  • Wifi on my mac OS X 10.9 running marvericks its saying no hardware installed, what could be the solution?

    https://discussions.apple.com/discussion/create.jspa?containerType=14&redirectUR L=%2Findex.jspa&question=true&containerID=2998&subject=wifi on my mac its saying no hardware installed, what could be the solution

    There are a number of possible reasons for that message, including defective hardware that only Apple will be able to fix. The steps you can perform yourself are as follows:
    1.
    Perform an SMC reset. Read all the steps.
    Before Resetting the SMC
    Try each of the following steps in this order before you reset the SMC. Test the issue after completing each troubleshooting step to determine if the issue still occurs.
    Press Command + Option + Escape to force quit any application that is not responding.
    Put your Mac to sleep by choosing the Apple () menu from the upper-left menu bar and then choosing Sleep. Wake the computer after it has gone to sleep.
    Restart your Mac by choosing the Apple () menu from the upper-left menu bar and then choosing Restart.
    Shut down your Mac by choosing the Apple () menu from the upper-left menu bar and then choosing Shut Down.
    Resetting the SMC on portables with a battery you should not remove on your own
    Shut down the computer.
    Plug in the MagSafe power adapter to a power source, connecting it to the Mac if it's not already connected.
    On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time. The power adapter indicator light may cycle off / on once.
    Release all the keys and the power button at the same time.
    Press the power button to turn on the computer.
    Resetting the SMC for Mac Pro, Intel-based iMac, Intel-based Mac mini, or Intel-based Xserve
    Shut down the computer.
    Unplug the computer's power cord.
    Wait fifteen seconds.
    Attach the computer's power cord.
    Wait five seconds, then press the power button to turn on the computer.
    2.
    NVRAM reset:
    Shut down your Mac.
    Locate the following keys on the keyboard: Command (⌘), Option, P, and R. You will need to hold these keys down simultaneously in step 4.
    Turn on the computer.
    Press and hold the Command-Option-P-R keys before the gray screen appears.
    Hold the keys down until the computer restarts and you hear the startup sound for the second time.
    Release the keys.
    After resetting NVRAM or PRAM, you may need to reconfigure your settings for speaker volume, screen resolution, startup disk selection, and time zone information. If issues persist, your Mac's logic board battery (not a portable Mac's rechargeable battery) may need to be replaced. The logic board battery helps retain NVRAM/PRAM settings when your computer is shut down. You can take your Mac to a Mac Genius or Apple Authorized Service Provider to replace the battery on the logic board.

  • Brand new Imac and wireless is saying no hardware installed? really confused as it was working fine yesterday, brand new Imac and wireless is saying no hardware installed? really confused as it was working fine yesterday

    Hi Guys, I juts bought a new Imac and jad it connected to my wireless router yesterday but now when i click on the wireless button on the top screen, it comes up saing wireless hardware not installed, have any of you had this problem? Thanks Tracey

    You can quickly see if there is a problem in reporting the AirPort card by going to the apple in the upper left corner, About This Mac, More Info, System report and look at the information on Hardware and the AirPort report...make sure it is not indicating a fault.
    If all looks ok, try removing the network information and reentering it and see if the AirPort responds.

  • I owned a vintage MacBook late 2008.the problem is my network has jammed and showed no hardware install.what should I do?

    network icon showed no hardware install. Have checked the local dealer but they said the production of the hardware(air port card) has been discontinue and cannot be ordered from Apple. What should I do?macbook late 2008

    Put the Serial Number in here...

  • My WiFi is down and says ´´No Hardware Installed´´ and I´m not sure how to fix it. I´ve tried shutting it down and pressing P, R, Command, Option, but it only works sometimes, and as a temporary fix. What do I do?

    My WiFi is down and the icon states ´´No Hardware Installed´´. Sometimes the WiFi will come back, but it will shut me out after an hour or two. I´ve tried shutting it down and pressing P, R, Option, Command while turning it on, but it only sometimes works and is a temporary fix. I´m studying abroad and there aren´t apple stores near me. I went in to one before I left, and thought the tech employee had fixed it, but I started to have the same problem here. How can I fix this?

    This worked and solved the problem.

  • HT1692 when i connect my iphone to itunes it say its corrupted? what can i do i want to update my contacts and save them

    itunes could not back up the iphone becasue the backup was corrupt or not compatiable with the iphone...
    what do i do please

    I have a free app called MCBackup that creates a file that you can email yourself and it consists of a complete list of the contacts.  Good way to back them up and keep a copy from time to time. There is anothe app called TTvCard that does the same thing.  You might be able to open the email on the Samsung and have the contacts appear on the Samsung phone
    This might help with the google thing you mentioned http://support.google.com/a/users/bin/answer.py?hl=en&answer=138740
    If you google transfer iphone contacts to Samsung (then model number) you might find something useful

  • Okay Im thinking I made a mistake, I purchased and ipad 2 and now don't know what to do with it. I turned it on and it won't do anything but show the plug and itune symbol?  Can someone tell me what to do?

    I don't know what to do with my ipad2?

    I'm guessing you did not buy the iPad from Apple. If you did not buy it from Apple, it may very well have an older software version. Only iOS 5 or later is PC independent. If you have an earlier version, a computer with iTunes loaded is required.

    Have you attempted to reset the SMC? That would be the first step. Hold the left control, option, shift key and the power button for about 5 seconds and release. Then try to reboot. Might as well reset the PRAM as well. Hold command, option, P, R on start up until the machine restarts. If that doesnt' have any affect we'll have to dig deeper into a potential hardware failure.
    If this method doesn't work, check the webcam that will tell the problem is on the iSight & WiFi cable. If your webcam is ok, then it'll be the WiFi card problem. Hope it can help ;-)

  • I keep on getting this error when i try to copy files to my 2T Time Capsule, Please help im running out of space on my MacBook Pro.... The operation can't be completed because an unexpected error occurred (error code -50)

    I would get an external drive today and copy all your stuff off the TC.. forget trying to load more onto it. There is a good chance after 3years (A 2TB should be only about 2years tops), the disk or the TC itself is on the way out. Do it immediately. If TM is also failing to backup you need to recognise symtoms of impending doom.
    Unfortunately the error messages are archane and it is hard to discover their meaning.
    You also cannot verify a network drive.. you can verify the TM sparsebundle though so do that.
    A5. http://pondini.org/TM/Troubleshooting.html
    Reboot the whole network from off.. certainly if you run later OS it can simply lose the drive..
    If you still fail to be able to copy to the TC.. then get that external and copy off it. Tell us if you can do that.

  • HT1338 What's going on with iCloud (MobileMe)?  I'm able to sign in here, but I can't access mail on my Macbook Pro, iPhone, or work computer.  I always get an authorization error (user-id or passwork wrong).  This has been going on for almost a week now.

    The single download means that you won't be able to redownload it from the store without paying, either on a computer's iTunes or an iOS device - it doesn't stop you from copying the audiobook to your other computers or syncing it to your iOS devices, you just can't redownload it. (I believe that they are all supplied to Apple by audible.com, so I assume that it's them requiring the one-time download.)
    You can download audiobooks on your computer's iTunes and sync them to iOS devices, you do not have to buy them directly on the device (if you do then you can copy them back to your computer's iTunes library by connecting the device and using the File > Devices > Transfer Purchases menu option on your computer's iTunes).
    What you are doing to sync them should work i.e.
    - connecting the iPad to your Mac
    - selecting the iPad on your Mac's iTunes
    - selecting its Books tab and selecting the audiobooks that you want to sync to the iPad and syncing/applying that selection.
    You should then get an audiobooks option in the Music app on your iPad. If they aren't appearing there  then do they show in Settings > General > Usage > Music on the device - if you have audiobooks on the iPad then they should be listed there under an 'audiobooks' heading.
    By 'restart the iPad' do you mean a soft-reset : press and hold both the sleep and home buttons for about 10 to 15 seconds (ignore the red slider), after which the Apple logo should appear - you won't lose any content, it's the iPad equivalent of a reboot.
    You could also try closing its Music app via the iPad's taskbar : Force an app to close in iOS.
    And do a soft-reset and retry syncing.
    I assume that music and other items sync ok ?

    Hi Francis,
    Could you please let me know how have you been trying to install Acrobat?
    Please ensure that you are signed in as admin and antivirus software is disabled at the time when you install.

  • Working with final cut x (10.0.9) on macbook pro want to add compressor cannot download 4- where can I download 3

    working with final cut x (10.0.9) on macbook pro want to add compressor cannot download 4… where can I download 3?

    It has been available at some online retailers (Amazon) and EBay – but only as part of the discontinued Final Cut Studio suite. It would be cost--prohibitive to buy and there are other more cost-effective solutions. Depending on what you need to do, MPEG Streamclip might be a (free) solution. There are others – Episode, for example, which is not cheap at $500– but less than haf the cost of buying an used copy of FCS.
    Another approach (and the one I would follow in your situation) would be to install Mavericks on an external, bootable drive. Run a copy of FCP 10.1 and Compressor 4.1 from that drive.
    Good luck.
