Manage Google Chrome

[malonso]

I am trying to manage Google Chrome browser the last post on this that I have been able to find is from March 2014. Can anyone point me to any direction were I can commence this. Thank you

Manage it how? Enable Auto Updates without needing an admin password, disabling updates completely, restricting certain settings?

If you are wanting auto updates without an admin prompt, we have been using this script without issues

#!/usr/bin/env python
# encoding: utf-8
"""
chrome-enable-autoupdates.py

This script enables system wide automatic updates for Google Chrome.
It should work for Chrome versions 18 and later. No configuration needed
as this is originally intended as a munki postinstall script.

Thank and sorry for the vague details. We are looking into adding a startup url and some standard bookmark tabs and remove ability to change download location.

[patgmac]

Take a look at https://github.com/ProfileCreator/ProfileCreator

Quite a bit of Chrome settings available in there.

@malonso

Haven't done this in a very long time so please correct me if I'm wrong &/or missing a step - hope this helps

I believe by adding these lines to the users com.apple.launchservices.secure.plist (Located -> '/Users/$USERNAME/Library/Preferences/com.apple.LaunchServices/com.apple.launchservices.secure.plist ') chrome will be the default application called when opening the following prefix for urls

    <key>LSHandlerRoleAll</key>
                <string>-</string>
            </dict>
            <key>LSHandlerRoleAll</key>
            <string>com.google.Chrome</string>
            <key>LSHandlerURLScheme</key>
            <string>http</string>
        </dict>
        <dict>
            <key>LSHandlerPreferredVersions</key>
            <dict>
                <key>LSHandlerRoleAll</key>
                <string>-</string>
            </dict>
            <key>LSHandlerRoleAll</key>
            <string>com.google.Chrome</string>
            <key>LSHandlerURLScheme</key>
            <string>https</string>
        </dict>
        <dict>
            <key>LSHandlerPreferredVersions</key>
            <dict>
                <key>LSHandlerRoleAll</key>
                <string>-</string>
            </dict>
            <key>LSHandlerRoleAll</key>
            <string>com.google.Chrome</string>
            <key>LSHandlerURLScheme</key>
            <string>ftp</string>
        </dict>
        <dict>
            <key>LSHandlerContentType</key>
            <string>public.html</string>
            <key>LSHandlerPreferredVersions</key>
            <dict>
                <key>LSHandlerRoleAll</key>
                <string>-</string>
            </dict>
            <key>LSHandlerRoleAll</key>
            <string>com.google.Chrome</string>
        </dict>

& then deploying a plist (i did it with a config profile -> "Custom Settings" with the plist passed as is displayed in secure plist above ie "com.google.Chrome" - you want to save the plist displayed BELOW as "com.google.chrome.plist" before uploading it.

Image Example Below - "Upload_Field_Custom_Settings_Filename" is where you upload the plist.

You can upload the following plist & config it how you see fit,

<?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>DefaultBrowserSettingEnabled</key>
    <false/>
    <key>HomepageIsNewTabPage</key>
    <false/>
    <key>HomepageLocation</key>
    <string>www.Website Homepage.com</string>
    <key>RestoreOnStartupURLs</key>
    <array>
        <string>www.Website 1.com</string>
        <string>www.Website 2.com</string>
        <string>www.Website 3.com</string>
    </array>
    <key>RestoreOnStartup</key>
    <integer>4</integer>
    <key>ShowHomeButton</key>
    <true/>
    <key>IncognitoModeAvailability</key>
    <integer>1</integer>
</dict>
</plist>

i dont manage chrome anymore, but this is almost everything you need. i dont know the key for setting default download location for the plist but hopefully this helps.

[malonso]

@Hugonaut will test and report

[sdagley]

@mlizbeth Be aware that the chrome-enable-autoupdates.py script has been updated to handle changes to the keystone framework path introduced in Chrome v75. It's not shown in the History section of the script, but the keystone_registration_framework_path() definition has changed.

[CorpIT_eB]

@malonso There is also the BASH variation that works very well as well, and was recently tweaked for the changes made by Google with the release of v75.
