Hashcat 3.0 CL_UNKNOWN_ERROR

[trebla]

I get the same error on a pretty old laptop with an unsupported GPU. But I want to run CPU-only without OpenCL, is that possible with hashcat?

Code:

clGetDeviceIDs(): CL_DEVICE_NOT_FOUND

It works with my other computers that has OpenCL capable GPU, but not on the laptop with crappy GPU. Is CPU-only support dropped?
