Mac is making a double note ( sound) on its own?

My mac makes an intermittent double note sound on its own without any keys being pressed? Is there something open that needs closing or erasing?

Hello
I know this is an old thread - but did you ever find the solution to this.
My colleagues come into the office this morning and said my iMac was making a sound similar to a drill. The iMac was not hot or vibrating.
Worried as I am now sat in front of it and not wanting it to blow up!
Many thanks
Lewis

  • Why iPhone 5 not charge with its own charger but will with iPhone 4 charger

    why iPhone 5 not charge with its own charger but will with iPhone 4 charger. Thanks to the member who posted that fix.

    It sounds to me like the charger that came with the iPhone 5 is defective, or the cable is if you've been switching the cables when you switch the chargers.

  • JSP error page does not displayed on its own, includes in the original JSP

    Problem Description: - Exceptions in a Condition cause pages to fail to render.
    The actual issue is, the JSP error page does not displayed on its own, included in the original JSP Page when exception occurs.
    Problem Cause: As per the JSP specification when jsp content reached the buffer size (default 8KB) the page being flushed (Part of condent displays). The default �autoFlush� value is true.
    When the page buffer value is default size (8KB), and if any exception occurs after flushing the part of the content, instead of redirecting into error page, the error page content included in the original page.
    If i specify autoFlush="false" and with default buffer size, at the runtime if the buffer size is reached, i am getting stackoverflow error.
    To solve the above problem we can make it autoFlush=�false� and buffer=�100KB�. But we can�t predict the actual size of the page.
    I found in one of the weblogic forum as no solution for this issue. Ref.
    http://support.bea.com/application?namespace=askbea&origin=ask_bea_answer.jsp&event=link.view_answer_page_clfydoc&answerpage=solution&page=wls/S-10309.htm
    Please provide me any solution to resolve the problem.

    Error-Page tags work best with an error.html pages. If you have an error.jsp page what I would do, and I have, is wrap my classes and jsp pages in a try catch block where you forward to the error jsp page and display anything you want. YOu can also do this with if else statements. I have used the tomcat error pages before but when I've implemented them I used java.lang.Exception as the error to catch not Throwable. I don't know if this would make a difference or have anything to do with your problem.

    Hello Pankaj,
    I recommend to post this query to the [BusinessObjects Enterprise Administration|BI Platform; forum.
    This forum is dedicated to topics related to administration and configuration of BusinessObjects Enterprise, BusinessObjects Edge, and Crystal Reports Server.
    It is monitored by qualified technicians and you will get a faster response there.
    Also, all BOE Administration queries remain in one place and thus can be easily searched in one place.
    Best regards,

  • Making Garageband songs not sound like Garageband songs

    Is there a trick to making GBand songs sound like 'normal' songs? When I play songs I've created in GBand on my car stereo, it sounds awful compared to 'real' music. I've played around with the Master Tracks, but nothing seems to work well. I want my music to envelope/surround me, not sound like I'm tinkering around with a cheap keyboard. Thanks.

    Well....
    This isn't what you want to hear, but GB is only as good as the person using it. I have some friends that are trained audio engineers and they can make GB sound as good as anything. I do a pretty good job too. LOL!
    What I would like to emphasize if you are looking for pro sounding recordings:
    -get decent monitors,
    -learn to use your microphones AND the space/room you are recording in,
    -read up on the art of mixing,
    -learn what a compressor does and familiarize yourself with them,
    -practice mixing other's songs (Nine Inch Nails has 2 of their songs as free GB downloads for mixing)
    -read and practice, read and practice, read and practice, read and practice, read and practice, read and practice, read and practice, read and practice, read and practice, read and practice, read and practice, read and practice, read and practice, read and practice, read and practice, read and practice, read and practice, read and practice, read and practice, read and practice,
    and that about covers it. Garageband is just a tool. You have to make it work.
    Good luck and welcome to the forum! If you have any questions, feel free to ask. Lots of smart people here.

  • Mac Pro 4,1 kernel panic - restarts on its own

    I have a Mac Pro 4,1 that will not finish the start up process   It kernel panics at the end of the process. It will then do a restart on its own and kernel panics again.
    What's the best way to figure out what's wrong with it?  HDs? Processor ? Or the RAM? I have not changed anything for a long time.
    Thanks

    Please read this whole message before doing anything.
    This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
    The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, or by a peripheral device. 
    Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode and log in to the account with the problem. Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Ask for further instructions.
    Safe mode is much slower to boot and run than normal, and some things won’t work at all, including Wi-Fi on certain iMacs. The next normal boot may also be somewhat slow.
    The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin. Test while in safe mode. Same problem? After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of the test.

  • MacBook Pro 15" Late 2008 will not sleep on its own

    My MacBook Pro will sleep just fine if I close the lid or select sleep from the Apple menu. It won't, however, ever fall asleep on its own. I've tried resetting the SMC to no avail. Any suggestions as to what I should look for?

    Certain settings, e.g. printer sharing, can prevent timed sleep. If it's a brand new Mac and you migrated a fair amount of data from a previous computer, Spotlight may still be indexing. There are other possibilities as well. See this kbase article:

  • One note starts on its own when I use Remote Desktop connection

    Whenever I use RDC to connect to my home server, One note start and pops up totally on its own on my local computer.
    Can anyone explain why, and more importantly how I can stop this behaviour?

    After hours of reading through forums and posts similar to this one, and knowing the proposed work-arounds were not going to be accepted by my client that was having the issue, I came to the conclusion that it had to be a print driver or the software that
    gets installed along with the print driver on the server that was causing my issue.
    I started searching and came across some Epson software that was installed on the remote desktop server when I was trying to get a scale house ticket printer to work as a network printer. The printer was not installed on the server but the software remained
    in the add and remove programs list.
    I removed the three Epson entries in the add and remove programs list and the problem stopped.
    I don't know if this was mentioned above but the behavior I observed was that the print job was going to multiple printers, not just OneNote. I my case if I removed the OneNote pritner I would then get prompted by the Microsoft XPS Document Writer for a
    file location to save to.
    I could open the print queue for each of the printers that were getting redirected on my local machine, I would then log in to the remote desktop server that I was having the issue on. I could see the "remote desktop redirected printer doc" get
    sent to each printer. If the printer was online it would flash for only a moment and the printer would ignore the job as if nothing had been sent to it. If the printer was offline the job would stay in the queue.
    I think this was mentioned above so I will reiterate, don't approach the issue like it is a problem just with OneNote or with a particular driver from a particular manufacturer. We know at the very least that the problem can be caused by Samsung driver/printer
    software and by Epson driver/printer software so it stands to reason that there can be other drivers/printer software packages that can cause the same problems.
    I hope this helps! 

  • My mac is making a very loud sound, it sounds like a broken fan! What does it mean?

    What does this sound mean? Do I need a new part or what?

    late 08 MBP are infamously noisy.

    my other guess is it's dirty.
    but it could be more serious like your hard drive, not a fan. 

  • Ios 7.4  nightmares. When idle and charging my screens move on their own, types jibberish on its own and sends the jibberish as a text message to random callers, changes sounds on its own.  And that's not all!!!

    The ios7.04 download for my iphone 4s has tuned the phone into a nightmare. Battery charging time is 3x what it used to be, battery drains after 4 hours whether I talking or phone is idle. I can no longer hear the phone when it rings. Here is the dealbreaker:When idle, untouched and charging the screens move on their own, type jibberish on their own and send the jibberish via text to a random selection of my contacts. The phone is charging now and I am watching the screen move to the alarm stopwatch screen. It  From there is has moved to the Sounds screen and has changed my ring tone twice. (It plays the tones as well.). My hands are not on the phone at the time and the homescreen is visible when charging begins. I have turned off so many components of the phone that there is simply no longer any reason to walk around with what has become a functionless burden. The most obvious solution is to say goodbye to Apple and go back to the brand I was using before. Thought I's give this forum one last shot. For the life of me I can not understand why so many of us have so many complaints about our devices yet no one takes the path of least resistance...which is to simply switch to a brand that is reliable. I never had any problems with a cell phone until I switched to Apple.

    Thank you. I called my carrier and told them that the i704 os made my phone unusable and that the support in the forums is populated by children like yourself who make nasty comments and provide no support, I was released from my contract. Free at last from rotten Apple and shmucks like you.
