People picker not working for safari SharePoint

A few days back we had an issue with the browse window of our People picker in safari browser on MAC.

Issue - Searching and adding a user to the "Add" textbox in the people picker window worked fine but when we clicked on the OK button the window(pop-up) closed itself adding adding nothing in its parent people picker control. The check option however worked fine.

After a great deal of research with Microsoft and comparing files between our development and production environment (since it worked in development and not in production) we found out that one of the javascript files used in _picker.aspx (Its the popup window application page) was core.js and it was not updated as per the updates.

So the conclusion here was that we ran one of the patches in Production (we also did it in development though) which went it with success but didn't update the core.js or somehow broke it which caused the people picker not to work on safari and i think on Firefox as well.

The solution at the end was to either re-run the updates or to manually replace the Core.js in our production environment from our development environment where it was working fine. We adopted the later one and replace the file. Dont forget to do the iisrest after that.


  1. I have the same problem above when using SharePoint on iPad.
    Could you tell me how to fix this please ?

  2. Hi.i have this problem.can you send me your Core.js via Email? (
    here my link but no one can answer it.

    I think problem is in Core,js (in path Program Files\Common Files\Microsoft Shared\Web Server Extensions\14\TEMPLATE\LAYOUTS\INC)
