Same high sierra version, no work.

According email to me from Sonnet Support from today:

'....We have one of those Macs in the lab. When we tested under 10.13.1, it tested OK. We went back and retested under 10.13.2 and it doesn’t work for us either.
Do you have a time machine backup that you can use to go back to 10.13.1?
Your case has us concerned. We have temporarily pulled our compatibility information for all non-Thunderbolt 3 Macs until we can understand better what 10.13.2 did to Thunderbolt 2 Macs...'

Be careful 10.13.2 and TB2 MacBooks does not work right now 🙁

I just send Apple feedback. Maybe they won't answer, but at least they will know there is a problem or a suggestion for change. If enough people send feedback, it may get the problem/suggested change solved sooner.

Sent feedback.  Better to send now, early and often, than wait to get screwed over.  I'd encourage anybody concerned to do the same.

Based on current trends, in my opinion Apple is going to kill eGPU for TB2 Macs as a way to reduce complexity and support issues, and more importantly to them, as a way to ensure they maximize profits on their new Thunderbolt 3 lineup of Macs (now and going into 2018). No doubt there are people in a decision-making capacity there who see offering support for TB2 as a potential money-losing policy, especially with owners of the 2013 Mac Pro and similar era laptops. They want all those people upgrading. If the #1 reason many of them would upgrade is to get the performance benefit of more modern GPUs, the eGPU offers a cheaper alternative — with less than $100 going into Apple's coffers (i.e. only the Adapter since they won't sell GPUs or eGPUs outside of the dev kits, which are underpowered for most purposes).

Really a bad deal if it happens for 2013 Mac Pro owners given how frustrating an experience it has been for those requiring good GPU performance, but I will not be surprised at all. Better to count on Apple killing TB2 for eGPU and being pleasantly surprised if they don't, than the other way around.

Bring peace to your computing life: stop trying to understand Apple.

Not only they are going to kill TB2 Mac but also on the others TB3 Mac using some GPU hungry app like Final Cut Pro X (new just released 10.4 version has eGPU disabled on both TB2/TB3 Mac). Maybe Apple was forced to go eGPU but is something that they do not like because they do not sell GPU nor eGPU (as just said by Chippy McChipset) and could represent a threat for new Macs.

Actually TB2 was never planned to be compatible with eGPU for Macs. That's what I remember from the keynote when they announced eGPU support. However if eGPUs will work on tb3 Macs, probably some bright minds will find ways how to enable them also on TB2 machines.

Yeah, it makes perfect sense. The eGFX certification only applies to Thunderbolt 3 enclosures, so *officially*, even from Intel (aka, outside of Apple), only Thunderbolt 3 setups can be eGFX supported. TB2 was always a "well, if it works, then have fun with it, but don't look at us if it breaks" type of thing.

Just got another TB2 to TB3 Adaptor (pricey things as well) so I could use my Mid 2015 MBP on the eGPU until they iron out the driver issues. I've installed the Public Beta of 10.13.3 today and I got one go with the eGPU that did work (fast render, really good) and I thought that's great - this'll be fab now but then it crashed hard and it's taken me several bad restarts with nothing attached to get the laptop back up at all.

There were graphic artefacts all over the place.

It's still borked. As soon as you load Safari the whole Mac bogs down. It won't quit anything. Graphic artefacts happening. It's completely screwed.

How does Windows 10 fare on a 2015 MBP with the eGPU? Does it work? I'll buy a copy of Windows 10 if it'll work with the eGPU. I can dropbox my files over to render on it. Don't mind doing that.
