Mac wont start up

My Macbook pro wont get past the apple start screen. I hear the chime and the apple pops up and it just never stops loading. I've tried turning it off and on, starting it in safe mode, and starting it through the Mac OS X DVD. by putting the dvd in and holding option, I saw that it does recognize my hard drive, and it recognized the dvd as well, but when I try to start either of them, it can't get past the loading screen. How can I get the machine past the loading screen?

Battery full - Mac wont start. Heeeelp!

I just purchased my MacBook a month ago and I love it. Now Im having a problem...
I just had this problem today. The battery is full but my Mac wont start. But when I connect it to the power adaptor - it will start. Should I change something on the Energy saver option?
I've tried to remove the battery and placed it back, but the problem is still the same. I need your help please... thanks in advance.

Yup, looks like you've joined the Macbook Shutdown/won't boot club. Mine did the same after the random shutdown problem. I reset the PMU and NVRAM and PRAM and suddenly it wouldn't boot or operate on battery. Let me guess, it works fine on the adapter, but when you pull the plug it immediately shuts down, right? Even though the battery is fully charged? I'm also from DK. Did you buy yours at Humac? Mine is being repaired as we speak, well actually it's waiting for parts (new logic board and battery) but it's taking forever. Turned it in on july 25th and it is still waiting for parts. My advice is to demand a new one, don't hand it in for repair, because I seriously don't think they know what is wrong yet. What week is your Mac(Check the serial-number and post it)?
I've heard that a lot of people got the LB replaced, but soon after the problems started again.

My Mac wont start! what can i do?

My Mac wont start! After i restarted it for a update it just crash when i try to start it what can i do?

What and why aren't people doing something simple that has worked for the last 10 yrs:
Clone your system before you ever apply updates
Always have a working bootable backup (or two)
Keep the prior version on the shelf
Keep the combo updates around also.
It is not hard or rocket science.
There is no mechanism to undo rollback or restore check points. No utility to sandbox updates and revert as they sometimes go wrong. Things that are overdue.
MicroMat made having an "eDrive" partition s sinch to do and was its own recovery/emergency boot partition.
Carbon Copy Cloner has been around since 10.2.2, and later SuperDuper and others, Clone X etc.
A clean install is simple. Keeping your emergency boot drive for maintenance updated but with just Apple OS and essential drivers.
Use Safe Boot beforehand. People used AppleJack before updates or at first freeze or sign of trouble.
If you have more than enough room for TimeMachine, then a couple options:
Set aside 35GB is more than enough for emergency boot maintenance (Lion Recovery is nice but doesn't have everything your toolbox might want or need)...
Set up a partition large enough for your working system, again 40-80GB should be enough, you won't clone everything as you can leave your home account folders for TimeMachine if you want (but do want to copy your home Llibrary ~/Library). perfect job for Carbon Copy Cloner.
Setting up an external boot drive is 101 along with TimeMachine.
Not a good idea to have all your eggs in one basket two or more backup drives is better but...
TimeMachine - 350% your total files and changes needed to have file history archived,
Emergency OS
Clone OS
I prefer a 1.5TB minimum.would do fine for most.

orshikhfromsc,
boot from the Mac OS X Install DVD that originally came in the box with your MacBook Pro (by holding down the C key as it starts up). When the desktop appears, select Disk Utility from the Utilities menu and erase your internal disk. After it’s been erased, reformat it. After it’s been reformatted, exit Disk Utility and reïnstall the version of Mac OS X from that DVD onto your internal disk. After that version of Mac OS X has been reïnstalled, boot from your internal disk and run Software Update to get it up-to-date within that version; that should allow you to redownload and reïnstall Mavericks, if desired. If Mavericks is reïnstalled, run Software Update again to get it up to date.
If you no longer have the two grey installation DVDs, you can purchase a replacement set from either Apple or iFixit.

Power Mac wont start up

My power mac G5 wont start up. When i turn it on it comes up with a message saying you need to restart you computer and a load of script drops down in the top left hand corner. I cant get past it and tried everything. This happens everytime i turn it on.
HELP!!!!!

Hi-
Welcome to Discussions!
Have you-
1- Removed/disconnected all devices, except for keyboard, mouse and monitor?
2- Checked your panic log? You can check the kernel panic log any time that you must force restart your computer, using either the power button, interrupt button, or the Control-Command-power key combination. The kernel panic text is added to the log the next time you restart the computer, assuming that you have not reset PRAM at the same time (the kernel panic text is stored in PRAM until you restart). The file is named "panic.log", and it is located on your startup disk at: /Library/Logs/.
The panic report is also the "script" that is displayed when the "restart your computer" message appears. A copy of the report would help.
3- Tried a "safe boot"? Hold down the "shift" key when starting.
http://docs.info.apple.com/article.html?artnum=107393
4- After checking the panic log, try resetting the PRAM:

If you can get to the panic log, possibly during a safe boot, record the log, especially everything after "backtrace":

please help

I fully agree with BDAqua.
Don't do anything with this Mac until you have an external disk which you can boot your Mac from.
Not all USB disks are easy to boot from - FireWire is better
When you have a suitable empty external disk I advise:
Put install DVD into damaged Mac
partitioning external disk into 2 volumes
install OS onto one volume of external disk
Don't import anything during install process - it may reintroduce historic problems
Boot external disk
Use finder to copy critical data from Mac to volume of external disk with OS
Use Carbon Copy Cloner to clone the whole Mac hard disk to the other external volume
Boot into installer DVD and erase Mac's internal disk
Partition internal disk into 2 volumes and install OSs as required

My start up disk is full and my mac wont start

Hi My start up disk is full and my computer wont start how do I get the system to reboot again?

Ensure that the external is correctly formatted
Drag and dropped the files
Test to be sure that the moved files work
Once the moved files work delete the originals

Mac wont start if ADC is not Connected??

I have a G4 Quicksilver Dual processor, with Tiger OSX installed on it. The video card installed has a ADC and VGA connector. I recently wanted to change from the ADC monitor to the VGA(new PC Monitor). But when the apple display is not plugged in the computer wont start.
Why
I have done all the system preference stuff and changing secondary to primary and even swapped video cards with another machine which i know works with the VGA connection.
Please Help
Cheers

I do not believe it's the Graphic Card, I think it would need either a new Logic Board or Power supply.
Which card is it exactly, some can run both monitors at once.
And there may be a slight possibility that a Keyboard like this with a "Power Key" at the top right corner may work to start it...

My apple i mac wont start as normal it makes three beeping sounds

my apple I mac 2009 won't start up normally it makes three loud beeps

Remove and reinsert the computer's RAM. If that doesn't work, use different modules.
If that only happens when you try to boot the computer to a specific Mac OS X version, it's too old.

Stupid mac wont start

when i press the power button on my macbook i'll get the gray screen with apple in it...
and few seconds later it turns into a weird sign and nothing happens. and it just stays there.
its worth mentioning that i've updated my mac a day before. though i did restart and shut down several times on the day before having that problem.
how to solve it? I need to use the computer.
i'm glad this pc is working
*hugs pc*

I got this sign while booting …
Unfortunately your link gives me an error that I am not allowed to view that page. But I suspect you are talking about the sign shown in this KB article:
Mac OS X: 'Broken Folder' Icon, Prohibitory Sign, or Kernel Panic When Computer Starts Up.
See if anything in that article helps.
i'm really afraid if i do anything I might kill the macbook
A Safe Boot should not do any harm, as you will see from the articles I referenced. But I do not have Windows installed so I can't speak for that. If you're still not sure, perhaps you should try the Macbook forum?

My Mac wont start, seems to be stuck in sleep mode

Hello there,
So just recently my computer died while in sleep mode. I put it on the charger and let it be. However, now when I turn on the power it seems like it is stuck in sleep mode, there is no connecting chime (when powered up) the keyboard fails to work as a means of getting the notebook to start up. The fan and or disk is running really slow at first but then gets louder. I am not skilled with my Mac, was wondering if there is an easy fix or I should get on my way to the repair store.
PS - I have tried the command+option+escape to kill all the apps running but that seems to not work? anything else i should try?
Please help.

Hold down the Power button for 10 or 15 seconds until the computer shuts down. Then restart it if possible. If it won't restart then make a Genius Appointment and take it in for service.
