Hello!
I have the site fundemic.com and I need that my customers that use mac by opening my site would go to one page and that use windows to other, or that description of category would change depending on the os version. My pages are categories and created dynamically by k2.

I have this code <?php echo $this->category->description; ?> in categories.php
And I need to call category by it's number and show description of specific category if my customer is using mac. And I want it only in case that customer just enters to my site, because there is button that transfers to "mac" and "windows" page and i want that this button would continue work properly.

Please help me.
