LUMIX Tether for Mac: Sonoma, Sequoia & Apple Silicon

LUMIX Tether v2.12 runs natively on macOS 12 Monterey through macOS 15 Sequoia on both Intel and Apple Silicon Macs. The installer is universal, so the same .dmg works on an M1 MacBook Air and an Intel iMac. Most "LUMIX Tether not connecting on Mac" reports trace back to two things: missing system permissions and the USB-C connection mode on the camera.

Install in 4 steps

Download LUMIX Tether v2.12 for Mac, mount the DMG and drag LUMIX Tether.app into Applications.
On first launch macOS will prompt for permissions. Approve USB Device Access and Screen Recording (the latter is only needed if you'll capture the live view in OBS).
Set the camera to PC (Tether) mode from Setup → USB Connection Mode.
Connect over USB-C and launch LUMIX Tether — the camera should appear in the device list within a few seconds.

Sonoma and Sequoia gotchas

Starting in Sonoma, macOS asks again every 30 days whether to allow USB accessories. If LUMIX Tether suddenly stops seeing the camera, check System Settings → Privacy & Security → Accessory Access and re-approve the camera. On Sequoia, the new Background Items screen can quietly disable the LUMIX Tether helper after an OS update — toggle it back on.

Apple Silicon notes

LUMIX Tether is fully native ARM64 from v2.6 onward, so there is no Rosetta penalty on M1/M2/M3/M4 Macs. CPU usage at 1080p live view sits at roughly 8–12% on an M2 Air, leaving plenty of headroom for OBS or Capture One alongside it.

Common Mac issues and fixes

Camera not detected — change the USB-C cable. A surprising number of "charging-only" cables don't carry data.
Live view freezes after 30 seconds — disable the camera's auto power-off in Setup → Power Save.
App quits on launch (Sequoia) — right-click the app, choose Open, then Open again to bypass Gatekeeper after an OS upgrade.
