System Information
Mac OS Sierra 10.12.6 with Intel HD Graphics 6000

Blender Version
Broken: 2.79b f4dc9f9

Short description of error
The error with the hair particle system involves the clumping editor. In Blender versions of Windows,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.

Are you sure you are examining the same files in Windows/Linux compared to MacOS?

Because when I open provided file on Linux, I get the same result as posted in picture #2.

The reason for some of the child particles appearing shorter than the parent particles is the Length ("length of child paths")

This was set to 0.8 in your file, and the threshold of 0.1 was causing 10% of the children being full length, the remaining 90% were only 0.8times as long as the parent particles.

If I set the Length back to 1.0 I get a result as posted in picture #1.

Is that what you meant?

Marking as incomplete for the time being...

Oh,my God! I just realized that I made a mistake. I replaced the top screenshot with the correct one and I corrected the versions of Blender. Sorry for the inconvenience.
