La webcam del mio mac book pro display retina quando cerco di avviare un applicazione che usufruisce di essa mi dice che non è collegata, che cosa devo fare?

quando cerco di avviare isight con photo book o facetime mi dice nessuna fotocamera collegata

Quale versione di OS X sono in esecuzione? Se Lion o leone di montagna, tenere premuto il tasto opzione e selezionare Informazioni di sistema dal menu Apple. Controllare sotto Hardware> USB per vedere se la vostra videocamera iSight o FaceTime sta mostrando. In caso contrario, o se è semplicemente non funziona, è necessario prendere la macchina nel vostro Apple Store o un Apple Authorized Service Provider.
Buona fortuna,
Clinton

  • HT1338 my MAc Book PRO 13" Retina display will not update.  It crashes every time I try to do an update.  I have sent in the information on each update but so far nothing back from Apple.

    my MAc Book PRO 13" Retina display will not update.  It crashes every time I try to do an update.  I have sent in the information on each update but so far nothing back from Apple.  Also it does not matter what I am trying to update, the operating system, and application, each caused the same crash.   This mac book is less than a month old.

    That is the highest you will be able to go with 3g. You need 3gs or 4 to go any higher (multi processors and more memory needed).  Version 4.2.1 marks the end of your updates for that device.

  • Need wireless monochrome laser printer for home office to use with new mac book pro with retina display. I also have to have networking capability. Suggestions for economic printers?

    HI, I need to buy an economic monochrome laser that will work wirelessly with new Mac Book Pro with Retina Display inmy home office. Any suggestions?

  • I can't add printers to my new mac book pro with retina display

    I am trying to set up my HP wireless printer to my new mac book pro with retina display.   I can't get it to work!  I have down loaded the latest driver for my printer, and when I go into the printer area and try and add the printer, nothing shows up and it won't let me even add it.   I can't seem to connect my mac directly to my printer either as I must need a different cord as there does not seem to be a port for the "phone like jack" that I could fall back on with my old Mac.    My printer prints great so I hate to just buy a new printer, but I can't get this to work.   My wireless router is located in the basement, far away from where I keep my printer so it also makes it hard to rest everything.  I even bought the blue tooth adaptor for the HP printer thinking that would solve it all, and nope!  Any help would be greatly appreciated!

    I have made some progress.... I can print wirelessly from my printer now, but I can't set the printer itself to be wireless.  I had to move my printer downstairs to where my router is...which is not that convient.   I printed up the page you asked about....and as expected, it says it is off line and there is no IP address.    So now I need to figure out how to make my printer itself wireless.  I did download the HP driver I needed...but I can't access it to do anything else.  It seems l like I am missing a step... or I need to hook up my computer itself to the printer to help get the printer to be wirelss, but I can't hook it up because there is no port for me to do that (no port that looks like a phone jack).  I am guessing I would need a different type of cord, but I am not sure what kind of cord that would be! Ugh!

  • My hard drive won't mount on 2012 mac book pro with retina display

    The flash drive in my Sept 2012 mac book pro with retina display is not mounted, won't mount,  and can't be repaired in disk repair.  I need files created right before it failed last night that were not backed up.  Can they be salvaged before a new warrantied drive is put in at my request?   Also is this failure a common problem?

    Hi I have just bought a new Mac Book Pro 15" Retina display with 256 SSD and 8G RAM. I had my info transferred form my Previous Mac Book Pro late 2011 to this machine. When trying to download Mavericks it says it cannot be loaded onto this machine? Strange as I have just downloaded Pages, Numbers and Keynote...free? Thanks and Regards
    Brian

    Welcome to Apple Support Communities
    You already have got OS X Mavericks installed (the Keynote, Pages and Numbers versions available in the Mac App Store are only compatible with OS X Mavericks).
    You have got a Late 2013 MacBook Pro, which uses a special OS X Mavericks version that is not available in the Mac App Store. This is the reason why the Mac App Store is not compatible with OS X Mavericks even if you are using it. This will be fixed in OS X 10.9.1, when your Mac uses the same Mavericks version as all other Macs.
    Until then, you can reinstall OS X through OS X Recovery > http://support.apple.com/kb/HT4718

    If or when upgraded to the max, the Retina is a good value.
    But talk to other users on the notebook forum.

  • After Security updation of Windows 7 in Boot Camp (Mac Book Pro with Retina Display) on 13-Nov-2013, Windows 7 Desktop Gadgets are not working properly.

    After Security updation of Windows 7 in Boot Camp (Mac Book Pro with Retina Display) on 13-Nov-2013, Windows 7 Desktop Gadgets are not working properly.
    This is boot camp problem, because in other normal notebooks (e.g. SONY VAIO, Lenovo with Windows 7) the gadgets are working normally.
    I am attaching the screen shot of Desktop Gadgets and Security updates of Windows 7.
    Kindly solve this issue ASAP.

    You are not addressing Apple, but a community of unpaid volunteers. So ASAP won't cut it. Also, you should refrain from posting personal information (like your email address) in the body of your comments, as this is part of the community usage guidelines.
    Have you reinstalled the latest Boot Camp Windows 7 drivers, just in case Microsoft overwrote some of them during the Windows 7 security update?
    If you want to communicate issues with Apple about Boot Camp and OS X, click on the link. Just don't hold your breath on receiving a response.

    would like to convert my LPs to digital on my new mac book pro with retinal display
    . How can i do this?

    The new Mac's do not have analog audio in so you will have to go with a USB audio in device or else if you do not yet own a turntable (or are looking to upgrade) you could get a turntable that has USB out.
    The Griffin Technology iMic USB Audio Device is a low cost consumer grade solution if you already have a turntable.
    For recording I use Audacity: Free Audio Editor and Recorder which does a good job and has the ability to run the audio signal through various filters.

  • My mac mac book pro w retina display will not go to sleep when I close the lid or put it to sleep.

    My mac mac book pro w retina display will not stay asleep when I close the lid or put it to sleep.
    I put the computer in my bag and when I open it again the machine is so hot I can almost not touch it.
    I am affraid that the hardware is allready fried.
    Also when I press a key to restart after it has been idle for a few minutes it often takes up to a minute to wake back up.
    This machine is bran new..
    What should I do?

    Try a SMC reset:

    If no success, then use your warranty and bring it in to the nearest Apple repair facility for rectifying this problem.

    Hello psadana,
    Thank you for the details of the issue you are experiencing with Wi-Fi on your MacBook Pro.  I would be concerned about this too.
