Apple Launches 4th Developer Beta Versions for iOS 26.1, macOS Tahoe 26.1, and iPadOS 26.1

Today, Apple unveiled the fourth beta versions of its operating systems for developers, a release that came slightly later than anticipated. The delay is likely due in part to ongoing issues associated with AWS, affecting the scheduling of these updates.

Latest Developer Beta Releases from Apple

As part of its routine software development strategy, Apple routinely issues several developer beta builds leading up to the final versions intended for consumer use. The fourth iteration of these beta builds is now available for the following operating systems:

iOS 26.1 Beta 4
iPadOS 26.1 Beta 4
watchOS 26.1 Beta 4
macOS Tahoe 26.1 Beta 4
visionOS 26.1 Beta 4
tvOS 26.1 Beta 4

These updates frequently include minor improvements rather than major overhauls. For instance, the first developer build of iOS 26.1 introduced a suite of enhancements:

Enhanced Apple Intelligence with support for Live Translation across Chinese, Japanese, and Korean.
New Model Context Protocol (MCP) enabling third-party AI agents to interface seamlessly with Apple services and device data.
Refinements to the Liquid Glass effect on the dialer keypad.
A dedicated scrubber feature for managing photos and videos.
Swipe functionality for album track changes in Apple Music.

The preceding third developer build also rolled out some noteworthy features, including:

A redesigned Apple TV icon.
Settings for notification forwarding options.
References to a yet-to-be-released wallpaper.
Hints about forthcoming third-party AI integrations.
An extension of the Local Capture feature from iPadOS to iOS, enabling users to record audio and video during video calls.

The latest fourth beta build for iOS 26.1 includes the option for users to adjust the opacity of the Liquid Glass effect, enhancing customization capabilities.
