Apple has upgraded iMovie and GarageBand for macOS and iOS, and the latter for iOS only. All updates are available at the Mac App Store and Apple App Store.
iMovie 2.2.6 for iOS lets you connect an external display to your iPad or iPhone and choose to mirror the iPad display or preview your video fullscreen while you edit. There’s support for uncompressed 4K video output on the 2018 iPad Pro 11-inch or iPad Pro 12.9-inch.
iMovie 10.1.10 for the Mac Removes the option to share video files directly to Facebook, and adds a new Prepare for Facebook option that exports a Facebook-compatible video file to your system that you can manually upload to the Facebook website. It also improves overall stability.
Pages, Numbers, and Keynote for both macOS and iOS have been upgraded with performance and stability fixes. And the Pages app for both operating systems now lets you publish directly to Apple Books for download or purchase.
