MacBook Pro checkered screen? Won't start up??

Yesterday I was using my MacBook Pro and then all of a sudden the screen randomly got covered in this checkered pattern and it was flickering so I shut off the computer and now it won't start up it goes to the gray apple screen and the icon will spin for about 40 seconds then stop and it stays like that. There is a little checkering over the gray apple screen to. I've tried starting up in safe mode, resetting prvm, holding option and s, none of it worked it just kept going to the same screen and not starting up. Can anyone please help?! Is it completely cooked? What's causing this? I don't mind having to reset the whole hard drive if it comes down to that but will that fix anything? Please help....thanks!

I'll give my honest opinion, rather than a sales line.
1. MBPs with larger monitors are more highly correlated with logic/graphics board problems.
2. As the link suggests, no MBP can guarantee that you won't end up with a logic board problem down the road. However, 13" models have a good track record.
3. Any MBP user should be aware of the problems associated with heat. The temperature should be consitently lower than 145F, and never higher than around 170F at any time. Longterm gaming or using your MB on your lap are bad ideas.
Any MBP that's kept at 210F will end up with a logic board problem eventually. Solder connections loosen with higher temperatures, and the MB logic/graphics board is soldered in.
Updates are imminent for current MBPs - wait for those. http://buyersguide.macrumors.com

Macbook Pro 2012 Retina Won't Start, burnt power pins on power port, digital artist dead in the water

After a year of owning my macbook pro late 2012 retina model, it started having difficulty charging, it wouldn't charge even when green on the magsafe, and had difficulty turning orange, basically right after the 1 year warranty was over by one month, I went into the apple store and they told me that I simply needed to replace the power adapter and cord and it would be fine, but that it most likely was caused by me plugging it into a power strip, and that I had to plug it directly into the wall in its own power slot, which they never said that was what you were supposed to do when I purchased the laptop and could not find it anywhere in the literature. It was fine in the store for the apple worker, but after even just a few months I had to to constantly twist and unplug and replug the magsafe adapter from different angles just to get it to work, and it was like a living ****, as I am a digital artist and my wacom tablet will not work until my macbook pro is charging and the magsafe is orange, so everyday I would waste 30 minutes to an hour with the finicky magsafe, until recently my macbook pro will not turn on at all.
Since the problem arose after warranty I had to pay out of pocket for the replacement magesafe cord, which was a temporary solution, I pointed out that the magsafe power port on the laptop itself also had burn marks just like the magsafe cord that had a few pins pushed in and was slightly blackened but the attendant ignored that and said it was fine and just swapped out the cord. The "genius" attendant claimed if I just plugged in the macbook pro directly into the wall, everything would be fine and back to normal, and I did just that, I never plugged it into a power strip ever again, and still we arrive to my current predicament.
I believe I have to repair the actual power port the magsafe plugs into on the laptop, and get a new magsafe cord all over again, but it will be much more expensive than simply swapping out a cord this time, and I don't think the reason this happened to begin with has been truly identified, and I'm worried I have to make this repair every year, and I can't afford this kind of planned obsolescence, and I thought I was getting the best laptop in the world, and it was, everything was perfect not one single problem, except for this power issue, which now won't even allow me to use the computer at all and is now a giant paper weight, and leaves a dirty taste in my mouth when it comes to apple products.
I live in San Francisco in a house that was built around 1910 and don't know much about what or when renovations were made for power, but I have a feeling some kind of incorrect voltage is happening, and I was never instructed on this, and every other macbook is fine, my roommates have earlier models like the 2007 and 2009 MacBooks and have no problem like mine.
Please help me

I don't understand why and how the red light in the audio jack is still on while the computer is totally off, not connected to any power source and the battery seems to be empty... how is taht possible?
Because the battery is not empty, something is messed up, likley the SMC.
All I can advise is doing a SMC Reset, which resets the power firmware in case it got messed up and hopefully that will charge the battery up like normal.
If you can't do it or it doesn't work tommorow after charging up (turned off) overnight then just take it to Apple.

Macbook pro fell and won't start up

Last night my macbook pro fell from the table, it didn't look damaged on the outside, put it to sleep and went to sleep myself. This morning i opened it up and the rainbow wheel ket spinning whatever I did. Restarted it and same thing. I tried all the possible options suggested, different keyboard combinations at start up. Verified the disk using the original cd but by hard disk won't mount, i see the hard disk icon on the top left pane but if i click on it, i read not mounted on the bottom part of the panel. Tried disk utility starting the mac on retrieve mode and says "disk can't be repaired". Now if i shut down the mac and start it up again the apple logo appears and the gear keep spinning but nothing happens. Any idea what might have happened? It was working fine before yestarday. Lion os installed.
I also would like to backup the data on time machine but can't since the mac won't start up. Any suggestion?
Thanx

Take it to your local Genius Bar. They will be able to diagnose it there, and offer a solution.

MacBook Pro 10,2 won't start after online restore

I bought this MacBook to repair as it was sold with a 'stiff trackpad', i.e it wouldn't depress when it was clicked. The tap to click function still worked so it was still a perfectly usable laptop. Anyhow, the good news is that I fixed the trackpad issue, so it clicked fine! However, the bad news is that it only booted when connected to the mains, and was very laggy to use; animations etc were slow. So i tried an internet restore, which seemed to complete, and it now doesn't boot at all.
I got up to step 23 on this guide before putting thing back together- after that, the above issues arose, so I'm sure it could be a stupid error of mine:
https://www.ifixit.com/Guide/MacBook+Pro+13-Inch+Retina+Display+Late+2012+Trackp ad+Replacement/15484
Any help would be much appreciated.
Thanks!

The Internet Recovery you needed to do is this:
Install Mavericks, Lion/Mountain Lion Using Internet Recovery
Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard drive.
Boot to the Internet Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND-OPTION- R keys until a globe appears on the screen. Wait patiently - 15-20 minutes - until the Recovery main menu appears.
Partition and Format the hard drive:
Select Disk Utility from the main menu and click on the Continue button.
After DU loads select your newly installed hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Click on the Partition tab in the DU main window.
Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the process has completed. Quit DU and return to the main menu.
Reinstall Lion/Mountain Lion. Mavericks: Select Reinstall Lion/Mountain Lion, Mavericks and click on the Install button. Be sure to select the correct drive to use if you have more than one.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.
This should restore the version of OS X originally pre-installed on the computer.

MacBook Pro (Late 2008) won't start up

Since December 2012, my MacBook Pro (late 2008) refuses start up. After trying many, many things (from online forums - nothing worked), the solution I found by hit and miss is to heat up the back of the laptop in front of my fireplace (or with a hair dryer), to remove the battery, to wait a few seconds and then to put it back in; after doing this, it turns on without a fuss and remains in perfect running condition until I turn it off again. I now leave it on 24/7 when at home, and I don't dare taking it away with me again... Seems to me a contact got loose and the heat expands it just enough to make it work again. Manufacturing problem?
Has anybody else got the same or a similar problem? I hope to fix this without going to an Apple store if possible, as it's not under warranty any more...
By the way, I have since replaced the battery and the hard disk, but that particular problem remains; I'm running OS X 10.8.2.

It coule be one of two things:
1) Your hard drive has become corrupted, and you'll have to reinstall the OS and cut your losses.
2) Your logic board is fried. I seriously hope that this isn't the problem, but if it is, then it's time for a new mac.
My macbook pro was stuck on a bootup loop, and I finally had to reinstall the OS. This fixed my problem. On the other hand, I had this same problem on my iMac, and an OS reinstall didn't do anything.
Before making any judgements, take it to the genius bar and get some expert advice.

MacBook Pro is slow, won't start up

2.4 GHz Intel Core 2 Duo
10.9 Mavericks
I bought this computer on eBay. It ran fine the first couple of weeks, then I started having problems: really slow starting up (or won't start up, gets hung up on Apple screen, but WILL start up when I hold the shift button down), MS Office 11 package won't start up, every command is sllllllooooowwwwww.
Safari takes a full 60 seconds to boot, web pages take forever to load, all apps are slow to boot, commands are slow.
Help?

If you don't already have a current backup, back up all data before doing anything else. This procedure is a diagnostictest. It changes nothing, for better or worse, and therefore will not, in itself, solve your problem. The backup is necessary in case your startup drive is failing.
Third-party system modifications are a common cause of usability problems. By a “system modification,” I mean software that affects the operation of other software — potentially for the worse. The procedure will help identify which such modifications you've installed, as well as some other aspects of the configuration that may be related to the problem.
Don’t be alarmed by the seeming complexity of these instructions — they’re easy to carry out. Here's a brief summary: In each of two steps, you copy a line of text from this web page into a window in another application. You wait about a minute. Then you paste some other text, which will have been copied automatically, back into a reply on this page. The sequence is copy; paste; paste again. That's all there is to it. Details follow.
While investigating the problem, you may have started the computer in "safe" mode. If possible, these steps should be taken while booted in “normal” mode, not in safe mode. If you’re now running in safe mode, reboot as usual before continuing. If you can only boot in safe mode, you can still use this procedure, but not all of it will work. Be sure to mention that in your reply, if you haven't already done so.
Below are instructions to enter UNIX shell commands. The commands are safe and do nothing but produce human-readable output, but they must be entered exactly as given in order to work. If you question the safety of the procedure suggested here — which you should — search this site for other discussions in which it’s been followed without any report of ill effects. I am not asking you to trust me. If you can't satisfy yourself that these instructions are safe, don't follow them.
The commands will line-wrap or scroll in your browser, but each one is really just a single long line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, and you can then copy it.
Note: If you have more than one user account, Step 2 must be taken as an administrator. Ordinarily that would be the user created automatically when you booted the system for the first time. Step 1 should be taken as the user who has the problem, if different. Most personal Macs have only one user, and in that case this paragraph doesn’t apply.
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.
When you launch Terminal, a text window will open with a line already in it, ending either in a dollar sign (“$”) or a percent sign (“%”). If you get the percent sign, enter “sh” and press return. You should then get a new line ending in a dollar sign.
Step 1
Triple-click anywhere in the line of text below on this page to select it:
PB=/usr/libexec/PlistBuddy; PR () { [[ "$o" ]] && printf '\n%s:\n\n%s\n\n' "$1" "$o"; }; PF () { o=$($PB -c Print "$2" | awk -F'= ' \/$3'/{print $2}'); PR "$1"; }; { o=$(( $(vm_stat | awk '/Pageo/{sub("\\.",""); print $2}')/256 )); [[ $o -gt 1024 ]] && printf "\nPageouts: %s MiB\n\n" $o; o=$(kextstat -kl | grep -v com\\.apple | cut -c53- | cut -d\< -f1); PR "Loaded extrinsic kernel extensions"; o=$(launchctl list | sed 1d | awk '!/0x|com\.apple|org\.(x|openbsd)|\.[0-9]+$/{print $3}'); PR "Loaded extrinsic user agents"; o=$(launchctl getenv DYLD_INSERT_LIBRARIES); PR "Inserted libraries"; o=$(crontab -l); PR "User cron tasks"; o=$(cat /e*/lau*); PR "Global launchd configuration"; o=$(cat ~/.lau*); PR "Per-user launchd configuration"; PF "Global login items" /L*/P*/loginw* Path; PF "Per-user login items" L*/P*/*loginit* Name; PF "Safari extensions" L*/Saf*/*/E*.plist Bundle | sed 's/\..*$//;s/-[1-9]$//'; o=$(find ~ $TMPDIR.. $ -flags +sappnd,schg,uappnd,uchg -o ! -user $UID -o ! -perm -600 $ | wc -l); [[ $o -eq 0 ]] || printf "\nRestricted user files: %s\n\n" $o; cd; o=$(find -L /S*/L*/E* {,/}L*/{A*d,Compon,Ex,In,Keyb,Mail/Bu,P*P,Qu,Scripti,Servi,Spo}* -type d -name Contents -prune | while read d; do ID=$($PB -c 'Print :CFBundleIdentifier' "$d/Info.plist"); ID=${ID:-No bundle ID}; egrep -qv "^com\.apple\.[^x]|Accusys|ArcMSR|ATTO|HDPro|HighPoint|driver\.stex|hp-fax|JMicron|microsoft\.MDI|print|SoftRAID" <<< $ID && printf '%s\n\t(%s)\n' "${d%/Contents}" "$ID"; done); PR "Extrinsic loadable bundles"; o=$(find /u*/{,*/}lib -type f -exec sh -c 'file -b "$1" | grep -qw shared && ! codesign -v "$1"' {} {} \; -print); PR "Unsigned shared libraries"; for d in {,/}L*/{La,Priv,Sta}* L*/Fonts; do o=$(ls -A "$d"); PR "$d"; done; } 2> /dev/null | pbcopy; echo $'\nStep 1 done'
Copy the selected text to the Clipboard by pressing the key combination command-C. Then click anywhere in the Terminal window and paste (command-V). I've tested these instructions only with the Safari web browser. If you use another browser, you may have to press the return key after pasting.
The command may take up to a few minutes to run, depending on how many files you have and the speed of the computer. Wait for the line "Step 1 done" to appear below what you entered. The output of the command will be automatically copied to the Clipboard. If the command produced no output, the Clipboard will be empty. Paste into a reply to this message. No typing is involved in this step.
Step 2
Remember that you must be logged in as an administrator for this step. Do as in Step 1 with this line:
PR () { [[ "$o" ]] && printf '\n%s:\n\n%s\n\n' "$1" "$o"; }; { o=$(sudo launchctl list | sed 1d | awk '!/0x|com\.(apple|openssh|vix\.cron)|org\.(amav|apac|calendarse|cups|dove|isc|ntp|post[fg]|x)/{print $3}'); PR "Loaded extrinsic daemons"; o=$(sudo defaults read com.apple.loginwindow LoginHook); PR "Login hook"; o=$(sudo crontab -l); PR "Root cron tasks"; o=$(syslog -k Sender kernel -k Message CReq 'error|GPU |hfs: Ru|I/O e|find tok|n Cause: -|NVDA\(|pagin|timed? ?o' | tail -n25 | awk '/:/{$4=""; print}'); PR "Log check"; } 2> /dev/null | pbcopy; echo $'\nStep 2 done'
This time you'll be prompted for your login password, which you do have to type. Nothing will be displayed when you type it. Type it carefully and then press return. You may get a one-time warning to be careful. Heed that warning, but don't post it. If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator.
You can then quit Terminal.
To prevent confusion, I'll repeat: When you type your password in the Terminal window, you won't see what you're typing.
Note: If you don’t have a login password, set one before taking Step 2. If that’s not possible, skip the step.
Important: If any personal information, such as your name or email address, appears in the output of these commands, anonymize it before posting. Usually that won't be necessary.
Remember, Steps 1 and 2 are all copy-and-paste — type only your password. Also remember to post the output.

Macbook Pro A1226 screen won't turn on

I have a MacBook Pro A1226. The computer has been working fine, however tonight when I turned it on it made the chime booted up, and I could hear my applications running (Skype and Trillian were both making sounds), Caps Lock light goes on and off, keyboard lit up, however the screen seems to be completely dead. No backlight, and no activity. I hooked in an external monitor, and this made no difference.
Any ideas?

Well, went to the local apple store...the outcome wasn't good. The 'genious' had a 6 hour wait...I couldn't stand around there that long waiting to just talk to someone for a few mins, so that was a no go. The sales person looked at it and said that given the age, they don't carry parts for it anymore anyway I'm not sure if this is a complete lie or not since there wouldn't have been any point for them trying to talk to a 'genious' if that wasn't the case.
Took it to another store and they were basically saying the same thing that a new logic board would cost $1200...more than what a new one is worth.
I see numerous 'repaired' boards on ebay...does anyone have any expereince with these...how long can I expect it to work for etc. I'd like to get another year or two out of this machine if I can.
I'm hesitant on buying a new Mac at this point. They are literally 3 times the price of a comparibly powered PC (with the same parts in it) and the new ones are far too thin for my liking and no dvd drive (which I do use)....if this one has issues, I'd imagine a new one is going to have simular issues down the road...they're just too damned thin for it to have any reasonable level of cooling in it.
I guess I'm out of luck.
Anyone know what the computer would be worth for parts...

TS1411 Dropped MacBook Pro now it won't start

My daughter dropped my MacBook Pro yesterday.
Now when I turn it on I only get a gray screen.

MacBook Pros don't run 10.3. If you have rental/homeowner insurance, or insurance through the credit card that purchased it, you may want to find out what affect making a claim would do to your insurance before submitting a claim given what has happened. Sometimes you can restore without too much cost, but all depends on the status of any backup you have, and how hard it fell. But know your options before you pursue further.

MacBook Pro (Early 2008) won't start

Hello,
I have an early 2008 model MacBook Pro running Snow Leopard and Windows XP through Boot Camp. From searching, I can see that people have had issues booting but their computers had at least turned on - mine doesn't even get that far.
I went to use the computer yesterday and was unable to turn it on. I looked up the Apple support website on another computer and tried the two fixes there (I believe it is called resetting the PRAM and SRAM?) but still no luck.
The battery light indicates that the battery is fully charged and there is no indication on the computer that it is turned on, no light on the opening clip button thing and no light on the Apple symbol.
I am thinking this could be the Logicboard issue but I have never had a problem with video before.
Any help/advice?

Simular issue here.
Last night, I closed the lid, putting the machine to sleep, as always.
This morning, I opened the lid again, it started with a Black Srceen, so I though "Let's turn the backlight up" No function there "Reset display?" I closed and re-opened lid, nothing "Restart!" pushed power-button, followed by enter, still nothing, so I held down the power-button to completely kill the machine, then to boot it up. I pushed the power-button again... It started up the fan and disc-drive for 1.5 seconds, then shuts down again.
I've tried it all, reset SMC, PRAM, checked power-cord, check the battery, boot without battery, re-insert ram, but nothing!
It seems the power-supply goes on, asks the logic-board for activity, get's no answer, and commits suicied again.
I'm out of Apple-care, I live in Denmark, so no genius bar for me.
Thanks in advance!

Mac Pro - Grey Screen; won't start

I am having problems with my Mac Pro. Had to replace the graphics card last week as both cinema displays packed up (coloured lines all over both monitors) and the computer has been fine for the past day or so.
During some work tonight, the computer froze and completely stopped working - had to power down by holding down the power button. On restarting, the apple logo comes up but after a few seconds this disappears and, at the point where I expect the desktop to load, nothing happens. I have left the compute for 10/15 minutes to see if it starts but absolutely nothing happens.
Again, I am forced to power down by holding down the power button and the machine will not start at alll now.
Have reset PRAM but this has made no difference.
Grateful for all help and suggestions.

Mac OS X: Gray screen appears during startup

MacBook Pro crashed and won't start up!!! HELP!

I had a couple programs running (nothing out of the ordinary) and I opened Photobooth and then the screen turned black, but the little green light on the top of the laptop indicating that the camera is on was lit. I pushed a few buttons but the screen remained black so I figured I had a small crash (my very first one too).
I held the power button until the laptop shut off and I tried starting it back up, however the screen stays black and nothing seems to get it to work! I know the power is on since a light turns on when the laptop is on. Its the little light on the button you push to open your closed laptop (sorry I don't know what it's called).
I tried shutting the laptop on and off, removing the battery, letting it sit for 10 minutes... NOTHING'S WORKING.
Is my laptop dead??? Help!

I am guessing that you connected to your iMac while in target mode. If you could not pull the data off that way, and you can't repair the drive, it seems as if you have limited options.
You could run the hardware check on your system disk. If the HD is fried, you can send it to a recovery service ($$$$) if the data are valuable and not backed up. Otherwise, I would bring it to Apple (assuming that you are within warrantee/applecare) and have them replace it.
Good luck!

Macbook Pro's screen flickering pink lines?

My mid-2009 Macbook Pro's screen has recently started flickering pink lines in fields that are otherwise normally white (browser windows, text fields, etc). It happened spontaenously one day last week. The machine was never dropped or anything. At first, I thought smc reset and pram reset fixed it, but the problem has returned.
One small quirk: pressing down on the machine roughly in between where the two fans are temporarily fixes the issue, until I release it. Seating it on top of an object that applies pressure there also allows the screen to function normally.

Take it to an Apple store genius bar and have the techs test it...could be something as simple as a loose connector, or something more serious like a problem with the graphics module or the logic board.
