I just got a Macbook and I'm attempting to build a chess engine, so I want to run the perft function on Stockfish to compare my perft results. When I was on PC, I was able to download the engine from the website and run the perft function fine, but I can't figure out how to do it on mac. I tried downloading Stockfish with Homebrew which apparently worked but when I tried the ./stockfish command to run t it outputted this error: zsh: no such file or directory: ./stockfish. Can anyone provide complete steps to do this? Or if there's any alternative that has a feature equivalent to what Stockfish's perft does that would be good too.

  • what is the executable called? this question is more suited for unix or apple stack exchange.

    @qwr I wasn't sure where to post this but I decided to put it here because I figured that more people would know how to solve this in case it was a Stockfish-related problem and not purely a Unix problem. The executable in the src folder is called stockfish if that's what you're asking. I tried opening Stockfish by clicking on the executable icon and I got a zsh: illegal hardware instruction error in the terminal window that opened

  • which MacBook are you using? You need to get a binary that matches your hardware. If it's designed for M1 chip then you need to get that binary version.

    @qwr I'm on a 2023 14 inch pro with an m2 chip. So do I need a different version of Stockfish?

    you installed through homebrew? that means it should be in your PATH right? what happens if you try stockfish without ./

Solution: I downloaded stockfish through homebrew and was able to run it on the terminal with the command stockfish. All other commands are the same.
