Change the password on external hard drive

Hi all

on my iMac 21.5 ", I recently updated my Mac HD internal to El Capitan 10.11.  There are now several major programs (for example MPEG Streamclip and Photoshop elements 11) which worked fine under Yosemite, but are not compatible with El Capitan.

On an external hard drive, I installed Yosemite 10.10.2 in late 2014 when it was the last version of OS X.  Only, I installed a system on the usual external drive boot on the internal HD failure.  All of these programs (also installed on the external hard drive) work very well in Yosemite.

When I start on the hard disc to access these programs, I had problems when I need to make changes for which the system requires a user and a password.  I don't remember what they were.  Is it possible to change the password (given that I can identify the user name in the "Users" folder), please?

Best regards, paulranger1.

Please open the Startup disk preferences window and select the volume on the external hard disk. You must change this selection on the internal drive after the reset of the password.

Start in recovery mode. When OS X Utilities window, select

Utilities ▹ Terminal

in the menu bar at the top of the screen, not one of the items in the OS X Utilities window.

In the window that opens, type this:

resetp

Press the tab key. The partial order you entered will automatically end this:

resetpassword

Press return. Opens a window to reset the password. Close the Terminal window to get him out of the way.

Select the boot volume ("Macintosh HD", unless you have given it a different name) if not already selected. You won't be able to do this if FileVault is turned on.

Select your username in the menu option allows you to select the account if not already selected.

Follow the prompts to reset the password. It is safer to choose a password that includes only the characters a - z, A - Z and 0-9.

Select

▹ Restart 

in the menu bar.

You should now be able to login with the new password, but will reset the keychain (empty). If you have forgotten the password for the keychain (which is normally the same as the password for the connection), there is no way to recover it.

  • I forgot my password for external HARD drive

    Hello

    Last year, I bought a USB HDD external 320.

    This external HARD drive is protected by a password. I have never changed the password, so the drive has the original password.

    I didn't use the disc about 6 months and now I put music in my iPod, but I don't remember the password. I know it is 1234 or certain numbers like that, but I can't access my disk :-(

    Everyone knows the original password Toshiba for hard drives?

    Thanks in advance

  • How to transfer iTunes with comments and followed by names, but keep the files of the song on external hard drive?

    I have all of my music stored on an external hard drive. On my old iMac, I have iTunes with all the songs on this hard drive organized or recognized as I like, with comments and play lists and track/song names and album names. How can I transfer iTunes as it is to the old iMac to the new MacMini while leaving the actual files of the song (> 2.5 to) on the external hard drive? In short, I want the old iTunes on my new computer, but the files of the song in the current HD thank you so much.

    (2.66 GHz, 4 GB RAM 20 "iMac; 2014 new Mac Mini)

    Hmmm...   Never tried, but I "think" it should work.   The reader will need to named exactly something on the new computer, as it was on the old.

    1. on the old computer, go to {user folder} / music/iTunes and move the files on the external hard drive.

    2. on the new computer in iTunes, go to Preferences > advanced and not select "copy of the file to the iTunes Media folder.

    3. always in this same window under "iTunes Media folder location", click on change.   Now select the location on the external hard drive, you have moved the files too.

    Files to be copied.

    I have a new external hard drive and when I plug it, the computer will beep, but when I open my computer, there is no indication of the letter where the external hard disk and I can't open it to see or access what is on it. He worked for some time as E drive but I can no longer access disc can someone give me a simple solution? Thanks for any help.

    I'm not an expert, but I did something similar a few times.  I remember well, I clicked on computer (in the Start Menu), selected to manage, which took me to the computer (via the "C:\Windows\System32\CompMgmtLauncher.exe" command line) Management Console.

    I hope that, when you select disk management from the Console (near the bottom of the menu under storage), you will see a list of your external drives.  Just right click on any player to get a menu which includes 'change drive... letter and access paths. ».    (You know to avoid the 'Format' unless you ready for it.)

  • Catalogue of confusion after the removal of the photos on external hard drive. [was: help!]

    I tried to be smart and I bought an external hardrive to free up some space on my laptop.  I transferred all my photos to the hardrive thought that I would be able to work on these photos in lightroom, as long as I had the hard drive plugged into my laptop.  Well this is not the case apparently.  So I imported all the photos into lightroom from the hard drive.  With the hard drive plugged into the laptop I can access all my pictures, but the catalogs that I was editing have lost all their changes.  I tried to open the backup lightroom from yesterday, and nothing happens.  If I select one of my catalogs that none of the images are there, he also says missing photos.  So I tried to locate all missing photos, and nothing happened.  All the photos are in lightroom, they appear in the library under the external hardrive.  But I can't shoot in my catalogs and cannot roll back changes to the photos I was editing when I put all my photos on the external hard drive.

    Hi Amanda,.

    You get the workflow a bit confused here. It is hard to follow all of the steps you took, but I will try to explain the correct procedure.

    1. you have a Lightroom Catalog and all images in the catalog pointing to a location on the internal drive (ideally, it would be a series of folders under the folder of a high level, to make it easier to step 3 below).

    2. copy the image of folders containing images of the Interior on the external drive. You now have two copies of your images.

    3. open Lightroom and you should see all your images again. Open the files Panel and right-click on the top-level folder that contains all the image files (this is where a single top-level folder is priceless). Choose 'location of folder update... »

    4. navigate to the top level on the external drive folder and choose that. Your Lightroom Catalog is now oriented to the external hard drive.

    At this point, you can go on using Lightroom normally. You can copy, move or delete the images of your internal drive, because Lightroom is their use is no longer.

    Note that in step 3 above, if all your image files are not contained in a single top-level folder, you will need to repeat steps 3 and 4 several times, once for each top-level folder.

  • Save the playlist on external hard drive.

    I would like to be able to export a playlist on an external hard drive, so that all the mp3s in this playlist are grouped in the same order on the hard disk as in the playlist.

    Hello Nomad vagabond,

    Thank you for using communities of Apple Support.

    If I understand your message that you want to export a playlist on an external hard drive and want to keep all the songs in the same order that they were when they were in the iTunes library. I have stopped at my music as well.

    This article contains information on the iTunes library:

    On the iTunes library files

    The iTunes Library.itl file is a database of songs in your library and playlists that you created.

    Thus, songs and playlists will be recorded how you created and you can move them to the external hard drive by following these steps:

    Manage and backup your iTunes library

    Best regards.
