Could you provide more informations about the CPU? Your CPU may not support some instructions (I guess it was caused by AVX).

My MacBook details is below: 型号标识符： MacBookPro10,1 处理器名称： Intel Core i7 处理器速度： 2.6 GHz 处理器数目： 1 核总数： 4 L2 缓存（每个核）： 256 KB L3 缓存： 6 MB 内存： 8 GB Boot ROM 版本： MBP101.00EE.B0B SMC 版本（系统）： 2.3f36 I hope these information will be helpful for the problem. thank you

I could't know which i7 you are using...

Could you run sysctl -a | grep machdep.cpu.features, and see what it output.

it says 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 SMX EST TM2 SSSE3 CX16 TPR PDCM SSE4.1 SSE4.2 x2APIC POPCNT AES PCID XSAVE OSXSAVE TSCTMR AVX1.0 RDRAND F16C

I guess what you are missing is FMA. You may build from source on your own machine or wait us to update the prebuilt binary.

thank you for your reply. i don't know how to build my own computer. Maybe i could wait for your binary.
