.h1;General Information

.h2;Startup
 User Guide, p. 2-4

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.

.h2;Startup and the 3+ Prep File
 User Guide, p. 2-4

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.

.h2;AppleTalk Active
User Guide, p. 2-6

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.

.h2;Login and Domains
 User Guide, p. 2-7

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.

.h2;Switching Between AppleTalk and Ethernet Cabling
 User Guide, p. 2-7

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.

.h2;Logging In With 3+Admin
User Guide, p. 2-8

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.

.h2;Creating or Changing the Startup Configuration
User Guide, p. 2-18

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.

.h2;Shutting Down Your Macintosh
User Guide, p. 2-23

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.

.h2;Using 3+Print
User Guide, p. 3-1

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.

.h2;Rebuilding the Desktop on a Shared Folder
User Guide 4-1

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).

.h2;Write/Create Shared Folders
User Guide 4-14

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.

.h2;Keyboard Equivalents
For 3+ for Macintosh version 1.2.1, the keyboard equivalents
are as follows:

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

Status Dialog
Save as startup Command-S

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


.h2;User Guide Appendix A
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
User Guide 4-7

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).

User Guide, p. 4-13

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.  Application

.h1;Compatibility Information

WriteNow

Version 1.0 of WriteNow will not work reliably when opened in a
3+ Shared Folder.  Use a later version.

ResEdit
 User Guide, p.1-6

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.

AppleShare and 3+ for Macintosh
 User Guide, p. 2-16

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.

Cricket Draw
 User Guide, p. 3-2

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.

PageMaker

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.

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.

MacWrite

 User Guide, pps. 4-18, 4-19
 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

User Guide, Appendix D

 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.

User Guide, Appendix D

 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
command 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.

NetSwitch 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.

.h2;NetSwitch MF

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.

.h2;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.
