I find this sdk for mac osx with buildin webcam
Software:
The barcode scanner project, written in Cocoa, is for scanning barcodes on books, DVDs, CDs and video games as well as most other kind of EAN or UPC barcodes. It is part of our programs - DVDpedia, Bookpedia, CDpedia and Gamepedia - and is also used by Books. The code is available for free in the hopes that it'll be useful to other Mac developers. Of course it would be great if it were also improved with other developers' expertise and knowledge.

All of the scanners from Intelliscanner (intelliscanner.com) work well with OS X as does the POS-X XI3000 (which seems to have been replaced by the XI3200 (http://www.pos-x.com/product-XI3200-31.aspx), which I have not used).
Note, when plugging one of these in sometimes the "Can't determine your keyboard…" window opens up. If that happens, just click the red dot to close the window as you should not need to (nor can you) use the keyboard setup to make them work.

Most USB scanners are simply keyboard emulators. If OSX can take a standard USB keyboard then I'd imagine that it can take a standard USB barcode scanner such as the ones that Symbol do.
