The new Macbook Pro with the Radeon Pro 460 (if not other GPUs) has support for OpenCL 2.2, which will make OpenCL much easier to write, compared to earlier versions. Why isn't there support for OpenCL 2.2 in OS X, and when can we expect to get it?
Not having it is a real issue for me, and feels like Apple is trying to force its own proprietary approach onto its customers -- something sure to drive people away. It's already a problem for my productivity; the "Pro" line shouldn't have issues like this.
