TL;DR
Logitech's Logi Options+ and G Hub stopped launching on macOS after a security certificate expired, returning peripherals to default settings. Logitech has released manual patches with an updated certificate, but the apps' built-in updater is broken so users must install fixes themselves.
What happened
On Monday some macOS users found Logitech's Logi Options+ and G Hub apps would not start and observed that accessory customizations had reverted to factory defaults. Logitech says the problem was caused by a security certificate used to secure inter-process communications that had been allowed to expire; the expired certificate prevented the software from starting. The company's Head of Global Marketing acknowledged the error and apologized. Logitech is providing patch installers for both apps that include an updated certificate, and it cautions users to apply the patch rather than uninstalling and reinstalling the apps — doing so can remove stored settings. Because the expired certificate also disabled the apps' automatic updater, Logitech cannot push the fix remotely; each affected app must be patched manually. The supplied patch supports macOS 13 Ventura, macOS 14 Sonoma, macOS 15 Sequoia, and macOS 26 Tahoe, with fixes for older releases to follow.
Why it matters
- Peripheral custom settings can disappear or revert to defaults, disrupting users’ workflows.
- A single expired certificate disabled multiple apps and their update mechanism, showing the risk of certificate management failures.
- Users must manually install patches because the apps' built-in updater was affected, increasing support burden.
- Not all macOS users are covered yet: Logitech's fix currently targets the last four macOS releases, with older-version support pending.
