If you’ve been waiting for the latest update to macOS, here’s your chance: Catalina is available for download now.

The new OS was officially revealed this June, with the public beta coming out later the same month. Today it rolls out, a little later than is usual for Mac updates (which typically come out in late September), but still welcome all the same.
