What is the cause of my recent refresh and sync problems?

I use my iBook for my iTunes and iPod. I have my library on an external Iomega eGo connected by firewire. I leave the iTunes up pretty much all the time with an hourly check/update of the podcasts.
After work, I will come home and connect my iPod via USB cable to my iBook. When the screen comes out of "sleep", it will say it is sync-ing but the spinning cursor will be on the screen. When I get up in the morning to sync my iPod again and head to work it will still be spinning and will have done nothing. I have begun to check it before connecting the iPod in the evening and on occasion the cursor will be spinning. I have tried force closing iTunes either through trying to shut down or just force closing in the OS - neither works. I just get a message that the force close failed. I end up having to turn off the machine to get it to reset.
What is wrong?

First, you should update to -> 10.4.11 and see what happens.

  • What is the cause of Firefox seizing up and having to use task manager to close down

    When I use Firefox within 2 pages it seizes. When you try to click on anything I hear a ding with no response, even when you try to shut it down. You have to shut it down with Task manager. I have uninstalled it and reloaded but the same thing happens. When I use Explorer I have no troubles. I need Firefox as a site that I use only works with Firefox. This problem has occurred after the recent upgrade

    Start Firefox in <u>[[Safe Mode|Safe Mode]]</u> to check if one of the extensions or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance/Themes).
    *Don't make any changes on the Safe mode start window.

  • Have to keep refreshing Firefox to see messages received on Facebook, and videos do not play in Firefox 3.6.9. What's the cause?

    While on Facebook, I always need to refresh the page to know I received a message, comment or whatever else. Also, while on game sites such as Gamespot, Firefox does not play any videos. All this is happening in version 3.6.9. What is the cause for this?

    How ram does your machine have have you tried shut the machine down pull the power plug for a few minutes and plug it back in and restart the computer.  The only thing I can think of is Low onn Ram or the speed of your connection. It might be the player you are using as well. download VLC Player itwill play everything.

  • What are the cause and fix for the following error message? NS_ERROR_FILE_ACCESS_DENIED failure code: 0x80520015

    Every time I close my Firefox browser I receive the following error message (see details below).
    FYI:
    -- I am running the current version of Firefox.
    -- I had no problems with this error message until my computer was recently attacked by 2 viruses:
    ` SystemFix
    ` Win7 Antivirus 2012
    Both viruses have since been cleaned from my computer. However, I am still receiving this error message.
    Here are my questions:
    * What are the cause and fix for this problem?
    * Do I need to uninstall and reinstall Firefox?
    * Is it possible that this error message is related to an add-on and that it has nothing to do with the recent virus attacks?
    I look forward to any feedback and support you might be able to provide.

    Try:                                               
    - iOS: Not responding or does not turn on           
    - Also try DFU mode after try recovery mode
    How to put iPod touch / iPhone into DFU mode « Karthik's scribblings
    - If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.
    - Try another cable       
    - Try on another computer                                                       
    - If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

    First part of your question:
    Error Message
    %CFT_API-3-CFT_ERRMSG_NO_MEMORY: [chars] [chars] [dec]
    Explanation
    The system was unable to supply the requested memory for flow processing to continue
    Recommended Action
    Reduce other system activity to ease
    memory demands. If conditions warrant,
    upgrade to a larger memory configuration.
    link:
    www.cisco.com/c/en/us/td/docs/ios/system/messages/guide/sm_cn02.pdf
    Pretty generic, but its a start, the process in question is cft_flow_lookup.
    This may be an indication of a deeper resource issue.

  • What is the cause of the Spinning Wheel of Death (SWOD) and how can we fix it?

    What is the cause of the Spinning Wheel of Death (SWOD) and how can we fix it?
    I get the SWOD using Safari, Mail, Google chrome, Firefox, Mathematica, and other programs. This cannot be a browser plug-in issues as other forums suggest. I suspect a windows process at the root but I don't enough to know how to trace. Does anyone know what's causeing this epidemic? 

    I'm having a similar problem. Someone PLEASE HELP!
    I'll start with just an example of what I've been facing. During the composing of this post, when I switched from Firefox to Word, I had to wait 60 seconds before the spinning wheel stopped and I got a cursor. I then copied one set of Etrecheck results, switched back to Firefox, hit Command-v to paste and had to wait 45 seconds or so for the spinning wheel to stop. And the paste operation didn't paste until I hit Command-v again (with no wait this time).
    Here's what I've done:
    I tried three times to run a scan with avast! and all three times the scan was unable to complete.
    I restarted holding down Command-r and it found and fixed many permissions, but found no problems with files.
    I ran Etrecheck in a "Safe Boot" and in a normal startup and there were two things that were tagged as "[failed]" in the normal startup:
    Launch Agents: [failed]com.logmein.LMILaunchAgentFixer.plist Support

    I apologize for taking up so much space, but here are the results from both Etrecheck runs:

  • What is the cause for the mac to become slow

    what is the cause for the mac to become slow?

    Things You Can Do To Resolve Slow Downs
    If your computer seems to be running slower here are some things you can do:
    Start with a visit to: OS X Maintenance - MacAttorney.
    Boot into Safe Mode then repair your hard drive and permissions:
    Repair the Hard Drive and Permissions Pre-Lion/Mountain Lion
    Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list.  In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive.  If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
    If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
    Repair the Hard Drive - Lion/Mountain Lion
    Boot from your Lion Recovery HD. When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list.  In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive.  If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported, then click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu. Select Restart from the Apple menu.
    Boot to the Recovery HD:
    Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
    Restart your computer normally and see if this has helped any. Next do some maintenance:
    Suggestions for OS X Maintenance
    For situations Disk Utility cannot handle the best third-party utility is Disk Warrior;  DW only fixes problems with the disk directory, but most disk problems are caused by directory corruption; Disk Warrior 4.x is now Intel Mac compatible.
    OS X performs certain maintenance functions that are scheduled to occur on a daily, weekly, or monthly period. The maintenance scripts run in the early AM only if the computer is turned on 24/7 (no sleep.) If this isn't the case, then an excellent solution is to download and install a shareware utility such as Macaroni, JAW PseudoAnacron, or Anacron that will automate the maintenance activity regardless of whether the computer is turned off or asleep.  Dependence upon third-party utilities to run the periodic maintenance scripts was significantly reduced since Tiger.  These utilities have limited or no functionality with Snow Leopard or Lion and should not be installed.
    OS X automatically defragments files less than 20 MBs in size, so unless you have a disk full of very large files there's little need for defragmenting the hard drive. As for virus protection there are few if any such animals affecting OS X. You can protect the computer easily using the freeware Open Source virus protection software ClamXAV. Personally I would avoid most commercial anti-virus software because of their potential for causing problems. For more about malware see Macintosh Virus Guide.
    I would also recommend downloading a utility such as TinkerTool System, OnyX 2.4.3, or Cocktail 5.1.1 that you can use for periodic maintenance such as removing old log files and archives, clearing caches, etc.
    For emergency repairs install the freeware utility Applejack.  If you cannot start up in OS X, you may be able to start in single-user mode from which you can run Applejack to do a whole set of repair and maintenance routines from the command line.  Note that AppleJack 1.5 is required for Leopard. AppleJack 1.6 is compatible with Snow Leopard. There is no confirmation that this version also works with Lion.
    When you install any new system software or updates be sure to repair the hard drive and permissions beforehand.
    Get an external Firewire drive at least equal in size to the internal hard drive and make (and maintain) a bootable clone/backup. You can make a bootable clone using the Restore option of Disk Utility. You can also make and maintain clones with good backup software. My personal recommendations are (order is not significant):
      1. Carbon Copy Cloner
      2. Data Backup
      3. Deja Vu
      4. SuperDuper!
      5. SyncTwoFolders
      6. Synk Pro
      7. Synk Standard
      8. Tri-Backup
    Visit The XLab FAQs and read the FAQs on maintenance, optimization, virus protection, and backup and restore.
    Additional suggestions will be found in Mac maintenance Quick Assist.
    Referenced software can be found at CNet Downloads or MacUpdate.
    Additional Hints
    Be sure you have an adequate amount of RAM installed for the number of applications you run concurrently. Be sure you leave a minimum of 10% of the hard drive's capacity as free space.
    Add more RAM. If your computer has less than 2 GBs of RAM and you are using OS X Leopard or later, then you can do with more RAM. Snow Leopard and Lion work much better with 4 GBs of RAM than their system minimums. The more concurrent applications you tend to use the more RAM you should have.
    Always maintain at least 15 GBs or 10% of your hard drive's capacity as free space, whichever is greater. OS X is frequently accessing your hard drive, so providing adequate free space will keep things from slowing down.
    Check for applications that may be hogging the CPU:
    Open Activity Monitor in the Utilities folder.  Select All Processes from the Processes dropdown menu.  Click twice on the CPU% column header to display in descending order.  If you find a process using a large amount of CPU time, then select the process and click on the Quit icon in the toolbar.  Click on the Force Quit button to kill the process.  See if that helps.  Be sure to note the name of the runaway process so you can track down the cause of the problem.
    Often this problem occurs because of a corrupted cache or preferences file or an attempt to write to a corrupted log file.

  • TS3694 What is the cause of "error 1015" when trying to restore and update an iPhone 3gs?

    What is the cause of "error 1015" when you're trying to restore and update an iphone 3gs? My iphone is currently in recovery mode and can not get out of it. All the information about my iphone shown on itunes is only marked as- N/A. How can I get my iphone out of recovery mode and get it to recover and update?
    Thank you,
    MacQuestioner3

    http://support.apple.com/kb/TS3694#error1015, which says:
    Error 1015: This error is typically caused by attempts to downgrade the iPhone, iPad, or iPod touch's software. This can occur when you attempt to restore using an older .ipsw file. Downgrading to a previous version is not supported. To resolve this issue, attempt to restore with the latest iPhone, iPad, or iPod touch software available from Apple. This error can also occur when an unauthorized modification of the iOS has occurred and you are now trying to restore to an authorized, default state.
    In other words, either your phone is jailbroken and you are sadly out of luck or you are trying to downgrade iOS.

  • HT1819 I noticed that some of my podcast are missing from the iTunes store. What is the cause of that?

    I noticed that some of my podcast are missing from the iTunes store. What is the cause of that?

    That suggests that the tracks are damaged.
    If your country's iTunes Store allows you to redownload purchased tracks, I'd delete your current copies of the dodgy tracks and try redownloading fresh copies. For instructions, see the following document:
    Downloading past purchases from the App Store, iBookstore, and iTunes Store
    Otherwise, I'd report the problem to the iTunes Store.
    Log in to the Store. Click on "Account" in your Quick Links. When you're in your Account information screen, go down to Purchase History and click "See all".
    Find the items that are not playing properly. If you can't see "Report a Problem" next to the items, click the "Report a problem" button. Now click the "Report a Problem" links next to the items.

  • What is the cause of corrupt preferences?

    I manage two macintosh computer labs and a number of windows based labs for a small liberal arts college. Lately, we have been encountering a surprisingly large number of students and faculty members who seem to have corrupt preference files for multiple applications and I am having trouble determining the cause. The common applications encountering these problems have been Flash MX, Swift 3D, and Final Cut Pro.
    In each case, trashing their preferences and then relaunching the application resolved the issues. While this is an easy fix, the problem has been rather troublesome for our instructors and students.
    I have tried explaining the removal of corrupt preferences to the instructors so they can perform it themselves if it is interrupting their courses, but they feel it is my job to do that and not theirs. I find it a little embarrassing to frequently be called into their classrooms for a 20 second fix and I'm sure they find the situations irksome and perhaps embarassing as well.
    If at all possible, I would like to try to determine the cause of these corrupt preferences and take whatever actions may be available to try to prevent them from occurring as often, but I do not know where to begin.
    Our setup:
    An XServe running OS X Server 10.4.7 and Open Directory and AFP services.
    An XRAID hosting all of the students' and faculty members' home directories.
    Client computers, one lab Power Mac G5s and one lab Power Mac G4s, all with Mac OS X 10.4.7 on them. All users authenticate using OD accounts and remote home directories on AFP shares.
    The image on the computers is the same image that was deployed at the beginning of this school term (back at the end of August) and has not been changed since. I'm not sure what could have changed that would have increased the likelyhood of preferences becoming corrupted.

    As far as I know, its buggy software. If your school has an Apple tech support contract, you might try calling or emailing Apple to ask about this problem.

  • What is the condition for fetching "Recently Created Opportunities" list

    Hello All,
    I need to know ,What is the condition to fetch "Recently Created Opportunities" list from Opportunity Home Page.
    As mentioned
    Name Recently Created Opportunities
    Description Opportunities sorted by Created Date
    List Accessibility Public (everyone can use it)
    Search In All records I can see
    Created: Date External Descending
    But I need to how many top(?) or range(?) Opportunities sorted by Created date descending order.
    Any information will helpful to me.
    Thanks & Regards,
    Santosh Nayak

    I believe recently created opportunities list shows all the opportunities in descending order.(created date).
    You should be able to create your own recently created list by adding additional filters.
