  • Leopard Startup Problem on MacBook Pro 15" 2.5 GHz

    When secure deleting trash it took over 30 minutes to delete a 1 GB file so tried to stop. As this failed I pressed ctrl /cmd and power button to force a restart. On restart the computer starts but fails to get to login screen. Tried running ‘Disk Utility’ - on verify or repairing disk permission it reads:
    “Error: the underlying task reported failure on exit and a window with
    First Aid failed
    “Disk utility stopped verifying permissions on “Macintosh HD” because the following error was encountered”
    ‘The underlying task reported failure on exit’
    Verify and repair disk is OK it is just the permissions that have errors.
    On connecting to another Mac running 10.2.8 in firewire mode the other Mac indicates that the MacBook Pro disk is unreadable and do you want to initialise.
    Have also tried resetting PRAM and this does not rectify the problem.
    Pressing option at start up sees the drive but after selecting it I have the same problem as before.
    Tried installing from MacBook Pro Leopard install disks that came with the computer. On starting to do this it warns that a newer version exists on the volume (as I have the most recent version via software downloads) and that I need to click on options
    I selected the default ‘Archive and Install’ and ‘Preserve user and network settings’ but it fails to install reading ‘ Install failed MacOSX could not be installed on your computer’. The installer could not install some files in”/Volumes/macintosh HD” contact the software manufacturer for assistance.
    I would do a clean install but I would lose about 50 or so files that I have not backed up.
    I am hoping that there is a workaround rather than having to purchase DiskWarrior.
    As the computer is only 3 months old will Apple sort the problem out – can I take it into one of their stores to get this done?
    thanks in advance for any help you may be able to offer
    Cheers
    Dougie

    Your options:
    1. Use DiskWarrior to rebuild the directory or,
    2. Erase & Install.

  • Odd power/battery startup problem on MacBook Pro

    I have a MacBook Pro 15-inch, Mid 2012 running OSX 10.9.5 with all updates.  Approximately one year ago the battery died and I'd been operating off the adapter ever since.  This past Thursday I finally had a Mac hardware guy from the local university install a new battery; something he does regularly for the university's MacBook Pros.  Weirdly, the old battery had no bulges or other visible problems.  He did an SMC reset, started up, and everything worked fine.  I later hooked up a brand new Acer external monitor mirroring it to the laptop, and charged the battery to 100% with the Adapter.  That night I disconnected the adapter and all peripherals without shutting down to have the battery drain somewhat overnight.  Friday morning the laptop started up with a partially depleted battery.  So, I hooked up the adapter and peripherals.  All was well. I shut down Friday night and restarted yesterday, Saturday morning, but there was a little glitch with the mirroring settings.  I solved that problem by deleting the Library/Preferences/com.apple.windowserver.plist file and restarting.  However, in trying several scenarios to make sure the display mirroring settings were sticking, I suddenly noticed the laptop would now not start up on battery power despite the battery being charged.  It would only start up with the adapter attached even when all peripherals were disconnected.
    Today I have tried NVRAM and SMC numerous times with and without the adapter attached.  When the adapter is not attached the resets appear to be working (chime, grey screen, Apple logo) but then the laptop display dims for a second, then goes black.  The power light on the computer goes off.  So it appears the computer suddenly shuts down without completely starting up.  When I then attach the adapter, the computer starts up (and shuts down and starts up the exact number of times I tried either NVRAM or SMC or simply push the Power Button), finally starting up completely.
    The standard Hardware Test (with no peripherals but the adapter attached) and the extended Hardware Test show no problems.

  • Long startup problems on MacBook

    MacBook 10.6.8 startup goes to grey screen with apple, wheel and progress bar, and takes 5 minutes. This started only recently. What might be wrong?

    I suggest running Disk Utility's "Verify Disk" check to make sure the file system is OK. If it detects any problems, you need to start up from another disk, like your OS installer disk, & run Disk Utility's "Repair Disk" step from that.

  • MacBook pro when windows 7 has startup problem and Mac os doesn't work

    I installed windows 7 on my MacBook pro and it did work well. But now windows has a startup problem and "startup repair" couldn't solve it, so I can't use both Mac os and windows and my laptop has become completely useless. Any suggestion?

    Reboot and hold down command-R at the sound of the chime, that should take you to the Lion recovery partition, if it does go to disk utility and see if you have an OSX partition at all.

    This thing happend,, it say Disk utility stopped repairing "Macintosh HD" disk utility can't repair this disk
    Sorry, possibly you need a new hard drive or try reformating. First
    you can try something like http://www.alsoft.com/diskwarrior/  it has been known to repair disk that DiskUtility could not. YMMV and they don't give it away.
    If Disk Warrior can not repair then you need to Reformate the drive. Make sure you have a back-up in place no matter what.

  • Problems reformatting MacBook Pro recovery disk missing

    Hacing problems reformatting MacBook pro. Tried startup with option key but recovery disk option missing. Then tried the Mac os x disc that came with the MacBook Pro however when I get to the selection of where I want to install no HD option appears. Start up disk also appears to be missing. Can only start Mac in safe mode.

    Remind them at this time you don't desire a service account, just desire a disc.  The only reason you would want an account is if you wanted them to help you with actual troubleshooting.

    Slow performance after installing Yosemite on an older Mac is often caused by inadequate memory. Although you can install the upgrade on a Mac with 2 GB of memory, experience has shown that at least 4 GB is needed for full performance.
    Select About This Mac from the Apple menu. If you have less than 4 GB of memory, and your model has upgradable memory, install as much as it can take, or at least that much. Any reputable RAM vendor will have a web form in which you can select the Mac model and be directed to compatible parts.
    Memory in the MacBook Air is not upgradable. If that's what you have, you should restore the previous system from a backup, or replace the machine. Ask if you need guidance.
    The Etrecheck report clearly shows that SylvieRose has a Macbook Pro, not a Macbook Air and that there are only 2 GB  RAM installed.  The Etrecheck report can be very informative if one takes the time to examine it.

  • What is the problem on MacBook Pro retina 15"?

    I just bought a new MacBook Pro retina 15". After unboxing, I turned it on and there was no any problem. But the second time I turned it on and charge battery, I got 2 problems, 1. The machine made noise loudly and 2. The charging is not working. What is the problem on MacBook Pro retina 15"? However, after about 1 hour, it works normally. Should I still use it or sell it before it has more issues?

    The warranty entitles you to complimentary phone support for the first 90 days of ownership.
    If you bought the product in the U.S. directly from Apple (not from a reseller), you have 14 days from the date of delivery in which to exchange or return it for a refund. In other countries, the return policy may be different. If you bought from a reseller, its return policy applies.

  • How do i turn off the startup sound on macbook pro?

    how do i turn off the startup sound on macbook pro?

    You don't. You may find some third-party software that will, however. Try Auto Mute.
    Alternatively, you can try this:
    I think this is the best and simplest solution. Open a Terminal window and type (or copy/paste) the following to turn down the startup noise:
         sudo nvram SystemAudioVolume="%00"
    Press RETURN.
    And to restore it to the original value type:
         sudo nvram -d SystemAudioVolume
    Press RETURN.
    That's all folks.
