Apple has seeded the new watchOS 27 developer beta 4 for Apple Watch, and you can download it immediately over the air.

New watchOS 27 Developer Beta 4 Now Available for Download with Improvements and Performance Fixes

Are you ready for a new watchOS 27 beta? I’m sure you are, because watchOS 27 developer beta 4 is now ready for download to those enrolled in the Apple Developer Program.

If you’re currently testing out the newly released public beta of watchOS 27, you might want to hang tight for a moment. Apple will release the new update for public beta testers very soon with the same changes as the developer beta.

Those who are testing out watchOS 27 beta 3 on Apple Watch, here’s what you have to do in order to download beta 4:

  • Place your Apple Watch on its magnetic charger.
  • Make sure your iPhone and Apple Watch are connected to the same Wi-Fi and have 50% of more battery remaining.
  • Now launch the Watch app on the iPhone.
  • Navigate to General > Software Update.
  • Tap on the Download and Install button when you see developer beta 4.

Once the installation is complete, and it will definitely take some time, you can start using your Apple Watch normally. However, I will recommend keeping your Apple Watch on the charger for a little while longer and let the indexing process complete.

Like I said, the same update will become available for public beta testers later. And, if you’re interested in downloading the developer beta of watchOS 27 on Apple Watch, head over to this link for instructions.

Siri AI was a part of the third developer beta of watchOS 27, and it will be interesting to see if Apple has added something new in this release. If there’s anything worth talking about, I will be back with more updates.
