RepoBar fails to launch on macOS 26 (Tahoe)

[aaronvarga]

Description

RepoBar 0.2.0 fails to launch on macOS 26 (Tahoe). The app is blocked at the kernel level by AMFI (Apple Mobile File Integrity) due to code signature/entitlement validation failure. No "Open Anyway" option appears in System Settings > Privacy & Security.

Error

When launching via open -a RepoBar:

The application /Applications/RepoBar.app cannot be opened for an unexpected reason,
error=Error Domain=RBSRequestErrorDomain Code=5 "Launch failed."
UserInfo={NSLocalizedFailureReason=Launch failed.,
NSUnderlyingError={Error Domain=NSPOSIXErrorDomain Code=163 "Unknown error: 163"
UserInfo={NSLocalizedDescription=Launchd job spawn failed}}}

System logs

amfid: /Applications/RepoBar.app/Contents/MacOS/RepoBar not valid:
  Error Domain=AppleMobileFileIntegrityError Code=-413
  "No matching profile found"

kernel: (AppleMobileFileIntegrity) AMFI: When validating
  /Applications/RepoBar.app/Contents/MacOS/RepoBar:
  Code has restricted entitlements, but the validation of its code signature failed.
  Unsatisfied Entitlements:

kernel: (AppleSystemPolicy) ASP: Security policy would not allow process

Attempted workarounds (none worked)

• xattr -cr /Applications/RepoBar.app
• xattr -d com.apple.quarantine /Applications/RepoBar.app
• spctl --add (no longer supported on macOS 26)

Environment

• macOS: 26.3 (Build 25D125)
• RepoBar: 0.2.0 (installed via brew install --cask repobar)
• Architecture: Apple Silicon (arm64)

It appears macOS 26 has stricter AMFI enforcement and the app's provisioning profile / restricted entitlements need to be updated for compatibility.
