You can get detailed information on CPUID on the web, including sample code and tutorials. Primarily all APIs use this instruction to retrieve CPU information. It gives all possible information of a CPU including its family, model, company, number of cores etc. sysctl vm.swapusage VM stats - see man sysctl for other options, or just try -a and look through the whole list. Replace -u with -orsize to sort by resident memory size instead. If you specifically want CPU information then use cpuid (in C asm cpuid) instruction. Shows processes sorted by CPU usage, updated every 5 seconds (I find the default of 1 second to be too fast), as well as load average, physical & VM stats, etc. How can I find out how many processors the Mac OS X box Im currently logged in has The command sysctl hw.ncpu will help you out. The temperature can probably still be read from the SMC, but it looks like the keys changed for the M1, and might even be different. You can get frequencies and power usage for CPU and GPU with powermetrics, but not the temperature, as far as I can tell. The Motorola 68020 was the first 32-bit Mac processor, first used on the Macintosh II.The 68020 had many improvements over the 68000, including an instruction cache, and was the first Mac processor to support a memory management unit, the Motorola 68851. The SMC sampler is not available on the M1 (or on Big Sur, not sure which). Here's how to quickly find your Mac's CPU model via Terminal. To get even more information on your Mac’s CPU, click System Report. This is fine for most users, but those troubleshooting issues or hoping to compare their Mac to a PC or older Mac may want to know exactly which CPU is powering their system. When buying a new Mac, Apple provides basic CPU info but hides the specific processor model. On Linux there is mpstat and /proc/cpuinfo, both of them don't seem to exist on Mac OS X server. Sometimes I need to gather information about the client's server prior to making real work there, i.e.
