I’ve tested the example with a slight newer version of the example code (and an experimental version of PyObjC, but that shouldn’t matter here) and it works for me. I tested both with ‘python setup.py py2app -A’ and ‘python setup.py py2app’. I did have to ensure that the application was started in 32-bit mode, either by running from the Terminal as "arch -i386 dist/HotKey.app/Contents/MacOS/HotKey” or by by selecting “Open in 32-bit mode” in the Get Info popup in the Finder. The newer version is attached below and only changes the way code is imported, it no longer uses “from Cocoa import *” (that also shouldn’t affect to way the application is launched, but should result in a faster launching application). I really don’t understand why an alias build doesn’t work for you even though just running “python HotKey.py” does seem to find PyObjC (otherwise you’d have gotten an import error there as well, and instead of the error message from the AppKit framework). Are you really sure that you used the same python executable for running HotKey.py directly and for running “python setup.py py2app -A”? You could add “import sys; print(sys.prefix)” to the start of HotKey.py to make sure, that should print the same prefix in both ways of running the script.

The usual problem is that the python you're using to run py2app is a different one than you expect (e.g. one without pyobjc installed), but that doesn't seem to be the problem here because you don't get an ImportError when running the script from the command-line. > > Ronald > > P.S.
