Any reason you're not using TeXShop 2.26?

MacTeX/TeX Live 2009 is in the testing phase so there are bound to be  
glitches. It's actually too bad that this list has been informed about  
it without a warning.

I'd wait until MacTeX 2009 is actually released before updating. I'm  
sure you'll hear about that here.

Some of the changes, e.g., to the graphics system, are a bit  
disrupting but they are getting fixed quite rapidly. As I said MacTeX/ 
TeX Live 2009 is still in the testing stage.

When you update with MacTeX both your original 2008 and 2009  
distributions will coexist. You change the active distribution via the  
TeX Distributions System Preference Pane. That way any time you run  
into a problem you can always change back to your known stable  

The bad thing about this is that each distribution takes up ~1.3GB so  
you've got to have the disk space available to them to coexist.

Finally, if you have files in the texmf-local branch and/or your  
personal tree they will be used with whichever distribution it active.

Hope this helps.
