The Logitech Blackout: How an Expired Certificate Bricked Your Mac Mouse Settings

The Logitech Blackout article, published on 7 January 2026, explains that macOS users of Logi Options+ may have had settings fail to apply because Logitech did not renew a digital certificate, preventing the software from connecting to its servers. The expired Apple developer certificate means the backend services cannot start correctly, causing the application to freeze on launch as a result.

Because macOS verification marks the affected components as untrusted, the backend services are blocked by Gatekeeper, which can also lead to higher heat and reduced battery life on MacBooks. A temporary workaround advised in the piece involves manually adjusting the system clock to 5 January 2026 or earlier, then launching the software to apply and save settings before restoring the current date. The article notes this fix only works for the current session and must be repeated after a reboot.

An alternative measure suggested is to install Logi Options+ version 1.44, which is less affected by the certificate expiration, and to disable automatic updates to prevent reverting to the affected release.
