Will my files and my contacts be deleted if i upgrade to mountain lion?

i am desperate to upgrade to mountain lion in a few days so just needed to be sure about that.

Two things about operating system installation.  The first thing is what is called a clean installation.  This happens a few different ways, first it could happen on a brand new hard drive that doesnt have an operation system, or it could happen if you wanted to erase your hard drive and start over (like if you were selling your computer).
An update installation of an operating system leaves all your applications, settings, files, etc in place.  This is provided nothing goes awry during the installation.  If something does go wrong, that is why we back up before attempting this.

    You'll have to purchase, install and update Snow Leopard from the Apple Store to get the App Store application.
    Mountain Lion is only sold via the App Store.

    Upgrading to Snow Leopard, Lion, or Mountain Lion
    You can upgrade to Mountain Lion from Lion or directly from Snow Leopard. Mountain Lion can be downloaded from the Mac App Store for $19.99. To access the App Store you must have Snow Leopard 10.6.6 or later installed.
    Upgrading to Snow Leopard
    You must 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 Mountain Lion 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 MobileMe service; fees and
               terms apply.
    Upgrading to Lion
    If your computer does not meet the requirements to install Mountain Lion, it may still meet the requirements to install Lion.
    You can purchase Lion by contacting Customer Service: Contacting Apple for support and service - this includes international calling numbers. The cost is $19.99 (as it was before) plus tax.  It's a download. You will get an email containing a redemption code that you then use at the Mac App Store to download Lion. Save a copy of that installer to your Downloads folder because the installer deletes itself at the end of the installation.
         Lion System Requirements
           1. Mac computer with an Intel Core 2 Duo, Core i3, Core i5, Core i7,
               or Xeon processor
           2. 2GB of memory
           3. OS X v10.6.6 or later (v10.6.8 recommended)
           4. 7GB of available space
           5. Some features require an Apple ID; terms apply.
    Upgrading to Mountain Lion
    To upgrade to Mountain Lion you must have Snow Leopard 10.6.8 or Lion installed. Purchase and download Mountain Lion from the App Store. Sign in using your Apple ID. Mountain Lion is $19.99 plus tax. The file is quite large, over 4 GBs, so allow some time to download. It would be preferable to use Ethernet because it is nearly four times faster than wireless.
         OS X Mountain Lion - System Requirements
           Macs that can be upgraded to OS X Mountain Lion
             1. iMac (Mid 2007 or newer)
             2. MacBook (Late 2008 Aluminum, or Early 2009 or newer)
             3. MacBook Pro (Mid/Late 2007 or newer)

  • Will Photoshop CS6 work with Snow Leopard or must I upgrade to Mountain Lion on the Mac Book Pro?

    I will be purchasing PhotoShop CS6 & installing on my Mac Book Pro. Adobe tells me that I should upgrade to Mountain Lion from Snow Leopard in order for it to work best. Any thoughts on this? Thank you, Paul

    You can use it on Snow Leopard without any problem. However, Apple updates graphic drivers and more things, so it could run better on Mountain Lion, but as I said, if you don't want to upgrade, keep on Snow Leopard because it will run properly.
    Probably, Adobe is referring to the fact that Photoshop could be working in 32-bit because the kernel on Snow Leopard starts into 32-bit by default, and Mountain Lion is a 64-bit operating system. In this case, you will see an improvement

  • Will i loose all my time capsule data if i upgrade to mountain lion from snow leopard

    i am thinking about upgrading from SL to Mountain Lion
    is there anything major i should be concerned with?
    will my time machine backups be availible?
    i mainly use Logic Pro

    Ok, then it looks like you need to start "from scratch:"  Power it off for a couple of minutes, then back on, and follow the manual.
    Be sure it powers-up and the yellow light comes on.
    If you don't have the manual that came with the TC, it should be one of these:
    Time Capsule 802.11n (1st Generation) - Setup Guide
    Time Capsule 802.11n (2nd Generation) - Setup Guide
    Time Capsule 802.11n (3rd Generation) - Setup Guide
    Time Capsule 802.11n (4th Generation) - Setup Guide
    I'm not an expert on that, plus it's late here, and I need to go to bed soon.  If you still have trouble with this, your best bet will be to start a new thread in the Time Capsule forum at: https://discussions.apple.com/community/wireless/time_capsule.  That's where the networking gurus hang out.

  • I upgraded to Mountain Lion and now I can't use any of my software!

    What a disaster and huge mistake.  Upgraded to Mountain Lion and now I can't run Autocad 2012 for Mac, any of my Adobe Creative suites software such as Photoshop, Illustrator.. and now I can't even do upgrades because Mountain Lion doesn't allow me to launch DMGs.  I've lost thousands of $'s in software, not to mention time, but most importantly now I can't even work!  I just tried to revert back to Snow Leopard by intalling it back in my hard drive and it won't let me.  I never used Time Machine.  Is there any way on earth I can revert back to my old operating software???  Please help.  And if you haven't upgraded yet and are thinking about it.  BEWARE - and don't do it.  I've been reading that Mountain Lion isn't working with Microsoft applications either.  Omy...I haven't even checked that. 
    and of course no one at Apple support can or will help me

    It's not my Microsoft that I use much or am worried about.  I can't run AutoCAD.  and I can't update AutoCAD either.  When I try to mount an update just to get it working, it says it can't run the DMG file.  Apparantly this new platform doesn't use Rosetta - which is needed to run any of these updates or downloads.  ***?  and then When I try to open CS4 appliations - Adobe Photoshop, Illustrator, or InDesign - I get the message "Licensing for this product has stopped working - Error 150:30 - ***? 
    So basically I can't use ANY of the programs I ran before.  And yes I have googled desperately all day.  Adobe has some suggestions - like deleting a Flex files - which I did...Defragmenting - which I did.  And most importantly provides am Adobe Licensing Repair tool to fix - which I can't open because Mountain Lion won't mount the DMG in order to run it!  It's a complete disaster and I don't have the money or time to purchase and or reinstall everything.  I am just screwed. 
    No you are not, calm down, cbs20 already gave you the answer on opening dmg files, updates are available for most of your programs and I assume you have licenses for the Adobe products. AutoCad you'll have to wait for.
    And please .... Start Backing Things Up, you could lose it all without one, work included.

  • Upgrading to mountain lion, deleting everything I have on Lion

    I have so much rubish on my mac at the moment, its going quite slowly and often crashes. I want to upgrade to mountain lion, with everything being deleted, and everything I have done/changed on lion to be undone (basically like new). How do i go about doing this?

    Obviously, make sure you first archive anything such as photos and documents that you do not wish to permanently erase.
    Boot OS X Recovery and choose Disk Utility from the OS X Utilities screen. Choose the volume containing Lion from the left column - usually it is named "Macintosh HD" - then click Erase. This will take only a moment.
    When it finishes, quit Disk Utility, and choose Reinstall Mac OS X from the Utilities screen. You will be asked for the Apple ID you used to purchase Lion, if it was not already installed on your Mac when you bought it. When it completes the Mac's Setup Assistant will appear in which you configure a new account. Don't be surprised when your personal information such as name, address, and phone numbers are automatically populated. These are gathered from Apple using your Apple ID, not from any information on your Mac.
    After you log in to your account for the first time, purchase Mountain Lion from the App Store and install it.
    That's it!

  • Should I delete iChat Icons folder after upgrading to Mountain Lion?

    I just upgraded from Snow Leopard to Mountain Lion. I see an IChat Icons folder alias in my Pictures folder.
    Is the original file folder that it references used for anything in Mountain Lion? For example, can Messages access it?
    Should I delete the alias and the original now that I have upgraded to Mountain Lion?
    thanks,
    Kevin

    Hi,
    I am booted into Yosemite and the version there called Messages 8 (It is also Messages 8 in Mavericks but they are significantly different)
    I see this and I think the labelling has changed
    This is the lower end of Defaults.
    At the top of the Apple User account selection. (see below)
    That is followed by the iChat Icons selection. That is the Flags, Flowers and Fruits, guitars, planets and masks plus the Pokemon like ones and the gems
    I have always found it defaults to the Recents "folder".
    I am struggling to remember how it was in Messages 7 in Mountain Lion.

  • I want to upgrade to Mountain Lion on my 2gb MacBook Air.  Will it operate ok?

    I have a MacBook Air purchased in May 2009 and have Lion on it.  It seems to have become a bit slow and clunky!  I now want to upgrade to Mountain Lion.  Will the 2GB memory cope with it or not.  Am I able to put additional memory on my Air?

    The MBA's RAM isn't upgradable and while the SSD can be upgraded with third party drives, it voids the warranty. Your computer should run Lion acceptably fast but Mt Lion is a bit of a stretch for a 2GB computer, even with an SSD. Plus, if your computer has something dragging it down with Lion, it isn't likely to get any better with the upgrade to Mt Lion.
    If you want to start tracking down the cause of your slowdown start looking at your hard drive free space (you should have 10-15% empty) and use Activity Monitor to check for rogue processes.

    Read the following technical specification
    This will tell you what facilities your computer needs to be upgraded to Mountain Lion.
    Pay particular attention to the amount of RAM.  Apple says you need 2GB, most people here would recommend 4GB.
    When you are satisfied you are equipped, you will need to use App store to buy the download ... and away you go.

    Plenty of people, including me, are currently running CC on Mavericks.

  • When i open an mp3 file from a source other than apple, does itunes create it's own file and can I then delete the original mp3?

    when I open a music file from a source other than apple, does itunes create it's own file and can I then delete the original mp3?

    If you use iTunes' default settings then when you add a file to iTunes it places a copy of the file in the iTunes media folder and it leaves the original in place.  The exception is when you drag it to the Automatically Add To iTunes folder.
    It does not convert the file.  You can delete the original if you wish.

  • I currently have Lion, when I upgrade to Mountain Lion, all my apps, music, videos and other files will be erased?

    I currently have Lion, when I upgrade to Mountain Lion, all my apps, music, videos and other files will be erased?

    Lion dropped application support for PowerPC. An OS may drop or change what to use to open a file, not the file.
    Of course CCC is what many have used for 10 yrs now and it is or will be $20 like SuperDuper - commercial.
    Always use something like those in addition to or instead of TimeMachine.

    As Austin Kinsella1 says, it's a good idea to check your program versions.

  • Is the file and apps will lost when upgrade to Mountain Lion?

    I'm currently use lion and tend to upgrade to mountain lion. is it will affect my files and apps after upgrade to it? sorry, i'm a new user of apple product.

    You mustn't lose your apps, but you have to do a backup if the upgrade fails and you can't access to OS. Also, you can check the app compatibility, but if you use Lion, you mustn't have problems with them
