Panchroma Muted White is the one that is somewhat similar to the Apple platinum color. Someone sent Polymaker an RGB color code instead of a sample, so it's pretty off in reality. That would be fine, because all machines are yellowed to some degree anyway, so colors vary widely. More importantly, it's just terrible filament. Layer adhesion is virtually non-existent, compared to Polymaker's Poly Lite filaments. I have wasted so much time trying to print that awful filament. Hopefully this manufacturer is better.
I've not had too many issues with it on my crappy Ender 3 clone. I print at 225C with a 60C bed, which lowers to 55 after the first layer. Never had any problems other than typical bullshit with my Z-offset.
I don't have bed adhesion issues. The prints are just extremely fragile, features peeling off at the slightest provocation. The filament binds to itself a little bit better (but still not great) if I print at 230° with a cooling profile that tops out at a max 20% fan speed, but one can't print details or overhangs in those conditions.
And since I didn't actually see a link to the filament in the Ars Technica article, here it is https://polarfilament.com/products/retro-platinum-pla-1kg-1-...
