Update: iOS 15.1 beta 4 is now available to public beta testers as well.

The iOS 15.1 beta process continues today as Apple is now rolling out iOS 15.1 beta 4 to developers. This comes one week after the last update, which added ProRes support and a new Auto Macro toggle for iPhone 13 Pro and iPhone 13 Pro Max users.

With Apple having scheduled a special event for next week on October 18, we could be just days away from the official public release of iOS 15.1…

Today’s new release of the iOS 15.1 beta 4 is available to developers via an over-the-air update in the Settings app. As usual, if the update does not immediately appear for download, keep checking, as it sometimes takes a few minutes to roll out to all registered developers. The build number of iOS 15.1 beta 3 is 19B5068a. 

As a reminder, here’s a recap of what’s new in iOS 15.1: 

In addition to iOS 15.1 beta 4, Apple today is also rolling out the following new betas:

  • watchOS 8.1 Developer Beta 4 – Build 19R5566a
