MacOS 10.15 Catalina arrived in early Octoberbringing new apps for music, Apple TV, and podcasts to Mac owners.”
Catalina also includes a new “Sidecar” feature that extends or mirrors the desktop to an iPad running iOS 13 serving as a secondary display. This apparently only works “officially” on specific Macs, like the 2018 MacBook Air and the 2019 Mac Pro, thoughusers can enter a lengthy Terminal commandto enable Sidecar on older Macs:
defaults write com.apple.sidecar.display AllowAllDevices -bool true; defaults write com.apple.sidecar.display hasShownPref -bool true; open /System/Library/PreferencePanes/Sidecar.prefPane
Other new features spied in Catalina include weak password warnings in Safari, a “block sender” tool in the Mail app, an updated Reminders app, larger photo previews, colored tints covering your entire screen, a new Apple ID location in System Preferences, and more.
The removal of iTunes may be a big surprise for Mac owners after the update. Rather than cram your entire media library into a single place, you can now access albums in the Music app and your TV shows and movies on the Apple TV app. Users can still purchase media through these apps, or enable the iTunes Store interface by clicking the app’s name in the menu bar followed byPreferences.
A previous report suggests thatMac owners may want to hold offon the Catalina upgrade. Many users now report of missing or incomplete messages after its installation. Others claim moving emails between mailboxes results in blank messages.
