Today managed to hook up my brand new MacBook Pro running Mojave to my beloved Midas Venice F32. USBC to Thunderbolt 2 adapter daisy chained to a Thunderbolt 2 to FW800 adapter. Turned off SIP in Terminal, installed the last Midas driver, turned SIP back on and finally allowed TC system extension in Privacy settings. Works! I was convinced to wouldn’t but it does. Don’t give up on your Midas FW mixers.
