Unable to open any folders after PRAM reset

I have been having problems with cursor jumping to bottom of page in Firefox. I read that I should try opening in Safe mode but issue persisted.I then reset my PRAM and now I am unable to open any foldersexcept my HD and that only sporadically. I checked permissions (highlight HD>Get Info) and saw that there were 3 listings for sharing & permissions:
system, admin and everyone...all but 'everyone' had read & write. I clicked '+' to add my name but it will only give me Read Only permissions. What to do?

You may have a shot at it in starting in single user mode.
At the prompt copy & paste these commands...
*mount -uw /*
Press return
*chown root /*
Press return
*chmod 1775 /*
Press return
Then, at the prompt enter *fsck -fy*
This will run a file system check, like Repair Disk and repair any problems if it can. If you run into errors run fsck multiple times until it reports OK.
To exit single user mode type reboot.
EDIT: Also, agree with Mark... that is not a good sound...

  • Unable to open any books in iBooks after 7 download

    Unable to open any books from iBooks app after downloading new 7

    Hi, Cargei. 
    Thank you for visiting Apple Support Communities. 
    I would first start with closing all applications in multitasking and power cycling the device.  Test opening a downloaded book in iBooks
    iOS: Force an app to close

    If the issue persists, try downloading a free iBook and test to see if it opens.

    After updating silverlight, i'm unable to open any pdf files in the system

    According to your User Agent you posted this question using Internet Explorer 11 on Windows 8.1. Are you having a problem with Firefox? What Firefox version?
    You said you are having a problem opening PDF files on your system. Can you explain that better? Mozilla Support can help you with opening PDF files in Firefox, which uses a built-in PDF reader. Maybe one of these articles will help?

  • Running 10.8.3 on an Intel iMac 27'. The Finder keeps grabbing over 100% of the CPU which seems to stop me from opening any folders. Only quitting the Finder from Activity monitor resets it to normal. Any ideas?

    My Finder keeps grabbing over 100% of the CPU which seems to stop me from opening any folders.
    Only quitting the Finder from Activity monitor resets it to normal.
    Any ideas?

    Nope, I don't have a "/Users/charon/Library/Mobile Documents" directory, let alone anything underneath it. Is that like an iCloud thing or something?  I tend to avoid the Apple-supplied services when I can (I don't use iTunes either unless I can help it).
    As an update, as of about two days later this problem seems to have solved itself. Possibly sleeping and waking did something to it (though that seems unlikely given how many times I rebooted), or else there was just some long-*** kernel process that finally worked itself out.  But my system CPU is back down to normal and the cursor freezes are gone.
    ??? it is a mystery! ???

  • Cannot open any folders within thunderbird or send unsent messages after computer (ubuntu) closed suddenly whilst using programme

    I use ubuntu. The computer ran out of battery power and closed whilst I was using thunderbird. On restarting thunderbird later, I found that I could not open any folders or send any unsent messages. When I close the programme, I cannot restart it because it says thunderbird is already open, but if I use killall -9 thunderbird I am told there are no thunderbird processes running. I've checked my profile and there is no lock file or parentlock file. Someone suggest deleting the global messages database, but this hasn't helped at all.
    If I am slow responding to any questions, please be patient, tonight is my last night with a decentinternet connection - before returning to my rural African home, where we get download speeds of 15kb/s on a good day.
    Thanks,
    Karen

    Do you run some sort of anti-virus software on the Ubuntu computer?
    Do you have a backup of your profile folder? If not, now is a good time to create one.

    There might be some sort of corruption in connection with your Inbox folder.
    Try to rebuild the index file within Thunderbird:
    Right click on Inbox in Thunderbird, select Properties, and then press the Rebuild Index button.

  • HT2506 Hello I'm unable to open any pdf's with preview window opens up with message file couldn't be opened because you don't have permission to view it (none of the pdf's have any security thanks if you can assist

    Hello this week I'm unable to open any pdf's with preview, when I select to open a window opens up with message "file couldn't be opened because you don't have permission to view it" none of the pdf's have any security thanks if you can assist

    Back up all data. Don't continue unless you're sure you can restore from a backup, even if you're unable to log in.
    This procedure will unlock all your user files (not system files) and reset their ownership and access-control lists to the default. If you've set special values for those attributes on any of your files, they will be reverted. In that case, either stop here, or be prepared to recreate the settings if necessary. Do so only after verifying that those settings didn't cause the problem. If none of this is meaningful to you, you don't need to worry about it.
    Step 1
    If you have more than one user account, and the one in question is not an administrator account, then temporarily promote it to administrator status in the Users & Groups preference pane. To do that, unlock the preference pane using the credentials of an administrator, check the box marked Allow user to administer this computer, then reboot. You can demote the problem account back to standard status when this step has been completed.
    Triple-click the following line to select it. Copy the selected text to the Clipboard (command-C):
    { sudo chflags -R nouchg,nouappnd ~ $TMPDIR.. ; sudo chown -R $UID:staff ~ $_ ; sudo chmod -R u+rwX ~ $_ ; chmod -R -N ~ $_ ; } 2> /dev/null
    Launch the Terminal application in any of the following ways:
    ☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
    ☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
    ☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
    Paste into the Terminal window (command-V). You'll be prompted for your login password. Nothing will be displayed when you type it. You may get a one-time warning to be careful. If you don’t have a login password, you’ll need to set one before you can run the command. If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator.
    The command will take a noticeable amount of time to run. Wait for a new line ending in a dollar sign (“$”) to appear, then quit Terminal.
    Step 2 (optional)
    Take this step only if you have trouble with Step 1 or if it doesn't solve the problem.
    Boot into Recovery. When the OS X Utilities screen appears, select
    Utilities ▹ Terminal
    from the menu bar. A Terminal window will open.
    In the Terminal window, type this:
    res
    Press the tab key. The partial command you typed will automatically be completed to this:
    resetpassword
    Press return. A Reset Password window will open. You’re not  going to reset a password.
    Select your boot volume ("Macintosh HD," unless you gave it a different name) if not already selected.
    Select your username from the menu labeled Select the user account if not already selected.
    Under Reset Home Directory Permissions and ACLs, click the Reset button.
    Select
     ▹ Restart
    from the menu bar.

  • Unable To Open Any Files In Photoshop CC

    Hi All,
    I am unable to open any file formats in my trial version of Photoshop CC. This problem seems to occur daily and the only way to resolve it is by restarting my laptop?
    File formats I am trying to open include a new PSD file, old PSD files and also jpg files, png files and pdf files.
    I am using an HP ProBook laptop but not sure of the model number.
    Any help to prevent this from happening would be greatly appreciated and if anyone needs anymore information don't hesitate to ask me?
    Thanks

    Allyson,
    Another welcome here.
    Along with the answers to Trevor's questions, how are you attempting to Open those Image files, i.e. Dbl-clicking on them in Windows Explorer, or from the File>Open menu in the Toolbar? If you are using the former, please try the latter. If you want to work from Windows Explorer, Rt-click on the file, and choose Open With, then Photoshop.
    Your comment about WMP being the default viewing program, seems to indicate that your File Associations have been changed, with WMP now set as the target program. If this is the case, then you will likely want to go to Folder Options (check for your specific version of Windows), and reset the File Associations for, say PSD, PSB, JPEG, etc., to point to Ps.
    Good luck,
    Hunt

  • CAN'T  open any applications after mac os update 10.4.11

    CAN'T  open any applications after mac os update 10.4.11 help

    General advice on updating:
    It is worth noting that it is an extreme rarity for updates to cause upsets to your system, as they have all been extensively beta-tested, but they may well reveal pre-existing ones, particularly those of which you may have been unaware. If you are actually aware of any glitches, make sure they are fixed before proceeding further.
    So before you do anything else:
    If you can, make a full backup first to an external hard disk. Ideally you should always have a bootable clone of your system that enables you to revert to the previous pre-update state.
    Turn off sleep mode for both screen and hard disk.
    Disconnect all peripherals except your keyboard and mouse.
    1. Repair Permissions (in Disk Utility)
    2. Verify the state of your hard disk using Disk Utility. If any faults are reported, restart from your install disk (holding down the C key), go to Disk Utility, and repair your startup disk. Restart again to get back to your startup disk.
    At least you can now be reasonably certain that your system does not contain any obvious faults that might cause an update/upgrade to fail.
    3. Download the correct version of the COMBO update from the Apple download site. If your car runs on gasoline you would not want to fill the tank with diesel, so don’t try to install the PPC updater on an Intel Mac!
    The 10.4.11 Combo Updater for PPC Macs is here:  http://support.apple.com/kb/DL170
    And for Intel Macs here:  http://support.apple.com/kb/DL172
    If you prefer to download updates via Software Update in the Apple menu (which would ensure that the correct version for your Mac was being downloaded), it is not recommended to allow SU to install major (or even minor) updates automatically. Set Software Update to just download the updater without immediately installing it. There is always the possibility that the combined download and install (which can be a lengthy process) might be interrupted by a power outage or your cat walking across the keyboard, and an interrupted install will almost certainly cause havoc. Once it is downloaded, you can install at a time that suits you. You should make a backup copy of the updater on a CD in case you ever need a reinstall.
    Full details about the 10.4.11 update here:  http://support.apple.com/kb/TA24901?viewlocale=en_US
    More information on using Software Updater here:
    http://support.apple.com/kb/TA24901?viewlocale=en_US
    Using the Combo updater ensures that all system files changed since the original 10.4.0 are included, and any that may have been missed out or subsequently damaged will be repaired. The Delta updater, although a temptingly smaller download, only takes you from the previous version to the new one, i.e. for example from 10.4.10 to 10.4.11. Software Update will generally download the Delta updater only. The preferable Combo updater needs to be downloaded from Apple's download site.
    Now proceed as follows:
    4. Close all applications and turn off energy saving and screensaver.
    5. Unplug all peripherals except your keyboard and mouse.
    6. Install the update/upgrade. Do not under any circumstances interrupt this procedure. Do not do anything else on your computer while it is installing. Be patient.
    7. When it ask for a restart to complete the installation, click restart. This can take longer than normal, there are probably thousands of files to overwrite and place in the correct location. Do nothing while this is going on.
    8. Once your Mac is awake, repair permissions again, and you should be good to go!
    If your Mac seems slightly sluggish or ‘different’, perform a second restart. It can’t hurt and is sometimes efficacious!
    9. Open a few of your most used applications and check that all is OK. In this connection please remember that not all manufacturers of third party applications and plug-ins, add-ons, haxies etc, will have had time to do any necessary rewrites to their software to make them compliant with the latest version of your operating system. Give them a weeks or two while you regularly check their websites for updates. This applies particularly to plug-ins for Safari 3.
    N.B. Do not attempt to install two different updates at the same time as each may have different routines and requirements. Follow the above recommendations for each update in turn.
    Lastly, Apple's own article on the subject of Software Update may also be useful reading:
    http://docs.info.apple.com/article.html?artnum=106695
    [b]If you are updating Safari (or just have):[/b]
    Input Managers from third parties can do as much harm as good. They use a security loophole to reach right into your applications' code and change that code as the application starts up.  If you have installed an OS update and Safari is crashing, the very [i]first[/i] thing to do is clear out your InputManagers folders (both in your own Library and in the top-level /Library), log out and log back in, and try again.
    So, disable all third party add-ons before updating Safari, as they may not have been updated yet for the new version. Add them back one by one. If something goes awry, remove it again and check on the software manufacturer's website for news of an update to match your version of Safari. Remember: Tiger up to 10.4.10 used Safari 2.0.4 or, if you downloaded it, Safari 3.0.3 beta. Safari 10.4.11 used Safari 3.0.4 which was [i]not[/i] a beta. If Safari 3.1.2 on 10.4.11 is not the fastest browser you have ever used, then something is wrong!
    Moreover, trying to revert to Safari 3.0.4 (or worse still, version 2) when running 10.4.11 or 10.5 can have repercussions, as Safari 3.1.1 uses a completely different webkit on which other applications like iChat, Mail and Dashboard Widgets etc also rely, and may entail you having to reinstall an earlier operating system.
    [b][i]Most errors reported here after an update are due to an unrepaired or undetected inherent fault in the system, and/or a third party ad-on.[/b][/i] Two such add-on that have been frequently mentioned here for causing such problems are Piclens and Pithhelmet. If you have them, trash them.
    Additional tips on software installation here:
    http://docs.info.apple.com/article.html?artnum=106692
    To reiterate, Input Managers reach right into an application and alter its code. This puts the behavior of the affected application outside the control and responsibility of its developers: a recipe for  problems. That's not to say that issues absolutely will ensue as a result of Input Managers, but you, as a user, must decide. If the functionality of a specific Input Manager or set thereof is really important to you, you may well choose to assume the associated risk.
    Again, the advice is to remove all Input Managers from the following directories:
    /Library/InputManagers
    ~/Library/InputManagers
    especially prior to system updates (they can always be added back one-by-one later).

  • Unable to open any downloaded applications

    When I download a new application - today I downloaded iTunes and Quicktime - I get a dmg image, I double click on the image and I get mpkg. Double clicking on that file causes the installer app to start to open but then it immediately closes. The result is that I'm unable to open any app downloads. I've tried both Safari and Firefox and get the same result. I set up a new account and gave it Admin permissions; same result. Thoughts?

    10.4.11 seems like a bit of a disaster! At least I can boot up, but the computer seems to have difficulty with one of the internal hard drives, and will no longer sleep. Any attempt at getting it to sleep causes the second drive to disappear on rebooting; fortunately after some 10 mins it finally reappears. Not sure whether to wait for 10.4.12, or try to go back to 10.4.10, which was running fine.
