Set Microsoft Edge as Default Browser

[adl-gavinator]

Hi All,

I need to find a way to set MacOS to use Microsoft Edge as the default browser.  Either by script or config profile.  Alot of auth/token services do not work with Safari on Monterey so would like to avoid using it altogether.  

We would also like to give users the option to move to a MacOS device and a good attraction is the ability to sign into Edge (which they used on their Windows machines) and have their favourites, browsing history and cookies appear on the MacOS version of Edge. 

Any help would be greatly appreciated. 

Gavin

Hello Gavin,

This may be useful for setting Edge as the default browser: https://github.com/targendaz2/Mac-Set-Default-Apps

Hi @Rocketman_Zac unfortunately this script does not work for python3.  It is written in python2 I believe.

@adl-gavinator Great catch. Thanks for the heads up!

What variables am I changing here to target Edge @dmccluskey ?

[MMTechno]

I have got massive problems with that.. I can run this ok from self service and all is working fine!

I have then tried to incorporate it into my build process and i call this as a policy with a trigger from my install script. I know for a fact that the user is logged in. I have actually added a "cat" command  into the policy so it echoes the contents of the .plist file and i can see that all the values populate. However after my workflow's reboot the plist is empty. Any ideas? I am on Sonoma and we are on Jamf 11.4.1

^^^ Please disregard this - i found the issue - basically i have been applying the script during my workflow and the settings seem to be overwritten by Company Portal's settings but just momentarily - Added the script to run after the company portal has exited and all is good! 

[dmccluskey]

you also need to reboot too

[adl-gavinator]

Mine shows this.  Your parameter 4 and 5 have titles...

[dmccluskey]

thats because need to customize those fields in the script options if you want fancy names.

[adl-gavinator]

Thanks for your help!  This worked like a charm.  I may try and work a reboot into my deployment somewhere as a next step.
