Macbook pro (lion) will not reboot after updating itunes

downloaded itunes update and computer will not reboot. I get grey screen with apple and swirling icon. Have tried turning on and off, and putting into safe mode but nothing has worked. HELP

Actually my MacBook pro is 2011 model! I managed to install Lion on an external disc and start my MacBook from it. Although the internal disc is seen I cannot retrieve my data. Anyone knows how I do that please?

As I mentioned above, I am not very tech savvy so I have no idea why a wireless protocol would be showing up there, I'm just listing everything I see in hopes that someone might know something I can try. This is why I am asking for help here - I'm not sure what has happened that has made me unable to connect, especially since it seemingly occured while nobody was using the computer.
I guess I should clarify that I'm not a total hillbilly- normally my firewall is set to 'on', but I set it to 'off' to try and troubleshoot the issues here as I was told that sometimes it can interfere with the computer's ability to connect to the internet. If this is not the case and firewall does not affect anything, I will turn it back on while I try to fix this.
I have tried the method you mentioned above a few times - I actually contacted my ISP earlier this week and they recommended resetting the router like that. They didn't mention any known network issues.

Permissions will not repair after update itunes 11.1

Permissions will not repair in Mountain Lion 10.8.5 after updating Itunes to version 11.1

These days it's quite normal to get a long list of 'errors' on doing a permissions repair because Disk Utility has not been upgraded to allow for some changes made to the system.
As long as at the bottom of the list it says 'Permissions repair complete' you can safely ignore them all.

Mid 2010 Macbook Pro battery will not charge after plugging in firewire cable shut down computer

I have a mid 2010 15" Macbook pro with Lion installed.
I was running off battery, and I went to plug in a firewire cable, not plugged into anything, and when I inserted it, the computer shut off.
The computer would not turn on again without being plugged into the AC adaptor. The magsafe charger shows green, but the computer says not charging. The battery is showing 57%, but the indicator lights will only light up when AC charger is connected..
I have let it sit off, and plugged in for a couple hours, and nothing chages, and let it sit overnight not plugged in, but nothing.
I have read other forums about the same issue,, it seems like its a common issue, and some have said what it could be, but no one said what it IS.
I have tried resetting the SMC and PRAM, but to no avail.
When i plug in the AC adaptor, the computer immediately turns on (which I find kond of funny), and I am able to turn it off normally, and it will stay off, and I can also turn it on if the charger has been connected from pervious.

My imac will not restart after updating itunes. What do I do?

I have just updates iTunes to use my new iPod nano. The computer attempted to restart and I have been left with the grey apple start up screen. Is there anything that I can do to resolve this?

See if you can get back in with a Safe Boot. Shutdown (hold power button in until it does, if necessary), hold down Shift at the startup chime and give it much longer to boot. Might try repairing Permissions while in Safe Boot, from Disk Utility. Also Verify Disk. No need, as Safe Boot should do this.
After doing that, and if it will then boot normally, get the iTunes update from Apple Downloads and reapply it.
If it was the 11.01, get it here.

Itunes will not open after update, itunes will not open after update

i have just updated itunes following trying to link my apple tv to itunes on my computer. i was advised an update was required first, agreed, and have not been able to open itunes since.

Well then I would attempt a complete uninstall and reinstall of an earlier version of iTunes-
should be able to find one somewhere. Also review your automatic system restore settings
for future problems. I have used system restore multiple times for issues like this.
It really is a quick fix.
Do you have an Apple Store somewhere near where you live? You could make an appointment to
talk to a tech there. I think that's free.

Make certain that your MBP is connected to an AC source and is charging or charged.
Then try a SMC and PRAM resets:

I have a MacBook Pro that will not boot up. The apple symbol is there and the spinning wheel keeps spinning. Any idea how I can fix this?

Reinstall OS X.
Reinstalling Lion/Mountain Lion Without Erasing the Drive
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 the Hard Drive and Permissions: Upon startup select Disk Utility from the main menu. Repair the Hard Drive and Permissions as follows.
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 click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu.
Reinstall Lion/Mountain Lion: Select Reinstall Lion/Mountain Lion and click on the Continue button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.
OR
Reinstall Snow Leopard 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 Combo Updater for the version you prefer from support.apple.com/downloads/.

HT1338 how do I boot a MacBook pro that will not shut down

HOw can I reboot shut don MacBook pro that will not shutdown, please help.....?......

Hi, I'm having similar problem. I just got a Lacie ext drive to back up my photos and vids and now my laptop wont shut down or go to sleep properly. May or may not be related to Lacie. Could just be a coincidence.
I first noticed problem when I closed it to go to sleep and the apple logo kept flashing on and off.
When I opened the laptop the screen was flashing white then black, then white then black. Had to force shut
it down (opt, cmnd,power), had to hold it down a very long time before it responded. However, that didn't keep it shut down. It just started back up again. But at least it wasn't flashing.
Then when i tried to shut it down normally it would shut down, go black for a moment and then the Apple song would play and it would start back up again. It also won't stay asleep. It sleeps for two seconds when put into sleep mode then snaps awake.
strange problem... Very annoying. Next option is to unplug and let battery run out.

My macbook pro battery will not hold charge

My macbook pro battery will not charge. The laptop will only turn on after it has been plugged in to charge, and when unplugged it automatically dies. When plugged in the battery indicator is green and the top right corner of the screen says "Not charging". I left town for a week with the laptop off and I came back in town and it won't charge. What can I do to fix this?

If you are under warranty call Apple and get a case number.

I HATE my new MACBOOK PRO, it will not let me open any PDF files and I downloaded the ADOBE READER three freaking times and it keeps saying that all the files are corrupt. I would rather have my 2008 Dell at this point. what is wrong with this thing

I HATE my new MACBOOK PRO, it will not let me open any PDF files and I downloaded the ADOBE READER three freaking times and it keeps saying that all the files are corrupt or damaged. I would rather have my 2008 Dell at this point. what is wrong with this thing

Perhaps the PDF files are corrupted.
Hit the command key and spacebar, a blue Spotlight in the upper right hand corner appears, now type Preview and press return on the Preview program.
Now you can try opening the PDF's from the file menu and see what's going on.
If they are corrupted, perhaps they are trojans from your Windows PC or gotten from a bad location online.
Download the free ClamXav and run a scan on the possibly infected folder.
