DeepFreezeMacOverview

AboutDeepFreeze

Deep Freeze Mac provides a completely non-restrictive working environment where there is no need

to be concerned about system damage or corruption; a simple restart eradicates all changes and ensures

that the standard system conﬁguration is available at all times. All changes to a computer are temporary

for that working session, including installation or removal of soware and application preference

conﬁguration. e need for IT professionals to perform rebuilds, re-image, or troubleshoot computers

is eliminated, resulting in a reduction in IT expenditures and an increase in computer uptime.

AboutAppleRemoteDesktop(ARD)

Apple Remote Desktop is Apple Computer’s complete desktop management solution for Mac OS X.

Faronics does not provide sales or technical support information for Apple Remote Desktop. More

information regarding ARD can be found at http://www.apple.com/remotedesktop.

CommandLineControlCapability

Tasks referred to in Appendix II for use with ARD can also be used in other third-party command line

control programs.

SystemRequirements

Deep Freeze Mac requires Mac OS X Tiger v10.4.11, Leopard v10.5.1 and up, or Snow Leopard v10.6.0

and up.

Deep Freeze Mac is a Universal application (Intel and PPC compatible).

InstallingDeepFreeze

Installation and conﬁguration of Deep Freeze Mac requires administrative access.

Deep Freeze Mac is downloadable via the Internet.

InstallingUsingaCustomizedDeepFreezeInstaller

A customized Deep Freeze Installer pre-conﬁgured with up to four usernames/passwords and

environment-speciﬁc application settings can be created using the Deep Freeze Assistant. Refer to

Appendix I for more information.

InstallingUsingtheBasicDeepFreezeInstaller

To install Deep Freeze on a single computer, complete the following steps:

Double-click the ﬁle DFX Version.pkg to begin the installation process. (Depending on

the conﬁguration, the ﬁle extension may not be visible). e installer is displayed. Click

Continue.

2. Read the Security Notice and click Continue.

3. Enter the License Key. If no License Key is speciﬁed, Deep Freeze will expire in 30 days.

4. Click Install and Deep Freeze is installed on the computer.

5. Click Restart to restart the computer.

Upon completion of a successful installation and aer the computer has been restarted, Deep Freeze is automatically

conﬁgured to put all drives and partitions into a Frozen state (unless otherwise conﬁgured through the Deep

Freeze Assistant). Drives and volumes that are to be put in a awed state can be speciﬁed using the Deep Freeze

Controller aer the install and restart following the install.

InstallingviaAppleRemoteDesktop

Deep Freeze is distributed as a standard installation package ﬁle and can therefore be installed over a

network using Apple Remote Desktop’s Install Packages command. Refer to the Apple Remote Desktop

user guide for more information. Refer to Appendix II for more information about controlling Deep

Freeze over a network using Apple Remote Desktop.

InstallingOverPreviousVersions

It is recommended that all previous versions of Deep Freeze Mac be uninstalled before installing a

newer version.

Deep Freeze Mac should not be booted in Target Disk Mode when Frozen. e cache

ﬁles will be invalidated and the program will become corrupt. If booting in Target Disk

Mode, ensure the computer is in a awed state.

UsingXgridwithDeepFreezeMac

In order for Xgrid to work properly on a Frozen Macintosh, the Xgrid folder must be symlinked to a awed

partition. When the computer is awed the /private/var/xgrid folder must be mapped to a awed location

(either the Global awSpace or a awed partition) and then symlinked to its original location.

Use terminal to do the following:

•

sudo cp -R /private/var/xgrid “some awed location” (another partition OR the Global

awSpace)

•

sudo rm -R /private/var/xgrid

•

sudo ln -s “some awed location”/xgrid /private/var/xgrid

9

UsingtheDeepFreezeController

If all drives and partitions are Frozen on a computer, a user can create, save, change, and delete ﬁles.

However, all changes are temporary, unless a awSpace or awed partition is being utilized. e

complete contents of a Frozen drive or volume are restored at restart.

All changes made in the Deep Freeze Controller only take eﬀect aer a restart.

OpeningtheDeepFreezeController

Use one of the following three options to open the Deep Freeze Controller:

•

Browse to Applications > Faronics > DFXControl.app and double-click.

•

Press Ctrl + Opt + Shi + F6.

3. Enter the License Key and click OK.

 11

BootControlTab

e Boot Control tab is used to change the status of Deep Freeze on a computer.

Use the three radio buttons provided to change the state of Deep Freeze:

• To set the computer to a Frozen state, choose Boot Frozen.

• To set the computer to a awed state for a speciﬁed number of restarts, choose Boot awed

on Next and specify the number of restarts (the number entered must be between 1-99).

• To set the computer to a awed state, choose Boot awed.

To restart the computer aer making changes, click Restart.

e following conﬁguration options are available:

• To hide the Frozen icon, select the Hide Frozen Icon in menu bar checkbox.

• To hide the awed icon, select the Hide awed Icon in menu bar checkbox.

• To display Frozen partitions without a Deep Freeze icon, select the Don’t badge Frozen partitions

checkbox.

• To set the workstations to restart when a user logs out, select the Restart instead of Log Out

checkbox.

• To display the workstation status (Frozen or awed) remotely in Apple Remote Desktop, select

the Show Status in Apple Remote Desktop checkbox and select the desired Information Field.

e workstation will now write Frozen or awed to the selected Information Field during boot

time.

To view this status information in Apple Remote Desktop, select Edit > View Options and select

the matching Computer Info Field (1–4). Workstations will now show their current status, and

groups of workstations can be sorted by this status column.

To save any changes made, click Apply; changes take eﬀect aer a restart.

12

DrivesTab

When the Drives tab is selected, Deep Freeze searches the computer and lists the drives present on a

computer. e drives listed can be put into a Frozen state or a awed state.

All drives on the computer are initially Frozen by default, unless otherwise speciﬁed in the Deep Freeze

Assistant (see Appendix I for more information). If you have created a partition to save user data and

did not designate it as a awed partition in the Assistant, put that partition in a awed state by

deselecting the corresponding checkbox in the Frozen column.

To save any changes made, click Apply; the changes take eﬀect aer a restart.

Removable media such as external FireWire or USB hard drives or keychain drives are

not displayed and can not be Frozen.

 13

ThawSpaceTab

e awSpace tab is used to create virtual awed partitions where documents and changes are

retained persistently on Frozen computers. Administrators can create a User awSpace for each User,

or a Global awSpace that all users can share. e awSpace tab displays only the users that have

awSpace.

Global and User awSpaces are easily distinguishable by the icons displayed in the Type column. e

icon represents the Global awSpace, and the icon represents a User awSpace.

awSpaces can be added or deleted from within the tab using the Add and Delete buttons. awSpaces

are sized in MB or GB and can range from 1 MB to 120 GB.

e computer must be in a awed state to create or modify a awSpace. If a awSpace was set up

using the Deep Freeze Assistant, a dialog (with a progress bar) appears stating that awSpaces are

being created. e Global awSpace and user awSpace are displayed as removable media on the

desktop. Other users’ awSpaces are displayed as a folder with restricted access.

A maximum of one Global and 32 User awSpaces can be created on each computer. e User awSpaces

are visible for mapping purposes. awSpaces appear as removable media on the Desktop. To have User

awSpaces tagged with the users’ chosen icons, select the Tag User awSpace with icon checkbox.

AddingaGlobalThawSpace

To create a Global awSpace, complete the following steps:

1. Click Add. e following dialog appears listing users without a awSpace:

14

2. In the dialog that appears, select Global awSpace from the list of User Names.

3. In the Size ﬁeld, enter the size of the awSpace and use the drop down menu to choose if it

is sized in MB or GB. e default size of the Global awSpace is 1 GB.

4. Click Add, or click Cancel to return to the tab without adding the awSpace.

5. In the awSpace tab, click Apply to create the new awSpace. A dialog prompts for the

administrative username and password.

AddingaUserThawSpace

To create a awSpace for a particular user on the drive, complete the following steps:

1. Click Add.

2. In the dialog that appears, select the user that the awSpace will be created for.

3. In the Size ﬁeld, enter the size of the awSpace and use the drop-down menu to choose if it

is sized in MB or GB. e default size of the User awSpace is 10 MB.

4. Click Add, or click Cancel to return to the tab without adding the awSpace.

5. In the awSpace tab, click Apply to create the new awSpace. A dialog prompts for the

administrative username and password.

A Global awSpace is accessible to all users. However, the user awSpace is accessible

only to the particular user. On Mac OS X 10.4, other users’ awSpaces will not be

displayed on the Desktop. On Mac OS X 10.5 and 10.6, when a user logs in, other users’

awSpaces will be displayed on the Desktop as a folder with restricted access.

It is not possible to remove an existing awSpace and retain its contents. Removing

a awSpace that has a user mapped to it will prevent the user from logging on to the

computer. It is recommended that the user be mapped to an alternate location before

the awSpace is removed.

RemovingaUserorGlobalThawSpace

To remove a User or Global awSpace, complete the following steps:

1. Select the awSpace to be deleted and click Delete. A dialog appears, asking for conﬁrmation

of the deletion.

2. Click Delete to permanently delete the awSpace or Cancel to return to the tab with the

awSpace retained.

3. Click Apply. A dialog prompts for the administrative username and password. e change will

take eﬀect on the next restart.

Alternatively, Deep Freeze Mac can be uninstalled in order to remove any awSpaces.

If you unmount the awSpace virtual drive, it is restored upon log out/log in or restart.

On a Frozen workstation, if a awSpace is physically deleted, the awSpace is restored

upon restart but the contents are deleted.

Before removing a awSpace, remove its proﬁle or folder mapping.

 15

ResizingaThawSpace

Once a awSpace is created, it can be resized by either increasing or decreasing the size of the

awSpace. Complete the following steps to resize one or more awSpaces.

1. Click awSpace. Select one or more awSpaces and click Resize.

2. e following dialog is displayed:

3. In the New Size ﬁeld, enter the size of the awSpace and use the drop-down menu to choose

if it is sized in MB or GB. e default size of a awSpace (User awSpace and Global

awSpace) is 10 MB.

4. Click OK to resize the awSpace(s), or Cancel to return to the tab without resizing the

awSpace(s).

5. In the awSpace tab, click Apply to resize the awSpace(s). A dialog prompts for the

administrative username and password. e change will not take eﬀect without a restart.

Resizing a awSpace is supported only on Mac OS X 10.6 or higher. Once a awSpace

is resized, the changes will take eﬀect only aer a restart.

16

LimitationsofResizingaThawSpace

e minimum awSpace size is the actual data space being used or 1 MB (whichever is higher) and

the maximum awSpace size is the actual partition size or 120 GB (whichever is lower). Increasing

the size of a awSpace does not have any limitations. However, reducing the size of a awSpace may

not be possible in some circumstances.

For example, a 10 MB awSpace is successfully resized when increased to 20 MB even if data is

stored on the entire awSpace. However, if a 10 MB awSpace is reduced to anything less than 10

MB, it may not be possible to resize a awSpace depending on where the data is written. If the data is

distributed over the 10 MB space, the awSpace cannot be resized. However, if the data is written only

at the start of the awSpace, it can be resized to the limit where there is continuous free space till the

end of the awSpace.

MaintenanceTab

e Maintenance tab is used to schedule a Maintenance Period when the computer will be automatically

awed to allow Apple Soware Updates to be permanently applied. e computer must be Frozen for

the Maintenance schedule to start.

CreatingandNamingMultipleMaintenanceSchedules

To create multiple individually named Maintenance Schedules, complete the following steps:

On the Maintenance Tab, click Add.

e default Schedule 1 tag appears in the list on the le side of the tab. Each additional schedule

added will have that default tag, but can be renamed.

To rename a schedule, double-click the tag to be renamed.

e ﬁeld becomes editable.

Enter the new schedule name. Up to 10 individually named Maintenance Schedules can be

created.

 17

ConguringandEditingMaintenanceSchedules

To conﬁgure a schedule, click the name of the schedule to be conﬁgured.

en choose from the following options to conﬁgure the Maintenance Schedule:

• To turn the Maintenance Period on, click the Activate Maintenance Schedule option.

• From the Day drop-down menu, select a day of the week when the schedule will occur.

• Use the From and To ﬁelds to enter the period of time that the Maintenance will occur.

• Select the Once Only checkbox to create a one-time only schedule; if this checkbox is not selected,

the schedule recurs on a weekly basis.

• Select Install Apple Soware Updates to install any available Apple Soware Updates.

• Select Lock Out User to prevent a user from accessing the computer during the Maintenance Period.

• Select Warn User At to provide a message to users warning them that the computer will be taken

over at a speciﬁed time, and enter the warning time in the ﬁeld provided.

• Use the Message for User text box to enter a custom message for the user, explaining that the

Maintenance Schedule will take place at a speciﬁed time; by inserting %d as a variable into the

message, Deep Freeze will automatically display the number of minutes until the Maintenance

Period begins. (Again, %d is a variable corresponding to the number of minutes between the

current time and the time that scheduled Maintenance will begin.)

• Select Shutdown Aer Maintenance to shut the computer down aer the Maintenance Period is complete.

e minimum time allowed for a Maintenance Period is 10 minutes.

To save any changes made, click Apply; the changes take eﬀect aer a restart.

18

MappingTab

e Mapping tab is used to map the user’s home folder to a speciﬁc awSpace or partition, or to map

elements of a user’s home folder to a speciﬁc awSpace or partition. is feature is only available at

the administrator level. e current logged in user can not be mapped.

To map a user’s home folder to a target destination, select the user’s account and under User Location

select one of the options available: Boot Volume, User awSpace, Partition, or Custom.

Boot Volume

is option maps the user account to the volume the operating system is booted

from.

User awSpace

is option maps the user account to the corresponding User awSpace created

for this user. It is not recommended that User awSpaces be renamed because a

renamed awSpace will prevent access from the original user account.

Partition

e user account can be mapped to a speciﬁc partition listed in the Drives tab.

Custom is option lets certain elements (pictures, movies and, music, etc.) of a user

account be mapped to the User awSpace/Partitions. To do this, click on

the element and select the awSpace/Partition that it will be mapped to.

Custom mapped users must be located on the boot volume. Users can not

be mapped entirely to their User awSpace/any other volume and then

partially custom mapped to another location.

For bookmarks, the location must exist to be mapped; e.g. if a user has never

run Safari, it can not be mapped. Deep Freeze does not create the folders and

bookmarks for a user.

If an attempt to map to a location with insuﬃcient space is made, the mapping action

will not take place.

e Short Name must match the Home Directory name in System Preferences >

Accounts > Account_Name > Advanced Options for mapping to work.

 19

DFUsersTab

e DF Users tab allows administrators to manage the Deep Freeze users present on a computer. ere

are a maximum of four users permitted on each computer, but only the ﬁrst user (the admin user) can

create, edit, and delete other DF Users.

Adding,Deleting,andEditingDFUsers

To add a new user, complete the following steps:

1. Click Add. A properties dialog appears, as shown.

2. Enter the DF User Name and Password and verify the password.

NOTE: If Apple Remote Desktop (ARD) is going to be used to manage Deep Freeze Mac

deployments, ensure that only alpha-numeric characters are used in the password or the

remote tasks will fail.

3. Click OK to save the changes to the user proﬁle, or click Cancel to exit with no changes

saved.

To delete a DF User, click Delete. A dialog appears asking for conﬁrmation of the deletion. Click Cancel

to exit the dialog, or click Delete to delete the DF User permanently. ere must always be at least one

DF User present; the ﬁrst DF User created can not be deleted.

To edit the properties of a DF User, click Edit. Edit the User Name and Password in the properties

dialog as needed.

20

UninstallTab

A computer must be in a awed state for the Uninstall option to be available. If the computer is in

a Frozen state, the Uninstall option is not available. If there are existing awSpaces on a computer,

choose either to retain or delete them by selecting the preferred button.

If the option to retain awSpaces is chosen, all existing awSpaces are moved to the boot volume (/

Volumes/username.dmg). To access the boot volume, launch the Terminal and change the directory to

the boot volume /Volumes/username.dmg. awSpaces must be mounted manually by double-clicking

the icon.

To uninstall Deep Freeze, click Uninstall.

e computer restarts and Deep Freeze is uninstalled.

All program components are permanently deleted when Deep Freeze is uninstalled.

Before removing a awSpace, remove its proﬁle or folder mapping.

ExportingandImportingCongurations

A ﬁle containing the conﬁguration information set in the Deep Freeze Controller can be exported as a

property list ﬁle. e property list can be imported into another Deep Freeze Controller and deployed

to targeted computers.

To export the conﬁgurations set in the Deep Freeze Controller, click Export and save the ﬁle to a

preferred location.

To import a conﬁguration ﬁle, click Import and browse to the location of the saved ﬁle. e computer
