The Firewire Disk don't work After Snow Leopard 10.6.1

Dear Apple friend
I've a big problem... I've 6 firewire external hard disk (400 and 800) with my work.
And now I can use it after Snow Leopard update to 10.6.1.
How I can resolve it???
I need to work!!!!
thanks
Walter from Italy

Have you reset the FireWire bus? Did you try a different cable?
If so and things still don't function properly your only choice may be rolling back the system.
If you search these forums and with Google you will find lots of issues like these. If you need these disks to work your only choice is to roll back your system software.

  • HP Photosmart C6300 printer/scanner not working after Snow Leopard install

    HP Photosmart C6300 printer/scanner not working after Snow Leopard install
    Reinstalling etc does not work - does anyone else have the same problem or a clue as to how to fix this?

    Keith,
    I got a C6280 and the scanner does not work anymore. I am for 6 days in contact with HP. The last printer driver install form the apple web site does not open the image of HewlettPackardPrinterDrivers.dmg because of an invalid checksum. The skipping of the validation gives and error in the install.

  • A fix for screensavers that don't work with Snow Leopard?

    is there a fix for the screensavers that no longer work with Snow Leopard? some of the developers have came out with new versions, but a few of them have been abandoned by their authors. Is there a way to run those screensavers in 32 bit mode?

    Is there a way to run those screensavers in 32 bit mode?
    Not without action by the original authors, sorry.
    I know it doesn't help right now, but like all other OSs in the past, these types of things need to catch up since the bar has been raised once again...give it time and there will tons of entertaining s'savers out to pick from.

  • Isight no longer works after snow leopard upgrade

    my isight no longer is available directly after snow leopard upgrade on my macbook black. Anyone else with the same problem? The isight does not show up in 'about this mac' under USB and I tried resetting SMC and PRAM.

    Hi,
    In Leopard there was an App called iSight Update app that was in Hard Drive/System/Library/Core Services
    This does not seem to be there in Snow Leopard.
    An issue with some computers with the camera was that in System Preferences > Displays the Colours needed to be set to Millions.
    Also check the Hard Drive/System/Library/Extensions folder and see that you have the Apple_iSight.kext (this is likely to handle the Internal iSights as well).
    One last thing.
    Some Web sites can make use of the camera using Flash.
    If that tab is still open the Browser may have use of the camera.
    It sounds like you have done computer restarts and this will not be the case unless the browser is set to go back to that page.

    I agree. When I tried using symlinks to send calls to bash & sh to tcsh instead, I found a lot of broken shell scripts. I don't think tcsh has been maintained very well since it's use with OS X 10.0 through 10.2.  I had better luck with xsh, though.

  • MPEG-2 Playback not working after Snow Leopard upgrade

    Something I need all the time is MPEG2 playback in Quicktime and to ability to convert from MPEG2. in MPEG Streamclip.
    What I have found out is Snow Leopard deletes the file in library/quicktime when you install.
    I have followed the instructions to go back in the time machine, get the file, restore it back into the library/quicktime file
    Done all that, rebooted etc....still nothing
    I have also found the quicktimeMPEG2 components installer and that doesn't work either
    I desperately need this to work as my business relies on it.
    Any help appreciated
    Cheers
    Paul

    What error message do you get with the dmg installer? I have just tried an MPEG2 file, after upgrading to SL, QT reported it required the meg2 component. I found the original dmg file I purchased and it installed OK and works with QT 10.
    Before trying to install again it may be worth repairing permissions on you disk.

  • NAS capabilities of the Time Capsule as media server after Snow Leopard

    Why does Apple have to prevent the Time Capsule being used as a media server? I accept that it was never sold as such but pre-Snow Leopard it worked fine and was the ONLY reason I bought it in the first place.
    I don't like Time machine. I have my own back-up procedures in place to take care of that. What I DO like is being able to have all my media in one place in my house instead of scattered across four machines. I also like that I could back up all the TC content onto another external connected to the USB socket on the TC.
    It all worked well, gave me the security of knowing my media was being backed up daily and also freed up a lot of space on my other Macs.
    With the advent of Snow Leopard Apple has rendered my music server as good as useless, prevented my ability to make scheduled back-ups and is forcing me to reconfigure my system with a proper NAS so I don't risk losing over 40,000 music files and 1000s of original photographs should the hard drive in the Time Capsule fail.
    This will cost me well in excess of £500 and a lot of my time. Then I will have a redundant 1TB Time Capsule and another redundant 1TB external hard drive.
    Why does Apple see the need to disable this functionality? If it doesn't support it how does it know it needs to prevent it? What is the issue here? All Apple seems to do is upset a lot of people who have made an investment in Apple equipment only to have the primary reason they bought it killed off.
    Am I wrong here? Have I made some kind of configuration error that means my TC just disappears from my desktop and my iTunes stops playing?

    Okay, I've actually posted about this issue before but was simply told that 'Apple do not support the Time capsule as a media server', but this is my experience...
    I have a modem/router supplied by my ISP that distributes wireless at 'g' standard - fine for our iPhones, but all our Macs are modern Intel models capable of using the 'n' standard.
    So I bought the Time Capsule for two reasons - one to give us that faster wireless service and two to act as a media server by consolidating all the music, video and photo files we had in duplicate and triplicate across the four machines in our household.
    The TC was connected to the router via gigabit ethernet and then via ethernet to my 3.06 iMac from where everything is managed. Wireless 'n' standard access at 5GHz was provided to our laptops and as expected every machine could 'see' the TC on the network.
    I then moved all our media files onto the TC with no problem and added a 1TB external drive to the TC via the USB port. I then discovered that Chronosync installed on my iMac could see the TC and the TC Back-UP drive so I used that to copy everything over and set up a schedule to ensure that regular copies of new files were made.
    I then added both the TC and the TC Back-Up to my login items so they would automatically mount on the desktop upon start-up. Restarting the machine proved this worked fine so I proceeded to point all the Macs' iTunes libraries to the new location on the TC and set them NOT to copy the files over when adding to library.
    This all worked fine and all the Macs could access and play iTunes, surf the internet etc. except in the distant corners of the house. To help coverage I bought four new Airport Expresses with 'n' capability and set each one to extend the wireless network created by the TC.
    Then I added an Apple TV and linked that to the TC network too. This again was managed via iTunes on the iMac and set to automatically synch new recordings made via my EyeTV.
    This whole set-up has worked flawlessly for over a year and until I installed Snow Leopard.
    When I first restarted after installation on my iMac I really noticed nothing. The TC mounted as usual and when I started iTunes my Apple TV began to automatically synch. Everything seemed to be operating normally. However when I double clicked the TC icon to access my files I got a warning message saying 'The alias “TIME CAPSULE” can’t be opened because the original item can’t be found.' I was given the choice to delete or fix the alias or just go Okay. When I chose 'fix' a new Finder window opened where the TC was clearly visible in the left column and it said I was connected. But in the next column both the TC and the TC Back-Up were greyed out.
    I then dragged the TC to the Trash on my iMac and I could hear it spin up and then it finally moved.
    I then opened a new Finder window, selected the TC and it came up with a preview calling it a 'Sharepoint' and no longer like a normal hard disk.
    Meanwhile I realised that because iTunes was no longer 'seeing' the TC it had defaulted to the Music folder in my Home folder and was now busy deleting all my Apple TV stuff because it couldn't find the originals.
    This has been going on for several weeks now and I am increasingly frustrated by trying to find a workaround. Meanwhile Chronosync no longer makes scheduled back-ups because the drives don't mount on start-up - well they do as aliases but that's no good if they're not linked to the originals!
    What bothers me is that all this stuff worked like a dream under Leopard - indeed many others have similarly used Time Capsule as a media server and must no doubt be seeing similar issues to my own.
    If I can't continue using the TC this way then Apple have essentially removed the very functionality I bought it for and thus rendered it useless.
    Of course if there is a glaring configuration error or even an adjustment post-Snow Leopard that needs to be made then please tell me. However the original reply to my older post of 'Apple do not support the Time capsule as a media server' does not leave me with much confidence in getting this resolved any time soon.
    I have everything crossed however...

  • IMPORTANT GUIDE FOR ANYONE WITH AN HP DEVICE NOT WORKING AFTER SNOW LEOPARD

    To anyone with an HP printer/scanner device,
    After being frustrated with my HP Photosmart C4580 not being able to scan for over an hour (scouring the forums, HP's website etc), I've come to realize my problem. Note that this has only been tested on a device that is plugged in DIRECTLY to your mac. I have not tried this over the network and do not plan to since my house is not set up for that.
    Anyone who is having any issues with their device, UNINSTALL the HP software. The software is simply incompatible with SL and will mess up your devices! HP even says so on their website (see link below)!
    http://h10025.www1.hp.com/ewfrf/wc/document?docname=c01846935&cc=us&lc=en&dlc=en &product=1153481
    This is easily done by going to your applications folder > Hewlett Packard > HP Uninstaller. After using the uninstaller to uninstall HP's apps from your computer unplug your scanner from your computer and power supply. Now to make sure there are NO printers registered with your computer that could possibly mess up the fresh driver install, go to System Preferences > Print & Fax. Right click anywhere in the left pane (where any printers you have/had installed will be located) and click "Reset Printing System". This will wipe out any traces of a printer so you can start a-new.
    Now, restart your computer. After it is restarted, plug your printer into the power source, then when it is fully booted up you may plug it into your USB slot. Then, go to System Preferences > Print & Fax. Click on the "+" (which will give you the interface to add your printer), select your printer (which you should note will say "USB Multifunction" instead of "USB" which is what showed up with the HP software still installed), and click "add". Your mac will do the rest (installing the drivers and such) and you should be able to print & scan as usual.
    Note that you will need to scan using Preview, Image Capture, or your Printer Queue due to the changes with Snow Leopard (see the HP link above to learn how to use these). Your device should now properly show up when you use these applications to try and scan now.

    @lakewood - there is nothing specifically in Software Update if you upgrade from Leopard to Snow Leopard. For me anyway..seems like thats the case for everyone though.
    @ruger - so it won't even let you hit the '+'? For me, I had to hit the '+' to get it to install which in turn automatically downloaded the proper software/drivers for my device. if i were you, i'd see if i could get that to happen and hit '+' to install it. also - make sure you don't have any of the HP software on your computer also (use the uninstaller provided!)..that was really what did the trick for my machine. HP has come out and specifically said to not use the device manager, but that didn't quite do it for me. i had to uninstall everything that came on that CD (its all located in applications > Hewlett-Packard and, like i said, can be uninstalled easily using the provided uninstaller).
    if all else fails, what i've also heard helps is just to reinstall snow leopard. that'll make sure everything is fresh. i'd delete all your printers like i outlined in my first post first THEN reinstalling it if you wish to go that route. however, it really does sound like the driver is messed up if its pausing and works fine with time capsule. idk how old the printer is, but sometimes with older models, the support blows. i apologize if none of this helps whatever the reason for your troubles may be, though.
    Good luck,
    -Mike S
    PS: printers are always terrible to upgrade on everyone's end. consumers, operating systems, and manufacturers. it stinks that nothing can be generic and run similarly anymore =/

  • ISight not working after Snow Leopard update?

    I just realized my iSight isnt working. I dont see it in System Profiler and I remeber prior to the Snow Leopard upgrade the iSight was working fine.  This was three months ago, since the update i never had to use it until now.  I tried resetting the SMC, I tried the command + option + p + r and still nothing.

    •  If you have not already done so, restart Mac and
        try again.  If the iSight still does not work, continue.
    • If Apple's http://support.apple.com/kb/HT2090
       suggestions do not help you, (are you certain that you
       used the correct "reset" procedure?), yours may be a
       hardware problem that will require a professional fix. 
       Unless you have a current backup, make one now.
      Then consider the final "Troubleshooting" suggestion:
    "... contact Apple or an Apple-Authorized Service Provider for service."
    • If I understand correctly, you are now using Snow Leopard.
       If you want to try one more thing on your own before
       seeking professional help. use Disk Utility to repair permissions.
       Then download and apply the latest Combo Update
       for your OS.  The latest SL Combo Update at present is here:
         http://support.apple.com/kb/DL1399
    • Repair permissions again immediately following the system restart
       that completes the Combo update.
    Properly applying the Combo version of updates
    can sometimes correct problems like yours.

  • Airporter does not work after snow leopard upgrade

    I upgraded my old macbook to snow leopard, and the Time Capsule can not detect the disk drive on the Airporter.  The laptop has no problem using airporter to get to the internet, and the airport utility can see the disk drive.  After the install of snow leopard, I saw the time capsule, and it asked if I wanted the file recovered from the time capsule. This seemed to work perfectly, and made the upgrade painless except my time capsule does not work anymore.

    I have the metadata.mds.plist but I do not have the Spotlight.plist as well. Regarding a fix, I had a similar issue with Spotlight's index when I upgraded one of my iMacs. A clean install, properly resolved the issue. I'd be curious if a reinstall of Snow Leopard would take care of the issue, as the A&I feature isn't there anymore I've yet to determine what exactly the install of SL over SL would do. My understanding is that the A&I is performed, it's just not called as such.

  • Aperture will not work after snow leopard instalation,

    Hi,
    I have avoided upgrading to Snow Leopard but my children bought me the upgrade for Christmas as they want me to use Face Time. So I did, now aperture will not open and it says contact the originators of the program. I am a pro photographer and all my current work is on Aperture and I have a wedding in two days time and so this is somewhat disturbing as all my post production in done in Aperture. Can anyone help me I have done all the software upgrades etc.....

    Are your images files managed in the Aperture Library, or Referenced? Do you have an external disk drive in the configuration, and if so, is it formatted as Mac OS Extended?
    If you hold down the Option key while clicking on the Aperture Icon in the Dock, do you get the dialogue that allows choosing between different Aperture Libraries, or even creating a New Library?

  • DVD Drives not working after Snow Leopard install

    Hello all. I'm having problems after installing Snow Leopard. Om my MacBook Pro, my DVD drive doesn't even read discs anymore. It keeps it spinning for a while and then ejects it.
    Coincidentally, the drive on my iMac 3+ GHZ is not accepting my discs into the DVD drive. It's not sucking in the discs anymore.
    Both of these things started happening right after the Snow Leopard installation.
    Can anyone help?

    Have been running without trouble and had total ability to burn disc images to DVD until SL installation. after installation, every burn attempt fails to complete, give me an unrecoverabl, unable to restart error. I does burn data to the disc, but fails at some point near the end of the burn wich renders the disc a "coaster". I put my spare HDD back in wich was running 10.5, the problem exists with that drive also. My next step was to load a fresh drive with 10.5, even then the problem exists. I find it hard to believe that the drive failed exactly when SL was installed, more likely that the installation changed a hardware setting, or installed a firmware update which cause the problem. As I am a repair tech, I have done a ton of reaserch on the subject, and I find that litterally 10's of thousands of people have had the same issue after the SL upgrade. Come on Apple, I always heard you were better than Microsoft, but as everyone can see there is a problem. Get working on the fix and patch it just like Microsoft.

  • Why doesn't the desktop 'snap to grid' work with Snow Leopard?

    I've recently upgraded my OS to Snow Leopard and I do a lot of work with photo folders which I keep organized on my desktop. Since upgrading the 'snap to grid' function in the view options of the desktop preferences has stopped working. For some reason the folders and files on the desktop keep snapping off the screen or on top of each other so that I cannot find them easily. I've had to turn off the 'snap to grid' and the desktop no longer looks organized and is not easy to navigate. Why is this happening? AND, how do I fix it? It seems to me the snap to grid shouldn't have gone out the window with an upgraded OS. I'm very organized and borderline OCD so this is FRUSTRATING me to no end!!!
    Anyone have any ideas?

    It's working for me in 10.6. Try moving this file in your Home Folder/Library to the trash -- don't empty it yet.
    /Users/yourusername/Library/Preferences/com.apple.desktop.plist
    When finished go back to the Desktop>View Options and select Snap to grid.
    If that doesn't do it, open Terminal in utilities and copy/paste this command, then hit return. Don't attempt to type it in by hand. If you make a typo or get the spaces wrong, there could be a disaster. When finished go back to the Desktop>View Options and select Snap to grid.
    rm ~/Desktop/.DS_Store

  • TM backup disk cannot be found after Snow Leopard install

    Message from elsewhere re-posted here after helpful advice from Apple Discussions Team.
    Just installed Snow Leopard (with TM switched off though not unplugged) and got all the software updates available. I re-installed the TM installation disk. Everything went ok until I wanted to restore from my Time Capsule. I switched the big switch on. TM is continuing to make backups but when I want to locate folders to restore TM won't go back further than the day I installed Snow Leopard. Having selected the TM disk and entered the password the dialogue tells me that the TM backup disk cannot be found and offers me the select disk dialogue again. I have gone through the unplug/plug routine.
    Through Migration Assistant I tried the contents of my Pictures folder (including all my iPhoto libraries) but it just supplied an empty folder. Since I didn't migrate at the time of the Snow install I wonder whether it was migrating the earliest backup it had made after the Snow install. This would make sense if "the Time Machine backup disk cannot be found", as the dialogue keeps telling me.
    Anyone any ideas?

    I'm not sure just what you did.
    Did you reinstall Snow Leopard? Did you do a full restore?
    First, just re-select your Time Capsule in TM Preferences.
    If that doesn't help, try a "Full Reset" of TM per #A4 of the Time Machine - Troubleshooting *User Tip* at the top of this forum.
    If that doesn't help, see #E2 there.
    If still no help, use the Finder to see if you have two sparse bundles on your Time Capsule. If so, try mounting one manually by double-clicking it, then using the Browse option per #E2.
