Just testing out a simple starter app using the sample code included in the README. Unwrapping the result of Window::new_centered panics with the error SuitableContextNotFound.

I did also experiment with building a window without vsync, but the results were the same.

Sorry to hear that, I'll look into this.

Out of interest, what kind of Mac are you using, and which type of GPU?

Also if you have the full log please (including the bit where it's trying different multisampling levels) that would be very helpful.

I'm running: iMac (Retina 4K, 21.5-inch, Late 2015)
The GPU is: Intel Iris Pro Graphics 6200 1536 MB

I've rerun the demo code from the examples directory and got this log:

Thanks!

It looks like the issue was that macOS was unhappy with us explicitly requesting a Core context for GL 2.0: a0a3513

I've published v1.0.4, please let me know if that fixes the issue for you. The fix works for me on a (cloud rented 😄) Mac Mini, so I'll mark this as resolved.
