 While it is possible to access Xgrid from the command line , the Xgrid graphical user interface , a program bundled with Mac OS X Server and , as of March 2009 , available online , is a much more efficient way of administering an Xgrid system .

This decision limited the efforts of the computer community to embrace the platform . Eventually , Apple released the Mac OS X Server Administration Tools to the public , which included the Xgrid administration application bundled with Mac OS X Server .
