Will upgrading to mountain lion delete any of my programs?

i currently run lion..will all my files, apps, downloads, etc be intact after the upgrade?

Yes, they should not be distrubed. However, it's always wise to have a backup.

Will upgrading to Mountain Lion delete MS Office?

I have MS Office installed on Lion OSX and I am really worried about what will happen once I upgrade to Mountain Lion. Will I lose the installation? Will I have to reinstall from the disc? Or will office survive the upgrade and appear in Mountain Lion? I lost my disc a long time ago. I have a 2011 MacBook Pro.

Yes it is compatible so with will not delete it or render it unusable.
See this article to make sure you have 2008 or later.

Will upgrading to Mountain Lion from Lion make my Lion Time Machine Backups unusable?

I had a situation where when I upraded to Lion from Snow Leopard, my Time Machine Backups became unusable. It says that the Backups were not compatible and it was really frustrating because I had to delete my backups from Snow Leopard and re-backup from my Mac with the newly installed Lion.
Will this happen if I upgrade to Mountain Lion from Lion? Has anyone had trouble from this upgrade to Mountain Lion. Has your Time Machine backups been working fine with the new operating system?
Thanks!!

Will upgrading to Mountain Lion erase all my files? And can't I only backup my home folder from Time Machine anyways? As long as I don't use Migration Assistant to restore the System files.
But yeah, will upgrading to Mountain Lion from Lion erase all my files and accounts?
Thanks!!

When I create a new mailbox, it does not appear in alphabetial order. It appears at the bottom and I have to manipulate it to get it in its proper place. This apparently started when I upgraded to Mountain Lion. Any ideas?

Do you know why new mailboxes I create do not appear in alphabetical order? They appear below all other mailboxes and I have to manipulate them into their proper place. This apparently started when I upgraded to Mountain Lion. Any help would be much appreciated, as it's annoying and time consuming.

Will upgrading to mountain lion format my mac

Hi, Mountain Lion has finally been released, I need to know will upgrading to mountain lion format my hard drive, or will it ask me if I want to format or just replace mounatin lion with Snow Leopard, thanks.

It will replace Snow Leopard with Mountain Lion. You won't be asked about erasing.
However, you should make sure your backups are updated, just in case something goes wrong.

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!

Mavericks upgrade from Mountain Lion deletes all user accounts

This is a lesson for upgrading too early (and too eagerly).
Today I tried the Mavericks upgrade from Mountain Lion on my 2007 Macbook Pro, after going through all the pre-installation/pre-upgrade checklists.
I don't think I have gone from a very high to a down low in such a short space of time. I really wanted to move on from Mountain Lion and when the installer finished the upgrade to Mavericks and re-started my MBP, I was super excited. When the restart completed and I was presented with the login prompt, I tried entering my user name and password. First time, it shaked on the password... OK, you'd think that is a typo. Re-entering the password... same thing.
You can imagine what ensued. After entering my password v-e-r-y slowly many times, I started realising that something went very VERY wrong.
Just for information, I used two different user accounts on my MBP under Mountain Lion. The one account had administrative priviledges and was only used for installing applications and a few other administrative tasks. Then I have a second personal account, which does not have administrative priviledges and is the account I use daily for Mail, Safari, iTunes, programming etc.
None of those accounts worked under Mountain Lion. Basically, there is no way in.
I then proceeded to boot with the startup option Cmd + S (command-line access). Once that was completed, I was in as root and checked the /etc/passwd. None of the user accounts were there. I was only able to find two user accounts: root and nobody; and a long list of user account that started with an underscore (I think these are some sort of esoteric user accounts). So, it appears that the Mavericks upgrade did not accurately bring over the user account information from my Mountail Lion installation.
Then, I went into the /Users directory and there I could see the home directories for all the users as they were defined under Mountain Lion. The contents were intact too.
It seems to me that the Mavericks upgrade from my Mountain Lion forgot to bring over the user accounts but it did preserve the contents of all the users' home directories.
Unless anyone can spot some sort of user error here (please let me know), I am heading back to Mountain Lion pretty swiftly. Otherwise, I suspect there is a bug in the Mavericks installer.
Any assistance is appreciated.

The reason this occurred is a mystery and has not been commonly reported. Consider the following. It may or may not help. You should probably print these instructions before proceeding.
Boot Single User mode again and do the following:
(You can skip the first step. It will check your boot volume for errors and correct what it can. If there were errors the installer should not have proceeded, but the possibility exists that directory corruption may have occurred during installation. That seems unlikely to me but could explain what went wrong.)
In Single User Mode:
At the :/ root# prompt, type fsck -fy and press Return or Enter. It will take a few moments to complete. If you are concerned that nothing is happening just press the Return key until you see the :/ root# prompt again.
Once the disk check is complete and the prompt returns, type mount -uw / and press Return / Enter.
Type launchctl load /System/Library/LaunchDaemons/com.apple.opendirectoryd.plist and press Enter. If you get an error message you may ignore it.
Type ls /Users and press Enter. All of the usernames on the computer will be listed, which is helpful if you don’t know or remember what these are.
Type dscl . passwd /Users/username password while replacing username with one of the users displayed in the previous step and replacing password with the new password of your choice. Press Enter. You will likely get an error message about a file or directory not being found. You may ignore this.
Type reboot and press Enter.

Hi all. I have upgraded to 10.6.8 Snow Leopard on my Mac Pro but still cannot connect to App store to upgrade to Mountain Lion. Any advice?

Hi all, I have upgraded to 10.6.8 Snow leopard on my Mac Pro but still cannot connect to App store.

Reinstall OS X without erasing the drive
Do the following:
1. Repair the Hard Drive and Permissions
Boot from your Snow Leopard Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. 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 installer.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
2. Reinstall Snow Leopard
If the drive is OK then quit DU and return to the installer. Proceed with reinstalling OS X. Note that the Snow Leopard installer will not erase your drive or disturb your files. After installing a fresh copy of OS X the installer will move your Home folder, third-party applications, support items, and network preferences into the newly installed system.
Download and install the Mac OS X 10.6.8 Update Combo v1.1.

I have a macbook, 2Ghz 10.5.8 which is running out of room. Should I add all memory I can and will upgrading to mountain Lion use that all up before i even begin?

I have a macbook using 10.5.8, 2 Gb memory which is running out of room. I use it mostly for photos/videos. How much memory can i add and when i upgrade through snow leopard to mountain lion what will it cost andwill that use up all the newly added memory?

You can put in any 2.5" form factor SATA drive that is 9.5mm or less in height. For RAM we need to know whether you have the 2.0 Ghz or 2.13 Ghz processor model 5.2 MacBook. The model 5,2 (Early 2009, 2.0GHz Model Only) can use 6gb of 200 pin 667mhz PC2-5300 RAM. The model 5,2 (Mid 2009, 2.13GHz Model Only) can use 6gb of 200 pin 800mhz PC2-6400 RAM.
For a new hard drive try Newegg.com http://www.newegg.com/Store/SubCategory.aspx?SubCategory=380&name=Laptop-Hard-Dr ives&Order=PRICE
Or OWC for regular hard drives and SSDs http://eshop.macsales.com/shop/hard-drives/2.5-Notebook/
Here are instructions on replacing the hard drive in a MacBook with a removable battery. http://creativemac.digitalmedianet.com/articles/viewarticle.jsp?id=45088
To transfer your current hard drive I like the free application SuperDuper. It makes a bootable copy of everything on your hard drive http://www.shirt-pocket.com/SuperDuper/SuperDuperDescription.html You'll need a cheap SATA external hard drive case. Put the new drive in the case then format and partition the new drive and clone your old drive to the new one. Check that it's set up right by booting up from the external drive. Then replace your old hard drive with the new one and put your old one in the external case.
Here's a cheap SATA external hard drive case on Amazon http://www.amazon.com/Vantec-NexStar-2-5-Inch-External-Enclosure/dp/B002JQNXZC/r ef=pd_cp_pc_0
If you don’t have the tools to open up the MacBook OWC has a set for $5

Will updating to Mountain Lion delete files?

I updated one Mac and a folder full of files on my desktop was deleted in the installation of Mountain Lion. Was this user error or will it happen again?

Welcome to the Apple Support Communities
You won't lose data but you must make a backup because things like losing folders can happen during the Mac OS X upgrade. I recommend you to buy an external drive, create two volumes on it and use one for Time Machine and the other for Carbon Copy Cloner

Will upgrading to mountain lion mess up my both camp partition?

I was just getting ready to update to mountain lion and I was wondering if it would delete my windows partition?

It shouldn't. But we are taking about computers and anything can happen.

When upgrading to mountain lion will it delete all my files?

Will an upgrade to mountain lion delete all my files so as to lose data or will my existing files be saved?

That's the difference between doing an upgrade or a fresh install. Mac OS 10.6 or .7 can be upgraded or even reinstalled over the top of the existing OS without affecting the user folder which contains all your documents, pictures, music, etc.
In order to do a fresh install you would have to used Disk Utility to wipe the drive before you do the installation.

How to correct battery drainage problem after upgrade to mountain lion

My macbook pro battery drains very fast, just used 3% as I am entering this question. This rapid battery drain started after upgrade to mountain lion. Any advice?

This appears to be a problem that's affecting a number of users and has been widely reported. My guess is you're going to have to wait till they do a software update.
There's general tips for conserving battery power on my page here that might ameliorate matters in the meantime:

Can I upgrade to Mountain Lion with Boot Camp windows 7?

Can I upgrade my mac book pro to Mountain Lion when I have Boot Camp Windows 7?

Welcome to the Apple Support Communities
You can upgrade to Mountain Lion without any problem, but I recommend you to make a backup before upgrading. Also, after upgrading OS X, I recommend you to download the most recent Boot Camp drivers on Boot Camp Assistant and install the drivers on Windows

Will upgrading to a new OS like Lion or Mountain Lion delete my previous files on my computer? Will I have to back up my files with a hard drive first?

Upgrades do not delete your personal files in the Home folder. But any installation can go bad, so it would be wise to backup your current system to an external hard drive.
Upgrade Paths to Snow Leopard, Lion, and/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 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 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 iCloud services; 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) - Model Identifier 7,1 or later
         2. MacBook (Late 2008 Aluminum, or Early 2009 or newer) - Model Identifier 5,1 or later
         3. MacBook Pro (Mid/Late 2007 or newer) - Model Identifier 3,1 or later
         4. MacBook Air (Late 2008 or newer) - Model Identifier 2,1 or later
         5. Mac mini (Early 2009 or newer) - Model Identifier 3,1 or later

         7. Xserve (Early 2009) - Model Identifier 3,1 or later
To find the model identifier open System Profiler in the Utilities folder. It's displayed in the panel on the right.
Are my applications compatible?
         See App Compatibility Table - RoaringApps.
