How to Install macOS Tahoe Public Beta 3

Apple has made the third macOS Tahoe public beta available for testing before the new Mac operating system's official release in the fall. Keep reading to learn whether you should install it on your Mac, and if so, how to go about it.

Getting access to the macOS Tahoe public beta is simple, and can be done by enrolling your Mac in Apple's free Apple Beta Software Program. The steps you need to complete to install the software on your Mac are provided towards the end of this article, but before you jump ahead, here are a few things worth considering.

Should I Install the macOS Tahoe Public Beta?

With macOS Tahoe, Apple introduces a major redesign for the platform with the all-new Liquid Glass interface, along with a host of new features. These include the Phone app on Mac, powerful new Spotlight actions, further Apple Intelligence integration, a dedicated Games app, and customizable backgrounds in Messages. Live Activities from iPhone also make their way to your Mac's menu bar, which now has a fully customizable Control Center. With so many additions and a striking visual update, it's no surprise that macOS Tahoe is generating a lot of interest among Mac users.

But before you commit, bear in mind that Apple does not recommend installing macOS beta updates on your main Mac. Remember, this is beta software, which means there are almost certainly bugs and issues that can prevent software from working properly or cause other problems with the system. Indeed, one of the reasons that Apple releases the beta to developers early is so that they can feed back problems and help Apple debug them. If you have a spare Mac hanging around, by all means use that, otherwise consider holding off until the general release in the fall.
