[These are the developer release notes from s2 through s8. These release notes are of historical interest only.]
The following is a partial list of changes between System 7.5 Update 2.0 and System 7.5 Update 1.0. System 7.5 Update 2.0 brings some components from System 7.5.2 to other Macintosh computers, as well as providing bug fixes and enhancements (System 7.5.2 ships on the PCI-based Macintosh computers. You can not install System 7.5 Update 2.0 on Macs which use System 7.5.2.) System 7.5 Update 2.0 supports all Macintosh computers since the Macintosh Plus which do not need System 7.5.2. This release does not have all of the features which will be in the final shipping release. Please note that some of the components still under development may not make our release schedule and earlier versions may be used. We will document additional features as they are added to this system update. System 7.5 Update 2.0 is a superset of System 7.5 Update 1.0.
This document is the prototype for what will eventually be the technical note describing Macintosh System 7.5 Update 2.0. Your feedback is needed to help make this a better document. Send document feedback to DEVSUPPORT (devsupport@applelink.apple.com) with a subject line including the words "SU2.0 TN". This will help us process your feedback faster.
Please send bug reports to DEVSUPPORT (devsupport@applelink.apple.com) or APPLE.BUGS using the bug reporter stack found on just about every developer CD.
s8 Changes
Finder
The Finder now preserves info window comments across desktop rebuilds. (The dialog box for rebuilding the desktop will change; this is not the final message. Please be sure and test this feature; it was a large change in the Finder.)
The Finder now uses translucent drag manager calls when dragging on PowerMac computers. (Developer documentation on the translucent drag manager is still pending.)
Note that the Finder "Special" menu has a different title; this isused to point out that this Finder is not final and should be used for testing only.
Large Volume Support
At this point, due to schedule pressure, we may not be able to add large volume support for all Macs. This means that only those machines which currently have large volume support in ROM will support volumes greater than 4GB. (Macintoshes which run 7.5.2)

dialog to prompt the user when seeing this dialog.
System 7.5 Update Changes
• Added InterfaceLib from System 7.5 GM to fix problem with Native Resource Manager.
• removed keyboard resources from the enabler since they are already in the system file.
Known Problems
• Do NOT use s4 on a Powerbook 100 or MacPlus. The computer will crash during startup with an unimplemented trap. The LC 580, LC 635, and Performa 635 should work ok now.
• HD SC Setup 7.3.5 will crash if you try to initialize the startup volume or RAM Disk.
Faster file transfers with all AppleShare servers, including File Sharing.

Removed Components
Due to their disk size, updated versions of the following are not in System 7.5 Update 2.0 s3. PowerTalk and QuickDraw GX will be on the CD-ROM and optionally in the floppy disk set.
• PowerTalk (AppleMail, Catalogs Extension, DigiSign Utility, Direct Dialup and Mailbox Extension)
• QuickDraw™ GX
• QuickTime™ and QuickTime™ PowerPlug
System 7.5 Update Changes
• New DRVR -16499 (Sound Input Driver)
• Macintosh computers with PowerMac Upgrade Cards could get a trashed system heap during startup.
• In s2, trying to add alert sounds in the Sound control panel hangs some Macintosh computers.
• A Process Manager internal call that was not implemented on Macintosh Plus, SE, Portable, II, IIx, IIcx and SE/30 computers now is.
• Added new international keyboard resources to add "ISO Spanish" and "Canadian-CSA" keyboard support.
• New Sound In DITL for Q9x0 fixes having reversed External Line and Internal CD buttons.
• Updated Thread Manager (gpch 669) to fix some Thread Mgr internal utility routines calling conventions.
• Fixed MacOS™ splash screen drawing code which wasn't ensuring Color Quickdraw is available before using it.
Known Problems
• Do NOT use s3 on an LC 580, LC 635, or Performa 635. The computer will crash with an address error just before extensions start to load.
• Do NOT use s3 on a Powerbook 100. The computer will crash during startup with an unimplemented trap.
• There will be an alert during startup upon reaching Finder which states "The system extension 'Finder Scripting Extension' could not be used because it is too old". This is because s3 has Finder 7.5.3 but no updates of components which are tied to the Finder version. This also means PowerTalk will not work. A new version of PowerTalk and the Finder Scripting Extension will be posted as soon as possible.
• HD SC Setup 7.3.5 will crash if you try to initialize the startup volume or RAM Disk.
• When booting an LC 5200 a message stating that the system enabler is damaged will be displayed. This message comes up because the LC 5200 system does not have the InterfaceLib that the Native Resource Manager is looking for.
NOTE: Version s1 was not generally seeded. s2 was the first general seed of System 7.5 Update 2.0.
New Features
• Native Resource Manager
The 7.5.2 PowerPC version rebuilt to run on all prior Power Macintosh computers.
• Sound Manager 3.1
A fat implementation plus bug fixes.
• Display Manager 2.0
The version which shipped with 7.5.2 delivered here to run on the rest of the Macintosh family.
• Disk First Aid 7.2.2
Provides support for volumes larger than 4 GB.
• HD SC Setup 7.3.5
The latest version from Workgroup Server system software.
Changed Components
• Apple Guide extension 2.0d1
Version 2.0 will contain improvements to virtually all aspects of Apple Guide code to improve overall speed. Optimizations will be made to extension, background application code, and database I/O routines. No performance measurements are available at this time.
Previously versions of Apple Guide have a hard coded limitation of 8 guide files open at once. This includes the main guide file and 7 additions. The limitation is due to static arrays in the guide database code. This limitation will be removed by modifying database code to use dynamic arrays resulting in as many guide files open as can fit in available memory.
• Apple Menu Options control panel 1.0.2
Fixed problems with menus disappearing.
• AppleShare Workstation extension 3.6
A faster version of the AppleShare client. The speedup is from two major changes to the client software:
1. Read-Ahead and Write-Behind Caching. Workstation 3.6 now performs read-ahead and write-behind caching. This enhancement creates a double-buffered Finder that simultaneously writes to the local volume and reads from the remote volume and vice-versa. This parallelism greatly increases file copy performance by doing useful work while waiting for I/O operations to complete on either the local or the remote volume.
2. Desktop Database Caching. Caching was implemented in Workstation 3.6 for selected desktop database AFP requests, such as GetForkParms and GetFileDirParms. The cache is small and flushed frequently to prevent the information from becoming stale.
• CloseView 7.2.1d1
Changed the keyboard equivalents from [O,X,upArrorw,downArrow] to [K,X,+,-]. CloseView is now compatible with Display Manager 2.0.
• File Sharing Extension 7.6.2
Latest version from 7.5.2. This version fixes a hang when inserting a CD if any of several disk compression utilities are installed.
• FindFile 1.1.2d1
Added the ability to move invisible items (by making them visibile before the move). This feature was added to assure that users had a way to delete corrupted AppleShare PDS files and Desktop database files when instructed to do so by a technical support person. Note that files moved back from the trash will remain visible.
• General Controls control panel 7.5.6a1
The General Controls control panel can now be opened even if the machine was booted with extensions disabled. General Controls 7.5.5 (and earlier) incorrectly munged the ioResult returned by GetCatInfo - this caused problems with some network backup programs backing up volumes with folder protection on. General 7.5.6 will add option to allow the user to disable the Power off key functionality and decide whether the Shutdown dialog should auto-cancel after one minute.
Fixed a compatibility problem between the Protection feature and some disk compression utilities.
Fixed a problem where the Mac hangs at startup when an alias to an unmounted disk named "Applications" is present.
Fixed a problem where PBGetCatInfo was returning incorrect values other than noErr for valid calls.
• InputBackSupport 7.5.2
latest version
• Laserwriter 8 v8.3
latest version
• Memory control panel 7.5.4b3

System 7.5 Update Changes
• CalcMenuSize Patch
Added a patch to CalcMenuSize on 660av, 840av and Power Macintosh computers. The patch restores the MDEF handle state which was being left blindly unlocked by CalcMenuSize. This patch is already present on other Macintosh computers.
• CleanUpApplication patch for Macintosh computers except the 660av, 840av and Power Macintosh models.
Fixed a problem where system software CleanUpApplication patches were being blown away before loading inits. This affected the Thread Manager and Display Manager.
• Dialog Manager StdFilter Update
Fixed a problem where the Standard Filter failed to preserve register D3. This was never a problem on 660av, 840av and Power Macintosh computers.
• DisableDataCache
Installed the Quadra version of DisableDataCache on earlier machines to better support 040 accelerator boards.
• Display Mgr 2.0
The latest version of the Display Manager software which shipped with the Power Macintosh 9500.

brought the Native Resource Manager which shipped with the Power Macintosh 9500 back to first generation Power Macintosh computers.
• PACK 2 update - Disk Initialization Package
Invalid name dialog for DOS disk with 5 2-byte characters as name.
• Power Off Key update
Fixed a timing problem which resulted in a PowerBook 540c freezing if the powerkey was held down while coming out of sleep.
Added the ability to disable the shutdown dialog.
Code was added to autodismiss the shutdown alert. The code to use it would look like this:
#ifndef kPowerKey
#define kPowerKey 0x7F
#define kShutdownDlog 0x7E
#define kDissablePwKy (short) 0x6B
#define kEnablePwKy (short) 0x00
#define kNoDismiss 0x00
#define kOneSecond 0x70
#define kTenSeconds 0x400
#endif
typedef pascal OSErr (*PwrKeyProc)(short item, short action);
/* Dismiss the shutdown dialog in 112 Ticks (≈1 sec) */
theErr = (*pPwrKey)(kShutdownDlog,kOneSecond);
etc…
}
return;
}
• Process Mgr update
Fixed a problem where the Process Manager could trash memory at ioNamePtr^ on _Unmount calls
Fixed a check for TMON which was using an incorrect low memory accessor.
• ResolveIDConflicts fix
Fixed a problem where ResolveIDConflicts would miss a FONT/NFNT conflict in the main resource chain.
• ScrollBar CDEF Update
Fixed a problem where the ScrollBar CDEF was using an unlocked dereferenced handle across a memory moving call.
• Sound In Driver Update
Fixed a problem on Power Macintosh Upgrade card systems where the sound in driver and the sound manager did not agree on the size of a data structure (which could lead to heap corruption).
• Standard File Update
Fixed the following problems:
Memory leak with Standard File "Get" dialogs (10 byte region per list item drawn)
Standardfile causing blockmove from NIL
StandardFile calls NewControl with NIL pointer
DrawCell() in StandardFileLDEF.c uses deref'd handle after memory moves
Memory leak in StandardPutFile, SFPutFile
• Standard MBDF Update
The menu bar defproc (MBDF) uses a dereferenced handle after it may have moved.
• LC 5200 support
System 7.5 Update 2.0 now supports the LC 5200.
• WorkGroup Server Support
System 7.5 Update 2.0 supports all currently shipping Workgroup Servers.
Known Problems
• The Sound In Driver will hang a Quadra 900 or 950 when you try to add a sound using the Sound control panel.
• When booting an LC 5200 a message stating that the system enabler is damaged will be displayed. This message comes up because the LC 5200 system does not have the InterfaceLib that the Native Resource Manager is looking for.
