    Back up all data immediately as your boot drive may be failing.
    If you have more than one user account, these instructions must be carried out as an administrator.
    Triple-click anywhere in the line below on this page to select it:
    syslog -k Sender kernel -k Message CReq 'Channel t|GPU D|I/O|Previous Sh' | tail | open -ef
    Copy the selected text to the Clipboard (command-C).
    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).
    The command may take a noticeable amount of time to run. Wait for a new line ending in a dollar sign (“$”) to appear.
    A TextEdit window will open with the output of the command. If the command produced no output, the window will be empty. Post the contents of the TextEdit window (not the Terminal window), if any — the text, please, not a screenshot. The title of the window doesn't matter, and you don't need to post that.

  • How to clean the dust inside the screen of the iPod Touch?

    Hi everybody,
    lately some dust entered inside the screen of my iPod Touch.
    At first it looked like one or two pixels were gone bad, but it is just some annoying dust.
    The problem is that I cannot figure out any way to remove it.
    I tried a gentle blow from the connector hole but the result was worse.
    Any idea on how to clean the screen inside?
    I hope it is not necessary to go to an Apple Center and pay for the "cleaning service".
    Regards,
    Andrea

    It sounds safe to use
    'Falcon's® "Professional" Dust-Off® "XL" compressed-gas is the perfect product for removing dust from your color transparencies before making scans or copy slides; it's also great for removing dust from cameras, lenses, computers and other electronic equipment. Each 12 oz. disposable can comes with its own trigger value and a 4.75" nozzle extension (a red tube) that allows you to place precise bursts of compressed air just where you want it.'
    Check the directions on the back... also check the contents. Normally anything like that will inform you of contaminants harmful to delicate electrical devices.
    If its just compressed air make sure you keep the can well back from the source.. and unplug the G5 (take it somewhere you don't mind dust.. there no point doing this in situe, just for it to suck it back in again!)
    Also.. as mentioned.. keep the can upright (as the air is decompressed the can gets very cold)

  • I am thinking of buying a MacBook Air and am wondering how to get the content of my iPad into iTunes.

    I have iTunes on an old pc and am thinking of buying a MacBook Air. I am wondering how to get the content of my iPad on to the Mac as I know that sync only happens in one direction, from pc to device. I assume therefore that when I attach my pad to the new Mac it will sync to an empty iTunes and I will have lost all the content of my pad. I know I can restore purchases, but what about contacts, calendar, photos and music not purchased from apple. I have a fairly recent backup on a pen drive but it is a usb2 device and is formatted for a pc. Any advice would be appreciated.

    Do I copy my media library or from a backup.  I have a backup on my pc and on an external drive. This drive is usb2 and formatted for windows so I can't connect it to a MacBook Air to make the transfer.  Equally I don't think there is a way to connect the 2 computers via a cable ie usb2 one end and usb3 the other.  Will the computers talk to each other via wifi if I enable home share although I think this is only for music which still leaves contacts, mail etc.
    I am sorry to be such an ignoramus but any further help would be appreciated.

  • Help me...How to read the content if "Transfer-Encoding:chunked" is used?

    I am doing a project for internet control using Java,PHP and MySql.All sites should go through the proxy server only.If the HTTP header contains Content-Length,am getting the content length as below:
    public class HTTPResponseReader extends HTTPMessageReader
        String statusCode;
        public HTTPResponseReader(InputStream istream) throws IOException,                     NoSuchElementException
      BufferedInputStream distream = new BufferedInputStream(istream);
      retrieveHeader(distream);
      StringTokenizer st =  new StringTokenizer(new String(HTTPMessageReader.toArray(header)));
      versionProtocol = st.nextToken();
      statusCode = st.nextToken();
      String s;
      while (st.hasMoreTokens())
            s = st.nextToken();
            if (s.equals("Transfer-Encoding:"))
           transferEncoding = new String(st.nextToken());
         if (s.equals("Content-Length:"))
           contentLength = Integer.parseInt(st.nextToken());
         if (s.equals("Connection:"))
          connection = new String(st.nextToken());
          if (connection.equals("keep-alive")) mustCloseConnection = false;
       retrieveBody(distream);     
    }After getting the Content-Length,i used read method to read the content upto that content length.Then i concatenated the HTTP header and body and the requested site was opened.But some sites dont have Content-Length.Instead of that,Transfer-Encoding is used.I got the HTTP Response header as "Transfer-Encoding:chunked" for some sites.If this encoding is used how to get the length of the message body and how to read the content.
    Can anybody help me.
    Thanks in advance...

    Why don't you use HttpUrlConnection class to retrieve data from HTTP server? This class already supports chunked encoding...
    If you want to do anything by yourself then you need to read HTTP RFC and find all required information. Well in two words you may reject advanced encoding by specifying HTTP 1.0 in your request or download chunked answer manually. Read RFC anyway :)

    Hi Gazpan,
    Thanks for visiting Apple Support Communities.
    I recommend using the steps in this article to back up your iPhone if possible:
    iOS: Back up and restore your iOS device with iCloud or iTunes
    http://support.apple.com/kb/ht1766
    You may also find this advice helpful for your situation:
    What to do before selling or giving away your iPhone, iPad, or iPod touch
    http://support.apple.com/kb/ht5661
    If you no longer have your iOS device
    If you're using iCloud and Find My iPhone on the device, you can erase the device remotely and remove it from your account by signing in to icloud.com/find, selecting the device, and clicking Erase. When the device has been erased, click Remove from Account.
    If you're unable to complete either of the above steps, you should change your Apple ID password. Changing your password won't remove any personal information that is cached on the device, but it will make sure that the new owner can't delete your information from iCloud.
    Cheers,
