eGPU Razer Core X, MacbookPro, AMD Radeon RX580

[dakrulski]

Hey,

I tried to use an AMD Radeon RX580 with Razer Core X as an eGPU on my MacBook with hashcat and it doesn't work.

My OS Version is Monterey 12.5.1

I tried to use the homebrew hashcat version and I compiled a fresh hashcat with:

Code:

git clone https://github.com/hashcat/hashcat.git
mkdir -p hashcat/deps
git clone https://github.com/KhronosGroup/OpenCL-Headers.git hashcat/deps/OpenCL
cd hashcat/ && make install

I can not get it to work  

Code:

./hashcat --version
v6.2.6-216-g5adb38430

Code:

./hashcat -I
hashcat (v6.2.6-216-g5adb38430) starting in backend information 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.

Is there a way to solve these issues?
I read that OpenCL can not be upgraded on Mac, so I think I'm stuck with the 1.2 version  Is there a way to make it work with 1.2 in hashcat? Maybe an older version?


I hope somebody can help me.

If you can upgrade your system to macOS Ventura (13.1), then hashcat will work with Apple Metal. If not, I recommend you use an older version of hashcat available at the bottom of hashcat.net. Personnally, I like v3.6.0 and it works great on macOS with OpenCL 1.2.

If you need to crack the latest and greatest hashes and you don't need macOS, then I recommend installing Linux on your system. I currently run Ubuntu 20.04.5 LTS on my 2014 Macbook Air and it works great with the latest version of hashcat.
