Installing LaTeX on iMac For years I have been a LaTeX user on Ubuntu. I want to know how to install/use LaTeX on Mac.

I generally use it to write mathematically intensive documents and make slides (on beamer). In future I am likely to use a lot of photographs on my slides. 

I would be glad if someone can tell me what is the good way to install LaTeX on Mac. (..and also how to run it..) I am comfortable compiling it from some terminal. 

I was looking at MacTeX, is that good (or the only one!?)

I was wondering if that comes bundled with a text editor too optimized for LaTeX. If not then kindly suggest me a good editor too. I am used to GEdit on Ubuntu. 

For editor I was looking at TeXShop.

So will I have to install both TeXShop and MacTeX ?
TeXShop is already included in MacTex (also LaTeXiT, which is probably more interesting for you). Basically, MacTex is a carefree package, which should include everything you would ever need in a  LaTex distribution. This really is the best way to install LaTex on a Mac, it's easy and requires little to no configuration (basically what you get used to on a Mac).

If you just want a text editor and run all the LaTeX command in Terminal, you can use TextWrangler, which is free and very good. It's not LaTex specific though and doesn't do any LaTex highlighting. If you want that, you may want to look at Aquamacs Emacs, which does very good highlighting.
