It's not uncommon for new operating system updates to cause a stir, but Apple's latest macOS 15 has raised eyebrows for a different reason. The update is reportedly causing serious compatibility issues for security tool vendors, leaving users and IT admins scrambling to find a solution. The problem appears to be rooted in the updated network stack, which has made it difficult for security software to function properly.

The issue was first noticed by security expert Patrick Wardle, who claims that Apple was alerted to the problem before the update's release. Despite this, Apple chose to move forward with the update, leaving security vendors and users to deal with the fallout. Wardle notes that if you pride yourself on building secure systems, you can't push out software that breaks security tools.

The affected security software includes CrowdStrike, Microsoft, and ESET, with some vendors issuing advisories and workarounds to help users navigate the issue. Microsoft suggests temporarily disabling stealth mode in the system firewall, while CrowdStrike is working on a permanent fix. ESET has managed to achieve full compatibility with the update, but other security software still requires updates to function properly.

The exact cause of the problem remains unclear, with some speculating that it may be related to the firewall or a deeper-level issue within the OS's networking stack. Whatever the reason, it's clear that Apple is aware of the issue and is working to resolve it. In the meantime, users may want to exercise caution when updating to macOS 15, or consider delaying the update until a permanent fix is available.
