.H1;General Information

.BR;Startup
.BR;User Guide, p. 2-4
.BR;If your Macintosh netstation beeps during startup it indicates that 3+
for Macintosh installation has failed.  The 3+ icon in the Welcome to
Macintosh box will be displayed with an X through it, indicating an
unsuccessful startup.

When you start up your Macintosh netstation with 3+ for Macintosh, be
sure not to hold down the 3 key (character key on the keyboard).
Holding down this key prevents  the 3+ for Macintosh system software
from loading, and you will not be able to log in.

.BR;Startup and the 3+ Prep File
.BR;User Guide, p. 2-4
.BR;If you start up your Macintosh with 3+ for Macintosh and receive error
messages that you are unsure of (for example; "name server not
responding", "Could not find name in Name service", etc.), first
confirm that your network connection is properly set up.  If you are
using someone else's startup disk or a copy of someone else's startup
disk, it is likely that the 3+Prep file on that disk is causing the
problem.  Remove it from your System Folder, and restart your
Macintosh.

.BR;AppleTalk Active
.BR;User Guide, p. 2-6
.BR;When using the 3+ network on AppleTalk, the Chooser must  indicate
that AppleTalk is Active at all times.  If you click Inactive, your
netstation will not be able to access the server.  If this occurs,
open the Chooser from the Apple menu, click the AppleTalk Active
button, and restart your Macintosh.  Restart your Macintosh to
reestablish the link between your netstation and the server.

.BR;Login and Domains
.BR;User Guide, p. 2-7
.BR;If a large number of domains exist on your network, not all of them
will be displayed in the domain menu in the Login box.  To log in as a
user in a domain that is not displayed, enter your user name and
domain in the Name box using a colon to separate them.  For example,
Jeff Mason:HQ.

.BR;Switching Between AppleTalk and Ethernet Cabling
.BR;User Guide, p. 2-7
.BR;To switch between using AppleTalk and Ethernet cabling, always log out
before changing the Control Panel setting.  Then restart your
Macintosh netstation.  Do not change the Control Panel network setting
without restarting your netstation if you are using 3+ for Macintosh.
Switching from Builtin (AppleTalk) to EtherTalk while still logged in
causes any 3+ connections to return a "Server not responding" error
message.

If you switch without logging out,  you may not be able to link to
your Home Folder or other private Shared Folders.  Contact your
network administrator to unlink you from all servers to which you may
have been connected.

.BR;Logging In With 3+Admin
.BR;User Guide, p. 2-8
.BR;You are now allowed to log in after opening the 3+Admin application If
you are not logged in when you open 3+ Admin, the Login dialog box is
displayed to allow you to log in.  Clicking the Cancel button returns
you to the Finder.

.BR;Creating or Changing the Startup Configuration
.BR;User Guide, p. 2-18
.BR;To create or change the startup configuration, open the Chooser, log
into the network, link to the desired Shared Folders or printers,
click Status in the 3+ Network Window, click Save as Startup, and
click OK.  To delete the startup configuration,
open the System Folder and drag the 3+ Prep file into the trash can.
To disable 3+ Prep when restarting your Macintosh, simply hold the
mouse button down after Welcome to Macintosh is displayed.

.BR;Shutting Down Your Macintosh
.BR;User Guide, p. 2-23
.BR;Choose Shutdown before turning off your Macintosh netstation.  The
recommended procedure is to save your latest work, quit your
application, and choose Shutdown or Restart from the Special menu in
the Finder.  Shutdown unlinks all network objects, logs you out of the
network, and ejects any diskettes in the netstation drives.

.BR;Using 3+Print
.BR;User Guide, p. 3-1
.BR;When you hold down the Option key when selecting 3+Print from the
Chooser, only the currently linked printer will be displayed within
the Chooser list.  This happens almost immediately, removing the delay
which can otherwise occur while the 3+ for Macintosh software polls
all of the servers in the user's domain for printers.

.BR;Rebuilding the Desktop on a Shared Folder
.BR;User Guide 4-1
.BR;If for any reason you decide to rebuild your desktop on a network
Shared Folder (by holding down the Command and Option keys when
starting up or returning to the Finder), do so from the Home Folder
level or another first level shared directory (such
as 3Plus or APPS if shared by the server-user).

.BR;Write/Create Shared Folders
.BR;User Guide 4-14
.BR;Macintosh netstation users linked to Shared Folders with Write/Create
access rights can copy files to the Shared Folder, but not see them.
IBM PC or compatible netstation users can use the DIR command to see
the names of all files in a directory with Write/Create access rights,
but cannot read them.

.BR;Keyboard Equivalents
.BR;For 3+ for Macintosh version 1.2.1, the keyboard equivalents are as
follows:

.BR;3+ Network Window
.BR;Status  Command-S
.BR;Options Command-O
.BR;Getinfo Command-G
.BR;Up a level Command-Up Arrow
.BR;Down a level Command-Down Arrow

.BR;Status Dialog
.BR;Save as startup Command-S

.BR;Getinfo User/Server/Shared Folder in 3+File
.BR;New password Command-N
.BR;Delete password Command-D (functional only in Getinfo User and Server)

.BR;User Guide Appendix A
.BR;The message

 "server:domain:organization" is not
 responding.  Retrying...

indicates that the server is not responding to requests.  3+ will
continue trying to establish communication with the server unless you
cancel by pressing Command-. (period).  Cancelling the operation
breaks all connections to the indicated 3+Share server.  If you
cancel, restart your Macintosh and log in before continuing work.

NOTE: Wait at least one full minute before pressing Command-.
(period).

.H1;File System Information

.BR;User Guide 4-7
.BR;A Macintosh user will be unable to create or move a folder into
another folder if the full pathname of any folder or file exceeds a
92 character pathname limit.  This still permits a fairly deep folder
environment  (approximately 9 levels deep with large folder names).
If shorter names are used, still greater depth is possible (subsequent
renaming may be prevented if the 92 character pathname limit is
exceeded).  Attempting to exceed this limit results in the Finder
displaying messages indicating a disk error or an unknown error.

If you share directories that are deep within an existing folder
hierarchy, the maximum depth of any newly Shared Folder is restricted
because of the pathname length limit (pathnames from the root
directory).

.BR;User Guide, p. 4-13
.BR;Shared Folders, or folders that contain Shared Folders, should not be
renamed or moved.  Users linking to a Shared Folder that has been
renamed or moved will be unable to access the files and may receive an
error message.  If you want to change the name of a Shared Folder,
unshare the folder first, then reshare it with a new name.  If you
want to move a Shared Folder to another location, unshare it first,
move the folder, then reshare it.

A folder can be assigned more than one Shared Folder name.  It is not
advisable, however, for a user to link through two different Shared
Folder names to the same folder.  Doing so may lead to the accidental
deletion of files.  Both Shared Folder names actually represent the
same information on the server's disk.

When attempting to copy a file from one to the other, data will be
lost.  The Finder will present a message asking if the user wants to
replace the existing file in the destination folder with the new one.
Since these two files are actually one with the same name, the Finder
is trying to replace that file with itself.

When the user clicks Yes, the Finder deletes the file from the
destination folder before it attempts to copy the file from the source
folder.  As a result the file is mistakenly deleted before it can be
copied, and its data will be lost.

.H1;Application Compatibility Information
.BR;WriteNow
.BR;Version 1.0 of WriteNow will not work reliably when opened in a 3+
Shared Folder.  Use a later version.

.BR;ResEdit
.BR;User Guide, p.1-6
.BR;The developer's tool ResEdit (version 1.0) is limited to work only on
files in the root level (the window that opens when you double-click
on the Shared Folder icon on the desktop) of 3+ Shared Folders.  To
use ResEdit on a file outside of the root level, first move the file
to the root level.

.BR;AppleShare and 3+ for Macintosh
.BR;User Guide, p. 2-16
.BR;To use AppleShare and 3+ for Macintosh from the same diskette or hard
disk, start with an AppleShare boot diskette (because AppleShare
modifies the System file).  Copy 3+ File, 3+ Print, and 3+ Icon Giver
from the System Folder of your 3+Share User for Macintosh  diskette to
the System Folder of your AppleShare diskette.

.BR;Cricket Draw
.BR;User Guide, p. 3-2
.BR;To print using the Cricket Draw application version 1.0, you must
rename the 3+ Print file in your System Folder to LaserWriter.
Cricket Draw 1.0 only sends files in a PostScript format when the 3+
Print file is named LaserWriter.  Renaming 3+ Print will not affect
any other 3+ for Macintosh network operations.  The Chooser will still
show the 3+ Print icon, but it will be named LaserWriter.

.BR;PageMaker
.BR;PageMaker version 3.0 cannot be installed directly onto the network.
To install version 3.0, you must first install onto a local hard disk.
Then log into the network, link to a Shared Folder, and copy the
PageMaker files from the hard disk to the network.  For further
information, contact your network reseller for information on updates
to the PageMaker software.

.BR;User Guide, p. 3-6
.BR;When printing from PageMaker version 2.0 or 3.0, you must use the
Apple LaserWriter driver or download Aldus Prep temporarily.
Permanently downloading the Aldus Prep file causes the LaserWriter to
run out of memory very quickly.  To download Aldus
Prep temporarily, open the PageMaker Print dialog box, hold down the
Option key, and click Print.  Click the Make Aldus Prep permanent
checkbox to remove the X.  Then send the document to be printed.  For
complete information on this PageMaker option, see "Using PostScript
Options" in your PageMaker manual.  Only PageMaker versions 2.0 and
later are supported in 3+ for Macintosh.

.BR;MacWrite
.BR;User Guide, pps. 4-18, 4-19
.BR;Only MacWrite version 4.6 or later is supported.

Using XCOPY or any other DOS copy/move utility programs to copy or
move Macintosh files and directories is not supported in 3+ for
Macintosh 1.2.1 and WILL NOT work correctly.  DOS utilities programs
cannot properly accommodate the MacFS support information that is
associated with these files or folders.  Users or network
administrators must use the Finder on the Macintosh for copying or
moving Macintosh files and directories.

.H1;IBM PC Netstation Information
.BR;User Guide, Appendix D
.BR;Because of the way pathnames to server directories and files are
managed in Share (DOS), there is a limitation on the depth of a folder
hierarchy in terms of a maximum DOS pathname length.  The current
limit is set at 92 characters and includes the drive ID ("c:\x\y" is 6
characters long).  Folders created on a Macintosh that have names that
are not legal DOS names will always have DOS names 8 characters in
length or less.

.BR;User Guide, Appendix D
.BR;Renaming folders is not permitted if the length of any folder or file
pathname will result in a violation of the 92 character pathname
limit.

IBM PC and compatible netstations users should know that the
file/folder name length of the DOS directory listing being displayed
as 0 (zero) is valid for applications and some types of documents when
doing a DIR listing.  The DOS DIR directory comm and can display the
file/folder name length as 0 (zero), but users should be cautioned
against deleting this file without  first using the MACDIR command.

This is due to the differences between the DOS and the Macintosh File
Systems.  A zero length file may be an empty data fork for a
Macintosh file.  Use the MACDIR command to verify the full
file/folder name. MACDIR will display a directory somewhat similar to
a DOS directory listing, but with Macintosh file system information
added.  The full name of the file/folder within the Macintosh file
system can consist of up to 31 characters, some of which are illegal
in DOS names, such as spaces.  File naming, therefore, will not
necessarily look the same.  If you are unsure about the status of a
file seen in a DOS DIR listing, use the MACDIR listing before deleting
anything.

.H1;3+Route and 3+NetConnect Support
In this release, Macintosh netstations are not  able to use 3+Route to
access Shared Folders and printers on remote servers via modem and
telephone line connections.  IBM PC and compatible users can to use
3+Route to send and receive messages with 3+Mail.  Full 3+Route
support for Macintosh netstation users will be included in a future
release.

.H1;Switch Launching

This section briefly describes switch launching.  Switch launching
allows you to switch from using the System Folder on your Startup
diskette to using a System Folder in another location.

This release of 3+ for Macintosh provides a way to automatically
switch launch to your network Home Folder when you start up your
Macintosh netstation, and at that time eject your Startup diskette.

One advantage of switch launching, either manually or automatically,
is that once your Startup diskette is ejected you can insert other
diskettes without constantly having to swap back and forth.  Another
advantage is the ability to add any desired fonts or desk accessories
to your System file.  Since you can have a System Folder on the
network server, you do not have to worry about available space on an
800K diskette.

NOTE:  You can only switch launch to your Home Folder.  Switch
launching to other Shared Folders is not permitted.  This prevents two
users from switching to the same System Folder.

Make sure that the latest versions of 3+ for Macintosh and Apple
system software are present in the Home Folder's System Folder.  When
you try to print after switch launching, for example, you will get an
error message if you do not have 3+Print in the Home Folder's System
Folder.

1. Start up your Macintosh netstation using your 3+ for Macintosh
Startup diskette.

2. Log in and link to your Home Folder and any other Shared Folders or
printers desired.

3. Copy the System Folder from your 3+ for Macintosh Startup diskette
into your Home Folder.

4. Switch launch to your Home Folder.

You can switch launch using any one of these methods:

Open any application resident in your Home Folder.

Hold down both the Command and Option keys and double click on either
the Finder or MultiFinder in your Home Folder's System Folder.

Use NetSwitch or NetSwitch MF as described in the following sections.

NOTE:  Make sure your Startup diskette is not set to use MultiFinder.
Apple System software does not support switch launching to another
diskette or folder if you are currently using MultiFinder.  When you
switch launch you can use MultiFinder from your Home Folder, but you
must still set the Startup diskette to use Finder at startup.

.BR;NetSwitch
.BR;NetSwitch is a utility that allows automatic switch launching to your
Home Folder each time you start up your Macintosh netstation.  The
advantage of using this utility is the elimination of confusion about
which System file you are using.  NetSwitch opens the Finder on the
network.  If you want to use MultiFinder, refer to the NetSwitch MF
section.  If you do not have the NetSwitch application on your
diskette, contact your network administrator.

1. Start up your Macintosh netstation using your 3+ for Macintosh
Startup diskette.

2. Log in and link to your Home Folder and any other Shared Folders or
printers desired.

3. Using the 3+ Network Window, save your startup settings from the
Status dialog box to create a 3+Prep file on your Startup diskette.

4. Make sure you have a System Folder in your Home Folder.

Copy the System Folder from your Startup diskette, if necessary.

5. From the Finder, click on the NetSwitch icon.

6. Choose Set Startup... from the Special Menu.

7. Select Finder at the top of the dialog box; select NetSwitch from
the bottom of the dialog box; click OK.


CAUTION:  At the top of the dialog box, be sure to select Finder, not
MultiFinder, and at the bottom of the box, select NetSwitch.

8. Restart your Macintosh netstation.

You are automatically switch launched to the Finder on the network,
and your Startup diskette is ejected.

NOTE:  If you attempt to log out or unlink the Home Folder after
switch launching to it, a message appears indicating you should shut
down or switch launch to another diskette before taking this action.

The Save Startup check box in the Status dialog box is disabled after
switch launching.  If you want to change your Startup configuration,
refer to "Changing Startup Settings after Switch Launching" later in
this section.

.BR;NetSwitch MF
.BR;NetSwitch MF operates the same way as NetSwitch, except that it
automatically runs MultiFinder instead of Finder from your Home
Folder.  The MF in NetSwitch MF stands for MultiFinder.

1. Perform steps 1 through 4 from the previous section.

2. From the Finder, click on the NetSwitch MF icon.

3. Choose Set Startup... from the Special menu.


4. Select Finder at the top of the dialog box; select NetSwitch MF
from the bottom of the dialog box; click OK.

CAUTION:  At the top of the dialog box, be sure to select Finder, not
MultiFinder, and at the bottom of the box, select NetSwitch MF.

NOTE:  If you attempt to log out or unlink the Home Folder after
switch launching it, a message appears indicating that you should shut
down or switch launch to another diskette before taking this action.

The Save Startup check box in the Status dialog box is disabled after
switch launching.  If you want to change your Startup configuration,
refer to "Changing Startup Settings after Switch Launching" on the
next page.

Changing Startup Settings after Switch Launching
You can change your default 3+ for Macintosh startup settings when
using NetSwitch or NetSwitch MF.

To change your current 3+ for Macintosh startup settings:

1. Start up your Macintosh using your 3+ for Macintosh Startup
diskette.

If you followed the switch launch procedures in the previous section,
you are automatically switch launched and the Startup diskette is
ejected.

2. Insert the Startup diskette into the disk drive.

If you did not use NetSwitch or NetSwitch MF, the Startup diskette
will still be in the drive.

3. From the Finder, click on the Startup diskette icon.

4. Choose Set Startup... from the Special menu.

5. Select Finder at the top of the dialog box; select Finder Only from
the bottom of the dialog box; click OK.

CAUTION:  At the top of the dialog box, be sure to select Finder, not
MultiFinder, and at the bottom of the box, select Finder Only.

6. Restart your Macintosh netstation.

7. Select Chooser from the Apple menu.

8. Click 3+File.

If you are already logged in, click Network.  If not, log in and link
to your Home Folder and any other Shared Folders or printers desired.

NOTE:  If you unlink your Home Folder, you will note be able to switch
launch.

8. Using the 3+ Network Window, save your startup settings from the
Status dialog box to create a 3+Prep file on your Startup diskette.

9. From the Finder, click the NetSwitch (or NetSwitchMF) icon.

10. Select Set Startup... from the Special menu.

11. Select Finder at the top of the dialog box; select NetSwitch from
the bottom of the dialog box; click OK.

CAUTION:  At the top of the dialog box, be sure to select Finder, not
MultiFinder, and at the bottom of the box, select NetSwitch (or
NetSwitch MF).

Every time you start your Macintosh netstation, the 3+ for Macintosh
Startup settings saved in this procedure are in effect.
