USB Speaker/LED Cinema Display Problems After Upgrade to Mavericks

I just upgraded to Mavericks this morning.  My set-up includes a new (Late 2013) 27" iMac and a 27" Apple LED Cinema Display, with the mini display port and USB connected from the display to the iMac. 
I have a set of Bose USB speakers that I had plugged into the USB port on the Cinema Display for audio.  I didn't want to waste one of the USB 3 ports on the iMac so instead was using a USB 2 port on the Cinema Display.  This worked fine before upgrading to Mavericks.
Now with Mavericks installed, if I have the speakers plugged in, I get a tone that sounds like very loud feedback.  If I plug the USB speakers into one of the USB 3 ports on the iMac however, it works fine.
Does anyone know if this is a known issue with Mavericks?  I've read some other posts about display issues, but they were referencing USB displays.  In this case the display is connected via mini displayport, but the USB connection on the display seems to be causing issues.
Anyone else experienced this?

I've been experiencing additional issues with USB speakers. I plugged them into a USB port on the iMac itself (as opposed to the LED Cinema Display) and the feedback was gone.  However, now I get situations where the audio appears to randomly "die" on the system.  If I go into Audio preferences and switch the audio output to the internal speakers, the audio comes back on.  If I then switch it back to the USB speakers, it continues to work until it randomly dies again.  This happens typically 3-5 times a day.
If I just use the internal speakers as the audio output, I don't get any issues with losing the audio.  The USB speakers worked fine on the iMac before upgrading to Mavericks, and still work fine on my late 2011 MBP still running 10.8.5. 
I've read about other similar issues ( Still waiting for a fix.

  • Apple cinema Display problem after update

    I had a similar problem to lain Maclreud
    Immediately after updating to 10.4.11 and rebooting the toparea on my cinema display went dim and I saw the 2 short, one lon blinks on my power display LED
    I didn't try it on another computer yet or try to change my power source but I may need a new backlight card as well. Please post if you have had similar problems after updating and suggest possible solutions.

    Have you tried the Command-Option-P-R keys to reset the PRAM? (Maybe the upgrade has messed up the display settings?)

  • Display problem after upgrading MacBook Pro to Snow Leopard

    Immediately after upgrading my MacBook Pro to Snow Leopard OSX, the display has been exhibiting vertical gray 'banding' extending up from the bottom of the display.  Each band is about 1 inch wide.  The display seems dimmer as well, and I can't brighten it up.
    I'm in the process of upgrading to Lion (Snow Leopard was the intermediate step) and am hoping that resolves the problem. Any advice/suggestions?

    I do not have answers for you, but I'll be waiting to see if someone has a "fix" for this. I am running snow leopard on a MacBook Pro, and I have a dim screen problem that doesn't brighten also. (no lines in mine, though)

  • Cannot  set display resolution after upgrading to Mavericks

    I have early Mac Mini  connected to KVM stitch.  Over the weekend I upgraded to Mavericks and it "dowgraded" display resolution from 1920x1200 to 1600x1200 and everythign looks streached.  1920x1200  no longer shows on the list in display properties (1920x1440 shows but it does not look good on my screen). I googled Option key trick and hitting "Scaled" while hold Option key does show some additional resolutions, but not the one I used to have. 
    Connecting Mac directly to the monitor allowed me to set proper resolution and after removing monitor and pluging mac back into KVM things "held" untill Mac goes to sleep or until reboots.
    I am aware that my KVM switch does not communicate EDID but things did work just fine before upgrade to Mavericks.

    Hello curtdav,
    It sounds like you are getting a graphical anomoly when unplugging an external monitor. I recommend these troubleshooting steps from the article named:
    Apple computers: Troubleshooting issues with video on internal or external displays
    Reset the system
    You can reset the Mac's parameter RAM and SMC.
    Reset the resolution
    Start by resetting the Mac's parameter RAM. If the display does not come up, was previously set to an unsupported resolution, and still results in no video:
    Start up in Safe Mode.
    From the Apple () menu, choose System Preferences.
    Choose Displays from the View menu to open the preferences pane.
    Select any resolution and refresh rate that your display supports.
    Restart your computer.
    Thank you for using Apple Support Communities.
    Take care,

  • Computer problems after upgrading to Mavericks

    SO many problems. I cleared out a ton of old stuff that I saw might be causing problems, and I've verified and repaired the disc, and uninstalled and reinstalled a couple of programs that I was seeing problems with in the console, but now I'm just flummoxed. It's behaving better than it was earlier, and isn't giving me the beach ball nearly so often, but it still seems like it's taking too long for a lot of things. I just reinstalled Avast and am currently letting a game update through Steam. I have the console and the activity monitor open to one side. Since I opened the console, it's been spitting out one or two messages every second, and all I can find through some internet searching is that it's something to do with the wireless connection. There's some other stuff periodically mixed in that doesn't sound good either, involving either sandboxd or mdworker. But for the most part it's along these lines:

    I just reinstalled Avast
    "Avast" is perhaps the worst of the whole wretched lot of commercial "security" products for the Mac. It's worse than the imaginary "viruses" you were worried about when you installed it. Not only does it fail to protect you, it throws false warnings, destabilizes and slows down your computer, and sometimes or always corrupts the network settings and the permissions of files in your home folder. Removing it may not repair all the damage, and neither will Disk Utility or even reinstalling OS X.
    Back up all data, then remove "Avast" according to the developer's instructions. Reboot.
    If you tried to remove Avast by dragging an application to the Trash, you'll have to reinstall it and follow the instructions linked above.
    If you still have problems after following those instructions, post again.

  • Graphics display problem after upgrade of HTML DB from 1.5 to 1.6

    I recently installed HTML DB version 1.5 from Companion CD and tested and everything seemed to work. I immediatley applied the 1.6 version upgrade but now no graphics are shown on the HTML DB ADMIN page. I checked the files from the upgrade $ORACLE_HOME/Patch/htmldb/images and the $ORACLE_HOME/CCD/marvel/images and verified the Alias in $ORACLE_HOME/CCD/Apache/modplsql/conf/marvel.conf. Do I need to look elsewhere for the images?

    If that's the case then they made a mistake. If there's not a specific forum for HTMLDB, you could try one of the database groups because I think it ships with the database.

  • Serial number problem after upgrade to Mavericks

    My old CS5 Photoshop v. 12.0.4 works fine in an old Mac computer with OSX Snow Leopard, but after transfer to a new Mac with OSX Mavericks whenever I try to open Photoshop it asks for a serial number I no longer have. Bought Photoshop years ago, never registered it because I only had dialup internet in those days (and my rural DSL line still crawls at 1.5 speed), install discs and box are nowhere to be found and I don't want to upgrade to a newer version. Just want to use my old Photoshop like I did before, without Cloud or any other nonsense. Can I I get a new serial number or how do I activate it?

    If you lost your serial number, your proof of purchase and also failed to register your product, there's not a lot we can do for you. Sorry.
    If, however, you lost your serial # but have the product installed and activated using a genuine serial # you can launch Photoshop and select Help>Product Registration... to register the serial # with your Adobe ID. You can then log into your Adobe account on to retrieve your serial #. (Note: It takes about 5-10 minutes for the serial to show up in your My Products of your Adobe account when you register this way)
    Other purchased products: From within your product, choose Help > Product Registration. (You don’t need to have your serial number when you use this option.)

  • Thunderbolt Display has issue with weird washed-out colors after waking from sleep (after upgrade to Mavericks)

    I've got a Thunderbolt Display that I use with my Macbook Air (mid 2012) - usually in clamshell mode.
    When I let the computer go to sleep, and then wake it up by clicking the mouse, the monitor turns back on but the colors are washed out and purple looking. 
    The display goes back to normal when I unplug and replug it to my laptop.
    I first noticed this problem after upgrading to Mavericks.
    I made a video demonstrating the issue here:
    Any ideas?

    Same thing for me too.  Late 2012 13" MBP Retina.  I have to unplug the Thunderbolt cable and plug it back in.
    This has only started for me in the last two days.  The first two weeks of Mavericks was ok.
    Update:  I just got back from a trip.  I was using the laptop separate from the Thunderbolt display.  I hadn't restarted since I returned and connected the monitor.  I've just rebooted, and put the computer to sleep.  After resuming from sleep, the display is ok.  Maybe try rebooting?  I'll update if it continues.

  • Apple  LED Cinema Display -- USB Port + iSight Camera not  working

    I see an unusual problem with my brand new LED Cinema display. When i put my Macbook pro in sleep mode it deactivate all the USB ports and isight camera in LED Cinema Display. When I turn the computer back on I cannot use USB or iSight camera. I tried below solutions -
    - Restarting the Macbook pro and LED cinema
    - Completely draining the power in both LED Cinema and Mackbook pro.
    - Resetting Macbook pro.
    - Upgrading LED Cinema to latest and greatest firmware ( firmware update 1.0)
    Did anyone encounter this problem ? If yes please post your thoughts or any solutions.

    After numerous attempts of powering down/resetting the macbook pro and led cinema i was able to make the USB ports work. However I was able to successfully reproduce the problem once again by putting the mackbook on sleep mode.
    I finally ended up shipping my led cinema back to apple for a replacement. I will try the test case with the new one when it arrives.

  • LED Cinema Display 27 Random Loss of USB

    I have a brand new 27" LED Cinema display connected via Mini Display Port to my 2006 Mac Pro with an ATI Radeon HD 5770 graphics card.  The display's USB cable is connected to a USB port on the back of the Mac Pro.  My keyboard is the newest Apple extended keyboard (wired) that is plugged into the back of the monitor.
    The problem is that randomly (about one out every 8 boots but with no pattern or rhyme-or-reason), I have no USB connectivity from the keyboard.  I am unable to enter my user name and password to log in.  While it is in this state I have pulled the monitor's USB cable from the back of the Mac Pro, waited 15 seconds or so and then plugged it back in.  This does not fix the problem.  The only solution so far is to force shut down the computer using the power button on the front of the Mac Pro, then disconnect the monitor's power cable, plug the monitor's power cable back in and re-boot.  So far 100% success with this process.  Somehow removing power from the monitor resets its USB bus.  I just don't think I should have to do this once or twice a week... or more.
    So I have a solution but it is a pain in the rear and involves crawling under my desk.  I could try plugging the keyboard directly into the Mac Pro and abandon all use of the USB ports on the back of the monitor but would hate to give up functionality that I paid for.
    This only occurs on boot... I have never lost USB connectivity while the computer is running if it boots and works properly... even after sleep.
    Any thoughts or help would be appreciated.

    I installed Mountain Lion last night. Playing around a bit before going to bed I noticed that my keyboard seemed to fade in and out, sometimes what I typed showed up, sometimes not. This morning I was using Messages, tried the camera. First I got a warning saying no camera was attached to Mac (built in iSight?!?!?!). The unplug/plug method didn't address this. Restarted Mac Pro, camera showed up but there was major lag, like it was someone's video sent to me from a bad connection not locally streaming video! Also, graphical anomalies kept popping up in the video. (a note: none of this was happening with my MBP with FaceTime camera after ML install)
    And then it hit me.
    Due to the short span of the mini display cable on the LED Display, I have to use an extension cord for the MiniDisplay and USB. Removing the MiniDisplay extension cured my video issues. I removed the USB extension and put in place another USB hub testing my previous post. So far, with keyboard and Wacom plugged into the Displays USB, no issues. It's early though so who knows. I wouldn't mind trying a straight connection to a Mac Pro USB but Apple has made the cable far too short and working with my head next to the tower just isn't desired.
