for exemple some member on OSX or Linux telle me not seeing item Autolinked 
That’s interesting - I’ve tested Autolink thoroughly on a number of browsers including Linux browsers and it works fine. All the processing is done on the server side so what is delivered to the browser is standard HTML markup. Aside from IE’s lack of support for the <abbr> tag (which was addressed in the last Autolink release), I’m not aware of any other issues (I can’t vouch for OSX as I’m still saving to buy a Mac)
IMHO, there is more risk with using JS-based solutions as there is the possibility of visitors to the site having javascript disabled. But, as long as unobtrusive javascript solutions are utilised then it shouldn’t be a problem.
