Several weeks ago I updated to the latest Git for Windows (when prompted by the version check). At the time I noticed: $ git commit -S -am "Fix unset MAKE variable in test scripts" gpg: signing failed: No pinentry gpg: signing failed: No pinentry error: gpg failed to sign the data fatal: failed to write commit object I got to look at it today. On Windows: $ cat ~/.gnupg/gpg-agent.conf pinentry-program /usr/local/MacGPG2/libexec/pinentry-mac.app/Contents/MacOS/pinentry-mac Jeff
