The full and final version of macOS Catalina 10.15.6 is now available for download. You can download the update over the air.

macOS Catalina pales in comparison to what macOS Big Sur brings to the table. It features an all-new design, it's faster, more responsive, and everything screams brand new. But that update is going to arrive later this year, which means you are stuck with macOS Catalina for now. And today, macOS Catalina 10.15.6 is available to download for all compatible Macs and you can grab the latest update over the air without any effort.
