(The old version still worked perfectly well if you just ignore STDERR, which is all the modification does for you. When this question was asked the OP did not say that he wanted the number of LOGICAL cores rather than the actual number of cores, so this answer logically (no pun intended) answers with a way to get the actual number of real physical cores, not the number that the OS tries to virtualize through hyperthreading voodoo.ĭue to a weird bug in OS X Yosemite (and possibly newer versions, such as the upcoming El Capitan), I've made a small modification. The latest versions of all Adobe Creative Cloud products are compatible.

Hw.logicalcpu_max: The maximum number of logical processors that could be available this boot. Adobe and Apple have worked closely together to test Adobe Creative Cloud applications for reliability, performance, and user experience when installed on Intel-based systems running Mac OS X Yosemite (version 10.10). Hw.logicalcpu: The number of logical processors available in the current power management mode. Hw.physicalcpu_max: The maximum number of physical processors that could be available this boot.

This number can change when power management modes are changed. Use this number to determine the number threads to create in SMP aware applications. In this video, my successful installation of Mac OS X Yosemite 10.10 on my Intel Core 2 Duo-based PC, and many working hardware devices.Hardware:- 1. Hw.activecpu: The number of processors currently available for executing threads. Use this value for sizing of static per processor arrays i.e. Hw.ncpu: The maximum number of processors that could be available this boot. Interesting values to use in place of "hw.logicalcpu", which counts cores, are (from this comment in the kernel source): Sysctlbyname("hw.logicalcpu", &count, &count_len, NULL, 0) įprintf(stderr,"you have %i cpu cores", count) To do this in C you can use the sysctl(3) family of functions: int count
