Macbook Pro 13in retina will not start up, but backlight turns on.

After using it last night, I woke up this morning and my mac was what i thought to be off. But I realized that the back-light was on and nothing else. Now when I try to turn it on the back-light and apple logo come on but there's no start-up sound and when I close the lid they don't turn off. Just fyi I'm running the Yosemite public beta as well but I don't think this is the problem. Cant get anything other than this with multiple restarts. Anyone know something I can do to fix it? Thank you.

My 13 inch Macbook pro w retina will not install/download OS X Mavericks because it says I do not have the requirements in order to install it. I purchased my Mac this past month on 11/20/13 so i do not have a problem with it being an older version. Please help. This is my first computer so i dont have any experience on how to fix this.

You can't install the App Store version of Mavericks because your model needs a special version. If you ever need to reinstall it, boot into Recovery.

MacBook Pro 15 inch Will Not Start

If I shut down or attempt a restart on my MBP 15 inch (Tiger) it will not start or restart. Instead I hear a whirring sound and then the oval light comes on and remains on as a solid light bu the screen is dark. If I wait several hours or overnight it usually will then start or restart.
Apple Care says send it off to them for ten days but is there an easier solution? Thanks for any advice.

check the battery info.. >about this mac>more info>system report and select "power" on the lefthand column. How many cycles? What does it say about the condition? etc.

MacBook Pro 13" Retina will not reboot in Yosemite

I have a brand new -- the newest model -- MacBook Pro 13 in. Retina that was doing well with Mavericks. After having Yosemite installed it froze up when the top was closed, and now it will not reboot.
I tried holding the power button down for several seconds and then pressing the power button again, just long enough to get the start-up gong. Tried this three or four times. Each time the reboot stops when the progress bar on the screen, under the Apple logo, reaches just less than half way. Then nothing. Letting the machine sit for long periods while it works out its own problems does not help. No progress toward rebooting.
I have tried rebooting with and without the power cable attached.

Take each of these steps that you haven't already tried. Stop when the problem is resolved.
To restart an unresponsive computer, 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.
Step 1
The first step in dealing with a startup failure is to secure the 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 the last backup, you can skip this step.
There are several ways to back up a Mac that is unable to start. You need an external hard drive to hold the backup data.
a. Start up from 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.” The article refers to starting up from a DVD, but the procedure in Recovery mode is the same. You don't need a DVD if you're running OS X 10.7 or later.
b. If Step 1a fails because of disk errors, and no other Mac is available, then you may be able to salvage some of your files by copying them in the Finder. If you already have an external drive with OS X installed, start up from it. Otherwise, if you have Internet access, follow the instructions on this page to prepare the external drive and install OS X on it. You'll use the Recovery installer, rather than downloading it from the App Store.
c. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, start 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.
d. 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
If the startup process stops at a blank gray screen with no Apple logo or spinning "daisy wheel," then the startup volume may be full. If you had previously seen warnings of low disk space, this is almost certainly the case. You might be able to start up in safe mode even though you can't start up normally. Otherwise, start up from an external drive, or else use the technique in Step 1b, 1c, or 1d to mount the internal drive and delete some files. According to Apple documentation, you need at least 9 GB of available space on the startup volume (as shown in the Finder Info window) for normal operation.
Step 3
Sometimes a startup failure can be resolved by resetting the NVRAM.
Step 4
If a desktop Mac hangs at a plain gray screen with a movable cursor, the keyboard may not be recognized. Press and hold the button on the side of an Apple wireless keyboard to make it discoverable. If need be, replace or recharge the batteries. If you're using a USB keyboard connected to a hub, connect it to a built-in port.
Step 5
If there's a built-in optical drive, a disc may be stuck in it. Follow these instructions to eject it.
Step 6
Press and hold the power button until the power shuts off. Disconnect all wired peripherals except those needed to start up, and remove all aftermarket expansion cards. Use a different keyboard and/or mouse, if those devices are wired. If you can start up 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.
Step 7
If you've started from an external storage device, make sure that the internal startup volume is selected in the Startup Disk pane of System Preferences.
Start up in safe mode. Note: If FileVault is enabled in OS X 10.9 or earlier, or if a firmware password is set, or if the startup volume is a software RAID, you can’t do this. Post for further instructions.
Safe mode is much slower to start 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 the login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
When you start up 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, the startup volume is corrupt and the drive is probably malfunctioning. In that case, go to Step 11. If you ever have another problem with the drive, replace it immediately.
If you can start and log in in safe mode, empty the Trash, and then open the Finder Info window on the startup 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 restart as usual (i.e., not in safe mode.)
If the startup process hangs again, the problem is likely caused by a third-party system modification that you installed. Post for further instructions.
Step 8
Launch Disk Utility in Recovery mode (see Step 1.) Select the 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 restart as usual.
Step 9
If the startup device is an aftermarket SSD, it may need a firmware update and/or a forced "garbage collection." Instructions for doing this with a Crucial-branded SSD were posted here. Some of those instructions may apply to other brands of SSD, but you should check with the vendor's tech support.
Step 10
Reinstall the OS. If the Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
Step 11
Do as in Step 9, but this time erase the startup volume in Disk Utility before installing. The system should automatically restart into the Setup Assistant. Follow the prompts to transfer the data from a Time Machine or other backup.
Step 12
This step applies only to models that have a logic-board ("PRAM") battery: all Mac Pro's and some others (not current models.) Both desktop and portable Macs used to have such a battery. The logic-board battery, if there is one, is separate from the main battery of a portable. A dead logic-board battery can cause a startup failure. Typically the failure will be preceded by loss of the settings for the startup disk and system clock. See the user manual for replacement instructions. You may have to take the machine to a service provider to have the battery replaced.
Step 13
If you get this far, you're probably dealing with a hardware fault. Make a "Genius" appointment at an Apple Store, or go to another authorized service provider.

Macbook pro 2.4 will not start up. Blank screen!

My Macbook pro just quit the other day. Blank screen and I don't get the bong at start up. I moved the ram around and it bonged once but I can't repeat it. Pulled hard drive to get info off and replaced with new one since it was from July 07. Could zap PRAM with bong but no change.

Hi Lisa,
Try the following:
Boot from install disc (insert disc > restart > immediately hold down the c key and keep holding it until you see “Preparing Installation”) > at first screen select the language and click Continue > click on the Utilities Menu in the menu bar > select Disk Utility > select your HD in the panel on the left side (the name of the HD’s manufacturer and the model number, usually the top item in the list) > look at the bottom of the main window next to S.M.A.R.T. status and see if it says “Verified” (good) or something more ominous like “Failing.”
If S.M.A.R.T. status is "Verified," run Repair Disk > click Repair Disk at bottom of main window. Run this at least twice, and keep running it until it says “appears ok” twice in a row. If that doesn’t happen, you may need a stronger utility (such as DriveGenius, TechToolPro, DiskWarrior) or if the directory is damaged beyond repair, you may need to reinstall the OS, or you may have a damaged HD which will need to be replaced (repair utilities can only repair the directory structure, not the HD itself). When this is finished, quit Disk Utility, quit the installer, and restart. Once booted normally, go to Applications > Utilities > Disk Utility and run Repair Permissions.

MacBook Pro, late 2013 will not start up on battery.

Why won't my MacBook Pro (Retina, 13", late 2013) start up on battery, even though it's charged 100%? I can start it up with the power cord, then disconnect the cord and it runs fine and the battery doesn't seem to run down too quickly. I just downloaded OS X Yosemite 10.10.3 last night and this started today. Any help?

I have a MacBook Pro 15" and my warranty just ran out! I partitioned my harddrive into two partitions, one with Snow Leopard and the other with microsoft.This morning I turned on my Macbook Pro and it will not boot into Snow Leopard.

Good Morning,
I have a MacBook Pro 15" and my warranty just ran out! I partitioned my harddrive into two partitions, one with Snow Leopard and the other with microsoft.This morning I turned on my Macbook Pro and it will not boot into Snow Leopard. I shut it off took out the battery, reinstalled the battery. Then I put in the Snow Leopard CD and booted up to disk utility and The Snow Leopard partion would not show up?? I do see the microsoft partion.
I also rebooted holding down the shift key and still no Snow Leopard
Could you please tell me what I can do, what keys do I press on restart any advice to get Snow leopard back.
thank you.

Have you restarted holding down the Opt key? That procedure should give you a gray screen with all of the partitions that exist. Then select the SL partition for boot. Also go to System Preferences and Startup Disk, unlock the lock and select the SL partition as the default boot partition, then relock.

My macbook pro running lion will not boot . it stays on the grey page with the cog spinning. I have tried all methods of booting to no avail. I have removed the bottom and taken out the battery and the ram . will this affect my applecare warranty.

there was a recent software update that seemed to screw HDV up. Do some searching here over the last month or 2 and you'll find a bunch of posts and some possible solutions.
Worst case scenario, do as Shane suggests. But might I suggest you take a look at the user tips section of the forum. there are some great tips on how to prevent these sorts of problems by cloning your startup drive, etc.

Just the Option key. Third from the left on the bottom row.
If that does not work, try the more elaborate steps described here:

MacBook Pro 13in(Retina)with only 8G

I recently purchased a MacBook Pro 13in(Retina)with only 8G-any recommendations of how to get more memory? (I can't even load a basic desktop pub. program like Printshop)

I think you're confusing RAM with storage. Even the base model MBPr has 128GB of flash storage. The 8gb of ram is temporary storage that your mac uses for the operating system and applications. What exactly do you mean that you can't load even basic programs?

You have to take the computer to the Apple store.

You could try updating your apple TV and then restarting it. Bit of a guess.

I have a 2007 Macbook, so it's probably a lot older than your Macbook Pro, but it sounds like what happened to me, except that mine hadn't travelled anywhere. I pulled out the ram and blew out some dust, popped them back in, and wha-la! it turned back on and worked better than ever! Or otherwise you've got a dud/old/warped/fried battery, which is also what happened to my laptop - it got so bad it did what your laptop is doing. Ordered a new battery online and all good since then. Or otherwise, like the previous post asked, 'is it plugged in?'

Go to System Preferences>Accounts and then select your account, then startup items, remove Word from the list and reboot, you should be fine then.
