Mac book locking up require restart

my mac book locks up with a must restart error. sometimes after mac goes into sleep or screen shutdown but I have had it happen running different apps. any body else have this problem. I thought I had random shut down problem but my mac only locks up. I have unistalled bookcamp to see if that fixes it.
Thanks

Sounds like you are having kernel panics. Have you added any third-party RAM? They are usually hardware related.

Also, try this to make sure your hard drive's directory is OK.
Boot from your system CD, run Disk First Aid and repair your permissions.

I'm downloading the OS X Mavericks then in the process of downloading till 4.20GB it stops and shut down my Mac Book Pro and automatically restarted

i'm downloading the OS X Mavericks then in the process of downloading till 4.20GB it stops and shut down my Mac Book Pro and automatically restarted. Any answers for this?

The download is over 5GB's so yours is incomplete.
You should be able to resume the download (instead of starting over) at the App Store.

Downloaded and installed os x yosemite and now mac book pro will not restart? How long should this take? Is there something wrong? Please helpthanks in advance

MAc book pro. I have downloaded and installed os x yosemite now mac book pro will not start? How long should it take? Is there something wrong?

The 2 computers here took about 45 minutes to an hour each.
The best thing to do is give it more time. If it gets too ridiculous, shutdown using the power button and then restart. Check  menu/About This Mac to see if it is installed.

Help!!!!!!!! Just did update on computer mac book, then went to restart and will come on but with turn off and restart over and over and over

just did update to my mac book, then clicked ok to restart, but the computer came on then will turn off again then come back on and turn off over and over again
HELP PLease!

Turn the computer off by holding down the power button, then get your original DVD that came with the Macbook insert it in the DVD drive as soon as you can and then hold down the "C" key while the computer restarts and then run disk utility on your hard drive, also repair your permissions.

Mac Book Pro does not restart

When I try to restart my mac book pro, it doesn't restart. It will shut down and bring up the grey screen, but will just hang on the grey screen. I then have to power down the computer and then power it on again. I called Apple Care and they had me repair permissions on the Hard Drive, and verify the permissions. We trashed the cache folder from the library. We restarted and the same thing happened? The apple care said I would have to an archive and install from the original disks, this seems to me to be overkill. Does anyone have any experience with this problem?
Cheers

I just found this link, seems to be working for me, for now. It will delete all of your login items to remember what they are so you can populate the list again..

Mac Book Pro won't restart after GPU Panic

I have a 2010 Mac Book Pro with a known issue of GPU Panics, especially following Mavericks installation.
Have been limping along with band aid solutions until I can get a new computer, but today, following a panic, the laptop won't restart.
I press the start button, get the usual startup sound, get gray screen with Apple logo, gray spinning pinwheel for about 2 minutes, and the screen goes totally black. Machine still seems to be on, makes quiet noise.
Any ideas on how I can get it to restart?

Katharine,
since you currently have Mavericks installed, you can try this: boot your MacBook Pro into Recovery mode by holding down a Command key and the R key as it starts up. Once the Mac OS X Utilities menu appears, select Disk Utility. On the left-hand side of the Disk Utility window, select your internal disk’s boot partition (typically called “Macintosh HD”). On the right-hand side, press the Verify Disk button if it’s not greyed out; if it is greyed out, or if it reports that errors were found, press the Repair Disk button. Once the verification/repair is completed, exit Disk Utility and select Restart from the Apple menu to restart in normal mode. Does it reach the login screen now? (Your screen going totally black is probably due to the GPU problem.)

Mac Mini Server VPN requires restart of service after each reboot

Mac mini Server (Late 2012)
OS X 10.8.4
After a reboot, when viewing in Server.app, VPN service is turned on, however no connections can be made until the service is turned off then back on again.
VPN service log entry shows "Listening for connections..." but doesn't allow incoming VPN calls until the service is restarted.
Anyone else having similar issues or have suggested solutions?
Thanks much!

Mac book air crashed, when restarted it gets stuck on grey screen

I was using my MacBook Air (mountain lion osx) this afternoon as normal when the screen froze on me as if the computer had crashed. After a minute or two I decided to restart it by holding down the power button. The air turned off and back on, and got the the grey screen with the apple symbol as if it was re-booting but has been stuck there ever since?.
Any idea what's happened and how to resolve please.
Thanks in advance.

Take each of these steps that you haven't already tried. Stop when the problem is resolved.
Step 1
The first step in dealing with a boot failure is to secure your data. If you want to preserve the contents of the startup drive, and you don't already have at least one current backup, you must try to back up now, before you do anything else. It may or may not be possible. If you don't care about the data that has changed since your last backup, you can skip this step.
There are several ways to back up a Mac that is unable to boot. You need an external hard drive to hold the backup data.
a. Boot into the Recovery partition, or from a local Time Machine backup volume (option key at startup.) When the OS X Utilities screen appears, launch Disk Utility and follow the instructions in this support article, under “Instructions for backing up to an external hard disk via Disk Utility.”
b. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, boot the non-working Mac in target disk mode. Use the working Mac to copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
c. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.
Step 2
Press and hold the power button until the power shuts off. Disconnect all wired peripherals except those needed to boot, and remove all aftermarket expansion cards. Use a different keyboard and/or mouse, if those devices are wired. If you can boot now, one of the devices you disconnected, or a combination of them, is causing the problem. Finding out which one is a process of elimination.
If you've booted from an external storage device, make sure that your internal boot volume is selected in the Startup Disk pane of System Preferences.
Step 3
Boot in safe mode. Note: If FileVault is enabled on some models, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Post for further instructions.
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
When you boot in safe mode, it's normal to see a dark gray progress bar on a light gray background. If the progress bar gets stuck for more than a few minutes, or if the system shuts down automatically while the progress bar is displayed, your boot volume is corrupt and the drive is probably malfunctioning. In that case, go to Step 5.
If you can boot and log in now, empty the Trash, and then open the Finder Info window on your boot volume ("Macintosh HD," unless you gave it a different name.) Check that you have at least 9 GB of available space, as shown in the window. If you don't, copy as many files as necessary to another volume (not another folder on the same volume) and delete the originals. Deletion isn't complete until you empty the Trash again. Do this until the available space is more than 9 GB. Then reboot as usual (i.e., not in safe mode.)
If the boot process hangs again, the problem is likely caused by a third-party system modification that you installed. Post for further instructions.
Step 4
Sometimes a boot failure can be resolved by resetting the NVRAM.
Step 5
Launch Disk Utility in Recovery mode (see Step 1.) Select your startup volume, then run Repair Disk. If any problems are found, repeat until clear. If Disk Utility reports that the volume can't be repaired, the drive has malfunctioned and should be replaced. You might choose to tolerate one such malfunction in the life of the drive. In that case, erase the volume and restore from a backup. If the same thing ever happens again, replace the drive immediately.
This is one of the rare situations in which you should also run Repair Permissions, ignoring the false warnings it may produce. Look for the line "Permissions repair complete" at the end of the output. Then reboot as usual.
Step 6
Reinstall the OS. If your Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
Step 7
Repeat Step 6, but this time erase the boot volume in Disk Utility before installing. The system should automatically reboot into the Setup Assistant. Follow the prompts to transfer your data from a Time Machine or other backup.
Step 8
This step applies only to older Macs (not current models) that have a logic-board ("PRAM") battery. Both desktop and portable Macs used to have such a battery. The logic-board battery is separate from the main battery of a portable. A dead logic-board battery can cause a gray screen at boot. Typically the boot failure will be preceded by loss of the startup disk and system clock settings. See the user manual for replacement instructions. You may have to take the machine to a service provider to have the battery replaced.
Step 9
If you get this far, you're probably dealing with a hardware fault. Make a "Genius" appointment at an Apple Store to have the machine tested. If you can't get to an Apple Store, go to another authorized service provider.

My 2010 mac book pro keeps on restarting

Essentially the computer keeps on restarting, its taken three goes to submit this question -   i have read previous entries re graphic card enablers/disablers but they haven't helped. Here's the error message I hope someone can tell me what the exact problem is and the best way to manage the problem.

You have the MacBookPro6,2—the Edsel of Macs. It may have the logic-board defect that was covered by this recall.
Make a "Genius" appointment at an Apple Store, or go to another authorized service provider, to have the machine tested. The routine hardware diagnostics used by service providers do not detect the fault. There is a specific test for this issue that Apple calls "VST" (for "Video Switching Test.") Ask for it. A "Failed" result means that the fault is present. However, according to reports, some units may pass the test, and yet still be deemed eligible for repair under the program. Your experience may vary.
Print the first page of the panic report, if any, and the support page linked above, and bring them with you.
Note that the recall only applies within three years of purchase. After that, Apple may refuse the service. In that case, you may be quoted a price of about $300 (in the U.S.) for a "depot repair," which involves shipping the unit to a central repair facility and takes about two weeks. For that flat fee, anything found wrong with it should be fixed, not just the logic board.
The model was discontinued on February 24, 2011, so the recall has nominally ended. Some units may have been sold after that date by Apple as refurbished, or by resellers as new, and they might still be covered.
Some owners report that their unit was repaired under the program after the deadline had passed. Others report that the repair was covered by the extended warranty from a credit-card issuer. Again, your experience may vary.
Sometimes the replacement part is also defective, so be prepared for that possibility. If you decide to pay for a new logic board, test thoroughly during the 90-day warranty period on the repair. Some owners have reported that they went through as many as three replacement boards before getting one that worked.
If it's too late for your unit to be repaired free of charge, and you don't want to pay for the service, you may (or may not) be able to stop the panics by disabling automatic graphics switching. To use the discrete graphics processor, you'll need a third-party utility to switch to it manually.
Often the problems start after an OS upgrade. If the upgrade was recent, and you have backups, then you can revert to a previous OS X version.
If you're dissatisfied with Apple's response, please keep in mind that no one here represents the company or can help with customer-service issues.
Back up all data on the internal drive(s) before you hand over your computer to anyone. If privacy is a concern, erase the data partition(s) with the option to write zeros* (do this only if you have at least two complete, independent backups, and you know how to restore to an empty drive from any of them.) Don’t erase the recovery partition, if present.
*An SSD doesn't need to be zeroed.

My mac book froze. I restarted with no success. I put in the install disk and its still frozen. Please help!

Please help. I don't want to pay to at store when the tech guy over the phone said it sounded like an easy fix. Never had a problem with this computer before. Hope someone can help!

If the disk hardware is working properly but the directory on it is very badly scrambled, it might take as much as an hour, though less than half that amount of time is more common. But if the disk hardware is failing, Disk Utility won't be able to repair it at all, and it may keep trying for a very long time (hours) before giving up.

What is your Machine ID? DO NOT give us your serial number. We just need the x and y values of the Machine ID in your system profiler as given in this format:
MacBook Pro x,y
This will tell us what display cables can connect to your TV.

Mac book keeps restarting because of problem

I'm running Mavericks and safari keeps reloading web pages and now my Mac book shuts down and restarts on its own.

These instructions must be carried out as an administrator. If you have only one user account, you are the administrator.
Launch the Console 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 Console in the icon grid.
If you don't see any reports listed, but you know there was a panic, you may have chosen Diagnostic and Usage Messages from the log list. Choose DIAGNOSTIC AND USAGE INFORMATION instead.
In the Console window, select
DIAGNOSTIC AND USAGE INFORMATION ▹ System Diagnostic Reports
(not Diagnostic and Usage Messages) from the log list on the left. If you don't see that list, select
View ▹ Show Log List
from the menu bar.
There is a disclosure triangle to the left of the list item. If the triangle is pointing to the right, click it so that it points down. You'll see a list of reports. A panic report has a name that begins with "Kernel" and ends in ".panic". Select the most recent one. The contents of the report will appear on the right. Use copy and paste to post the entire contents—the text, not a screenshot.
In the interest of privacy, I suggest that, before posting, you edit out the “Anonymous UUID,” a long string of letters, numbers, and dashes in the header of the report, if it’s present (it may not be.)
Please don’t post other kinds of diagnostic report.
I know the report is long, maybe several hundred lines. Please post all of it anyway.

Mac Book pro locks up after pressing restart button at login.

I have a MacBook Pro, and I was just logging into my computer when I decided instead of putting my password into the login screen I clicked the back button, I then proceeded to press the restart button from the login screen to restart my computer, but then the courser disappears and the screen starts to darken slowly, (and not from the monitor's lights dimming), from top to bottom. A gray message pops up with a picture of a mac power button behind it and typed in all different languages it says, "Please hold down the power button for a few seconds to shutdown your computer." or something like that. I am sure it is an official message from apple and I have had this before but I think this is a major bug that apple might have missed or maybe I just haven't heard of the solution yet. BUT IT ONLY HAPPENS WHEN I ATTEMPT TO RESTART FROM THE LOGIN SCREEN. If anyone is having this same problem I would like to hear about it or if you have any suggestions on how to fix this issue that would be great, Thanks.
PS: This error does not seem to affect my friends mac book.
