I’m hitting a “validation failed” road-block when I try to upload my macOS build to TestFlight. The build launches fine locally, but Transporter/Xcode refuses to accept it during submission. I need someone who can dig into the package, pinpoint the exact cause—whether it’s code signing, entitlements, or configuration—and then guide me to a clean, re-signed build that Apple’s validation will happily ingest. Here’s what I expect: • Inspect the project settings, certificates, and provisioning profiles. • Repair whatever is triggering the upload validation error. • Provide a short write-up of the fixes you applied so I can repeat the process next release. You should be comfortable with Xcode’s Organizer, Transporter, certificate management, and macOS entitlements. A quick turnaround would be ideal because I’m holding back a TestFlight round until this passes. Please prove support on Google Meet.
