I have tried installing a disc to try and reinstall the operating system.
Disconnect all peripherals from your computer. Boot from your install disc & run Repair Disk from the utility menu. To use the Install Mac OS X disc, insert the disc, and restart your computer while holding down the C key as it starts up.
Select your language.
Once on the desktop, select Utility in the menu bar.
Select Disk Utility.
Select the disk or volume in the list of disks and volumes, and then click First Aid.
Click Repair Disk.
Restart your computer when done.
Repair permissions after you reach the desktop-http://docs.info.apple.com/article.html?artnum=25751 and restart your computer.
If you did manage to reach the desktop after doing any of the above
my battery was dying after a few minutes so I was trying to kill the battery and recharge it to see if I couldn't get it back to a full charge.

    I have a late 2011 model MacBook Pro running Mountain Lion.  I love the AirPlay mirroring feature with Apple TV...BUT, how do I mirror with TVs that don't have Apple TV?  I used to run a cable from my mini display port to the HDMI input of a TV.  This feature seems to be lost in the Mountain Lion upgrade.  Did Apple feel that once Mountain Lion came out that EVERYONE would have Apple TV?  There are no settings in System Preferences/Display like there used to be...only for AirPlay Mirroring.

    Running a cable to the HDMI port is still supported. (and still works on mine).
    If the Arrangement tab in System Preferences > Displays isn't present then it doesn't recognize the physical connection.  Double check all cables.  If that doesn't work try a PRAM reset:

    Kappy's Personal Suggestions About OS X Maintenance
    For disk repairs use Disk Utility.  For situations DU cannot handle the best third-party utility is: Disk Warrior;  DW only fixes problems with the disk directory, but most disk problems are caused by directory corruption. Drive Genius provides additional tools not found in Disk Warrior for defragmentation of older drives, disk repair, disk scans, formatting, partitioning, disk copy, and benchmarking. 
    Four outstanding sources of information on Mac maintenance are:
    1. OS X Maintenance - MacAttorney.
    2. Mac maintenance Quick Assist
    3. Maintaining Mac OS X
    4. Mac Maintenance Guide
    Periodic Maintenance
    OS X performs certain maintenance functions that are scheduled to occur on a daily, weekly, or monthly period. The maintenance scripts run in the early AM only if the computer is turned on 24/7 (no sleep.) See Mac OS X- About background maintenance tasks. If you are running Leopard or later these tasks are run automatically, so there is no need to use any third-party software to force running these tasks.
    If you are using a pre-Leopard version of OS X, then an excellent solution is to download and install a shareware utility such as Macaroni, JAW PseudoAnacron, or Anacron that will automate the maintenance activity regardless of whether the computer is turned off or asleep.  Dependence upon third-party utilities to run the periodic maintenance scripts was significantly reduced after Tiger.  (These utilities have limited or no functionality with Snow Leopard, Lion, or Mountain Lion and should not be installed.)
    Defragmentation
    OS X automatically defragments files less than 20 MBs in size, so unless you have a disk full of very large files there's little need for defragmenting the hard drive except when trying to install Boot Camp on a fragmented drive. But you don't need to buy third-party software. All you need is a spare external hard drive and Carbon Copy Cloner.
    Cheap and Easy Defragmentation
    You will have to backup your OS X partition to an external drive, boot from the external drive, use Disk Utility to repartition and reformat your hard drive back to a single volume, then restore your backup to the internal hard drive. You will use Carbon Copy Cloner to create the backup and to restore it.
      1. Get an empty external hard drive and clone your internal drive to the
           external one.
      2. Boot from the external hard drive.
      3. Erase the internal hard drive.
      4. Restore the external clone to the internal hard drive.
    Clone the internal drive to the external drive
      1. Open Carbon Copy Cloner.
      2. Select the Source volume from the left side dropdown menu.
      3. Select the Destination volume from the left side dropdown menu.
      4. Be sure the Block Copy button is not depressed or is ghosted.
      5. Click on the Clone button.
    Destination means the external backup drive. Source means the internal startup drive.
    Restart the computer and after the chime press and hold down the OPTION key until the boot manager appears.  Select the icon for the external drive and click on the upward pointing arrow button.
    After startup do the following:
    Erase internal hard drive
      1. Open Disk Utility in your Utilities folder.
      2. After DU loads select your internal hard drive (this is the entry with the
           mfgr.'s ID and size) from the left side list. Note the SMART status of the
           drive in DU's status area.  If it does not say "Verified" then the drive is
           failing or has failed and will need replacing.  SMART info will not be
           reported  on external drives. Otherwise, click on the Partition tab in the
           DU main window.
      3. Under the Volume Scheme heading set the number of partitions from the
           drop down menu to one. Set the format type to Mac OS Extended
           (Journaled.) Click on the Options button, set the partition scheme to
           GUID then click on the OK button. Click on the Partition button and wait
           until the process has completed.
    Restore the clone to the internal hard drive
      1. Open Carbon Copy Cloner.
      2. Select the Source volume from the left side dropdown menu.
      3. Select the Destination volume from the left side dropdown menu.
      4. Be sure the Block Copy button is not selected or is ghosted.
      5. Click on the Clone button.
    Destination means the internal hard drive. Source means the external startup drive.
    Note that the Source and Destination drives are swapped for this last procedure.
    Malware Protection
    As for malware protection there are few if any such animals affecting OS X. Starting with Lion Apple has included built-in malware protection that is automatically updated as necessary.
    Helpful Links Regarding Malware Protection:
    1. Mac Malware Guide.
    2. Detecting and avoiding malware and spyware
    3. Macintosh Virus Guide
    For general anti-virus protection I recommend only using ClamXav, but it is not necessary if you are keeping your computer's operating system software up to date. You should avoid any other third-party software advertised as providing anti-malware/virus protection. They are not required and could cause the performance of your computer to drop.
    Cache Clearing
    I recommend downloading a utility such as TinkerTool System, OnyX 2.4.3, or Cocktail 5.1.1 that you can use for periodic maintenance such as removing old log files and archives, clearing caches, etc. Corrupted cache files can cause slowness, kernel panics, and other issues. Although this is not a frequent nor a recurring problem, when it does happen there are tools such as those above to fix the problem.
    For emergency cleaning install the freeware utility Applejack.  If you cannot start up in OS X, you may be able to start in single-user mode from which you can run Applejack to do a whole set of repair and maintenance routines from the command line.  Note that AppleJack 1.5 is required for Leopard. AppleJack 1.6 is compatible with Snow Leopard. (AppleJack works with Snow Leopard or earlier.)
    Installing System Updates or Upgrades
    When you install any new system software or updates be sure to repair the hard drive and permissions beforehand. I also recommend booting into safe mode before doing system software updates.
    Backup and Restore
    Having a backup and restore strategy is one of the most important things you can do to maintain your computer. Get an external Firewire drive at least equal in size to the internal hard drive and make (and maintain) a bootable clone/backup. You can make a bootable clone using the Restore option of Disk Utility. You can also make and maintain clones with good backup software. My personal recommendations are (order is not significant):
      1. Carbon Copy Cloner.
      2. Deja Vu
      3. SuperDuper!
      4. Synk Pro
      5. Tri-Backup
    Visit The XLab FAQs and read the FAQs on maintenance and backup and restore.
    Always have a current backup before performing any system updates or upgrades.
    Be sure you have an adequate amount of RAM installed for the number of applications you run concurrently. Be sure you leave a minimum of 10% of the hard drive's capacity or 20 GBs, whichever is greater, as free space. Avoid installing utilities that rely on Haxies, SIMBL, or that alter the OS appearance, add features you will rarely if ever need, etc. The more extras you install the greater the probability of having problems. If you install software be sure you know how to uninstall it. Avoid installing multiple new software at the same time. Install one at a time and use it for a while to be sure it's compatible.

  • Is the Dell 3115CN compatible with a Macbook Pro running Mountain Lion? If so, how can I install the drivers and install the printer on my mac?

    I hace a Macbook Pro running Mountain Lion OS.... I need to print from time to time but don't have a new printer to go with my new macbook. Would a 3115CN work with it or no? If so, how can I set it up? Setting up a printer on a mac is a bit different from doing so on a windows machine and I am new to the macworld.
    All help would be greatly appreciated.

    Yes. I'm running this printer from 10.6 through 10.9 and it's worked fine with all versions. Dell released updated drivers a while ago that make it much easier to administer this printer.

  • MacBook Pro running mountain lion restarts with Ethernet connected

    Hi all,
    My MacBook Pro (early 2012 15") running Mountain Lion (10.8.1) seems to always restart whenever I connect it to an Ethernet. The wireless works fine and there are no problems. The Ethernet connects then about a minute later my MacBook just restarts no matter what I am doing. I have gotten a new Ethernet cable but the same issue keeps happening. I haven't been able to try another Ethernet port as of yet, I am at school so mine might not work correctly however the Ethernet works fine for my friends PCs.
    Does anyone have any ideas that could help me? I would really like to use Ethernet because the wireless here tends to be slow.
    Thank you!

    I realize no one has responded to this but I am still having the issue even after a month. I also now have a panic report if that helps at all.

  • Late 2011 MacBook Pro running Mountain Lion - Have two external displays (one MiniDisplay, one VGA-USB), how do I rotate just the one screen?

    The primary, horizontal monitor is connected by the VGA-MiniDisplay adapter, and the secondary monitor (vertical) is connected with a VGA-USB adapter. They both connect fine, but I only have the option to rotate both at once. That is, the main 'System Preferences' window that shows up on the primary monitor has the option to rotate, but only there -- when I rotate that screen it rotates both.
    Also, I'm not going to be using the actual MacBook screen. Any ideas as to how I can get this to work? Thanks!

    The Apple TB displays I've seen come with two TB connectors. You can cascade them in daisy-chain fashion.
    However, you are limited to how much information the GPU can produce and store. I've been told by the local apple shop (not an official Apple Store) geeks that if you cascade two of the big displays onto one of the Macs (big models), both will fire up, but the Mac's internal display will be disabled. Apparently 1GB of VRAM isn't enough for so many framebuffers.

  • Does the HDMI cable carry both video and audio? U

    Does the HDMI cable carry both video and audio?
    If so what is the purpose of the separate optical audio connection?
    Just a little confusion setting the Apple TV Up with my AV receiver.
    TIA.

    You would use both HDMI and optical by connecting the former to a TV and the latter to a receiver that doesn't have an HDMI input so that you could play the audio through your stereo system.
    You can use the HDMI alone, typically directly to the TV or through an A/V receiver, as HDMI does carry both video and sound.
    For the year prior to the disastrous 4.4 updates a couple of weeks ago, you could use optical alone to add AirPlay music capabilities to your stereo system, so that you could stream music from iTunes and devices like the Touch and iPhone to your stereo. The 4.4 update broke that capability, requiring the use of HDMI for no reason. Lots and lots of people have been complaining about that bug, as it effectively bricks the Apple TV for anyone who bought it for this purpose but can't use the HDMI connection.

    Precisely why it's not an iPad, and why it doesn't cost very much.  An Apple rep would tell you how to connect an iPad to every computer.

    Hi,
    I purchased Huawei Dongle and trying to connect with my new MacBook Pro (OS- Mountain Lion) USB port 3.0 but unfortunately it does not support.
    When I plugged in my macbook the power is flowing in dongle due green light blinking twice in every 3 sec but no connection found or diver shown.
    Please let me know how I have to use it. I got some suggestion for USB hub 2.0 but It does not make any sense and driver installation.
    So please suggest proper direction to use it and provide link to install any driver.
    Thanks
    Tauheed Ahmad

    Yes Clinton I did same, but they were (Huawei customer support) surprised about this problem, They behave like they have no idea about USB 2.0 and  3.0 knowledge. They handsUp that reason I posted my problem in this forum.
    So is there any better solution to use any mediator between these USB version handling, Please let me know.
    Thanks

    Purchased a used macbook pro with Mountain Lion. My old Mac runs Snow Leopard is backed up to Time machine. How do I register the operating system to me and how do I use Time Machine to move my files to the new used computer?

    If you look at the User Tips tab, you will find a write up on just this subject:
    https://discussions.apple.com/docs/DOC-4053
    The subject of buying/selling a Mac is quite complicated.  Here is a guide to the steps involved. It is from the Seller's point of view, but easily read the other way too:
    SELLING A MAC A
    Internet Recovery, and Transferability of OS & iLife Apps
    Selling an Old Mac:
    • When selling an old Mac, the only OS that is legally transferable is the one that came preinstalled when the Mac was new. Selling a Mac with an upgraded OS isn't doing the new owner any favors. Attempting to do so will only result in headaches since the upgraded OS can't be registered by the new owner. If a clean install becomes necessary, they won't be able to do so and will be forced to install the original OS via Internet Recovery. Best to simply erase the drive and revert back to the original OS prior to selling any Mac.
    • Additionally, upgrading the OS on a Mac you intend to sell means that you are leaving personally identifiable information on the Mac since the only way to upgrade the OS involves using your own AppleID to download the upgrade from the App Store. So there will be traces of your info and user account left behind. Again, best to erase the drive and revert to the original OS via Internet Recovery.
    Internet Recovery:
    • In the event that the OS has been upgraded to a newer version (i.e. Lion to Mountain Lion), Internet Recovery will offer the version of the OS that originally came with the Mac. So while booting to the Recovery Disk will show Mountain Lion as available for reinstall since that is the current version running, Internet Recovery, on the other hand, will only show Lion available since that was the OS shipped with that particular Mac.
    • Though the Mac came with a particular version of Mac OS X, it appears that, when Internet Recovery is invoked, the most recent update of that version may be applied. (i.e. if the Mac originally came with 10.7.3, Internet Recovery may install a more recent update like 10.7.5)
    iLife Apps:
    • When the App Store is launched for the first time it will report that the iLife apps are available for the user to Accept under the Purchases section. The user will be required to enter their AppleID during the Acceptance process. From that point on the iLife apps will be tied to the AppleID used to Accept them. The user will be allowed to download the apps to other Macs they own if they wish using the same AppleID used to Accept them.
    • Once Accepted on the new Mac, the iLife apps can not be transferred to any future owner when the Mac is sold. Attempting to use an AppleID after the apps have already been accepted using a different AppleID will result in the App Store reporting "These apps were already assigned to another Apple ID".
    • It appears, however, that the iLife Apps do not automatically go to the first owner of the Mac. It's quite possible that the original owner, either by choice or neglect, never Accepted the iLife apps in the App Store. As a result, a future owner of the Mac may be able to successfully Accept the apps and retain them for themselves using their own AppleID. Bottom Line: Whoever Accepts the iLife apps first gets to keep them.
    SELLING A MAC B
    Follow these instructions step by step to prepare a Mac for sale:
    Step One - Back up your data:
    A. If you have any Virtual PCs shut them down. They cannot be in their "fast saved" state. They must be shut down from inside Windows.
    B. Clone to an external drive using using Carbon Copy Cloner.
    1. Open Carbon Copy Cloner.
    2. Select the Source volume from the Select a source drop down menu on the left side.
    3. Select the Destination volume from the Select a destination drop down menu on the right
    side.
    4. Click on the Clone button. If you are prompted about creating a clone of the Recovery HD be
    sure to opt for that.
    Destination means a freshly erased external backup drive. Source means the internal
    startup drive. 
    Step Two - Prepare the machine for the new buyer:
    1. De-authorize the computer in iTunes! De-authorize both iTunes and Audible accounts.
    2, Remove any Open Firmware passwords or Firmware passwords.
    3. Turn the brightness full up and volume nearly so.
    4. Turn off File Vault, if enabled.
    5. Disable iCloud, if enabled: See.What to do with iCloud before selling your computer
    Step Three - Install a fresh OS:
    A. Snow Leopard and earlier versions of OS X
    1. Insert the original OS X install CD/DVD that came with your computer.
    2. Restart the computer while holding down the C key to boot from the CD/DVD.
    3. Select Disk Utility from the Utilities menu; repartition and reformat the internal hard drive.
    Optionally, click on the Security button and set the Zero Data option to one-pass.
    4. Install OS X.
    5. Upon completion DO NOT restart the computer.
    6. Shutdown the computer.
    B. Lion and Mountain Lion (if pre-installed on the computer at purchase*)
    Note: You will need an active Internet connection. I suggest using Ethernet if possible because
    it is three times faster than wireless.
    1. Restart the computer while holding down the COMMAND and R keys until the Mac OS X
    Utilities window appears.
    2. Select Disk Utility from the Mac OS X Utilities window and click on the Continue button. 
    3. After DU loads select your startup volume (usually Macintosh HD) from the left side list. Click
    on the Erase tab in the DU main window.
    4. Set the format type to Mac OS Extended (Journaled.) Optionally, click on the Security button
    and set the Zero Data option to one-pass.
    5. Click on the Erase button and wait until the process has completed.
    6. Quit DU and return to the Mac OS X Utilities window.
    7. Select Reinstall Lion/Mountain Lion and click on the Install button.
    8. Upon completion shutdown the computer.
    *If your computer came with Lion or Mountain Lion pre-installed then you are entitled to transfer your license once. If you purchased Lion or Mountain Lion from the App Store then you cannot transfer your license to another party. In the case of the latter you should install the original version of OS X that came with your computer. You need to repartition the hard drive as well as reformat it; this will assure that the Recovery HD partition is removed. See Step Three above. You may verify these requirements by reviewing your OS X Software License.

  • One of the users on my Mac book pro, running Mountain lion finds that no changes made in last session are there next time they log on

    One of the users on my Mac book pro running mountain lion finds that no changes made in last session are there next time they log on.
    For instance, the Macintosh HD icon, is always moved so that it is almost off the screen to top left hand side of the desktop.
    None of my changes to the sidebar in the finder are there.
    My changes to the dock have reverted.
    Despite unticking the box when logging out, even though i have quit all applications, iphoto and safari are always re-opened.
    iphoto always says the library needs to be upgraded... even though i did that the last time.
    I have tried deleting ALL the files in the "Saved application state" folder in the library folder, but that doesn't seem to make any difference.
    This is on a second admin user account.
    The main user account seems to be fine.
    This account used to be in the filevault on Lion, but is not now in Mountain Lion.
    Can anyone help?
    Thanks

    The same tragic thing happened to me, not even a full two days after I bought it. I immediately powered it off, wiped it as best I could, and put it in front of a fan. I tried valiantly to get the back off, but couldn't remove all the screws. I was basically inconsolable until I realized that no matter what, my credit card insurance would cover it, since it had been less than 90 days. Fast forward 48 hours, and it seemed to run just fine. Some of the keys and the track pad were sticky, and I figured since it was covered, I might as well get it fixed. My only concern at this point was had I voided the Apple Care. I brought it in, told them what happened, said what I needed to satisfy the credit card, and they said, "We'll just swap it out for you, no problem." I was thrilled, and the Genius said they appreciated my honesty, and it was easier for all parties to just do it this way. And my Apple Care was transferred to the new machine. This was my first Mac and, needless to say, I am now an Apple devotee.

  • HT1338 I updated my MacBook Pro with Mountain Lion and now it is starting slow and opening with some of the programs. How can I fix the problem?

    I updated my MacBook Pro with Mountain Lion and now it is slow in starting up and loads a number of probrams. How can I fix the problem?

    Have you tried starting in Safe Mode and see if the slowness still occurs?
    Restart holding the "shift" key.
    (Expect it to take longer to start this way because it runs a directory check first.)
    If this works look in System Preferences > Users & Groups > Login items and delete any third party login items (-), you can always add them back with the (+). Also look in /Library/Startup Items. Nothing is put in that folder by default, so anything in there is yours.
    Reboot normally and test.

    If your MacBook Pro had Snow Leopard on it at one time then sure. (Early 2011 or earlier)
    How to erase and install Snow Leopard 10.6
    Obviously choose the second partition to install into. It has to be OS X Extended journaled formatted in Disk Utility (BootCamp software makes it a MSDOS/FAT32 formatted partition if you used that to partition with)
    If it's a Early 2011 or Late 2011 that came with 10.7, it's possible, but it's not easy.
