#206 QM 4.1.2 for Mac: can't open models via drag and drop as documented

[Ned Konz]

I just uninstalled QM 4.1.1 and installed QM 4.1.2 for Mac OS (I have High Sierra, v 10.13.3).

I followed the instructions in the QM manual about making a desktop alias and keeping QM in the dock, but neither shortcut accepted a drop of a .qm file.

Also, the Finder app icon in /Applications won't accept the drop of a .qm file.

There are no default file associations set for the QM application; adding an association for qm ('always open with') also doesn't work, because open -a qm /Users/ned/src/QP/qpcpp/examples/win32/dpp-comp/dpp.qm doesn't open the model file.

It does work when I do /Applications/qm.app/Contents/MacOS/qm /Users/ned/src/QP/qpcpp/examples/win32/dpp-comp/dpp.qm

The open -a command seems to need the --args parameter to actually pass the arguments to the application. Specifically, the following command line works:

open -a qm --args /Users/ned/src/QP/qpcpp/examples/win32/dpp-comp/dpp.qm

I'm not sure whether this is a bug (e.g., see bug17757).

At this point, it's not clear how to fix this problem inside the QM application for MacOS. Any suggestions/workaround for this issue would be appreciated.
