Most likely you had set "xetex" as your TeX personal script, and 
"xelatex" as LaTeX personal script, in Preferences/Script. This is 
perfectly right, and part of a successful XeTeX install. But...

Then the above error message indicates that you were running XeLaTeX 
without knowing it (Mr Jourdain ?), most likely because you had set 
"Personal Script" as your default script, in Preferences/Typeset. 
Hence, every time you press LaTeX, XeLaTeX is run, and every time you 
press TeX, XeTeX is run. In other terms, because Personal Script was 
your default script, XeTeX had become your default TeX.

Cure: just set pdfTeX or TeX + Ghostscript as personal script. You may 
then erase or not xetex and xelatex as your personal scripts.

Quite normal: erasing your whole TeXShop/teTeX install just because of 
that problem was overkill. The TeXShop prefs are actually stored in 
~/Library/Preferences/TeXShop.plist. For example, mine has:

	<key>TexScriptCommand</key>
	<string>xetex</string>
	<key>LatexScriptCommand</key>
	<string>xelatex</string>

and Personal Script as the default script corresponds to:

	<key>DefaultScript</key>
	<integer>102</integer>

Hope this helps,
