Blur Background on Mac OS

I am using a Macbook Pro to work remotely.  The blur background feature is helpful, but it appears to be absent in Teams for Mac.  I noticed the blur feature support page says it's not available on L...

    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 That's weird. I used to have the background blur option avaiable on my iMac teams app, but it's gone now. I checked the terminal command line and do not show AVX2.0 either.

    manoelguedes, I just saw your comment. I had the same experience--the blur working at one point, and then disappeared. Did you ever get that resolved? I have a MacBook Pro (Retina, 13-inch, Early 2013) with 3 GHz Dual-Core Intel Core i7. And the result I get from sysctl -a | grep machdep.cpu.features is this:

     

    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

      What’s the output of this command?
      sysctl -a | grep avx2

    manoelguedes I see the same thing on my 2013 Macbook Air.
    The blur feature in Teams was present and worked a couple weeks ago but it disappeared after an update.
    Looks like Microsoft chose to disable it if you only have AVX1.0.

      kathysgeek I'm sorry, however I don't believe taht's the reason. It is working for me on my MacBook Pro and it has only AVX1.0. Something else nedds to be there.

        Matu_ So it is working for you now?  It was not working in your 4-1-20 message -- right?

        Would you mind sharing the output for the following terminal command?

        sysctl -a | grep machdep.cpu.features
