Scalable macOS CI/CD infrastructure under the 2-VM SLA limit on high-end hardware

We are looking to scale up our automated testing infrastructure for macOS development. Ideally, we want to create a large-scale testing farm capable of running parallel integration tests across multiple OS versions and configurations.

However, we are running into a major roadblock with the Software License Agreement (SLA) limitation, which restricts the concurrent execution of macOS within virtualized environments to a maximum of two (2) instances per physical host.

This restriction creates a massive bottleneck for high-end hardware. Investing in powerful machines like the Mac Studio or Mac Pro feels entirely inefficient for this use case; their massive core counts and memory capacities are effectively wasted if the host is legally throttled to just two concurrent VMs.

Given this friction, we have a few questions for the community and any Apple engineers tuning in: are there any known plans, official updates, or historical precedents suggesting Apple might revise or remove this 2-VM limit for enterprise testing workflows?

Any insights, policy updates, or architectural recommendations on building large-scale, compliant macOS test farms without underutilizing high-end hardware would be greatly appreciated.

Thank you!
