### Apple Launches Third Developer Beta of macOS 26.4: What to Anticipate
After a one-day delay relative to its peers, Apple has commenced the rollout of the third developer beta of macOS 26.4. Here’s what to anticipate.
#### No Overhauled Siri, but Appreciable Additions Regardless
In the initial two betas of macOS 26.4, Apple rolled out several enhancements to user experience, such as the Charge Limit feature, allowing users to impose a charging limit between 80% and 100%, alongside the reintroduction of Safari’s compact tab layout.
macOS 26.4 also alerts users whenever they launch a Rosetta-based application that its support will cease in a future update. Apple has previously indicated that its translation layer from Apple Silicon to Intel will be phased out by late 2027. Now, in 26.4, this notification appears as a pop-up, likely aimed at urging developers to refresh their applications.
Moreover, Apple has been addressing the corner radius glitch where the resize cursor fails to align with the window’s corner design. Initially marked as a resolved issue in macOS 26.3, it was subsequently updated to reflect it as a “known issue.”
The release build for today’s macOS 26.4 beta 3 is 25E5223i. A deeper examination of the code might uncover additional features.
