preserved and extended with CH3. Once connected, the panel follows the instrument's actual capabilities, including older two-channel firmware.
The offline rate preview uses the Pico 2 firmware's 97-cycle ADC timing. Acquisition remains disabled until a device or Demo is connected.
Validation: 76 core tests passed; both Universal architectures built and the bundle signature verified. The running macOS app was checked while disconnected: all three channel controls and measurement columns are present.
Unzip the app and move it to Applications. The bundle is ad-hoc signed, not Apple-notarized; macOS may require System Settings → Privacy & Security → Open Anyway on first launch.
