When we update our computer, do we have to backup everything?

If we software update on our mac, do we have to backup everything?
Does the update thing erase everything on our computer?

I backup every two weeks using Time Machine.  I don't normally backup before every software upate, but then again, I do curse at myself when somethings do go wrong.
Software update do not erase everything on the computer.

    We were able to update iPhones but get an error message when trying update our iPad. Ay suggestions?

    What iOS are you currently running?
    If you have an iPad 1, the max iOS is 5.1.1. For newer iPads, the current iOS is 6.1. The Settings>General>Software Update only appears if you have iOS 5.0 or higher currently installed.

    If you are currently running an iOS lower than 5.0, connect the iPad to the computer, open iTunes. Then select the iPad under the Devices heading on the left, click on the Summary tab and then click on Check for Update.
    Tip - If connected to your computer, you may need to disable your firewall and anitvirus software temporarily.  Then download and install the iOS update. Be sure and backup your iPad before the iOS update. After you update an iPad (except iPad 1) to iOS 6.x, the next update can be installed via wifi (i.e., not connected to your computer).

  • When we got our computer it all ready had 2 user names on it Administrator and Teacher and we dont know the passwords for them.

    When we got our computer it all ready had 2 user names on it Administrator and Teacher and we dont know the passwords for them.

    Assuming you have been able to set yourself up as an Administrator so far, you can just go into Applications>System Preferences>Users & Groups and delete the other three accounts by highlighting them one at a time in the left hand column and clicking the "Minus" symbol at the bottom of the column.
    If you have NOT been able to set yourself up as an Administrator also so far, then the following article should help:

    I don't know about the systems, but is your phone on wireless and your other device on wireless?  Then I think they would mutually update.
    Howerver the previous response from ckuan sounds much more informed so I would check that out.

  • When i update my computer does everthing get erased ?, when i update my computer does everthing get erased ?

    when i update my computer does everthing get erased ?, when i update my computer does everthing get erased ?

    No, content remains unless you specify something like an erase and install.  It is always a good idea to make a backup before updating just to have more protection.

    Hi Imminnie,
    Thanks for using Apple Support Communities.  If iTunes doesn't recognize your iPod touch, this article may help:

    If issues persist, a thorough removal and reinstall of iTunes would be the next thing to try:

    When i updated my computer, my safari on applications wont open and says "safari quit unexpectedly" and wont open but when i open it on the application key on the mac, safari will open. how do i get safari back on my dock where it will open. when i click reopen it wont. but i know safari works because thats what im using right now. it just wont open when i click the one i had loaded on my dock and in applications. please help!
    Stephanie

    Drag the Safari icon straight up and off the Dock so it goes, "poof" ...
    Now click and hold the Safari app in the Applications folder and drag that to the Dock.
    See if you can open a webpage in Safari.

  • When I update to ios5 will I have acess to Siri?

    When I updated to ios5 do I have access to Siri?

    Siri is only a feature of the iPhone 4S. There is no information out there to suggest the iPhone 4 will get it later. Just going by history, most of the time Apple will just forget about the previous products and just look to the next device. Siri is only still a Beta at the moment anyway so they still need to perfect it before it is added to any other devices.

  • If I were to update to Maverick, would I have to reinstall everything I had on my mac before the update or will it remain installed??

    If I were to update to Maverick, would I have to reinstall everything?

    No.
    Nothing is removed and older versions of Apple software are updated.

  • Getting weird error message when booting up our computer

    when booting up our iMac, we get a gray screen with an error message in 4 languages saying: "you need to restart your computer"
    upon restarting, we keep getting the same message.
    at the same time we noticed that the screen was very fuzzy... I re-starting holding commandoption+pr to re-set the pram. that worked to get the screen clear, but i still ended up on the same message.
    after a few re-starts, the screen went back to the fuzzy view.
    I have also already checked the led lights on the back to assure that the power supply was working appropriately, and i got all 3 lights ON and solid. the 4th light (overheating) was not coming on...
    any ideas or recommendations??
    Tks

    What you are seeing is called a 'Kernal Panic'.

    Try this:
    Repairing permissions is an important part of regular maintenance, and should always be carried out both before and after any software installation or update.
    Go to Disk Utility (this is in your Utilities Folder in your Application folder) and click on the icon of your hard disk (not the one with all the numbers).
    In First Aid, click on Repair Permissions.
    This only takes a minute or two.

    If you were having any serious problems with your Mac you might as well complete the exercise by repairing your hard disk as well. You cannot do this from the same start-up disk. Reboot from your install disk (holding down the C key). Once it opens, select your language, and then go to Disk Utility from the Utilities menu. Select your hard disk as before and click Repair.
    Once that is complete reboot again from your usual start-up disk.

  • Flash quits working when I restart my computer and I have to uninstall and reinstall every time

    HELP! I've been working on this for 11 hours non-stop!
    I have Windows 7 64bit. I'm using the newest Firefox browser. I install Flash and it seems to sort of work. It is in my Control Panel Uninstall programs with the Flash icon.
    When I restart my computer and go to the Adobe site it shows that Flash isn't working. It's still in the Control Panel Uninstall programs BUT it has no icon. So I have to uninstall it and reinstall it to use it.
    When I go to any Zynga.com games and right click on the game window the Flash window opens but when I click on Settings it freezes and I have too right click and left click a lot for it to go away. So I can't allow the site to use 100% of Flash to run on the site. Once in a while if I wait a few minutes Settings will open and I set it to 100% but when I go back and look at it later it says I am using 0%.
    I have Norton 360 and have turned it off and uninstalled and reinstalled repeatedly only to have the same problem occur.
    Before I installed Windows 7 and had Vista Ultimate it worked better but still not as good as it should have.
    Also in my Firefox plugins Shockwave is there but no Flash plugin is ever there with Flash installed or uninstalled. Should Flash be there and where did Shockwave come from? Firefox?
    Do I need Shockwave for Zynga or Facebook games? Or at all for that matter. I'll install it for no good reason as long as it doesn't screw something up.
    After 11 hours of this Adobe HELL I am burnt! So ANY help is greatly appreciated!
    Thanks to anyone who can help me. THANK YOU!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
