Question about Apple MacBook Pro Laptop Computer with Intel Duo Core 15.4 Inch PC Notebook

1 Answer

My macbook pro OS 10.6.4 either freezes or crashes on startup. Crashed when trying to startup with Drive Genious 3, TechTool Pro 5, System Disk or Disk Warrior. Not sure what to do next. Tried holding shift key down during startup but that did not help.

Restart your mac. As it's restarting/booting up, hold down the command, option, R and P keys simultaneously. As it's booting up and you're holding these keys, you should hear the startup chime, continue to hold the keys down, it will cycle and you'll hear the startup chimes again. Let it go thru this cycle 7 (seven) times before you let up on those keys. Once it's cycled 7 times, let it boot up normally.
If that doesn't work, then reinstall the original system software that came with the Macbook. You may have to reformat the hard disk and do a clean install.

    I've had this problem now a couple of times. It happens after the laptop has been put to sleep by closing the lid. It often struggles to wake up from sleep, but this is the most severe phenomenon. I press redraft and it eventually gets to the login screen (usually after several presses to the on button), but then immediately crashed before I can log in. I tried holding the keys you recommend but the behavior didn't change. Any other ideas?

    Hopefully, you've backed up all your important data. Because what I'm about to tell you will destroy everything on your hard drive. If you've tried everything I've suggested, short of reinstalling the system software and nothing has worked. Then, there is but one option left.
    Take disk 1 of the system software disks that came with the computer, put into the optical drive and press the power button on the computer to start the computer up. While booting up the computer, you should press the "C" key on your keyboard and hold it until you see the Apple logo on the computer screen. Allow the computer to boot up and follow the prompts to do a NEW install of the system software only. You don't want to add all the associated software that come with the computer just yet (muddies the water so to speak). You can add those later, once we've addressed and eliminated the problem. Do a clean install of only the system software. Follow the prompts as the computer completes the process. Once it is done, reboot the computer. Complete the setup using setup assistant and input all your pertinent personal info. Once you've completed this process and have gotten to the desktop, reboot the computer.
    You should have to login since you haven't setup user account yet, so just reboot and get the to the desktop. Do this three or four times to make sure the computer is booting correctly and there are no issues. If so, then you may proceed to install the accompanying software that we skipped earlier. But install each package one at a time, not all of them at once. Each time you install one, reboot the computer and see if there are issues or the computer reboots normally.
    Repeat this process with each piece of additional software you install. Complete the installation and reboot the computer to check that the computer has no issues with the new software.

    If you do this and it DOES NOT resolve your problem, then I would venture to say that you have problems with the main logic board, or the CPU. (Of course, I saying this sight unseen, never having seen, nor laid hands on your computer) But that would be a strong possibility! I would then take it to a shop and have them test the computer. Don't give them too much information, just tell them it's not booting and have them test it and tell you what's wrong with it. Specifically, you want them to run tests on the Main Logic Board, the CPU and the RAM.

Factory reset button on macbook pro


There is no 'Factory Reset' button as such. If you are running OS 10.7 to 10.10, then you need to start up from the 'recovery' partition (CMD+R) on startup. You will then be able to erase the hard drive using 'Disk Utility' and then re-install the OS.

Apple Macbook pro beeps 3 times then freeze with I open Google drive app


First try clicking on your desktop, then Go menu (at the top of the screen), then Utilities, then double-click Disk Utility. Select your hard drive on the left, then you should be in the First Aid tab/pill on the right, then click the "Repair Disk Permissions" button (and restart for good measure when it's done). If it the only app that does this, maybe delete it and get the newest version?

Troubleshooting can be tedious and not usually one question/one answer; perhaps the easiest path to your fix is to backup your data (use Time Machine or just copy what you want to keep; if you don't have a drive, spend the $100 via Amazon slash dp slash B00CGUMS48).

Once you have your data, clean slate your Mac (boot to the system DVD or USB that came with your machine; or, you can just get Maverick (which you can download, but not install (leave in Applications), then connect a 8GB USB stick (Amazon B00DYQYJ3Q) that *doesn't* have data that your care about, then run a command in Terminal: sudo /Applications/Install\ OS\ X\ Mavericks.app/Contents/Resources/createinstallmedia --volume /Volumes/THENAMEOFYOURUSBSTICKHERE --applicationpath /Applications/Install\ OS\ X\ Mavericks.app --nointeraction).

Hopefully makes sense, and clean slate may not fix (but should, just install the faulty app and run it); so, that would mean something like faulty memory (where a strong program might dip deep enough to manifest), but clean slate is a wonderful thing.

Flashing folder when i turn on mac


Your hard drive may have crashed or it's settings have changed so it is no longer recognized as a startup (boot) drive. Try starting from your original operating system CD. (or borrow one). Press the C button at power up to force your computer to start from the CD.
Once started, don't install the operating system. Go to the pull down menu's and select Disk Utility. If Disk Utility sees your hard drive, select it and run the repair disk program. If it doesn't see it, your hard drive has likely crashed. You will have to replace it, install a new copy of the operating system, and likely have lost all your data and documents. This is where I would start.

Mac laptop screen froze with message stating must turn off laptop


font.f1 { font: 12px Helvetica; } Thanks for asking your question with Fixya Support. I will be glad to assist you.

What you are experiencing is what is called a Kernel Panic.
A Kernel Panic, is a internal fatal error, detected by your system from which it
cannot recover from safely. Such an error can be the result of a software
function or operation failing to execute as it normally does, or halting without
warning, or even a hardware component, suddenly ceasing to operating
or simply shutting down. In either scenario, the system will display the frozen
black and white screen with the languages text listed.

Normally a simple reboot of your Macbook Pro will resolve the issue, but in some cases it can take a specific procedure to correct and prevent a kernel panic from occurring again.

So here are a few procedures you can use to resolve and prevent further kernel panics:


• First, hold in your power button for approximately 10 seconds to do a hard shutdown, if your Macbook Pro is still turned on.

• Once your Mac is shutdown, you will need to perform what is called a PRAM reset (Parameter RAM)

• Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously .

• Turn on the Macbook Pro.
• Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.

• Now, hold the keys down until the computer restarts and you hear the start up sound for the third time.

• Release the keys and allow the Macbook Pro to start up.

If your Macbook Pro starts up normally and does not go into another kernel panic, then you should be able to resume normal session activity on your Macbook Pro.

However, should the kernel panic return, then you can use an SMC Reset to correct the kernel panic:

-SMC RESET-
The System Management Controller is an integrated circuit (computer chip) that is usually on the logic board of your Mac portable.

It is responsible for power management of the computer. It controls back-lighting, hard disk spin down, sleep and wake, some charging aspects, trackpad control, and some input/output as it relates to the computer sleeping.

Shut down the computer.
• Disconnect the MagSafe power adapter from the computer, if it's connected.
• Remove the battery.
• Press and hold the power button for 5 seconds.
• Release the power button.
• Reconnect the battery and MagSafe power adapter.
• Press the power button to turn on the computer.

Once again, when you are back up to your main desktop, resume your normal session activity.
At this point there should be no further issue a the kernel panic rearing its ugly head once again.

If it does, then you will need to take more intensive steps such as inserting your Mac OS X installation disc and booting up to that disc and running Mac OS X's Disk Utility, to repair the hard drive and permissions of the Mac OS X system you are using.

I will leave you with that procedure, in the event you need to run Disk Utility:

Insert your Mac OS X Startup disk
•Reboot your Mac
•At the Apple Chime, press the C key and hold it until you see a White screen, gray Apple and eventually a Spinning gear.
• Release the C key only after you see the Spinning gear.
•Mac will boot from the start up disk to the Installer environment
• From the Installer Menu bar, click Utilities > Disk Utility and open up Disk Utility application.
• Click on on the hard drive at the top of the window in the left sidebar and
• Select "Repair Disk"
**Let Disk Utilities run this repair the disk until completion
• At the end of this process, reboot your Macbook Pro
Return back to you main desktop and again, resume your normal session activities.

Any more kernel panics after this, you may want to consider taking your Macbook Pro in for service at your local Apple retail store Genius Bar or local Apple authorized service provide in your area.

I hope this information proves helpful for you.

Regards,

Hard disk crashed on macbook


You can tell if your hard drive for your Macbook Pro has really crashed, if you attempt to run these 3 diagnose and repair procedures and there is no response from the hard drive:

1st Procedure:

font.f1 {font: 12.0px Helvetica} font.f2 {font: 14.0px Myriad Pro} - USING FSCK COMMAND TO VERIFY AND REPAIR DISK-
Start up your computer in Single-User Mode to reach the command line by doing this:
•Make sure your Mac is shutdown.
• Reboot your Mac
• When Mac starts up, press the Apple Command key+ S Key
- A black screen, with white text appears
• At the command-line prompt, type /sbin/fsck -fy
• Press Return.
--fsck will run through a series of tests and will return information about your disk's use and fragmentation. When completed, it will display this message if no issue is found:

The volume (name_of_your_Mac_volume) appears to be OK

If fsck found issues and has altered, repaired, or fixed anything, it will display this message: --FILE SYSTEM WAS MODIFIED--

Important: If this message appears, repeat the fsck command you typed at the beginning, until fsck tells you that your volume appears to be OK (first-pass repairs may uncover additional issues, so this is a normal thing to do).

• When fsck reports that your volume is OK, type reboot at the prompt and then press Return.
• This last command after completing the fsck process, is going to attempt to boot your Mac to the main desktop.

If unable to reach your Desktop with the fsck procedure, go to the next step.
----------------------------------------------------------------------
Procedure # 2
font.f1 {font: 13.0px Myriad Pro}
-RUN DISK UTILITY WITH STARTUP DISK-

Insert your Mac OS X Startup disk
•Reboot your Mac
•At the Apple Chime, press the C key and hold it until you see a White screen, gray Apple and eventually a Spinning gear.
• Release the C key only after you see the Spinning gear.
•Mac will boot from the startup disk to the Installer environment
• From the Installer Menu bar, click Utilities > Disk Utility and open up Disk Utility application.
• Click on on the hard drive at the top of the window in the left sidebar and
• Select "Repair Disk"
**Let Disk Utilities run this repair the disk until completion
• At the end of this process, reboot your Mac

* If you have still not gotten a successful boot to your main desktop, try this final step.
----------------------------------------------------------------------
Procedure # 3
My recommendation for this issue, is that you use the Archive and Install procedure to resolve this issue.

What this process consists of (using your Mac OS X install disc),is removing the damaged or corrupted Mac OS X directory and replacing it with a brand new directory.

This procedure also allows you to save your applications, files and folders without the old directory interferring with you then accessing those files.

-ARCHIVE AND INSTALL-

• Start up from your Mac OS X Install Disc 1 or Install DVD. Please remember to use the install disc that matches the current operating system your system haves.

Usually, you can start from the disc by putting it in your computer, restarting, and holding the C key.
• Hold the C key until you see a White screen, with a Gray Apple icon and eventually a Spinning gear.
• Release the C key only after you see the Spinning gear.

-Your mac will now boot from the disc and load into the Installer environment.

• Select your language. The Welcome to the Mac OS X Installer window appears.
• Click Continue. The Important Information window appears.
• Follow the prompts until you get to the licensing agreement screen
• An agreement sheet appears. If you agree with
the license agreement, click Agree. Then Select a
Destination window appears.
• Click the volume that you wish to install to (your primary hard drive).
• Click Options. The installation options sheet appears.
• Select Archive and Install.
• Select the volume which already has Mac OS X installed.
• You should also select Preserve Users and Network Settings, to preserve network and Home directory settings.

• Click OK.
• Click Continue to begin the installation.
• Once the Archive and Install is completed, when you reach your desktop be sure to run all Software updates to bring your new Mac OS X directory back
up to current.

Also, if you look inside your Macintosh HD icon on your Desktop, look for a folder entitled "Previous System Folder" which will have all of your previous Home folder files prior to the Archive and Install.

Here is the link (below) from Apple for more information about how to locate the Previous System Folder

How to locate Previous System Folder (after Archive and Install)
----------------------------------------------------------------------
If there is still no responsiveness of the hard drive after this last procedure, your best option would be to take your Macbook Pro in for repair or replacement of the hard drive, to your local Apple retail store Genius bar or local Apple authorized service center.

Best Regards,

I have a gateway lb3 500 ancient 98se i tried to load xp pro and it crashed i cant seem to even get a 98 startup disk to work to recover it . how can i recover it to load the xp pro onit


Try running linux on it. Linux will run much better on older hardware. Depending an the specs of the system, it may not be able to handle running windows. Try ubuntu (www.ubuntu.com). If it used to run Windows XP or 98 and it wont now, try checking the hard drive. It may be corrupt. You can find hard drive check tools all across the web, google for drive fitness test by hitachi, it works great. Burn to a disk and boot to it on the older machine and do a full advanced test on the drive.
