Latest firmware update and more problems with 30" external displays?

Hello,
New macbook pro user since a few weeks, so first post here.
I'm aware of various issues with the displayport to dual-dvi adapter, especially with 30" 2560x1600 monitors. All threads I've found on are 1-3 years old though.
I got my 17" macbook pro a few weeks ago and I've had very few problems running my 30" dell 3008wfp as external screen. I had issues at times getting it to work after boot up, with blackout and various errors (problems I've read about in older threads), but once stable it would work without issues for days.
Yesterday the macbook found and installed a new firmware update, and wow, all **** broke lose. The external screen won't run at 2650x1600 for more than a minute before blacking out or suffering major graphical errors. Ironically one of the key points in the firmware update is better support for external monitors...
It will run nice and stable mirrored at 1920x1200, but not at 2650x1600.
Is anyone else in a similar situation after the latest update?

  • Latest firmware update and startup problems

    Hi I have been reading all about this so-called firmware and its importance in keeping updated on my new macbook pro. Therefore I have been diligently trying to keep it updated over my dial-up connection. I installed the latest firmware as my automatic update suggested. Now I get the spinning startup circle of death. Tried booting in safe mode to no avail. Help? (I also have version cue installed.)

    Hi jbell,
    Firmware updates are not availible in Software Update, only sofware updates are. Did you Repair Permissions prior to and after updating software? You always should. Go to Applications-Utilities-Disk Utility, and highlight Mac OS X in the left hand column, then Repair Permissions below. Firmware updates are available here....

    I have an iphone 4 with latest software update.  When entering the settings for bluetooth it continues to search for devices.  It does not highlight any device, just continuous searching

    Hello:
    What are you trying to do?  If you do not wish to connect to other BT devices, turn BT off.

  • Latest security update and the disappearance of my external drive

    I'm sure you're going to tell me that one has nothing to do with the other, but after running the latest security update, the Iomega MiniMax external drive that's been connected to my TiBook for the last 3 years has all of a sudden disappeared from my desktop.
    System profiler sees it, Disk Utilities sees it. But there are a couple of things bugging me:
    - I'd never paid attention before, but both the System profiler and DU indicated that SMART is not supported
    - When I ran DU (off the OSX install disk) to try to repair the HD, I got the following message:
    +Invalid node structre+
    +Volume check failed+
    (these 2 lines in red type)
    +Error: The underlying task reported failure on exit+
    (this in bold, red type)
    +1 HFS volume checked+
    +1 volume could not be repaired because of an error+
    I think that was in red, too, but can't swear to it, as I'm totally rattled by now.
    Now, there is no system on the Iomega, nothing but precious photos and music (since the original HD on this TiBook could only hold 30 Gb), and I'm at a loss as to why all of a sudden I can't access it. Whenever I've come back from a trip, I just plug the external back in (via firewire and usb), and it would just show up, as if nothing had happened.
    Any ideas, any help would be, as usual, most appreciated.
    Thank you all.

    I realize I'm getting 'way off this thread, but wanted to post back. I brought the Iomega to work, plugged it into my iMac and… nothing. Running DU gave me the same results as posted above. Then, for want of a better idea, I pulled out the install disk for the iMac, started up off that and ran DU.
    Guess what? It went through its verifications, came up with problems and then proceeded to repair the external. And that wonderful little orange icon was there on my desktop at startup!
    There shouldn't be any difference; my guess is it just happened to pick that time to mount. Sometimes a HD with issues will not mount 10+ times in a row, then, for whatever reason, it does on the eleventh try.
    There's a new folder in the Iomega now, called "lost+found", weighing in at a little over a Mb and full of files ending with ".nib". Any idea what those are and if I need to keep them?
    Hmmm, Google search turns up this from wiki:
    Interface Builder is a software development application for Apple's Mac OS X operating system. It is part of Xcode (formerly Project Builder), the Apple Developer Connection developer's toolset. Interface Builder allows Cocoa and Carbon developers to create interfaces for applications using a graphical user interface. The resulting interface is stored as a .nib file, short for NeXT Interface Builder, or more recently, as a .xib file.
    Do you use Xcode?
    Another hit mentions iPhone, and another Corel. Don't know what to make of it in your case. Can you open any of the files? Any have same name as your data? Creation dates?
    I shall now proceed to back up before reformatting.
    Good plan.
    And check out the cost of a replacement here (they're a good bit higher than in the States.
    Ask yourself what your data is worth, and after it's gone, what you would have spent to have retained it. My guess is the answer would be a lot more than the cost of a HD.
    Do I want a SATA?
    Nope, TiBook doesn't have that interface.
    I liked this model because it also worked as a hub… There are so many flavors out there now!
    Indeed.
    er, ahem, that's a sheepish "yes".
    'Nuff said.
    A while back, thanks to you and other forum members, I'd gathered up the courage to swap out the original HD for the biggest one the PB could take, and had always meant to to a "backward" backup of the stuff that was on the external — or copying photos onto CDs. Needless to say, the task got put off until this scare. Won't be doing that again.
    I considered myself "lucky" the first time I lost data, as it wasn't too, too important, but it taught me a lesson I've never forgotten.
    So, once again, thanks for the hand-holding (you had also talked me through/encouraged me to deal with the tight hinges on the TiBook).
    You're welcome. Together with RAM and HD, that was the best thing I ever did for my TiBook.
    Love this forum!

  • More and more problems with Quicktime!

    With the previous QT update, I lost the ability to change export settings for sound: I'm stuck on AAC, sample rate 11.025 kHz, Stereo.
    With the most recent QT update, I can't export at all! I get error message "Failed: Export process terminated unexpectedly (10)."
    Any help? Can I reinstall QT and start afresh?

    You might try resetting the PMU or SMU button on that machine. I believe the instructions to do this are in your owner's manual... what it does is reset the power management system wideand more... I've seen this fix fussy Firewire busses and make things work again with drives or camera/deck problems.
    There are tech articles about this on the apple site, but you need to search for your particular flavor of mac to get the instructions as to where this button is on different models. some Macs have SMU and some have PMU... but essentially I think they do much the same thing when reset. It's easy once you know how to do it...

  • FCPX and speed problems with new external hard drive

    Hi All,
    I have just bought a new Thunderbolt drive.   I created a very large disk image partition to separate my fcpx files from other iTunes type files - but strangely FCPX is now operating slower than it ever did when I was using 800 firewire.
    Any thoughts on why this might be the case?  I have encryption on the disk image (but it is the minimum amount). 
    Also - FCPX hangs regularly (when I go to Finder it states that the app is not responding) but then after 1 min, is back.   The whole environment is now less stable than when i was simply using  a 800 firewire drive with a disk image.
    All OS and FCPX is up to date.
    Any suggestions/comments appreciated.
    Best,
    R

    Hi Jim,
    Thanks for the tip.  I ran the app (quite a nifty app at that) and my speed tests for the main drive are Read 133 mbps and Write 137 mbps.  Which is not as high as I would expect for a Thunderbolt drive - does this sound right?
    Anyhow, I ran the same test on the Disk Image. And something is definitely wrong.  Read 1.4 mbps and Write 1.5 mbps
    Now I am scratching my head about this hard drive.   It is a single partition - nothing fancy.  Only this large Disk Image that is for media.  Any suggestions greatly appreciated.
    Best,
    R

  • Problem with HDMI - external display resolution (MacBook andSamsung HDTV)

    I just bought a new MacBook, and I have used my Samsung HDTV (http://www.amazon.com/Samsung-LN-S2338W-widescreen-720p-HDTV/dp/B000G6300U) with my old MacBook for over a year. First I tried to connect the two using the Mini Display Port to VGA adapter, which wasn't recognized by the Samsung. Now i tried using the Mini Display Port-->DVI-->HDMI route. The problem I have is that, while all the resolutions show up as able to be used in the display preferences (all the way up to 1920 x 1080), when I click on any resolution for the Samsung that is over 1280x960, all windows and dialogue boxes displayed on the samsung screen are jumpy, shaky and hazy. Is there anything I can do to allow me to use my preferred resolution of 1600x900?

    I'm no expert on this, but seeing as your TV has an actual resolution of 1280x720 (according to the link), I can't see how you'd get good results from anything higher than that.

    Java 6 you can't as Apple maintains it, and Java 7 you could if you uninstall it and Oracle provides the earlier version which they likely won't his last update fixed 37 remote exploits.

  • Attempted Iphone 4 update to latest firmware update "failed"

    Ive attempted to update the Iphone to the latest firmware update  and it has failed 3 times, the final time it looked as though
    it worked but stopped and went into new mode to go-back to Restore to old  setting. Now it is locked up and asking me for the  admin backup password
    and everything I've tried is not working..  Not sure what to do at this point.
    The laptop I'm using is a Panasonic CF29 and running Windows XP with SP3 installed.
    I'm  open to any ideas at this point.
                Thanks Artman

    Then it's pretty hopeless. Normally the error message remains displayed until you click "OK", so it's surprising that you didn't see it. You can try the shotgun approach; just try a bunch of stuff in the hopes that it will work. But first I suggest trying to update it again, and this time watch it. The following list covers the most common causes of update failures:
    Open a Command window and type the command "netsh   winsock   reset"
    Reboot your computer
    Disable your antivirus and firewall
    Launch iTunes
    Connect the phone using a USB port directly on the computer, not a hub
    When the phone is recognized in iTunes click on it, then click Restore
    If the phone is NOT recognized in iTunes, disconnect it, the hold the HOME and SLEEP buttons for exactly 10 seconds until the screen goes black, then release SLEEP but continue holding HOME while you connect the cable and continue holding HOME until iTunes recognizes a phone in recovery mode
    If the update completes you are in business
    You mentioned being prompted for a backup password. If your backup is encrypted you will need to know the password to complete the restore; if you don't know it you will have to restore as New and manually add your content back. If it is encrypted you really did enter a password for it once, whether you remember doing so or not.

  • Mid 2006 iMac Boot Problem (Since latest firmware update)

    I have a Mid 2006 17" iMac. Ever since the latest firmware update in early December, about every other startup I've been having boot problems. After the white screen with the Apple Logo and the spinning wheel it goes to a blue screen like normal, but instead of the 'Loading Mac OS X' white window popping up it stays blue and the spinning loading wheel starts. I've left it loading for quite a while before and nothing changes. I have to do a force shut off by holding the power button. and then I start it up and it will boot normally.
    Any help would be appreciated.
    Thanks!

    Actually, I think it'san early 2006.

  • With the latest flash update and on firefox 13 when I scroll on pages with youtube videos or other flash content it become corrupted.

    This does not occur with other browsers with the latest flash update.
    The problem also shows up even with add-ons disabled and testing it with a new profile.
    Does anybody have an idea with how to fix this, or is it a problem on adobe's end?

    I've fixed the problem by installing the older version of Flash Player (v11.2.202.235).
    - First, download the uninstaller from [http://helpx.adobe.com/flash-player/kb/uninstall-flash-player-windows.html here].
    - Close your browser(s).
    - Run uninstaller and remove flash player.
    - After the uninstall process, download and install the old version from [http://www.oldapps.com/flash_player.php here].
    Note: Download "Adobe Flash Player 11.2.202.235 (Non-IE)" if you are using 32 bit OS
    Or
    Download "Adobe Flash Player 11.2.202.235 (x64) (Non-IE)" for 64 bit OS.

    It's possible that you need new drivers from HP, in order to be compatible with OS X 10.8.3. Looking at HP website, they haven't released new drivers since last November. You might need to wait for new drivers or contact HP to push for an update.
