Logitech users on macOS found themselves locked out of their mouse customizations yesterday after the company let a security certificate expire, breaking both its Logi Options+ and G HUB configuration apps. Logitech devices like its MX Master series mice and MX Keys keyboards stopped working properly as a result of the oversight, with users unable to access their custom scrolling setup, button mappings, and gestures.
Logitech actually did drop the ball.
Already installed software keeps running when the cert expires unless the cert is revoked. Apple didn’t revoke the cert. Logitech did something wonky.
