LazTranslator version 2.0.1 for MAC OSX 64 bit

I updated the lazTranslator application to version 2.0.1
In this new version I added:
- Preferences panel;
- play sound  of  text orgine;

As for OCR, for the moment the capture of the screen and the selection of an area does not work.
I'm trying to implement the function of MAC: capture area within the program, but I do not have enough documentation to launch the command from the terminal with a script (HELP ME).
