How fast is a macOS VM, and how small could it be?

⚡️ Speed & Size of macOS VMs



Running a macOS virtual machine (VM) efficiently requires a delicate balance between speed and size, with practical implications for developers and power users who need to test macOS-specific software or work within resource-constrained environments. By optimizing VM configurations, users can achieve surprisingly fast performance even on limited hardware, while minimizing storage usage.
