Well Kemper Family,
i think ink this was the culprit to all my latest problems. I'm not 100% sure, but process of elimination has led to this unit.
1) it's the central hub that all my broke audio units were plugged to
2) my 2nd monitor was constantly going black like it thought it wasn't online
3) ISB sticks stopped reading like my iLok
4) my latest audio unit the Apollo Twin stopped being seen over Thunderbolt
5) the iMac would reboot every 24 hours from an unrecoverable fault. Since removing the dock it's not done that
6) when rebooting the iMac would get a white screen for a loooong time
