Hi all, Does anyone have familiarity with Metal 2 on Mac? We are working on a 3D rendering tool on Mac and are having major issues testing on older Macbooks using Metal's
Performance Shaders (Macbook Pros Mid 2012 and 2015 running macOS 10.15) and newer MacBook Airs using Metal's Performance Shaders (Macbook Airs early 2015 running macOS 10.15). When testing rendering using examples from Apple or derived from Apple examples, the screens appear red on older MacBook Pros and black on Mac Book Airs. We have no issues testing on later model Macbooks or on iPads. We would appreciate any guidance to help us resolve this. It has held us up for months in testing with no resolution yet. Thanks so much and Happy New Year!

With knowing more we don't know what could be going wrong. Sometimes something that works on one device but another points to a GPU driver bug, but there are also some thing that you need to do differently depending on the device.

Are there particular GPUs are you seeing these problems on? MacBook Pros can have both and Intel and an AMD or nVidia GPU. The MacBook Airs all have just an Intel GPU.

Can you describe what your app is trying to do with Metal when you run into problems?
