macOS 15.4 beta 4 now available as public launch nears [U]

Apple has just released macOS Sequoia 15.4 beta 4 for developers. This latest beta version arrives one week after the last beta, here’s what to expect.

Update 4:20 p.m. ET: Public beta 4 for macOS 15.4 is now available too, just hours after the developer beta released.

Beta 4 expected to focus on bug fixes with wide release only weeks away

Last week, beta 3 of macOS 15.4 arrived with minimal changes other than bug fixes and performance improvements.

It’s likely we’ll see more of the same in today’s beta 4 update.

Though there’s still time for Apple to make feature changes before the public release, that window is narrowing.

Apple has said that iOS 18.4 will launch publicly in early April, and macOS 15.4 is expected to arrive at the same time.

macOS 15.4 currently includes a handful of nice additions, such as:

If any additions are found in today’s beta 4 release, we’ll keep you posted.

In the meantime, to update your Mac to the latest beta software, open System Settings ⇾ General ⇾ Software Update. From here, you should see macOS 15.4 beta 4 appear. If it doesn’t, click the ‘i’ button and make sure Beta Updates are turned on.
