What are the possible repurcussions of unplugging an eGPU without ‘ejecting’ it?












0















So, at least on macOS, your computer may complain when you simply unplug a Thunderbolt / PCIe GPU:



macOS error message when eGPU unplugged: GPU not disconnected properly



I've basically been ignoring this, so far — when my computer is asleep, it takes a substantial time for it to wake up, and all my displays to turn on and become responsive. When it's time to leave the house, I don't really want to sit down at the computer, wake it up, attach my smartcard, log in, and select ‘eject eGPU.’



So: What downsides are there, to simply unplugging a PCIe (via Thunderbolt) GPU from a laptop? Especially any specific to Macs?

  • I'm pretty sure GPU drivers run in kernel space, so I imagine a kernel panic (full system crash requiring reboot) is a possibility.

  • Hardware-wise you should be safe as the port is hot pluggable, but you should always follow the proper procedure
