After releasing developer betas 6 earlier today, Apple is now rolling out iOS 27 public beta 4, alongside corresponding updates for some of its other platforms. Here are the details.

Apple just rolled out:

  • macOS 27 Public Beta 4 (Build 26A5416a)
  • tvOS 27 Public Beta 27 (Build 24J5353b)

The release comes just hours after the company rolled out their corresponding beta 6 versions, introducing bug fixes and performance improvements as Apple fast approaches the official release date of these systems in a few weeks.

The build number for each public beta is the same as that of its corresponding developer beta 6.
