After software update my macbook pro has no video

After doing a regular software update on my MacBook Pro (2006/7 model) the display no longer works. I've been running Lion since it came out with no problems (until last night). I hear the chime and the power light is on. I've tried the different boot options and still no display. Booting off a snow leopard disc appears to be running okay (disc spins periodically) but still no video. I've also reset the PRAM/NVRAM. The battery seems fine.
Any help would be greatly appreciated!

If your computer is stuck restarting, hold the Power button to turn off your MacBook Pro and turn it on again. As the installation finished previously, nothing will get damaged

ITunes won't open after downloading software update. Macbook Pro OSX10.6.8 Simple solution?

iTunes won't open after downloading software update. Macbook Pro OSX10.6.8 Simple solution? And by the way, this is apparently a common problem and Apple has completely failed to warn in advance or offer a quick straightforward solution - used to be a good company, but it's becoming just another crappy screw-the-consumer corporation.

It would help to know versions here. I'm guessing your update put an older version of something into a place where a newer version of something iTunes put in there existed. Updating an earlier OSX version to 10.6.8 is still only updating to system software that was issued several years ago. If you are running some slightly newer version of iTunes issued subsequent to 10.6.8 and you just updated to 10.6.8 you may have put in an older version of something iTunes uses. Anyway, I'm guessing here until we know exactly what you did.

Hello,
after a sofware update, my macbook pro was supposed to restart,
since then the start up process begins & after few seconds, the mac goes back to off without starting, what's wrong ?
thanks for any support,
Amine

Let me add a little bit of details,
after the software update, I was asked to restart my laptop,
while doing it, I got a message error :"some files couldn't be updated".
Since then, everytime I start my macbook pro, I have the grey apple & screen, with a kind of updating bar (grey as well) at the bottom,
when the bar reaches approximately 30 to 40%, it disappears & the laptop swiths off.
Ihave tried to start on a safe mode, it doesn't work either,

Performance reduced under Bootcamp after EFI update on Macbook Pro Retina

after i upgraded EFI on my retina macbook pro the proformence reduced to unusable. under heavy load under bootcamp windows7. the cpu clock drops and as well as cpu clock. this is the screen shot of gpu clock monitoring from windows u can see the gpu clock is running at 270Mhz at most of the time and trying to be back to 725Mhz(yea, not 900Mhz!) when im running a graphic benchmark at same time cpu will run about 1.1Ghz as well. i noticed that it will run 10-20sec normally then CPU and GPU clock will start dropping. It's almost like speedstep is programmed backwards. My CPU is constantly running at 3.1-3.2GHz, and then as soon as a game loads, it drops to 1.2GHz. I've lost track of how many times I reset the SMC reseting SMC PRAM, reinstalling windows using Bootcamp or even erease the entire drive and start over from network recovery MacOS did not solve this problem. so all the recent games like COD MW3, Starcraft II, BF3,or D3 will only run about about 10 fps as i was playing them with no ploblem before the EFI update.
this is killing me! please help.
im in NY, in this season i dont think is the overheating problem. when i check the temperature, it stays about 80C (fans will run about 4k rpm). but some time heavy loaded Mac OS cpu is about 90 degree but only with 3k rpm fan kicked in.
i did search online, seems that some other people have the same problem with rMBP or MBA 2012.
anyone knows if i take my macbook pro to the store, will those people work at genuines bar help me with this "windows" problem?
thanks!

Hey Shadowyani, please take a time and fill a bug report at http://developer.apple.com/bugreporter/ . The machine is useless for me as it is now because I develop and use very GPU/CPU demanding scientific applications, after the update my realtime applications are completely useless as they drop from something like 25fps to 9 fps even on Mac OS X (no SMC reset fixed the issue). In bootcamp the situation is worse, my software runs at 4 fps and gaming turns to be impossible to play as well.
Please let Apple know about the problem, fill a bug report, even if SMC reset once in a while fixed the issue for you (this is not a common behaviour and must be fixed). We paid the price for cutting edge technology.
Apple shall not do a downgrade of the system after few weeks, remember that most of reviews and benchmarks were done BEFORE the EFI Update, so people are being fooled by Apple in this sense.

Gray Screen after Yosemite update on MacBook Pro

I have a Macbook Pro from the fall of 2011 and receny updated from Mavericks to Yosemite. The installation seemed to go okay, took like eight hours, but started at first. Then once I opened an application it shut down and tried to restart. It went to a gray screen and then to a gray screen with a restricted symbol, or whatever you want to call it, as pictured below.
Before the update, the computer would shut down for no reason and restart with the message, "Restarted due to problem", or something like that. I had repaired and cleaned the disk using Onyx, and it seemed to have stopped the problem, but the way it shut down this time seemes just like that. Now I cannot get it past this screen... Please help, guys :/

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.

Performance reduced after EFI update on Macbook Pro Retina

after i upgraded EFI on my retina macbook pro the proformence reduced to unusable. under heavy load( under mac os or windows7) the cpu clock drops and as well as cpu clock. this is the screen shot of gpu clock monitoring from windows u can see the gpu clock is running at 270Mhz at most of the time and trying to be back to 725Mhz(yea, not 900Mhz!) when im running a graphic benchmark. cpu will run about 1.1Ghz as well.
samething will happen when im playing D3 on Mac OS.
Reseting SMC and PRAM did not help! reinstalling windows7 via bootcamp did not help either.
i there any one here having the sam trouble?

Here is a conclusion of this bug from Hong Kong:
I have had this issue with my rMBP bought in early launch period, i believe it is the first batch.
Then, i bought another one with customization, which is believed is FRESH and a newer batch. NO SUCH ISSUE!
I have compared this 2 machine with different batchs and here is the result:
Cooler about 5-10 degree
No throttling under load, both CPU & GPU
use less power of CPU Package and CPU IA Cores according to AID64
lower voltages of CPU Core
3dmark 06 constant at around 15000
3dmark 11 around 2500
3dmark vantage around 10800
with driver 306.97
Are we just help Apple to improve their product at our cost?

Slow startup after Mavericks update in MacBook Pro (MD102HN/A)

After the Mavericks update, my MacBook seems to lag at startup, starts really slowly. Especially when the lock screen is about to appear and the Apple logo kind of slides upwards. Does anyone else face the same problem or is it just me? The slide always lags!

Remove all items in System Preferences > Users & Groups > Login Items
Same for /Library/StartupItems
Then restart your Mac to test.
And check to make sure there's enough free disk space.
Click your Apple menu icon top left in your screen. From the drop down menu click About This Mac > More Info > Storage
Make sure there's at least 15% free disk space. Less can slow your Mac down.
If nothing above helped, the startup disk may need repairing ...
Launch Disk Utility located in HD > Applications > Utillities
Select the startup disk on the left then select the First Aid tab.
Click: Verify Disk (not Verify Disk Permissions)
If DU reports errors, restart your Mac while holding down the Command + R keys. From there you should be able to access the built in utilities in OS X Recovery to repair the startup disk.
Make sure to back up all important data first before using OS X Recovery.

Updating my MacBook pro has messed up my keyboard

i updated MacBook pro tto Yosemite last night and this morning when I tried to search something in Google it just wouldn't type what I wanted. it now types z & x at random and various other keys don't respond as they should. Anybody know how to fix this?

Reset NVRAM/PRAM
Try it a couple of times.

After an update my MacBook Pro didn't start, All it does is beep!

Download the latest update on my MacBook Pro 13 "and restarted when the screen did not lit and began to beep, and it beeb like 9 times...what can I do to make it start! I'm desperated, I need to work!

The RAM isn't an issue - did you JUST install 10.8.3 BEFORE this happened? Nonetheless, you SHOULD be able to boot into your Recovery partition (unless it's completely hosed). Try booting into Internet Recovery - holding down the Command, option and R keys whilst booting. It will take a while for the screen to come up - you'll see a globe onscreen while you're booting from Apple servers - and use Disk Utility from there to verify and if needed repair your disk and then reinstall a fresh copy of Mountain Lion. DO NOT erase your disk.
Call back...

Getting this error when trying to run latest software update on MacBook Pro

Everytime I try to run the update, it starts to download and then I get this error:
The operation couldn’t be completed. (NSURLErrorDomain error -1102.)(102)
I'm not too sure what it means, or how to fix it. If someone could help me out, that would be great!
Thanks!

You might try this:
Repair the Hard Drive and Permissions - Lion/Mountain Lion
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
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 then click on the Repair Permissions button. When the process is completed, then quit DU and return to the main menu. Select Restart from the Apple menu.
Then download and install: OS X Mountain Lion Update v10.8.5 (Combo).

Can't reopen iPhoto after installing update on MacBook Pro.

I installed an update for iPhoto yesterday and now find I cannot reopen it. When trying to install, it gets to 50% of step 2 and then quits. Is there any way I can save my photographs, which aren't backed up anywhere other than iPhoto?

The iPhoto application and iPhoto Library are separate items.
All your photos are inside the iPhoto Library package, and that is what you should backup asap!
Your iPhoto Library is by default in your Pictures folder and called iPhoto Library.photolibrary.
Drag this package to an external drive to make a backup copy.
Do you have any Fire wall enabled or Anti Virus software running? If yes, turn it off, while you are running the installer.
If that does not help, boot into SafeMode, while installing, see: Mac OS X: What is Safe Boot, Safe Mode?
Or, if this still does not help, sign into a different administrator account and run the installer from there. You are not by any chance running out of disk space?
See How to Access Files in iPhoto
to get access to your photos without iPhoto.
