+**IMPORTANT**: These files are in active development along with the policies in Firefox. To get the policy information that corresponds to a specific release, go to https://github.com/mozilla/policy-templates/releases.
+
+Starting with Firefox 64 and Firefox ESR 60.4, Firefox supports configuration files on macOS.
+
+An example plist file with all options is available here:
+
+https://github.com/mozilla/policy-templates/blob/master/mac/org.mozilla.firefox.plist
+
+If you want to set specific options from the command line, we also provide flattened shortcuts to any item that is nested in the plist file.
+
+For example, this policy:
+```
+{
+ "policies": {
+ "Homepage": {
+ "URL": "http://example.com/"
+ }
+ }
+}
+```
+which would be set in the plist file like this:
+```
+ <key>Homepage</key>
+ <dict>
+ <key>URL</key>
+ <string>http://example.com</string>
+ </dict>
+```
+can be set via the command line like this:
+```
+defaults write org.mozilla.firefox Homepage__URL -string "http://example.com"
+```
+Before any command line policies will work, you need to enable policies like this:
+```
+defaults write org.mozilla.firefox EnterprisePoliciesEnabled -bool TRUE
+```
