Short description of error
The error with the hair particle system involves the clumping editor. In Blender versions of Windows and Linux,the hair particles are clean and behave like Example #1. However,for Mac OS,it's a whole different story. Instead of the slider behaving like it should,it makes the hair clump incorrectly like in Example #2. This really bothers me and I think it should be fixed.
