Photos does not recognize one of my devices, please help.

None of my cameras, my iPhone, iPad and even an SD card into the slot are recognized as devices by Photos, iPhotos or Image Capture. Have you tried different USB ports, different cables, all software, firmware, etc. is up to date.  Image capture also does not recognize my scanner.  They all used to work fine, now, they do not.  I have a Mac mini end of 2014 with El Capitan version 10.11.4.  Believe, that was the last time everything worked fine before El Capitan.

Devices are not at all in applications or only applications simply cannot open, when you connect a device?

If the problem is, that the applications do not open, but the devices display, try this command in Terminal:

  • Photos of quit smoking and unplug any camera.
  • Open a Terminal and paste this command and press return:

default - currentHost write com.apple.ImageCapture disableHotPlug - bool NO

  • Restart the Mac. It is not necessary, but it worked for me after the reboot.

If the devices don't show at all, you may have installed system extensions that interfere.  Give it a try.  Restart your Mac in Mode without failure. Then, connect a camera or card.  Image Capture sees the devices safe?

    UPDATE (04/03/2010):

    -J' repeated the steps above 1 to 3, with open Device Manager.  In step 3, in the Device Manager window, the icon for the question USB mass storage device becomes the exclamation point in yellow triangle icon.  Check its properties on the tab "General", in the "Device status" box, it says: "Windows cannot use this hardware device because it has been established for"safe removal", but it has not been removed from the computer. (Code 47)  IX this problem, disconnect the device from your computer and then reconnect it.  Click on 'Search for solutions' to send data about this device to Microsoft and to see if there is a solution available. »

  • Photos does not recognize the Sony Handycam

    Until yesterday, when I connected my VCR (Sony Exmor R) on my Mac, photo open and offer to import new clips. Now, he does not even recognize the device contains clips. (She sees it as an external hard drive but I can't get my picture).

    Hello noemiebill,

    Thank you for using communities of Apple Support.

    I see that your Sony camera is not recognized in the Photos for Mac.  I would like that you perform the steps below for assistance.  Even if the title of the article is for iPhoto, the same steps apply to Photos.

    1. Make sure that the camera is compatible with iPhoto.
    2. See the documentation for your camera to see if there are several modes that the camera can use to communicate with the computer via USB. Some devices have a mass storage mode, and some devices include an option to place the camera in mode photo-transfert-Protocol (PTP). Try each mode to see if the camera can be recognized by iPhoto.
    3. Make sure that iPhoto and Mac OS X versions are updated. Mac OS X updates include additional camera support.
    4. Turn on the camera and connect it to the computer. Check system information (in the Utilities folder) if the camera is shown as connected by USB.
    5. Open Capture of Image (in the Applications folder) and see if the camera is recognized in this application. If your camera is still not recognized by iPhoto, check if the camera has a removable storage card, such as a Compact Flash (CF) or Secure Digital (SD) card. If so, you may be able to mount this card and read files photo from the Finder, if you have a USB or FireWire card reader connected to your computer.
