New benchmarks redefine minimum specifications for macOS virtualisation on Apple Silicon
A fresh review of macOS Tahoe performance indicates the upcoming MacBook Neo could feasibly host a functional virtual environment, provided sufficient storage is allocated
A comprehensive review of macOS virtualisation on Apple Silicon has updated previous performance data and established new minimum resource requirements for a usable virtual machine. Conducted using a Mac mini M4 Pro host running macOS 26.4.1, the testing performed with the Viable virtualiser indicates that a macOS VM can run effectively for everyday tasks with as few as two virtual cores and four gigabytes of RAM.
In high-performance configurations, a guest VM equipped with five virtual cores and 16 gigabytes of RAM achieves 98 per cent of the host's single-core CPU speed and 95 per cent of its GPU performance. While the CPU and GPU metrics remain robust, the virtual neural engine performs significantly slower than the host on half-precision and quantised tests, suggesting that AI-dependent workflows may still face limitations within a virtualised environment.
The study confirms that a macOS 26.4.1 VM remains fully functional for lightweight everyday tasks, such as web browsing and storage analysis, with just two virtual cores and four gigabytes of allocated RAM. In practice, this configuration consumes only 3.1 gigabytes of actual physical memory, demonstrating that the operating system can operate efficiently even with highly constrained resources.
Storage requirements present a critical consideration for potential hosts, as at least 60 gigabytes of free disk space is required to safely accommodate system updates. Although APFS sparse files allow a 100 gigabyte virtual disk to occupy less physical space based on actual usage, allocating a minimum of 60 gigabytes is necessary to prevent update failures and ensure system stability.
These findings suggest that the upcoming MacBook Neo could feasibly run a usable macOS VM, provided the device includes sufficient storage capacity. While previous reviews relied on older performance data and did not establish minimum specifications for a usable machine, this updated analysis provides a clearer picture of the hardware demands for future Apple devices.
The implications for investors and technology watchers are clear: the ecosystem for running macOS in a virtualised environment is becoming more accessible, yet specific constraints around neural engine performance and storage allocation must be factored into hardware design and user expectations.
