Capping a very busy update week for Apple, the company has released Mac OS X 10.4.8 in both Intel and PowerPC versions.

The full list of enhancements is as follows:


  • Adds support for CDSASSL (Common Data Security Architecture Secure Sockets Layer) printer connections.
  • Addresses an issue for Mac OS X 10.4.7 in which some documents containing some Chinese or Korean language characters might not print as expected.

Finder and Apple applications

  • Resolves an issue in which a Finder alert message with the buttons "Initialize", "Ignore", and "Eject" might not appear after connecting a partitioned FireWire hard drive.
  • Addresses a potential issue in which Preview may unexpectedly quit.
  • Improves reliability of iTunes syncing with certain iPod models.

Networking and modem

  • Resolves performance issues that could occur when connecting to a Comcast network.
  • Improves security by adding support for EAP-FAST for AirPort wireless authentication.
  • Improves Express Card behavior for portable Intel-based Macs.
  • Improves reliability for connections made in Ireland with an external Apple USB Modem.
  • Improves connection reliability for external Apple USB Modems when resuming an Internet connection after answering an incoming call.
  • A computer restart is no longer needed to restart nfsd.
  • Improves Apple File Sharing client performance by changing the default AFP WAN quantum size.. More...
  • Windows File Sharing now generates only one process, avoiding an issue that could cause a Mac OS X computer to become unresponsive if it won a master browser election.
  • Improves reliability when faxing in France or Belgium via an external Apple USB Modem.


  • Resolves an issue for Microsoft Word in which Word might stop responding when saving a file that uses certain OpenType fonts.
  • Adds RAW image decoding support for these cameras: Sony DSLR-A100, Nikon D2Xs, Fuji FinePix S2 Pro, Fuji FinePix S3 Pro ( Highlights) and Konica Minolta 7.
  • Resolves an issue in which thumbnails may appear blank when importing RAW images from a Canon 30D camera.
  • Resolves an issue for Microsoft PowerPoint in which the display resolution might not change as expected after switching from a PowerPoint presentation to a different application via Command-Tab.
  • Improves compatibility for Canon EOS Utility software after connecting a Canon EOS Kiss Digital camera to a PowerPC-based Mac.
  • Improves compatibility for the TV Tracker 2 Dashboard widget.


  • Includes recent Apple security updates.
  • Improves the accuracy of Rosetta numerics and addresses Altivec translation issues on Intel-based Macs.
  • ColorSync matching no longer fails when using a V4 ICC profile in an application opened with Rosetta on an Intel-based Mac.
  • Addresses an issue in which some USB devices connected to a PCI card may not be recognized after starting up or waking the computer.
  • Resolves an issue in which external USB-based video cameras may not be available after quitting the application that is using it.
  • Reduces time needed to transfer data from a USB-based image scanner.
  • Improves responsiveness of the Translation Dashboard widget.
  • Addresses an issue in which text typed with the Hangul input method may not be visible while the Caps Lock key is active, on PowerPC-based Macs.
  • Adds support on Intel-based Macs for multiple cores to LAPACK and BLAS routines in the Accelerate framework; the maximum number of threads used by Accelerate BLAS routines is now limited by the environment variable VECLIB_MAXIMUM_THREADS; addresses an issue with some complex BLAS routines in the Accelerate framework that were encountering an illegal instruction.

Mac OS X 10.4.8 is available through Software Update, or via the following standalone download links:

If you are experiencing problems after the update, please let us know.

[Delta updates are capable of updating version-to-version, i.e. Mac OS X 10.4.7 to Mac OS X 10.4.8. Combo updates can update any version of Mac OS X 10.4.x (e.g. 10.4.3) to Mac OS X 10.4.8]

Update procedure recommendation We recommend the following procedure when installing Mac OS X 10.4.8.

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 10.4.8 (except for your startup drive, if it is FireWire or USB, and your keyboard/mouse), then re-connect the devices one by one (checking for issues created by any particular device) after the update process is complete and the system has restarted.

Also, note that the first restart after applying Mac OS X 10.4.8 may be abnormally long. Subsequent restarts should take place at normal speed.

Common workarounds If you have problems after applying the delta (standard, smaller) update, try the following common workarounds:

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:

  • (a folder in /System/Library/Caches)
  • Extensions.kextcache (a file in /System/Library)
  • Extensions.mkext (a file in /System/Library/)
  • (a folder in /Library/Caches/)
  • Files that start with (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 10.4.8 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 10.4.8 combo updater from an alternate startup volume

  1. Download and save the Mac OS X 10.4.8 combo updater (PowerPC or Intel).
  2. 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)
  3. 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."
  4. 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)
  5. Re-install the Mac OS X 10.4.8 combo updater on the problematic drive.
  6. Re-attempt booting from the problematic volume (hold down the option key at startup to select the desired drive)

Downgrading to Mac OS X 10.4.7 If you are experiencing severe, seemingly insoluble issues after the update, you can revert to Mac OS X 10.4.7 per the instructions in this tutorial.
