In recent news, Apple’s macOS Sequoia update has caused a stir among users due to major compatibility issues with popular security tools. The update, version 15 of macOS, has created disruptions for users who rely on security software from well-known providers like CrowdStrike, SentinelOne, ESET, and Microsoft. This incompatibility has left users frustrated as they navigate through the challenges posed by the update.
The macOS Sequoia update was officially launched on Monday by Apple, introducing new features like Apple Intelligence, which utilizes Apple silicon to enhance language, images, and actions across various applications. Despite the innovative features, users have been facing hurdles with their security tools post the installation of Sequoia.
Reports from multiple sources, including security researchers and social media platforms like Reddit and Mastodon, have highlighted issues with the compatibility of security tools with macOS Sequoia. Security researcher Will Dormann pointed out firewall-related and DNS issues caused by blocking incoming connections within the macOS Sequoia firewall. This issue has affected browsers like Google Chrome, where large downloads stall when incoming connections are blocked.
Despite the growing concerns raised by users and security experts, Apple has not yet provided a clear solution regarding the compatibility issues with Sequoia. As a result, most companies have advised their users against updating to macOS Sequoia until a fix is released. CrowdStrike, one of the major vendors affected, has acknowledged the issue and postponed their support for Sequoia until Apple addresses the problem.
Similarly, ESET initially reported network connection problems following the update but later confirmed that their products are compatible with Sequoia. SentinelOne also made statements advising users against updating to Sequoia initially, only to later clarify that full support was available. However, users continued to face challenges with firewalls and DNS configurations despite the reassurances.
Security researcher Wacław Jacek shared a potential workaround on his blog, suggesting the use of command-line tools to adjust firewall settings for specific applications. Users are advised to proceed with caution when considering updating to macOS Sequoia, especially if they heavily rely on third-party security software.
Mr. Mayuresh Dani, Manager of Security Research at Qualys Threat Research Unit, emphasized the importance of thorough testing by security vendors before deploying updates. He advised security teams to avoid updating to macOS Sequoia unless officially certified by their security vendor and recommended turning off auto-updates to major OS releases.
In conclusion, the ongoing compatibility issues with macOS Sequoia highlight the importance of comprehensive testing and preparation before updating operating systems. Users are encouraged to exercise caution and seek alternative security measures until the compatibility issues are fully resolved. The situation serves as a reminder of the need for organizations to implement a multi-layered security approach to enhance overall stability in the face of unforeseen challenges.
