hi, so just a few days ago my new macbook finally arrived, and i am getting used to using OS X as my primary OS for the first time in years. anyway, i am looking for a file difference viewer for mac os x, similar to winmerge, which is fanTASTIC, by the way. http://winmerge.org/ the idea is to view two text files side by side, and the differences between the two are highlighted, and you can edit one file or the other. any ideas? i guess this is most useful to a programmer, though not necessarily.
