Oops, I did forget to mention that didnt I?

Shell escape is a mechanism which basically stops TeX processing, allows an external program (like epstopd script) to run and then resume the processing. The problem is that it allows any program to be run. So if someone sends you a malicious TeX file, it can do good amount of damage like wipe your home folder.

It is not default setting in TeX. So if you run TeX/LaTeX/pdfLaTeX from command line you have to explicitly tell it something like shell-escape etc. Iti s however default setting in TeXShop. Check the TeX run script in TeXShop. It is also mentioned in TeXShop Help.

It has the potential of creating a lot of damage. I have never heard of a malicious TeX file. So *practically* the risk is minimal. But you have een warned. Use shell-escape only on files from trusted sources.
