We recently got to know that Apple is planning to release macOS Big Sur 11.3 next week alongside the upcoming iOS 14.5, tvOS 14.5, and more. However, Apple has seeded the first developer beta of macOS Big Sur 11.4 ahead of macOS 11.3 release next week. While macOS Big Sur 11.3 has a lot in store for users, it has been recently discovered that the company is bringing support for AMD GPU with the forthcoming macOS Big Sur 11.4 release.

If you are a developer, you can get your hands on the latest beta via over-the-air. Make sure that you have installed the proper configuration profile from the Apple Developer Center and the macOS 11.4 beta can be downloaded through the Software Update mechanism in System Preferences. While the company has added numerous additions in macOS 11.3, support for AMD GPUs in macOS Big Sur 11.4 is a welcome addition (via 9to5mac).
