UGH T2 Chip nightmare - Anyone using FOG with T2 macs
-
Sometimes deploying an image works, like if it is the same mac and it is the same install the image was captured from but if I wipe the drive and deploy the image I get the dreaded No Administrator account found. What is the trick? Definitely not a FOG issue but thought someone here might now.
I don’t like these newer macs at ALL. The T2 chip is foolish.
-
@Fog_Newb Maybe post a picture of the error.

Are you using the one off bzImage-T2 kernel or the current kernel that is 5.15.x series?
-
@george1421 Oh that is right. I forgot about putting the T2 kernel on the new FOG server. Shoot. Where do I get the T2 Kernel again and does it go on the FOS stick or the FOG server?

@fog_newb Here is a one off T2 kernel I created in Feb 22 (did’t remember I did this). I don’t know if its been tested yet.
https://drive.google.com/file/d/1de5-9hZbqaGO_PTG8wWm5mz_m60BG9lx/view?usp=share_linkHere is the older one that is known to work https://drive.google.com/file/d/12St-Wix1io0s0oXhgxAuLlQOVoT9548L/view?usp=share_link
The question where it goes depends on how you boot the device. PXE boot it goes in /var/www/html/fog/service/ipxe directory on the fog server. If you boot from usb drive then it goes into the /boot directory on the usb drive. Adjust the name to match the older kernel name.

@sebastian-roth The mac, the image is deployed then it boots to the mac OS login screen, it displays the only account on mac OS when the image was captured. But it doesn’t accept the password. It tells me if I can not log in - reboot into Recovery. Recovery doesn’t allow me to make any changes because there isn’t an Administrator account associated with the installed OS (Not to be confused with activation lock) The image was captured from the same mac it was deployed to.
I would be happy to provide pics but to do that I would have to duplicate the problem which means the mac will be down.
Apparently this is a thing with T2 macs when imaging. The admin account gets stripped of its admin rights amongst other things. A quick search brought me here
Unfortunately deleting ‘.AppleSetupDone‘ and rebooting did not restart the set up. It just brought me back to the login screen which displayed my admin account (at least it was an admin account when I captured the image) but wouldn’t accept the password.

@george1421 I boot from a FOS usb stick that pxe boots to the FOG server. So I am thinking put the T2 Kernel on the server and specify that kernel under the “host kernel” setting for the macs, then on the the FOS stick put the t2 kernel as well?
-
@george1421 What does the T2 kernel do differently than the stock kernel?
-
@fog_newb The T2 kernel is built with patches to enable the T2 chip that is not part of the main linux kernel distro. I was kind of hoping that the patches had been accepted by now to the main kernel so having a one off kernel wasn’t necessary. FOG uses the main linux kernel source code (kernel.org) and then compiles it specifically with just the needed bits for high performance imaging. That makes it small and very fast OS.

No Administrator account found
Some more google foo revealed this piece of information: https://apple.stackexchange.com/a/379170 (done before capturing I suppose)
Unfortunately deleting ‘.AppleSetupDone‘ and rebooting did not restart the set up.
Did you mount and delete the correct filesystem/file? https://apple.stackexchange.com/questions/164331/i-dont-have-administrator-account-on-my-mac#comment587819_164332

@george1421 Cool. Is the T2 Kernel known to address this specific issue?
