# 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. | |

# 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. | |

# This uses local codesign. so it'll be valid ONLY on the machine you've re-signed with. | |

@mpielikis - I suspect your issue isn't related to script. Maybe release builds universal but debug only arm64? S1 v4 was never released as Apple silicon.
Also the script allow debug but isn't related to host scanning.
Thanks! This worked nicely for me with the Steinberg VST3PluginTestHost, using my arm64 MacBook Pro on Monterey👌🏻

Thanks for creating this tool! Unfortunately it doesn't work for me. I have MacBook with M1, I've tried running the script on Sudio One 4 and disabling the SIP in order to Debug VST3 audio plugin. I see that entitlements are added, but it has no effect. Only when I build the Release version of audioplugin the Studio One sees it.
