Install on external device???

iTunes will not install on my external hard drive. It states it cannot install without OS X. Is there a way to install on any external device??

Yes.
To correctly move your iTunes library, copy the entire /Music/iTunes/ folder to the external.
Hold Option and launch iTunes.
Select Choose library and select the iTunes folder on the external.
You can the delete /Music/iTunes/ folder on teh internal drive.

  • Where would I find the drivers for an external device after I install it?

    Okay, so I need help. I installed a driver for osx 10.5 thinking that installing the software 10.7 would support it. If it did, then it created a bigger problem, which is I cannot create a USB Ethernet connection in the networks pane. Mind helping out and telling me what I should do?

    you would generally find the drivers for an external device on the manfacturers website.  However, with printers for example, I have recieved updates directly through Software Update.

  • I am having one application which i am going to install on my ipad and i am having one external device having USB interface. I want to have communication in between  my device and ipad over USB/BT. is it possible

    My external device is having male USB connector. The cable available in market are having can be plugged to the device having female connector.I will need converter in between as my device is having male connector. Can i get such cable? If yes can i establish communication in between my app and device over these cables.I am not passing any audio/video data or photos.I am sending data frames. My device is having firmware and it sends data frames in firmware understandable format. Let me know can i have two way communication in between over USB/BT?
    Right now i am connecting my device with host PC and i want to replace my host PC with ipad.

    Thanks....
    will it be possible to establish communication in between my device and app. Because camera conection kit only transfers photos and videos and my device doesnt have any audio/video data.
    If yes, should i add photo header to my frames and will send as corrupted photo file or what needs to implement so that i can have sound communication in between.

  • No audio out on internal speakers or headphones from external device

    I'm using an intel iMac 17" I tried to plug in an external cassette deck, and listen to it through the internal speakers. Even though all system prefs for audio work as expected, and I can see the audio meters on screen operating, nothing will induce it to play sound either through the internal speakers, or headphones.
    The audio is certainly going in there, as it recorded perfectly in iMovie. The internal speakers work perfectly for alerts, iTunes, the web, everything. But no external device will work.
    I've tried an iPod, a microphone, and a cassette deck, all with the same result. I've launched Garage Band as this can upset the midi player, but it's fine. I've visually checked the settings, no problem.
    As an alternative I also tried an iMic and stopped using the jack input on the iMac. Still nothing. I plugged headphones into the iMic, nothing. No audio will play unless it's already on the Mac. External audio goes in there and dies before it reaches the speakers.
    All the visual info I get in the sound panel regarding connection options, output etc, is exactly as expected, I just can't get any audio at all.
    Does anyone have any suggestions? There's only a few day's warranty left...
    Many thanks.

    Hello David,
    Thanks for the pointer. I looked at the website for Linein, and I already have Audio Hijack pro installed, which contains this application. When I ask AH to record the system audio, the volume meters are dead, I hear nothing, and record nothing - unlike iMovie.
    When I do ask it to record, I can hear a thumping sound from the Mac speakers, but nothing else.
    I'm really desperate for a solution to this; I can't understand why it's so hard to achieve. If it was just the line in socket I'd suspect that, but a USB connection as well? I don't understand that at all.

  • HD-DVD won't play on Satellite P200-123 Unable to output to external device

    Hi,
    I bought a P200-123 yesterday. One of the first things I tried after the Vista installation initially completed was running an HD-DVD. I know the disc is fine as it works in my Xbox 360. Unfortunately, it didn't work with the supplied HD-DVD player software - the play icon lights up and then I get this error message:
    "Unable to output the video to an external device. Please switch your display device by pressing the Fn + F5 keys after ending the application."
    I don't have an external display connected to the laptop. I tried different discs but all gave me the same error. I then carried on updating drivers and installing a bunch of Windows updates. I repeatedly tried the HD-DVD player throughout the countless updates and reboots but I always get the same error. Out of frustration I bought PowerDVD Ultra. That plays the movie for about one second before giving me an error:
    "Cannot initialize secure display session - (Error Code = 0122)"
    The error dialog goes on to say that the error could be caused by an incompatible graphics driver or beccause I'm using a dual-monitor setup. The reference to dual monitors is common to each player application so I'm wondering if the problem is in that area. I haven't connected a secondary display but when I look at the standard Windows display properties dialog or the ATI Catalyst control center app I can see a disabled secondary display. I'm assuming that's normal - there's no obvious way to remove the disabled secondary display.
    Can anyone help me get HD-DVD playback working?
    Thanks,
    Ian

    Thanks for the reply. Yeah, I downloaded that and tried it yesterday but it didn't help :-(
    I noticed that a couple of other unrelated things stopped working after the last batch of Windows and Toshiba updates - for example, the Event Viewer snapin wouldn't load and the built-in .NET Framework 2.0 installation appeared to be corrupt until I ran sfc to repair it. I was getting pretty sick of the whole thing so I took the drastic step of nuking the C: drive and installing Vista Ultimate from my own retail DVD.
    One hour later I have a working Vista Ultimate installation and, interestingly, I installed the Toshiba HD-DVD player and it now works!!!
    It was a pretty drastic method to get it working - and not everyone is going to have a retail copy of Vista just lying around - but at the moment everything looks good. I still don't understand the original root cause (or which software update messed up Event Viewer/.NET Framework) but I guess it's kind of a solution...

  • Fire Wire: MBP OS X.4.11 Can't see external devices. PLEASE HELP!

    Fire Wire: MBP OS X.4.11 Can't see external devices. PLEASE HELP!
    My MBP will not "see" my new MB or my back-up drive—both connected via a firewire 400 (6 pin) cable. Both running Tiger X.4.11
    I have used this cable to connect my MBP and a TiBook in the past as well as to back-up onto the LaCie e-drive.
    I have run "disk repair" and "permissions" on both machines.
    BTW—"permissions" are regularly out of wack on the MBP. But, the disk is OK according to Disk Utilities.
    I also cannot put the machine to sleep after logging out. Has a hard time shutting down as well. Sometimes I need to force a re-boot.
    Can't run Disk Doctor because I don't have a bootable disk yet. It's coming via snail mail.
    The new MB "sees" the e-drive connected with the same cable.
    I can't transfer my files to the new MB nor can I back up.
    Is it time for a "clean install"? Makes me nervous that I cannot backup before trying anything drastic.
    Can someone please help me?
    Thanks in advance.
    Tek

    Put the more recalcitrant computer into Target Drive mode by starting it with the T key down until you see the yellow on blue screen. Then connect it to the other machine by firewire cable while both are already awake.
    I hope that you did not do any upgrades while you had external drives connected... that is an automatic problem. Always disconnect from externals and accessories before doing any upgrades. Always back up before doing any upgrades.
    Firewire networking is not the same as using a computer in Target Disc mode. In Target disc mode, you are using the internal drive of the Td computer as an external. That should allow you to run disk utility. Do use the proper disc utility version for the OSX version that is on problem drive. ie don't use the Leopard disc utility for the Tiger disc or vice versa.

  • Audio to midi error - check conflict with external device - apogee rosetta

    hey there
    i have a problem and any help is much appreciated..
    basically i am running a quad xeon dual 2.66 machine under 10.4.10 and using logic 7.2. 1 gig ram.
    i am using a apogee rosetta 800 with the option x firewire card for my audio interface.
    whenever i set a track up to record and 'play' logic i get a message saying,
    'unable to sync audio to midi check conflict with external device' and then it says something like sample rate 43021 recognised.. something close to 44100 but not quite..
    so i think my problem is a clocking/sync one maybe? i have tried everything i could think of, including fixes suggested on the forums here, but nothing so far seems to help e.g making sure autosync in on the transport is unchecked, checking audio MIDI setup.
    worryingly with the few problems similar to this on the forums there doesn't seem to be a way to fix it!!
    anybody who could help would be a lifesaver.. this is destroying my workflow!! emailed apogee and im waiting for a reply.
    thank you very much
    richie

    Hi,
    Ok, then there can be a few more possibilities,
    Try this: unplug your Rosetta, and any other FireWire devices you might have. Basicallly you want to start Logic with the internal audio.
    If this works ok, then it is not an issue with the Mac's hardware, and is an issue with a FW device.
    Then, quit Logic, and plug in the Rosetta by itself. Boot Logic, and select it as the audio interface. Try playing stuff back. does it work? If yes, then the issue is with another FW device. If there is a issue, then there might be a corrupt driver, a bad FW cable, etc. Keep trying one by one to go through re-installing the drivers, and also try changing the FW cable. If this still does not solve it, there might be an issue with the Mac OS 10.4.10. You might need to install Pro App support 4.0. Also, there was a fix available from Apple not so long ago specifically for FW audio devices. Please do a search in Apple's suport site for "FireWire audio device" and see if you find the patch.
    If the Rosetta works when it is the only FW device hooked up to the Mac, then you have a conflict with another device, like a FW hard drive, etc... check each one until you find the culprit.
    Cheers

  • Connecting  external device (scanner & fax ) to my SAP system

    HI ,

    Hi Divya,
    based on your description I think that maybe the forum Process Integration (PI) & SOA Middleware would be a better place for discussing this kind of requirement.

  • Does using two bus powered external devices MacBook Pro 13" put too much strain on the power supply?

    Will daisy chaining two bus powered external devices put too much strain on my 2011 MacBook Pro 13" power supply?  Specifically I would like use ProTools with a LaCie bus powered hard disc and a Digidesign Mbox 2 Pro which is also bus powered with firewire.

    Hi rrlavigne,
    The biggest difference between the two machines in maximum RAM capacity. The white MacBook is limited to 4GB, whereas the MacBook Pro will support 8GB of RAM. While the cost of RAM is prohibitory right now (to go to 8GB), to have that flexibility in the future will very much be worth it... especially considering you intend to install Logic.
    Other than that, I think in terms of "raw performance" the machines are very equally matched. You're paying for the unibody design, backlight keyboard, SD card and new battery technology for that $200 premium (in addition to the slight CPU bump).

  • External device connection: RFC Server?

    Hello to all,
    i'm new here.
    I'm facing a new problem i never met before.
    I'm on a 4.7 enviroment and i have to interface sap with an external device.
    The producers of external device, release an executable file that makes (but i don't kwnow how) the communication from the device and sap.
    The only things that i had to do was (following the device documentation):
    1. Create a tcp/ip remote destination that point to one external executable (es: Z_EXT_DEVICE --> c:\device\device2sap.exe) (if i double-click on it, it don't do anything) 
    2. Setup in the external setup device program (setupdevice.exe), the name of the RFC destination (Z_EXT_DEVICE), the sapgateway address (sapgw00) and the sap host address (ex 10.2.4.XX)
    (Note that i don't have to specify sap usr/pwd for the connection in any step).
    3. Call a simple function module in SAP system in this way:
    CALL FUNCTION 'Z_RFC_DATA' DESTINATION 'Z_EXT_DEVICE'
        EXPORTING
          header        = szheader
          data          = szdata
          status        = '0'
          data_len      = szvalue
        IMPORTING
          system           = szretsystem
          code             = szretcode
          ret_text         = szrettext
          header           = szanswerheader
          len_data         = szlendata
          bct_status       = szstatus
          bct_data         = szanswerdata
        EXCEPTIONS
          communication_failure  = 1
          system_failure         = 2
          OTHERS                 = 3.
    The code of the function module is empty :
    FUNCTION Z_RFC_BCT.
    ""Lokale Schnittstelle:
    *"  IMPORTING
    *"     VALUE(HEADER) LIKE  BAPIRET2-MESSAGE
    *"     VALUE(DATA) LIKE  BAPIRET2-MESSAGE
    *"     VALUE(STATUS) LIKE  BAPIRET2-MESSAGE
    *"     VALUE(DATA_LEN) LIKE  BAPIRET2-MESSAGE
    *"  EXPORTING
    *"     VALUE(SYSTEM) LIKE  BAPIRET2-MESSAGE
    *"     VALUE(CODE) LIKE  BAPIRET2-MESSAGE
    *"     VALUE(RET_TEXT) LIKE  BAPIRET2-MESSAGE
    *"     VALUE(HEADER) LIKE  BAPIRET2-MESSAGE
    *"     VALUE(DATA) LIKE  BAPIRET2-MESSAGE
    *"     VALUE(LEN_DATA) LIKE  BAPIRET2-MESSAGE
    *"     VALUE(STATUS) LIKE  BAPIRET2-MESSAGE
    *"  EXCEPTIONS
    *"      COMMUNICATION_FAILURE
    *"      SYSTEM_FAILURE
    ENDFUNCTION.
    After the call of the function module in sap system, magically the importing variables are filled all by values read from the external device. At this point I'd like to ask u some questions :
    1. I think that external device program (device2sap.exe) is an RFC server program. Is it right ??
    2. How the connection from external executable and sap works if i don't specify usr/pwd in any configuration file? The device    infact, work with every sap (if u execute the three sinple step wrote before)
    3. I'd like write a server like that for a different external device. In the old release of sap (4.0,4.5) there was a sap tools (in function module editor SE37) that permitted (starting from a function module), to generate a client or server external program (in C or VB). In 4.7 this functionality is missing. Is there other sap tools that permitt to do the same thing or this functionality is completly lost?? In the second case, do u have some hits that could help me in this step??
    4. I'd like to have some documentation about the server program and communication methos between external RFC server program and Sap. Where i can find some good documents that could help me in that task ??
    5. I heard about DCOM connector. Where i can find some good documentations that explain how is it , how it works and if it could solve my problem ?
    Thanks a lot in advance.
    Andrea

    Hi, I'm sure the device2sap.exe is developed by a Connector Tools. E.G. .Net Connector, Jco and so on.
    So reply your question as following:
    1. Yes, in the external application side, it can simulate a RFC server for the SAP to call, just like call to another R3 server.
    2. No need on use/pw. it is not DataBase connection, just a RFC connection. The key feature only need is the IP. And you should configure the RFC destination using IP. RFC is a FM call protocol, not to access a DB.
    3. Using the Connector tools I mentioned in the former reply. And you can navigate in the .Net Tech Forum in SDN.
    4. The guide of Connector Development can be get from SDN, and some sample code will be copy in the install directory, after you installed it.
    5. DCOM is the tech used in the former Connector version SAP DCOM conncetor. Now, as the windows is into the Dotnet Time, recommand you to use DotNet Connector.
    That's all.   hope it will be helpful

  • I have a mac os 10.5.8, i want to upgrade to mac os snow leopard, can i keep all my files (documents, music on itunes) without backing up all the files first on a external device prior to the upgrade?

    I have a mac os 10.5.8, i want to upgrade to mac os snow leopard, can i keep all my files (documents, music on itunes) without backing up all the files first on a external device prior to the upgrade?

    I strongly advise against upgrading the OS without first making a backup. Were something to go wrong you would lose all your files without the backup. See:
    How to Install OS X Updates Successfully
    A. Repair the Hard Drive and Permissions:
    Boot from your current OS X Installer disc. After the installer loads select your language and click on the Continue button. Then select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list.  In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive.  If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer. Now restart normally. 
    If DU reports errors it cannot fix, then you will need Disk Warrior (4.0 for Tiger) and/or TechTool Pro (4.5.2 for Tiger) to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
    B. Make a Bootable Backup Using Restore Option of Disk Utility:
    Open Disk Utility from the Utilities folder.
    Select the destination volume from the left side list.
    Click on the Restore tab in the DU main window.
    Check the box labeled Erase destination.
    Select the destination volume from the left side list and drag it to the Destination entry field.
    Select the source volume from the left side list and drag it to the Source entry field.
    Double-check you got it right, then click on the Restore button.
    Destination means the external backup drive. Source means the internal startup drive.
    C. Important: Please read before installing:
    If you have a FireWire hard drive connected, disconnect it before installing the update unless you will boot from this drive and install the update on it. Reconnect it and turn it back on after installation is complete and you've restarted.
    You may experience unexpected results if you have installed third-party system software modifications, or if you have modified the operating system through other means. (This does not apply to normal application software installation.)
    The installation process should not be interrupted. If a power outage or other interruption occurs during installation, use the standalone installer (see below) from Apple Downloads to update.  While the installation is in progress do not use the computer.
    D. To upgrade:
    Purchase the Snow Leopard Retail DVD.
    Boot From The OS X Installer Disc:
    Insert OS X Installer Disc into the optical drive.
    Restart the computer.
    Immediately after the chime press and hold down the "C" key.
    Release the key when the spinning gear below the dark gray Apple logo appears.
    Wait for installer to finish loading.
    E. If updating:
    Download and install update(s) 
    Use Software Update, or
    Download standalone updater(s).

  • Restored iMac from an MBP Backup giving problems with external devices

    Recently, I restored from an MBP Leopard OS Time machine Backup into a new iMac 27".
    Restoring process ran smoothly and took like an hour to recover my files and applications from the external disk time machine backup and after that the new iMac had everything my old MBP used to have but the OS. So far so good.
    But now I'm having problems connecting external devices, like the very same external disk to set my time machine backup or a Cannon Printer.
    The iMac can recognize and attach the external HDD (iOmega 1TB), I've succesfully formated it several times, but as soon as the backup process starts it will idle after backing 200MB or so and the HDD will be abruptly disconnected.
    Regarding the MP610 Cannon printer/scanner I used it smoothly once from this iMac, but after that it's been impossible to scan or print again, and it keeps saying it is connected to an MBP instead of an iMac!
    I already read the other related topics but my case is slightly different than those, so I will appreciate anyhelp you could provide me.

    When you say you restored, what does that mean? Did you do a full restore, installing the system from the backup onto the iMac? If so, you've probably borked the system and will have to reinstall it. See:
    http://support.apple.com/kb/HT2186
    Also, if you restored applications, it's possible some of those applications are not installed correctly or are not compatible with SL. Printing problems are common among folks who have not updated printer drivers to SL-compatible versions.

  • Can I make combo drive into an external device?

    Okay, so I have a 14" iBook G4 1Ghz with a bad combo drive. I purchased a replacement from Amazon but then I looked up the directions for installing it and I am not sure I want to go through all of that. So, I have the following questions:
    Is it possible to make a CW-8123-C combo drive into an external device? If so where can I get the case that would be compatible with that?

    I'd do a google search for "slimline optical drive enclosure." I actually just did one and a fair number came up for USB, but I didn't see any for firewire. They're out there, but you'll probably have to hunt for them.
    If worse comes to worse and you need to do something like reload the OS, and you have access to another Firewire Mac (remember, firewire 400 ports aren't available on all Macs any longer) you could always do the following:
    1. On the borrowed Mac, put the optical media into the optical drive, and let the OS load it.
    2. Connect a firewire cable between your Mac and the borrowed mac.
    3. Reboot the borrowed Mac in target mode.
    4. Reboot your own Mac, holding down the "alt/option" key. The screen will turn blue and in about a minute or so, the drives on your system as well as the hard drive and optical disk on the borrowed system will show up as bootable devices.
    5. Select the optical drive by clicking on it then clicking on the icon that looks like a right arrow.
    The system will boot off the optical drive on the borrowed system, but you'll be able to do stuff like use disk utility to repair your volume, change passwords, etc. Just make sure you're doing this to YOUR disk and not the disk on the borrowed system.
    When you put a Mac into target mode, it really just turns the computer into one big firewire interface to the computers drives whether they be optical or hard disk.
    It's obviously not the most convenient way to do stuff but in an emergency it can do the trick.
    Hope this helps.
