问题
My team share one apple developer certification, other team members can import it properly, but on my MAC, it will always report error "This certificate was signed by an unknown authority", I am not sure whether it dues to my side KeyChain Access issue, verify/repair doesn't find any defect.
Still not found solution after many try, any suggestion please share? I just wonder how to remove KeyChain Access then install a new one?

I resolved my issue by importing the required certificates into my login keychain.
