Chrome on Mac - canvas fingerprint is unique, why?

Hello,

I have some windows PCs and also tested on 2 macs. I'm using the [Canvas Fingerprinting - BrowserLeaks](https://browserleaks.com/canvas) site.

**When I'm on Windows 10 and latest Chrome is says:**

*Uniqueness 99.6% (3598 of 901701 user agents have the same signature)*

**On MacBook M1:**

*Uniqueness 100% (0 of 901701 user agents have the same signature)*

**another old MacBook:**

*Uniqueness 99.99% (1 of 901701 user agents have the same signature)*

​

I've though that Macs should have much less *uniqueness* since …
