@goalque, Hello again to these great members.

I have been away for personal reasons during almost one year, but I am trying to giddy again in eGPU stuff.

I used to have a working eGPU set using Goalie great solution (automate-eGPU-EFI-v.1.0.4) in high Sierra with a Sonnet breakaway box 550W and Nvidia GTX1080, in my MBP2016 15" with RP460 dGPU.

but I had to migrate to Catalina and it killed my eGPU installation as expected.

As far as  understand now, the Nvidia drivers are incompatible with Catalina, so I uninstall these. If I am understanding well the post I have read, the most up-to-date solution for Catalina (10.15.7) is goalque EFI v1.0.5.zip set. But in the install post it is said first to check system with 

 ./validate-kexts.sh 

and this returns in my case : Invalid system kext found.

I saw no post about what to do to fix this very first step. My SIP is enabled. Is there a fix to validate kext ?

Thanks in advance if someone knows that.

 

Hi,

I also get the "invalid system kext found" error even after reinstalling Big Sur.

@didierc41 Did you ever find a solution to this issue?  Or if anyone else knows how to fix this, any help would be greatly appreciated.

Thanks.

Hi @olliewhite05, no, I did not find any solution, and got no answer/suggestions from the group.

Maybe I am the only one trying to use goalque's EFI v1.0.5.zip solution with Catalina, and maybe this is not feasible.

Actually since there is - I think - no Nvidia drivers for Catalina or more recent OS X version on Nvidia website, I don't even know wether what I ask for is possible. This may be the reason why I get no answers, perhaps my question is stupid and my quest is vain.

If this is the case please tell me. I will stop trying and sell back my Nvidia GTX1080.

Didier.

@didierc41, GTX 1080 will only work with NVIDIA web drivers on macOS High Sierra. Newer versions of macOS are not supported. You need AMD GPUs for that. Also, it has been pretty clear that NVIDIA (Maxwell/Pascal) support was dropped after High Sierra.

Thank you very much for your answer @mac_editor; it is a pity that the endless war between apple and Nvidia has this effect.

Hence I tried another solution: since before upgrading to Catalina, my HighSierra + EFI v1.0.4 was working with my GTX 1080 eGPU, I tried to rebuild a similar setting using an external drive:

- install a clean MacOS HighSierra on a fast external SSD drive

- Install @Goalque' automate-eGPU-EFI-v.1.0.4 (the version that used to work on my previous setting) choose "hybrid (AMD dGPU)", on a FAT32 USB stick

- run macOS-eGPU.sh to re-install compatible Nvidia driver for this HighSierra version (from  https://github.com/learex/macOS-eGPU)

- boot from this MacOS highSierra, plug the USB stick, option-reboot for EFI boot, log in, hot plug the Nvidia (Sonnet breakaway box)

=> and it WORKS! I ran some Unigine Valley etc bench,  everything was working as fast as before. 

But at my second trial (I mean rebooting etc after a couple of days while), the same booting process results  only in a black screen and system crash 🙁

I tried several steps (plugin the eGPU without login, etc). No way.

Then I uninstall everything (Nvidia web drivers, EFI USB), re-install everything, reboot with the above process: It works again. But just once.

 

I really do not understand what causes this behavior: it seems that the first booting process writes something somewhere, so that any successive trial crashes.

If someone get an idea... I'm desperate.

Didier.

Is there any way to install this locally in the EFI partition? I'm looking to apply a working DSDT that fixes my MBP Late 2012 audio, but I don't want to use a USB all the time.

Is there any reason to use a USB stick instead of a partition on Macbook's internal SSD?

I am interested in this as well, as I just don't want to hang a dongle off the laptop permanently (I have peripherals connected to the Razer Core Chroma itself)

@yui_nishimura, you can remove a USB stick more easily than a EFI partition.

If you have a way to get around booting the EFI partition (hold option key at boot to choose something else, or zap the PRAM), then it shouldn't matter where you put it.

automate-eGPU EFI v1.0.5 Installer

Following content was authored by @mac_editor.

To simplify the installation process, I wrote a little installer that can set up an external drive with automate-eGPU EFI . Note that this installer should be treated as beta. Read all the steps before proceeding:

  1. Physically eject any external drives that you don't want to format. This is to ensure that you or the installer does not accidentally format a drive you care about. This installer does not support SD cards.
  2. Connect the thumb drive you wish to format.
  3. Copy the following into Terminal and press ENTER/RETURN:

    [Please login to see this]

  4. Follow the instructions in the script. If you are on macOS 10.15.1 or newerDO NOT choose AMD as GPU vendor - just choose NVIDIA.
  5. If you are on macOS Catalina, apply the necessary fix.
  6. The disk is now ready to use.

automate-eGPU EFI and this installer are hosted only on this website. If you obtained the EFI installer or files from some other source, we cannot guarantee it's authenticity. You can see the full code for the installer (not the EFI application itself) on Pastebin.

This doesn't work for me. I think the EFI.ZIP source file in your script might be missing.
