My MacBook Pro has been having difficulties at startup. It sometimes locks and doesn't get past the white screen. It has also locked up several times and gotten a green stripes across the entire screen. What is causing this and how do I fix it?

You don't, take it to Apple for repair.
This might interest you if it's too old to fix.
My computer is not working, is my personal data lost?

My MacBook Pro will turn on and get to the login screen. After I login though it goes to a white screen.

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.

Mac OS X: Gray screen appears during startup - Apple Support

MacBook pro will not boot. I get the gray screen, an apple icon and spinning wheel. Tried to start in safe mode but get the same screen. The only thing different was that I loaded the zedge sync app yesterday. Now getting this problem.

Macbook pro will not boot. I get the gray screen, an apple icon and spinning wheel. I tried to start in safe mode, but get this same screen. The only thing different is that I added the zedge update app to do a sync for adding ringtones to my apple cell phone. How can I get a good boot. I am fairly new to apple computer.

Reset PRAM: http://support.apple.com/kb/PH4405 and then try a normal boot.
Run the Startup Manager to select Startup disk: http://support.apple.com/kb/HT1310
If those did not work your disk may be sick or dying. The top priority at this point is to make a backup copy of your data.
Check the health of the disk. Boot in Recovery Mode (Boot, Command-R). Run Disk Utility. Click on the upper left disk icon. Does the S.M.A.R.T. status say “Verified”? If not the disk/SSD is unhealthy and needs to be replaced. Even if it does not show “Verified” you can still attempt a backup.
Click on the icon indented below, usually called “Macintosh HD” and Verify Disk. If it finishes with a green “OK” message then all is well with the disk. If it shows errors in red then you have found a problem to address once the system is backed up. Do not attempt software repairs until you have secured the data.
If the disk will not show up at all in Disk Utility as your ran the tests above then it may be dead or it may have a bad internal SATA cable. A trip to an Apple store for confirmation would be in order.
If you have an external disk drive you can use as a backup drive then do so. If not Google “Hitachi USB 3.0 external hard drive 1TB” to purchase one or go to a brick-and-mortar store (including an Apple store) to pickup one. Any 1 TB external drive will do.
Assuming it is still breathing you can try to recover the data without booting from the sick disk.
Reformat the external disk. (This will erase all data on the external disk.)
Boot in Recovery Mode. Start Disk Utility. Plug in the new disk. Select it’s disk Icon (the second one down, left justified). Select the Partition tab.
Partition Layout > Single Partition
Name: Emergency Recovery 1 (or whatever name you wish to use)
Format: Mac OS Extended (journaled)
Options… > GUID Partition Table > OK
Apply
Select the Restore tab.
Drag the old system volume (Macintosh HD) to Source.
Drag the new disk volume (Emergency Recovery 1) to Destination.
Click on Restore.
It may take a long time for the backup.
If that will not complete post back for other emergency data recovery methods, including those from a brody.
If the backup succeeds, use the First Aid tab in Disk Utility to select the old volume (Macintosh HD) and Repair Disk. If it does not finish with a green OK message try to repair it once or twice more. If it repairs with a green OK message, will it boot normally? If not, boot from the Recovery Partition and reinstall OS X.
If it is still not healthy, post back for further instructions.

Why has my MacBook Pro stopped outputting audio on external speakers?

Since buying a MacBook Pro in April 2007, I had no problem playing recorded music and Internet radio on external analog speaker systems in two different houses. Suddenly this summer, the audio no longer plays through the external speakers --though it still works fine with the internal speakers. There were no major changes or accidents. The only technical issue I had was the recent malfunctioning of my laptop battery, which Apple acknowledged was defective and replaced yesterday. (I hoped that the problem might be resolved by the new battery. But it hasn't been.) Most of the discussions I've read about audio troubles with the MacBook Pro don't apply to this situation. (The most-discussed problem had to do with the internal speakers no longer working, often because the MBP's audio out port had inadvertently gone into digital audio mode.) My MacBook Pro is a 2.33 MHz Intel Core 2 Duo, OS 10.4.11, The mute button is not on. The speaker sound is up to max. And when I check the Sound status in System Preferences, the info line correctly identifies the speakers. The default ID readout is internal speakers. And the ID reads external speakers when I plug the external speakers into the headset/audio out port, But the sound plays only on the internal speakers, not on the external speakers. I miss listening to my music library and favorite NPR stations on a good sound system, where ever I go. I'd be grateful for any help. Thanks

If your computer was hot it wasn't asleep - it either didn't go to sleep or it work up after you put it to sleep. I've seen both things happen. First, read this article and follow the instructions.
1) For the next few days/weeks pay attention to the blinking light on the front of your computer when you close the lid. Don't put the computer into your backpack/case until it begins to blink. Wait a minute or so after it starts to blink to make sure it doesn't stop blinking - the signal it woke back up.
2) having followed the above instructions, if you take the computer out and it is hot again or if you take it out and discover it has powered down (you'll know this because when it starts up the battery will be drained and you'll see a progress bar over a ghostly display that will eventually become normal) immediately start the Console program and perform a search on 'sleep' and then 'wake'. This should bring up all the recent log files about sleep state changes (going to sleep and waking up). You should see one for when you put the computer to sleep and put it away and the next one should be just after you got it out. You'll find at least one though that shouldn't be there. That will tell you when the computer work up (when it shouldn't have) and might give a clue as to why.
One of the whys could be a magnet that is making the computer think the lid has been opened.

Why has my macbook pro suddenly got slower?

My macbook pro has been working perfectly fine until this morning. When i turned it on it was much slower than usual, so i force quit all applications and restarted it. It had no effect so i tried it again but it is still very slow! Can anyone give any tips as to why this might happen/how to resolve the issue?
Thanks.

First, back up all data immediately, as your boot drive might be failing.
There are a few other possible causes of generalized slow performance that you can rule out easily.
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.
Otherwise, take the steps below when you notice the slowdown.
Step 1
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 2
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.
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.

Why has my macbook pro serial number changed after getting it repaired?

I just noticed that the serial number in the 'about this mac' information has a different serial number to what is on the back of the macbook pro, which is the same serial number on my apple care/phone . I had a lot of issues with my macbook pro it was sent to repair in july 2013 then in august 2013. Why has the serial number changed? I tried using my original serial number to use the online apple care service however it did not recgonice my serial number when I tried the new serial number it regconised it but said I did not have apple care but I do. I don't know what the apple team have done to my macbook as it requires to go in for repair again.

Was it repaired at Apple or an authorized service provider?
You need to contact the repair place/store and/or call Apple and make them aware of the problem - sooner rather than later. Make sure you give them the repair/case number so they can find the paperwork for it.
I had a logic board replaced and the tech also did not do anything - I called Apple and the tech came back to my house to take care of it. It's important because you want to make sure that your Applecare is being associated with the right serial number.

Why has my macbook pro been running slow?

Why is my Macbook Pro Running So Slow. I have the i7 2.8 GHz. I Have the Late 2011 version. I Have 4GB Of Ram. Help!

I have a 2.8 GHz Macbook Pro with 4GB of Ram and also it's the Late 2011 version. It's also a i7. ALSO IT HAS 750GB, Why is my Mac Running SLOW!!!!!!!!

Frankly, I was dissapointed when I got my MBP last year. Moving from a single core, windows laptop with 2GB of Ram and an IDE HD, I expected better performance from my new 2.2Ghz i7 quad core, 4GB RAM MBP. I got the hi-res antiglare upgrade because more screen real estate is always good. I do a bit of multimedia work so I upgraded the HD as well to the 750GB 7200 RPM option.
I fired up my new mac, downloaded updates, loaded up my software and was off to fresh new beginnings. During the first week I started seeing the "spinning umbrella" Even during simple tasks. With only a few apps open the system was sluggish. Even the dock would jitter. Being a bit tech savy I opened up the activity monitor and saw that the system was running low on RAM. Who would have thought that 4GB of RAM would not be enough? My previous machine had 2GB of RAM and did the same tasks quite reasonably. Anyone would have concluded that a machine with double that would perform better. Aparrently not. At least not this MBP. I was so upset because I just spent about 2000 USD for the "best laptop we've build to date" WITH UPGRADES! and I'm going to have to spend more to upgrade the RAM.
Anyway I upgraded to 8GB of RAM and runs reall really smooth now.
My suggestion if your MBP is running slow, is to upgrade your RAM to 8GB or more. Check out the guys at Other World Computing, they have lots of upgrades for macs.
Here is a link http://eshop.macsales.com/shop/memory/Apple_MacBook_MacBook_Pro/Upgrade
The hard truth cut through all the marketing and hit me. I'll say it this way; a computer is a computer, is a computer. Forget all the hype. With the same specs, a mac gives just sbout the same performance as a PC. That said, I really love my MBP(now that I have 8GB of RAM). This mac gives me the best computing experience I have ever had. Apple really shines in their User interface and user experience. I really love the gestures and hot corners, and mission control. I usually have a lot of apps open the same time, so those features really help in switching between my apps.
I'm going to further upgrade my RAM to 16GB and upgrade the HDD to an SSD pretty soon. I want my machine to be really snappy.
I hope this was helpful.

Back up all data before proceeding.
This procedure will unlock all your user files (not system files) and reset their ownership, permissions, and access controls to the default. If you've intentionally set special values for those attributes on any of your files, they will be reverted. In that case, either stop here, or be prepared to recreate the settings if necessary. Do so only after verifying that those settings didn't cause the problem. If none of this is meaningful to you, you don't need to worry about it, but you do need to follow the instructions below.
Step 1
If you have more than one user, and the one in question is not an administrator, then go to Step 2.
Triple-click anywhere in the following line on this page to select it:

MacBook Pro 17" (mid 2010) desktop does not fill entire screen

Hi,
First of all I apologize for posting such a long question but in order to best describe the problem I am having with my MacBook Pro, I had to mention every detail.
I recently installed windows 7 x64 home premium on my new MacBook Pro 17 inch (mid 2010). After successfully installing the Bootcamp drivers (version 3.1) I have noticed that my screen resolution has become slightly smaller than before. There are half an inch thick black bars on the right side as well as on the top of the screen.
This problem is not limited to windows, I'm having the same problem in mac osx after the windows 7 installation. Even on the start up gray screen.
I have tried almost every trick in the book, adjusting the screen resolution from the display settings menu (which by the way are on 1920x1080), checking all the settings on the nvidia control panel, resetting the SMC, resetting the VRAM, running the hardware diagnostic test (short as well as the long one), formatting the windows partition, formatting the Mac OSX partition then performing a fresh install of both. So far, I have been frustrated with failure.
After trying my best to resolve this issue on my own, I tried my luck with apple support. The customer representative was very helpful and listened carefully as I explained the problem to him. He asked me first to check for any available updates on my mac osx as well as in win 7. I told him that I had already installed every available update in both the OS's. He then asked me to reset the SMC and after that to reset the VRAM. Even though I had already tried this, I still gave it another shot but that didn't help.
Since my MBP was still under the standard warranty, (I have also purchased the Apple Care Protection Plan) he asked me to take it to an Apple Authorized Service Provider. I took his advice and went to the nearest AASP. The Apple Engineer over there performed the same steps, adjusting screen resolution, resetting SMC and VRAM, but even he was not able to resolve this problem. He suggested that I should get my graphics card replaced or if required upon inspection, the logic board replaced. To be very honest, I was very skeptical about his suggestion as the laptop is brand new, hardly 2 months old. How is it possible that there could be a problem with the hardware? I asked him whether it is possible to restore the firmware of the graphics card as the problem could be software related. He said that Apple have not started issuing firmware restoration CD's for the latest mid 2010 MBP's so a firmware restore won't be possible. My best bet would be to get the graphics card replaced or the whole logic board replaced.
So you see, I have been down almost every possible road which could have lead to resolving this issue but unfortunately I am stuck with it. I hope any of you could offer a different approach in order to get rid of this annoying problem.
Any help would be highly appreciated. (Trust ME!!!)
PS: I have also posted this question on the Bootcamp forums page. Since the problem is not limited to windows 7, I decided to post here as well.

UPDATE: I just came back after a visit to the apple service provider here in New Delhi. They have replaced the logic board on my macbook pro and guess what? the situation is still the same. No difference what so ever as far as the screen resolution is concerned. I can still see those black bars in the exact same places i.e. the right hand side as well as on the top of the screen. Even the size of the black bars are still the same.
I am so upset right now. After trying my best in order to solve this problem I went to the AASP with high hopes. I was very confident that after replacing the logic board this annoying problem would go away but unfortunately that's not the case. Even the Apple Engineer was clueless on how to solve this problem.
I think I'll call apple care and speak to the customer relations regarding a replacement.
If any of you can come up with a solution to this problem please let me know.
I'm all ears!!!

MacBook pro doesnt turn on it straus in the white screen with the apple and a circle and themes turns off it starter web i put ultimate lion x version

My computer MacBook pro want turn on it started when input the lion ultimate versión it straus in the white screen with the Apple and the circle ten it goes off

Try starting your computer by holding down the command + R keys, then run disk utility on your hard drive to verify/repair it. Take a look at his link, http://support.apple.com/kb/HT1782

Why has my MacBook Pro stopped saving state to disk when battery runs out?

In the past, when my battery was running low, I could carry on working safe in the knowledge that the system state would be saved just before the power completely failed. When power was restored, the saved state was restored and I could carry on.
Now it seems to just die and then I'm left to the mercy of any app-based autosave.
What's changed?!!

Doubt your cpu needs any thermal grease... Upgraded my MBP (early 2010) to ML when it first came out, prior to this everything was working flawlessly and I mean one couldn't ask for anything more... After the upgrade it was total garbage with big time overheating, program crashes and a problem where it refused to come out of a deep sleep without a forced shutdown. One thing I never really looked into was how it affected the battery life but one can only assume it took a toll on it as well.
Needles to say I downgraded back to the originally installed OS X ASAP, thankfully we regained our original stability and sanity to boot with no ill affects on the battery. Have read countless posts about these problems and as of yet have not found a resolve to my issues, too gun shy after the experience to even think of giving it another whirl... Lost confident's in Apples ability to get it right as this was downright deplorable in my opinion.
Sorry if this wasn't much help but from reading your post you say "after upgrading" which sounds to me like all was fine prior to switching to ML, no point in tearing apart anything if that is not need.

What is application memory and why does my macbook pro keep running out of it?

what is application memory and why does my macbook pro keep running out of it?

There is excessive swapping of data between physical memory (that is, the memory chips on the logic board) and virtual memory (one or more files on the startup volume.) That activity is relatively slow and causes the whole system to be less responsive. It can happen for two reasons:
          A long-running process with a memory leak (a kind of bug)
          Not enough memory for your usage pattern
Please note that if the cause is a memory leak, installing more memory will not help. That's likely if you already have more than 4 GB of memory. Tracking down a memory leak can be difficult, and it may come down to a process of elimination.
These instructions are for OS X 10.9 and later. Some details may be slightly different for earlier versions of OS X.
When you notice the swap activity, open the Activity Monitor application and select All Processes from the View menu, if it's not already selected. Select the Memory tab. Click the heading of the Real Mem column in the process table twice to sort the table with the highest value at the top. If you don't see that column, select
          View ▹ Columns ▹ Real Memory
from the menu bar.
If one process (excluding "kernel_task") is using much more memory than all the others, that could be an indication of a leak. A better indication would be a process that continually grabs more and more real memory over time without ever releasing it. Here is an example of how it's done.
The processes named "Safari Web Content" render web pages for Safari. They use a lot of memory and may leak if certain Safari extensions or third-party web plugins are installed. Consider them prime suspects.
Another process often implicated in memory leaks is "inkjet4" or "inkjet8," which is a component of the HP printing software. If it's present, force-quit the process in Activity Monitor to solve the problem temporarily. Empty the print queues in the Printers & Scanners preference pane (which has a slightly different name in each recent version of OS X.) If you don't use an HP printer, reset the printing system. Otherwise, if the problem is recurrent, update the software (which may not help) or contact HP support.
"Wired" memory should be a small part of the total. That memory is not swapped, but it makes less physical memory available which may then result in swapping. If you have a lot of wired memory, that's usually an indication of a memory leak in a third-party program that modifies the operating system at a low level. Ask for guidance in that case.
If you don't have an obvious memory leak, your options are to install more memory (if possible) or to run fewer programs simultaneously.
The next suggestion is only for users familiar with the shell. For a more precise, but potentially misleading, test, run the following command:
sudo leaks -nocontext -nostacks process | grep total
where process is the name of a process you suspect of leaking memory. Almost every process will leak some memory; the question is how much, and especially how much the leak increases with time. I can’t be more specific. See the leaks(1) man page and the Apple developer documentation for details.
