You say that because of sticking with High Sierra for now? I get where you're coming from, but I don't upgrade my real macs to the newest os for studio use either. I have multiple engineers and several rooms that need to open projects/sessions from any other room. Any sorts of changes can be a big pain in my ass...I'll do it at some point here, I'll just need all my regulars to bring in all their hardware USB toys so we can test it all out. The problem I was just having was USB working for some midi devices and not others (looks like the truncated ports kext has fixed that).
As for the install, I did spend the whole day following the KGP guide (from post install + TSCadjust from pre), implemented all the relevant SSDT's other than I disable wifi, bt and built in audio in bios.
I am using
SSDT-X299-TB3HP-APR.aml because I found a post from KGP that even though it shows up in PCI as GC-Titan Ridge Thunderbolt 3 NHI, it's still the best one to use for the TBEX3 card as well. Is there a better one to use?
The TB card not showing up after a hard crash or power-loss isn't actually new to me. It's how it has always worked which is why I tested it. I was hoping that might be fixed, but no biggie if not.
Thanks for all the help!
