Determine OS

[daChf]

I'm working on a website and need to know whether the user is running Mac OSX or not. How can I do this? Ideally, my code would look something like:

if (using osx) {
  // make slight change
}

Thanks in advance.

You can get the User Agent string and parse it:

string agent = Request.UserAgent;

On my Mac (Firefox 3RC3), it returns:

   Mozilla/5.0 (Macintosh; U; PPC Mac OS X 10.5; en-US; rv:1.9) Gecko/2008061004 Firefox/3.0

On my windows machine (IE 7) it returns:

Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1; .NET CLR 1.1.4322; .NET CLR  2.0.50727; .NET CLR 3.0.04506.30; InfoPath.2; .NET CLR 3.0.04506.648; .NET CLR  3.5.21022)

I think that you can use .Contains("OS X") on the user agent string to see if it is OSX.

That worked. Thanks a lot!
