A tool to help users with pre-existing devices enroll into MDM

UMAD (macadmin's Slack #umad)

[U]niversal [M]DM [A]pproval [D]ialog

Embedded Python

As of v2.0, UMAD now uses its own embedded python (currently v3.8). This is due to Apple's upcoming removal of Python2.

FoundationPlist has been replaced by Python 3's version of plistlib

Nibbler has been updated to support python 3.

Building embedded python framework

To reduce the size of the git repository, you must create your own Python. To do this, simply run the ./build_python_framework script within the repository.

This process was tested on Catalina only.

./build_python_framework

Notes

You will need to use munki-pkg to build this package.

Because of the way git works, umad will not contain the Logs folder required for the postinstall to complete. In order to create a properly working package, you will need to run the following command: munkipkg --sync /path/to/cloned_repo/mdm/umad

OS Support v1

The following operating system and versions have been tested.

• 10.10.0 Note 1, 10.10.5 - Note 2
• 10.11.0, 10.11.6
• 10.12.0, 10.12.6 (10.12 is very unreliable with DEP nagging)
• 10.13.0 10.13.3, 10.13.6
• 10.14.0
• 10.15

OS Support v2 (embedded python)

The following operating system and versions have been tested with the embedded python.

• 10.14
• 10.15

Getting started

To start, you can use the default settings in /Library/LaunchAgent/com.anothertoolappleshouldhaveprovided.umad.plist

Essentially every component of the UI is customizable, using the above LaunchAgent.

• Create your .pkg with munki-pkg and install on your target workstation.
• Open terminal. example

/Library/Application Support/umad/Resources/umad --cutoffdate 2018-9-7-17:00 sets the cutoff date to September 7th at 5pm

Cutoff date

Cut off date in UTC.

<string>--cutoffdate</string>
<string>2018-12-31-17:00</string>

Cut off date warning

This is the number, in days, of when to start the initial UI warning. When this set of days passes, the user will be required to hit an "I Understand" button, followed by the "Close" button to exit out of the UI.

<string>--cutoffdatewarning</string>
<string>14</string>

Due date text

This is the bolded portion of the UI towards the top under the "titletext".

<string>--duedatetext</string>
<string>MDM Enrollment is required by 12/31/2018 (No Restart Required)</string>

DEP failure text

If a user has a DEP capable device, but they are past the enrollment window, they will have an option to manually enroll.

This is the first set of text above the enrollment button.

Enable enrollment button

Always show the manual enrollment button, DEP or not.

<string>--enableenrollmentbutton</string>

Honor DND settings

If a device is DEP capable, umad will not honor DoNotDisturb settings so the nag can actually appear.

If the admin wants to honor DoNotDisturb for DEP devices, use this feature.

Non-DEP devices will honor the users DND settings

<string>--honordndsettings</string>

Logo path

You can replace the included company_logo.png with your own company_logo.png or you can configure a custom Path with the following string:

<string>--logopath</string>
<string>/Some/Custom/Path/company_logo.png</string>

Manual enrollment text

If a user does not have a DEP capable device, they will have the option to manually enroll. Authentication may be required for manual enrollment.

This is the bolded text that takes place of the DEP or UAMDM screenshot.

<string>--manualenrollmenttext</string>
<string>Manual Enrollment Required</string>

Manual enrollment h1 text

If a user does not have a DEP capable device, they will have the option to manually enroll. Authentication may be required for manual enrollment.

This is the first set of text above the enrollment button.

<string>--manualenrollh1text</string>
<string>Want this box to go away?</string>

Manual enrollment h2 text

<string>--moreinfourl</string>
<string>https://google.com</string>

Nag screenshot path

You can modify the LaunchAgent adding your custom path or just replace the included nag_ss.png with your own .png. (remember to name the file nag_ss.png if you are not using a custom path)

<string>--nagsspath</string>
<string>/Some/Custom/Path/nag_ss.png</string>

Profile identifier

This is the profile identifier for < 10.13 machines to check for enrollment. Should you not set this value, umad will attempt to look for a profile installed on the machine with the PayloadType of com.apple.mdm

<string>--profileidentifier</string>
<string>B68ABF1E-70E2-43B0-8300-AE65F9AFA330</string>

To get this value, run the following command on a computer with your MDM profile installed: profiles -C -o stdout-xml

Look for the MDM profile and notate the identifier. Some MDMs may use a UUID for this value.

Some examples:

<dict>
	<key>ProfileDescription</key>
	<string>MDM profile</string>
	<key>ProfileDisplayName</key>
	<string>MDM Profile</string>
	<key>ProfileIdentifier</key>

Tips, Tricks, and Troubleshooting

• I made changes to the default LaunchAgent and now the UI isn't appearing?

  Make sure you unload, and reload the LaunchAgent after making changes.

• Where is the logging located?

  /Library/Application Support/umad/umad.log

• Why isn't the log file there?

  Remember to unload and reload the LaunchAgent.
