  • If I reinstall OSX will I lose my apps?

    I want to reinstall OSX - Finished a year at uni and have a load of stuff I don't need. Just want to wipe and reinstall so it's fresh again. Problem is I have a couple of apps I downloaded from app store (cheap ones like angry birds), but couple of more expensive ones like Call Of Duty. Will I lose all these? Is there anyway of backing them up to re-install?
    Thanks, Christian.

    First, unless you have a good reason - and just having "a load of stuff" is not a good reason - a clean reinstall of the OS is extreme on a Mac.  It should only be necessary for very severe problems.
    Second, if you wipe the hard drive, then everything not backed up will be lost, of course.  However, note that you can re-download apps purchased through the Mac App Store, so they won't be truly gone.
    As for backups, see my Mac Backup Guide.

  • If I reinstall OSX will I lose data?

    My 4.5 year old iMac has got some sort of glitch.  When I turn it on it does not progress any further than a blue screen.  Sometimes some error messages appear to say that something or other had quit unexpectedly.  The error messages had three options ignore, report and relaunch but I was unable to select any of them.
    I took it it the Genius Bar and the bloke there was able to start it when he plugged something into it and said that the data was still there.  He did some diagnostics and the hardware was all ok.
    He seemed to think that there was a problem with the operating system and that if I had access to another Mac I might be able to treat it as some sort of external drive and retrieve the data from there, and then re-install the operating system I might be able to sort it out even if that meant wiping everything off and starting again.  Unfortunately my allotted time ran out. 
    I am now the owner of a MacBook Pro, I have plugged them together and I can see the other computer but Finder only says 'connection failed'.
    Back to my original question if I use my original Install Discs to re-install OSX, will this mean that I will lose everything?
    Cheers,
    Cameron

    1. Doing that requires using a FireWire connection and starting up the iMac with the T key held down. Ethernet and wireless connections require a bootable OS.
    2. No. Back up the data anyway; see #1.

  • TS1702 I am having problems with an app that won't open.  If I uninstall it then reinstall it will I lose all of the data that I have stored there?

    I tried to update ipages app and this failed.  I now cannot open the app.  I am still unable to update it.  If I uninstall and reinstall it will I lose the data stored on it

    Try downloading any small-sized free app and then try Pages again.

    Your library should be fine, but you ought to backup routinely anyway.

    No. Reinstalling the application does not affect your files.

    No, your library will remain - but you should be keeping and maintaining a backup of your downloads/library.

    You should have your data backed up off the computer regardless because even though a OS X upgrade doesn't affect users files, something could go wrong and the only way to fix it would be to erase everything and reinstall from scratch.
    And like Neil said, removing OS X itself involves erasing the entire drive or partition and that of course removes programs and files in the process as OS X manages everything.
    If your having a problem, there is the #8 Reinstall Just OS X, and this doesn't really erase it, but overwrites the present copy with older one from the 10.6 disk, then you use Software Update under the Apple menu to get back to 10.6.8.
    But you should grab a copy of your files off the machine first if possible, because you might be having drive issues.

  • I'm getting a message that itunes must be reinstalled.  Will I lose all my saved songs and playlists

    I believe there was a recent update to itunes.  I tried to install it, but the process could not be completed.
    Now I am getting a message that itunes must be reinstalled.  If I reinstall it, will I lose my 1400+ songs on my computer, and playlists too? 
    How will my iphone5 be impacted?
    Thank you.

    I have installed iTunes fresh a lot of times, the library is still there
    I sugest backups in case the library goes south

  • If I reinstall Windows, will I lose my iCloud photos?

    If I reinstall Windows, will I lose my iCloud photos? If so is there a way of backing up the images and putting them back into iCloud?

    Use Windows Backup to safeguard the files, then use it to restore them.

  • HT4718 If I reinstall OSX, will it erase my files?

    If I reinstall OSX, will it erase my files?

    It's difficult because the OS X volume can't be shown so you can't access to the files inside, so you will probably have to use an application like DiskWarrior or a data recovery company in order to recover the files. Note that you should make backups of your data to prevent this situation, so you have a copy of your files and nothing would have happened with your data.
    Apart from that, you can find hard drives at OWC > http://eshop.macsales.com/shop/hard-drives/2.5-Notebook/ HGST drives have a good reputation and work correctly

  • If i uninstall and reinstall skype will i lose voi...

    Hi,
    If i uninstall and reinstall skype will i lose voicemail messages?
    Thanks
    Ben

    Hi, Benluke! 
    Most uninstallation procedures tend to avoid deleting UGCs (User Generated Content.) That's not to say that I can guarantee they'll stick either. 
    Have you listened to any of these voicemail messages yet? 
    If so, it has been transferred to the PC you listened to it on and is located at:
    C:\Users\username\AppData\Roaming\Skype\SkypeUsername\voicemail
    No other computer with Skype installed will be able to retrieve it. 
    If not, it is still on Skype's servers and will remain there for no longer than 60 days from the time and date it has been sent to you. 
    That being said about Voicemail, you may notice that these are saved in .DAT files. I really don't want to leave you in the dust, but, so far, every resource I've exhausted has literally left me in the dust. You won't be able to play these files outside of Skype and I can't guarantee you that these files will be read by Skype the same way after an uninstall, reinstall and replacement of these files. 
    You can use some third-party tools to record your voicemails, such as call recorders developed for Skype. Perhaps you can back the voicemails up with one. I do apologise that I can't give you the most direct solution. 
    Should you choose to uninstall Skype, please keep me posted and let me know how the voicemail messages turn out (and what solution you chose to take.) You'll greatly help those who have wondered about this, present and past! As always, don't hesitate to ask if you've got more questions!

  • HT1296 was using my daughters itunes account and now have my own. If I "erase and sync" will I lose my data from my purchased games? I have transferred apps and backed up to my computer.

    was using my daughters itunes account and now have my own. If I "erase and sync" will I lose my data from my purchased games? I have transferred apps and backed up to my computer.

    One computer iTunes can support multiple Apple IDs.  One iPod can also support multiple IDs.  Don't do an "erase and sync."  Simply add your Apple ID to the computer's iTunes and to the iPod.  The only nuisance is app updating, especially if you do the updates from the computer, rather than from the iPod.

  • HT1212 If I never synced to itunes and I restore the device. Will I lose unstored data? How can I check to see the last time my phone was backed up if I forgot the passcode to my phone?

    If I never synced to itunes and I restore the device. Will I lose unstored data? How can I check to see the last time my phone was backed up if I forgot the passcode to my phone?

    If you can't remember your passcode, you'll need to restore your phone.  If you never synched to iTunes, all data on your phone will be erased.  No way around this.
