Show notes synopsis:

Home Folder:
-Most of the evidence is located in the Userʼs Home Folder
-Majority of the Preference PLists with user-specific settings are in 
 User/Library/ Preferences

 -User Logs:
  -Indicative of the userʼs activity
  -Not system activity, but user specific logs

-Preferences:
 -PLists files or proprietary format files for the User
 -Contains configurations and settings for the User
 -I.E. Online activity, buddy lists, email, logins, etc.

-Application Support:
 -Mozilla Cache, iPhone backup files from MobileSync folder  -Application PLists with information

LEOPARD:
-Disk Arbitration looks at devices and mounts the device and makes icon 
  to access this device available to the user
-On Boot, Disk Arbitration recognizes the internal hard drive. Recognizes
  file system. Mounts partitions on desktop.
 -In order to prevent writes, we must prevent the mount.

 -To turn off Disk Arbitration, enter Terminal and type:

sudo launchctl unload System/Library/LaunchDaemon/com.apple.diskarbitrationd.plist

-Now when you connect a disk, the disk will not mount

-To turn back on, enter Terminal and type:
sudo launchctl load System/Library/LaunchDaemons/com.apple.diskarbitrationd.plist

or Reboot system and diskarbitration will become active again

TIGER:
-Not controlled by LaunchCtl process
-Need to move the PList from one location to another

-Method:
1. Make copy of the diskarbitrationd.plist
2.Once the copy is made, use the remove command in Terminal to delete  
   the com.apple.diskarbitrationd.plist from the /etc/mach_init.d folder
3.Reboot system
4.Only OS Boot partition will mount.

To UNDO, Copy the diskarbitrationd.plist back to the /etc/mach_init.d  
   folder and reboot the system.

PList(s) of the Week(PLOW):

User/Library/Safari:

Bookmarks.plist:
 -User created/maintained bookmarks

Episode 1 Show Notes (Download at: Show Notes)


GOLDEN RULE: Use OPTION key to boot first and confirm no Firmware Password

OFP: Prevents any other startup option other than "option" or "startup disk".

If OFP is active and you attempt alternative boot sequence, the system will default to  the normal “Startup Disk” and possible writes will be made.
-Dont want to make writes....

1. Boot with option key to confirm Open Firmware Password exist
2. To get around:
    A. Pull hard drive and image via write block (24 screws or less)

    B. Reconfigure the RAM:
        1) Shut down
        2) Disconnect power (if laptop remove battery)
        3) Remove stick or add stick of RAM to reconfigure
        4) Close up, connect battery/power
        5) Command+Option+P+R key all at once "Vulcan Death Grip"
        6) Listen for 3 Chimes-Indicates reset
        7) Restart and use Option key to check

NOTE: Time will be reset. The clock will possibly be off.
             Logs may be important.
