Ventura 13.5 on an Apple M2 Pro for me :
my experience this weekend on a live gig with the Motu 828 MK3 Hybrid is similar , the beach balling yes , I have a few more artifacts like the focus of channels 1-8 avail but nothing higher than that , I have a MOTU 8 Pre as a converter breakout for another 8 analog XLR mic pre into the 828 mk3 . Also using touch OSC as a client , and the focus of channels seems super flaky glitching hard on the touch OSC device .
I have used this system successfully with an older Big Sur MBP 2017, even incorporating a Mackie MCU as a control surface added and "cabled" in Audio MIDI Setup, that seems not doable on my Apple M2 Pro MBP Ventura 13.5. Can add the Mackie device but cables won't take , really can't get off the ground with MIDI connected to the Motu 828Mk3 Hybrid with the Mackie MCU , which does work great on an older Mac OS . Also the work around downgrading to Monterey isn't possible on this M2 Pro Ventura , can't blow off my hard drive to work around this issues with this particular device it's managed by work through Kandji sadly , woe is me lol . I can't have my Kandji and it eat too .
Touch OSC does work however , there is this issue , for me particularly :

This demonstrates the 10 second lag on adjusting Main Out and Mix Bus output master faders and mutes , ten second lag !
The response of the channel and eQ faders etc is fine and real time , however the mix bus master and mutes give it ten seconds , that is crazy long and you can't work like that in a live situation I have found out the hard way unfortunately .
I'll go back to the MBP 2017 , why didn't I foresee those challenges , learn the hard way , that's the way it is for me sadly .
edit: indeed the MBP 2017 intel machine on Big Sur runs CueMix perfectly with no issues , M1 M2 Silicon etc , doesn't work flawlessly , but it works do a degree , the master busses fade and mutes 10 second lag , and the glitchy Focus of channels on Touch OSC is a major concern . Stick with the older OS and and older machines for CueMix on the 828 MK3 Hybrid for Touch OSC implementation
