macOS App Notarization Guru Needed -- 2
Budget: $10 – $30 USD
macOS App Code Signing & Notarization Help (Developer ID / Keychain Issue)
Project Description:
I need an experienced macOS developer / build engineer to successfully code sign and notarize my macOS desktop app.
About the App:
Platform: macOS
App type: Python Tkinter app packaged as .app (via PyInstaller)
Output: .app (and optionally .dmg)
Goal: App should open on macOS without Gatekeeper warnings (Notarized Developer ID)
Current Problem
I have a Developer ID Application certificate with a valid private key and active Apple Developer account.
However:
codesign consistently fails with:
errSecInternalComponent
Warning: unable to build chain to self-signed root
This persists even after:
Recreating certificates
Re-importing keys
Fixing keychain ACLs
Setting key partition lists
Trusting Apple Root + Developer ID CA at system level
This appears to be a macOS Keychain corruption / signing environment issue, not an app code issue.
What I Need
I am looking for someone who can take over the signing & notarization and deliver:
Properly signed & notarized .app or .dmg
App opens without:
“App can’t be opened”
“Developer cannot be verified”
Gatekeeper blocks
What I Can Provide
Built .app file (PyInstaller output)
Source code (cant do even if needed)
Apple Developer access via:
Temporary team invite OR
App Store Connect API key
App-specific password for notarization
I will NOT share my Apple ID password.
Required Skills
macOS code signing & notarization
Apple Developer Program
codesign, notarytool, stapler
Experience with:
Python / PyInstaller apps OR
macOS app packaging
Familiarity with Keychain issues
Timeline:
Immediate
Prefer someone who can start today
Priority is getting this working correctly, not cutting corners
Important Note:
This is not a beginner task.
I am specifically looking for someone who has successfully notarized macOS apps before and understands Apple’s signing pipeline deeply.
