Apple's OS once again is causing issues as macOS 15 Sequoia is causing network connections errors. But is there anything users can do right now?

Apple released macOS Sequoia on Monday, but the update has broken the functionality for some networking and security tools from companies such as Microsoft, CrowdStrike, SentinelOne, and more, as Bleeping Computer reports. Affected users on Reddit are sharing their issues with security software such as ESET Endpoint Security and CrodStrike Falcon.

Recommended Videos Bleeping Computer saw a non-public bulletin where CrowdStrike encouraged users not to upgrade to macOS 15 by saying, “Due to changes to internal networking structures on macOS 15 Sequoia, customers should not upgrade until a Mac sensor is released that fully supports macOS 15 Sequoia,” reads the customer-only CrowdStrike bulletin.” SentinelOne Support gave their users the same advice.

VPNs are no strangers to the issue since users have also reported problems with Mullvad VPN and corporate VPN. But Proton VPN has managed to steer clear of the issue and is running smoothly on the latest macOS 15 release. Apple has not officially commented on the cause of the problem, but according to a macOS 15 release note seen by Bleeping Computer, an outdated feature in macOS 15’s Firewall may be to blame.
