Compiling LaTeX in Apple products: is something like pdflatex around? My Apple friends says that they cannot compile LaTeX. I don't have a Mac at hand to test what the problem is. 


How can I get something like pdflatex to get LaTeX compiled on a Mac such as a MacBook or iMac? 
What about iPad? How can I compile LaTeX on an iPad?


I suggested my friends to compile things on their servers and use Sshfs, more here, but they have problems getting MacPorts. I am now trying to find some local way of doing things.
Have them download http://www.tug.org/mactex/. It contains all they need to edit (via TeXShop) and typeset (via a complete LaTeX distribution) LaTeX documents.

For the iPad, have a look at http://itunes.apple.com/de/app/tex-touch/id377627321?mt=8 and http://itunes.apple.com/us/app/tex-equation/id390366359?mt=8.
