Jerome,
Unfortunately, I cannot start this version of Hatari. I think this is the important part of the crash report.
Dyld Error Message:
Library not loaded: /opt/local/lib/libreadline.6.2.dylib
I do have XQuartz installed correctly now, but it does not include the libreadline that you have.
I have also seen the crash and missing status bar text (I still see the indicator lights though) along with the missing SDL text in the F12 menu. However, since I never owned a Falcon, I really do not spend time using that mode so I admit that the problems do not affect me.
If you intend to move the .hatari directory to /Application Support/Hatari (or do you mean ~/Application Support/Hatari?), this needs to be in a readme. Even though there was a complaint on Atari-Forum, I am used to seeing hidden "dot" directories in my home.. Since I realize that you probably cannot change the hidden cfg file into a Mac preference file, I am concerned that changing the location of this directory might affect other more technical OS X Hatari users that are used to looking for .hatari in their home directory.
