Repro steps:

1. Import the attached package to a VFX-enabled project on Win
2. Observe how the colors are organized.
3. Repeat for OSX
4. Observe how the particle color is assigned randomly with the same settings.

Expected outcome: the OSX behavior to match the Win behavior

Note:
- I've tried baking a new pCache in OSX, but the results are the same, so the issue might be with the actual Set Color from Map block.
- The original mesh is also included in the package.
