Logitech's Epic Fail: Expired Certificate Bricks Millions of Mac Mice and Keyboards

In a blunder that's equal parts embarrassing and infuriating, Logitech let its Apple Developer Certificate expire on January 6, 2026, rendering its flagship software unusable on Macs worldwide.

Logitech's Epic Fail: Expired Certificate Bricks Millions of Mac Mice and Keyboards The fallout? Logi Options+ and G HUB apps — essential for customizing high-end peripherals like the MX Master series mice and MX keyboards — froze at launch, displaying an endless purple loading spinner and reverting devices to basic default settings.

For users relying on these tools for productivity, gaming, or ergonomic tweaks, it was as if their $100+ gadgets had suddenly turned into overpriced paperweights.

The issue stemmed from macOS's stringent security protocols, which block apps signed with expired Developer ID certificates to prevent potential malware risks.

While Windows users remained blissfully unaffected, Mac owners reported widespread chaos: custom button mappings vanished, gesture controls failed, and scroll speeds reset.

Social media erupted with frustration, from Reddit threads to X posts, with one user lamenting their new MX Master 4 mouse "spontaneously stopped working" mid-workday.

Logitech, which commands roughly 21% of the global computer mice market according to recent industry reports, acknowledged the "inexcusable mistake" in a support page update. The company, a leader in peripherals with quarterly sales hitting $1.19 billion in Q2 FY2026 (up 6% year-over-year), promised a swift fix.

Logitech's Epic Fail: Expired Certificate Bricks Millions of Mac Mice and Keyboards By January 7, patches were rolled out for macOS versions 13 (Ventura) through 26 (Tahoe), requiring manual downloads since the apps' auto-updaters were also crippled by the expiry. Users on older systems were told fixes would come "at a later time."

This isn't Logitech's first rodeo with certificate woes. A similar outage hit in October 2023, when an expired cert broke Logi Options on Macs, forcing temporary workarounds like date rollbacks. History repeated itself, highlighting a glaring oversight for a company that gained market share in pointing devices last year, with sales jumping 13% in Q2 FY2026.

Community-suggested fixes echoed the past: rolling back the system clock (which breaks SSL connections and iCloud sync), or installing an older version like 1.60.495862 via Homebrew or direct ZIP downloads.

The deeper problem, however, lies in the "enshittification" of modern hardware software — a term coined by Cory Doctorow to describe how once-simple tools bloat into internet-dependent behemoths. Logi Options+ isn't just a settings app anymore; it's a full-fledged ecosystem with AI integrations like ChatGPT plugins, "magic macros," and a marketplace for add-ons.

Newer models like the MX Master 3S and 4 mandate it for advanced features, turning local button remapping into a server-validated ordeal. One server hiccup or cert lapse, and your device is neutered — much like single-player games requiring always-online DRM.

Logitech's Epic Fail: Expired Certificate Bricks Millions of Mac Mice and Keyboards As of January 8, 2026, the patches have restored functionality for most users, but the incident lasted over 12 hours, disrupting workflows globally.

With the wireless mouse market projected to grow from $3.1 billion in 2025, Logitech's dominance (bolstered by ergonomic leaders like the MX line) comes with responsibility.

This fiasco serves as a stark reminder: in an era of connected everything, forgetting the basics can brick millions of devices overnight. For Mac users, it's a call to demand simpler, offline-capable software — before the next "oops" moment strikes.
