How do I uninstall OS Lion and revert to Snow Leopard

Hi all, I need to use Microsoft Office Mac Version in my work. And OS X Lion don't support that. I am desparate to know how do I unistall the OS X Lion, and revert to Snow Leopard so that I can resume working on my MacBook Pro. Please help.....

MS Office for mac 2004 is indeed incompatible I believe but 2008 onwards isn't. You should consider upgrading your MS Office to be compatible. Apple is not responsible for making 3rd party software compatible with its OS, its the 3rd party developers who updates their softwares and drivers.
You can certainly revert back to Lion BUT it depends what type of machine do you have?Did you purchase Lion as an upgrade?is your machine Lion preinstalled?

How does one un-install Lion and revert to Snow Leopard?

Anyone know how to un-install Lion and revert to Snow Leopard?

Downgrade Lion to Snow Leopard
1. 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.
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area. If it does not say "Verified" then the drive is failing or has failed and will need replacing. SMART info will not be reported on external drives. Otherwise, click on the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID then click on the OK button. Click on the Partition button and wait until the process has completed.
4. Quit DU and return to the installer. Install Snow Leopard.
This will erase the whole drive so be sure to backup your files if you don't have a backup already. If you have performed a TM backup using Lion be aware that you cannot restore from that backup in Snow Leopard. I suggest you make a separate backup using Carbon Copy Cloner 3.4.1.

How do I add Mountain Lion and still keep Snow Leopard for use on specific software

I currently am using OS 10.6.8 which supports Final Cut Studio version 7.5. I do not wish to change my Final Cut work, however I am now developing APPS and need the xcode tools which are only supported on OS 10.7 or higher. Can someone please direct me to any information on how I can set up my Macbook Pro to run both OS systems?

No, you buy & install Mountain Lion on a new partition, leaving the original alone. You will need to reboot from one to the other to use either version of the OS.
As you can see from this I still have Lion on my internal while I'm running Mountain Lion on an external drive - this may also be an option for you?

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.

How do I uninstall mountain lion and reinstall snow leopard

If I had known that I would not be able to use my excel files I would not have purchased OSX Mountain Lion. Is there a way to uninstall mountain lion and reinstall snow leopard?
Thank you,

To get more to the point the answer is the only way to go back to SnowLeopard is if you have a complete backup of your system from before the upgrade.
If you do you would boot off your original SL DVD wipe the disk and install SL and then restore from your SL backups.
Short of that here is no way to go back. But as the others have offered there are other less drastic means to deal with the problem.

I believe you mean to return to Snow Leopard:

If you have Snow Leopard Time Machine backups, do a full system restore per #14 in Time Machine - Frequently Asked Questions. If you have subsequent backups from Lion, you can restore newer items selectively, via the "Star Wars" display, per #15 there, but be careful; some Snow Leopard apps may not work with the Lion files.

HT1923 How do I uninstall itunes 11 and revert to itunes 10?

Hi,
How do I uninstall itunes 11, which I find a chore to use, and revert to itunes 10? Is it possible? Or should I just get on with it?
Thanks
Spudzulyke

The main differences between iTunes 11 and earlier versions are the loss of coverflow and ability to have multiple windows open.
In Windows, you can restore much of the look & feel of iTunes 10.7 with these shortcuts:
ALT to temporarily display the menu bar
CTRL+B to show or hide the menu bar
CTRL+S to show or hide the sidebar
CTRL+/ to show or hide the status bar (won't hide for me on Win XP)
Click the magnifying glass top right and untick Search Entire Library to restore the old search behaviour
Use View > Hide <Media Kind> in the cloud or Edit > Preferences > Store and untick Show iTunes in the cloud purchases to hide the cloud items. The second method eliminates the cloud status column (and may let iTunes start up more quickly)
If you don't like having different coloured background & text in the Album (Grid) view use Edit > Preferences > General and untick Use custom colours for open albums, movies, etc.
With iTunes 11.0.3 and later you can enable artwork in the Songs view from View > Show View Options (CTRL+J) making it more like the old Album List view
View > Show View Options (CTRL+J) also contains options to change the sorting of grid based views
N.b. iOS 7 requires iTunes 11.1 or later. Do not downgrade iTunes if you have already upgraded your devices... Roll back of iOS is not possible.
If you feel the need to roll back to iTunes 10.7 first download a copy of the 32 bit installer or 64 bit installer as appropriate, uninstall iTunes and supporting software, i.e. Apple Application Support & Apple Mobile Device Support. Reboot. Restore the pre-upgrade version of your library database as per the diagram below, then install iTunes 10.7.
See iTunes Folder Watch for a tool to scan the media folder and catch up with any changes made since the backup file was created.

How to uninstall lion and re-install snow leopard

How do I uninstall mountain lion and go back to lion, how do I uninstall mountain lion and go back to lion

Please help!!! I dont like it!

The installer may do squirrelly things in an upgrade like nip and tuck the code, turning Lion into Mountain Lion. The best option is to do a fresh install. Do a Time Machine backup of your files (you can probably exclude the system folder and apps - just download them again from the App Store). Concentrate on your home folder - iTunes files, your library folder, iPhoto library, etc. Re-download Mountain Lion from the App Store. If the installer starts, quit the app. Now go to your Application folder and find the Mountain Lion installer. View the contents of the package and go to Contents:SharedSupport:InstallESD.dmg. Drag the .dmg file to your desktop or someplace else convenient. Next, open Disk Utility and burn the disk image to an 8 GB DVD or flash drive. If you burn it to a flash drive, you may get an error saying the burn failed. If it burned for a while, long enough for the image to actually copy over, ignore it. Reboot your Mac whole holding down the Option key with the flash drive in a USB port or DVD in the drive. You should get the option to boot from that drive. Select the Mountain Lion DVD/USB option to test the boot. You can then either continue the installation or quit the installer until you're ready.
If you purchased Lion from the App Store previously, there doesn't seem to be a way to download Lion within Mountain Lion. You may have a friend with either Lion or a newer Mac with Snow Leopard installed, if so, you may want to login to their App Store, download it, and try to install Lion that way. If you bought your Mac with Lion preinstalled, you won't be able to download Lion at all.

How do you transfer from mini to imac with fire wire if iMac has Lion and mini has snow leopard

My logic board has gone on my mini(intel) and I need to transfer this machine to an iMac(with Lion) how do I do this as it doesn't seem to be working with my disc.My update to Lion was purchased as a download and the only disc I have is snow leopard to reboot.

If your Mac mini has a dead logic board then you will not be able to boot it at all, not even in Target Disk Mode. You would either have to get the logic board repaired, or remove the hard disk and either put it in a disk enclosure or connect it in some other way to the iMac.
The fact that the two Macs ran different versions of OS X is irrelevant, once you have the drive connected to the iMac you can run the Migration utility to migrate the user account and data.

How do I uninstall unwanted aps, games, etc. from Snow Leopard?

I am getting ready to upgrade to Lion and I have several apps that I no longer want on my MacBook Pro OS X 10.6.8. I am used to a PC where you
have to clean it up and get it ready (defrag) for new programs. Boy, I don't miss my pc. Do I need to do this with a Mac? Also, I am concerned about getting the whole program deleted completely. I am not even certain that I downloaded and opened the apps properly, but they worked. I just clicked on the desktop and they opened. I have been reading that some unnecessary files needed to be deleted at that time and not put in the application folder. What do I know?
Thanks for any help.

Uninstalling Software: The Basics
Most OS X applications are completely self-contained "packages" that can be uninstalled by simply dragging the application to the Trash. Applications may create preference files that are stored in the /Home/Library/Preferences/ folder. Although they do nothing once you delete the associated application, they do take up some disk space. If you want you can look for them in the above location and delete them, too.
Some applications may install an uninstaller program that can be used to remove the application. In some cases the uninstaller may be part of the application's installer, and is invoked by clicking on a Customize button that will appear during the install process.
Some applications may install components in the /Home/Library/Applications Support/ folder. You can also check there to see if the application has created a folder. You can also delete the folder that's in the Applications Support folder. Again, they don't do anything but take up disk space once the application is trashed.
Some applications may install a startupitem or a Log In item. Startupitems are usually installed in the /Library/StartupItems/ folder and less often in the /Home/Library/StartupItems/ folder. Log In Items are set in the Accounts preferences. Open System Preferences, click on the Accounts icon, then click on the LogIn Items tab. Locate the item in the list for the application you want to remove and click on the "-" button to delete it from the list.
Some software use startup daemons or agents that are a new feature of the OS. Look for them in /Library/LaunchAgents/ and /Library/LaunchDaemons/ or in /Home/Library/LaunchAgents/.
If an application installs any other files the best way to track them down is to do a Finder search using the application name or the developer name as the search term. Unfortunately Spotlight will not look in certain folders by default. You can modify Spotlight's behavior or use a third-party search utility, Easy Find, instead. Download Easy Find at VersionTracker or MacUpdate.
Some applications install a receipt in the /Library/Receipts/ folder. Usually with the same name as the program or the developer. The item generally has a ".pkg" extension. Be sure you also delete this item as some programs use it to determine if it's already installed.
There are many utilities that can uninstall applications. Here is a selection:
AppZapper
Automaton
Hazel
CleanApp
Yank
SuperPop
Uninstaller
Spring Cleaning
Look for them at VersionTracker or MacUpdate.

In mail in lion and also in snow leopard you were able to click on an incoming email address and select it in spotlight , this feature in mountain lion is now gone , where did it go it was really useful?

I used to use this feature multiples times a day as it was a great way to look up all correspondance that a person had sent through.
