Verovatno misliš na Get Info dijalog i Open with: opciju. Kod Open with: si verovatno primetio da se aktivira Change All... Poenta je da fajl osim ekstenzije ima i svog kreatora, program koji ga je napravio.
Sad, ti programi se indentifikuju po ključu od četiri slova i moguće je da kada odradiš Change All... da si promenio otvaranje za tu ekstenziju ali ne i taj creator code. Primer za ovo ti je "običan" jpg i jpg koji si napravio u Photoshopu. Sa pdf-ovima ti je još očiglednije, tu se svaki ispočetka otvara u drugom programu.
Rešenje: budi uporan sa Change All... opcijom. U najgorem slučaju ćeš morati da je primeniš par puta iako je po pravilu dovoljno jednom.

Most operating systems use file extensions (endings) to distinguish files from each other. For example, if a file ends with “.psd” it’s usually a Photoshop file, or if it ends with “.txt” it’s usually a text file. But Mac OS X also allows files to be marked with 4-digit Type and Creator codes. These Type and Creator codes override the file extensions. For example, you can mark a file with the code “8BIM” and then Mac OS X will know it’s a Photoshop file, even if it doesn’t have a “.psd” ending.
iLikeYouMore allows you to easily change the Type and Creator codes of any file. You can also use iLikeYouMore to erase these Type and Creator codes, which can be useful for applications like BBEdit, which adds its Creator code to any files it can get its hands on, even if your default application for those files is something else.
