ITMSTRANSPORTER_FORCE_ITMS_PACKAGE_UPLOAD = false I resolved this issue by this env.

Hi, I had a same problem on last friday. I think the Transporter app has some problem. I solved it by following the steps below. Remove Transporter.app Install iTMSTransporter - https://itunesconnect.apple.com/WebObjects/iTunesConnect.woa/ra/resources/download/public/Transporter__OSX/bin/ Install the pkg mkdir -p /Applications/Transporter.app/Contents/itms/bin ln -s /usr/local/itms/bin/iTMSTransporter /Applications/Transporter.app/Contents/itms/bin/iTMSTransporter Maybe you need to add a path.
