There are no changes for Sonoma and earlier macOS, and Sequoia 15.0-15.1.1 will also continue working as before. But 15.2 and later work differently, as explained here.
Did you spot the change that didn’t take place as expected in the 15.2 update this week? It marks the end of the Intel era for Macs.
It’s easy to ensure that SilentKnight won’t inadvertently install an upgrade to Sequoia, but still updates the security data files you want. Here’s how.
You’ve just installed an update to XProtect in Sequoia, so why doesn’t it change the version number? How to fix this common problem.
If your Mac is running Sequoia, it could have no XProtect data at all, or being using version 5272 or 5273 but not 5274; if it’s running Sonoma or earlier, the version could be 5272 or 5274 but not 5273. Simple.
SilenKnight 2.11 addresses issues with Sequoia, and is strongly recommended if you’re going to update from Monday 16 September onwards.
If you’re running any version of SilentKnight before 2.10, you need to update it now for compatibility with Catalina and later, particularly for Sequoia. And there are more essential updates too.
