Screens 4 represents the first paid upgrade since Screens originally launched several years ago. Screens 4 for macOS brings the application closer to feature-parity with Screens for iOS, so if you have been using Screens on your iPhone or iPad, many new Screens 4 features will feel familiar. In addition to features shared with the iOS version, Screens 4 also brings some new Mac-specific features to the table.
File Transfers: Mac-to-Mac file transfers are now supported in Screens 4!
Curtain Mode: Obscure the remote display for privacy.
Groups: Organize saved screens into groups for easier navigation.
Touch Bar Support: Screens 4 supports Apple's new Touch Bar feature included with certain Mac models.
OpenGL Support: Remote displays are now rendered locally using OpenGL, resulting in improved display performance.
Availability Indicators: Saved screens now feature availability indicators. A green dot indicates a computer available on the local network, while a purple dot marks computers running Screens Connect.
Momentum Scrolling: New support for momentum scrolling provides a more comfortable experience for those who prefer it.
Tags: You can now assign keywords to saved screens to help locate them among large collections.
Enhanced Remote Display Selection: Screenshots are now included in the UI to help identify your preferred displays.
Improved URL Scheme Support: Screens 4 now supports RFC 2396.
One-Click User Password: This feature simplifies the Mac log-in workflow for remote sessions.
iCloud Sync: Previously available only to those using the App Store version of Screens, now anyone running macOS 10.12 Sierra or later can leverage the convenience of iCloud sync.
