XnView 1.70 - Outdated
For Mac OS X, there is XnView 1.70 for Mac OS X, availabe. Please note that compared to XnView on Windows this XnView version is outdated (compared to the XnView on Windows) and 'speaks' English, only. Also the look of Motif is different to other Mac OSX applications.
Installation of XnView 1.70
Xnview Software
XnView 1.70 requires X11 (Motif). By default, X11 is not installed on Mac OS X, so you have to install it. When searching apple.com for X11 you will find many hits. From what I can see this is the Apple page for X11. On that webpage it says: '- Bundled: Optional install from the third Mac OS X v10.3 Panther CD.', so you might have it already on your installation CDs. Otherwise you have to download the package (43MB) - download link is on that page.
XnView MP

It may still be worth like having a look at the test version: XnView MP - Early development version
So all in all the current situation with XnView on Mac OSX is not good (with XnView 1.70), but looks promising (with XnView MP).
