Anyone encountered crash when disconnecting eGPU on big sur?  

11.2.1 and I'm still encountering crashes whenever I try to disconnect via the menu option or just unplug it.

For me it's the unreliable sleep mode that is most irritating. Half the time the computer crashes when it wakes up. Safely disconnecting the egpu in Big Sur seems to be impossible too.

@alexosaurus, sleep is no longer an issue when using kryptonite. Disconnecting still is and need to be done via hard unplugging the thunderbolt cable or powering down the eGPU  box. 

@netcho, but unplugging the cable causes the system to crash or to freeze. It seems that for me the only way to safely disconnect a egpu right now is to shut the computer down and disconnect the cable. Or just to let the computer crash. 

@alexosaurus, this is strange that it crashes. You have very similar sister setup to mine. Have you tried to close all the apps and then unplug the cable? Does this also produce a system crash?

Same here. It's made me barely use my eGPU(s) because I know that session is going to end up with a nasty crash.

However, I do have a better experience with the RX 580 eGPU where ejecting seems to still work on Big Sur (11.4) but the VEGA based WX 9100 eGPU will absolutely NOT safe-eject ever. Actually yanking the cable has a higher chance of not crashing than the eject function.

I've been filling bug reports with Apple since the Big Sur betas for this and they've not taken a blind bit of notice.

I tried the WX 9100 on macOS 12 beta and it's the same. Safe eject eGPU freezes the MBP.

I'm tired of it and seriously considering selling my eGPUs and waiting / hoping the M1X/M2 chips will have GPUs with at least VEGA64 levels of performance. I know that's not enough performance for everyone but it would be fine enough for me if it was not crashy.

I used to have system crashes during sleep or eGPU eject in macOS. The culprit I found was Adobe CC service. I disabled it from login items and my macOS system has been running very predictable. Look through your background services and see which one tends to complain when you eject the eGPU.

@itsage, I haven't got Adobe CC installed on the macOS 12 system and the VEGA class eGPU still hangs / crashes on eject. Pulling the cable then revives macOS 12 but you cannot use an eGPU again until restart.

Does quitting the Adobe CC Desktop app solve it on Big Sur? Or is it a specific Adobe process that needs killing first?

@gelert42, I was using Adobe CC as an example of a third party application that has conflict with eGPU eject/surprised removal. Your scenario may be different so it takes some investigation to find what is the culprit.

Mine also crashes often. Sometimes Kernal Panics and restarts. Sometimes it just hangs until I unplug the cable and then it comes back to life. It's almost always a "widget" that is causing it to not disconnect- like screen time widget or something like that (it's not always the same one).
