Can't tell if apache is running on Mavericks Why can't I see httpd in activity monitor nor top in Mavericks?
Activity Monitor default view of the process list is 'My Processes':



Switch to 'All Processes' in the menubar to additionally see other users' - like root or _www - processes:


Check again in 'Activity Monitor'




If it's still not visible it's not running.

httpd not running is default for Mavericks client and server.
