Apple’s latest operating system, macOS 15 Sequoia, has sparked widespread issues with critical security tools. The update has reportedly disrupted software functionality from vendors like CrowdStrike, SentinelOne, and Microsoft, leaving macOS-focused security professionals frustrated.
Social media platforms have been buzzing with reports of these problems, which are particularly affecting enterprise users reliant on these security problems, reports TechCrunch.
The root of the problem is not yet fully understood, but it seems to be related to major modifications in the networking infrastructure of macOS Sequoia. These changes have caused disruptions for numerous security applications that many companies rely on to safeguard their macOS devices.
The situation has left security vendors searching for fixes while maintaining customer confidence.
One of the first companies to acknowledge the problem was CrowdStrike. A sales engineer from the company informed Mac administrators that CrowdStrike would not be able to support macOS Sequoia on day one, a deviation from their usual quick adaption to new macOS versions.
The company cited issues with Apple’s updated network stack, and despite extensive efforts, it was deemed safer to delay the release of a compatible sensor update.
CrowdStrike has since issued a tech alert to its customers, highlighting the severity of the issue and assuring users that the company is actively working on a fix. However, the company’s stance is that the resolution may require changes from Apple’s side as well.
“We’re also tracking similar issues with other vendors and have feedback and a case in to Apple,” the engineer stated, leaving many in the security community hopeful for a quick patch from Apple.
SentinelOne also took a proactive approach, warning its customers in a Mac-focused Slack channel not to upgrade their systems to macOS Sequoia without a supported agent. This advice followed reports of widespread operational issues with SentinelOne’s security tools post-upgrade. The company has not released a formal statement but is working on resolving the problems.
Other vendors, such as ESET, echoed similar concerns. The company reported network connection issues on macOS Sequoia. Microsoft Defender for macOS has also encountered disruptions, with users reporting issues shortly after updating their machines.
Cybersecurity experts are not happy about this update and its related issues. “I get it, that writing bug-free software is challenging, but maybe if Apple spent less time and money on marketing, and more time on actually testing their software, we’d all be better off,” says security researcher Patrick Wardle.
