Sure, but allowing *any* old program to be debugged / decompiled in realtime is not the best for security implications, at least Apple thinks so. Your subject is a little misleading as the "Xcode debugger" is essential lldb. Xcode itself simply wraps lldb when debugging and provides a UI top interact with it. In fact, on a debug build crash in Xcode, you can enter lldb commands directly into the console, ie. "bt" will provide a backtrace directly. > How do people attach a debugger to pd to do development? "lldb" like "gdb" For quick tests of a known crasher, I usually use: make cd bin lldb pd This will use the system Tcl/Tk which has had issues for years now, but is enough for quick testing. For best testing, build the .app and invoke the pd binary inside it. For example: make make app lldb Pd-0.53-2.app/Contents/Resources/bin/pd Once lldb launches, you have to start the process: process launch When a crash happens, you can get the backtrace with "bt", change frames with "f #", and print variables via "v". If you have used gdb before, this is a helpful crib sheet: https://lldb.llvm.org/use/map.html <https://lldb.llvm.org/use/map.html> Note: If you are using a newer macOS system and want to *also* use a newer version of Tcl/Tk, build Wish.app first then use it to make the Pd .app bundle: ./macos/tcltk-wish.sh 8.6.12 produces a Wish-8.6.12.app. Next use it to build Pd .app with: ./mac/osx-app.sh -w Wish-8.6.12.app 0.53-2 Now you can change the C sources and rebuild with: make ./mac/osx-app.sh -w Wish-8.6.12.app 0.53-2 > Do I have to recompile pd myself as the long winded detour? If you want debugging symbols, yes. Fortunately it is relative easy to compile Pd so I don't consider it "long-winded." In fact, we have spent quite a bit of time to make this both possible *and* relatively easy.
