After upgrade to El Capitan Time Machine does not automatically

Recently, I upgraded my Macbook Pro and iMac 24 to El Capitan.  Time Machine does not automatically work on the iMac.   I now use the backup to get a backup to run.  MacBook Pro is very well.

Thinking that this might be the associated time Capsule, I removed the disc from the Capsule and ran Spinrite on it.  Car is very good.  Then I deleted all the files on the Time Capsule and created new Time machine backups on two computers.  No problem, except the iMac not run automatically Time machine.

And yes the selection for Time Machine is configured to run automatically.

A bug in OS X 10.11.1 prevents automatic backups that happens when a desktop Mac (iMac, Mac mini or Mac Pro) is connected to a UPS (UPS) with the USB feature.

Please, back up all data before proceeding.

First, check the App Store for a later update to OS X. If it is available when you read this review, install it and see if the problem is resolved. I speak not beta versions.

Otherwise, you can work around the bug as follows.

These must be run as administrator. If you have only one user account, you are the administrator.

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

sudo defaults write /Library/Preferences/com.apple.TimeMachine RequiresACPower 0

Copy the selected text in the Clipboard by pressing Control-C key combination.

Launch the Terminal application integrated in one of the following ways:

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

☞ In the Finder, select go utilities ▹ of menu bar or press the combination of keys shift-command-U. The application is in the folder that opens.

☞ Open LaunchPad and start typing the name.

Paste in the Terminal window by pressing the command-V key combination. I tested these instructions only with the Safari browser. If you use another browser, you may need to press the return key after pasting. You will be asked for your login password. Nothing displayed when you type. Type carefully, and then press return. If you do not have a password, you will need to configure one before you can run the command. You can get a warning to be careful. Confirm. You don't need to display the warning.

If you see a message that your user name "is not in the sudoers file", then you have not logged as an administrator. Log in as one and start over.

Wait for a new line ending with a dollar sign ($) below what you entered. You can then quit Terminal.

Restart the computer and test.

  • Time machine does not take into account my partition which is case-sensitive.  Recovery has no data of this partition.

    I have a partition on my drive that is formatted for OS X Journaled, case sensitivity.  When I perform a backup, then recovery, all data in this partition is missing.  Time Machine does not recognize partitions of case-sensitive?  Strange, as the default format for Time Capsule itself is case sensitive.

    You cannot use the formatting case-sensitive with OS X. You will need to repartition the drive to Insensitive in full. You can not do any repairs or restore from a backup Time Machine.

  • Time Machine does not work after upgrade to Sierra

    The Time Machine (TM) fail to start backup and there is still "preparing backup...". "for more than an hour. This right after upgrading to Mac OS Sierra.

    Another weird thing happens to the toolbar of the Mac Mail. The Junk button is replaced by another button. trying to put back in place, but remove the button become a button.

    Please help with the backup problem mentioned above. Thank you much in advance.

    How long have you waited? After a new installation, it must be a fair while even with a SSD to prepare the first backup due to the number of modified files.

    Make sure the TM drive is in the list of items excluded from Spotlight indexing. ICloud newsletter and other cloud services.

  • Time Machine does not work after update of the Sierra

    The time function machine my Mackbook Air 2011 stopped working... it has not been saved since update for Sierra, it only take screenshots every hour, it will perform a backup is no longer on my external HD as before.

    There is no problem with the way it is implemented or the hard drive, it's me that my iMac is working perfectly since the update for Sierra and it's backup via the time machine on the same hard disk.

    It is a hard drive and put in place I was in use for about 5 years with no problems.

    Also since the update for Sierra I noticed that my MacBook Air gets hot and the fans go wild, although there was nothing or performance other than the system is auto.

    I lost the use of my built in camera after the update to El Capitan, and now I've lost the use of time machine... I was wondering if I should go back to Yosemite that everything worked well then!... is this possible?

    Thanks for any help with this!

    Update:-just so you know, time machine is to find the back up ok drive (external hard drive), it then goes to "preparing backup" and that's all, he remains in this preparation save the scene for centuries, after a while it just stops and it is saved all... nothing!

    Also noticed when I checked in Time Machine full backup I have before update for Sierra disappeared, he disappeared, been deleted... I don't know what is happening with it!

    Overall since the update for Sierra my MacBook Air did not work properly, in addition to all that Safari does not load, just to get the wheel spinning, and now (with the demise of my old back ups) it seems I can't go back to a previous state.

    My Mackbook Air took it!... the last update took the camera and really Sierra in... material not compatible with all new software, none of the new features work on my iMac or MacBook Air (only Siri), so a useless upgrade for me really, wish I didn't!

  • After upgrade to Vista, the desktop Setup does not save, but he returned each time unwanted installation

    My computer (laptop) did an automatic update of Vista. Since the restart, he lost all cookies, and all applications have behaved as if they were never used.  The files are OK. I had to reset the desktop resolution because it came with something too big. But it does not save the installation program, every time that the computer starts again (even after having his sleep), the office returns in a default setting that I don't like.  Why didn't he save properly?  I have to back to the resolution I love every time. The aspect ratio of the sidebar is also evil in this default value. The clock appears as an oval, for example. I must go to the video driver every time, set the desktop resolution seems correct.  In addition, the sidebar doesn't seem to have an option to display seamlessly, but is a big silver margin is too large for my taste.
    My office was working great before the upgrade, now he isn't very good at all.  How can I fix it so it will stay the way I like it?

    Thank you very much for your answer.  I solved this problem.  He has been
    caused by the last windows update. I think that the file was KB2524375. I have
    uninstalled and everything is back to normal. The windows update (which
    says he has been recommended by Microsoft) completely changes the configuration, disable
    Aero, etc. so changes can not be made.
    There is no error message, it was as if he superimposed a very primitive
    version of windows. Of course, I do not recommend this update.
    Anyway, it's fixed and I'm so happy!

    Thank you!

  • Time Machine does not work with Time Capsule, after update of Yosemite to iMac 2011

    My Time Capsule features all work except when trying to access files with Time Machine. It is new and can be linked to an update in Yosemite. Tried rebooting both without success.

    You can mount the drive of TC in the finder?

    The old backup Time Machine may be usable via a direct opening so the sparsebundle to give it a try.

    If not, do you want to achieve... you want to migrate your files? Have you tried the migration assistant?

  • Backup Restore Time Machine does not see RAID external drive

    Hi all

    I have a problem with my iMac restore from a Time Machine backup, and I was wondering if anyone else had the same problem already.

    I had to reinstall OS X El Capitan from scratch, based on education, I received Support from Apple. That worked without problems and my iMac works fine. However, I wanted to restore it to how it was before, using Time Machine. I keep my backups on a LaCie 5big Thunderbolt 2 and never had any problems with it.

    To restore the system, I followed the instructions on the Support page. I restarted my system in recovery mode and selected the "restore from Time Machine backup". Unfortunately the LaCie 5big does not appear on the list of drives, so I'm stuck... When you use the system in normal mode, the external RAID is visible and Time Machine stores backups on it without any problem.

    Any of you are familiar with this problem? I would be very grateful if you could help me with this problem!

    Kind regards

    Valerio

    Hello

    -While the system is booted in recovery mode, confirm that the Lacie 5big network is visible in disk utility.   You will need to disconnect / reconnect the Thunderbolt cable to the Lacie 5big be detected.

    -Once seen, a new attempt to restore from Time Machine backup.

    See you soon

  • Time Machine does not

    I'm having a problem with Time Machine.  The program seems to be backing up my files correctly but when I run the application Time Machine so I can locate a file that I need to restore, I get a black box on the screen with a date on the right scroll bar.  I have attached a picture of the screen.

    Does anyone have any suggestions?  I rebooted several times, assembled and disassembled the external hard drive but still get the same results.

    I use a 2 TB WD My Book Essential external HARD drive.  My OS is El Capitan.

    Thanks for the answers and possible solutions

  • Search for Time Machine does not work in the mail.

    Hello

    I'm trying to retrieve/view old e-mail my Time Machine ups back. I am backup on an external hard drive.

    When I get TM since the Mail, search application 'in time' does not work. If I go TM said Finder, or from the desktop, it works fine.

    I had to reinstall my OS and am trying to update on El Capitan, (thanks to the kind assistance of AppleCare!), but in the meantime I am eager to find those old emails.

    Any suggestions please? Thank you.

    Although you can restore a snapshot of Time Machine messages in the Mail application, it usually will not work with messages that were saved by an outdated version of the mail. In this case, you must use another method.

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

    ~/Library/Mail

    Right-click or Ctrl-click on the highlighted line and select

    Services ▹ Open

    the contextual menu.* should open a folder.

    Enter Time Machine and scroll to the snapshot that you want to restore from. The folder named "Mail" are subfolders named "V2" and/or "V3" (according to the version of Mac OS X that was used at the time that the snapshot was taken.) Inside of one of these subfolders are several subfolders representing your e-mail accounts. The name refers to the email addresses that you use. Select the account folders you want and then select restore... to... in the action menu (gear icon) in the toolbar of the Snapshot window. Restore the files on the desktop and not in their original location.

    Import the mailbox in the folders that you restored to the office. The imported messages appear in a new mailbox. Move those you want to keep everywhere where you want and delete the rest. Then, delete the files on the desktop.

    * If you do not see the item context menu copy the selected text in the Clipboard by pressing Control-C key combination. In the Finder, select

    Go ▹ go to the folder...

    from the menu bar and paste it into the box that opens by pressing command + V. You won't see what you pasted a newline being included. Press return.

  • Time Machine does not recognize the backups when you configure the external drive as a network drive

    I have a MyBook 5 to disk with a 1 TB partition that I used as a destination for Time Machine > 1 year now. I recently gathered the energy to connect the my book on my Airport Extreme Base Station (model 2014? the second model) to implement wireless backups. I plugged the MyBook on the base station, set up file sharing in AirPort Utility and created an account with access to the partition of TM on the MyBook under the section 'Sharing secured disk' utility.

    Now, when I open the time Machine, I choose this partition, but it does not seem to recognize that I have a string of backups already there. Then he tries to start a new backup. So a few questions.

    1. Should I abandon my old backups and start over? I don't think that I did nothing to my system in these last days that I would need to be careful, if I couldn't rely on a TM backup from that moment.
    2. Is there a way to get TM to recognize my old backups and start from there? I do not look down the barrel of a backup of time + 13.

    If 1, should I reformat the partition TM in order to start over? I don't see the older backups on disk when I look in the Finder, but I know that they are there and they are too much space. Help/suggestions appreciated!

  • Time Machine does not restore files in numbers

    I just tried to restore a file of numbers with Time Machine. I had just edited and saved.  But then I realized that I had made a mistake.  So I wanted the version that I had for a few months before.

    But even if I went back several weeks, when I clicked on restore, I got was the last version. This precedent has lost.
