This is Mac OS X default behaviour, same as in TextEdit, for example.  
Called soft wrap, I think, ie wrapping on screen but not in the source  
file, as opposed to hard wrap, ie wrapping both in the source file and  
on screen.

But not convenient with TeX, which was conceived with hard wrap in  
mind. If only because isolating an error when only a line number is  
given in the console window may be tricky when the line is very long.  
Not convenient either with FileMerge (from Xcode), when looking for a  
diff in a very long line.

None of this, I think, is possible in TeXShop. There are hidden prefs  
described in TeXShop's help, but I couldn't find any corresponding to  
those settings.

You may have a look at the shareware BBEdit or Alpha, which allow this  
(Alpha having on top a very elaborate TeX menu, and a notion of modes à  
la Emacs). Or install Emacs for Mac: Enhanced Carbon Emacs  
<http://www.inf.unibz.it/~franconi/mac-emacs/> is especially geared  
towards TeX, by incorporating AUCTeX and RefTeX. There are actually a  
number of OS X Emacs out there. Quoting a previous message from 6  
January:

You may also prefer to build Emacs from CVS yourself. Quoting a message  
by Thøger Juul Thorsen from 21 December:

> To build Emacs as a self-contained Carbon app (i.e. completely

Hope this helps,
