Do a backup. Boot the Recovery Partition (command - R on a restart) and run Disk Utility. In the first Aid tab, select the top level hard drive and see if GUID is shown (see below). Run Disk Utility Verify/Repair and Repair Permissions until you get no errors. Then re-install the OS.

I lost everything on my iPod and iTunes (the app) is telling me I have to buy my music and videos all over again. How can I reinstall them without buying them again??

As long as you have the files stored on itunes from your computer or backed up, you should be to connect your ipod to computer and sync your music back onto your ipod.

Repairing the permissions of a home folder in Lion is a complicated procedure. I don’t know of a simpler one that always works.
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 page that opens.
Drag or copy — do not type — the following line into the Terminal window, then press return:
chmod -R -N ~
The command will take a noticeable amount of time to run. When a new line ending in a dollar sign ($) appears below what you entered, it’s done. You may see a few error messages about an “invalid argument” while the command is running. You can ignore those. If you get an error message with the words “Permission denied,” enter this:
sudo !!
You'll be prompted for your login password, which won't be displayed when you type it. You may get a one-time warning not to screw up.
Next, boot from your recovery partition by holding down the key combination command-R at startup. Release the keys when you see a gray screen with a spinning dial.
When the recovery desktop appears, select Utilities ▹ Terminal from the menu bar.
In the Terminal window, enter “resetpassword” (without the quotes) and press return. A Reset Password window opens. You’re not going to reset the password.
Select your boot volume if not already selected.
Select your username from the menu labeled Select the user account if not already selected.
Under Reset Home Directory Permissions and ACLs, click the Reset button.
Select  ▹ Restart from the menu bar.

Erased mac book pro (2009), how can i reinstall osx? it won't recognize any old system disc

erased mac book pro (2009), how can i reinstall osx? it won't recognize old system discs

Did you try:
Install or Reinstall Mavericks or Mountain Lion from Scratch
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.
OS X Mavericks- Erase and reinstall OS X
OS X Mountain Lion- Erase and reinstall OS X
OS X Lion- Erase and reinstall Mac OS X
Note: You will need an active Internet connection. I suggest using Ethernet if possible
            because it is three times faster than wireless.
If you don't have the original discs that came with the computer, then you can install the retail version of Snow Leopard:
You can purchase Snow Leopard through the Apple Store: Mac OS X 10.6 Snow Leopard - Apple Store (U.S.). The price is $19.99 plus tax. You will be sent physical media by mail after placing your order.
After you install Snow Leopard you will have to download and install the Mac OS X 10.6.8 Update Combo v1.1 to update Snow Leopard to 10.6.8 and give you access to the App Store. Access to the App Store enables you to download Mavericks if your computer meets the requirements.
     Snow Leopard General Requirements
       1. Mac computer with an Intel processor
       2. 1GB of memory
       3. 5GB of available disk space
       4. DVD drive for installation
       5. Some features require a compatible Internet service provider;
           fees may apply.
       6. Some features require Apple’s iCloud services; fees and
           terms apply.

You are allowed to have two machines with activated installations, so if you only had one installation, you still have the option to install on a second without doing anything further than that. If you originally downloaded the purchase thru Adobe then you might find a download link available in your Adobe account online. You can also download thru the following page if you can find your version:
Download and Installation Help -
https://helpx.adobe.com/download-install.html
You can have the first installation deactivated to free up the activation and have it available for another machine again as well. YOu need to contact Adobe Support thru chat for that. For the link below click the Still Need Help? option in the blue area at the bottom and choose the chat option...

Help, my computers are all stolen (4). How can I reinstall my CS5?

Help, my computers are all stolen (4). How can I reinstall my CS5?

With all of your computers stolen you cannot reinstall anything.
What specifically is your problem? Do you own the discs or do you need to download? Do you need to get your serial number for CS5? Do you need to have someone deactivate your software for the stolen machines?

Grey Screen, won't boot from usb. Only have a PC to create a boot USB. How can I reinstall OSX with a .dmg file?

I recently recieved a macbook that I was told was broken. She didn't know what was wrong with it, but she told me I could keep it if I wanted to get it working again. Its http://support.apple.com/kb/sp579 this model. I got the laptop to power on, but the apple logo and the spinning wheel under it kept spinning forever. So with me and my "Amazing" knowledge of Macs, I thought it would be best to reformat the drive on my PC via sata cable to FAT32 (which I was told is a format that mac devices can read/write on) and install OSX from usb. So I have a .dmg file and used TransMac to format the usb and make the usb drive bootable with the .dmg.
I formatted the drive to FAT32 and plugged it into my macbook and I get a folder and a question mark blinking on the screen. After looking at some forums online, I found that the error occurs when you don't have the correct filesystem to boot or something along those lines. So I try rebooting the computer while holding C, to boot from an external device (such as USB). Nothing. Again the folder and question mark blink on the screen. I look at some other boot option keys and try all of them. Shift for recovery mode, D for apple hardware test, Control, option, P, and R for resetting NVRAM and PRAM. Everything! The only things that differ slightly are when I press Option for startup manager, N for NetBoot and Option+N for internet default boot image. When I press N and Option+N, I get a blinking globe for about 5-10 seconds and then the folder and ? blink again. When I hold Option for the startup manager, I get a white screen and my curser, which I can move around the screen, but there is nothing to click on, its just white.
Currently I have a USB flash drive plugged into the macbook with a .dmg OSX installer on it via TransMac and for some reason, my macbook doesn't want to try to load it. Either I have the wrong file format for the installer, or my macbook is having problems. I read that the hard drive may be the problem, except I can use it on my PC so I know that it works fine.
If anyone has any information about how to fix this, or any ideas. Please let me know! I would very much like to get this macbook going again.

The correct format for Mac OS X is not FAT-32.
As the computer shipped with an install-restore disc DVD set that could be used to start the computer as an emergency disc and use the Utilities on the Installer, without running the Installer itself, to format, attempt repair, and perform a few different system installs or reinstalls, this is where the correct format would come from.
Was there documentation to confirm the build year and model information, such as to refer you to the product page link you posted above?
If accurate, that MacBook shipped with this custom grey
install-restore DVD version of Snow Leopard:
Original OS
Mac OS X 10.6.1 (10A2047)
Maximum OS
Latest release of OS X
AirDrop
Supported
Hardware Test
AHT 3A181
And to be able to restore the basic OS X to that level, official replacement discs for that computer should be ordered from AppleCare; to facilitiate obtaining correct ones, you should find the product serial number. There likely would be a fee involved. The replacement disc set may have a different number than the one in the information box above, but would match the hardware series by Apple standards. And a replacement disc may not have the original extra applications that shipped with the computer when new. Those original discs are part of the retail computer, an essential part number, like the power adapter, and should be included with the computer even after an OS X upgrade, since they allow basic access without using the internet.
The remainder of the Snow Leopard 10.6(.8) would be a download Software Update Combo v 10.6.8, either direct from Apple servers or through the computer's running Software Update. Once the computer is up to date in Snow Leopard, 10.6.8, then one could visit the Mac App Store, App Store, and iTunes Store; from the Mac App Store, and you could check/get the latest upgrade to Mac OS X, 10.9.2. An Apple ID is required to access.
The computer may not support Mavericks 10.9.2, or may be able to, but could use an upgrade of RAM capacity.
If your model and build year series info is correct:
Maximum Memory
8.0 GB (Actual) 4.0 GB (Apple)
Memory Slots
2 - 204-pin PC3-8500 (1066MHz) DDR3 SO-DIMM
For more information see the database download http://mactracker.ca
and also compare specs with macbook models at everymac.com.
The newer OS X systems that can use a Recovery HD partition on the hard disk drive, can start from there to repair their hard disk drive, and reformat the section where the Mac OS X runs, and reinstall that. Since there is no likelihood of that still being on the drive once it was FAT-32 reformatted, it will not be present to assist in attempts to reformat the drive; if the computer had been upgraded past Snow Leopard 10.6, to a later system that would have used the recovery partition, or the later internet recovery system. That goes to Apple Servers to use OS X Utilities and reinstall the system, helpful for computers without optical drives or system media. Your MacBook with 10.6.8 installed, then had to access the Mac App Store, to get 10.7.5, 10.8.5, or 10.9.x
Identify your Mac lookup by model number or serial number:
https://www.powerbookmedic.com/identify-mac-serial.php
Anyway, the hardware in the computer may need some inspection, troubleshooting, and maybe repair; but the original DVD install-restore disc has an Apple Hardware Test on it, for that series build model macbook. That could help in troubleshooting some aspects of the computer. Could be the hard disk drive failed; or if someone tried to upgrade the RAM, the system may not have worked correctly. Hard to say how it was messed up, at this stage. There are several possible causes.
Hopefully you can get the correct disc set from AppleCare.
You can call Support number, or use Contact Support page.
Good luck & happy computing!

I just upgraded my iPhone4 iOs and lost ALL Phone Contacts! How can I get them back?

HELP! I've been using my iPhone consistently for ALL phone numbers, since I have serious memory problems due to fibromyalgia. I upgraded my phone last night finally, having moved my photos out of it I had the space to download and install the upgrade.
I got a nasty shock this morning when I tried to make a routine call and found ALL of my phone contacts missing. They don't seem to be either in the cloud or in the phone. What happened? It said it was storing them in the cloud but they're all gone! How can I get them back?
IF this normally happens, why should I ever upgrade? Seriously! I didn't think to copy all of it out manually before upgrading, I'd upgraded once before without any problems. Addresses and other details gone too. I've got four numbers in "Favorites" but no context for them beyond location by state. I don't even know who they are - can't recognize just the numbers.

Thanks, but I checked iCloud and it has none of them.
If it backed up to my laptop, that died and I just got the new computer. The one that's crashed won't even boot, so there's no way to even tell if it was syncing the contacts along with all the phone photos. Literally happened at the same time - it was because I had the new computer that I was finally able to pull the photos off the phone and make room for the upgrade. It had refused to upgrade for lack of space for some time.
I had thought it was set to sync to iCloud but it vanished from BOTH my phone and the cloud. That's why I'm so angry about it.

I just opened Foxfire and it automatically imported bookmarks from safari, but not all of them. How can I get the rest of them ?

I still have Safari on the computer with all my bookmarks. Not all of them came over to Firefox. How can I get them over. Also I had some in the toolbar that displayed over the window. Does this browser have that feature?

Export the bookmarks in Safari to an HTML file and import that file in Firefox.

TS2755 Now that my husband has an iPhone5 as well, he receives all the messages sent to me, and my replies to them. How can I keep my messages private?

Now that my husband has an iPhone5, he receives all the messages sent to me, and I receive his. Do I have a setting wrong? How can we keep our messages private?

Go into the settings app.
Settings > Messages > Send and Receive from
Set each phone to send and receive only from the specific phone number assigned to the phone and the specifics one number of each user.
If you each are using the same App,e ID I suggest one of you getting a different ID to keep all your stuff separate. I also recommend that each of you have different email addresses.

I only wanted to restore my settings but i ended up restoring everything (i.e. all data got deleted), how can i get my pictures and books back?

How can i return my phone back to what it was 10 minutes ago and no i haven't backed up my phone since last year so i do a restore from what i have in my computer, this will only return my phone back to what it was a year ago. please help.

If you haven't backed the device up in a year, and you did not copy the pictures and other data off before restoring it, then your stuff is gone.
It is important that you back up your data, just like with your computer, regular backups are vital for recovering data when things happen.

My HDD, recovery disk and OSX all of them deleted, how can i reinstall OSX?
