On Monday, Apple rolled out its latest operating system update, macOS 15, also known as Sequoia. However, this update has unintentionally disrupted the functionality of several cybersecurity tools made by prominent companies such as CrowdStrike, SentinelOne, Microsoft, and others. Social media posts and messages in a Mac-focused Slack channel reveal widespread frustration among users and security experts alike.
The Problem: Affected Security Tools and Unclear Causes
The exact issues stemming from the macOS Sequoia update are still unclear, but it appears to impact numerous security products used by macOS users and enterprises. The problem has caused frustration for developers of macOS security tools, who are now being blamed for the malfunctioning software, despite the root cause being Apple’s changes in the OS.
Expert Opinion: Developers Frustrated by Apple’s Lapses
Patrick Wardle, founder of Mac and iOS security startup DoubleYou and a well-known macOS security expert, voiced his concerns:
“As a developer of macOS security tools, it’s incredibly frustrating to deal with upset users blaming your tools for breaking their Macs, when in reality, it was Apple’s fault all along,” Wardle said. He added, “Maybe if Apple spent less time and money on marketing, and more time on testing their software, we’d all be better off!”
Delayed Response from Security Vendors
On the day of macOS Sequoia’s release, a CrowdStrike sales engineer mentioned in a Mac admins Slack group that the company had to delay its support for the new macOS version. The engineer shared,
“I’m very sorry to report that we will not be supporting Sequoia on day 1 in spite of our intention (and previous track record) to support the latest OS within hours of General Availability.”
The engineer further explained that CrowdStrike had issued a “Tech Alert” to its customers, highlighting network stack changes introduced by Sequoia. The company is currently working on a fix, but the engineer noted that a patch from Apple is unlikely, meaning that CrowdStrike will need to address the issue internally with a sensor release.
Broader Impact on Security Tools
macOS Sequoia seems to have introduced significant system changes, particularly affecting how the OS interacts with network security tools. This has left many enterprise users frustrated, as their essential cybersecurity tools from CrowdStrike, SentinelOne, and other vendors are no longer functioning correctly.
While security vendors are working diligently to address the issue, the disruption highlights the risks associated with upgrading to a new OS version without confirmed compatibility from key software providers.
Conclusion: Apple’s Testing Process Under Scrutiny
The macOS Sequoia update has once again raised questions about Apple’s testing processes before releasing new operating system updates. For now, macOS users, especially those relying on enterprise-level security tools, are advised to proceed with caution until a fix is available.
As security vendors rush to resolve the issues, it remains clear that untested software updates can cause major disruptions in the enterprise landscape, highlighting the importance of close coordination between OS developers and security tool vendors
