nvidia webdriver w/High Sierra problem

@h9826790 @bsbeamer after trying the power cycling, it didn't work still...

I tried the 970 and 1080Ti again on my PC and it booted up fine with the display showing on the same 2 monitors I have so I am really not sure what's causing it to not work. It is possible that 10.13.4 broke the NVIDIA driver for some of the cards...
 
If you’re positive this isn’t a driver install issue, you could roll back your NVIDIA driver with a script. There’s info on that in another thread.

How are you powering the cards in your PC vs Mac? Trying same exact cables and monitor(s)?

Both GTX 970 and GTX 1080 Ti boots into desktop with it not displaying anything. If I were to only use 1 card only slot 1, either the GTX 970 or GTX 1080 Ti, when I screen share to it, the Nvidia web driver would not see either of the cards properly.

It does look like software issue. But don't know what's wrong.

If there is anything in system preference -> security, "allow" it.

If nothing there, my next suggestion is to try completely disable BOTH Gatekeeper and SIP.
 
@bsbeamer @h9826790 I just re-installed my Mac with 10.13.3 last night and will try out the v387 Nvidia driver...

@bsbeamer On my PC, I am powering the 970 directly from my PSU, 2 6-pins but Mac Pro requires the mini 6-pins to regular 6-pins from the motherboard so it won't be apple to apple. I am using the same dual monitor to test.

@h9826790 I checked system preference -> security and there weren't anything to "allow" except when install the Nvidia driver, but I am going to try disabling Gatekeeper and SIP, just need to look up how now...

Thanks for helping out, really appreciate it!!

For 10.13.3, I recommend you run the following command in terminal to install the V378 driver (ONLY do this AFTER SIP DISABLED)
Code: 
bash <(curl -s https://raw.githubusercontent.com/Benjamin-Dobell/nvidia-update/master/nvidia-update.sh)

IMO, this driver works better (less bug) and the 10.13.3 V387 driver.

@h9826790 I just tried the script with a fresh install of 10.13.3 (17D47), it installed the driver version of 378.10.10.10.25.106. I pop the 970 in and tried to boot, no boot chime nor any display shows... I am starting to feel either the Zotac 970 PCB is different from reference or my power cable isn't delivering enough power to my card...

Possible, my personal choice is also stick to the reference PCB is possible.
 
As mentioned before, I've had numerous issues with Zotac cards in the past. They are (usually) heavily modified from reference designs and not (usually) compatible with the NVIDIA driver. Stick with cards from NVIDIA directly or cards that keep/have the NVIDIA logo on the board (near the PCIe connection) vs. cards with the company/manufacturer logo there. Cards without the NVIDIA logo are modified from reference in some fashion and can cause more headaches than it's worth.
 
Just an update... I recently tested my gtx 970 on my windows PC and it actually had screen glitches and turned black after a while. It seems something I did while installing and removing 970 caused it to fry... it is also possible my bridge pci-e connector has blew my card...
 
@h9826790 just an update about the bridge cable and using 8 pin to 2 6+2 pin cable... The cables I purchased were
https://www.ebay.ca/itm/16AWG-Dual-...e=STRK:MEBIDX:IT&_trksid=p2057872.m2749.l2649 and https://www.ebay.ca/itm/PCI-e-8pin-...e=STRK:MEBIDX:IT&_trksid=p2057872.m2749.l2649

I found these 2 products on Amazon

https://www.amazon.ca/gp/product/B0768RRRGC/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1

https://www.amazon.ca/Express-Mothe...coding=UTF8&psc=1&refRID=TTCVCHEHH12MC9W286DF

In the description of the first Amazon product... it says it is a CPU connector cable so I am wondering if this was the reason it "fried" my 970 and causing it to not boot up properly on the Mac Pro?
