Jumpy, erratic trackpad on MBA (Is there a firmware update?)

There have been complaints about jumpy/erratic/random cursor behavior with Macbook Air's trackpad. I have the same problem, and it's driving me nuts.
However, I noticed that, from users who were complaining about similar behavior on their MBP mentioned an April 12 keyboard firmware update that seemed to have solved their issue.
Does anyone know if there is something similar for the MBA that can solve it.

Hi guys, I thought I was going crazy here after owning my MacBook Air for a couple of months now.
This happens to me as well. In fact, it happened a few minutes ago and I had no other choice but to hit the power button and select Shut Down. After a restart, it was fine. I have seen this problem come up a few times on this machine.
Sometimes the trackpad would not respond at all, the cursor doesn't move. At other times, it has a mind of its own and seems to 'catch up' to my actions and moves around the screen really fast, starts right clicking, clicking on things, being erratic.
I have also noticed that I'm unable to drag-lock (tap and keep a selection) and sometimes lose the ability to right click with two fingers.
I may have to get this looked at but I don't want to put this baby in for servicing since it has had a clean record.

    To give an update on this issue, here is the latest information I have:

  • Is there a firmware update for burning at 16x with Matshita DVD-R UJ 845E?

    Is there a firmware update for burning at 16x with Matshita DVD-R UJ 845E? I'm trying to burn a DVD using iDVD on my iBook. The blank DVD's are Memorex 16x (I've used Memorex 8x successfully in the past), the DVD drive is specified above. The finder tells me that the drive has reported an error "sense key=medium error/ sense code=0x73, 0x03" I couldn't find firmware updates in either Panasonic Matshita or Apple websites. Am I forever confined to 8x DVD-R's with this laptop?

    First, welcome to the discussions.
    Sorry, No Firmware update to allow you to burn at 16X.
    The drive you have is only capable of burning at 8X.
    You will also find that for the most part when you recieve errors that it is more often than not attributed to MEDIA.
    There are so many problems with the cheaper media they are to numerous to cover.
    DVD is not at all like CD burning, in that the technology as well as the Optical Drives used, seem to be touchy, and require the use of good Media. This will allow you trouble free burning without errors.
    http://www.digitalfaq.com/media/dvdmedia.htm
    You will also find that the reason that DVD-R Media works the best, is because it is the most wirely used and recognised in both Computers and Players.
    If I may suggest. There are several 16X DVD's on the market.
    Take your time and look at the back of the Jewel Cases and read. You will see that the better Media will tell you that it will burn at 1X through and including 16X, if your drive is capable of handleing these speeds. I prefer Maxell 16X DVD-R Media in the individual Jewel Cases. This Media burns at the slower speeds on the older Superdrives that will only burn at 1X or 2X.
    Like many others I have learned my lessons the hard way.

  • Is there a firmware update for the Apple RAID Card [early 2009 Xserve] that will take it beyond the E-1.3.2.0 version and allow it to see 4TB drives?

    Is there a firmware update for the Apple RAID Card [early 2009 Xserve] that will take it beyond the E-1.3.2.0 version and allow it to see 4TB drives?

    I have a few of these RAID cards in a couple servers, and then I have an earlier version of the RAID card in a few different servers.
    The earlier servers are running non-apple 1.5 TB drives. It will be interesting to learn if this firmware update will indeed allow me to boost the capacity by installing non-apple drives, as the firmware previously has not.
    Ohh I'm excited to update and try! This will greatly help out if it does!

  • Is there a firmware update for ipf5100 and OS 10.10?

    I have just restarted my ipf5100 after a long downtime. Current firmware version is 1.43. I see canon has a firmware update for Mac OS10.8 and 10.9. Will that work for 10.10, or is there another upate for 10.10?

    don't think there is an update for the firmware as of now.

  • I don't have an option for Power Nap in my Energy Saver preferences...is there a firmware update forthcoming?

    So I have a Retina MacBook Pro.  After installing Mountain Lion, I noticed that my email, calendars, notes, etc, are not updating when my Mac is asleep.  There are currently no updates for my Mac available right now.  I've seen people say that there is an option under the Energy Saver preferences that turns it on and off.  Tried reseting PRAM. 
    Anyone else seeing this?

    Yes, this requires a firmware update. Just sit tight and look for an update to pop up shortly.

  • HT2497 I updated my macbook pro to mountain lion, and now I have issues connecting to my airport extreme it states that it can not find a IP address.   Is there a firmware update that could resolve this

    I am looking for the updated wireless utility or updated firmware for my airport extreme. 

    The maximum OSX for a 2007 17" MBP is Lion, 10.7.5.  stedman1 is correct.

  • My TCs say there is Firmware update to 7.6.4 but in the middle of updating stuck...

    I have 2 TCs and one Airport Express, all running Firmware 7.6.1.
    Now Airport Utility says I should update them to Firmware 7.6.4.
    The progress bar shows updating going on until about one third. Then it stops and a modal dialog says "a problem occured" or similar.
    It makes no difference from which computer I do the update, nor which Airport device I select to be updated, always that unspecified error after one third...
    My suspect is that the image of 7.6.4 is not completely loaded on my computers. But where is it stored and by what utility? How can I reinitialize the complete process of updating?

    Try to do it with ethernet.. do not use wireless.. turn wireless off.
    And make sure the TC is either in router or bridge mode to the main modem/router in the network.
    If possible do not use Mavericks.. it has more bugs than your normal insect zoo.
    The files are stored in the computer before the update even begins.
    ~/Library/Application Support/Apple/AirPort/Firmware
    Tell me which model TC you have .. A1xxx from the rubber mat and I can tell you the size of the firmware file.
    Or you can see it yourself.. it is in version.xml but most seem to be about 6.6MB eg.
    7.6.4.basebinary newest productID 117 sizeInBytes 6600996 sourceVersion 76400.10 version 7.6.4 location http://apsu.apple.com/data/117/041-9694.20130207.Dr0pg
    The actual file will be slightly different of course depending on the model.
    The information is here..
    http://support.apple.com/kb/HT1218
    You can apparently do it from the iOS version of the airport utility.. which might work better than Mavericks.. well anything would wouldn't it!!

  • Are there any firmaware updates for time capsule?

    Are there any firmware updates for Time Capsule/Time machine?
    I just had a new hybrid (SSD and spinning disk) drive (750 GB) installed on my MacBook Pro and used Boot Kamp to partition it and run Windows xp. Now, my previously working Time Machine won't function. It says the "sparsebundle" is open (or in use)  preventing the back-up from working properly. When I try and remove and re-install Time Capsule as the disk to back-up to, it still doesn't work. My plan "B" is get a second Time Capsule and dedicate it to the MacBook. But, I fear I'll face the same problem.
    When I open to reconfigure Time Machine, the Time Capsule disk is identified as the back-up, but it's also seen in the "available disks to use for back-up" along with with Boot Kamp disk which is part of the new SSD hybrid hard drive just installed. (Remember it's the partitioned part running Windows xp.)
    I've unplugged/plugged-in the ethernet internet connection and the power cord many times to no avail. The message still says the sparsebundle is in the way.
    Do you think deleting Boot Kamp disk from the list of available hard drives might solve the problem?
    Bill in Tulsa

    TM can only use AFP and only on disks formatted HFS+ (ie Mac Extended Journaled) so it should not bring up a boot camp partition as a possible destination at all .. but I have not done that seutp.
    It says the "sparsebundle" is open (or in use)
    That error is well known. It should simply required the TC to be restarted..
    That sometimes gets things working where the simple restart won't.
    I would recommend using short names, with no spaces and pure alphanumeric. 
    That is C9
    http://pondini.org/TM/Troubleshooting.html
    If you have a more complicated setup.. I would recommend firstly doing a TM reset in the computer.
    See A4 in the same reference.
    Do a verify then of the sparsebundle on the TC.. A5 but you might need to inherit the old backup if you want to continue an old backup.. A new hard disk will make the TM consider the old backup no longer belongs to the computer.. there is a UUID connection to the actual hard disk used in the backup.
    Again read the info in pondini. B5 and B6.
    The sparsebundle in use is C12 but there are a number of sparsebundle issues in section C.. C17 is another common issue.
    Some of what you have done is not adequate.. eg disconnecting ethernet is not enough.. you need to reboot the TC.

  • Erratic trackpad due to humidity?

    I have an erratic trackpad on my min-09 MB Pro, which began this evening. The pad is unresponsive to hand motion but also generates spontaneous cursor motion and clicks. After some googling, I saw that the pad can be sensitive to humidty and failing to cure the problem with restting the PRAM I took it down to the basement (55% humidty down here). Almost instantly the behavior disappears and normal operation is restored. I have tried the calibration by palm proximity technique and cleaned both the pad and my hands, to no avail. Is there a fix for this in software (ie calibration file)? If I swap a new keyboard/pad in will that fix it?

    I should note, the erratic behvior returns if I go back up to the kitchen and disappears when I return to the basement. The humidity level in the kitchen is high but not out of the ordinary for New Jersey. I am not shutting down or sleeping the machine while moving up or downstairs.

    If you don't already have a current backup, back up all data, then reinstall the OS.* You don't need to erase the startup volume, and you won't need the backup unless something goes wrong. If the system was upgraded from an older version of OS X, you may need the Apple ID and password you used.
    If you use FileVault 2, then before running the Installer you must launch Disk Utility and select the icon of the FileVault boot volume ("Macintosh HD," unless you gave it a different name.) It will be nested below another icon with the same name. Click the Unlock button in the toolbar and enter your login password when prompted. Then quit Disk Utility to be returned to the main screen.
    There are ways to back up a computer that isn't fully functional. Ask if you need guidance.
    If you installed the Java runtime distributed by Apple and still need it, you'll have to reinstall it. The same goes for Xcode.
    *The linked support article refers to OS X 10.9 ("Mavericks"), but the procedure is the same for OS X 10.7 ("Lion") and later.

  • Erratic trackpad issues

    Recently, my trackpad has been acting up.
    Symptoms: (just SOME, not all)
    -cursor/arrow will move on its own
    -random areas will become highlighted
    -gestures are wonky (ex: swiping from left to right with one finger will change entire desktops)
    -screens will zoom in
    -left mouse click acts as if the right mouse button was clicked
    It's almost as if someone has taken control of my trackpad.
    Note: I have Lion 10.7.1
    Remedies already tried:
    -PRAM reset
    -SMC reset
    -shut down computer and let rest for a few hours
    -software update
    -turning off all trackpad and gestures
    I've read Apple's official explanation for an erratic trackpad (which was useless to me) and other users' experiences but none seem to match what's going on with mine.  I know I can take it to a store and have some "Geniuses" look at it, but I was hoping to exhaust all possible at home solutions first.
    Has anyone had similar problems, and what did you do???
    I really appreciate any feedback.

    Ralph,
    I tried the SMC Reset - and it helps to an extent. It works fine, albeit a little sluggish, for about 10-15 minutes before it becomes sluggish and erratic again.
    The magsafe led colour is either orange/yellow or green (when fully charged). The charge button on the side shows that green lights fill up except for the last one which flashes.
    I'm now trying a software update but I don't know if that will work.

  • Macbook erratic trackpad and stuck on right click! NEED HELP!

    Hi,
    Got a Macbook Unibody, 10.6.8, 2.4GHz, 8GB RAM.
    Basicly it was working fine. I installed a driver for a Tascam audio interface, still working fine for about 2 hours. Took it round to my girlfriends and after a few more hours the pointer started moving around the screen on it's own, clicking only operates the right click function and it will right click on it's own sometimes.
    I've removed the driver and software that came with the Tascam Driver the best I can (Not sure how to do it fully on a Mac, Windows is much better at these things!), I've clean the pad itself and tried 'resetting' it by placing my palm on it for a few seconds. All these things haven't worked.
    USB mouse seems to work ok but even the erratic trackpad will take over sometimes.
    The interface was plugged in via USB and I'm wondering if this could have effected it?
    Any help is much appriciated, it seems like everytime I touch her computer something goes wrong with it!!!
    Oh and no Apple warranty so going to apple ain't an option.
    Many thanks,
    Karl.

    If you have a model with a removable battery, pull the battery and try running without it. I had a problem with my battery swelling and it created all weird trackpad issues. I replaced the battery and it cleared them all up.

  • MBA Firmware Update - iTunes/Filevault

    I just updated my MBA with the new firmware.
    After, I opened iTunes, and it tells me:
    *The folder "iTunes" cannot be found or created, and is required. The default location for this folder is inside the "Music" folder"*
    I have: /Users/me/Music/iTunes... so not sure what it's complaining about.
    Finally found a post from someone saying they needed to turn off Filevault for iTunes to start properly, and when I tried to turn Filevault off, I get this:
    *Turning off FileVault requires an additional 8.0 GB of free disk space on teh volume 'me'. Try emptying the Trash or deleting files you don't need*
    What is there an image mounted with my name on it anyhow?
    Any suggestions!? I'm at a loss of what to do !

    Same problem for me running the same Boot ROM version. Attempted to install 4 times plus manual download/install. All failed. This SMC version isn't listed against 2.9, but probably is meant for this version as well. The issues mentioned i.e. not waking from sleep and over clocking fan are problems I encounter every so often.

  • Trackpad Firmware Update 1.0 Freezes / Hangs

    I had a brand new MacBook out of the box a day ago. The only thing attached to it was the power cord. After a fresh setup for a new user a number of Apple software updates were found and I agreed to install them. Upon the first reboot the Trackpad Firmware Update application started up automatically. A gray box appeared with a warning not to interrupt or shut the power off to the Mac. I clicked "update" and the status bar started moving (no other applications had been opened). It got to about 95% done and hung. A one inch thick line of dark gray appeared to cover the top edge of the screen (it was translucent so I could still see through it).
    I left the computer alone for 10 minutes because I was warned not to interrupt or shut the power off during the firmware update. With great reluctance I eventually pushed and held down the power button (there was no possible way to "Force Quit Applications" and the computer appeared completely hung).
    After powering back up the machine the Trackpad Firmware Update application says the firmware is up-to-date and the trackpad appears to work. So it appears all is good. My questions are:
    1) Is anyone else having this issue?
    2) It is quite concerning to see a firmware update hang. Is it possible, or even advisable, to redo the update? The updater application won't allow it because the firmware is supposedly "up-to-date" but clearly there was an issue with it completing properly.
    3) Can anyone explain what happened?
    I have noticed people having other problems with the update but only a few talk about it freezing up or hanging up during the update itself.

    Seems like some others have had this issue as well but certainly not everyone. I found the following:

    There is an article on "recovering from an interrupted trackpad firmware update" here http://support.apple.com/kb/HT3312 but it seems to say you should be able to try updating again. When I relaunch the updater it says the firmware is up to date even though it never appeared to complete before I had to force a shut down. Hopefully a newer version is released sometime that doesn't freeze the system when installing.
