Macos run error.

[mlinton]

I am attempting to run hashcat compiled and run on Macos Monterey with GPU acceleration, and it is throwing an error regarding some kernel file not existing. I first attempted an install with homebrew which didn't work, and then this is from the latest github version.

OS information (a macos VM in qemu):

hashcat (v6.2.5-108-ge18d16bc6) starting in benchmark mode

Benchmarking uses hand-optimized kernel code by default.
You can use it in your cracking session by setting the -O option.
Note: Using optimized kernel code limits the maximum supported password length.
To disable the optimized kernel code in benchmark mode, use the -w option.

@mlinton please use the binary from the github cloned folder, without using "make install", only "make"

This can be simply fixed by running:
mkdir -p ~/.cache/hashcat/kernels/

You'll note the error message is complaining about that directory not existing. This creates it.

Hi, I think the problem in this case is another. I would try with -D 1 to understand in the meantime if it works by selecting the CPU. He will most likely also have to create the directories as you indicate :)

@mlinton free to re-open this issue if you want to share more details
