My main computer is a mid-2017 MBP fully stocked. I have tons of peripherals, including (2) HD monitors, (minimum of 3 active) HDDs, and plenty more. I am running 10.13.6 Many of my peripherals are attached using a USB hub, and I have no issues. But I also use an OWC USB-C dock and usually whenever my MBP goes to sleep, when I go to wake it everything in the USB-C dock has been ejected. OWC says Thunderbolt 3 is built with a power saving feature that engages when the computer goes to sleep. They also say this is an issue with any Thunderbolt 3 dock and the you will need to manually re-connect the computer whenever this happens. Is this true? I can't imagine everyone with a Thunderbolt 3 drive or monitor has to do this every time your computer goes to sleep. I was told I could disable "sleep" mode but would rather deal with the issue to conserve energy--that is unless it's so little it isn't worth it. My MBP has an SSD so perhaps not much is saved from sleep mode so long as I use a screen saver. Does anyone know? Thanks!
