I tried installing the latest Web driver, but no luck.

Please find the details below:

These are my system specs from OS X El Capitan

Please help

Thank you

Huh ?

Define the problem.
Boot in verbose mode and post a picture of the screen when it stops.

Sorry, my bad.

I tried the following:
1. Web Driver
-In the login screen, mouse was retaining its path as I move around
-Somehow, I managed to log in, Resolution 1080p, but highly unresponsive and flickering screen
-You can see blocks on the top left of the screen, and windows are transparent and flickering

2. Verbose + Web Driver
-Did not stop anywhere
-Rest same as point 1

3. nv_disable=1
-Booted successfully with low resolution and no graphics acceleration

Thanks

Remove Little Snitch.
Attach your config.plist.

Your config.plist is corrupt which is the same as having no config at all :

config.plist: Close tag on line 1088 does not match open tag dict

Hi I fixed the config file and tried again, no luck

Would I be able to fix the problem If I swap the graphics card with a newer one?
Which graphics card would you recommend for High Sierra? Preferably 2GB-4GB
Thanks
