Bug Why is Cura single-threaded on Mac?

[GAD 9]

I have a 24-core Mac Pro and watching Cura slice complex models painfully slowly while one CPU gets pegged at 100% is maddening. 

 

Why is Cura single-threaded?

The brand new Cura 5.1 version has now multi threading support also for MacOS.

 

- Implemented multi-threaded slicing for MacOS, to bring it in line with other operating systems.

The reason for that was that Apple, in all it's wisdom, decided not to adhere to standards for a long time. THey have since done that, so that's why we can now support multi threading without having to do double the work.

I am not surprised one bit.

I look forward to 5.2 because 5.1 just quits on me with complex slicing. At least there's hope! 

 

Thanks all!
