Apple’s latest macOS update, Sequoia (version 15), is causing significant compatibility issues with major security tools, raising concerns for IT professionals and individual users alike.
Several security vendors, including CrowdStrike, SentinelOne, ESET, and Microsoft, report their tools are inoperable on macOS Sequoia. The update is causing firewall-related and DNS issues, affecting network connections and even some browser functionalities.
Most affected companies are advising users not to update to Sequoia until the issues are resolved. IT professionals managing macOS environments may want to delay updating to macOS Sequoia until your security vendors confirm compatibility. This may also involve disabling auto-updates for major OS releases to prevent unexpected issues.
This situation, following on the recent CrowdStrike issues make a good case for companies toImplement a testing process for any new OS releases using dev and beta builds before wide deployment.
And as much as there is a move to reduce the number of tools used in cyber security this may force companies to buck that trend and consider a multi-layered security approach to reduce reliance on single tools or vendors.
Individual users may want to hold off on updating to Sequoia if you use third-party security software. Regarding the official fixes, stay informed through your security vendors’ channels. Do not leverage third party sites for fixes as these situations are often exploited by hackers.
