EuControl & Mac Studio

[imixit]

Just set up new Mac Studio ULTRA. Having the same problem.

EuControl sees the surfaces, but Pro Tools doesn’t (neither does Logic.) 3 X S1, +Dock & 4 tablets. Haven’t changed network config from my previous (working) Mac Mini Intel. (Meaning I unplugged my Ethernet network setup from the Mini and plugged that into the Mac Studio. Not feeling network is the issue as Eucontrol sees the surfaces (NO Application in ASSIGN tab with Pro Tools running.)

Mac Studio M1 ULTRA

Monterey 12.3.1
Pro Tools 2021.20.12.
(EUCON IS SWITCHED ON AND I HAVE TOGGLED/REBOOTED ETC>)
EuControl 2021.10.1.29 (EuCon 4.8.3.29

My brother received his a couple of weeks ago and his (single) S1 is working. The only difference is he is running 12.3.0 and I did the (Apple) recommended 12.3.1 upgrade on install… could this be it? (AVID are you listening???) Can I roll back to 12.3.0 without starting over? (Erase, reinstall, re-migrate)?

Otherwise Pro Tools running smoothly (albeit 4 unhappy plug ins: Stratus 3D, VisLM, Slapper, Lexicon PCM (ancient))

I need surfaces working… help!
