Users of macOS Sequoia are experiencing difficulties with networking tools such as VPNs and EDRs after the latest update. This interference has led to SSL failures and connection issues with various security tools like CrowdStrike Falcon and ESET EDR. As a temporary solution, it is recommended that users refrain from updating to macOS Sequoia 15 until a fix is released.
Latest macOS Sequoia Update Disrupts Networking Tools
Reports from Apple Mac users indicate trouble connecting to VPNs and EDR tools on the latest Sequoia release. Problems with firewalls have resulted in SSL failures, impacting web browsing and network utilities like ‘wget’ and ‘curl’. Concerns have been raised on platforms such as Reddit regarding these issues.
Users have also encountered difficulties with VPN connections, including popular services like MullvadVPN and corporate VPN solutions.
Although Apple has not provided detailed information on the issue, it has been identified as an OS glitch affecting firewall settings. A Chromium bug report revealed that macOS Sequoia 15 experienced a regression in firewall functionality, causing the errors.
Application Firewall settings are no longer supported in the property list used by Chromium, leading to connectivity issues.
Apple’s macOS 15 release notes confirm the changes in Application Firewall settings.
Expert Recommendations for Mitigation
Security vendors like Sentinel One and CrowdStrike advise users to hold off on upgrading to macOS 15 until a fix is available. ESET has issued a support article outlining steps to resolve network connection problems on macOS 15 with their products.
Users are encouraged to update to compatible versions of Endpoint Security or ESET Cyber Security and remove the ESET Network filter from system settings to address connectivity issues.
