I installed uDig 1.1.M8 on my home computer (running OS X version 
10.4.5) earlier this week. Some information that might be helpful 
for other OS X users:
1. Java Advanced Imaging is automatically installed with 10.4. Users 
still using 10.3 can download and install JAI from 
http://www.apple.com/downloads/macosx/apple/java3dandjavaadvancedimagingupdate.html 
(reference: http://developer.apple.com/java/faq/apis.html#anchor1)
But uDig requires Java 5/1.5 which can only be installed on Tiger.  
Manually installing it on Panther is unsupported and may not 
completely work.
2. Image I/O is NOT automatically installed, and needs to be 
manually installed to support some of uDig's functions (I found this 
out when trying to load a world file for the first time). There is 
no specific OS X version of Image I/O, but jai_imageio.jar from the 
Windows or Linux installers 
(http://java.sun.com/products/java-media/jai/downloads/download-iio-1_0_01.html) 
can be used by placing the jar in 
/System/Library/Frameworks/JavaVM.framework/Versions/1.5/Home/lib/ext 
before running uDig.
(reference: http://docs.codehaus.org/display/GEOT/2.2+Dependencies)
Instead of putting extensions in the System, where they may get 
trashed by system updates, put them in /Library/Java/Extensions, or 
your home, ~/Library/Java/Extensions.  Java is supposed to look in 
these places for user extensions.
