    Both of my macs reported in "machdep.cpu.features" only AVX1.0. I executed this command

      sysctl - a | grep avx

    On one mac (blur disabled) I got

      hw.optional.avx1_0: 1
      hw.optional.avx2_0: 0

     

    On another mac (blur enabled) I got

      hw.optional.avx1_0: 1
      hw.optional.avx2_0: 1

While I would have preferred to not have to run a terminal command to figure this out, I believe I know why this isn't working.

 

My Macbook Pro does not support AVX 2.0.

 

sysctl -a | grep machdep.cpu.features

machdep.cpu.features: FPU VME DE PSE TSC MSR PAE MCE CX8 APIC SEP MTRR PGE MCA CMOV PAT PSE36 CLFSH DS ACPI MMX FXSR SSE SSE2 SS HTT TM PBE SSE3 PCLMULQDQ DTES64 MON DSCPL VMX EST TM2 SSSE3 CX16 TPR PDCM SSE4.1 SSE4.2 x2APIC POPCNT AES PCID XSAVE OSXSAVE TSCTMR AVX1.0 RDRAND F16C

 

Let me know if you think this is not the case.

doug4772 I got the same result on my MacBook Pro (i5 2018) too. Odd, as AVX2 dates back several years. Turns out there's another command to show extended instruction sets:

sysctl -a | grep machdep.cpu.leaf7_features
machdep.cpu.leaf7_features: RDWRFSGS TSC_THREAD_OFFSET SGX BMI1 AVX2 SMEP BMI2 ERMS INVPCID FPU_CSDS MPX RDSEED ADX SMAP CLFSOPT IPT MDCLEAR TSXFA IBRS STIBP L1DF SSBD
