I get the same results with a Portuguese keyboard layout. This, of  
course, like another poster has said, has to do with the fact that  
when you press ^ it is considered as a diacritical that may be placed  
upon the next letter -
to produce ê, or â, for example. I am not sure what one can do to  
remedy this (my personal choice is to use an "international", or "us"  
keyboard layout, even though some keys become out of place; it works  
for me because I know where everything is, but this is not for  

Barring using a different or modified layout, the only option might  
be to deal with it in TeXShop's autocompletion. You can't redefine  
the "dead-key" behavior in this way - i.e., you cannot expect to  
press the normal ^ key and not get the yellow box, etc, but if you  
can get by just pressing the space bar after ^, here's a simple  
  The autocompletions are defined in ~/Library/TeXShop/Keyboard/ 
Open this file in a text editor (I use Smultron; you might be able to  
use TextEdit - but make sure the file is saved as plain text, not rtf).
Look for the following lines:

(they should be near the start of the file). In the second of these  
lines, remove the ^ character to get

Now you can press ^ followed by space to get ^{} with the cursor  
inside the braces. Not ideal, but I believe it's the best one can do  
without changing the keyboard layout.
