Apple has released new security updates for macOS Big Sur and macOS Catalina, although it hasn't gone into details about which security issues they address.

The updates include macOS Big Sur 11.6.4 and macOS Catalina Security Update 2022-002. Both updates are listed on the Apple security updates (opens in new tab) webpage but details are sadly lacking. The only information Apple is offering is that there is no information to be had. "This update has no published CVE entries" is the only text available.

Those who are still running macOS Big Sur or macOS Catalina can download the new security updates via the System Preferences app and I would suggest everyone does exactly that and without delay. Security updates are always worth installing as soon as possible, no matter which version of macOS you happen to be running.

While many people will already be updated to macOS Monterey a large number will be hanging on to older versions of the Mac's operating system for various reasons. Those reasons could be compatibility with apps or features, for example, and it's why Apple continues to release security updates for older versions of macOS.
