# Simple Utility Script for allowing debug of hardened macOS apps. | |
# This is useful mostly for plug-in developer that would like keep developing without turning SIP off. | |
# Credit for idea goes to (McMartin): https://forum.juce.com/t/apple-gatekeeper-notarised-distributables/29952/57?u=ttg | |
# Update 2022-03-10: Based on Fabian's feedback, add capability to inject DYLD for sanitizers. | |
# | |
# Please note: | |
# - Modern Logic (on M1s) uses `AUHostingService` which resides within the system thus not patchable and REQUIRES to turn-off SIP. | |
# - Some hosts uses separate plug-in scanning or sandboxing. | |
# if that's the case, it's required to patch those (if needed) and attach debugger to them instead. | |
# | |
# If you see `operation not permitted`, make sure the calling process has Full Disk Access. | |
# For example Terminal.app is showing and has Full Disk Access under System Preferences -> Privacy & Security | |

It doesn't seem to work anymore with Ableton Live 12 (release version) :'(
It'll be helpful to have more details.
Anyway, I don't have Live 12 but the trial version allows re-signing just fine...
Grabbing entitlements from app...
Executable=/Users/talaviram/Downloads/Ableton Live 12 Trial.app/Contents/MacOS/Live
Patch entitlements (if missing)...
Add: ":com.apple.security.cs.disable-library-validation" Entry Already Exists
Add: ":com.apple.security.cs.allow-unsigned-executable-memory" Entry Already Exists
Re-applying entitlements (if missing)...
/Users/talaviram/Downloads/Ableton Live 12 Trial.app: replacing existing signature
Removing temporary plist...
Ah sorry, I forgot.
sudo xattr -rc Ableton\ Live\ 12\ Suite.app
did the trick :)
