Cannot display iOS device in El Capitan

The option to display the screen of the iPhone with video recording does not work in El Capitan, as it did in previous versions of the operating system

Hi, Dennis.

Thanks for the question and I hope that we can get this to work for you pretty quickly.  From your post, it seems that your iPhone is not listed when you attempt to select as the source with the option of video recording in Quicktime format.  If the iPhone is recognized in iTunes, tried several cables sync or USB ports, then I would suggest resetting the alert to "trust this computer" as it may cause a device does not show.  You can reset this setting two ways and I will include them in the article cited below.  If you choose the option reset network settings, this will remove the preferences of network such as locations remembers Wi - Fi.

If you use the iOS 8 or later: to untrust all computers, tap Settings > General > reset > reset location & privacy. This will also reset your location and privacy settings. You can also untrust all computers by clicking on settings > General > reset > reset network settings. This will reset your network settings also.

"Trust This Computer" alert on iPhone, iPad, or iPod touch

Once this is done, restart the computer and test using the screen of the iPhone with video recording.

Please let me know the results of these steps and thank you for visit Apple Support communities.

See you soon

    Hello

    Since when does the problem appear? This is the first time?

    I don't know, but if you didn t already reinstalled the drivers display, I would say it since sometimes the VGA driver dislikes the desires of the users.
    Please, go to the driver Toshiba download site (still ;)) and download the display driver.) Install and set only the screen inside.

    If it doesn´t work back and give feedback so that we can discuss more about your problem.

  • Cannot add a device Cisco IOS - development issue?

    I try to add a router IOS (as a platform) my Hyperic (3.2.1) resources and I kept getting this error (see the following stack trace).

    =============================================================

    So, I downloaded the src and it built with the following parameters of the construction.
    Windows Server 2003 SP2 (Standard edition)
    Java 1.5 update 15, Ant 1.7.0 JBoss 4.0.3SP1, PostgreSQL

    However, I still get the same error. After adding a few log statements, I realized that in NewPlatformAction.java ("run" method), the value of the agent is zero [agent is created by calling BizAppUtils.getAgentConnection (...)] which causes the NullPointerException in the above stack trace [boss.createPlatform (...,...,..., agent.getId ())].

    BizAppUtils.getAgentConnection () is essentially a block of code to check if the "IP Port string' is null or not and this string always seems to be the null value. I put some instructions to log in NewPlatformAction.java and BizAppUtils.java and have cut-and - paste a few lines of the log server below.

    Basically, BizAppUtils jump the complete code block that is supposed to create an Agent.

    I have attached a screenshot ' create new platform "UI of Hyperic and my modified source files.

    I would really like to know if I'm doing something wrong or is this a valid bug in Hyperic?

    I just want to add this IOS device to Hyperic to familiarize myself with how Hyperic manages network devices. My long-term goal is to add network devices in Hyperic via an API - so pointers (or the samples/docs) to an API which allows to add devices to Hyperic is also really useful.

    Hi Michelle,

    I was able to reproduce using a fresh installation with no agent installed.  At least one officer has, on the same machine that the HQ server is fine.  We should apply rather than just displaying this message:
    "There is no agent available to treat this platform."

    Can you install + import agent and try again?

  • is it possible to create something GarageBand for Mac and share with someone using an iOS device to be able to add and send it back?

    OK, here's the deal. I have a friend who is interested in working on musical ideas through GarageBand. He has an iPad Pro (not sure 1st or 2nd gen). and I use my 6 + or 1 Air iPad iPhone or a MacBook Pro. didn't matter that the one that I use because it can't open them with the iPad Pro, even if he sent it to me first. I am only able to open what it sends to my MacBook, although...

    Is this possible? Very convenient to add titles and the return device to added again and so on? One might think that these devices would be able to work this way with each other.

    Thank you

    GarageBand on an iOS device cannot open GarageBand for Mac projects, but a mac can open GarageBand compatible for iPhone/iPad projects.

    So, you might send your friend only mixed audio files. Your friend should add the sound to the Music.app on the iPad Pro and then add the new joint audio tracks in GarageBand. It is quite complicated, because you need to merge the titles added your friend in your original on the Mac project.

  • Cannot install iOS 10.0.1 with Apple Configurator 1.7.2

    Hello

    I have 60 iPads in 5 carts (12 per basket) that I need to install some applications on. They are already configured and supervised with Apple Configurator 1.7.2. I've never had problems in the past with AC1, I've always been able to install the updates and applications easily with very few questions, because of that I've never felt the need to update to AC2. However, this time during the update of ios and refreshment, I get the error 'complete with an error - cannot install iOS' 10.0.1 And now 12 of my iPads are stuck in recovery mode.

    I tried before wipe them off and re supervise them, but I always get the cannot install iOS 10.0.1 error, followed by all the iPads stuck in restore mode. I tried to update only 1 or 2 at a time. I tried the update/supervise them with no apps queued for installation. I tried to restore the iPad via iTunes, which works, but when I try to put it back on AC1, I still get the same error mode and recovery.

    I tried searching online for compatibility with the new iOS and AC 1 problems but found nothing.

    I would like to know if there is more information I should provide that might help.

    Thank you for your time.

    Hi Ben

    Makes your iPad successfully update to IOS 10, we have approximately 400 ipads, I've updated a single ipad at 10 IOS using our MacBook pro AC1 OSX El Capitan to test, ill try another now and see if its success.

    When you connect an ipad update the Configurator re-download the IOS 10 or use a cached copy?

    How your Configurator is connected to the internet (behind Proxy, Wifi, Ethernet), perhaps the downloaded IPSW file is corrupted and need to be redownloaded removed\.

  • keep the photos in icloud, but remove them from the iOS device?

    Hi, need help to keep my old photos in the cloud, then to remove them from my iphone device. I can also keep on my mac but still once, how can I make sure that when I delete from my iphone I can still access them in the cloud or on my big Mac? My phone is getting to the maximum it can hold up to now need to move them to a storage for later viewing device, editing or other.

    Thank you

    You cannot store pictures on iCloud and remove them from your device. Remove them on the phone also icloud removes them. You can set for storage optimized on your device that compresses the resolution of the device stored photos, keep the originals in iCloud.

    If you want to be able to todelete pictures from your phone and store them elsewhere, you must use subscription such as Dropbox cloud storage or store them on your computer.

  • Can a parent create an child (on the child device) apple ID if they don't have their own IOS device?

    I have a a question:

    My child receives a device ios as a gift, and requires an apple ID to use. However, is it possible to create an id apple of child for the child on his device, because I don't own other IOS devices.  As long as the creation of the ID child apple can be done, even if monitoring features are lost, I would be fine.

    If my child has an id apple child (or as a last resort, using mine) when they reached the age to have their OWN apple ID, all the contents of the previous ID number can then be transferred to a new one? Even if all downloaded content is FREE, all messages/emails will also be lost? It is quite confusing.

    Is anyway to transfer the contents of one ID to another? Because, as always, children are growing up!

    Any help would be appreciated! =)

    Also... it is possible to monitor an id child from a windows pc/phone apple? Just a yes/no question here.

    Thank you! (Btw, I read almost all the family sharing Guides, no outside help would be appreciated)

    An account for child (under 13 years), which can be created only in the context of a family sharing, can be created on an iPod Touch: Apple ID for your child - Apple Support and sharing of the family

    If you are not using a family sharing you must have a method of payment (credit or debit card) on your account (assuming you are the family Organizer) to pay for his purchases (if she has a balance of iTunes gift cards on his account that will be used before your card being charged).

    If my child has an id apple child (or as a last resort, using mine) when they reached the age to have their OWN apple ID, all the contents of the previous ID number can then be transferred to a new one?

    An id of the child will become a normal account when they reach the age - you have to create a new account in the future, but if you do all of its existing purchases/downloads will remain linked to its existing account, they cannot be transferred to another.

    is it possible to monitor an id child from a windows pc/phone apple?

    Depends on what exactly you want to do. You can view the purchase a history via iTunes (PC or Mac) to your computer (see your purchase history in iTunes store on Mac or PC - Apple Support), and you can view past purchases of 90 days (and possibly to contact iTunes support if there is a problem with a purchase, for example if a piece of music does not play etc) on an account via http://reportaproblem.apple.com

  • CD on laptop but not iOS devices

    I have a CD in my laptop iTunes library that does not appear on my iOS devices. My laptop says I have 6 CD of this artist, but according to my iOS devices 5. What can I do to make re - sync?

    Connect it to your computer. Open iTunes, select the iDevice icon that should appear in the toolbar area. This should display the content on the device. Select the music option. You should now see what music is installed or not. Make sure that you check the box for the CD that you want or click on the entire music library option if you want the entire iTunes music library. Then click on the option to synchronize at the bottom.

  • All iOS Devices "allow access" but will be out of sync

    Hello

    I have a 2 Air iPad & iPhone 6s, using iTunes on Windows 10.

    I always sync my devices by USB. I have not synchronized each device in a few weeks. The two iOS devices running iOS 9.3.1.

    For some reason any when I plug in a device, under Windows it warns me that 'Apple iPad' (or iPhone) is plugged in (not his name), and then on my iPad/iPhone, it asks if I want to "allow access". Neither the source device list appears in iTunes and therefore cannot sync my devices.

    I have synced with this installation of iTunes on this computer many times before, so I'm not sure why this is happening now.
    I have deleted my iTunes twice lockdown folder and restarting computer & all my devices.

    Can anyone suggest a solution?

    Thank you!

    Ash

    Problem solved. The following steps are taken:

    Reinstalled the drivers:

    Plug in Device iOS

    Open Manager devices (search in the start menu)

    Portable devices - right click on the Apple iPhone and choose Update driver software.

    Go to C:\Program Files\Common Apple Mobile Device Support and choose the Drivers folder. Click OK.

    Click next to reinstall the driver pack.

    Synchronize now works as usual.

  • I can authenticate 2FA via SMS message, but not using iOS device.

    Codes using 4-digit SMS works well, but not if I choose another option to use an iOS device, I get no messages this way. I have iPhone 6 more, but if I lost my iPhone and had an iPad, I wouldn't have no way to receive the two factor code.

    You turn on the new authentication to older two factors or two steps checking?

    Here's how you can make a difference:

    Two-factor authentication can be turn on only using parameters of iCloud on iOS devices running iOS 9 or Mac OS X running El Capitan (10.11) or later.

    Two-step verification can only be enabled when you go to the web page of my Apple ID.

    If you receive only codes by SMS, then my guess is that you are using the older two-step verification.

    First be sure that you are connected to iCloud on your iPhone and iPad using the same account that you are using for the two-step verification.

    Then, make sure you have find my activation of the iPhone on your iPhone and my iPad to find on your iPad. You will find the switch in iCloud decoration on both devices.

    Then, connect to your Apple ID account on the web page of my Apple ID. From there, you will need to check each device you want to receive codes by sending a verification code to each device.

  • Allowing Push Mail on iOS devices 9.

    It is possible to activate the push mail for iOS devices configured for a Mac OS X Server 5?  On all devices currently configured for my home server, available for this particular account pressure parameters are "Go get" and "manual".

    I have open all the ports of relevant NPP on my firewall and active certificate to the APNS on the server.  I don't know before the OS X Server 5 was not a problem.

    For the record, all devices are implemented in 'OS X Server' option in the iOS 9 for messaging, Contacts, and calendars using the.

    Hello. Yes, it works on OS X Server 5, I recently moved from Mavericks + 3 at El Capitan Server + server (Server 5.0.15) 5 via a clean install. I do not consider even the upgrade of the machine, I put an SSD in my Mac mini to replace the HARD drive, virtualized the old server during the installation of a new and set up new things.

    It really works. On the client side - various iPhones & iPads - I have no need to do something that they have been configured to push with the old server. Without knowing or enter your configuration, if I could share the standard installation and mention some specific points relating to the upgrade/migration.

    You don't need to open the ports incoming on your firewall for the service of the AFN (AFAIK) it works that way, you must of course outbound ports are open on your internal LAN (private IP address) to the Internet. I guess you have incoming ports open for IMAP secure (993) and SMTP Submission (587). The configuration of the Push Mail is not really 'push' mail to mobile devices, he said mail is there and they have to go look for him.

    Yet once, not knowing your exact Setup, I'll share with you mine who works and who is the combination of the new server + devices on existing customers.

    You have activated APN in OS X server? If you click on "Edit Apple ID..."

    You'll see this (all of my specific information has been sanitized) I do not use my own Apple ID for this, I did a 'system' Apple ID dedicated, but is not strictly required of course. Now, it is possible that you did an upgrade (new OS X Server) you need to refresh your APN certificates. I'm sure that these certificates are specific installation. Of course, in my case, I had to because I had a completely new server. Anyway, check your click on 'Manage your certificates' this will bring you to the portal site of the certificates to push Apple.

    Sign in and check your certificates.

    If things continue to not work and IF you want to reset everything you can.

    1. Disable the APN on your server.
    2. Open Keychain Access on your server
    3. Select the "Certificates" category and the system keychain
    4. Find all the APSP:(long identifier) certificates, it should be five. If you have more than five years, i.e. double game, then who will be part of your problem, the certificates that you have on your server must match those on the portal site of the certificates to push Apple.
    5. Delete all certificates
    6. Restart the server, just in case...
    7. Go to the Apple portal and revoke all certificates.
    8. Open app server
    9. Turn on Apple Push Notification (APN). Enter your Apple ID.
    10. Click on 'Manage your certificates' to connect the portal to check certificates
    11. Open Keychain Access on your server - make sure you have new certificates and their expiry date which corresponds to the portal
    12. Go to a mobile client and check. You may you touch turn off. on press settings and edit the account settings to "Refresh".

    I can advise that it works though when my situation was a little like yours has changed server and mobile clients.

  • How to use iCloud for PC without an iOS device?

    I received an invitation to join a place to share photos of iCloud.  I'm not an Apple user, do not have an iOS device (or plan in the near future).

    I've created an Apple ID iCloud and have iCloud account.  I downloaded and installed iCloud for Windows on my PC.  However when I try to run the program and enter my Apple ID and password to connect, I get the following message:

    Unable to connect

    Your identifier Apple must serve to iCloud on an OS X device or an iOS to install before you can use iCloud for Windows.

    Is this to say that I can't access the iCloud photo sharing subscription since I did not have an iOS device to set up my account?  ICloud photos can be shared with users who have an iOS device to that?

    Thanks in advance.

    You can create an Apple on a Windows PC ID, but you cannot create an iCloud account - it is a separate additional process and unless you've been able to create one on a Mac or iOS device you don't have an iCloud account, only an Apple ID. This is why the error message you see.

    iCloud accounts are essentially positioned as a way for Mac/iOS users synchronize data from their devices and are a free service at the Starter level; the control panel is intended for users of Mac/iOS, which also happens to have a Windows PC. They are not intended for Windows users only. Unless you can find a way to set up a device to iCloud on a Mac or an iOS device, you will not be able to move forward.

    iCloud sharing photos can be configured as a public or private - the first are directly accessible in any web browser, but private sharing requires you to have iCloud account. If your source is not willing to set up a public share (that would be accessible to the world in general) you will not be able to access it without an iCloud account.
