I did the usual SMC and NVRAM reset... nothing works... i.e. still USB-c left side only issues
Tried safe mode... same UCB-C left side problem.
Then I tried clean install of High Sierra 10.13.1 Here's the read-out from EtreCheck
(Also was able to do clean install of Sierra 10.12.6 (It was shipped w/Sierra, I think... did an internet restore) EtreCheck seems to be clean too... )
EtreCheck version: 3.4.6 (460)
