Apple's latest macOS update is causing headaches for security programs

Apple's macOS 15 update causes security software issues, affecting vendors like CrowdStrike, Microsoft, and ESET.

: The latest macOS 15 update from Apple is causing significant compatibility issues for security software. Companies such as CrowdStrike, Microsoft, and ESET are affected, with network stack changes at the root of the problem. Some vendors have provided temporary solutions, while others like ESET have found full compatibility. Apple is aware and working on a permanent fix.

The new macOS 15 update from Apple has led to serious compatibility problems with various security programs. Vendors including CrowdStrike, Microsoft, and ESET have reported issues that disrupt the functionality of their security tools, mainly due to changes in macOS 15’s network stack. Apple was informed of these issues before the release but decided to proceed with the launch anyway. The problems have led to advisories from vendors and frustration among users and IT administrators trying to manage the fallout.

CrowdStrike specifically noted that fixing the issues is not straightforward due to extensive changes in the networking stack. Microsoft identified a strange behavior with the system firewall when stealth mode is enabled. Meanwhile, ESET initially recommended avoiding the update but has since achieved full compatibility, whereas other security tools and even browsers like Firefox continue to struggle.

Apple has acknowledged the networking complications, stemming from unintended changes in the new OS version. Engineers are currently working to resolve these disruptions, though the exact cause remains uncertain. Mac users dealing with network-dependent tools are advised to delay the macOS 15 upgrade until these issues are properly addressed by Apple.
