PolyBlocker can’t be activated in 4.0 on an M1 Mac

workaround

someone posted a workaround for now:

As a workaround you can fix the code manually.
Go into the addon folder, open line_draw.py

On the first lines (8 and 9) change

SHADER_2D = gpu.shader.from_builtin(“2D_UNIFORM_COLOR”)
SHADER_3D = gpu.shader.from_builtin(“3D_UNIFORM_COLOR”)

for

SHADER_2D = gpu.shader.from_builtin(“UNIFORM_COLOR”)
SHADER_3D = gpu.shader.from_builtin(“UNIFORM_COLOR”)

save it, re open blender and it should work
