mczetah, you are the hero of my day. Thank you, your advised to-do-list solved my problem of my MOTU 828es not showing up as thunderbolt interface in MOTU Discovery on an iMac Pro with 10.14 (Mojave) with a thunderbolt 2 cable and the thunderbolt2/3-adapter by Apple being the only connection.

"Go to Library/Extensions/ and delete all MOTU drivers", new starts and then installation of latest MOTU drivers did the job.

I had a similar problem. Even after deleting the driver I had to reinstall them after every boot. This problem only occurred after I had to restore my Mac from a backup, but anyway…

What worked for me was to exempt Motu kernel extensions from the authorization.

To do this, you have to start your Mac in Recovery Mode (Command + R) and then issue the command:

/usr/sbin/spctl kext-consent add KRCLLMGZ2D

KRCLLMGZ2D is the Motu Team ID as can be seen in About this Mac -> System Report -> Software -> Extensions and there MOTUProAudio (in the Signed-By-Section at the bottom)

From my understanding what it does is that it uses every kernel extension from Motu without user consent which is acceptable for me because I would grant them anyway. But I’m sure there are some which consider this a security risk.

You can revoke it again in recovery mode with

/usr/sbin/spctl kext-consent remove KRCLLMGZ2D

This is very good information... thanks for sharing it.

Unfortunately, comes a bit late for me; I spent more than a day rebuilding my boot drive from scratch after running into the issue you describe... having to reinstall the pro audio driver software to get my Mac to recognize my USB-connected 828es. MOTU was unable to provide me with a workaround. I had gotten lazy, and hadn't gotten around to cloning my DP10.11 boot drive.

The problem got serious for me on a day I booted back into my DP10.11 Mojave boot drive from my DP9.52 Mojave boot drive.

You can bet I now have a clone of my DP10.11 drive. But is is good to know of your workaround. :smash:

A small addition: Also with this kext exemption I described above, the detection of the interface only works when the 828ES is started before the mac or when the mac returns from sleep.
So far, I didn't find another way to detect it, but this works for me for now.
