I am looking for a way to edit the open with settings in 10.10.1, i have looked through older questions and have attempted to rename the launch services plist and have gotten no where.

I have looked through the


and my


and I was able to remove text edit from random extensions but i am still unable to remove numbers or find its assoisation to .py files in a

/lsregister -dump

Here is a picture to clarify, i would like to remove numbers.app and pages.app along with xcode.app as options to open up files with a .py extension.

enter image description here

Sidenote: Another related feature is i would like to add an application in that menu for every single file type in my system. For example i would like to be able to open every file in my system with hexfiend and textedit.

right clicking/adding every time i have a new file type is a pain because my applications folder is filled with a few apps that are folders that get searched recursively when i look through it

Update: solution directly from apple -- Uninstall numbers. Other then uninstalling the application, it is not possible to remove applications from this list published by apple... any other publisher and it is possible lol.......

  • RCDefaultApp can change defaults, but idk how to remove unwanted apps from the list – Tetsujin Dec 21 '14 at 10:39
  • @Tetsujin sorry initially posted it on stackoverflow then was sent from there to superuser to apple, forgot to delete superuser. RCDefault does look useful but it seems a bit buggy and i can not find where it associated numbers to .py – nsij22 Dec 21 '14 at 10:47
  • No worries, just thought I'd mention it;) Me neither - numbers doesn't show that it ought to be associated with .py, but it is on my machine too. – Tetsujin Dec 21 '14 at 10:49
  • @Tetsujin yeah it is starting to get annoying with so many other file types having 100% useless associations. a different thing that would be slightly helpful would be to say add one application to that list for every single file type on the system, updated question with a sidenote/ explination – nsij22 Dec 21 '14 at 10:54
