1. Locate system version - build number - serial number location
Users don't traditionally need access to them - and if they do - they can use Terminal.
About this mac or system profiler. System is general release number - build is specific - and serial number represents the machine.
It will allow any user to search any attached non-system volume if ownership is ignored.
It has to copy the entire thing over again on each change.


2. 3 Main components of a typical command

5. Absolute path
Check for firmware updates - verify app compatibility - back up files - document critical settings
Users' public folders
A driver is a piece of software designed to facilitate the communication between Mac OS X and the peripheral. There are kernel extensions - framework plug-ins - or stand-alone applications.

Parental controls
Common UNIX Printing System (CUPS) manages all printing and faxing for the system.
Every home folder has the public folder and dropbox folder whereas all other home folders are protected.
1.) Create a plain text file w/ the 2.) Make the first line #!/bin/bash 3.) Change the permissions to allow execution


15. What items are not loaded when Mac OS X safe boots?

IP addresses identify the location of a specific network device. Subnet masks are used by network devices to identify their local network range. IPv4 addresses are a 32-bit number represented in 4 groups of four octets separated by periods. 0-255.
User preferences are in ~/Library and the format is often Property List - which is just a special XML file.

32. How does the spotlight search service use metadata?
Using information provided by the dynamic network services discovery protocols. Computers providing services appear as resources whereas service discovery zones or workgroups appear as folders.
Safe boot refers to when the system is starting up - safe mode is when the system is actually running - and safe login is when the system starts up the user session.
Local accounts are just for that Mac - network accounts are available anywhere on the network - and Mobile accounts create a cached local copy of a network account for offline access.
The spotlight search service creates index databases of file system metadata so that it can perform normally time-intensive searches nearly instantly.

The network service operates or broadcasts on a network port.
Check for firmware updates - verify app compatibility - back up files - document critical settings

Restart the app - try another document - try another user account - check log files - delete caches - replace preferences - and replace app resources.


36. What steps should you take when troubleshooting app issues?
It's used to verify or repair the directory structure of a volume which contains all the information used to locate files and folders on the volume.
Restart the app - try another document - try another user account - check log files - delete caches - replace preferences - and replace app resources.
