macOS Sequoia’s firewall disrupts security tools, and more
Apple’s recent macOS 15 update, also known as Sequoia, has caused compatibility issues with several security tools from prominent vendors like CrowdStrike, SentinelOne, Microsoft, and others. Users on social media and Mac-focused forums have reported disruptions in the functionality of these security applications following the update.

At this point, it’s unclear exactly what is the issue, but it appears to affect several products made by companies that provide software for macOS users and enterprises, which has caused frustration among people who work on and with macOS-focused security tools.
“As a developer of macOS security tools, it’s incredibly frustrating to time and time again have to deal with (understandably) upset users (understandably) blaming your tools for breaking their Macs, when in reality it was Apple’s fault all along,” said Patrick Wardle, the founder of Mac and iOS security startup DoubleYou, and a longtime expert on macOS security.
Security researcher Will Dormann wrote on Mastodon that he was having issues with DNS and running his firewall on his macOS machine. Another security researcher, Wacław Jacek, wrote in a blog post that, “it seems the OS firewall can sometimes start blocking access to web browsing after upgrading to macOS Sequoia,” and shared a potential workaround.
The problems with macOS Sequoia appear to have caused issues with Firefox browser users, too, according to a separate Reddit thread.
MacDailyNews Take: For mission critical Macs, we always wait for the first update, in this case, MacOS 15.1.
