I am have trouble with 2 new 21.5" iMacs losing wifi connection from my network. I have 4 other vintage iMacs that never lose connection. Please help.

This subject has been talked/written about a lot, after Lion was introduced. A solution from Apple has not yet been published, everybody is waiting.
Try for instance https://discussions.apple.com/thread/3734081?start=15&tstart=0, but there are more discussion groups with the same subject: frequently lost WiFi-connections in newer Macs running Lion or up.

    Sorry Butterbean, but I'm interested in the answer to your question myself.
    I've spent a few hours transfering my library from one computer to another and then find out that my ratings didn't transfer. Like you, I've spent many hours rating my 2000+ songs. I'm sure you have more, nevertheless, I want to find out how to get those ratings. They still show in my iTunes on my laptop but, when I go to the iTunes folder and display the details of at song, no rating is there. If you find out how to get them to display there in the iTunes folder, it seems that would be the key.
    Hope you get your answer soon.

  • I am having trouble with my bluetooth skipping while its playing music from my Itunes music...I thought that this was an antiquated problem with the new technology?

    I am having trouble with the music from my bluetooth "skipping" on my IPhone 5.  I thought that this was an antiquated problem with the new technology.  It's very frustrating to purchase all of this music and expect great sound and playability and get "skipping".  Any ideas on how to resolve this issue?

    Does the issue occur when listening to the media using the speaker or wired headphones?  If it does, the issue is with the media itself.
    If it does not, it's likely a bad connection or interference.

    I always have trouble with my mailbox. It is always asking for my passwords but everything has been verified. How can I get it to stop doing it and start working????

    There is only one thing that happens -- the Server does not respond.
    Your mac concludes that you must have entered the wrong password. That may happen once, but then other issues become more likely, and it keeps asking for a new password.
    Sometimes the Server is down for maintenance. Sometimes something is configured wrong. Some services do this on purpose to get you to use WebMail (pick up your Mail with your Browser) so they can show you some ads.

    Don't confuse the threads here with 'typical' experience.  Most of the stuff here is from brand new users, and those that have problems, and considering the 30 million pads in use, represent a very small sliver.
    If you are having repeated crashes it is really pretty basic.  You either have a physical problem with your pad, or you are using too much memory.
    The iOS system is supposed to monitor memory, and shut down previously used apps automatically to free up memory for what you are doing now.  That part of ios is not perfect, and if an app introduces an unexpected memory load, sometimes it gets over whelmed.  
    This happens, more often than not, when using safari with multiple windows open on graphic intense sites.  It can also happen with a memory intensive game, and residual apps in the background.
    Double  tap the home key and take a peek at the recently used list, and shut them down completely, and often the problem goes away.
    If the problem persists, you may have a software issue, and a trip to the genius bar may be in order.

    I am having trouble with new I-Phone 4 battery running down in 5 hrs.? Help.

    Do you have alot of apps running in background? Tap home key 2 times and there's a list across screen with icons you can deselect them by hold on one and they wiggle touch the minus button and it will deactivate them untill you use them again. Do you have the phone dim after so many seconds or minutes? Is the screen bright all time? Do you go on the Internet or watch video on phone?
    These things can affect the hrs of use.

  • I have trouble with my computer accepting an audio CD for I Tunes to download.  It remains in the computer for about 10- 15 seconds and then spits it out again.  Why???

    I have trouble with my computer accepting an audio CD that I want to download to ITunes.  It will remain in the computer for 10 - 15 seconds before ejecting it and not allowing me to download.  My ITunes is open.  Why does this happen or what am I doing wrong?  I have done this dozens of times before.  What makes this different and does it have anything to do with recent upgrades?

  • HT1338 I have a Leopard desktop 10.5.8 and I have trouble with MAIL. My draft folder does not work and my draft messages will not delete.        delete

    I have a Leopard desktop 10.5.8 and I have trouble with my Email Apple MAIL draft folder. First of all after I typed my draft and sent to draft, the folder would not open at a later date to send. In all I have 10 messages, mainly test which I cannot delete from my Draft folder.
    My draft system is now working but I cannot get rid of the  10 messages which sit in my INBOX and DRAFT folders.
    These messages appear in Application - Mail but they will not go.
    How do I delete, or is it best to use My Disc 1# and delete all my software and replace with the Disc in order to have a new MAIL program?
    Any advice would be welcome.

    HI,
    Not certain, but this can fix myriad Mail problems...
    Safe Boot from the HD, (holding Shift key down at bootup),  it will try to repair your Disk Directory while the spinning radian is happening, so let it go, run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, then move this folder & file to the Desktop.
    Move this Folder to the Desktop...
    /Users/YourUserName/Library/Caches/Mail/
    Move this file to the Desktop...
    /Users/YourUserName/Library/Mail/Envelope Index
    Reboot.
    If that doesn't do it and you can afford to redo all your Rules, try these & reboot...
    /Users/YourUserName/Library/Mail/MessageRules.plist
    /Users/YourUserName/Library/Mail/MessageRules.plist.backup
    Note, in 10.5 & up /Users/YourUserName/Library/Caches/Mail/ may or may not exist.

  • Permissions trouble with new MacBook Pro

    I had previously upgraded my MacBook Pro (original unibody model) to Mountain Lion with no apparent issues. I have two Users, both with Admin status and everything appeared to function as before.
    I just traded in my old MacBook Pro for a new current model Retina MacBook Pro, using Migration Assistant upon first startup to move everything over from the older machine. Most everything has been seamless - except for Permissions.
    I started seeing messages appear indicating I didn't have permission to open files, run apps, delete files, etc. Looking at Get Info, I found Sharing & Permissions was only set up for (if I recall correctly) Admin, Administrator and something called Wheel. I solved the permissions issue while logged in as the primary User by adding both Users to the Sharing & Permissions section of the Info screen for the entire hard drive, giving them Read & Write access, and selecting Apply to enclosed items... That seems to have solved the issue for the primary User.
    But then I tried working logged in as the secondary User. I started getting messages indicating I could not save a file I had just modified because I did not have permission, and that I should contact the Administrator. Well, that's me. So I tried the same thing that I did logged in as the primary User, but there was no change. I still can't save a modified file logged in as the secondary Admin User.
    I haven't found anything that addresses this - except to learn where the Wheel User originated. Can someone point me in the right direction to where I can learn how to gain full, unlimited access to my own computer - under bothe User accounts?
    Thank you.

    You corrupted the permissions of every file on the volume. Restore everything from the backup you made before doing that. Then do as follows.
    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 on this page 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.

  • Wifi trouble with new iMac

    I recently got a new iMac (27") and I am having an ongoing problem with wifi connection. It should be noted that other Apple devices -- iPad, iPhone, MacPro laptop, and Apple TV -- do not seem to have any trouble.  Nor did my old Mac Pro.  But the iMac connection keeps dropping. I have researched this issue in the Apple Support Forum and followed much of the advice, e.g. establishing a new connection identity, adjusting the DNS.  While these solutions seemed to work for a while it wasn't long before the problem returned. I have rebooted both the computer and the modem numerous times  (it is a DSL connection, BTW).  Those actions also seem to help for a while but sometimes they don't help at all.
    Since I transferred data from my old Mac Pro I have wondered if I have a preference or permissions issue. I know how to delete preferences when software acts up and that has sometimes been very helpful. But I don't know how to accomplish a similiar fix with the wifi.
    Software is up-to-date and I have not encountered any other problems with the iMac.
    Thanks.
    Alice

    The warranty entitles you to complimentary phone support for the first 90 days of ownership.
    If you bought the product in the U.S. directly from Apple (not from a reseller), you have 14 days from the date of delivery in which to exchange or return it for a refund. In other countries, the return policy may be different. If you bought from a reseller, its return policy applies.

    Copy all the content on your iPod back to your PC and into iTunes. Then go ahead and sync the iPod with your new library.

  • I got new iphone and when i connect it to my pc, it lost all my current data and replaced it with the backup on my computer, which is from april. so i have lost all my calendar information and schedule. does anyone know how i can reverse this?

    i got new iphone and when i connect it to my pc, it lost all my current data and replaced it with the backup on my computer, which is from april. so i have lost all my calendar information and schedule. does anyone know how i can reverse this and get my information back?

    Every backup replaces the old one, so, unless you included the backup folder in your computer backup routine, you can't get back your calendar info.
    The only time iTunes will not replace a backup is, when you use it to restore from, this one will stay in the backup list in iTunes.
