TexShop looks lovely.

On there site there is also an equation editing utility, which is quite handy for really long and complicated equations with lots of special symbols and brackets. On XP TeXade made equation. Tex this is a beauty!

\begin{equation}

- {1 \over {N\sigma (\nu )}} \left( {\ell {\partial \over {\partial x}} + m{\partial \over {\partial y}} + n{\partial \over {\partial z}}} \right)I_\nu (x,y,z;\ell ,m,n) = I_\nu (x,y,z;\ell ,m,n) - \frac{B(\nu ,\mu ,T)}{4\pi}

\end{equation}

Bonus points for knowing what it does!

Do you know of a MacOS version of LaTable, the table formatting utility?
