System Update 3.0 (800K floppy disk version)
IMPORTANT  This 800K disk version is only for those computers that cannot use
high-density disks: Macintosh II, Macintosh SE, and Macintosh Plus. It does not
install anything on other computers. This 800K version includes all the
necessary files for the above three models, but does not include all of the
files in the high-density version of this update. All other computers must use
the high-density version. (If your Macintosh II, Macintosh SE, and Macintosh
Plus has been upgraded to a 1.4 MB floppy disk drive, then you can use the 1.4
MB version of this update.)
What is System Update 3.0?
System Update 3.0 is a set of software enhancements that improves the
performance and reliability of Macintosh computers running system software
version 7.1, 7.1.1 (System 7 Pro), or 7.1.2 (for Power Macintosh).
System Update 3.0 provides the enhancements of System Update 2.0.1, Hardware
System Update 2.0, and Hardware System Update 1.0, plus additional
enhancements. (For a review of the System Update 2.0.1, Hardware System Update
2.0, and Hardware System Update 1.0 enhancements, see "What Other Enhancements
Does System Update 3.0 Provide?" at the end of this document.)
What are the enhancements that System Update 3.0 provides?
System Update 3.0 includes the following enhancements:
- Provides system-level improvements to increase overall system performance and
reliability on most Macintosh models.
- Corrects a problem that potentially allowed the system to become corrupted
during a power failure or a crash. This corruption would prevent the Macintosh
from restarting.
- Fixes a problem that prevented the Macintosh Plus from using any system
software newer than 7.1. Users wishing to upgrade to newer system software must
also delete the Finder Preferences file from the Preferences folder and
- Fixes the "About This Macintosh" box so the memory usage line does not get
drawn outside of the box's bounds.
- Prevents the potential file/media corruption that can happen when working
with a file that is on a remote volume and the connection to that volume is
lost. Now, when the remote volume is lost, its icon will remain dimmed on the
desktop (similar to what happens to the icon for a manually ejected floppy
disk). All attempts to open items on the lost volume will result in an access
privilege error. If you need to save your work on the open file, you will need
to use "Save As..." (or the equivalent) to save it to a different volume. In
order to re-connect with the lost volume, you will first need to close the file
you were working with, then drag the lost volume's dimmed icon to the Trash.
- Increases reliability for remote file saving when the client is running
System 7.1 or greater and the server is running a pre-7.0 system and using
pre-3.0 AppleShare.
-  Fixes a problem with throwing away folders that are on an AppleShare volume.
Sometimes when attempting to empty the Trash, the Finder would warn that the
folder contained items in use and could not be deleted. The Finder will now
properly delete such folders.
System Update 3.0 includes the following updates:
- Updates the Standard File package to include many fixes and enhancements. The
most significant fix corrects a crash problem when more than 20 volumes are
mounted. The most significant enhancement is the use of color icons.
-  Updates the Easy Access control panel to version 7.2. This new version
allows Sticky Keys to remain active after waking up if it was active when the
PowerBook or Portable went to sleep. Also, Easy Access now remembers whether
sticky keys, mouse keys, and slow keys were on or off between restarts.
-  Replaces TeachText with SimpleText version 1.0. Among other improvements,
SimpleText allows multiple documents to be open simultaneously, and allows
users to easily use a variety of fonts, font sizes, and font styles.
- Includes Apple HD SC Setup version 7.3.1,. This new version fixes a crash
problem version 7.3 has when run on Macintosh models that do not support
virtual memory.
- Updates the Memory control panel to version 7.3. This new version prevents a
potential crash during boot if the RAM disk was set too large. Also, this
control panel now opens with 32-bit addressing on.
Installing System Update 3.0
Before you install...
Do you have Macintosh system software version 7.1, 7.1.1, or 7.1.2?
You should install this update only if you have Macintosh system software
version 7.1, 7.1.1, or 7.1.2 installed on your computer.
If you have already installed earlier system updates, you should still install
System Update 3.0 in order to have the latest version of all system software.
System Update 3.0 provides additional functionality and fixes problems that the
earlier updates did not address.
Installation of System Update 3.0 includes three steps:
1.  Install the System Update
2.  Update your Apple utilities
3.  Update your Apple drivers
See the step-by-step instructions below.
Step 1:  Install the System Software Update
To install the system software update, follow these steps:
1. If you currently have the Connectix Enabler Patch on your hard disk, remove
it from your hard disk before proceeding with this installation.

3. Double-click the Installer icon.

all be dimmed if you select "Custom Remove" in the pop-up menu.
Step 2:  Update your Apple Utilities
The "Utilities ƒ" folder on the System Update 3.0 (800K) disk contains Apple HD
SC Setup version 7.3.1 and Apple Disk First Aid version 7.2. These updates are
intended to permanently replace the copies of Apple HD SC Setup and Apple Disk
First Aid on your System 7.1, 7.1.1, or 7.1.2 Disk Tools disk. This update is
recommended even if you have already installed System Update 2.0.1.
Follow these steps to update your utilities:
1.  Insert the System Update 3.0 (800K) in your floppy disk drive.
2.  Choose Eject Disk from the Special menu.
3.  Insert the Disk Tools disk in your floppy disk drive.
4.  Click the "Utilities ƒ" window to make it active.
5.  Drag the HD SC Setup and the Disk First Aid icons to the Disk Tools disk.
6.  When your Macintosh warns you that the files on your Disk Tools disk have

7.  Insert specific disks as requested until the files are fully copied.
8.  When you finish, continue with "Step 3:  Update Your Apple Drivers" below.
Step 3:  Update your Apple drivers
System Update 3.0 also contains a driver update for Apple hard disk drives. You
should install the driver update even if you have already installed System
Update 2.0.1. Follow the steps below to install the driver update on each Apple
hard disk drive you own:
1.  With your computer off, insert the Disk Tools disk in your floppy drive.
2.  Turn on your computer.
3.  Double-click the Disk Tools icon.
4.  Double-click the Disk First Aid icon in the Disk Tools window. (NOTE: If
you completed "Step 2: Update Your Apple Utilities" above, the Disk First Aid
utility on your Disk Tools disk should be version 7.2)
5.  Click the driver icon that corresponds to your Apple hard disk drive. If
you have more than one Apple hard disk drive, hold down the Shift key and click
each icon for the drives that you will be updating.
6.  Click the Repair button. Disk First Aid will now run some diagnostic tests
and make any necessary repairs on your drive. This may take a few minutes
depending on the size of your drive.
7. Open the File menu and choose Quit.
8.  Double-click the Apple HD SC Setup icon in the Disk Tools window. (NOTE:
For more information on Apple HD SC Setup, see your Macintosh user's guide. If
you completed "Step 2: Update Your Apple Utilities" above, the HD SC Setup
utility on your Disk Tools disk should be version 7.3.1)
