New macOS Sequoia update reportedly not playing nice with VPNs and cybersecurity tools like Crowdstrike

It’s a big week for Apple. The new iPhone 16 line hits store shelves today alongside the new AirPods 4. Just a few days earlier, Apple released the new iOS 18 and macOS 15, also known as macOS Sequoia, too.

However, Mac users are reporting some issues as it pertains to the latter release and the cybersecurity tools that they use.

As noticed by TechCrunch, Mac users who upgraded to macOS Sequoia are experiencing issues with their cybersecurity software and its compatibility with Apple’s new operating system.

Cybersecurity tools reportedly clash with macOS Sequoia

The issue with macOS Sequoia not playing nice with cybersecurity tools was first discovered after some Mac users who upgraded reported that they were experiencing network connection issues on social media.

The errors were solved when users turned off cybersecurity tools from companies like Microsoft, CrowdStrike, SentinelOne, and ESET.

In addition, BleepingComputer also discovered reports of Mac users having issues with utilizing VPNs on macOS Sequoia as well. The cybersecurity news outlet noted a change in macOS Sequoia’s release notes that could point to the potential problem. 

It appears that Apple removed a feature in macOS’s firewall, which may have broken these applications. The firewall issue appears to be affecting some users’ Firefox web browser too.

Obviously, turning off antivirus software or firewalls is not an ideal solution. Companies like CrowdStrike and SentinelOne are recommending that users not upgrade to macOS Sequoia until the issues are resolved.

While many Apple Mac consumers may not be affected by these specific issues as they don’t use these products, it’s important to note how any new software launch can result in issues on day one.

Be cautious and check with the developers of your essential everyday use applications regarding any compatibility issues before upgrading.
