** The application must be signed, which the project build should do automatically. If you face issues, check that the build resulted in a "codesign" call. The codesign call also includes the right "entitlements" via the entitlements.plist that is included in the sources, which sets "get-task-allow". This is required to get "attachable" permission to your application (as of macOS 12.5, see [https://developer.apple.com/library/archive/technotes/tn2415/_index.html#:~:text=and%20UIPasteboard%20sharing.-,get%2Dtask%2Dallow,-The%20boolean%20value Apple official documentation]).

** Be sure to enable core dumps with "ulimit -c unlimited". Note that this is limited to the shell that you called that in, so run it in Terminal and start the application (or Qt Creator and from there the application) from that Terminal (e.g. with "open <path>/Qt\ Creator.app"). | |||

"Step into" a couple of times. Can you step into Qt source code (*.cpp file under QTDIR)?
(Mac: switch on 'Use Debug Versions of Frameworks' in run configuration. You need Qt sources.) |

Test debugging helpers/python lldb: Do classes like QImage or std::string show beautiful information instead of the raw structure? | automated | |
