Best practice to allow 3rd party app to read messages file.

csdiagnose

csdiagnose(1)						    BSD General Commands Manual 					     csdiagnose(1)

NAME

     csdiagnose -- collect information needed to diagnose CoreStorage volumes

SYNOPSIS

     csdiagnose [-f path] [-h] [-v] [dev ...]

DESCRIPTION

     csdiagnose collects information to help Apple investigate issues related to CoreStorage (File Vault 2, Fusion Drive, File Vault Everywhere,
     etc).  This tool invokes sudo, so you will be asked to authenticate.

     This script requires csgather(1) to be installed in the PATH.

     If dev is not given, all disks in the system will be inspected.  This is the recommended method of invoking csdiagnose.

     Advanced users can provide a list of dev in the form of disk1 or disk1s2.	Only information of the given dev is collected.  To fully collect
     information of a CoreStorage volume, the CoreStorage Physical Volume (i.e., the Apple_CoreStorage partition), the Apple_Boot partition after
     the physical volume, and the Logical Volume published by CoreStorage (which can be found out using the "diskutil cs list" command) should all
     be provided on the command line.

     The following information is collected:

	   1.	OS version.

	   2.	system logs, kernel logs, install logs, filesystem logs, and other useful information for CoreStorage debugging from /var/log.

	   3.	output of "diskutil list".

	   4.	output of "diskutil cs list".

	   5.	output of "mount -t hfs".

	   6.	"csgather -G" of every Apple_CoreStorage partition, which includes the CoreStorage metadata.  If a list of dev is provided, only
		information on the partitions included in the list will be collected.

	   7.	EncryptedRoot.plist of every Apple_Boot partition.  If a list of dev is provided, only information on the partitions included in
		the list will be collected.

	   8.	timestamps of the files relevant to kextcache/kextd.

     The following user information is contained in the collected file:

	   1.	Number and types of disks attached to the system.

	   2.	The volume names, UUIDs, and size of each partition.

	   3.	Encrypted versions of the volume key(s) that unlock the encrypted disk(s) attached to the system.  Refer to csgather(1) for what
		information could leak from the volume key(s).

	   4.	User names, pictures, and password hints for the users.

     No other user information (such as directory structures, file names, file content, etc) is collected.

     The following options are available:

     -h       Show this help information.

     -f path  Specify an output path which will hold the file generated by this script.  By default this will be the user's Desktop folder.  The
	      given path must already exist.

     -v       Verbose mode, which prints every command it invokes.
