OpenBSD/arm64 has achieved a significant milestone by successfully running as a guest operating system under Apple's Hypervisor. This development, driven by recent commits from Helg Bredow and Stefan Fritsch, addresses long-standing compatibility issues. The updates focus on enhancing OpenBSD's ability to work seamlessly within the Apple Hypervisor environment, ensuring improved performance and stability.

The latest changes include modifications to the viogpu and vio drivers, which are essential for graphics and network functionality. These updates ensure that OpenBSD can handle framebuffer updates and negotiate MTU settings effectively, aligning with Apple's virtualization standards. This advancement is particularly valuable for users of newer Mac models who rely on OpenBSD for their computing needs.

This progress is a boon for developers and users who have been waiting for enhanced support on Apple's hardware. The community is encouraged to test these updates in snapshots and provide feedback, as this will further refine the integration. With OpenBSD now compatible with Apple Hypervisor, users can anticipate improved virtualization performance and broader adoption of OpenBSD in macOS environments.
