my main goal is to make my OS look like another.
For Example I use Trisquel OS which is based upon Ubuntu, but I'd rather disguise myself as looking like Linux Mint, or Mac OS.

Correct, that's why I've changed the "user agent string" on every browser, to an OS that's obviously different to what I'm using.

However, do note that you need to be part of the "majority", and not "minority". For Instance, It serves very little purpose If you select an OS that's only used (for example) by 500 users globally. It's a lot easier to track & Identify 1 In 500  than  1 In 10 million.
