- Addresses potential vnode reference count mismatches that could lead to a kernel panic.
- Addresses USB audio issues for PowerPC Macs; for example, latency is improved. Addresses several AppleScript issues, including: Preservation of property values in Script Menu, a potential Bonjour issue with "choose remote application", an invisible "choose application" dialog issue, and improved compatibility with Dashboard widgets and applications.
- Includes recent Apple security updates.
Update process recommendation We recommend the following procedure when installing Mac OS X 10.4.6.
First, avoid performing any other operations (in Mac OS X or third-party applications) while the update process is occurring. In addition, before installing this security update, make sure all Apple-installed applications and utilities are in their original locations. Moving one of these applications to a different location on your hard drive can lead to an incomplete update. Also, disconnect any FireWire/USB devices before applying Mac OS X 10.4.6 (except for your startup drive, if it is FireWire or USB), then re-connect the devices one by one after the update process is complete and the system has restarted.
If you'd like to take an even more cautious route, use the following process:
- First create a backup of your startup volume.
- Drag the folder com.apple.SoftwareUpdate located in /Library/Caches (the Library folder at the root level of your hard drive) to the trash.
- Download the standalone version of Mac OS X 10.4.6 and save it for later.
- Startup (restart) your Mac using a drive other than your usual startup drive as the boot volume. This can include an eDrive created by TechTool Pro, or better, an external FireWire. Make sure that this drive includes a copy of Disk Utility (which can simply be copied from your normal startup volume).
- Launch Disk Utility from the temporary startup drive. Perform a "Repair Disk" operation on your normal startup drive (which should now appear as another mounted volume in the Finder)
- Again restart, this time booting from your normal startup volume, while holding the "Shift" key to boot in Safe Mode.
- Apply Mac OS X 10.4.6 and restart when prompted, this time without holding the "Shift" key.
As with previous iterative Mac OS X releases, the startup time after first installing Mac OS X 10.4.6 can be inordinately long. Don't panic if you are stuck at the grey progress screen for several minutes after the update. Subsequent restarts should take place at normal speed.
General purpose workarounds
Three workaround routines will solve many of the issues that are indirectly caused by Mac OS X 10.4.6 installation (i.e. not due to bugs or flaws in the update, but pre-existing system conditions that may be triggered by the updater process).
The routines are as follows:
Delete kernel extension caches, other caches for some issues A number of common issues that crop up after incremental Mac OS X updates can be resolved by deleting specific cache files -- specifically kernel extension caches -- and restarting.
This can most easily be accomplished with a shareware utility like Tiger Cache Cleaner, but also bears a manual process which involves dragging the following files to the trash:
- com.apple.kernelcaches (a folder in /System/Library/Caches)
- Extensions.kextcache (a file in /System/Library)
- Extensions.mkext (a file in /System/Library/)
- com.apple.ATS (a folder in /Library/Caches/)
- Files that start with com.apple.LaunchServices (in /Library/Caches)
You will be prompted to enter your administrator password when dragging these files to the trash. You may need to restart after moving them to the trash.
Re-apply the Mac OS X 10.4.6 combo updater A workaround that has proved successful for various problems caused by previous incremental Mac OS X updaters is re-application of the current combination updater (PowerPC or Intel). Doing so overwrites potentially problem-causing files that were not replaced by the "Delta" (adjacent version-to-version) update.
Re-apply the Mac OS X 10.4.6 combo updater from an alternate startup volume
- Download and save the Mac OS X 10.4.6 combo updater (PowerPC or Intel).
- Startup from an alternate boot volume, such as an external FireWire drive, or use another Mac to boot the problematic system in FireWire target disk mode (connect the two machines via a FireWire cable, and boot the target [problematic] system while holding down the "T" key)
- Once booted from an alternate drive, select the problematic volume in the Finder, and "Get Info" -- either by pressing the Command-I keyboard combination or accessing the "Get Info" option in the File menu. Check the box marked "Ignore ownership permissions on this volume."
- If you have a third-party disk repair utility like DiskWarrior, use it to re-build the directory on the problematic volume (this step may not be necessary)
- Re-install the Mac OS X 10.4.6 combo updater on the problematic drive.
- Re-attempt booting from the problematic volume (hold down the option key at startup to select the desired drive)
