Need help with Mac + Metal - azuha - 11-28-2025
Hey everyone. First timer here. Well, and a little bit of a noob.
I've a Macbook Pro with the base M4 chip.
MacOS: 15.7.1
hashcat: 7.1.2 installed.
No matter what I did, I couldn't make the hashcat work with Metal. Asked various AI's, couldn't get anywhere.
It always skips device 1(metal) and reverts to device 2(OpenCL).
Hashcat recognises both GPU variants(Metal & OpenCL).
hashcat -I :
% hashcat -I
hashcat (v7.1.2) starting in backend information mode
Metal Info:

Even with -D 1 command, it still skips it.
Did I miss something ? Or, am I doing something wrong ?
Oh and, -O command doesn't work either.
When I run the hashcat with the "-O -D 1" commands, this is the output:
hashcat (v7.1.2) starting
Kernel /opt/homebrew/Cellar/hashcat/7.1.2/share/hashcat/OpenCL/m22000-optimized.cl:
Optimized kernel requested, but not available or not required
Falling back to pure kernel
No devices found/left.
I'd be glad if you fellas can help me out.
Thanks in advance...
