Yesterday Apple released the fourth public beta of iOS 13, iPad OS 13, and tvOS 13. Today, Apple has launched the fourth public beta for macOS Catalina. It is also worth noting that the third macOS Catalina public beta was launched two weeks ago.
If you are already running macOS Catalina developer beta on your Mac, you can grab the latest beta by going to System Preferences -> Software Update.
macOS Catalina Features
Apple has finally extended Screen Time to macOS. Screen Time is an extremely useful utility that helps keep track of time spent on apps and lets us set limits on screen time.
Screen Time settings are synced across all devices so any limit you apply will be applicable for your usage across all Apple devices you own. Screen Time on macOS Catalina is gaining a useful new “One more minute” feature that will give users an extra minute when their time limit expires to save their work or game.
If you own an iPad, you can now use it as an extended monitor for your Mac. Or you can mirror your Mac’s display content on the iPad. This feature has been replicated by many third-party apps for Mac and with Catalina, Apple is natively adding it to the OS. For someone on the go, Sidecar allows them to turn their iPad into a portable external monitor for their Mac.
More Secure Gatekeeper
Apple focuses on improving the security of its OSes with every new update. macOS Catalina is no different in this regard. Gatekeeper in macOS Catalina now checks all apps for security issues and it also requires apps to get the required permission before user documents can be accessed.
Macs with T2 Security Chip also gain Activation Lock which will essentially render them useless if they are ever stolen or lost.
