I figured this out for my account after a bit of trial and error. I had typed... "Developer ID Application : Chilton Webb" ... and after running security find-identity in the terminal, I copy and pasted what I found: "Developer ID Application: Chilton Webb" Note the lack of a space ^^^^ after Application, before the colon. That was it. Good hunting, -Chilton

I have Google Fiber and if there's any kind of delay during an Xcode download, it fkn dies here too. So while I am not suffering to the same extent you are, I can definitely corroborate your experience. -Chilton

I've also seen this on a cell phone connection once a few months ago, and that time it was truly painful having to restart the download.

I am currently experiencing a problem where it appears that some of my plugins are not loading in the main app. Third party plugins are working just fine. Of course everything works fine on my system. It only fails on the test system with no debugger. I'm looking through your other documentation now. -Chilton

Hi Quinn, This is for a MacOS app. In the olden times I'd use a Tech Support Incident to get this resolved, but I'm not sure if that's even a thing anymore. In this thread, the suggestion was to "select an application bundle prefix that matched my team id". Maybe that's it? I say that because I have no idea where they're selecting or setting it. It's always the unknowns that get me, and this is an unknown :) https://developer.apple.com/forums/thread/666790 -Chilton

More info: This is a Unity app. If I build it using the standard Unity build system, and I code sign it using the various code sign, ditto, notarization, and staple means, I CAN make it build properly for outside of App Store cases. But I cannot make a build that the App Store will accept through Transporter. So, assuming my problem could be resolved if I built this through Xcode, I used Unity's option to build and deploy via Xcode. But the Xcode version gives me the "Invalid Provisioning Profile" error, if I try to push it to the App Store as well. *meanwhile, another Unity app I'm working on for iOS has been happily building and deploying to the App Store with absolutely no issues, but it's a completely different product, different bundle ID, etc. "I wish I had never come here, and I don’t want to see no more magic." -- okay I'm not at that point yet. I am happy to try literally anything :) -Chilton

Quinn, You've outdone yourself again. These are fantastic. I don't have an answer yet but I think you've given me every tool I will need to solve this. So thank you, in advance :) -Chilton
