How to fix a Mac Application that’s not starting

Sometimes an application does not open, just jumps in the Dock a few times, then stops.

There may be lot’s of reason for that:

  • the app is incompatible with the OS you are running
  • damaged preferences
  • damaged application
  • file ownership rights not properly set
  • other

One of the ‘other’ reason is that you made some nasty modification to an application. In this case you need to make the app executable.

If the app is here: /Macintosh HD/Applications/

…then the file you have to make executable is is within >

enter in Terminal:

chmod +x /Macintosh HD/Applications/
