Yesterday Apple shipped developer beta 1 for macOS Tahoe 26.4, and now that same release is available for public beta testers too. Here’s what’s new.
What’s new in macOS Tahoe 26.4 public beta
If you want to get advance access to the next macOS software update, you can do so by joining the free public beta program at beta.apple.com.
New today for public testers is macOS 26.4 beta 1, which is the exact same software released yesterday for developers.
macOS 26.4 comes with four main changes so far.
Battery Charge Limit is now available. Just like the similar iOS option, the new feature lets you set your Mac’s maximum charge to anywhere from 80% to 100%.
If you’re a Safari user, the compact tab bar has returned to System Settings. It was removed from the first version of macOS Tahoe.
New warning popups notify users when a Rosetta app is launched as a reminder that those apps will no longer be supported in macOS 27. Apple has previously confirmed that macOS 26 is the last release that will be available for Intel Macs.
Finally, Apple’s release notes say that the corner radius bug first introduced in Tahoe has been fixed in this update. They say, “Fixed: Window resize pointer does not follow the window’s corner shape.”
The notes for macOS 26.3 similarly said it was fixed, but that was later revealed to be a mistake.
