I was stunned to discover that the Restore feature allowed others to get into my gmail account even after the computer had been shut down and restarted. How can this be prevented?

We have a PCin our shared vacation home running both Firefox and Explorer . When I tried to log into my gmail, Firefox took me automatically to one of my sister's accounts. In an effort to get to my own account, I shut down the computer. When I rebooted and restarted Firefox, it asked if I wanted to restore earlier session, and Lo & Behold I was back in my sister's email account. This is scandalous! How can it be prevented?

Hi,
You may have to disable (uncheck) '''Active Logins''' in '''Tools''' ('''Alt''' + '''T''') > '''Options''' > '''Privacy''' > '''Settings''', if it is enabled. Additionally you may also have to change to '''Use custom settings for history''' beside '''Firefox will''' and enable '''Clear history when Firefox closes''', if '''Settings''' is disabled or not visible.
Also, please note that it's always a safe practice to sign out of websites completely on shared PCs.

  • Use ipad2 to play video on Apple TV but cannot get the video to play on the iPad even though I change setting without shutting down and restarting the ipad.

    I have been using my ipad2 to show video on my flatscreen using the Apple TV.  Recently I find that once I use Apple TV I cannot switch back to the ipad for viewing even if I go back to the little rectangular screen and change the checkmark to ipad.  Once this happens all my videos will only play through apple tv.   If I shut down the ipad and restart it I come up in the ipad mode and can view it on the pad. 

    Welcome to the Apple Community.
    Not really sure on this one, but one thought I have is how full is your iPad. Have you connected your iPad to iTunes recently.

    Your only option is to connect your iPhone to your computer via USB (as the diagram indicates) and restore using iTunes.

    Unplug it and let unit go dead. Then hold your Home button down and plug the USB power cord back in. iTunes should see it and then restore.

  • With iOS 7 and certain apps I get a message that ask me to connect to iTunes to receive notifications. After clicking "OK" it comes back repeatedly and freezes the App: Friends, Dropbox, among others. The only way to escape is to shut down and restart.

    With iOS 7 and certain apps I get a message that ask me to connect to iTunes to receive notifications. After clicking "OK", it comes back repeatedly and freezes the App: Friends, Dropbox, among others. The only way to escape is to shut down and restart. I think this is a "bug" with older apps. How can I solve it in orther to use the apps? It doesn´t occur with my iPad, only with my iPhone 5.

    Thankyou for your kind answer: with Dropbox, it solved the problem; with Friends, still the same

    When I try to open iPhoto I get a window dialog that says...
    Your photo library is either in use by another application or has become unreadable
    Shut down and restart your computer, and then open iPhoto again. If the problem persists, try rebuilding your photo library. To do this, quit iPhoto, and then reopen it while keeping the Option and Command keys pressed. You can also try restoring your photo library from a backup.
    I have tried the reopen it while keeping the Option and Command keyes pressed.
    No change.
    I dee nothing but a blank page,
    Any help would be appreciated.
    Also hace back ups of all images on cd's. dvds and jump drives.
    Any advice is appreciated.

    Option 1
    Back Up and try rebuild the library: hold down the command and option (or alt) keys while launching iPhoto. Use the resulting dialogue to rebuild. Choose to Repair Database. If that doesn't help, then try again, this time using Rebuild Database.
    If that fails:
    Option 2
    Download iPhoto Library Manager and use its rebuild function. (In early versions of Library Manager it's the File -> Rebuild command. In later versions it's under the Library menu.)
    This will create an entirely new library. It will then copy (or try to) your photos and all the associated metadata and versions to this new Library, and arrange it as close as it can to what you had in the damaged Library. It does this based on information it finds in the iPhoto sharing mechanism - but that means that things not shared won't be there, so no slideshows, books or calendars, for instance - but it should get all your events, albums and keywords, faces and places back.
    Because this process creates an entirely new library and leaves your old one untouched, it is non-destructive, and if you're not happy with the results you can simply return to your old one.

  • My MacBookPro (mid 2012) will not complete the boot process. Yosemite's progress widget gets about 1/3 to 1/2 way across when the logo disappears and the screen goes all white for 10-15 secs or so, then the machine shuts down and restarts.

    My MacBookPro (mid 2012) will not complete the boot process. Yosemite's progress widget gets about 1/3 to 1/2 way across when the logo disappears and the screen goes all white for 10-15 secs, then the machine shuts down and restarts. This sequence will repeat seemingly forever unless I shut it down manually.
    I upgraded to Yosemite from Mountain Lion a couple months ago, skipping Maverick completely, and I've done any associated updates that Apple told me about. I don't recall which version of Yosemite I have, but I'm sure it is the "latest and greatest".
    I've tried re-starting in Safe Mode / Safe Boot and that does the same thing as described above except without the endless restarts. Instead of restarting at some point, SafeBoot proceeds to the white screen and then it hangs until I restart it manually. (I've waited as long os 20-30 minutes with no response).
    When I tried the option-command-p-r key combo I never get any chimes or other noises besides the original 1 time boot sound that you would expect to get when starting up a macbook pro.
    I was using the mac quite normally (meaning I was doing work I normally do on it and there was no indication of anything wrong) immediately prior to this happening.
    The machine is BootCamp(ed) with Windows 8.1 which I use from a VMWare virtual machine instead of natively so that I can have both OSes running at the same time. I also think this is unrelated to my problem. I have been using this setup for more than 2 years.
    My upgrade to Yosemite was uneventful and I thought it went well and was very smooth. I don't want to lead attention away from Yosemite, but at this point my problem does not seem related to the upgrade.
    Any help is appreciated.

    Install or Reinstall OS X 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.
    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.
    Erase the hard drive:
      1. Select Disk Utility from the main menu and click on the Continue button.
      2. After DU loads select your startup volume (usually Macintosh HD) from the
          left side list. Click on the Erase tab in the DU main window.
      3. Set the format type to Mac OS Extended (Journaled.) Optionally, click on
          the Security button and set the Zero Data option to one-pass. Click on
          the Erase button and wait until the process has completed.
      4. Quit DU and return to the main menu.
    Reinstall OS X: Select Reinstall OS X and click on the Install button.
    Note: You will need an active Internet connection. I suggest using Ethernet if possible
               because it is three times faster than wireless.

    Backup and restore your software via iTunes. If the problem continues, restore as a NEW device. If this solves it, that means there is some corruption in your backup file. If the problem is still there, you should take it to the Genius Bar at an Apple Store for evaluation.

  • I tried to reload my Ipod touch.  I accidently selected "start new ipod" icon on the Ipod and then "back up existing ipod" on Itunes.  Now the Ipod is unresponsive, constantly shutting down and restarting.  Even after multiple "forced" shut downs.  Help!

    After updating the os, I tried to shut down, clear and reload my Ipod touch.  Here's where I goofed:  at the prompt for starting the reload process, I selected "start as new Ipod" on the Ipod, but in Itunes, I selected " back up existing Ipod from computer" or something like that.  Now the ipod is constantly shutting down and restarting and no controls can be accessed.  All I can do is the "forced shut down" which I have done multiple times and let sit for a half hour off. 

    Disregard,  hooked up to itunes and clicked on summary, selected restore, all is well.

  • This just started happening.. I open Itunes and the little round rainbow loading indicator just goes on and doesnt stop.. My itunes wont function.. It gets stuck. Then i have to force quit.. I tried to shut down and restart. also reloaded the latest itune

    This just started happening.. I open Itunes and the little round rainbow loading indicator just goes on and doesnt stop.. My itunes wont function.. It gets stuck. Then i have to force quit.. I tried to shut down and restart. also reloaded the latest itune 11.1.3 and it still gets stuck.
    i use an external HD and thats fine.. all files are in there.  But I have no idea why my itunes app is getting stuck.
    Am I the only person this is happening to? What can I do to correct this problem?

  • When I try to use iMessage on my iPod touch 4 (ios6) the iPod shuts down and restarts

    Every time I try to open my iMessage my iPod shuts down. I have a 4th gen iPod with ios6. I will attempt to open the app and it will either shut down and restart as soon as the white screen comes up or I will see my previous messages and try to open a thread then it will restart. I have tried restarting the phone as well as turning iMessage on as off. Has anybody else had this problem? What can I do?

    Try:
    - Reset the iOS device. Nothing will be lost      
    Reset iOS device: Hold down the On/Off button and the Home button at the same time for at
    least ten seconds, until the Apple logo appears.
    -Note this will delete messages currently on the iPod:
    Go to settings>Messages>Send and Receive and sign out of Messages and sign back in.
    - Reset all settings                 
    Go to Settings > General > Reset and tap Reset All Settings.
    All your preferences and settings are reset. Information (such as contacts and calendars) and media (such as songs and videos) aren’t affected.
    - Restore from backup. See:                                               
    iOS: Back up and restore your iOS device with iCloud or iTunes
    - Restore to factory settings/new iOS device.                       
    If still problem, make an appointment at the Genius Bar of an Apple store since it appears you have a hardware problem.

    Reinstalling Lion Without the Installer
    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. Alterhatively, 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: Select Reinstall Lion and click on the Continue button.
    Note: You can also re-download the Lion installer by opening the App Store application. Hold down the OPTION key and click on the Purchases icon in the toolbar. You should now see an active Install button to the right of your Lion purchase entry. There are situations in which this will not work. For example, if you are already booted into the Lion you originally purchased with your Apple ID or if an instance of the Lion installer is located anywhere on your computer.
