According to Bloombergs Mark Gurman, Apples new Mail app is going to make its way to the Mac very soon, with macOS 15.4. Apple introduced the new Mail app to the iPhone back in December with iOS 18.2, but it hasnt made its way to any other platform since.Surprisingly, weve already seen what the new Mail app will look like on macOS. Back when Apple introduced the new M4 Macs in October, we got a small look at the new Mail app for macOS in one of the unveilings. This wasnt some groundbreaking leak, since the design had already been unveiled on the iPhone back at WWDC, but it was interesting, since there werent any signs of the new Mail app coming to macOS quite yet.Then, in December, iOS 18.3 and macOS 15.3 beta started rolling out. While macOS 15.3 did bring Genmoji to macOS, it didnt bring the new Mail app to the Mac, leaving many wondering when itd debut.However, according to Gurman, this will be changing very soon with the upcoming macOS 15.4 release, which will likely enter beta in the coming weeks, and debut in April:But theres another, more under-the-radar feature coming in April as well: The Mac will get the upgraded Mail app that uses AI to prioritize messages and sort content into different inboxes. Right now, iPad and iPhone users are able to tap into the feature which is terrific but Mac customershave been left behind. That changes with macOS 15.4, Im told. For those not familiar with the feature:It sorts mail into aprimary category, as well as ones for transactions, promotions, updates and all mail.Gurman states that the new Mail app is currently available for iPad users, though that isnt actually the case quite yet, neither in iPadOS 18.2 nor iPadOS 18.3. Hopefully, we see the new Mail app debut for iPad users soon, with the release of iPadOS 18.4. Only time will tell.Are you excited for the new Mail app to expand to other Apple platforms?
