That was quick. Just a few days after releasing the third public beta for macOS Tahoe 26, public 4 beta is already out. Here’s how to install it.

You probably know the drill: Betas can be unpredictably buggy. Even if something works on one release, it is not guaranteed to work on the next.

Of course, your mileage may vary. But if you decide to install the beta, strongly consider to “install it on a secondary system or device, or on a secondary partition on your Mac”. Otherwise, make sure you back up your Mac before making the jump.

To install, the first thing you have to do is enroll in Apple’s public beta program at . Once you’re done, here’s the step-by-step:

• Open System Settings
• Go to General ⇾ Software Update
• Click the ‘i’ icon next to Beta Updates
• From the dropdown menu in the top-right, select the macOS Tahoe 26 Public Beta
• Hit ‘Done’

Today’s public beta is the same build as developer beta 7 , which was also just released. So expect this version to include plenty of under-the-hood improvements and bug fixes, as Apple reaches the final stretch of beta season before the official release towards the end of next month.
