"code object is not signed at all In subcomponent" error after High Sierra update.

Hi there, I have updated my system to High Sierra a few days ago, and now I can’t sign my apps anymore.

I’ve tested everything I could think off:

• updated certs
• updated provisioning
• updated dependencies
• delete everything and pull from scratch
• I will try to get a Sierra MBP to test the signing, to be sure it’s really coming from HighSierra.

Always get the same error on the three Electron helpers.

• MyApp.app/Contents/Frameworks/MyApp Helper EH.app/Contents/MacOS/MyApp Helper EH
• MyApp.app/Contents/Frameworks/MyApp Helper NP.app/Contents/MacOS/MyApp Helper NP
• MyApp.app/Contents/Frameworks/MyApp Helper.app/Contents/MacOS/MyApp Helper

I don’t know what to do anymore.

Here’s the full error:

../release/MyApp-mas-x64/MyApp.app/Contents/Frameworks/MyApp Helper.app/: code object is not signed at all
In subcomponent: /Users/yoann/dev/myapp/release/MyApp-mas-x64/MyApp.app/Contents/Frameworks/MyApp Helper.app/Contents/MacOS/MyApp Helper

I’ve used a simple codesign script to pinpoint the problem :

#!/bin/bash

# Name of your app.
APP="MyApp"
# The path of your app to sign.
APP_PATH="../release/MyApp-mas-x64/MyApp.app"
# The path to the location you want to put the signed package.
RESULT_PATH="../release/$APP.pkg"
# The name of certificates you requested.
APP_KEY="3rd Party Mac Developer Application: Yoann MOINET (REDACTED)"
INSTALLER_KEY="3rd Party Mac Developer Installer: Yoann MOINET (REDACTED)"

FRAMEWORKS_PATH="$APP_PATH/Contents/Frameworks"

codesign -s "$APP_KEY" -f --entitlements "../build/child.plist" "$FRAMEWORKS_PATH/Electron Framework.framework/Versions/A/Electron Framework"

codesign -s "$APP_KEY" -f --entitlements "../build/child.plist" "$FRAMEWORKS_PATH/$APP Helper NP.app/Contents/MacOS/$APP Helper NP"
codesign -s "$APP_KEY" -f --entitlements "../build/child.plist" "$FRAMEWORKS_PATH/$APP Helper NP.app/"
codesign -s "$APP_KEY" -f --entitlements "../build/child.plist" "$APP_PATH/Contents/MacOS/$APP"
codesign -s "$APP_KEY" -f --entitlements "../build/parent.plist" "$APP_PATH"

But the output is as follow:

Please note that my app has a ê in its name, if that could be relevent. But I never had any issue with this before High Sierra update.

Thank you for your help.

Got it to work.

It was indeed ê. I copied another ê displayed in the Finder, and used it in my app.

Apparently, ê isn’t supported by codesign, but ê is. Should have figured this out 🙃

It is now working.

@yoannmoinet No worries! 👍 And I’m not very sure… But I’ll find some time to try to devise a workaround for unicode normalization. Let’s keep the issue open for some time until a fix is available.
