iMac Pro + eGPU, any suggestions?
@mac_editor Thank you for the reply and the guidance- my bad on mixing solutions, I thought I had read on a post somewhere (whether forums for NVIDIA, Otoy, or here) that they could work together but understood on mixing solutions. I'll go ahead and do a fresh start this evening and will post screenshots of my System Info after doing so.
Last question: would you advise using either automate EFI or purge-wrangler over the other? I believe I thought the interface of purge-wrangler was more intuitive/made more sense to a n00b like myself, but honestly just looking for the best solution. Thank you again for your assistance with this!
You can use what you like and are most comfortable with. Both of them work equally well. Just post screenshots once you apply a solution and we shall try debugging from there.
I went ahead and did some digging on my system- I'm not sure if I was actually able to successfully install 'automate-eGPU' since each time I went to call it and uninstall, it wouldn't respond to the command and when I tried the bash --tunneled command found in the 'Issues' part of the script's GitHub page, it always rebooted but ended with 'The script has failed Nothing has changed'
I currently have the box plugged in, the card seemingly is recognized in some capacity (it lights up and is in report), but still having issues- I've attached multiple screen shots both from the system report as well as the Nvidia managers and finally a screenshot showing some of the packages I've installed. I was/am out of my element so probably installed some conflicting versions/drivers, as you'd mentioned above. Thanks to any and all for assistance, it's much appreciated and I'm a patient, flexible follower of directions!
It’s not clear what solution you’ve used here. Neither of the suggested solutions have a —tunneled command. What are you referring to?
My apologies for being unclear- I firstly ran this: https://github.com/learex/macOS-eGPU, which resulted in an error message 'Your system hasn't yet been approved'. I then found this link on the GitHub page dealing with the issue https://github.com/learex/macOS-eGPU/issues/49, to which Learex replied with a solution which is here: https://egpu.io/forums/mac-setup/script-fr34ks-macos-egpu-sh-one-script-all-solutions-fully-automated/paged/20/#post-46654 OR this command:
bash <(curl -s https://raw.githubusercontent.com/learex/macOS-eGPU/master/macOS-eGPU.sh) --beta --nvidiaDriver 3220.127.116.11.40.105 --iopcieTunneledPatch
Once I used that command it made progress but it ultimately ended with '...Nothing has changed', which made me think that I hadn't installed it after all. I hope that sheds some insight into my process and it allows for some corrective guidance. I have other links to the other methods I tried as well if that's useful. Thank you again for your time and assistance with this, let me know what else I can provide, if anything.
In your system info where it says "Nvidia Chip Model" in Video Card for external GPU... this is where mine will say Nvidia GTX 1070. So your card is not recognized beyond a generic Nvidia Chip Model. I've never bought on the FB marketplace... is the seller reputable? This is a long shot but if your issues persist you could have purchased a bogus card. Do you have a way to test it on another system? Did you find someone with your build (iMac Pro 2017 + 1080 ti) here on the forums yet? You can send PMs if you find someone with your build that may not be following your thread.
Thanks for the comments- understood that it's not being recognized beyond a generic Nvidia chip model. I didn't know the guy I purchased from, but he seemed genuine- will def keep testing in mind as a last-ditch exploration to verify authenticity. Per @mac_editor, I'm going to do a full re-install of OSX, then start fresh with one of the two solutions and report back for (hopeful) guidance and getting on the right path. Thank you all!
Back again. Long story short: wiped disc through Disc Utility, restored from my Time Machine backup (10.13.6), went in and disabled SIP successfully, then went into Startup Security Utility to disable T2 and received "‘Recovery is trying to change system settings. No administrator was found.’ I was able to do this successfully the first time around, baffled why it's not recognizing the User on my machine, it definitely has Admin priv as well.
Do you think this had anything to do w the order that I disabled SIP? Should I have done T2 first?
Finally, I'm open to any solutions or next steps (if you have any) to getting into SSU/around this problem - I haven't found much through searches online, just some secureToken commands. In Recovery Mode I have the option to install High Sierra- could try that, but ultimately would still like to restore from TM eventually- if you think another clean start is needed. Thanks in advance- and always- for any thoughts or guidance!
Try installing High Sierra from recovery on your existing install again (no data will be erased) and see if it fixes the SSU issue. If you had disabled T2 security before already, it should stay disabled.
