Compatibility Challenges with macOS 15
Apple’s recent launch of macOS 15, dubbed Sequoia, has not unfolded without its share of complications, particularly for security tool vendors. Reports indicate that the new operating system is grappling with significant compatibility issues, raising concerns among users and IT administrators alike. Notably, it seems that Apple was aware of these challenges prior to the release, yet opted to proceed with the launch nonetheless.
Mac users are advised to consider postponing the upgrade, as the latest OS version has been linked to notable disruptions with anti-malware applications and other essential security tools. While third-party vendors have been proactive in providing temporary solutions, Apple is currently investigating the underlying issues to formulate a more permanent resolution.
After transitioning to macOS 15, numerous users have encountered difficulties with security software from prominent companies such as CrowdStrike, Microsoft, and ESET. Security expert Patrick Wardle highlighted that Apple had been alerted to these compatibility concerns before the official release of Sequoia, yet the decision was made to move forward. As a result, vendors are now issuing advisories, leaving users and IT professionals to navigate the ensuing complications.
The crux of the compatibility dilemma appears to stem from modifications in macOS 15’s network stack. A representative from CrowdStrike confirmed that Apple implemented extensive changes in this area, complicating the path to straightforward fixes. “Please trust me when I say this was looked at through every angle, to see if there was any way to continue to provide the best protection to our customers on this new OS without having to delay,” the representative stated.
Further complicating matters, Microsoft’s bulletin pointed out an unusual issue with the system firewall in macOS 15. When stealth mode is activated, Sequoia becomes unresponsive to “ping” requests, effectively hindering further connection attempts. As a workaround, Microsoft recommends temporarily disabling stealth mode either through the OS settings or via a compliance policy.
Initially, Slovak security firm ESET cautioned customers against updating due to the networking stack issues associated with Sequoia. However, ESET has since achieved full compatibility with macOS 15. Other security software, however, still requires updates to function seamlessly, and users have reported additional challenges with the Firefox browser and other network-dependent applications.
According to Wardle, Apple has acknowledged the networking issues following outreach from several major software vendors. It appears that some unintended changes in Sequoia have led to these disruptions, and Apple engineers are actively working to address the situation. The precise cause of the compatibility problems remains uncertain, whether it be linked to the firewall or a more profound issue within the OS’s networking infrastructure.
As Wardle aptly noted, “If you pride yourself on building secure systems, you can’t push out software that breaks security tools.” This sentiment underscores the importance of thorough testing and compatibility assessments in the tech industry, especially when it comes to safeguarding user data and maintaining system integrity.
