Logitech mice and keyboards have been experiencing problems for many users around the world. On January 6, at 23:39 (Baku time), the company's Apple Developer Certificate expired.
As a result, the Options+ application, which is responsible for configuring Logitech mice and keyboards, did not start at the same time for macOS users. The problem affected many devices, including the MX Master series in particular.
The application freezes on a purple animated loading screen and does not respond to user commands. In addition, all custom settings have been lost. Some Mac owners have also encountered overheating of laptops and faster battery drain due to the Options+ background process being stuck.
The problem only affected the macOS operating system. In this system, applications do not start automatically when the developer certificate expires — this is one of Apple's security requirements. Apple is not to blame for the incident, since timely renewal of the certificate is the direct responsibility of the developer — Logitech.
The incident was surprising given Logitech's market position: the company controls about 21% of the computer mouse market and has millions of active users among Mac users.
While older models continue to work, newer devices like the MX Master 3S and MX Master 4 have effectively lost some of their functionality, as their extensive capabilities are unavailable without Options+. Logitech's G HUB software for gaming also failed to launch on Mac.
A few hours later, Logitech released a patch that had to be manually downloaded and installed to fix the problem. Once the update was installed, full functionality was restored to the devices.
