Experimental features in macOS allow users and developers to test new functionalities that are not yet part of the stable release. These features can provide a glimpse into future updates and offer the opportunity to provide feedback to Apple. This article will guide you through the process of enabling and using experimental features in macOS.

Enabling Experimental Features in Safari

Safari, Apple's web browser, often includes experimental features that can be enabled for testing purposes. Here's how you can enable these features:

1. Open Safari: Launch the Safari browser on your macOS device.
2. Access the Develop Menu: If the Develop menu is not visible in the menu bar, you need to enable it.
   • Go to Safari > Preferences > Advanced.
   • Check the box that says "Show Develop menu in menu bar".
3. Enable Experimental Features:
   • Click on the Develop menu in the menu bar.
   • Navigate to Experimental Features.
   • You will see a list of experimental features that you can enable or disable by clicking on them.

Using Experimental Features in Xcode

Xcode, Apple's integrated development environment (IDE), also provides access to experimental features. These features can be particularly useful for developers looking to test new APIs and tools.

1. Open Xcode: Launch Xcode on your macOS device.
2. Access Preferences: Go to Xcode > Preferences.
3. Enable Experimental Features:
   • Navigate to the Components tab.
   • Look for any available experimental SDKs or tools that you can install.

Enabling Experimental Features via Terminal

For more advanced users, some experimental features can be enabled via the Terminal. Here's an example of how to enable an experimental feature in macOS using Terminal:

1. Open Terminal: Launch the Terminal application.
2. Execute Command: Use the following command to enable an experimental feature. For example, to enable the "Dark Mode" feature in a hypothetical scenario:

   defaults write com.apple.finder AppleInterfaceStyle Dark

3. Restart Finder: Apply the changes by restarting Finder:

   killall Finder

Practical Example: Enabling WebGPU in Safari

WebGPU is an experimental feature that provides high-performance graphics and computation on the web. Here’s how to enable it in Safari:

1. Open Safari: Launch Safari on your macOS device.
2. Access the Develop Menu: Ensure the Develop menu is enabled as described earlier.
3. Enable WebGPU:
   • Click on the Develop menu.
   • Navigate to Experimental Features.
   • Click on WebGPU to enable it.

Conclusion

Enabling experimental features in macOS can provide valuable insights into upcoming functionalities and allow you to contribute feedback to improve these features. Whether you are using Safari, Xcode, or Terminal, the process is straightforward and can significantly enhance your user or development experience.
