Apple has released the first public beta of its new Mac operating system, called Mac Ventura. Ventura is the most solid and reliable public beta I’ve ever tried, but that doesn’t mean you should upgrade to Ventura now. Ventura runs on almost any Mac released in the past five years, and runs on both Intel and Apple Silicon Macs. Ventura also extends Apple’s push to integrate macOS with the iOS and iPadOS operating systems used on the iPhone and iPad, notably in an ingenious new feature that lets you use your iPhone’s camera instead of the one on your Mac. If you’re an IT manager or if you need to test whether your apps work with the new version, install the public beta on a spare machine. . . .
