In September, Apple released a new version of the computer operating system, called macOS 15 or Sequoia, which trashed the functionality of several cybersecurity products, among them one made by CrowdStrike and Microsoft.

Three weeks on from that date, on Friday, Apple issued the first update to macOS 15, and says it fixes those issues. The macOS 15.0.1 release notes claim the update "enhances compatibility with third-party security software."

Apple flagged that update in an email Thursday to TechCrunch but wouldn't comment further for this story.

He is actually DoubleYou's founder, longtime expert on Apple security, and developer of several free security tools for macOS. Patrick Wardle wrote on X, "The release includes a fix for the networking issues that had plagued the initial macOS 15 release."

And to any Apple apologist who blamed 3rd-party vendors, you deserve to be slapped with a large trout as this was an Apple bug reported before GM [golden master]," Wardle said, referring to the first public release of the macOS 15 software.

According to reports that several cybersecurity experts encountered issues trying to use some security tools, including CrowdStrike's Falcon and Microsoft Defender, once Apple launched its macOS 15.
CrowdStrike spokesman Kevin Benacci at this moment pointed out that "waiting for a macOS Sequoia update" is the reason the company waits for before allowing its cybersecurity products to run natively on Apple's operating system.

According to developer and cloud engineer Ugur Koc of cloud managed service provider Glueckkanja, who commented on X about this new macOS update: "It looks like this version finally fixed the problem with [Microsoft] Defender for Endpoint and other antivirus solutions. The problem was that the network filter was blocking internet access."
 CrowdStrike and Microsoft did not comment on this story.
