This post basically just a note for my self. In case I got the same condition in the next, it can help me to remember what I did in the past.
I got a condition which I have just changed my git password. Surely I cannot pull or push since my local credential was not valid anymore. When I run git config --list, I believe my git password stored on OS X Keychain. The simple way I do was running a command via terminal :
$ git config credential.helper osxkeychain
I was then prompted to input my username and password. By inputing my username and new password everything back to normal.
If you want it to apply globally just append parameter --global to the command.
$ git config --global credential.helper osxkeychain
