When I tried push to my repository I got an error
>>>git push -u origin master
error: git-credential-osxkeychain died of signal 11
After searched web, I found this blog post. It seems to be that there's a bug in git-credential-osxkeychain so simply replace that with new one on S3.
>>>which git git-credential-osxkeychain
/usr/local/git/bin/git-credential-osxkeychain
>>>curl -O http://github-media-downloads.s3.amazonaws.com/osx/git-credential-osxkeychain

>>>mv git-credential-osxkeychain /usr/local/git/binn
>>>chmod 755 /usr/local/git/bin/git-credential-osxkeychain
After did above, I successfully pushed my git repo.
