I'm running into 2 issues that I'm not sure how to solve regarding validating apps to publish to the Mac App Store.

A new Version of iTMStransporter is available on the early-access update channel. Specify '-updateChannel earlyAccess' on the command line to test it out.

---Irrelavant issue about sandbox---

Your version of iTMSTransporter will be updated in approximately in 2 days.

I have looked into the App Store and I have not found anything that seems relevant. Executing that command returns command not found: -updateChannel

This solved my problem:

1. Open terminal
2. navigate to /Applications/Xcode.app/Contents/SharedFrameworks/ContentDeliveryServices.framework/Versions/Current/itms/bin
3. Fill in ./iTMSTransporter -updateChannel earlyAccess in the cmd
4. Use transporter
