Hi guys! This should be a no brainer, but I am having troubles. I downloaded the 2011 version of MacTex. It comes with TexWorks and TexShop. When I double click on .tex files, they open by default in TexWorks, but I want them to open by default in TexShop. It should be a simple matter of right clicking on a .tex file, using 'open with' TexShop, and checking the box that says 'always open this type with ...' But that is not working. It seems to be ignoring the fact that I checked the box Anyone else have this issue? EDIT: It doesn't actually ignore it. It ignores it for all other .tex files except for the one I right click on. I want the default to apply to ALL .tex files.
