does it work in single-user mode?

[volkere]

the script works fine in multi-user mode. but after my os update to high sierra I realized that my macbook again uses the internal gpu, which led again to the well-known permanent reboot scenario and made it impossible for me to enter multi-user mode. How can I make this script working in single-user mode boot status ?? Would be great if someone can help me out of this trap :-)
