Resetting all permissions

Some how I have managed to lock myself out of everything but my startup hard drive. All external and internal drives have lock icons on them. I would like regain access to my drives and set up the permissions so that I never have to worry about permissions to get access to my other drives or networked computers.
I need to keep it simple.
Any thoughts would be greatly appreciated.

I am not sure if you already tried to do this, but if you go to the drive on the desktop, and go Apple+I (Get Info) then go down to Sharing and Permissions, you can see what permissions are designated for that drive. If you are not listed, add yourself to the list as read and write. If it is greyed out, click the lock button. Also, go to Disk Utility (Applications > Utilties > Disk Utility) and repair all permissions. This may help, it may not.

  • Can not reset all settings

    I recently updated to ios 7.0.2. on my 4S and noticed a problem in not being able to enter events on my calendar. This turned out ot be a set up problem as only the "Birthdays Calendar" was selected.
    However, in the process of troubleshooting with Apple Tech support, I was not able to use "Reset All Settings" under Settings, General, Reset.
    My four digit pass code entered for Passcode Lock when I set up the ios7 update does not allow access to "Reset All Settings" and "Erase All Content and Settings". This passcode does permit me access to the remainder reset options on the Reset page.
    Although not a problem now, if my iPhone is stolen, I would not be able to clean out my personal data.
    Any thoughts or ideas? Should I do a full Restore after backing up my data and settings? Will this force the need to enter a new pass code?

  • Problem resetting user permissions- CMD R not working

    Hi,
    Thanks in advance to those willing to lend some help!
    GEAR:
    2.53 GZ Core 2 Duo Mini running 10.8.5 All updates done.
    I believe I have a current Time Capusle backup at my disposal.
    New Macbook Air available to help.
    ISSUE:
    In the last couple of days I seem to be losing permissions to do things in my user profile which is the admin. Can't dump anything to trash without a password, mail will not open as it doesn't have permission anymore, can't move files around from folder to folder, Excel won't save as it is now read only, Firefox won't open as it thinks there is already an open version...Messages won't sync properly anymore or access address book to bring up peoples names to match the phone numbers... etc..etc.
    Research showed the problem is likely user permissions and the cure is resetting. Knowing this has to be done via terminal after a COMMAND  R boot into recovery mode I have tried everything to make this happen. No go! Apparently the partition required to boot into recovery never happened during install as the computer insists it is not there. Worse it will not default to internet recovery either. When I hold OPTION and boot I have only the HD visible and no recovery option to choose from.
    I have created a 10.8 USB recovery stick (on my mac air) and can boot to that on the mini but there is no terminal option (as far as I can see) to allow me to reset the permissions. I also tried to boot to an old Leopard CD hoping that might work.. nada.
    I have done a verify disk and repair disk permissions. All good. The computer works 100% fast and proper if I login under a new user profile so my issue appears not to be hardware related at all.
    Given that I can't CMD R into any recovery is there any other way to reset these permissions?
    Anyone know what would cause this to happen?
    Thanks!!
    Dave.

    In light of the fact there are other things Etre noted as issues I posted the lot. Sorry it's longer but thought I may lead you in the correct direction.

  • Reset Pasword - do I need to reset Directory Permissions and ACLs?

    I reset the password as described below on my mom's computer, as she forgot it.

    I did not reset Directory Permissions and ACLs.
    Do i need to do this?

    only if there was something wrong with them. otherwise this is quite independent of resetting the password and is not necessary if all you need is to reset the password.

  • System Folder errors after I changed all permissions on HD to read & write

    Hi,
    Two things may have caused probs on my new 2010 iMac (Snow Leopard), and Applecare is shut so I would really appreciate some help as I have urgent work.
    1) INCORRECT PERMISSIONS
    I have been stupid. I clicked on Macintosh HD and changed all permissions to read & write because I wanted to be sure I could open and edit all documents on other computers.
    I ran Disk Utility Repair Permissions from the install disc, but I am still getting system error messages, and my HP printer won't work.
    The first message, in Repair Permissions, said: Warning: SUID file System/Library/Cores has been modified and will not be repaired. I have read a support doc on this which says no need to worry but I don't like it and would like to fix this.
    More importantly, my HP printer won't work, displays error beside the document in print dialogue box.
    Deleting the printer and readding it didn't work, so I downloaded new drivers and tried to install them, which is when I got the second system error message: System extension System/Library/Extensions/BJUSBLoad.kext was installed improperly and cannot be used. Please try reinstalling it or contact product's vendor for an update.
    I checked the permissions on the file and they were still wrong despite Repair Permissions, allowing everyone to read & write. So I have now clicked on the entire System folder and changed the permissions to: System read & write, admin read only, everyone read only.
    Will this fix it or do I need to do something else, such as check ownership, to make sure all permissions on the computer are now correct?
    2) MEMORY STICK SHUT DOWN MY IMAC
    Additionally (though I don't think this had anything to do with my problems), I inserted a Sandisk USB memory stick the other day and it immediately shut down the computer. When I inserted it into my Macbook it initially rejected it and gave me a message saying the device wanted too much power so it had ejected it to prevent damage to my computer. When I tried again it was OK. I totally reformatted the stick in case there was something harmful on it, but should I now bin the stick as faulty? Scared to use it again.
    3) IS IT BEST TO REINSTALL ENTIRE SOFTWARE?
    If I do a reinstall of all the software from the install disc, will it wipe out all my data, such as Mail, documents, bookmarks and other apps?
    I would back-up, but if I try and back up files on my external drive it will automatically do a Time Machine back-up and I don't want to do that in case it backs-up all the corrupted files. Otherwise, I wouldn't mind starting again just to be sure all is well.
    Expert advice would be very much appreciated.
    Thank you
    Sarah

    Oh, silly really. I was in a hurry and working on docs that I needed to take to the office and open on another computer there.
    But when I checked the permissions on the doc it said I could read & write but everyone else was read only.
    I thought if I opened it on another machine I'd be stuck with read only access and not be able to work on there. I think I couldn't change it, so I thought to avoid any future problems like that I would change everything on machine!
    Yikes. Won't do that again

  • My iphone 4s has been reporting invalid sim/sim card failure intermittently for a week. tried to solve problem permanently - in mid of reset all settings my sim card failed again. help! not backed up on icloud, just itunes.  don't ask. thanks!

    my iphone 4s has been reporting invalid sim/sim card failure intermittently for a week. I thought it was a one/two-time thing, so had to manually eject SIM card and put back in.  Today, after it happened twice in 12 hours, someone told me to reset - i thought they meant reset all settings, not network settings.  while in the middle of resetting, there was an invalid SIM card again.  so a few questions - which should i do first?  try to manually back up from itunes (not connected to cloud - will be after tonight!), or eject SIM card?  don't know if one will jeopardize the other.  also, the last time i backed up was 6 days ago - have taken hundreds of pics since then - are those all lost?  is there a way to essentially not reset?  i thought the reset was okay because it said i'd lose no data or media. Help!  thanks much!

  • I have an itouch that will not let me sign in to my itunes account. The email address that it is associated with is no longer valid. I keep entering the correct password but it says that it is incorrect. I cant get a reset all of my credentials dont work.

    I have an itouch that will not let me sign in to my itunes account. The email address that it is associated with is no longer valid. I keep entering the correct password but it says that it is incorrect. I can’t get a reset all of my credentials don’t work. Now all my apps won’t work. it looks like they load for half a second then disappear. What can I do?

    - Try contacting iTunes for the password problem:
    Apple - Support - iTunes - Contact Us
    - For the other problem you can try a reset. Nothing will be lost
    Reset iPod touch:  Hold down the On/Off button and the Home button at the same time for at
    least ten seconds, until the Apple logo appears.
    - The next standard thing to do is to download/install a new app but you cant 'do that.
    - Instead, try restoring from backup.

  • I have problem with my wifi in 4 S, i cant connect to any wifi itried resetting network setting and reset all setting but the result was the same, its only keeps searching for wifi and cant find any, itried to use OTHER but also didnt work.please help me

    If Join was on then your home wi-fi must be set to Non-Broadcast.  If you did not set this up (maybe your provider did) then you will need to find the Network Name they used, and any password they used.  The SSID is Security Set ID and to see more try http://en.wikipedia.org/wiki/SSID .  Basically it is the name used to identify your router/network.  A lot of times the installer will leave it set as LinkSys, or Broadcom or whatever the manufacturer set it as for default.  Your best bet is to get whoever installed it to walk you through how they set it up, giving you id's and passwords so you can get in.  HOWEVER, if you are not comfortable with this (if you set security wrong, etc.) you would be well ahead of the game to hire a local computer tech (networking) to get this working for you.  You can also contact the vendor of your router and get help (if it is still in warranty), or at least get copies of the manuals as pdf files.  Sorry I can't give you more help, I hope this gives you an idea where to go from here to find more.

  • HELP! Resetting all setting on iphone 5, but then i tried to restart it. Not sure if its stuck or resetting

    Hi if you seen my previous post, or you might have not. My safari app isn't working and the setting for safari in setting insn't responding. I reset all setting hoping this would work and fix the problem. However, i held both the home and off button because i didn't want to do the reset anymore because i was stuck at one place for a long time. the reset with the home did happen, but the resetting all setting is still happening and progress bar hasn't move. Im not sure if its stuck or if its just taking a while.

    Hello there - I am sharing an iPhoto library across two accounts on the same computer - it works fine EXCEPT for Quicktime movies - they play on one account and claim I don't have the rights on the other - all permissions are on and ok?

    It should be in the Users/ Shared folder.
    Back Up and try rebuild the library: hold down the command and option (or alt) keys while launching iPhoto. Use the resulting dialogue to rebuild. Note the option to check and repair Library Permissions

    Can't have it both ways.  "Refreshing" w/o deleting programs and restoring to factory level are 2 different things.  Also, it depends on which OS system you have.  You did not mention this in any of your postings nor have you included your system info.
    You have to decide which do you actually want to do?
    Archive & Install (if your OS allows)
    Erase the HD (restore to factory level)

    I have got a Activation Lock on my iPhone and I need to get it activated. I don't know what Apple ID I was using with my iPhone. It shows as U***@h******.uk which is too short to be my email address. I have reset all my Apple ID passwords and none are activating my iPhone. I have also been into the apple store and they have tried to find out the Apple ID my iPhone was using but this was not successful. The serial number of my iPhone is: C32JN641DTWF

    You are going to need to change the email address you use with your old ID. Once you have got access to your old account you will then log into both accounts at the same time on your Mac and transfer your data to a single account. We can do this later, but need you to get access to your old account first.
