macOS 10.15 Said to Feature ‘Luna Display-Like’ Desktop Extension Functionality

macOS 10.15 will have a new feature that allows users to send any window of any app to an external display, according to 9to5Mac's Guilherme Rambo. The external display can supposedly be a monitor connected to the Mac or even an iPad.

The report claims this functionality will be accessible via a new menu that can be opened by hovering over the green "maximize" button in a Mac app window for a split second. The menu is expected to provide options for making windows full-screen, tiling windows, and moving windows to external displays.

The feature, codenamed "Sidecar," is said to be similar to the Luna Display hardware solution that turns an iPad into a second display for the Mac.


Users with an iPad that supports Apple Pencil will be able to draw with the Pencil when the iPad is being used as an external display for the Mac, effectively "turning the iPad into a Wacom-like tablet," according to the report.

The report claims Apple is also working on options that will allow windows to be easily snapped to one side of the screen.

macOS 10.15 Expected to Feature Standalone Music and Podcasts Apps and Redesigned Books App

The report also claims that the existing Books app on Mac will be redesigned to look more like the Apple News app on Mac.

Like the Apple News, Home, Stocks, and Voice Memos apps on macOS Mojave, Rambo says the new Music, Podcasts, and TV apps will be built with Apple's so-called Marzipan developer tools, which allow for a single app to be designed to run across iPhone, iPad, and Mac with a similar codebase.

Despite the standalone Music and Podcasts apps, Rambo says iTunes will stick around on the next major macOS release, as it is still used for some legacy purposes like manual syncing of older iPhones, iPads, and iPods.

Apple's plans to bring UIKit-based Music, Podcasts, and possibly Books apps to the Mac were first hinted at by developer Steve Troughton-Smith on Twitter last week. Apple should unveil macOS 10.15 alongside iOS 13, watchOS 6, and tvOS 13 at WWDC 2019, which kicks off on June 3 in San Jose.
