And GPU Panic have been happened.
GPU was broken when I checked My Mac by AHT (Apple Hard Test).
But I was able to use gfxCradStatus v2.4.3i,
So I am using only iGPU.
The following information is error code.
*** Panic Report ***
panic(cpu 2 caller 0xffffff7f8b9eab7e): "GPU Panic: [<None>] 3 3 7f 0 0 0 0 3 : NVRM[0/1:0:0]: Read Error 0x00000100: CFG 0xffffffff 0xffffffff 0xffffffff, BAR0 0xd2000000 0xffffff912482c000 0x0a5480a2, D0, P3/4\n"@/Library/Caches/com.apple.xbs/Sources/AppleGraphicsControl/AppleGraphicsControl-3.14.33/src/AppleMuxControl/kext/GPUPanic.cpp:127
AppleGraphicsControl was updated from 3.14.29 to 3.14.33.
This update may fix that Display of MacBook Pro 2016 is disturbed.
