Logitech fixes macOS mouse malfunction caused by expired software certificate

Logitech has resolved a critical issue affecting macOS users, where several of its mice stopped functioning due to an expired software certificate. The problem, which affected both individual and professional users, highlighted the risks associated with certificate-based software security and the impact of small technical oversights on productivity. Logitech’s swift response ensures that users can return to normal operation without the need for hardware replacement.

The Nature of the Problem

Earlier in 2026, macOS users began reporting that certain Logitech mice, including popular models used for both office work and creative applications, were failing to connect or respond when plugged into Apple computers. The underlying cause was traced to an expired digital certificate in the Logitech software responsible for driver authentication and device management.

Digital certificates are used to validate software integrity and security. When a certificate expires, macOS’s Gatekeeper system, designed to protect users from malicious software, blocks the application from running. In this case, the expired certificate prevented the Logitech Options and Logitech Control Center software from launching, effectively disabling advanced mouse features and, in some cases, basic functionality.

Impact on Users

The issue affected a wide range of macOS users, including professionals relying on Logitech peripherals for design, editing, and programming tasks. Users reported:

• Loss of mouse functionality, including tracking, scrolling, and button mapping
• Inability to customize device settings through Logitech software
• Disruption of productivity, especially in workflows dependent on multi-button mice

The problem caused frustration because it occurred suddenly and appeared unrelated to macOS updates, leaving users with limited immediate remedies.

Logitech’s Response

Upon identifying the issue, Logitech acted quickly to release an updated software package with a renewed certificate. The update restored functionality and resolved compatibility issues with macOS security protocols. Key elements of the fix included:

• New software versions of Logitech Options and Logitech Control Center signed with a valid certificate
• Automatic detection and update prompts to ensure affected devices receive the patch quickly
• Guidance for users on manual installation in cases where automatic updates were not immediately available

Logitech also communicated openly through support channels, explaining the cause of the malfunction and providing detailed steps to restore full functionality.

Lessons on Software and Security Management

The incident underscores the critical role of certificate management in peripheral and driver software:

• Expired certificates can lead to widespread device malfunctions even if the hardware itself is unaffected
• Continuous monitoring and proactive renewal of digital certificates are essential to avoid user disruption
• Transparent communication with users can minimize frustration and maintain trust

Industry observers note that such incidents highlight the importance of robust software maintenance practices, especially for devices integrated into professional workflows.

User Experience After the Update

Following the patch release, macOS users reported that:

• All affected Logitech mice functioned normally, including advanced features like gesture controls, macro customization, and scroll acceleration
• Logitech software now launches without security warnings
• System stability has improved, allowing users to resume normal work without hardware concerns

The swift resolution demonstrates Logitech’s commitment to customer support and reliability, even in situations caused by technical oversights.

Broader Implications for Peripheral Manufacturers

This episode serves as a cautionary tale for the broader peripheral industry. Companies relying on signed software for device management must:

• Maintain rigorous certificate lifecycle monitoring
• Implement automatic renewal and testing procedures
• Provide transparent user guidance when disruptions occur

Failing to do so can lead to productivity losses, negative publicity, and decreased user confidence.

Logitech’s quick resolution of the macOS mouse malfunction caused by an expired software certificate illustrates both the challenges and responsibilities of modern device software management. While the issue temporarily impacted user productivity, the renewed software certificate restores full functionality and demonstrates Logitech’s commitment to quality, reliability, and user trust. Users can now continue using their mice and advanced features without interruption, reaffirming the importance of proactive software maintenance in the era of security-conscious operating systems.
