Select a screen saver from one of the available categories: macOS: These are slow-motion images. (You may need to scroll down.) Open Screen Saver settings for me. Here are a few things to expect as you navigate your way through Catalina. On your Mac, choose Apple menu > System Settings, then click Screen Saver in the sidebar. And as always, back up your machine before you install this prerelease software, so you can restore your Mac to its previous working state if anything disastrous happens. However, it’s still not the final version of the OS, so you can expect bugs and incomplete features if you decide to try it. MacOS Catalina has been available since late last month as a public beta, which means anyone can download it and test it on their own machine. (Even more so if the keyboard on your MacBook works!) But mobile software has its benefits-speed, usability, simplicity-so it’s not a surprise to see that MacOS 10.15 Catalina, the newest operating system for the Mac, borrows some features from its mobile cousin iOS. The iPad may be getting impressively close to Everyday Computer territory, but there is still something about the desktop software experience on a Mac that a mobile device can’t replace.
