MacBook Pro running Leapord 10.5.5 cannot boot in normal mode

My 6 month old MacBook Pro (2.4 GHz Intel Core 2 Duo, 2GB DDR2 SDRAM) stopped being able to boot up in normal mode two days ago, after I happily used iMovie to import home movies from a HD digital camcorder, created small clips to upload to Yahoo Groups. The problem happened when I tried to boot the MBP up in the morning. Boot-up progresses to a grey screen with the Apple logo and a frozen progress indicator. The top 10% of the screen has just turned dark grey.
After browsing the forum on a PC, I successfully booted up in Safe Boot mode. Unfortunately, iMovie would not load in Safe mode and complains about not seeing the "Quartz Extreme" graphics card. I seem to be able to start VMware Fusion but is unable to start my Windows XP-Pro virtual machines because it "does not have the ACCESS RIGHTS" to it. I assume both symptoms are restrictions of SAFE BOOT mode.
I've tried the RESTART icon after I booted in Safe Mode to the Login screen. It took me to a grey screen with a large Power button icon and a black text box in the center that says "You need to restart your computer. Hold down the Power button for several seconds or press the RESTART button.....".
I have created another admin user from my original admin used ID (in Safe Mode) and is ready to start some of the debugging procedures, but I'm slightly lost about where to start (being a Mac user only since May, and spending much of that time working in a Windows VM). Could you please point me to a recommended orderly procedure to debug and restore my computer.
I have been using Time Machine to backup up my Home directory up to about 40 days ago, but has been away from home base for a while. Will be able to resume backup again in a couple of days. As long as I can access a USB drive through my USB ports in Safe Boot mode, I can copy my data changes for the last 40 days before I start doing anything dangerous with my MBP.

Why? This second hard-drive I want to format using FAT-32 is intended to be my offline storage that can be read by a Windows PC. I know that my Windows PC cannot read the HFS formatted drive I use for TM backup. I hope that once I move the bulk of my data offline, I can create a bootable disk image of my MBP with a manageable size.
I did used the default "HFS with Journaling" option when formatting my external USB drive for Time Machine backup. That's the only backup mechanism I use. I do not have another Mac (being a 'rebel' in a community of loyal PC users) accessible to use the backup data while I'm servicing my MBP. Since all my data is in industry standard data format (like rich text, jpg, html, mpg, flv) and Windows applications data I created in a Windows Virtual Machine on my Mac, my intention is to be able to view or use some of the data on a real PC while my Mac is down.
From reading Apple's own documentation on Time Machine (and please correct me if I'm wrong), with my TM backups, I should be able to restore my Mac by:
1) reformat my hard disk and re-install Mac OS X from the Install CD (Leapord 10.5.4)
2) update from Apple.com to Leapord 10.5.5
3) re-install all applications I've installed since I bought the computer
3) Start Time Machine, and select a certain option that would restore my whole system
Questions:
1) I've only use TM backups to restore individual files, never all files. Do I have the correct restore sequence? Has anyone done this successully? It looks like a mix bag when I look at the Time Machine discussions. Any tip would be appreciated.
2) I have moved directories around (before I realize the significance of the HOME directory) since I bought my Mac; in some cases returning the directory back to their original parent directory. Does this cause problem with TM restore?

  • MacBook Pro Retina 15" mid-2012 won't boot in clamshell mode with an external display attached

    I have a 15" MBPr mid-2012 running OS X 10.10.1. The system won't boot in clamshell mode (power is connected, lid shut) with an external display attached via an Apple Thunderbolt->DVI adapter. it boots fine if the lid is open. It isn't the adapter or the display since my 15" MBPr mid-2014 boots up just fine connected to the same adapter and monitor. And this system used to boot like this just fine some while ago (probably before it was upgraded to Yosemite). I've reset the NVRAM (twice) to no avail.
    Has anyone encounter this? Anyone have a solution? Should I try an SMC reset (always a bit nervous about that)? Might it be a driver issue in Yosemite?

    I have a macbook pro running snow leopard. Just recently I cannot view youtube videos and other online videos. I recently updated my flashplayer plugin and I believe that is the problem. Is the latest flashplayer plugin compatible with 10.6.8? If this is so, I need to find an older flash player plugin to reinstall. I do not want to upgrade from 10.6.8 at this time because I have 18 yrs. worth of financial records on Quicken that I have read will not work with Lion and I've read bad things about running music programs on Maverick.

    1)  Quicken 2007 for Intel (Snow Leopard, Lion, Mt. Lion and Mavericks) is a full featured app that can be downloaded from Intuit for $15 and will work with your data file if you are using Quicken 2005, 2006 or 2007 (if you version is earlier, let me know for more instructions on easy conversion):
    http://quicken.intuit.com/personal-finance-software/quicken-2007-osx-lion.jsp
    2) Partition your hard drive, or add an external hard drive and install Mavericks there and "dual-boot" to operate your music programs in Snow Leopard and experiment with them in Mavericks.
    DO NOT install Mavericks over Snow Leopard!

  • I suddenly cannot open facebook on my macbook pro running OSX 10.8.4. I am traveling in Vietnam, if that means anything. . .

    Hi. I've been traveling, using facbook on iphone and my macbook. Suddenly I cannot access Facebook. I prefer to use Safari as my broser, but I downloaded Mozilla tonight to just see if it was a browser issue. The problem carries over into Mozilla Firefox. Both say they can't find the server. However, I can access facebook through my iPhone.

    Thanks,

    Try enabling the Personal Hotspot on the iPhone and connecting the Mac to the Internet thru it. If Facebook works ok then, that would mean the ISP is either blocking or having connection problems whereas the phone carrier is not.
    Be mindful that carrier data charges can be outrageous so use this as a test first.

  • Unable to bind MacBook Pro (running 10.6 - Snow Leopard ) to Windows Server 2003 domain

    Hi there, I've been working on this problem for a few hours now (and a few hours last Thursday) and don't feel I'm getting anywhere, so I'm reaching out for help....
    My organisation has just purchased a new MacBook Pro, running Snow Leopard (OSX 10.6) and as a Technical Support Engineer I have been asked to configure it for an end user.
    I am currently trying to join it to our corporate domain, which is a Windows Server 2003 domain operating at the Windows Server 2003 Native domain functional level.
    The MacBook is configured to use DHCP, and has been assigned valid IP address, DNS servers etc by the DHCP server. It can resolve all names on our network, including the names of our domain controllers. When I use nslookup to resolve the name of the domain "my_domain.local" it returns a list of DC's on the domain, which would indicate to me that name resolution is working perfectly. It is using our primary DNS server, 'Ponus' to resolve these names - Ponus is also the Domain Controller in this site.
    To attempt to join the MacBook to the domain I have created a computer account for it on the domain, in the Computers container. I have gone into System/Library/Core Services and run the Directory Utility.
    In the directory Utility I have ticked Active Directory and clicked on it to edit. The 'Forest' field is greyed out and set to 'Automatic', in the 'Domain' field I have entered my_domain.local, which is the FQDN of my domain. I click Bind and when prompted enter my Domain Admin username and password (in the 'Create Computer Account in:' field it displays correctly as CN=Computers,DC=my_domain,DC=local.)
    When I click OK I get the message: Invalid domain. An invalid Domain and Forest combination was specified. You should enter a fully qualified DNS name for the domain and forest (e.g., ads.company.com).
    I have attempted writing the domain as my_domain.local, my_domain.local., MY_DOMAIN.LOCAL and MY_DOMAIN.LOCAL. but I get the same error each time. I have checked and rechecked DNS is resolving OK, and cannot see why it cannot find the Domain and Forest from the FQDN that I am entering. Even so I tried creating records in the hosts file on the MacBook to point to the main Domain Controller at this site (Ponus) but this didn't change anything.
    I have seen a few people report the same issue online but the responses tend to fizzle out before anyone gets to the bottom of it. I have seen some indication that people with an understore (_) in their domain name, or with a .local domain name may experience issues with joining Mac hosts, however these details are very vague and if true there must be a workaround.
    If anyone could help me with this I would greatly appreciate it, I'm running out of time to complete this work and have run out of things to try.
    I have an inkling that this is due to the Mac for some reason not reading the SRV records for the DCs and LDAP in DNS, or to do with the Mac looking only at one SRV record (ie. there is one for a new DC that we haven't deployed yet), not being able to reach this and giving up, but I'm clutching at straws really with my limited knowledge of the Macs process for joining the domain.
    Many many thanks,

    Hi there,
    A simple suggestion , please make sure both MacBook Pro clock and the server clock are the same meaning the hour/Min/ sec both should match. A least difference of 3 seconds is fine.
    I had faced this problem in many place and only solution was to match the time and it will bind immediatly.

  • MacBook Pro, iPad IV and iPhone 4S Cannot Connect to Server

    I have a MacBook Pro running Mountain Lion 10.8.5, and an iPad IV, both less than three months old. I also have a pair of iPhone 4s's.
    All of a sudden none of them can reliably connect to our AT&T Wireless home internet. There are particular websites we are blocked from viewing, notably any apple website, including apple.com, apple support, itunes, and App store, but also random ones like Wikipedia and others. We constantly get the "cannot connect to server" message. Yet other websites load right up with no problem.
    Many  websites are seriously snarled up, particularly Ebay, which is a critical one for me to have quick access to. Ebay screens are scrambled and out of order, act like purchases are being made when they're not, and photos don't show. All we get is little blue questionmarks.
    Multiple  PCs running on our home network work just fine, and we can get into any website with them. But ANY apple product is just stymied. We can turn off wifi on the phones, and get into websites with 3g, but as soon as the wife is turned back on, we're back to square one.
    Nothing has changed on our network recently, although we did get a new router about three months ago after having consistent outages. I have noticed our wifi getting glitchier and slower as time goes by,  but again, it affects the Apple products, until it just went totally haywire last week.
    My husband gets wifi at work just fine, and I am accessing wifi quickly and accurately on the MBP at this very moment on a museum network.
    The issue seems to be the AT&T home network, and very specifically with the full line of Apple products.
    Any clean and easy suggestions? I don't want to have to jump through hoops on four different products, and I now suspect it's something to do with AT&T?

    Pleeeeeeease. Somebody? Anybody?
         I can't get into Facebook, or Ebay on my MacBook. Life is too short to weep and lose hair over computers. Surely there's a quick fix I just haven't thought of?

  • Hello, I need help with my macbook pro. It looks like I cannot install anything anymore. Everytime I try to install a new software, use the migration assistant or click the lock to make changes, it simply does not react.

    Hello, I need help with my macbook pro.
    It looks like I cannot install anything anymore. Everytime I try to install a new software, I simply get stuck during the installation type process. I put in my password, it does accept it, but it does not go any further.
    I tried to reset the password, put no password, repair the permissions, the disk but nothing will do. I nearly got stuck with the log in screen but finally succeeded in disabling it.
    So I thought I might try to create a new account but I cannot click the lock to make changes. It simply refuses to react.
    I am now thinking about using the migration assistant to save all my settings, data and so fourth, but again I get stuck when I have to type in my password. It accepts it but nothing happens...
    I guess it has something to do with the authorization process, but can't find anything on the internet about it... Can you help me out?
    I am running Lion 10.7.3.
    Regards,
    Nicolas.
    (I apologize if any grammatical/structural mistakes were to be found, english is not my mother-tongue. )

    You probably won't like this suggestion, but I suggest you reinstall Lion.
    First, backup your system. Next, reboot your system, press/hold the COMMAND-R keys to boot into the Recovery HD. Select 'Reinstall Mac OS X'. If you purchased Lion as an upgrade to Snow Leopard, the reinstall process will install Lion 10.7.3. If your system came preinstalled with Lion, you might still get Lion 10.7.2. Both installs are a total install of the OS. None of your apps or data will be impacted. Just the OS.

  • I have screwed up a bunch of settings etc. on macbook pro running preinstalled lion. I think I should is to wipe the computer and reinstall to start over again. I will loose nothing of importance except a few passwords.  Is this wise? How do I do it?

    I have screwed up a bunch of settings, folders, photos, etc on my macbook pro running factory installed Lion.  To get everything straightened out, I was thinking I should do a delete and reinstall and just start over like it was a brand new computer.  I will only loose some usermane and password info and my history and cookies.  There is nothing else on the computer that is not on another device somewhere.  Does this sound like the right thing to do?  I cannot seem to find ways to correct the problems indivdually, though I am sure they are there.  If so, how do I do it?  My computer did not come with any type of disc, I do not believe.  Thanks in advance for anyone's help!

    Yes, that sounds reasonable.
    Install or Reinstall Lion/Mountain Lion from Scratch
    Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard 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.
    Erase the hard drive:
      1. Select Disk Utility from the main menu and click on the Continue button.
      2. 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.
      3. Set the format type to Mac OS Extended (Journaled.) Optionally, click on the Security button
            and set the Zero Data option to one-pass. Click on the Erase button and wait until the process
          has completed.
      4. Quit DU and return to the main menu.
    Reinstall Lion: Select Reinstall Lion/Mountain Lion and click on the Install button.
    Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.

  • Pleeease help! cant boot macbook pro running leopard!

    i am having a huge problem with my macbook pro running leopard. i was originally trying to partition my hardrive for windows with boot camp but that failed cause it "couldnt move files" so i ran disk utility with the installation disk to fix the harddrive.
    anyways next thing i know i boot my computer and it stops at the blue login screen before it has the option to login with the spinning wheel and does a loop of blue screens with spinning wheel. wont boot in safe mode and it always stops at the same screen. so i looked around on the web and it sounded like a had to archive and install. so i did that and then half an hour in it told me i had a corrupt file and i had to restart.
    so i restarted and then it brought me straight to the leopard installation screen and told me that "mac osx cannot be upgraded to v10.5 on your computer" because "macosx 10.4 or later could not be found"!!! i used the disk util to repair the hard drive but it said everything was fine. i cant safe boot, it wont give me the option to archive and install again its only giving me the option to erase my whole harddrive!
    pleeease help! i have not backed up in 2 months! is there anyway to get this to start up or back up some files from this point?

    Hello and Welcome to Apple Discussions ...
    Ok... if you have another Mac, you can do Firewire Target Disk Mode
    To transfer files using FireWire:
    Shut down the computer to be used as a disk. Leave the other computer on.
    Connect the two computers with a FireWire cable.
    Start up the computer to be used as a disk, then open System Preferences, click Startup Disk, and click Target Disk Mode. (Or, start it up while holding down the T key.)
    A disk icon appears on the desktop of the other computer.
    Transfer files by dragging them to and from the disk.
    Eject the disk by dragging its icon to the Trash. (While you drag, the Trash icon changes to an Eject icon.)
    On the computer you used as a disk, push the power button to shut it down, and then disconnect the FireWire cable.

  • What is the best application to optimize my Macbook Pro running Mountain Lion???

    What is the best application to optimize my Macbook Pro running Mountain Lion???

    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.
