Wired Keyboard issues with Flash / general slowness with LION

So I upgraded to Lion about a month or so ago.  All has not been great.  I am running a 2009 Dual Core Intel iMac with 3 GB ram.  One thing I notice is that initially certain flash support was NOT supported (mainly web cam support through flash on web sites).  So web sites offering chat clients with cam support as an example - the performance would lag badly where typing messages would skip letters and leave nothing but garble.  I attempted to try different browsers, but found the results to be disappointing:
Safari:  Web cam support through web sites was simply broken - even manually trying to alter adobe settings would not get you any further
Firefox 5:  You had to set permissions for web cam support prior to launching a web site as flash settings to enable / disable it within the web site were simply not useable
Chrome:  Settings worked, but the performance was so slow, if using a web chat client and a web cam at the same time, it was almost impossible to type proper words unless you typed a character a minute.
I realize there has been a Lion update recently (a few weeks ago) and after the update, most of these issues seemed to be fixed.  But then, Adobe came out with a FLASH update and now performance is lagging once again to the point where web cam and chat is almost not useable.
Is there anything that can be done to work around this issue?

  • I have an Apple pro wired keyboard that I want to use with a Windows PC.  It seems to recognize it through plug

    I have an Apple pro wired keyboard that I want to use with a Windows PC.  It seems to recognize it through plug & play, but stops working after a few minutes.  Does anyone know of a fix to this situation?

    Hi,
    Could you explain that again using different words ?
    I am not clear on what it is that you want to do.
    What are you trying to sync ?
    Contacts ?
    Emails ?
    Other info ?
    If it is Mail who do you normally get it and what applications are you using ?
    People also might want to know if it is a POP or IMAP account before they can help.

  • White screen with flashing file icon with question mark mean

    What does this mean.   We are getting a white screen with flashing file icon with question mark inside the file. 

    It almost certainly means it can't find a bootable volume (one with OS X on it).
    Which means most likely you will have to find your original system installation DVD and install it. Then you should figure out what caused the problem.
    Read this to diagnose it before resorting to reinstalling the OS:
    http://support.apple.com/kb/TS1440
    Excerpt:
    Additional steps
    If your Mac still starts to a flashing question mark, follow the steps below. If any step resolves the issue, you don't need to continue to the next one.
    Select your Mac OS X startup disk with Startup Manager by restarting and holding the Option key. After your Mac starts up, restart again to verify that the flashing question mark does not appear.
    If the issue persists, insert your Mac OS X installation disc. Be sure to either use the disc that came with your Mac, or, if you installed a later Mac OS X version from disc, use the newer disc.
    MacBook Air note: On a MacBook Air, there are two options for starting up from Mac OS X media: Either connect a MacBook Air SuperDrive to the MacBook Air via the USB port and restart the computer, holding down the C key during startup, or use Remote Install Mac OS X to startup from a system software DVD that's located on a partner computer. Once started up from Mac OS X media, skip to step 3.
    Restart the computer, then hold the C key during startup.
    From the Utilities menu, choose Disk Utility. Don't click Continue.
    Select your Mac OS X disk (named "Macintosh HD" by default) in the left side of the Disk Utility window.
    Click the First Aid tab.
    Click Repair Disk to verify and repair any issues with your Mac OS X startup disk.
    After repairing the disk, try to start up normally.
    Important: If Disk Utility finds issues it cannot repair, you may need to back up as much of your data as possible (or use Time Machine to back up to a different disk), then erase the disk and reinstall Mac OS X. You should back up important files and data before erasing a drive. Erasing deletes everything on the hard disk (including things on your desktop). Also, you can install Mac OS X onto an external disk, start from the external disk, and use Migration Assistant to transfer items from your usual internal Mac OS X startup disk to the external disk, then erase the internal disk and reinstall Mac OS X.
    If the issue persists, and Disk Utility didn't find any irreparable issues, quit Disk Utility, quit the Installer, select your disk when prompted, and restart.
    If the issue continues, reset PRAM. Note: After resetting PRAM, if the computer starts up normally, reselect the startup disk in the Startup Disk preferences.
    If none of these steps resolve the issue, start up from the Mac OS X Installation disc and reinstall Mac OS X.

  • Keyboard issues while installing Windows XP with Bootcamp

    Hi there,
    I am running bootcamp and when I am starting to install Windows XP I can't actually move into the setup because the keyboard won't work. Is there anyone who found a solution?
    Thanks.

    Same problem..........went back to the old keyboard and everything installed and worked fine in OS X and win-XP. swapping in the new alum keyboard the option key doesn't work during the boot select. once the machine boots to the default OS either mac or windows everything works in that OS.
    Something I noticed: during the boot select.... the old keyboard gets power immediately, mouse lights up - keyboard cap-lock light is on. with the new alum keyboard the mouse and cap-lock light do not light until the default OS starts to boot with no boot select in between.
    Looks like a boot camp setup doesn't know about the new keyboard even though it is recoginized by drivers in the two OS's. anyone know who to call for help at Apple?

  • Baffling Apple Wired Keyboard Issue

    I have a new iMac (2012, 27"), which I elected to get a wired keyboard with, as I use the numeric keypad a lot.  I have an old iMac (2007) that has a similar keyboard.
    Today, my new iMac crashed.  I have no idea what happened, but I plan on blaming Oracle's VirtualBox for sucking.  I had to do a hard reset (hold power button down until system turns off, then turn back on).  Everything came back OK (thankfully), except the brand new keyboard.  The iMac wouldn't detect it, got the message "No keyboard found" on the main screen and it started looking for a Bluetooth keyboard (which I don't have - I have the Bluetooth Magic Mouse, just not the keyboard). 
    Fortunately, my old iMac is right across the room, so I grabbed the wired keyboard from there, and plugged it in to the same USB port that the new keyboard was plugged in to, and everything is fine.
    Here's the baffling part: I plugged the new keyboard into the old iMac and it works fine.  So, I swapped them back, no dice, keyboard AWOL again.
    I've tried other USB ports on the new iMac, the new keyboard doesn't register anywhere.
    The new keyboard works fine on the old iMac.
    The old keyboard works fine on the new iMac.
    I've tried rebooting the new iMac, still nothing.
    The USB port on the new iMac clearly works, as I can run the old keyboard from it, and even other hardware like a hub, iPhone sync cable, etc.
    What in the name of Jobs is going on?
    Fundamentally, I'm fine, the old keyboard is in find condition, everything works, blah blah blah, I'm just stumped.  Stumped, I tell you!

    Replying to myself with a bit more info.
    On the left, the new keyboard attached to the old iMac (thanks, Remote Desktop), on the right, the old keyboard attached to the new iMac.  Clearly minor version changes between the two, but . . . what the heck?
    I've now tried an SMC reset (http://support.apple.com/kb/HT3964) based on an old suggestion in another thread, and resetting the permissions (dunno why, it was part of the recommendation).  That hasn't worked.  The new keyboard doesn't even register in System Information when it's plugged in to the new iMac.
    Yes, yes, First World Problems and all that, I just want to make sure there isn't some other issue I'm missing here.

  • Attempting to create an interactive map with flash - getting errors with my actionscript

    I'm currently having an issue creating a set of buttons that are supposed to turn individual layers on and off.  The layers I have are: fishing spots, facilities, trails, map elements, an aerial photo, and parking lots.  It is giving error #s 1119 and 1120.  Could anyone explain possible reasons I'm getting these errors. 
    It might be worth mentioning that I used a tutorial made with Flash CS4, but I'm writing the code in CS5.  Here is the exact code I'm using:

  • Wired keyboard issues-caps lock won't turn off and other keys do not type

    I sat down today to use my May, 2010 iMac.  Fully up to date with Lion.
    I am using a WIRED keyboard. 
    The caps lock key is permanently on and the remaining keys when pressed do nothing.  They do not work.  You can press the keys down but they don't type any letters or symbols of any kind.
    I cannot log in because I can't type my password as the keys don't work.
    I can't do a PRAM reset because the  P and R keys and others don't work.
    I don't know what an SMC reset is but I can't do that either because the keys don't work.
    Why would a keyboard stop functioning?  Yesterday, it was just fine.  Now it doesn't work. 
    What causes the caps lock key to stay on?
    I have unplugged the keyboard etc, but nothing changed. 
    Doesn't anyone know how to correct this problem?  Do I just need to buy a new keyboard? 
    I called Apple but they were closed.

  • IMac late 2009 with 6GB RAM, slow with Yosemite

    Have you ever used that small pc computers with slow processors, called netbooks? This is what my super fast iMac late 2009 (6GB RAM) with Mavericks turned into, after upgrading it to Yosemite OS X.
    I mean, processor itself doesn't look to busy, but user experience is click and wait (when nothing happens, I almost want to click again but then action happens). Opening window animation is like slide show - it is not smooth as it was before, with Mavericks.
    Anybody with iMac late 2009 can confirm this or is it my setup only?
    I have the basic late 2009 model, except I upgraded it to 6GB RAM soon after I purchased it.
    This is how my About this Mac looks like:
    And this is how my hard disks look like:
    Nothing specially busy here, just slow Yosemite. When I open Safari, Mail, iPhoto and iTunes, it is not good to open any other app, because I might wait much more. I caught my self using iPad while opening fifth app on iMac (just to get an idea, how very slow it feels).

  • Speed issue macbook5,1 extremely slow under lion

    Often have to "force quit" Aperture, Omnigraffle, Safari, Skype never open at the same time.
    The speed is very slow.
    MacBook 5,1  OS-X Lion 10.7.3,  Ram 4Go,  HD WD-6400 ScorpioBlue

    Run the Apple hardware test from your Snow Leopard disk that came with the system. Insert the one that says 'AHT Version x.x' in small print on the label. Boot holding the D key down (or hold the alt/option key and choose the AHT when prompted). When prompted, choose the extended test. Does this identify any hardware issues?
    Bring up Disk Utliity, choose the internal hard drive, and on the first aid tab do a verify disk. Does this identify any issues? If so, go into Lion recovery mode (boot with command + R) and use Disk Utility to repair the hard drive.
    Assume you have plenty of disk space available for application and system usage? Minimum of 5GB, and more is better.

  • 2011 MBP with 8GB of RAM, generally slow under Lion, possibly thrashing

    I have a 17" 2011 MBP with 8GB of RAM and the fastest CPU available at the time.  It came with Snow Leopard, and it was really fast with basically everything I threw at it.
    Since the upgrade to Lion, it has a general tendency to get really unresponsive.  My workload hasn't fundamentally changed.  Rather than just hope it's bugs in Lion that will get fixed, I'd like to see if anyone can advise me on things I might investigate, either to fix things myself, or to be more intelligent about identifying bugs I can report.
    One thing I notice is that Time Machine backups will bring the system to its knees.  Everything will be going along just fine, and then TM will kick on, and all my apps will stop responding.  Once TM has finished, things will slowly come back to normal.  There's a lot of disk activity, which I have assumed was swapping.  Another thing that causes trouble is that mds (and a whole bunch of mdsworkers) will frequently kick on, and will slow down the system.
    CPU load is always quite low, but free memory is always very low.  (However, in some OS's Free Memory is misleading, because a lot of disk blocks are cached in RAM, so it's not really "used" either..)
    What I can't really distinguish for sure is if the system is slow because of swapping/thrashing (which is what I assume) or if it's slowed down for some other reason related to disk activity.
    Here are the apps I typically run:
    - NetBeans (which is a pig, taking up over 1GB or real memory)
    - Safari (which is also a pig, often taking up more than 1GB between the main Safari process and the Web Content process)
    - Sometimes Parallels (2GB for the VM, and probably another 1GB for other stuff, because it's also a pig)
    - kernel_task typically reports taking up over 1GB of real memory
    - WindowServer also reports using 280MB
    - various other small apps like Mail, NetNewsWire, Preview, Terminal, Adium, Smultron, Colloquy, none of which use much memory
    I got the 8GB, because I knew I was going to use a lot of memory for stuff, and it was great under Snow Leopard.  But with Lion, it just doesn't seem to be enough.  Even with all of those huge processes, I can't believe that their working sets are really as big as their virtual and physical memory footprints seem to be.  I mean it's not unusual for a process to have 2GB of virtual space but only a few 100MB of real memory, and some of that is shared object libraries, where the same physical memory is mapped into multiple processes.  (Have shared object libraries stopped being physically shared under Lion?)
    Are other people having similar trouble?  Any suggested remedies?  Any suggestions on how to investigate so I can see if there are any actual bugs?
    I would like to understand why my system went from zippy to slow after I upgraded to Lion.  Actually, quite a few things have broken.  Time Machine has become a pig, bluetooth doesn't work reliably anymore, airport doesn't connect reliably anymore, and lots of little annoying bugs.  But this is common for early point releases of new OS's, so I can't complain too much.  But for Lion to have really regressed in memory management is definitely not good.

    Safari, for what ever reason, has become a huge memory
    pig.  The longer you are using it the more memory it
    gobbles up.
    In Activity Monitor, check the Page outs and Swapped used.
    This will tell you how much memory swapping is going on.
    As for Time Machine, you may want to set your Parallels
    HD image not to get backed up by Time Machine.  May
    help since it is a huge collection of files.  But there have been
    issues reported with Time Machine and Lion.  I don't
    use it myself and opt for the cloning methodology and
    seperate data backup strategy.  Also, in Spotlight
    preferences under the Privacy Tab, I have added
    my Windows VM folders, for same reason.  Unless you really
    need to find something on the windows VM volumes when you
    don't have the Windows VM active, it just eats up alot
    of disk access time.
    For solving airport issues check this article:
    http://reviews.cnet.com/8301-13727_7-20117247-263/fixing-airport-problems-in-os- x/?tag=mncol;txt
    For Bluetooth devices, try removing them, and have them rediscovered if you
    can.
    Hopefully, this gives you a start on cleaning things up.

  • Flash movie slowing with each loop?

    My main flash movie is made up with scenes, on each scene I have used the UILoader component to load external swf content to the main movie, the first one works fine but gradually with each loop the movie slows down, i have a globe in one scene which is looking really juddery... Can anyone help?
    Thanks
    Darren

    First off, you should not use scenes - they have never really worked all that well, and just lead to problems. Aside from that, if you're adding listeners to your loaders you need to remove them - or use weak references, which you should always be doing anyway. Have you looked at task manager to see if successive loops are using more and more ram and/or more and more cpu cycles?

  • Wired keyboard issue after 10.9.4 update

    Hello all,
    I disconnected the Apple USB keyboard (A1243) from my MacBook Pro last night, and I started seeing an issue where my Mac would no longer power/recognize my keyboard once I reconnected it. I tried doing the steps to reset both SMC and PRAM, but still my keyboard would not work when connected. I decided to test the USB port so I connected my iPhone to it, and it connected and synched just fine. I also tested a USB drive on it and was able to copy files off it. I also took my Mac keyboard and connected it to a Windows 7 laptop, and it worked just fine. After looking at the console logs, I noticed this error showing up:
    7/4/14 8:24:40.000 PM kernel[0]: USBF:    18393.519    AppleUSBHubPort::FatalError - Port 2 of Hub at 0x14200000 reported error 0xe00002c0 while doing setting port power
    This shows each time I connect my Apple keyboard into the USB ports on my machine. I decided to try to connect the keyboard one last time just now and it finally worked. I was accidentally pressing the keys down as I connected it, and I started hearing beeping sounds from my speakers. A few seconds after that, the keyboard started typing and working correctly. I tried the same steps on the original USB port I had it on before (left side), but it's still not working at all. I suspect that this has to do with the new update I just installed as I did not have any issues before.
    Many thanks,
    Adrian C.

    To confirm what John Galt is reporting, I just tested printing this web page from OS X 10.9.4 to an old HP LaserJet here.  Worked correctly.
    In addition to what John Galt is asking, which model(s) of HP printers are involved here? 
    If you're getting error dialogs or messages in the console log (available via Console.app), please post those.
    If you're working with an IT organization and particularly with managed network switches, have you checked with IT about issues there?
    If there are any antivirus or antimalware tools in use here, remove that miasma from at least one test system, and test printing again.

  • Bluetooth does not work correctly with Flash when dealing with audio

    I have a stereo that uses bluetooth. I am on a Mac.
    Everything works with bluetooth (iTunes, Quicktime) except flash.
    When I play a flash video, or listen to songs using a flash player,
    no sound is playing through the remote (bluetooth) speakers.

    Ditto - I get the same issue with a bluetooth headset. If I
    download the flash video to my mac and play it using VLC it works
    fine, however the flash player chokes on it. Any ideas?

  • Watching movies with Apple TV slow with Time Capsule

    I recently got rid of my Linksys router and replaced it with a Time Capsule, it acts as my backup storage as well as my router.
    Ever since then, my apple TV is extremely slow when downloading movies. It used to take about 30 seconds to be able to watch the movie and now it's 1-4 hours.
    My network speeds are fine, I can do speed tests and get 5-10Mbit down, so I'm not entirely sure what is going on.

    Hello optize. Welcome to the Apple Discussions!
    I assume that you are using the new Time Capsule (TC) to stream movies to your Apple TV (ATV) ... correct?
    If so, to improve streaming performance, you may need to try some of the following to find what will work best for your network configuration.
    o If both the TC & ATV are wirelessly connected to each other, switch the radio mode to "802.11n only (5 GHz)."
    o If you must operate your wireless network in the 2.4 GHz radio band to support non-"n" clients, try a different radio channel.
    o Connect the TC & ATV by Ethernet.
    o Temporarily disable Time Machine backups from running when streaming movies.
    As you are probably already aware, the iTunes Store offers both standard definition (SD) and high definition (HD) video for rental and purchase. MPEG4-compressed 1,080p requires about 10 Mbps of throughput to stream without artifacts. As such, Apple’s SD and HD video would require between 2 and 5 Mbps for decent streaming over a network. A 802.11g network should top 20 Mbps in throughput, but could be lower speeds due to Wi-Fi interference. In contrast, a 802.11n network, with only n devices connected, can hit 90+ Mbps.
