My 3 year old macbook pro shuts off when it is trying to turn on

when i turn on my macbook, it makes the startup sound, the logo comes. but then a loading bar appers and it starts loading, when it's about 1/5 of the way the loading bar dissapears and it shuts down about 5 seconds after. the software it's using is mavericks (10.9.1)

TheMikkelfl1,
boot your MacBook Pro into Recovery mode by holding down a Command key and the R key as it starts up. Once the 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 get to the login screen now?

Macbook Pro shutting off when closed - Mountain Lion

Just upgraded to Mountain Lion and now my macbook pro shuts off instead of sleeps everytime i close the screen and needs to be re-booted when screen is re-opened. Any one had the same issue and any known fixes?

Check System Preferences --> Energy Saver and make sure you do not have the sleep sliders set to "Never".
This may pertain to either or both Battery and/or Power Adapter tabs in System Preferences.

MacBook Pro shuts off when unplugged.

For the past week my MacBook charger has been not functioning correctly. It only charged my computer when it was the the right position. I figured there was a short in the wires and was just going to pick up a new one. Last night however, the charger stopped working completely. I tried moving it around for about an hour until i just gave up and figured there was no hope. As soon as i shut the MacBook though, the charger light came on, but again when i moved the wire too much, it turned off. As soon as the charger light turned off, so did my MacBook. And i thought it was weird since there was still about 20% battery life, and it turned back on fine, but the date got reset to the year 2000 and it made me put in my wifi info again, which has never happened. I shrugged it off and really didnt think much of it though until it happened again today. This afternoon i plugged my Macbook in and it was and the charger was working fine after i found the right position to put it in. I let it charge for a few hours while i was out, and when i got home i used my Macbook for about two hours before i decided to move the Mac, causing my charger to move and stop working. And my MacBook imediately shut off again, exactly how it did the night before. What is causing my Mac to do this? How do i fix it? Its about 2 years old and this is the first time anything like this has happened to it! Please help me, I'm not good with computers at all so i have no idea what to do. By the way i dont think its the battery since when i turn it back on it runs just fine without being plugged in. It only turns off when it has been charging and then stops.

Borrow a friend's MagSafe Charger or try with the ones in the Apple Store. Sorry I wasn't clear from your post if you purchased a new charger yet.
Also clean the contacts on the MagSafe port and the charger side.
Apple recommends:
"Remove debris gently with a cotton swab or a soft bristle toothbrush, which provide the strength, flexibility, and precision for this task. Be careful not to get any cotton fibers stuck in the pin receptacle. You may use isopropyl alcohol to aid in cleaning the connectors as well. Be sure the connectors are dry before using the computer or adapter after cleaning."

Why does my MacBook Pro shut off when I close it?

When I am done using my MacBook Pro I would usually just shut the lid and the MacBook would then go into sleep mode. In other words later when I pick it up and open it the MacBook screen will light and I can begin using it immediately. However, lately when I shut the lid the MacBook will shut off completely and I will need to push the power button to turn it on again. I am curious as to what may be causing this? Any help or knowledge on this would be greatly appreciated! Thanks.

Reset your SMC, as described here:

Early 2011 Macbook Pro shuts off when charger unplugged. Worked fine yesterday.

Hi,
I have an early 2011 Macbook Pro, which I purchased brand new; it's just over one year old. Yesterday the laptop held a charge no problem for 6 hours or more. Today, when I disconnect it from the charger it goes to sleep. When I plug it back in and press the power button it wakes up, and I can use it.
This cannot be a battery issue, since it was holding a charge without trouble yesterday. Does this appear to be a serious issue? My one year warranty expired 2 months ago yesterday, and I had forgot to purchase AppleCare. Sigh. It almost seems like surgically-planned obsolecense or punishment for not purchasing AppleCare.
I would immensely appreciate any help/suggestions on this.
Thanks.

OK, in that case:
Reinstall OS X without erasing the drive
Do the following:
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 the Mac OS X 10.6.8 Update Combo v1.1.
Upgrading to Lion or Mountain Lion will not solve the problem.

Macbook Pro shutting off when unplugged and at 80% battery? help!

I have an early 2011 MacBook Pro 15 in. that i got in May of 2011. When i unplug the power adapter it works fine, but at about 80% battery it shuts off. i go to turn it back on and it acts as if it is dead, i press the power button again and it turns on without problem (although the date and time at first is messed up). What is wrong? I recently had to get my hard drive replaced 2 months ago and it has been working fine until yesterday. What could be wrong and how do i fix it?

Make a "Genius" appointment at an Apple Store to have the machine tested. Back up all data before you go.

My MacBook Pro shuts off when it's unplugged

My MacBook Pro keeps on shutting off after about a minute or two being unplugged. It works fine while it is connected to the power source but I can't figure out what is going on. Recently it shut off and when I turned it back on, it lost my network preferences and asked me about allowing mDNSresponder and other permissions. If anyone can help it would be greatly appreciated.

You sound like you have a defective battery or a corrupt calibration file or a corrupt SMC data. Do the following:
MacBook Air and MacBook Pro (Late 2008 and later)
1. If the computer is on, turn it off by choosing Shutdown from the Apple () menu.
2. Connect the power adapter to a working power source.
3. On the built-in keyboard, press (left) Shift-Control-Option along with the power button once.
4. Wait 5 seconds and press the power button to start the computer.
Note: You must use the keys on the left side of the keyboard.
If this changes things you may also want to recalibrate the battery
(major Deja Vu here)
Go to the Help menubar item in the Finder to learn how to calibrate the battery. It is a procedure that must be done a very specific way or it will not work at all. Print it out or write it down before proceeding.

I currently have a one year old MacBook Pro, and right when I boot up the system, the kernel_task is using about 1GB of the 4GB of RAM that I have. Is this normal? Or if not, how can I reduce the kernel_task?

I have noticed that my computer is running super slow, even when I only have one application (like Chrome) running for a short amount of time.

First, back up all data immediately, as your boot drive might be failing.
Step 1
This diagnostic procedure will query the system log for messages that may indicate a hardware fault. It changes nothing, and therefore will not, in itself, solve your problem.
If you have more than one user account, these instructions must be carried out as an administrator. I've tested them only with the Safari web browser. If you use another browser, they may not work as described.
Triple-click anywhere in the line below on this page to select it:
syslog -k Sender kernel -k Message CReq 'Channel t|GPU D|I/O|nspace-h|n Cause: -' | tail | open -ef
Copy the selected text to the Clipboard (command-C).
Launch the Terminal 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 Terminal in the icon grid.
Paste into the Terminal window (command-V).
The command may take a noticeable amount of time to run. Wait for a new line ending in a dollar sign (“$”) to appear.
A TextEdit window will open with the output of the command. Normally the command will produce no output, and the window will be empty. If the TextEdit window (not the Terminal window) has anything in it, stop here and post it — the text, please, not a screenshot. The title of the TextEdit window doesn't matter, and you don't need to post that.
Step 2
There are a few other possible causes of generalized slow performance that you can rule out easily.
Reset the System Management Controller.
If you have many image or video files on the Desktop with preview icons, move them to another folder.
If applicable, uncheck all boxes in the iCloud preference pane.
Disconnect all non-essential wired peripherals and remove aftermarket expansion cards, if any.
Check your keychains in Keychain Access for excessively duplicated items.
Boot into Recovery mode, launch Disk Utility, and run Repair Disk.
If you're booting from an aftermarket SSD, see whether there's a firmware update for it.
If you have a MacBook Pro with dual graphics, disable automatic graphics switching in the Energy Saverpreference pane for better performance at the cost of shorter battery life.
Step 3
When you notice the problem, launch the Activity Monitor 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 Activity Monitor in the icon grid.
Select the CPU tab of the Activity Monitor window.
Select All Processes from the menu in the toolbar, if not already selected.
Click the heading of the % CPU column in the process table to sort the entries by CPU usage. You may have to click it twice to get the highest value at the top. What is it, and what is the process? Also post the values for % User, % System, and % Idle at the bottom of the window.
Select the System Memory tab. What values are shown in the bottom part of the window for Page outs and Swap used?
Next, select the Disk Activity tab. Post the approximate values shown for Reads in/sec and Writes out/sec (not Reads in and Writes out.)
Step 4
If you have more than one user account, you must be logged in as an administrator to carry out this step.
Launch the Console application in the same way you launched Activity Monitor. Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left. If you don't see that menu, select
View ▹ Show Log List
from the menu bar.
Select the 50 or so most recent entries in the log. Copy them to the Clipboard (command-C). Paste into a reply to this message (command-V). You're looking for entries at the end of the log, not at the beginning.
When posting a log extract, be selective. Don't post more than is requested.
Please do not indiscriminately dump thousands of lines from the log into this discussion.
Important: Some personal information, such as your name, may appear in the log. Anonymize before posting. That should be easy to do if your extract is not too long.

Issues With MacBook Pro Shutting Off

I have been having troubles the past couple of days with my MacBook Pro shutting off when running on battery power.
MacBook Pro OSX 10.4.11. 2.16 Intel Core Duo. 1 G Ram.
I will have plenty of battery charge and then "poof", computer just goes black and has no power. It does turn back on, but gets annoying. Everything runs fine when plugged into the wall.
Anyone have any ideas of what may be causing this?
Thanks.

How old is your machine? This sort of thing is covered under warranty (or apple car). I got a new one about a year ago that way. Apple WILL ask for number of charge cycles. Believe it or not, high numbers can be good because it says that you have actually been using the battery and it's not just dead from sitting unused.
It sounds like you have a dead cell. Your battery is separated into several compartments. Your charge looks fine until that cell is actually needed. At that point, CLUNK. Nothing works.

My 1-year old MacBook Pro Retina shuts itself without giving a warning when the battery is at 5-15% of capacity. Idk what to do about it.

KarnPS,
start recharging your battery when it gets down to 20% — you’ll shorten your battery’s lifespan by running on battery power beyond that.

I killed my computer with coffee. It's out of waranty and applecare has run out. It's a 4 year old Macbook Pro. Any idea whether it makes sense to try and fix it?

I killed my computer with coffee. It's out of waranty and applecare has run out. It's a 4 year old Macbook Pro. Any idea whether it makes sense to try and fix it?

Nothing works at all. When I spilled the coffee I shut it down, unplugged everything, turned it over and put paper towels beneath it to drain. Made the mistake of turning it back on after a couple of hours. It worked but emitted strange noises from the internal speakers. Turned it back off, but have not been able to turn it back on since. I disassembled the entire macbook yesterday, found coffee stains on the keyboard components. Tried to turn it on and get nothing. The only sign of life is the battery indicator. When I press the button the series of green lights come on, but that's it. Thanks for your responses. Jaylloyd

I just tried to wake up my 4 year-old MacBook Pro after perhaps an hour of inactivity, and it just 'pinwheels' and won't restart. HELP!!!!!!!!!
Semi-experienced user - Western New York.
System was operating nominally until I opened it from 'sleep' mode after ~1 hour of inactivity.
No idea what's going on. I had just installed a Flash Player update [not an atypical occurrence] at ~6:00 PM this evening, but used the system without incident after that. Re-Start attempt does not appear to succeed, the circular pre-OS icon never clears and displays the authorization screen.
Anyone with an idea how to help would be greatly appreciated. We have so much personal and business data on this machine!!!
Thanks!
Jim F.

Press and hold the power button for a few seconds until the power shuts off, then release, wait a few more seconds, and press it again briefly to restart.
The fact that you're worried about the data implies that you have no backups, or that you don't have confidence in your backups. Your first priority must be to back up all the data you intend to keep. Ask if you need guidance.

I have a 2 year old MacBook Pro and the superdrive has stopped working, it won't take discs in as if there is one already inside but iTunes or the dvd player doesn't recognise that there is a disc inside and if there is it can't be ejected

I have a 2 year old MacBook Pro and the superdrive has stopped working, it won't take discs in as if there is one already inside but iTunes or the dvd player doesn't recognise that there is a disc inside and if there is it can't be ejected, i have tried shutting down and restartinf while holding down the trackpad, as recommended on some forums but that has done nothing
It might be a huge coincidence but the drive was working fine before i installed lion?

Installing Lion would not cause the superdrive to stop working. Are you unsure as to whether or no a cd/dvd is inside? Something may be broken inside and you should consider bringing it in for service.

I am running OS X Yosemite on my four year old MacBook Pro which has become progressively slower and is loaded with applications I no longer use. I plan to start afresh by formatting a new 1TB SSD as a boot disk and reinstalling Lightroom 5 and PhotoShop CC.
Is there a list of the files and/or folders that contain Settings and Preferences which can be copied from the old system to the new?

with your cc apps you should try to use the sync feature. that's never worked consistently for me, but when it does work, it's helpful.
there are preference folders and presets and settings that you could copy but you're better off installing fresh because a common problem for people with adobe program issues is a settings issue.

I have a 3 year old MacBook Pro with MAC OSX 10.6.8, iPhoto '09 version 8.1.2 and have downloaded two software programs: one is Aperture 3.2 and the other is Photoshop Elements 9 (which I got from a friend who didn't need it). I am totally happy with the

I have a 3 year old MacBook Pro with MAC OSX 10.6.8, iPhoto ’09 version 8.1.2 and have downloaded two software programs: one is Aperture 3.2 and the other is Photoshop Elements 9 (which I got from a friend who didn’t need it).
I am totally happy with the way iPhoto organizes my photos and how I can work with iMovie to create slide shows with music from iTunes, etc.
I have been shooting mostly high resolution jpegs and I continue to learn more and more about photography, post processing etc. I realize that the small adjustments I can make in iPhoto are good, and are adequate most of the time. However, a have started to experiment with shooting RAW images and would like to go the next step, ie. post processing.I am totally technically challenged and need SIMPLE, INTUITIVE programs and am certainly NOT anywhere ready for Photoshop CS whatever!
After having these programs sit on my computer, I decided to try to see if I could figure them out. When I opened Aperture, this is what first comes up.
“Welcome to Aperture 3.2
Your library needs to be upgraded to work with this version of Aperture. Once upgraded, you will not be able to use this library with previous versions of Aperture.
Upgrading a library from previous versions of Aperture 3 generally takes a few minutes or less, though larger libraries will take longer. After that, Aperture 3.2 will upgrade your library's thumbnails, but you can use the application during that time.
Tip: To open a different library, quit Aperture and hold the Option key down while starting Aperture
Current Library Location:
Jadzia (home) -----Pictures------Aperture Library
QUIT UPGRADE”
I have heard horror stories about moving your entire library to Aperture, ending up with 2 libraries, etc. etc. hence my previous reluctance in attempting Aperture. In addition, many of my photography friends are saying: Go with Lightroom 3.....you’ll love it!
So here is my dilemma. I don’t want to mess around with my iPhoto library. All I want to be able to do, is to isolate a few photos, export them to Aperture, Elements, and work on them there, then bring them back into iPhoto.
Can I do this? Should I forget about Aperture and Elements and look at purchasing yet another program like Lightroom?

Export those few photos via the File ➙ Export ➙ File Export menu option with Kind = Original to the Desktop. Then import them into the Aperture library. That would keep one copy in your iPhoto library and another in your Aperture library to edit, etc.
You can use Photoshop Elements 9 from within iPhoto as your editor of choice. However, if you edit a raw file in iPhoto with PSE9 the resulting edited version must be saved outside the iPhoto Library and imported back in as a new file. For editing jpegs just do a Save (not a Save As) and it all will be kept within iPhoto.
Using Photoshop or Photoshop Elements as Your Editor of Choice in iPhoto.
1 - select Photoshop or Photoshop Elememts as your editor of choice in iPhoto's General Preference Section's under the "Edit photo:" menu.
2 - double click on the thumbnail in iPhoto to open it in Photoshop. When you're finished editing click on the Save button. If you immediately get the JPEG Options window make your selection (Baseline standard seems to be the most compatible jpeg format) and click on the OK button. Your done.
3 - however, if you get the navigation window
that indicates that PS wants to save it as a PS formatted file. You'll need to either select JPEG from the menu and save (top image) or click on the desktop in the Navigation window (bottom image) and save it to the desktop for importing as a new photo.
This method will let iPhoto know that the photo has been editied and will update the thumbnail file to reflect the edit..
NOTE: With Photoshop Elements the Saving File preferences should be configured as shown:
I also suggest the Maximize PSD File Compatabilty be set to Always. In PSE’s General preference pane set the Color Picker to Apple as shown:
Note: to switch between iPhoto and PS or PSE as the editor of choice Control (right)-click on the thumbnail and select either Edit in iPhoto or Edit in External Editor from the contextual menu. If you use iPhoto to edit more than PSE re-select iPhoto in the iPhoto General preference pane. Then iPhoto will be the default editor and you can use the contextual menu to select PSE for your editor when desired.
