GPG signing of GIT commits works in terminal but not in Intellij Idea.
gpg failed to sign the data fatal: failed to write commit object

If you have working GPG signing of your GIT commits in terminal but not in Intellij Idea you can use pinentry-mac. Don't forget to update your gpg.conf and gpg-agent.conf files as well.
brew install pinentry-mac
echo "no-tty" >> ~/.gnupg/gpg.conf
echo $(which pinentry-mac) >> ~/.gnupg/gpg-agent.conf
