You have to specify a font that includes the letter µ, at the  
appropriate Unicode slot. This isn't the case of the default TeX  
fonts (i.e. the Computer Modern fonts). You need to use an AAT (the  
OS X font technology) font instead, or an OpenType font. For example,  
Hoefler Text.

Try downloading the xunicode and fontspec packages from:


Then install them inside ~/Library/texmf/tex/xelatex/, and compile  
the following (the first two lines are for TeXShop, in case you're  
using it):

     %!TEX TS-program = xelatex
     %!TEX encoding = UTF-8 Unicode
     \setromanfont[Mapping=tex-tex]{Hoefler Text}
      This is the greek letter µ. (yes, this is $\mu$).

Works here (you'll notice the difference between the two µ's, the one  
from Hoefler Text and the other from Computer Modern.
