You really really really need to update your Mac. Like really

While everyone was talking about the arrival of Apple Intelligence in the iOS 18.1 and macOS 15.1 betas, Apple also delivered a series of updates for its existing operating systems. And if you own a Mac, you should absolutely install it right away.

The updates don’t include any notable new features, but they do fix a lot of security vulnerabilities. In all, the updates include more than 100 security patches for macOS Sonoma (14.6), Ventura (13.6.8), and Monterey (12.7.6). When you install them, there will be 54 updates for Sonoma, 36 for Ventura, and 32 for Monterey. That’s an incredible amount of patches, especially considering the last round of updates only arrived in mid-May.

There are far too many to list here, but some of the highlights that jump out as particularly concerning:
