This Technote describes changes provided by
system software updates 10.0.1 through 10.0.4.
This Technical Note was created for application developers interested
in writing software that is compatible with Mac OS X. This list includes
changes that affect API level programming and product testing, it is not
intended to be an exhaustive list of all the changes in software updates.
[Jul 26 2001]
Software Update 1.3.1
Software Update provides a way to find and install the latest system software
for your computer by way of the Internet. Software Update Client 1.3.1 was provided
as a separate automated update.
- Software Update is now capable of resuming partial downloads
left over from broken connections (rr. 2482289, 2626156)
- A problem where Software Update would not proceed if the
administrator user had set up their login account with a blank
password has been corrected (r. 2664543)

Mac OS X version 10.0.1
General
This section describes changes provided in the 10.0.1 software update
that have not been categorized into separate sections.
- A problem where login by way of telnet for remote users could not be enabled in
the sharing control panel has been corrected (r. 2642204).
- A problem where the loginwindow application would crash after disconnecting a
secondary display and rebooting has been corrected. This problem would
only happen after a monitor was unplugged and if the Screen Saver "hot corners" had
been set while more than one monitor was connected (r. 2651694)
- As of 10.0.1, the 'allow remote login' check box only enables SSH and
no longer enables telnet, rlogin, or rsh (r. 2659900, 2680762).
|
Note:
Developers interested in to enabling telnet, rlogin, or rsh on their machine can follow
these steps:
- Launch Terminal
- Edit the file /etc/inetd.conf using your favorite UNIX-style text
editor (you need root privileges to edit this file). Or you can use
Mac OS X's TextEdit program to edit the file
using the following command in the terminal:
sudo /Applications/TextEdit.app/Contents/MacOS/TextEdit /etc/inetd.conf
- Find the lines that start with "#telnet", "#login" or "#shell" and remove
the # line comment character from the front of the one(s) you want to enable.
- Restart the machine or restart inetd services by entering the
following command line:
kill -HUP `cat /var/run/inetd.pid`
Be aware, though, these facilities do not provide encrypted connections
and so any data transmitted along these connections including passwords
and other information is not secure and may be viewed by others using
intrusive monitoring software and equipment.
|
- A problem where the Finder would not allow documents associated with classic
applications to be opened by double clicking them while their application was running
has been corrected (r. 2654742).
- A kernel panic that could occur when inserting CD into an external SCSI
CD/DVD drive has been fixed (r. 2593160).

for computers networked with AFP file servers.
- A problem where typing return would dismiss the volume selection dialog
when the OK button was unavailable has been corrected (r. 2613419).
- A problem where the Finder could hang when copying a large group
of files from an AFP server has been corrected (r. 2652633).
Back to top
ATSUI
Unicode is a character set which encodes the characters of many languages in a flat 16-bit
number space. Apple Type Services for Unicode Imaging (ATSUI) makes it possible for Mac OS
applications to draw Unicode text. ATSUI provides both low-level services for drawing Unicode
text as well as much of the high-end typographical control previously provided by QuickDraw GX.
- A problem where clicking the font popup menu in the font
panel could cause a crash when Japanese was selected as the
primary language has been corrected (r. 2651412).
- A problem where calling
DrawThemeMenu to draw
a menu item containing characters from the '.Keyboard' font
could cause a crash has been corrected (r. 2651752).
Back to top
Classic
The Classic environment is actually a full version of Mac OS 9.1
running in a protected memory space under Mac OS X. As a result,
most Mac OS 9 compatible applications will run side-by-side with
Mac OS X applications. This allows users to upgrade to Mac OS X
without fear of application incompatibility.
- A problem where the mouse cursor could disappear sometimes while Classic
was running has been corrected (r. 2650643).
Back to top
Kernel
The Kernel is the lowest level part of the operating system that mediates all access between
higher level system software services and the computer hardware.
- An error that could cause a kernel panic when unplugging FireWire hub
with many FireWire hard drives attached has been fixed (r. 2652891).
- A deadlock that could occur when calling
getattrlist has been
corrected (r. 2650684).
- A problem where some dual processor models would power down instead of
going to sleep after being idle for the sleep idle timeout period has
been corrected (r. 2653840).
Back to top
USB 1.8.1
Mac OS USB enables USB support for those Macintosh systems that have built in USB
hardware.
- A problem where HFS partitions could not be mounted on a third
party zip cd burner has been corrected (r. 2571027).
- Kernel Panics that could occur when hot-plugging or hot-unplugging some third party
USB devices have been corrected (rr. 2644892, 2653197, 2651246, 2650700,
2650292, 2653740, 2652598).
- A problem where some third party digital cameras could not be mounted
has been corrected (r. 2644893).
- A problem where
ReadPipeAsync 0x2000 from bulk
in pipe was reporting an incorrect value for the number of bytes actually
read has been corrected (r. 2647715).
- USB has been updated for compatibility with additional third
party USB modems (r. 2649923).
- A class definition for
IOUSBUserClientInit has been added to the
IOUSBUserClient.h header (r. 2659374).
- Calls to
DeviceRequest that did not request any returned data from
the device were not working correctly. Now they do (r. 2661216).
- Problems causing the failure of the majority of both calls to
ControlRequestAsync and calls to ControlRequest with a
buffer size larger than 4K have been corrected (r. 2664354).
- A problem where a kernel panic could occur when some third party USB serial
adaptors were in use has been fixed (r. 2657301).
Back to top
Mac OS X version 10.0.2
This section describes changes provided in the 10.0.2 software update
that have not been categorized into separate sections.
- Software update 10.0.1 installed a copy of the mach kernel in the
root directory without the invisible bit set rendering it visible in
Mac OS 9. Software update 10.0.2 correctly installs in invisible
version of this file (r. 2681213).
Back to top
Apple events
Apple events provide a simple interapplication and intraapplication
communications facility for Mac OS X applications.
- A crashing bug in the system's string-to-boolean coercion
handler has been corrected (r. 2647241).
Back to top
Apple File Server
The Apple File Server provides file sharing connectivity allowing other
Mac OS computers to connect and access files stored on your computer's
hard drive.
- A problem where AFP Server was not handling the
SIGABRT
message appropriately has been corrected (r. 2672862).
Back to top
Audio
This section lists changes to Mac OS X's Audio services. Audio services
provides APIs for playing back and recording digital sound samples in
a number of popular formats.
- A problem where sound could stop playing on some hardware during
interaction with some DMA disk drivers has been corrected (r. 2668216).
- USB Audio has been upgraded to support additional USB microphones (r. 2610501).
- New gain controls have been provided to resolve sound distortion problems
on some USB microphones (r. 2662841).
- Fixed a problem on some G3 models where sound was not being redirected
to the internal speaker after headphones were unplugged (r. 2643864).
- The Composite Video out port on dual USB iBooks is now functional (r. 2648943).
Back to top
Carbon
The Carbon API set provides human interface services for use in
applications programs. These facilities include the Window Manager,
the Control Manager, the Multilingual Text Editor, et cetera.
- Bevel buttons containing pictures were not being presented
on the screen correctly. The images were being drawn to an offscreen
buffer before being copied to the screen in a way that sometimes produced
unexpected results. This has been corrected (r. 2621061).
- A problem where the Unicode text edit control was not calling the
key filter routine for option-key characters or the tab character
has been corrected (r. 2657357, 2672865).
- A crashing that could occur after deleting a number of data ids from
a Data Browser control has been corrected (r. 2658469).
Back to top
Carbon Core
The Carbon Core incorporates essential services that are generally
devoid of a user interface. These facilities range from memory management
to process management.
- The routines
CSCopyUserName and CSCopyMachineName were
not incrementing the retain count for the CFString as implied by their names. As a result,
subsequent calls to CFRelease to release the returned string would decrement the return
count to zero and the string would be disposed of. This has been corrected and these
routines now increment the retain count as implied by their names (r. 2665708).
- Calls to
InstallExceptionHandler only affecting cooperative threads that
had already been created, however had no effect for any threads created after
it was called (as it should have). InstallExceptionHandler has been modified so that it
now applies to currently executing cooperative threads and all threads created after
it has been called (r. 2677122).
- As of System update 10.0.2, the value returned by
Gestalt for the
gestaltSystemVersion selector includes the system update number. For
system software 10.0.0 and system update 10.0.1, the system update number was not
included in the value returned by gestaltSystemVersion and the 10.0.0
value was returned (r. 2667654)
- A problem where information returned by
GetVolInfo calls made for Audio CDs
did not indicate that the disks were locked in the ioVAtrb has been corrected -
the ioVAtrb field is no longer set to zero when GetVolInfo is called
to retrieve information about Audio CDs (r. 2653440).
Back to top
Color
ColorSync provides system-level color management that enables
publishing software to achieve repeatable, reliable, and consistent
color on-screen, in print, and for electronic delivery.
- Problems with ColorSync matching that could produce unexpected
results with some third party raster printers have been corrected (r. 2658478).
Back to top
Disc Recording
The Disc Recording framework (introduced with update 10.0.2) includes
device drivers for recording CDs on machines with built in recordable CD drives
as well as a variety of the most popular 3rd party extenal USB and FireWire drives.
- iTunes for Mac OS X now supports CD Burning (r. 2650906).
Back to top
DrawSprocket
DrawSprocket provides drawing services coordinated with the display
manager that are useful in game development. This version of DrawSprocket
provides a number of corrections and fixes over previous versions.
- The DrawSprocket Switch/Queue mechanism was not working correctly. It has been
fixed (r. 2673855).
- The call
DSpFindBestContextOnDisplayID was not returning the optimal
Recommended Hz for the display. This has been corrected (r. 2664399).
- The
DSpContext_GetFrontBuffer was always returning a reference to the
main screen, even if the front draw sprocket context was set to a second
monitor (r. 2665075).
- The routine
DSpContext_SetCLUTEntries would clear the screen to a random
color when called to set up an 8 bit color look up table. DSpContext_SetCLUTEntries
has been corrected so that it no longer clears the screen (r. 2663971).
- Calls to
DSpContext_FadeGamma could leave the screen black
even if DSpContext_FadeGamma was called to fade the screen back
to normal. DSpContext_FadeGamma now works as expected (r. 2656253).
Back to top
Ethernet
Apple's ethernet software provides low level networking connectivity by
controlling Apple ethernet hardware supplied by Apple with Apple hardware.
- A problem where on some machines the ethernet hardware was not
being powered down during sleep (and thereby causing unwarranted battery
drain) has been corrected (r. 2674181).
Back to top
Finder
The Finder provides a graphical interface allowing the user to browse and
manipulate the file system.
- Problems where the Finder would not update a view of a folder after its contents
were changed was corrected (rr. 2666075, 2666045). Normally, the Finder will
update a window when the folder's modification date changes. This wasn't happening in
all cases, but now it happens every time.
- A problem where the Finder would crash when attempting to open a Internet Location File
in a window displayed in column view has been fixed (r. 2666098)
Back to top
FireWire
IOFireWireFamily.kext and related services provide Apple's
support for the IEEE 1394 High Performance Serial Bus standard.
- A problem where FireWire (FWIM and Drivers) would fail to load
on some hardware configurations has been corrected (r. 2666213)
Back to top
Graphics and Printing
The following describe changes in the drawing and rendering facilities provided
in Mac OS X.
- A problem where calling
PMSessionMakeOldPrintRecord with a
requested resolution would create an invalid PrintRecord has been corrected (r. 2656456).
Back to top
Kernel
The Kernel is the lowest level part of the operating system that mediates all access between
higher level system software services and the computer hardware.
sysctl calls attempting to list all of the kernel processes could
sometimes cause a Kernel panic. This no longer occurs (r. 2677729)
- NFS exporting an HFS file system was losing some files. This
was due to HFS not taking the "." and ".." entries in the remote
directory structures into account when calculating their size and
contents. This was fixed by having the vnode operations adjust their
offset positions by including the aformentioned entries in their
calculations (r. 2680605).
- Calling
getdirentries() (or using 'ls') in a system with an
xnu-133 kernel sometimes
returned duplicate entries possessing the same node number on HFS file systems.
This was caused because the
catalog position iterator was given an offset that was defined as the size of two
hfsdotentry structs. It was fixed by changing the offset to zero and supplying
variables that point to the VCB and FCB structures (r. 2682032).
- With JIS the keyboard device driver doesn't correctly identify the keyboard
as ID 207, instead uses ID 202 (ANSI). Fixed in SU2 (r. 2666480).
Back to top
Login Window
Login Window is an application that runs as a part of the boot
process allowing users to sign in, and protecting the system software
from unwarranted access.
- Login window would fail if the AFP user home directory was
specified as one level down in the home directory (r. 2660640).
- Login window changed to display the appropriate About Box and Login
Panel for Mac OS X Server depending upon the existence of the
/System/Library/CoreServices/ServerVersion.plist file (r. 2669206).
- When login window mounts an AFP share point for a users home
directory, it will now specify the kCreateNewSession flag in the options
parameter to mountURLPtr. Otherwise, the AppleShare client will re-use an
existing session to mount the requested sharepoint. This resulted in
incorrect access privileges in the home directory (r. 2665928).
Back to top
Network Services Location
Network Services Location (NSL) allows you to register and search for services on a network in
a protocol-independent fashion. New features and corrections
found in NSL include:
- Directory Agents services refresh check-up on idle was incorrectly set to
happen every 3 minutes instead of every 3 hours as originally intended.
Changing the units fixed that problem (r. 2681863).
Back to top
ntpd
The ntpd (Network Time Protocol Daemon) is a background task that synchronizes
the system clock with known time services on the Internet.
Back to top
prebind
Prebinding is a process that optimizes the performance of Mac OS X applications
so their launch times are improved. Additional information about the Prebinding
process can be found on the developer web site at the address
http://developer.apple.com/tools/projectbuilder/Prebinding.html The following changes have been made to the
prebinding process. Issues addressed in this update to prebind were, for the most
part, related to problems that could occur during the "Optimizing System Performance"
portion of installations.
- Prebinding could use up about 100mb of disk space during execution that would
not be recovered until the system was restarted. This problem has been corrected
so that the disk space is recovered when prebinding is complete (r. 2675783).
- Assorted problems that could crash prebinding during execution have
been corrected (rr. 2670541, 2648491, 2680789, 2686472).
Back to top
Smart Card Support
PC/SC is a standard that builds upon existing industry smart card
standards - ISO7816 and EMV - and complements them by defining low-level
device interfaces and device-independent application APIs as well as resource
management, to allow multiple applications to share smart card devices attached
to a system.
- Update 10.0.2 adds support for the PC/SC standard in Mac OS X (r. 2682593).
Back to top
Video Drivers
This is the system software component responsible for controlling the video
graphics circuitry.
- A problem preventing the use of an External Monitor with
some iBook models was corrected (r. 2658780).

This section describes changes provided in the 10.0.3 software update
that have not been categorized into separate sections.
- A problem affecting low level system routines used for iterating
over files in directories was corrected (rr. 2680605, 2688546).
Mac OS X version 10.0.4
This section describes changes provided in the 10.0.4 software update
that have not been categorized into separate sections.
Audio
Audio services built into Mac OS X export APIs for playing back and
recording digital sound samples in a number of popular formats.
- The wrong audio driver was being loaded on some
PowerBooks (r. 2662883).
- Audio circuits were not being closed on some PowerBooks when
going into sleep mode, resulting in an extremely unpleasant
screeching noise, something like a "mutant tea kettle coming
to a boil" (r. 2683816).
- The sound control panel settings for headphones were not being honored
on some Beige G3 models. Now they are (r. 2685033).
- A problem where Sound Preferences adjustments to volume or balance
settings were causing sound distortion has been corrected (r. 2696488).
Back to top
Carbon
The Carbon API set provides human interface services for use in
applications programs. These facilities include the Window Manager,
the Control Manager, the Multilingual Text Editor, et cetera.
- A problem preventing "Dead" keys (like option-i-i ) from showing
up in
KeyEvents sent to Java applications has been
corrected (r. 2658544).
Back to top
Carbon Core
The Carbon Core incorporates essential services that are generally
devoid of a user interface. These facilities range from memory management
to process management.
- The
SCSIBusInquiry routine was not
returing correct results. It has been corrected so
now it works as expected (r. 2663764).
- The routine
SCSIBusInquiry would crash
inside of calls to SCSIAction when no SCSI
bus present. This has been corrected and SCSIBusInquiry
now returns an error code as it should (r. 2688494).
- The
NewSCSICallbackUPP routine was not
returning a correct value. In this case, the callback
glue was incorrect in the SCSCICallBackUPP.
This has been corrected in software update 10.0.4 (r.
2688501).
SCSIBusInquiry calls on machines with multiple
SCSI busses installed would show devices attached to one bus
as registered on every bus. This has been corrected (r. 2693298).
- Completion routines provided in calls to
SCSIAction
were not being called for commands issued to non-existant devices
(r. 2693361).
- The application stack size field in the
'cfrg'
resource of Carbon CFM applications was being ignored and the
stack size was always being set to a default size of 512K.
LaunchCFMApp now uses this field to and sets the
stack size appropriately. The maximum stack space that can
be allocated using the 'cfrg' mechanism is now
64M (r. 2694324).
Back to top
Classic
The Classic environment is actually a full version of Mac OS 9.1
running in a protected memory space under Mac OS X. As a result,
most Mac OS 9 compatible applications will run side-by-side with
Mac OS X applications. This allows users to upgrade to Mac OS X
without fear of application incompatibility.
- Under some circumstances, it was possible for the key down
state information maintained inside of the Classic environment
to get out of sync with the keyboard. This has been corrected
and should no longer occur (rr. 2667096, 2658460, 2658881).
- Under some circumstances, it was possible for the mouse cursor
to disappear in the classic environment. This would only happen
when the Classic environment was switched into the background
and some software running in classic attempted to hide the cursor.
In this case, no actual calls to hide the cursor were being
made, however classic's internal cursor state was getting out
of sync with the actual state of the cursor. This has been corrected
so that now, in the majority of these casses, Classic's internal cursor
state is synchronized with the calls being made to set the state of
the cursor (r. 2696069).
- A problem where TCP connections over PPP would fail in Classic networking
applications if TCP Header Compression was turned on was corrected (r. 2696070).
Back to top
Core OS Networking
Core OS Networking provides all networking services in Mac OS X. Other
networking services, such as Carbon's Open Transport APIs, are built
on top of Core OS Networking.
- PPP now pays attention to the "Send PPP echo packets" option in the
Network panel of System Preferences (r. 2681672).
- A problem where ICMP messages exceeding the MTU size would not
be received by classic applications has been corrected (r. 2522913).

Disc Recording
The Disc Recording framework (introduced with update 10.0.2) includes
device drivers for recording CDs on machines with built in recordable CD drives
as well as a variety of the most popular 3rd party extenal USB and FireWire drives.
- Fixed problems with various internal and external CD-RW drives. These
fixes were related to recognition of the specific drives, reliable CD
burning, TOCs with odd numbers of bytes, and kernel panic problems
(rr. 2683314, 2684879, 2688442, 2693251, 2693255, 2693268, 2693278,
2693264, 2701242).
Back to top
FireWire
IOFireWireFamily.kext and related services provide Apple's
support for the IEEE 1394 High Performance Serial Bus standard.
- Under rare conditions, a reboot could result in a kernel
panic when multiple FireWire devices were present. (r. 2648149).
- Headphones no longer receiving audio on a wake from sleep mode (r. 2689355)
Back to top
Installer
This section describes changes to the Mac OS X installer program.
- A problem where the Installer would not restart computer
after an install when the restart button was both present in
the final acknowledgment window and it was pressed by the user
has been corrected (r. 2530722).
- Fixed a bug where installing software could improperly change the
permissions of existing system owned directories (r. 2646401).
Back to top
IOKit
IOKit provides low level APIs for driver writers interested in making
their hardware products work with Mac OS X.
- New definitions were for some structures used in IOKitUser
have been provided in
IOUSBLib.h (r. 2695039).
Back to top
Kernel
The Kernel is the lowest level part of the operating system that mediates all access between
higher level system software services and the computer hardware.
- Fixed a problem in the kernel that could cause
select on sockets
to return a
timeout even though data had arrived (r. 2680180).
- Fixed the HFS implementation so that calls to PBSetCatInfo now correctly
set the modification date. This was causing numerous problems for Carbon
developers; for example, just opening a header file like "MacTypes.h" could
cause your entire source tree to rebuild. (r. 2651481).
Back to top
Mass Storage
This section discusses changes to device drivers used for accessing
various storage devices.
- Fixed problems with various internal and external CD-RW drives. These
fixes were related to recognition of the specific drives, reliable CD
burning, TOCs with odd numbers of bytes, and kernel panic
problems (rr. 2685583, 2685789, 2688442, 2693251, 2694511).

- Fixed a problem where a power alert would come up when a self-powered USB 2.0
hub was connected to the keyboard port (r. 2681047).
- Relaxed the matching rules to allow additional matching criteria beyond
those defined in the USB Common Class Specification if the matching
personality includes
idVendor or either bDeviceClass
or bInterfaceClass.
Added more debug logging when a driver does not match. (r. 2587298).
- Improved the HID Managers ability to report certain HID related
properties (r. 2682971).
- Took IOUSBHub out of the IOUSBFamily and moved it into its own
separate driver (r. 2645719).

cases where it could occur (r. 2633741).
- Added API to retrieve vendor, product, and release strings for USB
devices without requiring a connection (r. 2664895).
- Problems with various keyboards and mice which became unresponsive
if left idle for some time or when coming out of sleep have been corrected
in the majority of cases where they could occur (rr. 2679696,
2599713, 2629953, 2624423, 2486041, 2437545, 2635140, 2615364, 2507831).
- Added support for USB device reset (r. 2689555).
- Improved the fidelity of USB error codes (r. 2690450).
- Added some new constants in "USBSpec.h" (
kUSBVendorID,
