XnView Software

Hi, I am thinking about using XnViewMP for my work Mac. I know it's only free for private or educational use, but I cannot find any payment/pricing info on the website for XnViewMP. The only thing I can find is the payment for XnView Windows version (I use a Mac...) and a "Donation" for XnViewMP. Can you provide more info on this, e.g. pricing and how to pay? I need that to convince my manager for the purchase. Thank you!

The license for XnViewMP is the same as XnView, so by purchasing a license of XnView, you can use XnView or XnViewMP
