The kernel already does this at boot time, and show the results, e.g.: CPU: Intel(R) Core(TM) i7-3770 CPU @ 3.40GHz (3391.68-MHz 686-class CPU) Origin=3D"GenuineIntel" Id=3D0x306a9 Family=3D0x6 Model=3D0x3a = Stepping=3D9 = Features=3D0xfa3fbff<FPU,VME,DE,PSE,TSC,MSR,PAE,MCE,CX8,APIC,SEP,MTRR,PGE,= MCA,CMOV,PAT,PSE36,DTS,MMX,FXSR,SSE,SSE2,SS> = Features2=3D0xffba2203<SSE3,PCLMULQDQ,SSSE3,CX16,PCID,SSE4.1,SSE4.2,x2APIC= ,POPCNT,TSCDLT,AESNI,XSAVE,OSXSAVE,AVX,F16C,RDRAND,HV> AMD Features=3D0x28100000<NX,RDTSCP,LM> AMD Features2=3D0x1<LAHF> Structured Extended Features=3D0x202<TSCADJ,ERMS> TSC: P-state invariant Unfortunately the kernel does not expose this information via any sysctl, so some time after booting it may have "scrolled away" in dmesg. In that case, you can use either the misc/cpuid or the sysutils/cpuid ports to show this information, and even quite a lot more. -Dimitry --Apple-Mail=_E3231C59-6BB4-441A-B802-A6229B55DD7C Content-Transfer-Encoding: 7bit Content-Disposition: attachment; filename=signature.asc Content-Type: application/pgp-signature; name=signature.asc Content-Description: Message signed with OpenPGP -----BEGIN PGP SIGNATURE----- Version: GnuPG/MacGPG2 v2.0.30 iEYEARECAAYFAljOqrcACgkQsF6jCi4glqOw0gCfa41TVzeek6jN0X00//kMk3Wl lLMAnRCr+KwM5hDyaGTW4TzM5hgL+FGd =VnTQ -----END PGP SIGNATURE----- --Apple-Mail=_E3231C59-6BB4-441A-B802-A6229B55DD7C--
