Hi!



We're just starting with Jamf and we wanted to set a company webpage as a homepage in Safari. I read a little about it, found code for custom profile and wanted to have a go.



The code I found is this (replaced the site name with facebook):



<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">

<plist version="1.0">

<dict>

    <key>HomePage</key>

    <string>https://www.facebook.com</string>

    <key>NewWindowBehavior</key>

    <integer>0</integer>

</dict>

</plist>


When I try to upload it, I get a message "Unable to create object from file". Weird thing is, last week I tried to make a configuration file to enable TeamViewer (the same extension and stuff) and it works perfectly, each time I'd try to do it.



What may be wrong with the file?

When I get the "Unable to create object from file" error.. it's usually because a profile already in Jamf has the same name or same uuid.

I would try creating a Safari profile using ProfileCreator, and then uploading a custom mobileconfig vs pasting in the plist data under the custom profile payload in Jamf.



@gachowski How exactly should I cope with this? I've change the name, what about uuid?

@kjubus
Be sure both the UUID and name are different from any other profiles in the jss. We had a conflict recently and tracked it down to a duplicate profile name, even though the uuid was different. I’d always assumed that jamf only used the uuid, but no. Once i changed both items, it uploaded successfully.

Usually when I edit the profile in Xcode the uuid is there and I just change the last number...but I am starting to think you might not have a uuid...



Did you try with the ProfileCreator? That is what most everyone uses...



C

Silly question, but did you use defaults to write the plist or did you type it manually and save as a plist?



Can you try the following with any success?



Note: com.domain.plist should be replaced with com.apple.Safari.plist (if Safari are the preferences you are trying to manage)



#!/bin/bash

/usr/bin/defaults write ~/Desktop/com.domain.plist HomePage -string https://www.facebook.com

/usr/bin/defaults write ~/Desktop/com.domain.plist NewWindowBehavior -bool FALSE

/usr/bin/plutil -convert xml1 ~/Desktop/com.domain.plist

I was editing an existing mobileconfig file with ProfileCreator and tried to upload that to replace the older revision of it when I got that error. I was able to resolve my issue by running uuidgen and replacing the existing UUID with the one that was generated. it uploaded just fine after that.

@AVmcclint Did you change the UUID using ProfileCreator? I don't see a way to do it in the application.

I just ran the uuidgen command in Terminal. It’s been so long since I did it, I don’t know what the actual process is, but I think it just generates a new UUID and you copy/paste that into JSS.

Just used uuidgen on a crowdstrike config profile that 2 different uuid's in it, and was apparently preventing upload.  Worked great.
