Using MDS and a Mac Deploy Stick with Jamf

Is it possible for you to post some sort of video or documentation on the process of using MDS and a Mac Deploy Stick to erase and install macOS on a Mac and enroll it into Jamf?

It should be as easy as including the enrollment profile in a folder and selecting that folder under “Profiles” in the Resources section. Was it failing?

First of all, thank you for your reply. To answer your question, “Was it failing?” all I can say is, I cannot truthfully answer that question yet because I am at the ground floor in my understanding as to how this process works in the first place. So I was looking for some tutorials on how to get started. To help you understand how we currently do it, let me give you a brief description.

  1. We first manually erase (wipe the computer) and install macOS onto the computer via a USB flash drive.

  2. We next go through the various installer’s screens and install macOS with a temporary Administrator account.

  3. We next log into that Administrator account and rename the computer to the correct name for our Jamf enrollment process. Next, we launch the Safari web browser and enter the address of our Jamf cloud enrollment server, with the appropriate credentials to enroll and then select the proper Jamf site for the enrolled computer. Jamf then downloads the necessary MDM’s to start the enrollment process.

  4. After which Jamf downloads all of the necessary additional profiles, packages, and scripts based on the site that we enrolled the computer in too. Then Jamf restarts the computer.

  5. Lastly, we login to the computer with its new permanent local Administrator account which Jamf created in the previous step and delete the temporary Administrator user, and check via Jamf for any missing installations or configurations.

So I guess my question to you is, “How do we automate this process with MDS?”

Hi Tim,

Thanks so much for your work on this tool. I’m hoping it’ll save us.

We are in the same boat as the OP: trying to use MDS to erase/install macOS and enroll in Jamf (non-DEP).

At first, I thought I was seeing success via the process you suggested: add Jamf’s enrollmentProfile.mobileconfig (and CACertificate.mobileconfig) into a folder and specify this folder when building the MDS image. Upon the first few tests, everything worked. However, when I try the same image on a second machine, the enrollment fails. I’m wondering if Jamf’s enrollment profiles would be use-limited to a single machine. Of note, I was able to repeatedly enroll the same machine using the same profile with success.

I’m not sure if this is something you can answer, but looking to the Jamf community does not yield any answers, as this method doesn’t seem to be a common practice. Others turn to Jamf’s QuickAdd pkg, but I was under the impression that we should be avoiding this method in favor of using the config profiles for MDM enrollment.

Any input would be enormously appreciated. Thanks again!

Correction: it does seem, via manual testing, that Jamf’s enrollment profile cannot be used more than one time, regardless of computer. It seems that QuickAdd is the only approach, then, but I would love to be enlightened if there is a method of generating a Jamf enrollment profile that CAN be used repeatedly.

Thanks again!

I wanted to report back with my findings, in case it helps anyone else trying to enroll Macs into Jamf using MDS.

  1. The mobileconfig profiles downloaded via https://xyz.jamfcloud.com/enroll/ are single-use profiles that will not enroll more than one computer, so these are not useful when using MDS.

  2. Similarly, the QuickAdd.pkg downloaded via https://xyz.jamfcloud.com/enroll/?type=quickAdd also appears to be single-use and is likewise not useful with MDS.

  3. The QuickAdd.pkg generated using Jamf Recon is multi-use capable and works perfectly with MDS when added as a package to be installed by MDS. No special steps are needed; it just works as you’d expect it to. This is the solution that ultimately worked for us.

Best of luck! :slight_smile:
