my mac book pro has frozen during installation of OS X Yosemite.  What should I do?

Wait it out for couple of hours.

  • I downloaded lion now my mac book pro has frozen can't get into my mac book, why?

    why can't I get into my mac book pro now thatI have installed Lion, just have a screen with my name in the middle with a nice picture of an eagle. I have had no trouble with my desktop, it loaded fine, don<><.

    Hi Donald.
    Okay, your problem is most probably due to automatic graphics switching. Since you can't login, the only way I see is by starting Lion in safe mode. You will be able to login. Then disable Automatic Graphics Switching in the Energy / Power settings of System Preferences. The exact name of the setting may differ depending on your MacBook and hardware.
    Regards.

    Five ways to eject a stuck CD or DVD from the optical drive
    Ejecting the stuck disc can usually be done in one of the following ways:
    1. Restart the computer and after the chime press and hold down the left mouse button until the disc ejects.
    2. Press the Eject button on your keyboard.
    3. Click on the Eject button in the menubar.
    4. Press COMMAND-E.
    5. If none of the above work try this: Open the Terminal application in your Utilities folder. At the prompt enter or paste the following:
         /usr/bin/drutil eject
    If this fails then try this:
    Boot the computer into Single-user Mode. At the prompt enter the same command as used above. To restart the computer enter "reboot" at the prompt without quotes.

  • I think my mac book pro has a virus - is that possible and what can I do?

    I think my mac book pro has a virus.  Is that possible and what can I do?
    I opened an attachment on an email claiming to be an order confirmation from Amazon.  I now have several copies of it on my desktop and can't delete them.

    It is highly likely that this attachment is malware. It's also highly likely that it is Windows malware. So you're probably not infected with anything. What is the exact name of the attachment you opened? Please be sure to include whatever extension the filename has (such as .exe, .pdf, .doc, etc).
    What happens when you try deleting the attachment files from your desktop? Is there an error message of some kind? If so, what is the exact error message you're seeing? (Please don't try to paraphrase it... tell us the precise wording of the message.)

    Repair the Hard Drive and Permissions
    Boot from your Snow Leopard Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list.  In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive.  If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
    If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
    The main difference if you are using Lion or Mountain Lion is that you must first boot from the Recovery HD. Simply boot from the Recovery HD to perform the above.
    Reinstall Snow Leopard Without Erasing The drive

    2. Reinstall Snow Leopard
    If the drive is OK then quit DU and return to the installer.  Proceed with reinstalling OS X.  Note that the Snow Leopard installer will not erase your drive or disturb your files.  After installing a fresh copy of OS X the installer will move your Home folder, third-party applications, support items, and network preferences into the newly installed system.
    Download and install Mac OS X 10.6.8 Update Combo v1.1.
    Reinstalling Lion/Mountain Lion Without Erasing The Drive
    Boot to the Recovery HD: Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
    Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the main menu. Repair the Hard Drive and Permissions as follows.
    When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list.  In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive.  If it does not say "Verified" then the hard drive is failing or failed.

If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu.
    Reinstall Lion/Mountain Lion: Select Reinstall Lion/Mountain Lion and click on the Continue button.
    Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.

  • My Mac Book Pro has slowed to less than a crawl (possibly from a worm or virus).  How do I make sure it's running at peak efficiency before I complain to comcast

    My Mac Book Pro has slowed to less than a crawl (possibly from a worm or virus).  How do I make sure it's running at peak efficiency before I complain to comcast

    Please answer as many of the following questions as you can. You may already have answered some of them; in that case, there's no need to repeat the answers.
    Restart the router and the broadband device, if they're separate. Any change?
    Run Software Update and install all available updates for OS X or the computer's firmware. Any change?
    If possible, connect to the router with an Ethernet cable and turn off Wi-Fi. Any difference?
    Are any other devices on the network, and if so, are they the same?
    If you can connect to more than one network, are they all the same?
    Are all network applications affected, or only some? If only some, which ones?
    Is networking always the same, or is the problem intermittent?
    Disconnect all other devices from the network. Any change?
    If you're running a MacBook with the lid closed, open the lid. Any difference?
    Start up in safe mode and test. Any difference?
    Start up in Recovery mode. From the OS X Utilities screen, select Get Help Online. A clean copy of Safari will launch. No plugins, such as Flash, will be available. Any difference?
    If possible, turn off Bluetooth and disconnect any USB 3 devices. Any difference?

  • I need to use an hp 6215 printer with my mac book pro.  the driver installation disk doesn't work.  where can i get a driver that will work?  i use OS X

    i need to use an hp 6215 printer with my mac book pro.  the driver installation disk doesn't work.  where can i get a driver that will work?

    With the Lion it is essentially unnecessary to resort to external driver disks. What's more, most of those disks are incompatible with the OS and should not be used. The system already carries a wide variety of printer description files (aka PPDs, which is what modern printing systems use as "drivers") for a lot of brands. And there was an HP printer update just two days ago.
    Just checked in mine and did indeed find that the HP OfficeJet 6200 Series, with or without Fax, is covered with the latest update.
    So just go thru the motions of creating a proper printer instance:
    Make sure the Mac "sees" the printer on the network.
    System Preferences / Print & Scan
    Click on the + button on the left column
    Select the appropriate type of printer, will use IP for the rest of this
    Select HP Jetdirect - Socket, default for HP network printers
    Type the IP address or look it up
    Name the printer for easy identification on the print dialog
    Let the Mac identify the printer model or manually choose the driver
    Click Add.
    Once the instance pops up in the list, can click on Options & Supplies for further config.

    You can use iCloud to lock it if you had that set up. Otherwise, the only thing to do is report the theft to the police. You may want to contact your homeowner's insurance to see if it would be worth filing a claim with them also.

  • Mac book pro has become very slow. How to analyze this and resolve this?

    My mac book pro has become very slow. How to analyze and resolve this?

    First, back up all data immediately, as your boot drive might be failing.
    There are a few other possible causes of generalized slow performance that you can rule out easily.
    Reset the System Management Controller.
    If you have many image or video files on the Desktop with preview icons, move them to another folder.
    If applicable, uncheck all boxes in the iCloud preference pane.
    Disconnect all non-essential wired peripherals and remove aftermarket expansion cards, if any.
    Check your keychains in Keychain Access for excessively duplicated items.
    Boot into Recovery mode, launch Disk Utility, and run Repair Disk.
    If you're booting from an aftermarket SSD, see whether there's a firmware update for it.
    Otherwise, take the steps below when you notice the problem.
    Step 1
    Launch the Activity Monitor 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 Activity Monitor in the icon grid.
    Select the CPU tab of the Activity Monitor window.
    Select All Processes from the menu in the toolbar, if not already selected.
    Click the heading of the % CPU column in the process table to sort the entries by CPU usage. You may have to click it twice to get the highest value at the top. What is it, and what is the process? Also post the values for % User, % System, and % Idle at the bottom of the window.
    Select the System Memory tab. What values are shown in the bottom part of the window for Page outs and Swap used?
    Next, select the Disk Activity tab. Post the approximate values shown for Reads in/sec and Writes out/sec (not Reads in and Writes out.)
    Step 2
    If you have more than one user account, you must be logged in as an administrator to carry out this step.
    Launch the Console application in the same way you launched Activity Monitor. Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left. If you don't see that menu, select
    View ▹ Show Log List
    from the menu bar.
    Select the 50 or so most recent entries in the log. Copy them to the Clipboard (command-C). Paste into a reply to this message (command-V). You're looking for entries at the end of the log, not at the beginning.
    When posting a log extract, be selective. Don't post more than is requested.
    Please do not indiscriminately dump thousands of lines from the log into this discussion.
    Important: Some personal information, such as your name, may appear in the log. Anonymize before posting. That should be easy to do if your extract is not too long.

  • Hello, I'm pretty sure my fan on my 2009 mac book pro has stopped running. Would this cause the computer to slow down and take for ever to boot up and show the color wheel every time I select an application ?

    Hello, I'm pretty sure my fan on my 2009 mac book pro has stopped running. Would this cause the computer to slow down and take for ever to boot up and show the color wheel every time I select an application ? how involved to replace fan ? cost ?
    thanks

    Not directly, but if the CPU overheats because of incompatible software, that would cause slowdowns. Do not allow the computer to run if the fan is not working unless you wish to fry your motherboard. Please make a Genius Appointment and take it in for service.

  • My mac book pro has a white screen and won't start up

    My Mac book pro has been running slow, so I thought I would shut down and reboot. It wouldn't reboot past a white screen and an apple logo. I have rebooted several times and after an hour or so it still won't go any further. Any suggestions?

    If you didn't have "Find My Mac" enabled under the iCloud System Preferences pane, there's likely no way to trace your machine over the Internet.
