To check if CPU supports HugePages 1GB size, look out for presence of flag pdpe1gb in /proc/cpuinfo. Here we’re asking for hardware and machine information:- $ sysctl -a hw machdep.cpu What we do have on MacOS is the sysctl command, which will show us similar information (though in a less compact form). ![]() However, lscpu is not supported on MacOS (at least not to the depth of my Google-fu) that is hardly surprising, since it is effectively a summary of /proc/cpuinfo which is a Linux invention.
