My computer went black yesterday, and when I restarted it, Firefox had been uninstalled! What happened?

I was working on my computer yesterday, and it suddenly went black. I checked the connections to make sure that it hadn't just run out of power d/t battery running out, but the electric connections were fine. I restarted it, and Firefox had been uninstalled within the couple of minutes that it took to re-start it. Gone! I've tried to reinstall it, but got a message asking if I really wanted to do that, as it could be bad for my computer to go ahead. Also, I just tried to add the troubleshooting info, and it looks like all of my documents are wiped, too. Help!

This morning my computer did some updates and when it was done I had no mail icon anymore

This morning my MacBook Pro did some updates and after it restarted I had no mail icon anymore and have no idea how to get it back to read my email. Can anyone help me with this?

To reinstall a Mac OS X application (Address Book, iCal, iChat, iTunes, Mail, or Safari):
Insert the Mac OS X installation disc into your computer’s optical drive (or an optical drive connected to your computer), double-click the Optional Installs folder, and then double-click the Optional Installs package (looks like an open box).
NOTE:If your computer came with other Mac OS X install media, reinstall Mac OS X to reinstall Mac OS X applications. For more information about Mac OS X install media, see:Mac OS X install media
Follow the onscreen instructions. Select the disk where you want to install the application and click Continue.
Click the disclosure triangle next to Applications, select the checkbox for the application you want to install, click Continue, and then click Install.
After you reinstall a Mac OS X application, open Software Update (choose Apple menu > Software Update) to update the application.

Battery could be at EOL. Try getting it replaced.

I have it set on manually manage music and videos. So there is no automatic syncing going on or anything like that. Yes iTunes was open and when i plugged in my phone i could see all the music and everything on my phone, everything was working like it was supposed to, I didn't have a problem until I unplugged the phone.

If your phone is not covered by the warranty anymore, Apple will replace it for a new device, same model and size, if you are willing to pay the service fee.
If you decide to get a 3rd party company to do the repair, Apple will not service your phone anymore after that.
Out-of-warranty repair service
If your repair isn’t covered by Apple’s One Year Limited Warranty, AppleCare+, or AppleCare Protection Plan, your iPhone might be eligible for out-of-warranty service. For example, liquid damage isn’t covered by warranty but might be eligible for out-of-warranty service. Some damage isn’t eligible at all, for example if your device has been broken into multiple pieces. See Apple’s Repair Terms and Conditions for complete details.

Try Reset iPad
Hold down the Sleep/Wake button and the Home button at the same time for at least ten seconds, until the Apple logo appears

I am running out of hard drive space so I clear 32GB of space at midnight, went to bed. When I wokle up I had no space left even though I had not used the computer, the system.lg is FULL of stuff and I have no HD space anymore? What's eating it up?

WORD TO THE WISE
the OmniDiskSweeper was a very helpful download, because it laid out the HD and all the files on it in a "largest to smallest" fashion. When I did this I found that I had an inordinate amount of memory being taken up in my Mail Data folder, this did not make much sense so when I dug deeper I found that a 59MB scanned file that I had emailed 3 weeks ago had not been delivered, so the computer was retrying every minute and saving the history of what it was doing, so it was saving the 59MB file as well as the log about the 59MB file and hence for the last 3 weeks it's been chewing away at HD space recording the activity of the undeliverable file.
I deleted the Data record folders and removed the yahoo account from My Mail and reinstalled it with proper IMAP information and the HD is secure and holding at 331GB of free space. Like it ought to be.
I love the fact that if something very strange is happpening on your MAC there is a REASON....find it and fix it, and move on. In the PC world you would reboot 20 times, call some guy in India who will ony try to sell you a new subscription or warranty for $99 and never solve anything.
I am at rest once more, thanks for the tip

To "update software" and when I restarted my computer I got the message unable to complete. Now when I restart my computer it is shows the apple and a continuously turning time gear.

I responded to install new software message and was asked to restart--I did that--went to lunch and when I returned my screen showed the message that said, "unable to complete update for unknown reason" or something to that regard-and asked me to restart. I tried to restart and now see the apple but the time scroll is in an unending loop and my computer will not boot.-I recently installed snow leopard in order to be able to sync my mobile me accounts--since then my computer runs hot. Not sure if that has anything to do with current issue.

You will need to reinstall Snow Leopard:
Reinstall OS X 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 appropriate Combo Updater to return to the Snow Leopard version you prefer from support.apple.com/downloads/.

Please tell us what kind of computer you have, what operating system and what version of iTunes. Not just "the latest version of iTunes", the exact version number.

My computer was dropped yesterday and it will not turn on past this gray screen that tells me to reboot it but everytime I reboot it, it just goes back to that same screen and tells me to do it again. Anyone know how to fix this?

When you jar or drop a hard drive when it's operating the heads strike the platters and ruin sectors and the data on them.
Your getting the spinning wheel because the OS has been damaged and/or quite possibly the drive.
You'll first have to determine if it's a hardware issue
Do #3 Hardware Test and #5 Disk Utlity Repair Disk/Permissions here (check the SMART status)
Step by Step to fix your Mac
If the drive is fine and you don't have a recent copy of your data off the machine then also do this
Create a data recovery/undelete external boot drive
Then proceed with fixing the damaged software, likley by #8 your problem will be fixed.

Apple TV worked until today. Message says unsupported signal check your output device. I have checked hdmi cable with another device and it's fine. Put on a different tv and same message. Went out yesterday and bought a new Apple TV and same problem.

Which TV do you have.
You may wish to try the following:
Press and hold the menu and the up button simultaneously on the remote for six seconds, the Apple TV should then begin to cycle through the various resolutions available to it at 20 second intervals.. If you see a picture appear up on your screen, use the remote to scroll down to the OK option and select it.

I have an iPhone and when I got it, I had a Toshiba laptop. Now I have a MacBook Pro, but when I try to wi-fi sync my iphone and new computer, it doesn't work because on my iphone it is still trying to sync with my old computer. How I can fix this?

Move the content from the old computer to the new computer.
Sync the iPhone via cable to the new computer and enable Wi-Fi syncing.
It should now be possible to sync via Wi-Fi to the new computer.

Hi Vickey, S,
Sorry for the delay in response. Is it happening with all the files?
Also, please write the steps you are taking to type in the document.
You might try uninstalling and re installing the Reader in case it is happening with all the files.
URL to install the Adobe Reader is Adobe - Adobe Reader download - All versions
Thanks,

If you have exceeded your allowance of 5 machines then Apple will not allow you to authorise additional Computers. If you still have access to your old toshiba fire it up de-authorise it and then try again with the new computer.
While this won't help if you are having password problems, I did want to point out that you do not need to access old machines to de-authorize them. Once you are signed in at the iTunes store, access "my account" by clicking on your username in the top navigation bar. Then "manage devices". You can remove any old machines that way.

My computer crashed and I have to buy a new one. What happens to my Contacts, Photos, etc when i use the new computer? I do not have an iTunes backup.

Do you have the iCloud set up? If you don't you need to buy a third party software that will do it for you when you plug your phone into the new computer. You can google: iPad/iPhone/iPod to Computer Transfer. You have to pay for the software but it's really a life saver and you get free updates for life. It'll save you a lot of pain and suffering in the future. I've used it many times.
