MX Master 4 Firmware Update - Stuck on 27.0.15, Others Have 27.1.16 - How to Trigger Update on macOS?

Hey folks,

I’m on firmware 27.0.15 for my MX Master 4, but I’ve seen people on the Logitech site reporting 27.1.16 available. Logitech mentioned the rollout is region-dependent a few months back, but I still haven’t received it.

Does anyone know how to manually trigger the firmware update on macOS?

Is it possible to temporarily switch region in Logitech Options+/Logi Device Manager or VPN to force the update?

Has anyone tried something like that or found a reliable method?

I’m specifically looking for the update because I’ve been having battery drain issues and would like to get the latest firmware.

Any tips or experiences appreciated.

Thanks!
