Apple has quietly but importantly begun testing a new version of its operating systems — iOS 26.6, iPadOS 26.6, watchOS 26.6, and macOS 26.6. There are no grand presentations, but behind the scenes, work is underway on critical security and stability updates.
This is not an update that will bring new features or visual changes. The main goal is to prepare devices for the upcoming WWDC 26 conference, where the company will likely unveil new gadgets. Apple engineers are focused on internal optimization to ensure seamless performance of future devices.
New warning about call blocking limits
In the first test build for iPhone, one notable new feature has been discovered — a system notification that warns users when they are approaching the limit of blocked numbers. This may be useful for those who frequently encounter annoying calls and use the call-blocking feature.
How to test iOS 26.6 without a paid subscription
Good news for enthusiasts: Apple has opened access to test builds without requiring a paid developer account. Now, any user can become part of the testing process.
To do this, you need to:
- Download the Apple Developer app from the App Store.
- Open it and go to the “Account” section.
- Enter your regular Apple ID credentials.
After that, your smartphone will automatically be added to the list of test devices. The feature may not appear in settings immediately — sometimes you need to wait a few minutes after registration.
If you want access to the earliest developer builds, you will need the appropriate account. However, even without it, you can participate in testing using free tools like Xcode or the mobile app.
