Logitech macOS Certificate Expiration: Why Your Peripherals Failed
Logitech's Logi Options+ and G Hub apps for macOS stopped working due to an expired security certificate. PRISM explores the impact on global users as of Jan 7, 2026.
Premium hardware, paralyzed by a single piece of code. If your high-end mouse or keyboard suddenly felt like a generic $10 replacement this week, it's not a hardware defect—it's a management oversight. Logitech users on macOS are facing a massive software outage that has stripped their devices of all custom functionality.
Logitech macOS Certificate Expiration Causes Chaos
Starting Monday, Jan 5, 2026, Logitech's flagship software suites, Logi Options+ and G Hub, abruptly stopped functioning on macOS. The apps refuse to launch, leaving users unable to access macros, sensitivity settings, or button mapping. All accessories have reverted to their built-in factory defaults, disrupting the efficiency of thousands of creative professionals and gamers.
When Security Certificates Kill Customization
The culprit is surprisingly mundane. According to Joe Santucci, Logitech's Head of Global Marketing, the company inadvertently allowed a security certificate to expire. On macOS, an expired certificate tells the OS that the app is no longer safe to run, effectively bricking the software interface until a new, signed version is released.
