I was installing a new update on my MacBook Pro. With only 20% left it said "an unknown error had occured, please restart your computer." Now that I've restarted - I can't log in!
Ok, my MacBook haven't had any issues earlier, until today. At first Safari was acting kind of weird in that sense that a lot of letters were missing when you went on certain webpages, so I thought of updating since an alert-window popped up and notified that new updates were ready to be installed. So I opened up App Store through my Applications-folder and selected update.
First it asked if I wanted to connect my Mac to a powersource but since I had charged the battery to 79% I didn't think it was necessary. So I continued, computer restarted and began installing the updates.
Everything went fine until it was approximately three minutes left. An error message popped up and said something like "An unknown error has occured. Please restart your computer and try again". I pressed OK, rebooted my computer and when it asked for my password I typed it in. After I pressed OK, the computer indicated it was the wrong password. I tried multiple times and sometimes with different passwords... so now I can't simply log in! What's the problem?
TL;DR - Updated mac, failed after five minutes and now I can't log back in since "I have the wrong password"

I was trying to run ITunes 10.7 update on my Mac Pro with Retina dispaly but "An error has occurred" and I was not able to proceed with the update. The message says "The operation was cancelled. (3072)." I have no other messages. Any ideas why I cannot install this update
Scott's solution fixed the problem. It would have been helpful if the update message in the App Store had reported that. I had first tried B Noir's solution -- and received a helpful warning message that a guest user was still logged in to iTunes. I switched over, logged the guest user out, switched back and the update within the App store worked perfectly.
It seems to me that Apple should invest a little time and effort in making their error/warning messages easier to decipher. I have to come to the forum every time something happens. Why not simply have a dialogue window that opens up to explain the most likely issues? -
I was in the middle of installing the new update using the wifi at a local restaurant when I lost the wifi signal and my iPhone shut down, and now I can't get into the phone. I only get the iTunes logo with the cable pic. What are my options now?
Your only option is to connect your iPhone to your computer via USB (as the diagram indicates) and restore using iTunes.

I installed the new update and it is frozen with a picture of the charger head, and an arrow pointing to a iTunes icon. How do I get my phone to work properly?

After installing a software update on my Macbook Pro, it would not reboot passed the gray screen and then would shut down.
Take each of these steps that you haven't already tried. Stop when the problem is resolved.
Step 1
The first step in dealing with a boot failure is to secure your 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 your last backup, you can skip this step.
There are several ways to back up a Mac that is unable to boot. You need an external hard drive to hold the backup data.
a. Boot into 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.”
b. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, boot 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.
c. 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
Press and hold the power button until the power shuts off. Disconnect all wired peripherals except those needed to boot, and remove all aftermarket expansion cards. Use a different keyboard and/or mouse, if those devices are wired. If you can boot 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.
If you've booted from an external storage device, make sure that your internal boot volume is selected in the Startup Disk pane of System Preferences.
Step 3
Boot in safe mode. Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Post for further instructions.
Safe mode is much slower to boot 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 your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
When you boot 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, your boot volume is damaged and the drive is probably malfunctioning. In that case, go to step 5.
If you can boot and log in now, empty the Trash, and then open the Finder Info window on your boot 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 reboot as usual (i.e., not in safe mode.)
If the boot process hangs again, the problem is likely caused by a third-party system modification that you installed. Post for further instructions.
Step 4
Sometimes a boot failure can be resolved by resetting the NVRAM.
Step 5
Launch Disk Utility in Recovery mode (see Step 1.) Select your 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 reboot as usual.
Step 6
Reinstall the OS. If your Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
Step 7
Repeat step 6, but this time erase the boot volume in Disk Utility before installing. The system should automatically reboot into the Setup Assistant. Follow the prompts to transfer your data from a Time Machine or other backup.
Step 8
This step applies only to a Mac Pro tower, not to any other model. A dead logic-board battery can cause a gray screen at boot. Typically the boot failure will be preceded by loss of the startup disk and system clock settings. See the user manual for replacement instructions.
Step 9
If you get this far, you're probably dealing with a hardware fault. Make a "Genius" appointment at an Apple Store to have the machine tested. -

Can't install SMC Firmware Update for my MacBook Pro 15" early 2011
Can't install SMC Firmware Update for my MacBook Pro 15" early 2011
Check your Network control panel and turn off Auto-Proxy setting.
This is one of the top #4 "how can they do this' pet-peeve errors.
The other is the often slow 8 hrs to download 600MB even on 10Mb+ cable.
Another, 'the drive cannot be partitioned because there isn't enough contiguous unfragemented free space; some files are locked and cannot be moved."
If auto proxy isn't it, router/modem and DNS settings. -
I have a macbook pro with only 128gb of hard drive. I have lightroom installed and all my photos on an external hard drive. Can I store my lightroom library on the external hard drive too?
Yes. Find the LR catalog file by looking in Edit/Catalog Settings/General. Close LR and navigate to that spot. The catalog file is the one that ends in .lrcat - move it to wherever you want. Next to the .lrcat file is a subfolder called Previews.lrdata. You can move that over as well, but if you don't LR will generate new previews. Double-click on the .lrcat file in its new home and LR will open with that catalog. Set Preferences to When Starting Up Use Most Recent Catalog.

I have a MacBook Pro Late 2011 and I'm wondering if I install Windows 7 Ultimate to this MacBook Pro with this Full Retail Version. And if so, which bit to use either 32-bit or 64-bit since I have both disks.
64 bit.
32 bit won't use all your computer's ram.
64 bit allows you to run 32 bit programs
Your computer is 64 bit
New programs use 64 bit.
There is no reason to use the 32 bit version of Windows. -
Hello. I have an iphone 3gs 8gb factory unlocked. Currently its running on ios 5.0.1 and I am trying to update it ios 5.1.1 but its not updating. The itunes downloads the ios 5.1.1and gives back unknown error(3194). Please help.
Unable to contact the iOS software update server gs.apple.com
Error 1004, 1013, 1638, 3194: These errors may be the result of the connection to gs.apple.com being redirected or blocked. Follow these steps to resolve these errors:
Install the latest version of iTunes.
Check security software. Ensure that communication to gs.apple.com is allowed. Follow this article for assistance with security software. iTunes for Windows: Troubleshooting security software issues.

Try to restore from another known-good computer and network.
If the errors persist on another computer, the device may need service. -
I WAS INSTALLING THE IOS6 UPDATE ON MY I PHONE 4S AND THE SCREN TURNED BLACK NOW WE CANNOT GET IT TO COME ON OR DO ANYTHING ANY IDEA WHAT I NEED TO DO
you may put your device in dfu mode then connect it to itune ,after that there may be a message come up and say you have to restore your device. Restore your device to 5.1.1 then when you finish update it from itune not from your device directly.

I received a 'pop up' asking if I wanted to update the software in my iPhone. As I always accept these messages to keep my phone up-to-date, I accepted.
A long (25minute) process started, but at the end of it, the process "crashed" saying an unknown error had been encountered!.NOTHING has changed with my computer of my iPhone, so I say this is an Apple problem. I cannot start or use my phone now - all that shows on the screen is the iTunes logo and a connectivity graphic - see attached photoHi Kalaivani Krish18,
If you are having issues with your iPhone attempting to update, you may want to try the troubleshooting steps in this article -
