Hi Juan Manuel

My guess is that you have the TexShop preference "Auto Compleltion" 
turned on. This setting will directly replace a certain typed character 
with a sequence of replacement characters. Which characters are being 
replaced and what they are replaced with is given in the 
autocompletion.plist file that you can find in 
~Library/Texshop/Keyboard/autocompletion.plist (mine seems to work fine 
- maybe yours has gotten corrupted somewhere along the way).

For your problem you can either
    a) turn off autocompletion and rely on the latin1 inputenc to 
correctly typeset ä,ö,ü, etc.
    b) keep autocompletion on and edit the autocompletion.plist file to 
correct the replacement of  ä,ö,ü with \"a, etc. and add other matches 
that directly give you \"i for example.

Hope this helps.
