It’s something the leaks and rumors leading up to the event discussed as well, and for good reason: One of Apple’s big new “features” this year is simply improving the overall experience of using the company’s devices.

Most of us won’t experience any of these new features—including stability upgrades—until Apple releases the updates in the fall. But, like all software releases, Apple is currently trialing updates like iOS 27 and macOS 27 with developers, as well as any volunteers brave enough to install the unfinished OSes on their devices.

The whole point of a beta, after all, is to root out issues before the update makes it to the general public, so it stands to reason that the very first beta for iOS 27 and macOS 27 would come with the most problems. It’s why I don’t recommend installing the betas on your personal devices, at least not until Apple drops a public beta. The risk for stability issues, including data loss, is usually too great.

Apple’s newest betas actually improve performance on iPhone and Mac for some users

The situation appears to be a bit more complex than in past years, however. Reports from beta testers on forums like Reddit show positive impressions, especially for macOS 27. Take this r/MacOSBeta Reddit thread, for example: OP was surprised by the performance boost in the first macOS 27 developer beta, claiming that the “lag, stutters, and general sluggishness” they were dealing with on macOS 26 Tahoe are largely absent now. They noticed apps launching faster, smoother…
