Your anti-malware software may not work if you upgraded to the new operating system. But Apple says a fix is on the way.
If you use a security scanner on your Mac and you update to macOS Ventura, check the program directly to see if it's flagging an error. The workaround to fix the problem is simple once you know to do it. In System Preferences go to Security & Privacy, then the Privacy tab, and then Full Disk Access. Click the lock icon in the lower-left corner of the screen and authenticate with your system password to allow changes.
Researchers noticed—and Apple confirmed to WIRED—that the bug doesn't happen when large organizations use Apple's “mobile device management” program to upgrade their fleet of devices to Ventura. This is significant, because if the bug carried over to managed enterprise devices, it would mean yet another reason for companies to put off important software updates.
“Users were understandably asking me, ‘Why does your tool need that?!’ And I'm like, ‘Uh, I have no idea. It doesn't!’” Wardle says. “It shows that when Apple is pushing out security fixes for reported bugs, they're still struggling to do that comprehensively and successfully without breaking other things. And in this case, they’re shipping a version of their operating system that is breaking security tools for millions, if not tens of millions, of users.
