It's important to ensure you are running one of these supported operating systems before attempting to install and use Safari Technology Preview 223. Older macOS versions may not be compatible.

How to Update or Download Safari Technology Preview

Updating Safari Technology Preview is straightforward for existing users. The update will be offered through the standard Software Update mechanism found within System Preferences (or System Settings on newer macOS versions). Simply check for updates, and the latest version will be downloaded and installed automatically.

If you haven't already installed Safari Technology Preview, you can download it from Apple's developer website. Downloading and using STP does not require a developer account; it's open to everyone interested in testing the latest browser features.

The Purpose of Safari Technology Preview

Safari Technology Preview serves as a vital tool for Apple in its browser development process. By releasing pre-release versions of Safari to the public, Apple gains valuable feedback from both developers and everyday users. This collaborative approach allows them to identify and address potential issues before they reach the final release version of Safari, improving overall quality and user experience.

STP runs independently from the standard Safari browser, allowing you to use both simultaneously without interference. This allows for testing new features and providing feedback without affecting your primary browsing experience. This participatory approach ensures that Safari continually evolves to meet the needs of its user base.

Running STP Alongside Regular Safari

One of the significant advantages of Safari Technology Preview is its ability to coexist peacefully with the standard Safari application. You can have both browsers installed on your system without any conflicts. This is particularly helpful for developers who might want to test new features in STP while continuing to use their standard Safari for everyday browsing.

This feature allows users to seamlessly transition between the latest experimental features in STP and the stable and reliable experience of the standard Safari browser.
