• OS X v10.6.8 or later
• 2 GB of memory
• 8 GB of available space
• Some features require an Apple ID
• Some features require a compatible Internet service provider

What four preparation steps must you take before upgrading a system with OS X Mountain Lion?
Four steps you should take before upgrading a system to OS X Mountain Lion are:
• Install Apple software and firmware updates • Verify application compatibility
• Back up important files and folders
• Document critical settings.
How can you identify if a Mac requires a firmware update?
You can identify a Mac computer’s firmware version by opening the full system report in the System Information application or System Profiler application. You can verify if a Mac computer’s firmware is up to date by visiting the Apple support website, which maintains a list of available firmware updates.
What are the advantages and disadvantages of using a single- partition disk with OS X? How about a multiple-partition disk?
Single-partition drives are easier to set up initially, but they aren’t as flexible for administration and maintenance. Multiple-partition drives require repartitioning during setup but provide several separate partitions, which can be used to segregate user data and host multiple operating systems.
How can you acquire the OS X Mountain Lion installation assets?
the OS X Mountain Lion installer can be purchased and downloaded only from the Mac App Store.
What options can you select from during the OS X Mountain Lion installation?
During installation of OS X Mountain Lion, the only optional choice is to define an installation destination other than the Mac computer’s current default system disk.
What key features do you gain by setting up iCloud?
iCloud is a free service from Apple that provides cloud storage and communication services for applications (including Mail, Contacts, Calendar, Reminders, Notes, Safari, Photo Stream, and any other applications that support iCloud integration). iCloud also provides Find My Mac technology for help locating a lost or stolen system.
What three primary sources can Migration Assistant pull
Migration Assistant can migrate information from other OS X systems, other Windows systems, and other disks (including Time Machine backups).
What are the five System Preferences categories?
System Preferences is divided into five categories, from top to bottom: Personal, Hardware, Internet & Wireless, System, and Other.
How do the four default System Preferences categories differ?
Generally, Personal preferences affect only a single user; Hardware preferences affect hardware and peripheral settings; Internet & Wireless preferences affect personal and system network settings; and System preferences affect all users and often require administrative access.
What is a configuration profile? How are configuration profiles managed?
A configuration profile is a document, with the filename extension “.mobileconfig,” that contains system settings as defined by an administrator. Opening a configuration profile prompts the system to install the profile and configure the settings. Installed configuration profiles are managed via the Profiles preference pane.
Where can you locate the system version number, build number, and serial number? What is the significance of these numbers?
The system version number, build number, and serial number are located in the About This Mac dialog or login screen. The system version number defines the specific version of OS X currently installed. The system build number is an even more specific identifier used primarily by developers. Finally, the system serial number is a unique number used to identify a specific Mac.
What utilities are available when started up from OS X Recovery?
The OS X Recovery system provides access to Restore From Time Machine Backup, Reinstall OS X, Get Help Online, Disk Utility, Startup Disk, Firmware Password Utility, Network Utility, Terminal, and Reset Password.
What two resources does the local hidden OS X Recovery HD need in order to reinstall OS X Mountain Lion?
The local hidden OS X Recovery HD doesn’t include the OS X installation assets. Thus, reinstalling OS X Mountain Lion from here requires high-speed Internet access and the ability to verify access to the installation assets. Upgraded Mac computers are verified by entering the Apple ID used to purchase OS X Mountain Lion. Conversely, verification is automatic for Mac computers that included OS X Mountain Lion.
What two methods can be used to create an external OS X Recovery disk?
The OS X Recovery Disk Assistant can create a minimal OS X Recovery disk. A full OS X Recovery disk can be created by using Disk Utility to copy the Install OS X Mountain Lion application assets to the disk.
Which application can you open to initiate Apple software updates?
All software updates are handled via the Mac App Store.
By default, are any items automatically installed via Software Update?
Important system files and security updates are automatically
installed after a period of several days.
Which applications are used to manually acquire and install OS X software updates?
OS X software updates can be downloaded from the Apple support website using any modern web browser. Updates take the form of installation packages that are installed via the Installer application.
How can you find which installations have taken place on the system?
The Installations section of System Information shows the history of all software installed via the Mac App Store or OS X Installer.
What are the five types of user accounts in OS X? How are they different?
Standard is the default account type; administrative users can make changes to the system; a guest user doesn’t require a password; sharing only users can access only shared files; and the root user has unlimited access
What are some security risks associated with each type of user account?
Standard user accounts are very secure, assuming they have good passwords. Administrative users can make changes that may negatively affect the system or other user accounts. A guest user could potentially fill shared folders with unwanted files. Sharing only users are generally very secure as long as you don’t allow excessive access to your account. The potential for mayhem with root user access is nearly unlimited.
What are account attributes?
Account attributes are the individual pieces of information used to define a user account. Examples include full name, account name, user ID, Universally Unique ID (UUID), group, and home folder.
How can you limit a user account from having full access to all applications?
Parental controls can be used to further limit a user account. Examples include enforcing a simple Finder, limiting applications and widgets, setting time limits, and content filtering for several applications included in OS X.
What types of contention issues can occur when fast user switching is enabled?
Resource contention occurs when fast user switching is enabled and a user tries to access an item another user already has open in the background. Document contention occurs when a user attempts to open a document another user has already opened. Peripheral contention occurs when a user attempts to access a peripheral already in use by another user’s open application. Application contention occurs when the second user attempts to access an application designed to run only once on a system.
What security risk related to storage can occur when fast user switching is enabled?
When fast user switching is enabled, all users are allowed to see other users’ locally connected disks.
What default folders make up a user’s home folder? What are some optional folders in a user’s home folder?
The default folders in a user’s home folder are Desktop, Documents, Downloads, Library (hidden), Movies, Music, Pictures, and Public. Optional home folder items include Applications and Sites folders.
When deleting a local user account, what three options does the Users & Groups preference provide for dealing with the user’s home folder content?
When deleting a local user account, you can archive the home folder content into a compressed disk image, leave the home folder content in the /Users folder, or delete the home folder content. Optionally, you can perform a secure erase on the home folder content.
How do you associate a new local user account with a manually migrated or restored user’s home folder?
Before the local user account is created on a system, you must first copy the restored user’s home folder to the /Users folder. Then once you create the new user in the Users & Groups preference pane with the same account name, the system prompts you to associate the new account with the restored home folder.
What does the master password do?
The master password can only be used to reset local account passwords.
