fseventer (as of Oct 2013) does run in osx 10.9 Mavericks

(In earlier developer previews it would not run due to a Apple code signing requirement bug.)

Currently untested in 10.10 Yosemite


  • Observes filesystem changes using the same underlying API as Spotlight
  • Provides a graphical representation of the file activity
  • Example use could be to determine what files are changed via software installation, preferences, etc
  • Requires admin access & will only work on Mac OS X 10.4+ i.e. “Tiger”, “Leopard”, or “Snow Leopard”

Screen Shot - treeview

Screen Shot - tableview and file inspector

Known Issues

  • Pre 2.7.0 versions must be copied to a disk where root permissions can be set

  • Keyboard support for home/end pageup/down, toggling between views, etc
  • The timeline view
  • The process view
