Apple has started rolling out the second public beta of macOS Tahoe 26.4 to beta testers just days after the developer build arrived. This means anyone enrolled in Apple’s Beta Software Program can download and test the latest features ahead of the official public launch expected later this spring.
Here’s a Google Discover-friendly breakdown of what to know 👇
What’s Happening with macOS 26.4 Public Beta 2
• Apple has begun distributing the second public beta of macOS Tahoe 26.4 — the same build previously made available to developers, so public testers are now getting the official early look.
• As usual, this update appears via System Settings → General → Software Update if you’re part of the Apple Beta Software Program.
• Beta releases are meant for testing and feedback — stability isn’t guaranteed, so backing up your Mac before installing is recommended.
Key Features in macOS Tahoe 26.4
Battery Charge Limit
A new Battery Charge Limit feature lets MacBook users set a maximum battery charge between 80% and 100% — helping prolong battery lifespan if you usually keep your laptop plugged in.
Safari Compact Tab Bar
Safari’s Compact Tab Bar is back as an option after some users missed it in earlier versions. This gives a more space-efficient look if you prefer fewer visual elements.
Rosetta Warnings Begin
macOS 26.4 starts showing alerts when users run apps still relying on Rosetta 2 — Apple’s Intel-to-Apple Silicon translation layer — as it continues to phase out Rosetta ahead of macOS 27.
