Firewire Driver issue

Anyone using M-Audio Firewire 1814 still experiencing Driver issues with Snow Leopard and LP9? There was an update on 11/13 and 11/14 but my Firewire still isn't working. Anyone got any ideas? This is absolutely crazy that M-Audio hasn't got itself organized. Make me think twice about purchasing another one of their pieces of equipment. This is crap!!

Thanks guys for replying - I'm very grateful.
I have reset PRAM, bought a new FW cable, de-installed and reinstalled OS X and APOGEE user interface. I do not have any other FW devices unfortunately but I can try it on  friends so will do that to rule out a hardware fault. The mini has only been in my possession since early jan and it was a completely clean unit - no apps or software etc.
The one suggestion I do not follow above is the Partition startup or Mavericks start up - sorry.,...what does that mean ? I do have 2 500gb drives plus 2 external HDD so storage is no problem. I will also try the SMC suggestion as I don't think I followed those steps clearly last time.
Again, thanks for your time. wish me luck - all I want to do is play and record my music !!!

  • LaCie Ext Firewire drive issues... Strange voodoo...

    So this is kind of a mystery to me... and complicated... bear with me. I am running Mac OS 10.4.4 (Tiger) and I have a Bigger Disk LaCie Firewire 400/800 d2 drive. I ran a version of Tech Tool Pro that wasn't compatible with Tiger (I know - stupid). The result was a completely unrecognizable drive to the OS. Disk Utility wouldn't even initialize it at first. I had to start up from my Panther disc and run Disk utility there and zeroed the data on the drive after recovering the data.
    Now everything seemed to be peachy however, every so often, usually when I am running an application that requires the drives attention whether it be Pro Tools, iTunes, Garageband - basically any app that needs to access the drive from time to time, forces the drive to not only freeze that application, but also freezes the Finder and makes it impossible for me to restart or do anything until I literally turn the drive off. The I get the usual device removal dialogue and everything returns to normal. Force Quit does not work in this case. I literally cannot get any application affected by the drives stalling to to Force Quit until I turn the thing off.
    Then when I run Disk Utility or Disk Warrior (I wont let Tech Tool do anything now) it reports that there is nothing wrong with the drive. In addition, in the Disk Utility S.M.A.R.T. status it says that is "Not Supported" when I could have sworn that before I reinitialized the disc it would always say "Verified."
    In order to perhaps help the problem I have diabled Hard Disk spindown as well as turned off Spotlight for that drive. I disabled spindown because it seemed that when the drive would go to spindown that it would freeze the Finder then too.
    Could it be extreme fragmentation that is causing the problem? There are no weird clicks or mechanical sounds coming from the drive. The only thing that occurs is the blue light on the drive blinks continuously - when it does that and I get the beach ball of death I know I am screwed.
    So sorry for the long post but if anyone could help me with this problem I figure they would have to have the whole story.
    Unfortunately I am leaning towards the dying drive theory - it would be the third drive to die on me this year alone.
    Any and all help is much appreciated.

    Hi Andrew
    Firstly I don't believe the S.M.A.R.T. status will show anything other than "Not Supported" because FireWire drives are not supported - only internal drives.
    Secondly your description makes me think there may be something wrong with the power supply (not exactly unheard of with LaCie drives). However I am not 100% sure - but it may still be worth checking out even if it is just to eliminate the possibility.

  • Firewire drive issue

    Not certain if this is the right place to post this. Sorry if it's not.
    The ext drive was working great until the wildfires chased us out. Now when I set it up, it's lighting up but I can't access it. I don't have the same config of ext's but why would that matter? Does firewire need to be terminated? My hard drive used to live with the cam attached and that's not on there. Should that matter? What am I missing here?
    Thanks for reading my miserable post.

    Thought you could use this info about getting FireWire to work!
    First, you should always Repair Permissions in Disk Utility before and after any update; I would do that now. If you installed your update with FireWire plugged in, your Mac may not recognize it anymore.
    Try resetting your FireWire ports by disconnecting all FW devices, shut down your Mac and unplug it from AC power (wall socket) for 30 minutes. plug it back in and try FW.
    If that didn't work, download the combo update from this site (yours may be corrupt), not Software Update, disconnect all firewire + USB devices except keyboard + mouse, Repair Permissions, re-install update, Repair Permissions again + try. Yours is the 10.4.10 Combo update ( PPC, not for Intel systems). Others reading, download the Combo that applies to your system.
    If that still didn't get it Zap the PRAM. While restarting Mac hold down the following key combo Command-Option-P-R. Keep holding those keys down till you hear the second start-up chime, then release.
    For those of you with Macs that are not PowerBooks or iBooks, a bad internal battery can cause FireWire to not be recognized, so make sure it's good! Also, here is Apple doc.#88338 on getting FireWire to work.

  • Firewire Drive to Thunderbolt via Apple adapter speed issues.

    Hi,
    My old MBP recently died (plastic at the back started to melt) while doing lots of editing so have bought a new MBP Retina display. As it only has USB3 and Thunderbolt ports, I purchased the apple Firewire 800 to Thunderbolt adpater to connect the powered G-Tech G Drive which contains my live FCPX project files. Anyway this drive is now really slow compared to how it used to run on the old MBP. Also it seems to be constantly spinning with multiple drive accessses. Sometime FCPX stalls as the drive is too busy. I contacted  G-Tech and they say their drives do no support third party adapters and at present they have not come back with a solution. I have heard that unpowered FIrewire drives using the Apple adapter won't work as the Thunderbolt port does not supply enough power (only 7W).
    Does anyone have a solution to how to get more speed out of the G-Drive (It has Firewire 800,  eSATA and USB2 ports)   b) why it's constantly active. G-Tech thought that "It is possible that this adapter is constantly sending a signal causing the drive to keep spinning." c) I have never used eSATA, has any one had any experience with eSATA to Thunderbolt / USB3 adpaters?
    I don't really want to invest in a new and very expensive Thunderbolt drive having just outlayed the expense to make this emergency purchase of my new MBP but if there are no solutions then I'll have no choice. Any suggestions greatfully recieved.

    I believe this issue is caused by bad ground coupling between the two devices, some of the induced charge can spark between connectors in the thunderbolt port causing computer to basicly freeze.
    To solve this issue try touching the connectors outside metal part to your macbooks body first to discharge it, then while plugging int the connector do it at slight angle so the metal of the connector touches Mac's body.
    This method has been working for me.

  • ISight Firewire Hard Drive issues? Anyone?

    Hey there, I just picked up a refurbished 1.83 Core 2 Dou Mac Mini, and I've got a weird issue going on.
    The single Firewire port is giving me some greif - I've got a MyBook 500 gig FireWire drive plugged into the port. I've also got an iSight (and a bunch of other FireWire devices) but I seem to have issues chaining them.
    When I plug the iSight into the second FireWire port of the drive, it isn't happy. I get a really distored picture, interlaced fields, and it runs at about 1 frame every 3 seconds. Then it crashes iChat, or the screen previewing the iSight image goes gray and tells me the "camera is being used by another application".
    When I plug the iSight in directly, it works great.
    I read some of the other posts and it sounded like it might be a power issue, so I bought a Belkin powered 6 port FireWire hub (I've got a 3G iPod I also need to plug in, and a external dual layer burner, and my FireWire camera, so I needed one anyhow).
    Still having the problem! When the iSight is on the same chain as another device, it freaks out. If it's the only device in port, everything is fine.
    Anyone else having or had this problem?
    Thanks!

    Hi RocketChicken-
    Greetings and welcome to the Apple boards.
    iSight cameras are notorious for being picky about what else is connected to the FW bus. Does it cause problems just being plugged in or only when it is on?
    You may find more help in the iSight forum: Forum : iSight

  • Firewire external hard drive issue with 10.9.3

    Hello,
    i have got a question to the existing firewire bug in Mavericks! My thought was, that with 10.9.3 all would be better, but that´s not true.
    My Firewire drive does not spin down for sleep, when my iMac goes to sleep. Does anyone know, if there is a solution or, better, when there would be
    a solution? - I do have to downgrade my Mac, if there is no better solution than unplugging the drive. It´s enough annoying, that my printer and my scanner do not work properly. But unplugging the drive everytime i leave, would then be my "cherry on the cake" which brings me to the question, why i have a mac?!
    I tought windows is the only system, that is compounded by its own updates and upgrades ...
    Thanks so far!

    Have you tried opening your project through your external hard drive.  Go into it, open the file Final Cut Projects
    and double click your project.  It should launch it.
    I also use an external hardrive and that is what I did.  Has been fine ever since. 
    Final Cut Pro X on the other hand is so slow that is is not even usable.  I get the spinning beach ball if I even try and move my cursor!!!

  • Firewire drive no longer recognized after upgrade?

    having an onset of problems the last 2 weeks.
    first upgraded to 10.4.6 on mac mini 1.42 non-duo, worked a few days than acted weird with apps crashing. had to reinstall from 10.4 disk. seemed ok. repaired permissions, ect. after reinstall (and a subsequent power outage) a firewire drive attached at time was no longer recognized by mac mini or connected imacG3. reinstalled 10.4.2 on mac mini. installer unable to reinstall 10.4.6., I would like to have firewire drive recognized again. when attached to other firewire drive in daisy chain, says device unrecognized, other wise unable to get any info on drive. what to do?

    I am having nearly the exact same issue as you are experiencing. My Western Digital Dual-Option Media Center 160 GB FW HD is going in and out big time. It seems to be there for a time but then conks out. I have to disconnect the power and now the drive seems to be malfunctioning.
    Same story with my LaCie 52x CD Burner. I placed the Disk Warrior CD in there and the computer recognized the disc at first but then spinning beach balls galore!
    This has to be one of the worst updates to an OS X system I can remember. I can only think PowerPC QA testing has gone through the toilet since the Intel move was completed.

  • Incredibly slow MacBook, Internal Hard Drive issues...

    Good morning everybody! I'm apologize if this post is extremely wordy...
    I am extremely baffled by a particular issue with a MacBook 2.0GHz C2D which belongs to a friend of mine. The warranty is expired.
    _Brief history:_
    Several months ago, this MacBook could not find a bootable volume. The drive would not mount when booting from an external FireWire hard drive. It would not mount when the MacBook was put in Target Disk Mode and connected to another Mac. When booting from an external USB hard drive or with my MacBook Pro connected to the MacBook via Target Disk Mode, the MacBook booted up quickly. I came to the conclusion that the internal hard drive must have failed and needed to be replaced. Ultimately, the data was not recoverable from this drive.
    I then proceeded to swap out the defective Apple OEM Seagate hard drive with a known working Apple OEM Fujitsu hard drive. When booting from the Leopard Install DVD, the MacBook would boot incredibly slow, but would finally reach the Installer Language screen. When proceeding to install Leopard, the drive would take a very long time to have data written to it, and ultimately the install failed. I removed the new hard drive from the MacBook and placed it in an external USB enclosure, attached it to the MacBook and booted from the Leopard Install DVD. Leopard would install successfully. I removed the hard drive from the enclosure and reinstalled it the MacBook. When booting from the freshly installed OS, the MacBook would take a very long time to boot. The MacBook is extremely slow!!!
    I checked the Activity Monitor to ensure CPU & System Memory Usage was not going crazy. All Processes where normal with adequate CPU & Memory headroom.
    I took the MacBook apart thinking that the SATA Controller Cable might be loose. No, it was firmly in place. I reassembled the MacBook and booted it up again. Still incredibly slow!
    Finally, after several reboot attempts, the MacBook would book up quickly and operation was perfect. I applied all updates and continued testing the MacBook with great success. Gave my friend his MacBook back and he was grateful.
    _Now for the kicker..._
    My friend brought me his MacBook a week ago complaining that the MacBook was operating extremely slow (much like when I was initially testing it before). I verified the MacBook was slow when I tried using it. I tried several reboots and then it would get stuck on the gray Apple with spinning gear.
    I tried booting into Single User Mode, but it gets stuck on "Waiting for root device"
    I put the MacBook in Target Disk Mode and connected it to my G5 2.0GHz Dual Core. The hard drive would mount quickly on the G5 and I used Disk Utility to create a Restore Image. The disk operation would perform normally and the image would be created successfully.
    I then partitioned the MacBook's hard drive when connected to the G5, ejected and proceeded to attempt OS reinstall. No dice! The hard drive is not even detected by the Disk Utility on the Leopard Install DVD.
    Finally after several reattempts, the hard drive is recognized, but is extremely slow when trying to reinstall...and again, ultimately install fails. Using Disk Utility from Leopard Install DVD, the hard drive fails to unmount when I try formatting.
    I don't have Apple Hardware Test disc for the MacBook or Apple Service Diagnostics disc for this model. Running TechTool Pro shows hardware to be okay, disk controller onboard the Fujitsu drive is okay, but running SMART & Surface Scan takes a long, long time (which I'm certain will ultimately error out). Running Drive Genius takes a long, long time as well.
    Conclusion:
    I think the SATA Controller Cable is defective. I can't think of anything else that would cause disk errors or performance issues like this. Your input is truly appreciated!

    Even though no one responded to my post, I thought I'd share the resolution with the entire Apple community. I hope this information will be helpful to some of you with MacBooks or MacBook Pros that may be running painfully slow or may be exhibiting hard drive issues because your machine won't recognize the boot drive or fails to properly boot on a perfectly healthy S.M.A.R.T. verified hard drive. It just might be the hard drive connector/cable. Here it goes...
    I visited my local Apple Retail Store and asked a "Genius" at the Genius Bar about this issue and told him my thoughts about a possible failed hard drive connector/cable. First, he didn't even know what a hard drive connector was! Then, he arrogantly stated that he never heard of such a thing and that these cables never fail. Finally, he blatantly dispelled this as a possibility.
    On the contrary with my experience, I have had many failed PATA controller cables that required replacement when supporting the desktop PC's at work. I have personally owned and supported many Apple manufactured laptops and desktops and have never encountered this issue on a Mac...until this MacBook!
    So, after looking at the Service Manual for the MacBook, I went over to my local Apple Authorized Service Provider and purchased the Hard Drive Connector Apple Part #922-7579. I replaced the original cable, reassembled and proceeded to boot the MacBook with the Leopard DVD installer. The Fujitsu drive was immediately recognized and was able to be formatted and Leopard installed without incident. The MacBook boots off the internal hard drive as normal again and works nice and fast again.
    Thank you all for your time!
    :D

  • My Book 500 GB ext firewire drive not compatible with osx 10.3.9???

    When apple support immediately blames other companies for problems and at the same time refuses to help me get osx booting on an external hard drive just because apple didn't make the external device, it sure sounds like microsoft's slimy politics. Should I stop buying macs because they won't boot off an external hard drive because apple support won't help?
    I tried copying my current osx with diskutil (an apple product). When I try to boot off it, I get a square with a ? then the finder icon, then it boots off the internal hard drive. Surely its a problem with diskutil (an apple product)!
    I have no problems booting off my internal drive so I know the os is good. I ran disk util and it reported errors which disk util couldn't fix but disk warrier said it fixed... OMG!
    Funny thing is... it reported different errors on the 2 drives (one a copy of the other). Tried using carbon copy clone which always worked before. It refuses to boot of the my book drive. I have leopard on a second external drive which boots normally. So what is wrong with the 500gb My book drive or osx? It is a firewire drive so it should boot. It had no problem installing a dozen times osx 10.3.9 & 10.3.5 but still get the same ? and finder icons before booting internally.
    Tried to get help from WD (drive maker). No luck after the 4th try so I'm zeroing the drive and taking it back.
    Unless I can get it working tomorrow... somehow... without apple support....?
    And I bought the drive so I could use Time Machine! (another apple product). No support there either...
    Should I just turf the drive and stop buying macs?

    Thanks for the quick response. I didn't bother to check what format it had. Just reformatted it for mac.
    Yes, I ran the disk partion in diskutil and split it into 2 partitions. Didn't make any difference with the boot problem because when I set it back to one partion and installed 10.3.5 off the dvd, it still had the same ? finder icon issue. So I doubt it was a partition issue.
    So I did format it hfs+ and used the partition tab in disk util. So that's why I don't understand why it is suddenly a problem as I had no issue cloning drives to my other ext. hard drive.
    At first I thought it might be an issue with the bootable partition not being the first one listed. But that didn't make a difference when I changed the order. Usually I just run carbon copy cloner and make a bootable copy but that didn't work either. Tried installing from the dvd, that didn't work either. So I'm at a loss to explain why its such a nightmare to make a bootable backup.
    The working copy on my internal hard drive runs just fine even with/without errors. Surely a cloned copy should also work as it has in the past.
    Basically, I wanted to clone my internal hd to an external one so I can move my leopard os on another ext hd and put it on my internal drive.
    Right now I have panther on my ibook drive and leopard on my ext hd. I'd rather have it the other way around since the leopard patches seem to have fixed things.
    On my panther drive I have vp7 and xp installed. Whether that makes a difference, who knows?

  • Cannot Boot from OSX on external firewire drive

    I recently bought a seagate hardrive and installed it in an external firewire casing. I partitioned it into two partitions, and installed osx 10.4.10 on one of the partitions, the same as is running on my Ti Book.
    I tried selecting the os on the firewire drive as the startup disk, but when i restart, after the grey screen i get the flashing question mark icon, until the mac recognises only the default osx on the internal drive and boots with that instead.
    That not working, i created a clone of my startup disk using DejaVu in my system preferences and saved it on the other, empty partition on the external drive and tried booting from that.
    On restarting, i get the grey screen once again as the backlight fires up, and nothing more. the screen remains grey without any further ado until i hold the power button and force it to turn off. then as i start it up again, up comes the flashing question mark icon followed by a boot from the internal drive.
    Any Solutions on this?
    Many Thanks, Neptune.

    Hi Dale,
    Whoops- everythings not as smooth as i thought it was!
    since i restored my internal drive, a lot of things have been really messed up, starting with, for example, iTunes reverting to version 4 instead of 7. that wasnt a problem, i still had the 7 installer, and soon had my whole music library back again. but the computer appears to have a problem with the handling of graphics. the finder wont create previews of even simple jpeg images, nor will it for video. quicktime wont open any video file, i get some random error message which i cant remember stating it could not open the file. and if i view my finder window in grid icon view, the usual blue mac os desktop image that i keep as a background in the finder window isnt there, instead its pitch black. same goes for the slideshow feature in the application graphic converter, i can start a slideshow and it will scroll through the images, but every image will instead be completely black. there are no scroll bars in itunes. i can scroll down randomly by clicking where the scroll bar should be, but there is nothing visual there at all, no scroll bar, no arrows. when i connect my ipod, the main ipod window of itunes wont display any graphics either, be it the picture of the ipod or the capacity bar indicating usage of the drive for music, videos, data, etc. instead, fine print says something similar to 'cannot display image, quicktime and lzw tiff decompression plugin (?) required' I cant remember word for word what it says, dont quote me on that.
    the computer also came to a dead freeze twice in ten minutes, i had to hold the power button down to get it to shut off.
    im sure there are other issues too which i havent yet noticed, but even these, i havent the faintest clue what could be causing them!
    do you?

  • External Firewire drive does not mount on desktop now.

    Greetings everyone.
    G5 dual, 4.6GB ram, OSX 10.4.10, external firewire drive, formerly worked fine, now is invisible.
    Not the drive. New purchase, worked fine until a restart. Not the cable. Power is getting from the G5 to the firewire drive. Not the port. I also have a firewire card instlaled so I have three ports to connect it to (and two on the FW drive). No combination works. Not the computer, the FW drive also fails to appear on an iBook. Not the OS. I did a clean install to make sure.
    I'm not a newbie. I know what I'm doing. Until now! DiskWarrior, TechTool Pro, Drive Genius and Apple's Disk Utility cannot see the drive.
    The FW drive is a Powerbook internal HD inserted into a case, purchased seperately.
    At my wits' end. Can anyone help please.

    I am suddenly having this EXACT problem. I have two Firelite firewire drives (one 60G and one 80G) that are suddenly refusing to mount on my older dual 1.25GHz G4 tower. They are also suddenly refusing to mount on my non-intel iMac. They will both mount painlessly on my new Intel MacBook Pro, but that's not much use, since the point of the firewire drives is to transfer files between these computers. I'm updating all of them to 10.4.10 to see if that's the issue...

  • Time Machine on FireWire drive not recognized

    Got an iMac with a FireWire drive set up as a TimeMachine volume.
    In addition, I have a MBP, connected to the network via Wifi (Airport Extreme).
    Under Snow Leopard, both Macs were able to do TimeMachine updates to the FireWire drive connected to the iMac.
    Now, under Lion, the TimeMachine volume is still recognized and functional (i.e. successful backup) for the iMac, but not visible anymore for the MBP.
    The MBP can't see the TimeMachine volume, let alone back up to it.
    What gives ?
    Is this perhaps a network or access authorization issue ?
    Thanks.

    Ok, so here some more information.
    iMac (Lion) with connected FW HD, thus hosts the TimeMachine volumes, connected via Ethernet to AirportExtreme
    MBP (Lion), connected via WLAN to AirportExtreme
    Connecting FROM iMac to MBP:
    Sidebar - Shared computers: OK
    Terminal SSH: OK
    Finder - Go - Connect to Server: OK
    Connecting FROM MBP to iMac:
    Sidebar - Shared computers: Error "Connection failed"
    Terminal SSH: OK
    Finder - Go - Connect to Server: Error "There was a problem connecting to the server"
    I'm really beginning to think my MBP Lion install is borked.

  • HELP! - Error 1309 - Can't copy file over 10gig to External firewire drive.

    I know this is more of a hardware issue but I know that only other final cut users would be copying single files over 10gigs.
    I have a G5 that I use for video production. Video Files can be large and to back them up I got an external hard drive ( Maxtor 1-touch 200gig) When I try to copy a file on to it that is 10gigs it give me a 1309 error. I have found that other people have had trouble copying files over 2gigs over to an external firewire drive. But I haven't found any answers. Can anyone offer any advice on how to solve this?
    Thanks

    If you don't want to format it for the mac, you are limited to file sizes under 2gb.
    Another alternative is to hook a firewire drive to your Mac and then share it with your windows machines (the program SHAREPOINTS is useful for this).
    The drive can then be formatted Mac OS Extended and, once shared, the PCs can access all files without size limitations.
    good luck.

  • How to boot from external firewire drive

    Apparently my internal HD on the powerbook has died as it repeatedly gives me the black screen "restart" message and re-install of system software fails.
    I have an external bootable firewire drive, which is a "carbon copy" of my iMac, however, it's SnowLeopard not Leopard, so is there any way I can use the firewire drive to boot off of on the G4 or any other suggestions?
    Also, does anyone know what Apple typically charges to replace the internal drive in the PB G4? I looked at the video for doing it myself and that is not an option for me.
    Thanks!

    The black screen restart message, or kernel panic, can be caused by a number of causes, most which are typically hardware-related, and many times a problem with memory. Try re-seating the memory to see if that makes a difference.
    This is a good read on kernel panics: http://www.thexlab.com/faqs/kernelpanics.html
    If you have the original OS X disks that came with the system, find the first one that should say 'AHT Version x.x' in small print on the label. Insert it and reboot while holding the alt/option key down. Choose the Apple hardware test, and when prompted, choose the extended test. That might give you some additional information on any hardware issue(s).
    You can't use your Snow Leopard bootable drive on the Powerbook, as Snow Leopard requires an Intel-based system.
    If it turns out it is a hard drive issue, be aware that Apple will keep your current hard drive as a trade in on a new drive. Some people have private data on the hard drive and have a concern with it leaving their ownership (even if the drive isn't working).

  • USB/FireWire Ports Issue

    So before I go into the apple store and ask for this computer to be repaired/replaced, I would like to see if anyone knows if something can be done about this issue I have pinpointed..
    Basically when I have more than a few USB/FireWire ports connected, one or more of the devices does not function properly. This has happened with two external hard drives - which should have no problem being connected simultaneously.. When I try to eject one of them, I receive a message stating that it cannot be ejected because one or more programs may be using it.. although all programs are closed, causing me to have to force eject..
    Also, I plug in one drive and open the other in finder to back it up, and all of the folders in the drive are suddenly empty.. nothing inside. I go to Get Info.. Zero KB.. I try ejecting, but receive the same message, so I force eject, plug it back in, and wala, all the files are back in the right place..
    This has also happened in the past when my cinema display and a printer were plugged in simultaneously.. the computer won't detect the USB of the cinema display -- which only means that the speakers of the display won't work + no brightness control from the keyboard.. so i let it slide.. but now with this external hard drive issue, i need to solve the problem..
    Thank you for reading..

    Same here. Since a few weeks, my MacPro ejects USB HDD's as soon as I write or read data on it.
    (no I haven't installed something new at this time and all HUB's and HDD's have their own power supply, and yes they have been exchanged, so its not a broken cable or so !!!!!!!!)
    After a reset of the NVRAM and PRAM its better for an hour or so, then starts to eject again.  I've seen a lot of communities with exact the same question, but never a solution for it. There is also nothing in the support tab of apple.
    Hope someone here can help me out or due to the fact that this is a AplleSupportCommunity, a Apple-Employee may starts to do his job and help this huge amount (I guess there are hundrets or tousand) of mac-user with exact the same problem....
    btw: don't agree with MACATTACK2010 that this is a hardware problem, cause there are a lot of people in the
            net that ask the same question with brandnew Hardware. I think it's an OS or an Update Bug, or may both.
