Apple released an update on Tuesday that includes macOS Ventura 13.6.2 build 22G320 and macOS Sonoma 14.1.1 build 23B81. The former is for older Macs that cannot upgrade to macOS Sonoma and contains bug fixes. The latter is for any Mac already compatible with macOS Sonoma pre-M3, which contains bug fixes and security updates.
And then there's also the macOS Sonoma build 23B2082/22G2321. It is directed at Macs with M3 series chipsets. It seems some of the 14-inch MacBook Pro models with M3 have been ready to ship since early July, which means they have macOS Ventura. For some reason, those Macs can’t upgrade to macOS Sonoma, which should be addressed by the new update.
If you want to manually update your Mac instead of waiting for an automatic update, you can do so by clicking the Apple icon in the main menu. And then select System Settings, click on General, then Software Update, and lastly, the update itself. Make sure you backup your files before updating.
