hi, team, we used the py2app to build the mac app, the app works well before the codesign. But when I codesign it with the --options runtime the app can't startup. with the below error: /petoi-mac-app/Petoi\ Desktop\ App.app/Contents/MacOS/Petoi\ Desktop\ App ; exit; Traceback (most recent call last): File "/Petoi Desktop App.app/Contents/Resources/__boot__.py", line 147, in <module> _setup_ctypes() File "/petoi-mac-app/Petoi Desktop App.app/Contents/Resources/__boot__.py", line 140, in _setup_ctypes from ctypes.macholib import dyld File "<frozen importlib._bootstrap>", line 983, in _find_and_load File "<frozen importlib._bootstrap>", line 967, in _find_and_load_unlocked File "<frozen importlib._bootstrap>", line 668, in _load_unlocked File "<frozen importlib._bootstrap>", line 638, in _load_backward_compatible File "ctypes/__init__.pyc", line 551, in <module> File "ctypes/__init__.pyc", line 273, in _reset_cache MemoryError 2024-02-21 19:57:09.168 Petoi Desktop App[93968:1375266] Launch error 2024-02-21 19:57:09.168 Petoi Desktop App[93968:1375266] Launch error See the py2app website for debugging launch issues But if I removed the --options runtime I got the Notarizing Error below. { "severity": "error", "code": null, "path": "PetoiDesktopInstaller.pkg/PetoiDesktopInstaller.pkg Contents/Payload/Applications/Petoi Desktop App.app/Contents/MacOS/Petoi Desktop App", "message": "The executable does not have the hardened runtime enabled.", "docUrl": "https://developer.apple.com/documentation/security/notarizing_macos_software_before_distribution/resolving_common_notarization_issues#3087724", "architecture": "x86_64" } I am looking forward to your insightful reply.
