That doesn't sound good. It sounds like the power outage might have corrupted the partition for OS X. I would suggest booting from the Install DVD that came with your Mac while holding down the C key. Once you have selected the language start up Disk Utility from the pull down menu and repair the disk. Once you have done that then repair permissions also.

  • In trying to update my iPhone 3Gs from v. 3.13, it apparently downloaded the upgrade, but got stuck during the backup. It backed up for over an hour, and now the green bar in the Backup window is now colorless and is showing no movement.  Any suggestions?

  • MacBook slow wakeup, black screen, Mavericks, took to Genius bar, worked OK for about a week and now the same.

    MacBook slow wakeup, black screen, Mavericks, took to Genius bar, worked OK for about a week and now the same.
    Screen actually seems a very dark navy blue almost black. sometimes can see cursor in white
    Only happens sometimes

    If you can somehow document any processes you've put the MacBook
    through, which can cause it to repeat the symptoms you've seen, be
    sure to write down the sequence of events if your action and resulting
    issues can be make re-occur. Then you'd have a fair chance at some
    one looking deeper to find the real cause of this problem. {If you have
    a digital camera handy, you can take a picture of the screen if it should
    display some curious content other than a black screen, such as that
    seen in a kernel panic or other message. Otherwise, a working Mac
    can take its own screenshot.}
    The computer should be returned to the Apple Store genius bar for
    further evaluation & more in-depth diagnostic tests of long duration.
    Sometimes a test may not run any of the additional software, together
    or separately, that you may be accustomed to using. Perhaps the basic
    OS X and a few applications work just fine.
    If the issue is due to a conflict in software and not a hardware failure,
    the cause may be harder to discover. If you have a complete backup
    of the system and your files on an external drive, that may help if you
    need to reinstall it. However if there is a problem in that software set
    a new installation without conflicting software may be required in order
    to troubleshoot the machine.
    How old is the computer, how much RAM installed, how large a hard
    disk drive and what is the remaining unused capacity of that drive?
    (The HDD capacity will show 'other' so that may be unsubstantiated.)
    Are there any indications in Activity Monitor, or in the system log files
    from Console, to show crash logs or other effects from the Time/Date
    of these slow wakeup and black-screen intervals? There may be.
    Some of the system report may be helpful to those who know how to
    read the resulting mass of files. Perhaps one of the more advanced
    users who occasionally reply here will see your thread and offer a
    method of accessing the OS X via Terminal or single user mode,
    for troubleshooting purposes. Mine is an older OS X with less fuss.
    Good luck & happy computing!

    Someone else set up my iTunes account for me and I can't remember the Apple ID, the Password, or the name he put under it all. How do I get back into my iTunes account???? Or at least a number to call to get back???

    Go to Settings>Store>Apple ID, tap the ID shown, sign out, sign back in using the alternate ID.

  • HT1688 I just tried to install the latest software update for an iPhone 5, and now the phone is stuck in recovery mode.  Are there any options available to avoid going through with the recovery.  This seems really lame.

    No.
    You must restore.

    I changed out my old cell phone for a Motorola zoom and now the zoom has my old phone number associated with it's sim card. I just purchased a Samsung Android cell phone and would like to trade the sim from my new to cell to the zoom so I can have my old cell phone number back. The problem is the sim cards are different sizes. Is this something I can take to a store and get switched out?

    SRCLARK,
    Great question! You can go to the store and get a replacement SIM card at the store. Any corporate store will be more than happy to help replacing your card. http://bit.ly/3SdsA

  • I've had my Ipod for 3 years and now the battery only lasts an hour... do apple replace these?

    Ive had my Ipod nano for nearly 3 years and now the battery takes hours to charge and only lasts an hour at most..  do Apple replace batteries?

    Apple will do a like-for-like exchange of your iPod.  Be sure to have your music backed up prior to the exchange.

  • I have changed the name and password for my Time Capsule and now the Time Machine will not connect

    Mac Book Pro
    1TB Time Capsule.
    Yesterday I changed the name and password on my time capsule and also the name and password of the wifi network as I was having problems with the speed of the internet when using Safari on any of my devices (1 Macbook pro, 1 macbook air, 27" iMac, iPhone and iPad) all other internet services were working fine (email etc.) This seems to have solved the problem.
    However, since then, my time machine back ups will not reconnect and there is no option for me to reconnect to the existing back up for my macbook pro.
    When I enter the time machine preferences it shows as below that there are no back ups.
    Then, when I go to select a drive to use which should be the MacBook under the Backup disks the only option is for me to Remove Disk...
    So, my question is, how do I reconnect to an existing Time Machine back up for my MacBook pro as I really do not want to erase and start all over again.
    Warning - In my naiveté, I did click on the MacBook in 'Available Disks' but I got the impression that it was about to start a whole new back up and not work with the existing one.
    (And does anybody have an inkling as to why there was a problem with Safari on all my devices? I downloaded Google Chrome and that worked fine).

    Simply reset the Time Machine.
    See A4 here http://pondini.org/TM/Troubleshooting.html
    You can then mount the TC disk in finder after you reboot the computer.
    You should be able to reselect the TC disk and then it will say it is going to start a new backup.
    Ignore this.. when the TM actually loads the TC disk it will discover the existing backup and continue the backup.. but it will give no hint until it actually starts that it won't start a new backup. you just have to believe it won't.. and mostly it works..
    Please also install the widget A1 so you have some idea what TM is doing.

    The easy way is to Purchase an External Enclosure like the Startech USB 3.0 S2510BPU33 with UASP, its a Super Fast connection, SATA 3.1 @ 6 Gb/s.
    Just Pop your SSD inside the enclosure and use OS X Disk Utility to clone your existing HDD. This enclosure is So Fast you would not even have to open up your Mini to install the SSD, just Boot Externally you would Never Know the difference and your Warranty won't be affected by opening it up.

  • My wired Apple Magic Mouse is frozen and I am unable to move around on my Mini Mac.  I receive a window saying the computer cannot locate a wireless mouse.  How do I get my mouse to work again.

    My Magic Mouse is frozen.  How do I get it to work again?  Also I keep getting a window that says it cannot locate my wireless mouse.  I do not have a wireless mouse.

    Got confused between your header question about a wired mouse and the main question about a wireless mouse.  You said your magic mouse was frozen and added you do not have a wireless mouse.   Problem is ... the magic mouse is wireless.   The original mighty mouse was the corded version.
    The wired mouse is a regular problem.  After two to three years it tends to clog up. You can clean it (to a degree) as follows.
    Using an alcohol moistened, not wet, cotton bud, scratch at the mouse ball for a minute or so.   Then turn it upside down and on a clean piece of thick white paper or card on a firm surface, vigorously rub the mouse ball on the paper in a regular figure of eight.  Do this for a minute or so and occasionally tap the mouse on the paper.   This will help dislodge bits of fluff etc.   Then try again

  • How do i get back to Mac OS after installing Windows 7

    I just installed windows 7 on my macbook pro. i had OS Lion on my mac but I have no idea how to get back to it. If anyone knows how to go back and forth between the two operating systems PLEASE get back to me!

    Reboot/restart, and hold down the Option key on your keyboard before the screen goes black. Keep it held down, and you'll see a boot panel giving you the option of choosing Mac or Windows partitions.

  • Update pushed from Adobe for Acrobat X failed and now the "print to a PDF" option is missing. How do I get it back?

    Adobe pushed a security update to my computer and the update failed.  Now the "print to PDF" option is missing from all of my programs.  How do I get it back?
    Version X.1.12.

    Thanks.  That's exactly what I did, but from the Adobe help screen.  It did the trick, but I'm not very happy with Adobe for messing up my system.
    I appreciate your answering back.
