Excellent add-on, but it seems to be optimized only for Windows users. When tested on a new Mac mini Pro M4 (the most powerful one), Blender 4.3 becomes very laggy.
Your question comes from Blender's poor support for Mac, especially GPU, because the development of this add-on was done on Mac M2, and Composer cannot support Mac, especially GPU, very well. This is what Blender should do So this evaluation It makes me feel very uncomfortable
Colorista is an amazing addon and a blast to use! It adds a vibrant, stylized look to scenes with ease, and it’s really fun experimenting with the color effects. The viewport performance is great—everything looks exactly as expected while working in the layout or shading tabs.
However, I’ve run into a recurring issue when it comes time to render. While the effect displays fine in the viewport, the final output often renders as a completely black screen during the compositing phase. This seems to happen inconsistently, but when it does, it breaks the final composite and has even caused Blender to crash a few times. It’s made rendering unpredictable, which is a shame because the addon itself is so well-designed and enjoyable.
Would it be possible to get an update for Blender 4.4? And if there’s any way to troubleshoot or fix the black screen issue during final render, that would be fantastic.
Really hoping to see this addon get more love—it’s got a ton of potential!
