Logitech users operating on macOS have encountered malfunctions with their input devices and associated software, including observed issues such as altered scroll directions, non-responsive auxiliary buttons, and application boot loops. These problems were reported with devices like the MX Master 3S for Mac.
Cause of the Issue
An investigation determined that the root cause was the expiration of Logitech's Apple Developer Certificate. This certificate's invalidation prevented companion applications, including Logi+, Options+, and G HUB, from launching correctly and from executing automatic updates.
Company Response
Logitech acknowledged the technical oversight, characterizing it as an "inexcusable mistake" and issued an apology for the inconvenience experienced by its user base. The company subsequently established a support page providing guidance on the resolution process.
Resolution Steps
Users are required to perform a manual patch installation to address the software issues. Logitech has provided the following specific instructions:
For Options+ Users:
- Step 1: Download the updated 'patch' installer for Options+ from the official support page.
- Step 2: Execute the downloaded file by double-clicking it.
- Step 3: The installer will complete its process, and Options+ is expected to launch automatically.
- Step 4: Device settings and user customizations should be fully restored.
For G HUB Users:
- Step 1: Download the updated installer for G HUB from the official support page.
- Step 2: Double-click the downloaded 'patch' installer.
- Step 3: When a "software already exists" notification appears, users should exit the installer.
These manual installation procedures are necessary due to the expired certificate's impact on automated software update mechanisms.
