Can I uninstall mountain lion without loosing the content on my hard drive?

I hae just installed mountain lion and now I can not use my Adobe programs - note saying it can not run power PC programs. I am on a deadline and I MUST get back to the files I was working on before I did this.
I need to know if I can unistall without loosing all the files I was working on before.

Hi Cate,
Like John says , it is better to upgrade to latest Adobe as they are 64Bit based so they would perform much better on your Mac.
It can make proper use of your RAMS and graphic card.
good luck..

Can I uninstall and install without loosing play lists

Can I uninstall and install without loosing play lists

Your iTunes folder (normally under ~/Music/iTunes) contains files that tell iTunes what you have in your library, playlists, genres, ...These database files have extensions of .itl and .xml. Deeper in the iTunes folder you have the actual media (movies, songs, tv shows).
Uninstalling iTunes and then reinstalling iTunes should not impact your iTunes library. It will change iTunes settings like window size, if you have the sidebar turned on, and the like. I do recommend you have a backup of your iTunes folder but at least save copies of your .itl and .xml files.
Your question is a bit cryptic so I'm guessing at your actual question. Good luck.

I can't download mountain lion, I get the following message "could not complete your purchase, can't verify the file, it may be damaged or unsigned" ? what do i have to do ?

The only thing that worked for me was to boot in safe mode.
Power down. Then press power button and hold 'shift' key until grey screen with progress bar appears... Once booted and logged in just open safari and browse to applestore.
No trouble at all once I did this.
Reminder: create full backup before you upgrade OS
Hope it helps.

Do you get this window when you hold down the Command+Option keys and launch iPhoto?
If not then you're not holding down both keys long enough.

Can I combine the contents of 2 hard drives in to 1 drive?

I have a new 1TB hard drive that came with applications pre installed. I'd like keep its contents and add the contents from my recent Time Machine backup. Some of the applications are redundant but that's OK with me. I just don't want to lose the contents on either hard drive. My initial hard drive is 256GB and has Mavericks, MS Office 2011, iTunes library and a buch of other apps and files and photos. The new drive is 1TB and is pre loaded with a buch of cool apps. Some are dupes like MS Office 2011 and the typical Macbook apps, iTunes etc. but I want to add the contents from my 256GB drive to the contents of my 1TB drive without losing anything. Do I used "Install from backup disk" in Time Machine?
I backed up the 256GB drive and installed the 1TB drive just waiting to hear how to move the contents ove without wiping the contents of the 1TB out.
Thanks!

I went old school and copied apps, documents and photos from the old drive to the new one.

How can I buy Mountain Lion without download etc. Just associate with apple id to do reinstall on Mountain Lion Macbook

I am trying to reinstall a Macbook Pro that had previously been upgraded to Mountain Lion x by the old owner. When I try to reinstall I need to input an apple ID that has purchased Mountain Lion. My ID hasn't. How can I either revert back to the original OS or associate Lion with my apple ID. I have happy to pay the $19.95 just cannot find where.

You can purchase Mountain Lion using your Apple ID at the App Store. You cannot use the version installed by the old owner. In fact it should not have even been installed by the old owner when he sold it.
You can install Snow Leopard and update it to 10.6.8 in order to purchase Mountain Lion under your Apple ID.
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.
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.

How do I uninstall Mountain Lion and restore the prior program?

I am having too much trouble with my iMac since purchasing and downloading Mountain Lion. Can anyone give me simple directions on how to uninstall the OS and revert back to the prior program. I am not a computer savant! thanks

Unfortunately, installing a previous version of OS X is not simple. It might be easier to try to address the issues you're having with 10.8 - if you can explain what's happening, we can try to help.

Can I uninstall Mountain Lion? It's VERY SLOW!

I installed the Mountain Lion OS 10.8.2 and have nothing but slow slow slow page loading and slow painting of photos. It was bad enough that I lost my calendar data but the slow operating system drives me nuts. If I wanted slow I could've kept a pc. Any advice? Can I get rid of this OS and get the old one back, please?

You are right, Thomas A. Reed.
It appears that my speed problem was not with Mountain Lion but was with my (new) wireless router. (The old one had died.)
Now that I'm connected via an ethernet cable, my speed is WAY faster. When I go to my next one-to-one appointment I'll get an Apple wireless router -- perhaps one with an external hard drive to use with Time Machine.
Thank you!

Can I get Mountain Lion without downloading it

Is Mountain Lion available in other forms than downloading it??

Search for something like "Mountain Lion install disc" and you will find ways of putting the installer on a double sided DVD or a USB stick (would nee about an 8Gb one). Initially you download, then halt the installer when it starts up, follow a few steps and create a permanent copy of it on optical media or USB memory stick.

Can I Install Mountain Lion without reinstalling Adobe CS4?

Adobe CS4 edu version is difficult to get authorized and set up with seriel numbers.
I won't install Mountain Lion, until I hear that it shouldn't step on My Adobe CS4 Creative Suite 4 Design Premium.
Has anyone installed the new OS successfully?

I installed with CS5 on my hard drive, I did not have any issues, but I did backup first and suggest that you do as well.

I need to re-download Mac OS X Mountain Lion to put the installer onto a flash drive to perform a clean re-install, Will I need to buy the software again?

It says on the Mac App Store "You have already got OS X Mountain Lion on your computer, would you still like to download?"
Will it charge me £13. again if i choose ok???

Not if you download it from your Purchases page. Click on Purchase icon in the App Store toolbar.
BTW, you don't need to put Mountain Lion on a flash drive for a clean install:
Install or Reinstall Lion/Mountain Lion 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 Lion: Select Reinstall Lion/Mountain Lion 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.

Mountain Lion is missing, after installing an external hard drive and Carbon Copy Clone.

I have a mid-2007 desktop iMac Model MA877LL, 2.4 ghz/1gb/320gb, with 4 GB memory, upgraded to Mountain Lion 9/7/2012 at an Apple store (now 10.8.5). I just installed a new external hard drive Fantom Drive 1T G-Force Mega Disk Firewire 800, then installed Carbon Copy Clone successfully. However, I could not get the clone to boot from the backup volume. Mountain Lion showed in both Macintosh HD and External Hard Drive at that point. After working through many steps with CCC, trying to get it to boot, the final suggestion was to try installing Mountain Lion onto the backup disk via the Mac App Store Installer. As my Mountain Lion was installed at an Apple store, there's no record of it on line and I can't find an installer, although I've been doing updates as they're issued. Per article, "OS X: Installing OS X on an external volume", I erased and reformatted the storage device. Now, checking my Macintosh HD, Mountain Lion is gone. How do I get it back?

Are you saying that your internal HD doesn't have an operating system on it either, meaning you can't boot your iMac at all? Or that the external was also named "Macintosh HD" in which case, having been erased and reformatted (hopefully with a GUID partition table), you'll need to clone your internal to it once again.

I can't access my playlist without being connected to my external hard drive

I can't access my playlist without being hooked up to the external hard drive. With the external hard drive connected I can sync it on my iPhone and iPad but won't do it for the computer

If you mean photo albums that were synced from your computer then no, then can only be deleted by re-connecting to your computer's iTunes, de-selecting them on the Photos tab and re-syncing.
If you mean music albums then yes, you can press and hold an album on the album selection screen in the Music app, and after a second or two you should get an 'x' on it - tap that and it should be deleted.

How can I tell what is using up the space on my hard drive?

My computer has been messing up for a while, giving me the message "startup disc almost full". I only have 4 gb free space now, after throwing all my photos and music onto external drive. What is making my disc so full? All the rest of my files are text? How can I figure out what is taking up so much space? Thanks

Moving iTunes music is more involved than a simple
drag and drop affair; you would be making copies on
some other media, but could be leaving duplicates or
originals on the hard drive in the process. Same with
images and iPhoto derived items. There are some
Apple Support documents on how to manage these.
The user folder has things in it you have installed;
generally your saved items would be found in there.
