Q: Keychain error 100001 when attempting to reconnect time machine.

I upgraded on a fresh install to El Capitan (My first clean install and it will be my last!) about 3 weeks ago, a million and one issues but worked through them all except this one. I've had no Backups for 10 days on my Time Machine which gives the following warning; Keychain error 100001 occurred while creating a System Keychain entry for the username “user name” and URL “afp://user name@my_Airport._afpovertcp._tcp.local./backup”. The interesting thing here is that the backup was working better than ever and I think the problem began when I deleted the original profile "users name" once the new "user name" profile was completely active.

I have edited the keychain to no avail, used the repair keychain utility, no better, deleted the keychain completely, same error ... renamed the time machine, the backup, recreated the original profile, deleted the lot (time machine, server through airport utility) removed virus protection opened firewall.... no change still the same error. I'm no so frustrated I'm ready to toss it out the window.   No problems backing up to an old samsung drive... slow as a wet wick but toodling along nicely. So any help would be appreciated - Thanks,

iMac (27-inch Mid 2011), OS X El Capitan (10.11.1), 16GB RAM

    This procedure is a diagnostic test. It makes no changes to your data.

    Please triple-click anywhere in the line below on this page to select it:

    { defaults read com.apple.security; echo; defaults read /Library/Preferences/com.apple.security; } | pbcopy

    Copy the selected text to the Clipboard by pressing the key combination command-C.

    Launch the built-in Terminal application in any of the following ways:

    ☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)

    ☞ In the Finder, select Go Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.

    ☞ Open LaunchPad and start typing the name.

    Paste into the Terminal window by pressing the key combination command-V. I've tested these instructions only with the Safari web browser. If you use another browser, you may have to press the return key after pasting.

    Wait for a new line ending in a dollar sign ($) to appear below what you entered.

    The output of the command will be automatically copied to the Clipboard. If the command produced no output, the Clipboard will be empty. Paste into a reply to this message.

    The Terminal window doesn't show the output. Please don't copy anything from there.

    If any personal information appears in the output, anonymize before posting, but don’t remove the context.

    When you launch Keychain Access, is there an item named "System" in the list of keychains? If so, does it contain any items of the type "Time Machine Password?" Can you unlock the System keychain by clicking the padlock icon in the top left corner of the window?

    Thanks for your help so far Linc. ********* from Apple Support has also been assisting. We tried erasing the keychain, the old data keeps reappearing like a bad penny and will not allow a new entry to access time machine. We even created a new user, same error. We have no gone spent hours attempting a range of fixes and all failed with exactly the same result. We have no reached a point that the drive has been erased and a fresh install of the latest OS X attempted and this is where Michael has left me till later this evening. The install has failed once so I have sent a report to apple, erased the HDD again and am in the process of attempting the fresh install once more. I do have a copy of the previous version of OS X El Capitan on a thumb drive as a last resort.

     

    kind regards,

    Pete

    Hello Pete,

     

    Did you manage to solve this problem?

    I'm having the same issues on my Mac.

     

    Kind regards,

    Boot to recovery holding CMD+R until you see the apple logo.  You may have to select your Language on the next screen, or it may go straight to OS X Utilities.   In OS X Utilities, at the top of the screen  you have a black apple, OS X Utilities, File, Edit, Utilities.  Click "Utilities" and click "Terminal".   In Terminal, type out  /usr/bin/chflags norestricted,nosunlink “/Volumes/drivename/Library/Keychains/System.keychain”  but replace drivename with your disk name (I.E. Macintosh HD).  If you see "Invalid Flag" you typed something wrong. After it finishes, you should see a bash# command.  If so, click the black apple and click restart, then try backing up.

    Hi,

     

       I'm trying to follow this procedure, but I can't see the Volume of my hard drive mounted in /Volumes; maybe it is because the partition is encrypted. Any alternative procedure or a way to manually mount the Volume before using the chflags command?

     

    Thanks!
