see landing page
GPU Driver requirements:
AMD GPUs on Linux require "RadeonOpenCompute (ROCm)" Software Platform (3.1 or later)
AMD GPUs on Windows require "AMD Radeon Adrenalin 2020 Edition" (20.2.2 or later)
Intel CPUs require "OpenCL Runtime for Intel Core and Intel Xeon Processors" (16.1.1 or later)
NVIDIA GPUs require "NVIDIA Driver" (440.64 or later) and "CUDA Toolkit" (9.0 or later)
does your laptop has a discrete gpu or just embedded?
laptops (maybe except for gaming laptops) are not quite suitable for cracking
what do you want to crack/attack?
RE: illegal hardware instructions - VonBaron - 02-17-2022
Its Embedded. Trying to crack doing some try hack me.
It worked on my other laptop running vmware.

intel integrated GPU opencl runtime is broken, you have to stick to CPU only
RE: illegal hardware instructions - VonBaron - 02-20-2022
How do I use CPU then and ger rid of zsh: illegal hardware instruction
RE: illegal hardware instructions - Snoopy - 02-20-2022
add -D1 as option which tells hashcat to use CPU only,
regarding zsh, dont know, try starting hahscat with sudo
RE: illegal hardware instructions - v71221 - 02-21-2022
on Windows it is possible to use Intel GPU with Hashcat v5.1.0 using option -D 2 --force
Please see https://hashcat.net/forum/thread-10548.html
@Snoopy
Please share your opinion why Hashcat v6.2.5 is about 200 times slower than v5.1.0 in my case.
RE: illegal hardware instructions - Snoopy - 02-22-2022
NEVER EVER NEVER use --force unless you are a developer
--force will ignore all warnings and build in safety checks and therefore can or will produce wrong outputs
intel integrated gpu opencl runtime is broken! its like using the orignal hp-35 and wondering why "exp(ln (2.02))=2" easy answer the original hp-35 has a bug
