  1. I hope it fixes whatever has been making Dictionary crash all the time. System Preferences crashes about every other I launch it, too. Really annoying. Has anyone else been having these issues with Snow Leopard?

  2. @spj:

    I’ve never had any crashing issues with Snow Leopard, nor have I heard of any widespread complaints. Would advise downloading the 10.6.3 combo updater from the Apple website and installing manually rather than relying on Software Update.

  3. @spj:

    Ditto with never having crashing issues with Snow Leopard, particularly with Dictionary and System Preferences. Could it be a font problem with Dictionary, and have you validated fonts with FontBook? (Just guessing.) The only thing I could imagine messing with System Preferences is a corrupted preferencepane, maybe a third-party one, though I’ve got several (FlipForMac WMV, Glimmer Blocker, Growl, Perian and SizzlingKeys) and I’ve still never had it crash on me.

  4. Going off my experience running 12 macs at work, there are no problems with SL unless you migrate from an old machine to new one – you are better starting afresh with the new one.

  5. alansky: Thanks for your comment. These Dictionary and System Preferences crashes are the only ones I’ve ever had with Snow Leopard, and they have only been occurring within the past few weeks. I’ll try updating the slow way this time, though, as per your suggestion, albeit not for a day or two. Just like I’m not a x.0 kind of person, I also generally wait a couple days before doing any OS update just to make sure no widespread problems have been reported.

  6. Rich Apple person: Still nothing with Mail’s problems with 3rd party IMAP’s and POP’s asking for password all the time

    The problem is with your mail provider – the remote server is declining your stored passwords (and usually it’s the server’s fault).

    I agree that there should be an option “I know the server has just screwed up – ignore & retry” instead of having to input the password again and again…

  7. I ran Validate Fonts in FontBook and it found 37 “minor” problems. Would this automatically mean I should delete all of them? I can certainly live without a few of them, but most of them are standard (and often Web-safe) fonts like Ariel, Verdana, Times New Roman, etc. I don’t want to delete those. Any suggestions on how I should proceed?

    Again, I appreciate all the advice.

  8. so… installed the 10.6.3 update, all went well – rebooted my Mac Pro and now my second monitor doesn’t work at all. gets no input from the second DVI port on my video card. i’m pissed, have TONS of work to do today and can’t be bothered trying to troubleshoot this ridiculous issue.

    anyone else have this problem? anything i can try? i’ve tried rebooting, removing the re-inserting the video card, switching monitor cables – both monitors work just fine, but only one at a time, and only from the first DVI port on my video card.

    any help would be appreciated…. dual monitor users, BEWARE before updating to 10.6.3.

  9. Installed on both my MacPro and MBP 15 Unibody – no problems… in fact, several issues are now gone:
    dictionary disappearing, System Preferences no longer crashes, my teeth are whiter and the girl next door is now smiling a me – again. Maybe she removed that restraining order!!! (Just kidding about the last two) ” width=”19″ height=”19″ alt=”wink” style=”border:0;” />

    Update seems effortless – best to D/L the combo – works better for most people.

    Cheers from Downunder.

  10. I did my 2008 MacPro (8 cores; 3 Ghz) with dual monitors and had no problems…. sorry. I have the ATI Radeon HD 4870 graphics card. One monitor is hooked up via mini-display port and the other via DVI.

    But, despite my “first post” I do note that my “Back To My Mac” links to my home computers (which use to work fine) are now gone from both computers that I’ve updated (MacPro and MacBook). I’ll have to see if, once I do the update at home, they come back.

  11. @Rich Apple person: Is it Hotmail your using per chance? That’s what I use, and what your describing happens frequently, but that’s down to MIcrosoft’s poor quality of service more than anything.

  12. @ PFjellman

    How did you prepare to run the update?
    Or did you just let Software Update run?

    1. Download COMBO Updater
    2. Run ONYX or Cocktail
    3. Run Disk Warrior or Disk Utility

    I might even clone my hard drive before running the Updater, just in case.

    4. THEN run the Combo Updater

    With an Update of this magnitude, it’s best to be careful and take some time to prepare:

  13. wonder if it cures my multiple Macs’ CVL (constant variable logout) problem. If we were talking Windows it would be big news demanding a solution. As a Mac user, despite a long running issue on forums for over a year – sufferers are deemed unlucky!

    bad show!

  14. I always clone my HD before an OS update. Saves tons of time if anything goes awry. Learned that lesson (of course) the hard way.

    Also, I repair permissions after the update, just in case.

    Snow Leopard’s font issues usually involve duplicate fonts.

    Oh yeah…installed combo update – no problems.
    Update for my MBP via Software update was about 450mb; 700+ for combo.

  15. @spj

    Just circling back and saw your question about FontBook. I’ve successfully ignored minor issues that FontBook found without any ill effects that I’ve noticed. I’ve only worried about major problems in the past. I would try turning off duplicate fonts as “It’s About Time” mentioned.

  16. Installed fine on my MacBook 3,1

    I have a TON of quality fonts installed and usually FontBook was a nightmare to launch. Now it launches INSTANTLY and displays the selected font, with no delays whatever while switching to other fonts. I’ve noticed they’ve reworked the interface slightly too. Very grateful for this update of FontBook. Sweetness and snappiness!

  17. Everything seems to be working fine with 10.6.3, on both of the Macs here that run Snow Leopard. Previously, I had an issue with Safari chewing up memory over time, when running it without quitting for a long time, such as two or three days; quitting Safari immediately released all the RAM it was hogging. It may have been related to the Flash plugin, but I’m not sure, since it seemed more noticeable when viewing a lot of videos (such as on YouTube or Hulu). Anyways, although I’ve only been using 10.6.3 for about six hours at this point, this issue (if it’s still present) seems less noticeable.

  18. used system update to get 10.6.3 and as soon as every thing was installed and restarted.. my second screen (i use a 42″ LG HD CLD TV) the colour and every thing is all messed up.. dark and stuff.. and the brightness button on my main monitor doesnt make any dif to the second screen(it did before with no probs) tried all kinds of things to fix it .. tv works fine and every thing else seams fine.. but cant work out what is going on…
    if any one can help me that would be greatly appreciated
    downloading the Combo Update and gonna see if that fixes stuff..

  19. After updating, all of my Adobe CS3 applications crash and are unusable. (Photoshop, Illustrator, InDesign).

    I have a MacBook Pro that has been serviced a couple of times under the AppleCare Warranty. Apparently, when this happens the System Serial number (the one under the battery case) is replaced with a generic text reading “SystemSerialNumb”,

    It’s my current understanding that CS3 is crashing whenever the serial number is longer than 12 characters AND/OR when CS3 applications search for the serial number and encounter the text “SystemSerialNumb”.

    There’s a great deal of passing the buck back and forth between Apple and Adobe, but meanwhile the only way I can access the CS3 applications are to revert to 10.6.2 and do an uninstall. An option to shut off the Rosetta option is mentioned, but this doesn’t apply to me.
