IMac locked out after changing the sharing and HD permissions

Made a big mistake with my iMac internal sharing and permissions of HD.   I was experimenting with sharing and permissions of the HD info panel section in the administrator account.    In this article, I've changed the 'everyone' naming 'no access', but in doing so, it froze the machine.  Nothing did not.  I tried to restart, but after that the Apple logo and progress bar appears briefly, the screen went white.

I tried to make a backup using Time Machine, but when the time came to clear the HD and replace it with the backup TM, I got an error message saying that the system could not erase the HD.  I tried to go into Safe Mode, but he continues to send me the recovery mode.

I have a boot disc separate I made in Carbon Copy Cloner who is somewhere else right now but I can get, and maybe I can boot from that and do a total deletion of the internal HD and start again.  But I can do in the meantime?  It seems that a configuration option has locked me completely out of the HD to the iMac.

Thank you

Ed

To keep track, I tried something different. I used the option to reinstall OS X when the pane of the utility is on the rise.  My iMac then crossed the download process and reinstall OS X.  After 40 minutes, when he was all done, my machine is back with the connection, settings, and data in place.  I didn't even do a time Machine reinstall data.  Problem fixed.

Moral of the story is, don't play with fixed and permission of a lot!

  • Bootcamp (Win10) has not started after you changed the partition and updated at El Cap.

    I have a MacBook Pro (retina, 15 inches, end of 2013), 2 GHz Intel Core i7 with 8 GB of Ram.

    I had 2 system installed, Win 10 + Yosemite from the windows of beginning and the use of most of the time.

    Yesterday, I ran out of disk space and passed the partition in OS X with disk utility.

    While I changed the partition and I also upgraded to the El Cap.

  • Cannot access the network drive after trying to change the shared folder.

    I had a 80 GB drive connected to my E3000 for a few years and it worked without problem. I recently turned to a 250 GB Maxtor One Touch drive. When I plugged it, the router automatically creates a shared folder. I was able to connect to this folder without problem, but I wanted to share the whole score. When I made this adjustment and tried to save the settings, I temporarily lost access to the router. He gave me the standard page cannot be error message appears. When I got access changes seem to be made. When I try to access the drive of my laptop I get this error message, "the mapped network drive could be created", "the name specified network is no longer available". I rebooted and power rolled my router as well reconnected the drive.

    I think that since you have replaced your hard drive, old settings are configured may still on the hard drive of old. You can change the users and group so that it syncs with the new hard drive or start from scratch (reformat the hard drive).

  • After changing the port (1521 to 1525 in listener.ora and tnsnames.ora) OEM: the database is down

    Hello

    I'm installing Oracle Database 11 g 2 (11.2.0.4) on Oracle Linux 7.1.

    In short, what I'm trying to do now is changing the default port of 1521 to 1525.

    So I stopped the listener (lsnrctl stop) and then changed my listener.ora and tnsnames.ora:

    Listener.ora

    listener.ora # Network Configuration file: /u01/app/oracle/product/11.2.0/dbhome_1/network/admin/listener.ora

    # Generated by Oracle configuration tools.

    LISTENER =

    (DESCRIPTION_LIST =

    (DESCRIPTION =

    (ADDRESS = (PROTOCOL = CIP)(KEY = EXTPROC1521))

    )

    (DESCRIPTION =

    (ADDRESS = (PROTOCOL = TCP (PORT = 1525))(HOST = localhost))

    )

    )

    ADR_BASE_LISTENER = / u01/app/oracle

    tnsnames.ora

    tnsnames.ora # Network Configuration file: /u01/app/oracle/product/11.2.0/dbhome_1/network/admin/tnsnames.ora

    # Generated by Oracle configuration tools.

    BI =

    (DESCRIPTION =

    (ADDRESS_LIST =

    (ADDRESS = (PROTOCOL = TCP (PORT = 1525))(HOST = localhost))

    )

    (CONNECT_DATA =

    (SERVER = DEDICATED)

    (SERVICE_NAME = bi)

    )

    )

    And then changed the local_listener:

    SQL > ALTER SYSTEM SET LOCAL_LISTENER = "(ADDRESS = (PROTOCOL = TCP)(HOST=localhost) (PORT = 1525))";

    SQL > ALTER the REGISTRY SYSTEM;

    Finally, I started the listener (lsnrctl start) again.

    Then I tried to connect using Oracle SQL Developer to the customer. The port of 1525 works perfectly well.

    The problem is, when I open the OEM (Oracle Enterprise Manager), it says: "the database is down. Please specify the credentials of the host to access the restart and database diagnostic tools," which is like this: http://imgur.com/oKLPW65

    So I logged on the account of the host, and it shows that the database instance, listener and the agent is all down like this: http://imgur.com/Bzr84bz

    It seems that the port used by the OEM is always 1521.

    What should I do? Can someone help me solve the problem?

    Thanks in advance.

    UPDATE:

    After changing the emoms.properties & the targets.xml (thanks to Elisabeth), you will need to reconfigure dbconsole using emca.

    So what I'm doing is decreasing the config:

    $ emca - deconfig dbcontrol db-rest drop

    and then create again:

    $ emca - create config dbcontrol db-rest

    Voila.

    Best regards

    Jerry Antonius

    Hello

    Try to change the port numbers in the following files

    Don't port no 1521 to 1525

    $ORACLE_HOME /_SID/sysman/config/emoms.properties

    oracle.sysman.eml.mntr.emdRepPort = 1525 (before 1521)

    $ORACLE_HOME /_SID/sysman/emd/targets.xml

    (Before 1521)

    (Before 1521)

    LiveCycle ES4. I am trying to move a picture online with a text box to create a header.  I had to create a subform that flows to generate multiple pages of text.  After changing the settings, it seems that I can't place the images and the text I would like.  I tried moving them to the bottom, but does not work.  Is there a way to encapsulate the images so that they can be places as much as I want?

    Select your photo and text inside the subform flowed. Right-click and select wrap in subform do the positioned Subform subform. This will allow you to move objects in this subform positioned the way you like them.

  • error printhead after changing the printhead in L7680

    I have an OfficeJet Pro L7680 that is a few years old.  Recently, I have noticed a decline in the print quality for mainly black, but also a little yellow, and after changing the black cartridge with no changes, I decided to change the Black/Yellow Printhead.  So, I thought that if I'm trying to change a print head, I should change the other (cyan/magenta).  I bought new Office Depot print heads.  After replacing the print heads that I was able to print a page or two, and then all of a sudden the printer started saying there is a problem with the cyan/magenta printhead.  I tried to remove and reinstall, the suppression and power reset and then put it back up, etc, but nothing moves it.  I have not yet called HP, but I hope that when I do they will help because the print heads are under warranty until 2014, even if the printer is out of warranty.  In the meantime, I thought I would ask here is - it possible I only have a print head of DOA?  Or would it be the printer?  Unfortunately I threw the old printheads immediately (stupid me) so I can't try that goes back to the old magent/cyan print head and see what happens.

    Hello jmmarton.

    Your chip printheads were damaged by inserting wrong while the transport is always on the right side. This document provides instructions on how to replace the printhead to the unit.

  • HARD does not work after changing the disk partitions recovery media creator

    Hello world

    After installing windoows 8.1 April major upgrade (win 8.1 presents as OEM), and have shrunk C partition to create a data partition "D", "Troubleshooting" option under advanced start menu is no longer available.

    Toshiba Recovery Media Creator does not work, too (it can not find any hard disk recovery partion).
    I got in the OEM recovery partition.
    I am also able to create a recovery using the Windows tool unit.
    You have no idea about it?

    Thank you very much!

    Hello

    Sorry to hear about all this. Unfortunately, you now have a big problem. I don't understand why you didn't create support of recovery before you started to change the factory settings, including to change the structure of the partitions of HARD drive.

    Mobile offered with factory settings a structure specific partitions and recovery recorded image is saved on the partition of drive specific and marked with invisible markers. These markers are visible for preinstalled Toshiba recovery media creator tool and when you start the tool can find points of reference and has full access to specific files.

    Unfortunately, after changing the original scores structure Toshiba tool cannot find these markers more and is not able to copy files from recovery media recovery. What you need now is the original recovery disk. Using this disk, you can install original recovery image and after doing this, you will have new factory settings.

    I know it sounds stupid now but you must order the original recovery disk and it can be done on https://backupmedia.toshiba.eu/landing.aspx

    If you have any other questions you are welcome.

    I use the "feature of the paint to the text of the announcement for the pictures, but I can't understand how to change the size of the text or characters.» The 'help' in the painting says that you can do both, but they don't say HOW! Help?

    Hi PTWG,.

    If your using Vista or XP while in the painting after that you drag the text window will come the possibility to change the font and size. If you do not see this option click on view and be sure there is a check box in the text toolbar.

  • Photosmart 6520: 6520 Photosmart printer stopped printing black after changing the print cartridge

    There was a similar position two years ago. After changing the cartiridge (564XL) black printing, the printer will not copy documents. He behaves as if I placed a blank sheet of paper on the glass. I can scan the document and print the .jpeg, but not the document. The print quality of everything else is mediocre - very light on blacks, even though the colors are fine. I ran through all the diagnostic tests and he told me that the printer is fine, although the black box on the diagnostic page is empty. The difference between my printer and the one in the previous post, it's mine is 18 months and longer warranty. It has been little used. In the previous post, none of the solutions have been proposed, but apparently HP has replaced the printer. Any suggestions, or is this device intended for scrap?
