Apple rolled out the macOS Sequoia 15.3 Developer Beta 1 on Monday, alongside beta updates for its other devices. In addition to system improvements and bug fixes, it introduces a key feature which is part of Apple Intelligence — the company’s artificial intelligence (AI) suite. Following the update, beta testers can take advantage of Genmoji on their Mac and create custom emojis based on prompts, or those inspired by their family or friends.
