This so going to sound extreme, but it is true: I personally and professionally won’t use it for anything until it has Metal support.

The simple fact is that me and my team do our development largely on MacBook Pros and Mac Studios. We have some GPU rigs for running production code on Lunux or Windows with NVIDIA GPUs, but all of our developer tooling is on macOS. Anything that can’t run natively in recent Apple hardware gets second-class support.
