The USB-C Magic Trackpad (2024+) does not expose the "Silent Clicking" checkbox in System Settings → Trackpad. The toggle is still present when a Lightning Magic Trackpad is paired — confirmed on my own setup (Lightning MT2 shows it, USB-C MT doesn't) on macOS 26.
But the capability is still there. BTT's own haptic feedback dropdown still offers BTT SILENT Normal Click and BTT SILENT ForceClick, which is proof the Taptic Engine accepts the silent amplitude command. And the underlying defaults keys still work:
defaults write com.apple.AppleMultitouchTrackpad ActuationStrength -int 0
defaults write com.apple.driver.AppleBluetoothMultitouch.trackpad ActuationStrength -int 0
Run both, reboot (logout alone might also work, needs testing), and the USB-C trackpad clicks go silent exactly like the old UI toggle did. Verified working on macOS 26 + USB-C Magic Trackpad.
Would you consider a checkbox in BTT's Trackpad settings that writes both ActuationStrength keys (and, if there’s no easier way, prompts the user to log out or reboot)? That's effectively the full implementation. Apple removed the UI, not the driver behavior, so BTT would be restoring what Apple took away.
