Logitech Mouse Not Working on macOS? The Expired Certificate Issue with Options+/G HUB

macOS Logicool Troubleshooting Experiment

What Happened

In January 2026, Logi Options+ and G HUB suddenly stopped working on macOS.

The cause was an expired certificate. The certificate required for the apps to run had expired, preventing them from launching.

I ran into this myself yesterday, but honestly I barely noticed at first. The symptoms were subtle — scrolling felt slightly off, button customizations weren’t taking effect. It read as vague wrongness, nothing that screamed “certificate expired.”

How to Fix It

For Options+

  1. Download the latest Options+ patch installer
  2. Double-click the downloaded file
  3. The installer finishes automatically and Options+ launches
  4. All settings and customizations are preserved

No uninstall needed. Just install over the existing version.

For G HUB

  1. Download the latest G HUB installer
  2. Double-click the downloaded installer
  3. If it says “software already exists,” close the installer
  4. Launch G HUB
  5. All settings and customizations are preserved

No uninstall needed here either.

Why Did This Happen?

The Expired Certificate Took Down the Updater Too

This is the most frustrating part.

Because the certificate expired, the app’s built-in auto-updater also stopped working. That means Logitech couldn’t push a fix via the normal automatic update channel. Hence why you have to manually download and install it.

An app with auto-update functionality that can’t auto-update because of an expired certificate. The irony is thick. What exactly was happening with certificate expiry management here?

G HUB’s Baffling Instructions

The G HUB fix steps make no sense on first read.

Double-click the installer → “already exists” appears → close the installer → launch G HUB

Wait — you run the installer, it says the software exists, and then you’re supposed to just… quit it? That’s not installing anything, is it?

My best guess is that running the installer triggers a certificate refresh in the background, without needing to update the actual app binary — so the instructions tell you to quit once that’s done. But still, couldn’t the UI have made that any clearer?

Summary

  • If Logi Options+/G HUB stops working on macOS, suspect an expired certificate
  • Download the latest installer from the official support page and run it — that’s all you need to fix it
  • No uninstall required, settings are preserved
  • Windows users are not affected
