We took an M4 MacBook Pro that was already being used by the end user and installed Jamf Pro, which then in turn installed Connect and Protect.

The installation went well. Had the user reboot and user got the message about no network connectivity. We tried a few WiFi connections and an ethernet cable. For the WiFi they are joining the networks but are failing to pull an IP. I verified in our WiFi management there was no DHCP request being sent. Had the user log in locally and they went right to black screens with a curser. A reboot only recreated the problem.

However, once we rebooted into safemode, they had full network connectivity but still ran into a black screen after logging in and authenticating against Entra. I ended up having to pull off all the JAMF product to get the user working again, but the no-network-connectivity outside of safemade still persists.

@FreeGumUnderTheDesks Have you done this successfully before on other Macs?

This was our first in-production domain-to-Jamf conversion. I tested this process ½ a dozen times on both my crash-box mac mini and spare macbooks without issue.

The user was able to spend more time ripping off some remaining Jamf services to get his MacBook back to working as normal without booting into safe mode. I have restaged my mac mini and attempting to recreate the issue so I can work with Jamf support. I did open a ticket and they mentioned the black screen being a known issue but that was a few versions ago.
