Can you take a SIP test?

High Sierra 10.13.2 does not have Active Monitor -> Window -> GPU History.
I can't do a more elaborate test until I install a High Sierra update.

- Macbook Pro 15" Early 2011 with failed AMD GPU - Intel HD 3000 and AMD Radeon HD 6750M
- AKiTiO Thunder 2 Box
- ZOTAC GeForce GTX 1050 Mini - 2GB - Nvidia Pascal
- Thunderbolt 1
- High Sierra 10.13.2 (17C88)

Only used:  purge-wrangler.sh (Version: 6.0.0)

 

Maybe, I said maybe, the problem of SIP enable with eGPU Nvidia is:
Kext Signing is natural to disable (change original kext).
The File System can be tested on rootless.conf. It would not be necessary to completely disable SIP.

Kext Signing: disable

Filesystem Protections: enable


SIP File System config file: 

/System/Library/Sandbox/rootless.conf

Test: OpenGL Extensions Viewer.app show Nvidia eGPU.
Macbook Pro 2011 with Smart TV Samsung -> mirror SAMSUNG -> About this Mac -> Graphics: NVIDIA GeForce GTX 1050 2 GB

Disable SIP partially:

1 - Boot Recovery Mode.

2 - Menu Utilities -> Terminal

csrutil enable --without kext --without fs

reboot now

3 - Boot normal:

csrutil status
System Integrity Protection status: enabled (Custom Configuration).
Configuration:
Apple Internal: disabled
Kext Signing: disabled
Filesystem Protections: disable
Debugging Restrictions: enabled
DTrace Restrictions: enabled
NVRAM Protections: enabled
BaseSystem Verification: enabled

show restricted (SIP FileSystem Enable) and hidden files, directories (ls -O -> Capital O letter)

I am aware that SIP without filesystem and kext protections is sufficient to run patches. However, given how significant these protections are (arguably the largest compromise vectors), and to avoid any complications in the future (I do modify NVRAM in another script, for example), it was easier (for the general user) to recommend completely disabling SIP. You may find this user’s experience interesting: https://github.com/mayankk2308/purge-wrangler/issues/23

Post-patches, it may be possible to keep SIP enabled and rebuild kext cache every boot in the worst case. Do try.

I’ll read through your links once I have some time, thank you. Also, thank you for testing v6.0.0 of the script. While it is not ready for public release, it’s close, so would appreciate it if you find any oddities while using it (including odd/bad console output and the like) and report it in the issues section of the repository.

I read the link you indicated but the user karek314 did not say which version of macOS was installed.

New procedure:

0 - SIP enable and Akitio Thunder 2 Box and Nvidia eGPU GTX 1050 mini always connected to power force and connected to Macbook Pro 2011 (mini Display Port).

1 - I did a fresh / clean install of High Sierra 10.13.6 and then updated SecUpdate 2019-004_july-29-2019 -> High Sierra 10.13.6 (17G8030).

2 - Install Nvidia web driver 387.10.10.10.40.130 -> restart Macbook Pro 2011.

3 - Install CUDA driver 418.163 -> restart Macbook Pro 2011.

4 - Change Info.plist files -> Page 38 - 38 -August 12, 2019 11:13 pm

5 - Rebuild Prelinkedkernel file

sudo kextcache -v 1 -i /
sudo reboot

6 - purge-wrangler.sh (Version: 6.0.0) -> Setup eGPU -> Will you be using an external monitor?  -> NO

7 - Restart Macbook Pro 2011.

8 - Open GL Extension Viewer -> Nvidia GeForce GTX 1050 0 -> Tests
Active Monitor -> Window -> GPU History -> NVIDIA GeForce GTX 1050 -> show blue activity
Samsung Smart TV connected HDMI -> Nvidia GTX 1050
Displays icon menu bar -> Mirror Built-in Display

9 - Restart Macbook Pro.

10 - Enable SIP

csrutil --without kext
reboot

11 - Boot normal -> log in user with Standard permissions -> step 8 -> OK

csrutil status
System Integrity Protection status: enabled (Custom Configuration).
Configuration:
Apple Internal: disabled
Kext Signing: disabled
Filesystem Protections: enabled
Debugging Restrictions: enabled
DTrace Restrictions: enabled
NVRAM Protections: enabled
BaseSystem Verification: enabled

  
System Information -> PCI ->NVIDIA GeForce GTX 1050 -> Tunnel Compatible: No -> GeForceWeb.kext -> no IOPCITunnelCompatible inside Info.plist .

Add:

<key>IOPCITunnelCompatible</key>
<true/>

sudo kextcache -v 1 -i /
sudo reboot

System Information -> PCI ->NVIDIA GeForce GTX 1050 -> Tunnel Compatible: Yes

@nsgr seems the build of the script you were testing wasn't downloading web drivers automatically. If possible, please test again with the latest commit at your convenience. There is now a short document for advanced users on the repo.

@oliverb could you test latest version of the script on High Sierra with NVIDIA? Does clamshell mode work for you (TB3 Mac only)?

Hi @mac_editor, luckily I am still on High Sierra, I will check it after work. Now, it's too risky :p

Already does since v5.1.3. NVIDIA support of course relies on them providing web drivers.

I have not experienced boot hang with the nMP unless the eGPU was connected to Thunderbolt ports other than 5 or 6.

@mac_editor,
finally I could test the new script.
nVidia worked very well and AMD looks good, too.

Thank you!

You are welcome. Clamshell mode works very well, too, but I tested it only with an AMD card.

I like to download the nvidia web drivers and install it manually.

It's great to have this page for the "PurgeWrangler for Advanced Users & Developers" document.
An explanation on the page above about the hexadecimal binary values would be good.
How did you find this value and why did you change it for this other value (patch_binary "${extension_to_patch}" "AB02EF" "BB02EF").
This explanation makes it easy for developers to look at future binary files available from Apple.
Like, these binary files you have to pay attention to and these hexadecimal values you need to look for.

Clamshell mode for AMD GPUs was always functional. The new addition is clamshell for NVIDIA.

I know I have been annoying you in another thread, however I have decided to give purge wrangler a try, however, after I reached the point where it installed AMD legacy drivers, detected the Hawaii/R9 that is in my enclosure, when it reboots, it goes back to the internal Intel HD 4000 graphics. The system does not see my enclosure, or my GPU card. 
Now, I should point out this is not the Vega 56 I have coming, and I am on high Sierra, on a late 2012 Mac mini , however it DID work before, with the automate thumb drive, and not now. 

As you know, the entire reason I am going to purge-wrangler , is to be able to boot with the eGPU active, instead of having to keep one monitor plugged into the Mac Mini . I also did a diagnostic, and all it sees is the Intel Graphics 4000. I looked for hiccups, and all it gave me was Intel HD 4000. 

SIP is disabled. Is there anything I am doing wrong? 

I'm sorry, I forgot to subscribe to the topic, and thought editing this might enable that.

Thanks. Script config looks correct except for Ti82 - which does not need to be enabled - though either way this does not cause problems.

Could you also share screenshot of PCI section in System Report? GPU should show up there in some manner.

Seemingly working great in Catalina (release 19A583). Disabled SIP via recovery, ran the command from GitHub, and it installed fine (sig specs). eGPU appears and worked no problem after reboot.

Thanks for the update! I added Catalina support early on during Beta 2 days. The only tricky bit was read-only system volume which was a quick fix.

On my Mac Mini late 2014 Thunderbolt 2 computer I attempted to run the Purge-Wrangler Script after disabling SIP and got the following error: "curl: no URL specified". Hence, the file did not download onto my mac. This is the script that I downloaded

curl -qLs $(curl -qLs https://bit.ly/2WtIESm | grep '"browser_download_url":' | cut -d'"' -f4) > purge-wrangler.sh; bash purge-wrangler.sh; rm purge-wrangler.sh

Am I suppose to plugin the URL before executing?

Sometimes the command does not work due to high traffic (github API limits). Try downloading the script manually and running it from terminal.

@mac_editor Can you check for possible changes in 10.15.1 Beta that breaks Purge-Wrangler? I ran the patch following system update on my 2013 Mac Pro. Version 6.0.2 didn’t prompt for a reboot so I rebooted manually. Radeon VII eGPU was not working so I ran the script again then fix permissions manually prior to restarting the computer. Half way through fixing permissions the system crashed and corrupted the boot volume. I’m booting into Recovery mode now.

Yes there seems to be changes to how Apple checks thunderbolt compatibility, which should render my patch ineffective. Henceforth I advise any macOS users on Thunderbolt 1 and 2 to avoid macOS 10.15.1 until I find a new patch. I will require your assistance in testing them since I do not have a TB2 Mac. It may be possible that @goalque's patch still works. You can try that patch manually and report back for now.

@mac_editor Absolutely. Recovery mode to fix my boot volume was successfully. I ran the patch again manually (w/o plugging in eGPU) and there’s no difference. System Status within your script reports correctly that TB1/2 AMD eGPUs was Disabled.

I think I already found what to patch. Just investigating. Will send you an updated script once I have investigated a little more and updated the script with the needed changes. However, things may change over betas so we don't know how its going to end up.
