MacBook Air running macOS
Apple has seeded a second release candidate for macOS Sequoia 15.4, as the updates to the company’s operating systems get closer to a public release.
Apple initially introduced the first round of release candidates for macOS 15.4, iOS 18.4, iPadOS 18.4, tvOS 18.4, watchOS 11.4, and visionOS 2.4 on March 24. Three days later, it has introduced a second RC build of macOS 15.4 to test out.
It’s not uncommon for there to be multiple release candidate builds of software before it is released to the public. While a release candidate is supposed to have the same content as the final release, sometimes there is a missing or incorrect element that needs addressing urgently.
The original RC build was 24E246, which has now been replaced by 24E247.
Apple has not yet disclosed details of what has changed between the RC builds, but it is likely to be a bug fix, one which could’ve appeared in the first RC build.
The update to macOS 15.4 brings with it a number of changes, including Apple Mail getting Apple Intelligence sorting, and support for more languages in Apple Intelligence, among other features.
Testers can update macOS by opening System Settings, selecting General, then Software Update, followed by selecting Update Now or Update Tonight.
