     and backup configuration, and snapshot details.

   What tmdiagnose Collects:
           •   A spindump of the system
           •   Several seconds of fs_usage ouput
           •   Several seconds of top output
           •   Individual samples of backupd, mtmd, mtmfs, and Finder
           •   Power Management state and logs
           •   IOKit registry information
           •   A netstat inspection
           •   A list of all open files on the system
           •   All system logs

           •   All fsck_hfs logs
           •   All WiFi logs
           •   Disk Utility logs for all local users

                  diskimages-helper
                  Locum
                  newfs_hfs
                  NetAuthSysAgent

           •   Recent spin and crash reports for the following processes, for all local users:
                  Finder
                  Locum
                  System Preferences

           •   Information about disks and mounted network shares
           •   Information about attached disk images

           •   A list of software that has been installed via the darwinup tool
           •   Time Machine preferences, caches, and configuration information
           •   Comprehensive information about Time Machine backups and snapshots

     The high-level backup structure for the current machine directory is recreated inside the diagnostic
     bundle, including the capture of various Time Machine log files contained within snapshots. Items in
     this "skeleton" structure have on them the extended attributes of the originals. Recreations of local
     snapshots are also captured in the same manner.

     The tmdiagnose tool will run the Spotlight diagnostic tool mddiagnose automatically, if it is avail-able. available.

           •   No authentication credentials are harvested for reachable AirPort and Time Capsule devices

OPTIONS

     -d sec  Delay the start of the diagnostic by sec seconds. The system alert sound will play two times
             when the diagnostic begins.
     -f path Write the diagnostic to the specified path.
     -m      Gather memory diagnostics for backupd, mtmd, mtmfs, and Finder.
