GTX-550Ti gIOScreenLockState Loop

[David811]

Hey,

Earlier I followed the guide to install MacOS Sierra. Everything works fine, since I added 1023 as VRam and injected NVidia (but I dont used NVIDIA WEB drivers).
Now I wanted to upgrade to HighSierra. I installed it with the same options from Sierra. But after that I got a bootloop
The last line said: "IOConsoleUsers: gIOScreenLockState 3, hs 0, bs 0, now 0, sm 0x0".
The OS boots with the bootflag "nv_disable=1"
In here I found my graphics card :"https://www.tonymacx86.com/threads/graphics-testing-benchmarking-chart.177227/"
--> So I installed today the new "NVIDIA Alternate Graphics Drivers" for HighSierra 10.13.5
For this I followed this post: "https://www.tonymacx86.com/threads/new-method-for-enabling-nvidia-web-drivers-in-clover.202341/"
Can anyone help me out?
At the Attached Files are my working Sierra plist and my HighSierra plist.
Greetings David

any luck with your 550 ti? i have the evga. Once in the desktop i go to about mac and it all works. Internet, sound, but with 1200x800 resolution. Under graphics the card is listed properly. Even gives a rom revision number under the system report. But no acceleration. Lags heavily to do anything. Drivers are installed. Web & cuda. But not working. Thinking of cheap 10 dollar radeon card on craigslist, no one really uses this on a high sierra build. no info on getting to work even if its possible. Anyhow best of luck to ya!

I remember someone saying that old Nvidia graphics cards like your 550 Ti may have problems in High Sierra. They work in Sierra and older versions with "Inject Nvidia" in Clover.

I suggest upgrading your graphics card if you really want to use High Sierra. Otherwise stay with Sierra.

Posting it on craigslist as we speak. Have spent hours with all sorts of kext. I’m just going to get a hd 6870 on craigslist and call it a day. Unless I learn how to edit hex files I’m going to stick to my skill level. Lmao. Thinking of writing tutorials for the rigs I got up and running. All thanks to everyone on this site!
