After fresh-boot mac Pro Tools can’t reach HDX driver within 5-7 minutes after the start of the macOS.
Problem has appeared since 2018.1 in January on High Sierra 10.13.3
Each time I reboot the Mac, if I want to launch Pro Tools immediately I should launch and quit Pro Tools 3 times minimum.
if after a computer boot it took 5 minutes or more, everything starts fine.
SIP is OFF. “spctl” is “—master-disable”.
Mac Pro 6.1 with Thunderbolt 2 Sonnet expansion
