Apple releases macOS 15.4 with redesigned Mail app, AI features and improved Photos app
Coinciding with the release of iOS 18.4, Apple has also just released macOS 15.4. The approximately 6.2 GB operating system update finally allows Mac users in certain languages (such as German) to use Apple Intelligence without having to switch the system language to English. Apple's AI features are now able to generate emojis and images as well as summarize and paraphrase text, among other things.
Apple Intelligence is available on all Macs with an Apple M1 or newer, up to the current MacBook Air with Apple M4. The update also introduces a number of new AI functions, such as the ability to generate reminder videos in the Photos app based on a description. Apple has given the Mail app a fresh design, based on the iPhone's Mail app. Important emails can now be recognized and highlighted using AI.
The update adds new options for hiding or sorting photos in the Photos app, as well as a retouching brush for more precision when using Apple's AI eraser. Matter-compatible robot vacuums can now be controlled directly from the Home app. The update also introduces a new Podcasts widget and improves the performance of Final Cut Pro on the new Mac Studio with Apple M3 Ultra.
Here are all the new features in macOS 15.4:
This update introduces the ability to create Memory movies in Photos with Apple Intelligence, a new Sketch Style option in Image Playground, Mail Categorization, and enhancements to better organize and filter your library in Photos.
