Logitech mouse users on macOS (myself included) woke up on Wednesday morning to find they were locked out of their mouse customizations after the company made the “inexcusable mistake” of not renewing a security certificate. This broke both it Logi Options+ and G HUB configuration apps, reports MacRumors.
Logitech devices, including the MX Master series mice (mouses? meeces?) and MX Keys keyboards stopped working properly as a result of the expired security certificate. This meant that any custom settings, such as button mappings and scrolling behaviors, did not work. Logitech users soon took to Reddit to complain.
macOS uses Developer ID certificates to verify the legitimacy of software. When Logitech allowed its certificate to expire, its app lost their authentication and macOS refused to run them. In some cases this led to the apps (and users) being trapped to an endless boot loop.
Logitech did quickly release a patch for macOS 26 Tahoe, macOS 15 Sequoia, macOS 14 Sonoma, and macOS 13 Ventura that resolves the issue. However, users are required to download and install the patch manually, since the expired certificate also prevented the apps’ built-in updaters from working. Users of older macOS versions will get a fix “at a later time,” said Logitech in a support page acknowledging the issue.
“We dropped the ball here. This is an inexcusable mistake,” Logitech spokesperson ATXsantucci admitted on Reddit. “We’re extremely sorry for the inconvenience caused.”
Happily, any custom settings users put in place by users survived the screw-up, and all profile and customizations stay in place after the manual patch is applied. (I can personally testify to this.)
I purchased an MX Master 4 mouse just yesterday for use with both my Mac mini and my Windows PC (don’t judge), so you can imagine my frustration when I found that my new mouse’s features were missing in action. Do better, Logitech!
