I'm running TexLive 2012 on MAC Mac OS X 10.7.5.
I used to simply press "Command+T" to typeset my .tex script. 

But now it shows "! LaTeX Error: File `ERROR:Systemcommandexecutionisdisabled(seePreferences).sty
' not found.Type X to quit or <RETURN> to proceed,
or enter new name. (Default extension: sty)"

This means I also need to press "enter" to complete the typeset. 

Can you please tell what is the problem, so I can avoid pressing the "enter" key.

Thanks !
