[GRASS-web] software error

[15652984039 at sina.cn]

 Hi, 	I just want to use GRASS software for MAC, but after double click on the short cut, the programme did not startup, instead, I saw a text report said "Error in GUI startup. If necessary, please report this error to the GRASS developers.
Switching to text mode now.


Hit RETURN to continue..." 
its difficult for me to understand the real meaning of the text and to resolved the problem. 
and my system was macOS Sierra 10.12.1 just update for few days. 
thank you very much.
Wen
