Snow Leopard gets updated to 10.6.3!

For those of you who’ve been itching for the latest version of OS X to come out, your wait is over. Apple released 10.6.3 today, which includes the following fixes:

  • improve the reliability and compatibility of QuickTime X
  • address compatibility issues with OpenGL-based applications
  • address an issue that causes background message colors to display incorrectly in Mail
  • resolve an issue that prevented files with the # or & characters in their names from opening in Rosetta applications
  • resolve an issue that prevented files from copying to Windows file servers
  • improve performance of Logic Pro 9 and Main Stage 2 when running in 64-bit mode
  • improve sleep and wake reliability when using Bonjour wake on demand
  • address a color issue in iMovie with HD content
  • improve printing reliability
  • resolve issues with recurring events in iCal when connected to an Exchange server
  • improve the reliability of 3rd party USB input devices
  • fix glowing, stuck, or dark pixels when viewing video from the iMac (Late 2009) built-in iSight camera

You can find the full list of fixes in this Apple Knowledge Base article.

While I personally have only seen the first two issue pop up, I’ve read reports on many of the others. Let’s hope that this truly resolves those issues. You can do the incremental update by going to the “Software Update…” option in the Apple Menu, but we generally recommend using the Combo Updater, which can be found at Apple’s Web Site.

  • We have a long-serving HP LP2465 24″ monitor hooked up through the DVI#1 port on a MacPro G5 running 10.6.0. The DVI#2 Port has a Dell 15″.

    The Mac is getting performance with the little Dell monitor, but the HP is not receiving a signal, even though it’s in the #1 port. We’re aware that we need to synch the Mac with a resolution and refresh the HP 24″ prefers, but the 1920 x 1200 at 60Hz doesn’t seem to be it. (Even though this is what another G5 with the same model monitor in our office is set at.)

    This Mac is a bit weird in that it seems to need both ports going with an active monitor for the HP to work at all. And was working running 10.5.6 right up until we did the OS upgrade.

    Any assistance would be appreciated.

    • From your description, it is difficult to determine what’s going on. You say “Mac Pro G5”. Unfortunately, those were two separate models – the G5 towers were Power PC. The Mac Pro towers had Intel processors. 10.6 will not install on a G5 – it is for Intel processors only, so I’m assuming that’s what you have.

      If both your towers are Mac Pros, try swapping the video cards. See if the problem follows the video card or stays with the machine.

      If it follows the card, it is likely that the card itself is going bad and should be replaced.

      If it stays with the machine, it can point to either corruped software on a lower level, or something else in the hardware going bad. I’d recommend backing up your data and doing a clean install of the OS on the Mac Pro. If that doesn’t resolve the issue, then you will likely want to take your machine to your nearest Apple Store or authorized repair center so they can perform a more detailed diagnostic.

  • Just purchased this item – and it doesn’t work with the latest display link driver on 10.6.3. Please advise. Thank you in advance.


  • We encountered the same issue in our testing of the updated driver yesterday – although we found it does work well in landscape mode. As far as I know, DisplayLink is working on the 90 degree rotation issue with 10.6.3 and we hope to have a fix from them on that issue soon.

    As not to lose the screen real estate, I’d suggest running both monitors in landscape mode for the time being. As soon as we have a working solution, we’ll post it here so you can rotate that monitor back to resume your normal workflow.

  • Thanks, Michael.

    Unfortunately, though, Mac OS 10.6.3 breaks that one, too.

    (And I did uninstall the previous Beta version driver properly, first, before trying the newer, non-Beta version).

    What the OS 10.6.3 update has destroyed (in both driver versions) is is the ability of the adapter to display in Portrait Mode (tall and thin) instead of in Landscape mode (short and wide).

    Selecting “90 degrees” in the “Rotation” box under Displays Preferences – which previously worked – now crashes the connected display and then, after a few attempts by the system to recover from that, freezes the Mac. :-(

    From what I’ve now read elsewhere, OS 10.6.3 incorporates a number of significant changes to the graphics and the native Apple drivers, and these seem to have burgered the ability of the OWC adapter to rotate the display into Portrait Mode.

    This is a serious problem for me – and I’m sure for many others who purchased this device from OWC, too. I bought mine specifically because of its (now Apple-broken) ability to run a second display, in Portrait Mode, next to my main display in conventional Landscape Mode – which, previously, it could do just fine.

    The technical details, in my own case, are that I’m running a 30″ HP LP3065 monitor off the dual-DVI port of my mid-2007 MacBook Pro 2.4 GHz and have been using the adapter to support a 24″ (pivotable) HP LP2465 monitor, in Portrait Mode.

    It worked a treat until the Mac OS 10.6.3 upgrade.

    You need to chivvy DisplayLink into writing a new, OS 10.6.3 compatible driver for it, pronto – because the device now no longer complies with your advertised description of it (in the very link you have quoted) as being able to display “rotated left, right or upside-down.”

    And it was, as I say, because of its ability to do just that that I bought one from you.

    Please could you get this fixed as soon as possible!

    It shouldn’t be very difficult to tweak the driver and restore this small but essential function.

    Thanks. :-)

  • Thank you Douglas for reporting this issue.

    I’ve gotten notification to the product development team here and we hope to have a solution on this shortly.

  • The issue that I need to have “truly resolved” – by OWC and as soon as possible – is the fact that this 10.6.3 update breaks the OWC “Snow Leopard” driver for the OWC “USB-to-DVI/HDMI/VGA Display Adapter (1600 x 1200) which you sell HERE:

    When will this be fixed? The driver that OWC has been supplying for months is still called a “beta” version.

    Please would OWC pull its finger out – you’re selling an item that now doesn’t work.
