tmdiagnose -- gather information to aid in diagnosing Time Machine issues SYNOPSIS
tmdiagnose -h tmdiagnose [-d seconds] [-f path] [-m] [-r] DESCRIPTION
The tmdiagnose tool gathers system and backup information in order to assist Apple when investigating issues related to Time Machine. A great deal of information is harvested, spanning system state, system and backup configuration, and snapshot details. What tmdiagnose Collects: o A spindump of the system o Several seconds of fs_usage ouput o Several seconds of top output o Individual samples of backupd and Finder o Power Management state and logs o IOKit registry information o A netstat inspection o A list of all open files on the system o All system logs o All kernel logs o All install logs o All fsck_hfs logs o All WiFi logs o Disk Utility logs for all local users o The system migration log o All spin and crash reports for the following processes: backupd mds diskimages-helper DesktopServicesHelper newfs_hfs NetAuthSysAgent o Recent spin and crash reports for the following processes, for all local users: Finder Locum System Preferences SystemUIServer iPhoto Mail MailTimeMachineHelper Address Book o Basic information about reachable AirPort and Time Capsule devices o The FindSystemFiles cache o Information about disks and mounted network shares o Information about attached disk images o A System Profiler report o A list of software that has been installed via the darwinup tool o Time Machine preferences, caches, and configuration information o 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 available. What tmdiagnose Doesn't Collect: o No user files are harvested from within backups o No authentication credentials are harvested from the system o No authentication credentials are harvested for reachable AirPort and Time Capsule devices OPTIONS
-h Print full usage. -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 and Finder. -r Do not reveal the diagnostic in Finder when finished. EXIT STATUS
tmdiagnose exits with status 0 if there were no internal errors encountered during the diagnostic, or >0 when an error unrelated to external state occurs or unusable input is provided by the user. Mac OS X 6 September 2011 Mac OS X

SubmitDiagInfo -- sends diagnostic information to Apple SYNOPSIS
SubmitDiagInfo is a system process which runs periodically. If the user has opted-in for automatic reporting of diagnostic and usage infor- mation, then SubmitDiagInfo collects and sends to Apple any recent diagnostic information which has not yet been sent to Apple. SubmitDiagInfo also cleans up any diagnostic and usage information which was created more than one month ago and is no longer needed. Sending diagnostic and usage reports to Apple helps us improve the quality and performance of our products and services. It helps Apple identify common usage trends and issues that enable us to allocate our resources efficiently, and it helps us provide better support services to you and other customers. All of the diagnostic and usage information is collected anonymously from your computer in a way that does not personally identify you. Reports may include the following information: - Details about application or system crashes, freezes, or kernel panics. - Information about events on your computer (e.g. whether a certain function, such as waking your computer was successful or not). - Usage information (e.g. data about how Apple and third party software, hardware and services are being used). Automatic reporting of diagnostic information is off by default and no information is sent to Apple unless a user has opted-in to automatic collection of diagnostic information. A user is offered the opportunity to opt-in for automatic collection of additional diagnostic and usage information after the user has manually sent a crash, hang or panic report to Apple. Users may at any time opt in or out of automatic reporting in the Security & Privacy pane of the System Preferences application under the "Privacy" tab. All diagnostic and usage information which is eligible for automatic reporting is visible in the Console application under the "DIAGNOSTIC AND USAGE INFORMATION" heading in the application's sidebar. (The information appears here even if a user has not yet opted-in for automatic reporting.) For security purposes, some system diagnostic information will only be visible to admin users and will only be submitted when an admin user is logged in. Users who need technical support should use or other authorized support channels. Developers who are ADC mem- bers should submit bug reports using in order to allow for two way communication between Apple and the bug reporter. SEE ALSO
