Changes with the Macintosh System 7.5 Update 1.0


MORE INFORMATION

General Information About the Update

System 7.5 Update 2.0 provides the enhancements introduced in System 7.5 Update 1.0, plus many more.

This update installs the latest versions of all components (including any components that were disabled using the Extensions Manager) it finds on the disk it is updating. After running the Installer, the updated components will be in the same folders as they were before installing the update. For example, new versions of disabled extensions will be in the "Extensions (Disabled)" folder, and new versions of disabled control panels will be in the "Control Panels (Disabled)" folder.

The file called "System 7.5 Update" replaces the enabler on all computers capable of running system software versions 7.5 and/or 7.5.1. Computers that did not previously need an enabler to work with system software versions 7.5 and 7.5.1 still need the System 7.5 Update file, since it contains most of the fixes delivered in this update.

The file called "System 7.5.2 Update" replaces the enabler file on all computers capable of running system software version 7.5.2.

This update includes all of the fixes included with the previously released 7.5.2 Printing Update, the PowerBook 5300 System Software Update, and the PowerBook 2300c Update. These updates are not needed if System 7.5 Update 2.0 is installed. If any of these have been installed, System 7.5 Update 2.0 should still be installed, since it contains additional fixes.

After installing the update, the About This Macintosh window says "System Software 7.5.3." The window also says "System 7.5Update 2.0," to indicate the source of the system software.

Changes to the Finder

This update includes a new version of the Finder with the following changes:

When rebuiliding the desktop, comments typed in a file's Get Info window are no longer deleted. (Of course, if you delete the desktop database for example, by making it visible using a utility and then moving it to the Trash, the comments will be lost because the Finder will have to build a new desktop at startup.)

The Name field (used in Finder windows set to one of the list views) is wider, allowing more characters to be seen in the filenames.

On PowerPC-based computers, icons are translucent when dragged (rather than simply appearing as outlines). When dragging several icons at once, only the icon under the mouse will be translucent,the others will still be outlines.

Copying large numbers of small files is faster. (Previous versions of the Finder updated the bar in the copy progress dialog box approximately thirty times per second; the new version updates the copy progress bar far less frequently.)

The Finder Update file (once named PowerPC Finder Update) is now part of the Finder. This update deletes all old versions of this file.

When the Clipboard is active, the Clean Up Window command is dimmed. This eliminates a crashing bug in the Finder.

The Finder flushes the processor's cache more intelligently, improving the Finder speed on all 68040- and PowerPC-based computers.

Fixes a problem that caused an out-of-memory error when emptying the Trash if QuickDraw GX was installed.

Fixes a problem that caused seemingly false out-of-memory messages when trying to open or close Finder windows. This problem sometimes occurred when the desktop had very few icons on it, a window with the Kind column was visible, and a large number of different kinds of documents had been displayed since the last restart.

Fixes a problem introduced by the Finder that shipped with System 7.5 Update 1.0. The Find window of Find File will now be made active if Find File is already open and the Find option is chosen from File menu (or Find File from the Apple menu).

If you are trying to connect to your computer and your server password has expired or needs to be changed when you try to use an alias to connect to the server, you'll see a message that the password needs to be changed. (Prior versions told the user that the server couldn't be found.)

File copies are now done asynchronously, which makes the CPU more available to other applications during copying. If another application is made active during a file copy, the computer does not slow down as much. This effect is most noticeable when using Apple Remote Access.

Finder window titles are now erased before they are overwritten. (Previous versions rendered window titles unreadable in some circumstances.)

Changes to Find File

The following are the changes in Find File 1.1.2:

Changes to Standard File

Fixes an occasional crash in Standard File that occurred when the data cache was not flushed before being disabled.

Fixes a memory leak with some of the dialog boxes used for opening and saving documents in Standard File.

Fixes a problem in the dialog box used for opening files that could allow the pop-up menu to be dimmed in Standard File.

Changes to Control Panels

PowerPC-based computers with PCI slots now use the Monitors & Sound control panel, instead of the Sound & Displays control panel, to control monitor and sound settings. (System Update 2.0 removes Sound & Displays.) You can do a custom installation to install the Sound control panel if you need it for older applications. (The Monitors & Sound control panel works only on PCI-based computers.)

The Memory control panel now displays "Will be off after restart" if Virtual Memory is turned off, as a reminder that just turning Virtual Memory off does not fully deactivate it.

The Memory control panel now uses a larger default setting for the Disk Cache. After you install this update, the new setting will be used only if the Use Defaults button in the Memory control panel is clicked. The new default is 32K for each megabyte of physical RAM installed, up to a maximum of 4096K. (Virtual RAM is ignored for this calculation.) Thus, a computer with 16MB of physical RAM would use 512K for its default disk cache size, resulting in better performance for disk-intensive tasks than the original default of 96K.

Fixes a bug in resizing a RAM disk in the Memory control panel while File Sharing is on.

Fixes a problem in General Controls panel that caused problems with Retrospect Remote if either application or System Folder protection was turned on.

Includes a new option in the General Controls panel: "Folder that is set by the application." Clicking this option sets the default folder to the folder containing the document being opened. Thus, when you open a document by double-clicking its icon, the default folder will be set to the folder containing the document (instead of to the Documents folder or to the folder containing the application that opened that document).

Fixes a problem in General Controls panel that could hang the computer if Applications folder protection was turned on and there was a document or alias named "Applications" at the root level of the startup disk.

Fixes a problem in the General Controls panel's folder- protection code that could cause folders to become invisible if Stuffit Spacesaver was installed.

CloseView no longer uses key combinations that were already used by the Finder. The new key combinations for CloseView are:

If CloseView is active, it remains active after you change your monitor's bit depth.

CloseView no longer hangs the system if Balloon Help is on and an audio CD is inserted.

Includes the following new international keyboard layouts:

Installs the updated versions of the following international keyboard layouts if older versions are already installed:

Changes to Apple Guide

This update includes Macintosh Guide 1.3 (and several new Guide Additions files), which provides updated onscreen help for system software.

This update includes Apple Guide version 2.0.2, which includes the following improvements:

Changes to Apple Menu Options

Includes Apple Menu Options v.1.1.2, which introduces the following changes:
