I can't turn on my Mac Book Pro. If I press the power button will beep 3 times (won't turn on) stop and beep 3 times again. What can I do?
Three beeps at startup almost always indicate bad RAM. You probably need to get your RAM replaced. Bring it in to Apple for a definitive diagnosis if you are unable to run the Apple HardwareTest

Yes if your model MBP has a removable battery. If it does not:
Shut down the computer.
Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected.
On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.
Release all the keys and the power button at the same time.
Press the power button to turn on the computer.
Note: The LED on the MagSafe power adapter may change states or temporarily turn off when you reset the SMC.

Mac Book Pro starts up to white screen then makes a sound and dies, turning off
Hello, my macbook pro is new, bought in August 2011. Just recently my battery died prematurely after only 118 cycles. However, the hard drive also had to be replaced as it wasn't for some reason working with the battery. Now, my computer even though the battery works and I've passed all my documents to the new hard drive is having problems when it starts up. It makes the typical apple sound when it turns on and it goes to the white apple screen and unexpectedly dies off (turns off). It makes a sound as if everything is starting off then a dying sound when it turns off. Sometimes I try it again and it turns off or it can also turn on randomly and fully boot. Holding the shift, control and alt key while it is connected to the battery until the charge changed color works but it is not a permanent solution as this problem has continued for a week. It occured a couple of days after replacing the hard drive and battery at the genius bar. Any help?
It is better to take it back to the genius bar.
Your MBP is under warranty and let them fix it for you.
Nobody here can help you with hardware problems.

Mac Book Pro won't start from hard drive when turned on
I have a new 15 in Mac Book Pro with 10.8.1. When I turn it on it always boots to the disk utilities rather than my harddrive. I select my startup disk and reboot. It starts fine. But when I shut it off the same sequence repeats. I have verified my drive and selected the hard drive as my startup disk.

After updating my mac book pro to the osx yosemite.am getting some issues after starting up.as soon as it gets on the destop the screen start blinking and i cant do anything.Please help me!
Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you turn on the computer, and again when you log in.
Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a Fusion Drive or a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to start up and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal startup may also be somewhat slow.
The login screen appears even if you usually login 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.
Test while in safe mode. Same problem?
After testing, restart as usual (not in safe mode) and verify that you still have the problem. Post the results of the test. -

off againReinstall Snow Leopard without erasing the drive
1. Repair the Hard Drive and Permissions
Boot from your Snow Leopard Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
2. Reinstall Snow Leopard
If the drive is OK then quit DU and return to the installer. Proceed with reinstalling OS X. Note that the Snow Leopard installer will not erase your drive or disturb your files. After installing a fresh copy of OS X the installer will move your Home folder, third-party applications, support items, and network preferences into the newly installed system.
Download and install Mac OS X 10.6.8 Update Combo v1.1.
Reinstalling Lion/Mountain Lion Without Erasing the 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.
Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the main menu. Repair the Hard Drive and Permissions as follows.
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu.
Reinstall Lion/Mountain Lion: Select Reinstall Lion/Mountain Lion and click on the Continue button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless. -
Mac book pro start up, white screen pops up and it don't process any further! Can anyone help?
When my laptop was updating the software it was stuck on installing the updates. I held the power button then turned the laptop back on! It makes the on sound but stay on the white screen! Can anyone help?
Hey Antonioaok,
Welcome to the Apple Support Communities. If you are getting the white screen when you start up, there are a few steps that can be done. The first one would be resetting your NVRAM
About NVRAM and PRAM
http://support.apple.com/kb/HT1379
Resetting NVRAM / PRAM
Shut down your Mac.
Locate the following keys on the keyboard: Command (⌘), Option, P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on the computer.
Press and hold the Command-Option-P-R keys before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys.
The next step, if it does not boot to your operating system would be to attempt to boot into safe mode. These steps are also based on the fact that your profile states you are running Snow Leopard.
Mac OS X 10.6: Starting up in safe mode
http://support.apple.com/kb/PH6455
To start up in safe mode:
Shut down your computer and wait 10 seconds.
Press the power button.
Immediately after you hear the startup tone, hold down the Shift key. You should press the Shift key as soon as possible after you hear the startup tone, but not before.
Release the Shift key when you see the gray Apple logo and progress indicator (spinning gear).
To leave safe mode, restart the computer normally without holding down any keys during startup.
If after that, you were still not able to get into your operating system, the last step would be trying to reinstall the operating system.

More details about the problem : My computer is a Mid 2012 Mac Book pro 2.9GHz i7 processor with 8GB RAM updated to OS X v10.8.5
- I ran a compleet scan of my computer for any threats ( I used virus barrier express ) and there was nothing identified
- When I oppened the Activiti Monitor there are about 20-30 processes which I do not undersatand they are run under the user "root" 2 in perticular ( Kernel_task & fseventsd ) they both take up a lot of threads and kernel_task is constantly using 1.2 GB of "real memory" which is at least 20 times any other process that is running espesially the ones that run under the user "Apple" I do not know if this is causing the problems on my mac but i tryed to forces close it and it dose not even let me click the button, the others close but reopean immideatly. I will attach a screen shot of what i have mentioned here.
- The problems I am facing are mainly performance :- To state a few examples, my mac dose not seam to be able to handile even the smallest tasks like switching tabs on safari, typing any thing, playing a movie withought stopping inbetween, etc.. ( let me elaborate on why I said its not able to handil these tasks, it is because when I am trying to do any one of the afformentioned tasks inbetween the cursor becomes a rainbow collered spinning disk and I am unable to do anything for about 10 seckonds after which it starts to work again for some time before it happens again. )
- Another concern of mine is that my mac seems to be on even with the lid closed if I do not shut it down compleetly, if i just close the lid after some time the computer starts warming up, and the fan starts running. the battery is drained at the same rate or slightly less rate than it would have if i was using it normally with the lid opean. ( altough this is happning the screen dose not turn on untill the lid is opean again )
- I have only 300+ GB full out of my 750GB so i believe these are not issues caused by my mac's memory being full ( BUT THE FIRST TIME I NOTICED THIS WAS HAPPNING WAS WHEN MY MEMORY WAS ABOUT 720GB FULL WHEN THESE ISSUES FIRST AROSE I IMMEADITLY DELEATED 400+GB OF MY USELESS FILES THAT I HAD BEEN HORDING ALL OF WHICH WERE MOVIES ) that about covers it all PLEASE LET ME KNOW IF ANY ONE KNOWS WHAT TO DO.
Ps: I apoligize if I have given too many unrelevant details, not enough usefull information and or if i was just all over the place with my explanations but I am really frustrated and was hoping not to miss anyting. Please let me know if any information at all is required and ill do my best to provide it.

Mavric doesn't support my 5 years old Big Screen Display, OR? Tried to connect my Mac Book Pro after installing Mavric, The Screen didn't work as before. I could only see the Desktop but not the movies for example.
<E-mail Edited by Host>It appears what happened is the installer though it was looking at a empty drive and just went ahead and installed.
I of course am assuming here you didn't use Disk Utility to format the drive first before installing, that would wipe out your files and programs for sure.
So what to do, what to do.
Well there is hope for you as long as the drive wasn't Filevaulted.
I'll explain. When a hard drive writes data for the first time to a drive, it starts at the very top and works it's way down.
When OS X was installed the first time, it was at the top of the drive, unless you upgraded then the upgraded OS X could have been written elsewhere.
Now when you just reinstalled OS X, the new OS went on the top of the drive, overwriting any data that was there previously, so what was there you have lost forever which is about 8GB or so. If it was the previous OS there, then your more in luck because only the old OS X was overwritten.
The remaining space on the drive still can have a copy of your files, provided it's not overwritten yet.
It's because when a hard drive deletes data or reformats, it doesn't remove the data off the drive or overwrites it immediately, it's just made so it's SPACE is available for new files to be written there.
So technically one can recover the deleted data off a non-encrypted/scrubbed hard drive with special software.
The way it does this is it reads the 1's and 0's of the files themselves, and through a lot of figuring out, can tell what that file is and what it belongs too.
So what you will have to do is this:
Create a data recovery/undelete external boot drive
or if you don't have the skills, then take it to a local PC/Mac tech and they can do a direct image of the drive and then you can run Data Rescue on it to rebuild your files.
