Today, we’re excited to announce that macOS Sequoia is now available on Unity Build Automation! This new macOS version comes with Xcode 16.3, 16.4, and 26.0 Beta 2 pre-installed. These versions are currently marked as experimental. The experimental tag will be removed in the coming weeks.
Important Note for Users: The Build Automation team made the decision to only provide the ARM Native version of the Unity Editor when using macOS Sequoia. Builds running on this operating system will only be compatible with Unity versions 2021.3 and higher. Please ensure your projects are using a supported Unity version before initiating builds on macOS Sequoia. If you encounter any issues or have questions, please reach out to our support team.
Edit: Added clarity around ARM support
