  • I have a digital voice recorder with a 3.5mm mic and headphone jack and want to transfer some recorded lecture to my mac book pro.  The mac book does not have 3.5mm  jacks.  Does anyone know if a jack to USB converter would work?

    I have a digital voice recorder with a 3.5mm microphone and headphone jack and want to transfer some recorded lectures to my mac book pro.  The mac book does not have 3.5mm  jacks.  Does anyone know if a jack to USB converter would work?

    Is there a pattern to the time of day or other detail that may be
    traced back to a OS X system cause of this odd phenomenon?
    Are there any copies of system files on any of the attached USB
    external drives? Any libraries, such as iTunes, iPhoto, etc?
    Once the drives are indexed by Spotlight, are their permissions
    ignored by the OS X? Content, if neutral, should not affect the
    wake or sleep cycle; especially if they're ignored by the OS X.
    Could there be a bad cable or other component? If so that would
    be a difficult process of elimination to detect it. Usually replacing
    most suspect components in the USB stream (external to Macs)
    is a rote way to mechanically test that idea; & not 100% sure.
    Does the equipment all have a good ground to the utility or house
    electrical field? An intermittent ground may affect more than sleep.
    Hard to say at this point. Maybe a late-night talk radio guru on
    remote viewing could peer into your situation and sleuth it out?
    Sorry to have run out of ideas, but the process must be electrical
    & mechanical to some extent. - Or perhaps odd software inspired.
    Do you have any phone-home spyware items inside, just jumping
    at the chance to spill your information? Little Snitch may help.
    PS: Perhaps the computer needs to go into Apple & have a genius
    or product specialist at AASP test the unit thoroughly... BlueTooth?

  • My mac pro does not start up because then hard disk is formatted

    My mac pro does not start up because then hard disk is formatted, How can install the operating system.
    regards,
    Tassew

    Did you erase the hard drive yourself? If not, what exactly are you seeing, and what happened immediately prior to you starting to see it?
    Your profile indicates that you are/were running Lion (Mac OS X 10.7.4) on a retina MacBook Pro, so you should be able to hold down command-R at startup to enter recovery mode, and you can reinstall the system from there. But whether or not you need to do something else first depends on your answers to the questions above.

  • My old version mac book airdoes not start up so i tried to reinstall lion but it says its locked. how do i unloke it with out being able to start up the system.

    my old version mac book air does not start up so i tried to reinstall lion but it says its locked. how do i unlock it with out being able to start up the system.

    Could be. The "lock" isn't actually looking for a password.
    WARNING: This will completely erase the ENTIRE hard drive.
    What you would need to do is boot to recovery > disk utility > select the MAIN drive on the left side > partition > change partition layout from CURRENT to 1 PARTITION > ensure on the right side it says Format : Mac OSX Extended (Journaled) then push APPLY.
    Then if it will allow us, close the windows until you see the 4 options popup again and select "Reinstall Mac OS X" select the Mac HD and you should be good to go!

  • My Mac Pro does not start up

    I have a big problem with my MacPro which I bought just 3 months ago. A month ago it started to act up: sometimes it was slow and sometimes it's fine. When I type it's so slow and letters take time to show when typing. Now, it does not boot up or does not start. When I turn it on, it shows just the apple sign but it does not boot up! I need help as I am now out of the US.

    The best option is to take advantage of your warrantee and take it to an Apple repair facility.
    In the interim, look at this Apple support article and start there:

  • I have forgotten my password to get into my mac bokok pro. I have used my iPad to reset the password but my Mac book does not recognise the reset password.

    I have reset my password using my iPad. Why does my Mac book not recognise it to allow me to log in to it?

    What password did you change and what password is your Mac requesting.
    Without details all you will get is guesses.

    Hi Leon, and a warm welcome to the forums!
    Really tough to tell if you don't know what you deleted... is it still there in Applications?
    You may have to Custom Install it...

  • My mac book will not start at all

    Suddenly my mac book pro will not turn off.  first it started with the computer cutting off rather than going to sleeep then it started cutting off while I was using it.  I became worried that there was a problem and went to back up the hard drive on an external hard drive but suddenly the computer would not start at all.  before that happened i would get the gray screen with the dial and a bar underneath.  Help!

    See if these support articles help:

  • My Mac Book Does not shut down

    I got a top of the line MacBook in March 2011, paid some $3000. It has had a problem from the beginning and unfortunately the dealer convinced me at the time it was a random happening so i did not return it immediately. But it is really intolerable.
    When i try to turn it off, if i have used any programs, it goes to the blue screen but then the circle thing can be going forever and it never completely turns off and it heats up, even if i have quit all programs and nothing but the finder is running. I have to force shut off by pressing five buttons at the same time, including on/off button. It is irritating. At first i thought it was just an inconvenience at shut down, but increasingly the fan is working full time and so loudly all the time and when it does this i know it will not shut down. Shutting applications does not fix it. I have to turn it off, and go through the routine of forcing shut down. When using several applications i think it is slow for a macbook and apps go into loops of non-responding. For a mac with 8GB of memory, an i7 processor, it is not good enough. I am increasingly thinking that all the problems are linked. After 15 months of denial i have had enough of it.
    I have used macs since the 1990s and i am more than fed up with the number of lemons i have had from Apple. I just did not want to believe that this is another one. Just not good enough. SInce 2011 i have bought 8 ipods for presents, an ipad and this macbook. Lemons made me go away from macs but i came back.
    Anyone having similar problems?

    Just as an experiment, try resetting the SMC (http://support.apple.com/kb/HT3964).
    If that doesn't work, maybe someone else can come up with something. Did you buy AppleCare? I would have insisted on a fix during the first year of warranty, but if you bought AppleCare, you can always make an appointment at a Genius Bar and take it in (even if you don't have AppleCare, take it in - they won't charge you to diagnose the problem - just to fix it).

  • Mac mini does not start up after password is given

    Our mac mini is strating up, but when entering the right password there's coming a blue screen and you return to the login where you have to enter your password. Whe are sure we are typing the right password but the mini is not starting up and every time returns to the login user screen.
    OSX 10.4 and not a intel mini.
    Can anyone please help us.

    Hello, first try this...
    "Try Disk Utility
    1. Insert the Mac OS X10.4 Install disc, then restart the computer while holding the C key.
    2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu at top of the screen. (In Mac OS X 10.4 or later, you must select your language first.)
    *Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.*
    3. Click the First Aid tab.
    4. Select your Mac OS X volume.
    5. Click Repair Disk, (not Repair Permissions). Disk Utility checks and repairs the disk."
    http://docs.info.apple.com/article.html?artnum=106214
    Then try a Safe Boot, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, reboot when it completes.
    (Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive & clear caches.)
    If perchance you can't find your install Disc, at least try it from the Safe Boot part onward.

  • Mac Book Does Not See XP as Option On Startup with 'Option' Key

    After successful install of XP Pro, my Mac Book only shows the Mac HD on startup when I hold down the 'Option' key. Per instructions, this procedure is suppose to show both the Mac & Windows HDs and allow a choice at startup. Ant ideas how to fix?

    Hatter:
    I now have a premise for this problem. I used an XP install disc that I received with a Compaq laptop that I purchased last year. HP/Compaq often write their own information to the boot section upon install of the operating system. If this happened when I installed XP from the Compaq disc then this HP/Compaq boot information may be interfering with the XP boot being seen at startup when the option key is pressed.
    To prove this premise I need to know if you installed XP from a disc provide by an OEM under their brand such as HP. If so then we can conclude that the premise stated above is correct and that the solution would be to install a clean version of XP from MS.
    Can you help?

  • Mac book does not discover itouch in bluetooth

    My Macbook does not "discover" my Itouch when I sync with Bluetooth.  Both units are up to date and "discoverable."
    Thanks in advamce.

    The iPod does not contain the BT profiles necessary to pair with a computer.  The iPod can pair with headphones, speakers, keyboards (newer iPods), and some other iDevices via apps for some file transfer but mainly for game playing.  See the following:
