How can I uninstall Mountain Lion?

Unfortunately, I've downloaded and installed ML yesterday and now my safari is very slow in opening pages and I can not open iPhoto.  I wish to revert back to the Lion OS.  

There is an update to iPhoto in the App Store and and here: http://support.apple.com/kb/DL1562. There a number of reasons Safari might be sluggish. Are you running Anti-virus software? What extensions if ant are you running. What plugins have you added to safari if any?

  • How can I uninstall Mountain Lion and go back Lion?

    I have tried everything. My MacBook Pro is just not the same since ML. I want to get rid of it and go back Lion. What is the easiest way to do so?

    Clearing cache is a poor thing to do to improve system performance.
    In fact, when you clear cache you actually slow your system down until cache is reloading again.
    Yes, it is true cache can get corrupt and have to be cleared. This happens so infrequently that it is almost never a required solution unless you have problems that are specific to corrupt cache.
    By the way why are you replying to my post when in fact your comments have nothing to do with my post at all.

  • I do not have a high speed internet connection. How can I get Mountain Lion on a disk for install?

    I do not have a high speed internet connection. How can I get Mountain Lion on a disk for install on my 24" Imac?

    As long as you use your Apple ID to purchase it, I don't see why they wouldn't let you download the installer on one of their Macs and put it on a pocket drive.
    Or, a friend with a high speed connection?
    I agree with you about the delivery method, just trying to help you get what you want.

  • How can i get mountain lion reinstalled if my mac says apple id never purchased? hd failed 2 wks after wty expired, I am the original owner, i have done command-r

    how can i get mountain lion reinstalled if my mac says apple id never purchased? hd failed 2 wks after wty expired, I am the original owner, put another hd in, done command-r & sys reinstalled, but it wanted to update & now am stuck. I don't mind paying for mountain lion; it is too far to get to an apple store. but, i only have one mac, so i cannot download with another mac. lots of other apple, but only one mac.

    You will need to do a network recovery:
    Install Lion/Mountain Lion on a New HDD/SDD
    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 Internet Recovery HD:
    Restart the computer and after the chime press and hold down the COMMAND-OPTION- R keys until a globe appears on the screen. Wait patiently - 15-20 minutes - until the Recovery main menu appears.
    Partition and Format the hard drive:
    1. Select Disk Utility from the main menu and click on the Continue button.
    2. After DU loads select your external hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. 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. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the process has completed. Quit DU and return to the main menu.
    Reinstall Lion/Mountain Lion: Select Reinstall Lion/Mountain Lion and click on the Install button. Be sure to select the correct drive to use if you have more than one.
    Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.

  • HT4854 How can I load Mountain Lion to multiple Macs

    How can I load Mountain Lion to multiple Macs without downloading the huge 4Gb file to each machine?

    I've never done that, but I don't see why it wouldn't. There is no verification or authentication keys in the installer.
    If you need 20+ licenses*, then you might take a look at the volume licensing: http://www.apple.com/mac/volume-licensing/
    It describes the same process I described.
    * I think 20 is the minimum. Not sure, though.

  • How can I reinstall Mountain Lion on new hard drive?

    I've had to install a new hard drive as old one was failing.
    Have loaded Snow Leopard from disc onto the new drive but can't install Mountain Lion which I was running prior to drive failure; very frustrated.
    Have tried several options.
    1. Tried to reboot from OS X Utilities but whenever I restart, holding the cmd + R keys, I can only ever get the standard screen. I've tried pressing keys early in restart, later in restart, keys on either side of the keyboard, cmd + alt/option + R but still can't get to the OS X Utilities.
    2. Having given up on 1 I've tried to download ML from my purchase history in iTunes. I can see the purchase recorded but there appears to be no way to get to a reload option - at least not in the iTunes loaded from Snow Leopard
    3. I tried downloading ML updates, hoping that might allow me to bypass 1 and 2. The download wasn't recognised by my machine.
    4. I've be willing to just buy the **** OS again from scratch but iTunes won't allow me to do that either, at least not using my current Apple ID.
    Does anyone have any bright ideas? I hate bloody computers.

    Thanks,

    How old is your Mac, if it came with 10.6 installed it is too old to have Internet Recovery (command-option-R) And as it has a new hard drive you won't be able to use Recovery (command-R) either until a new copy of Mountain Lion is installed and ceates a recovery partition on the drive.

  • 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.

  • 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 can I stop Mountain Lion from writing savedSate?

    Hi everyone,
    I have an SSD (used as the system disk) in my iMac, and after noticing that its lifespan (according to S.M.A.R.T.) has ticked down a bit, I started looking at what's writing to the system disk, using iostat, iotop, and fs_usage.
    What I discovered is that, even though I have Resume turned off (by checking "Close windows when quitting an application"), Mountain Lion is still writing huge amounts of data to the *savedState folders in ~/Library/Saved Application State, for each application I have open. The only difference with Resume turned off is that it removes the *savedState folder for each app when I quit that app.
    Since I use this iMac for work, I typically have quite a few applications open for long periods of time. According to iostat, this is causing over 1 gigabyte of data per hour to be written to savedState. That's 10-12GB in a typical day, not including data I actually write to the drive as I work! Needless to say, this is hammering my SSD and is probably what is decreasing its lifetime.
    I've spent a couple of hours googling this problem, and though I've found lots of ways to turn off Resume both globally and per-application, none of them prevent Mountain Lion from continuing to write all this Resume data to the *savedData folders. Does anyone know how to completely turn off Resume and stop all this unnecessary disk I/O?
    Thanks!

    YOu can get it stop by going to ~/Library/Saved Application State/TextEdit (by example) and delete that file…
    (note that the User Library is hidden - one way to get there is to go to your Finder "Go" menu hold the option key to choose "Library")
    You can also delete all Saved Application State files
    Or use Terminal to turn off Resume globally...
    chflags uchg ~/Library/"Saved Application State"
    Press return
    Or
    defaults write -g ApplePersistence -bool no

  • 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.
         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
             6. Mac Pro (Early 2008 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?

  • How can I reinstall Mountain Lion (already bought before) after I restore my MacBook unibody (restores it to snow leopard)?

    Originally I had upgraded my MacBook unibody to mountain and used time machine to back up my data. I then wanted to restore my MacBook so I did but it restored my MacBook to snow leopard. After restoring to an old time machine backup some of the apps aren't compatible because they require mountain lion but my system got restored to snow leopard. How can I reinstall my already purchased mountain lion if snow leopard doesn't have an App Store?

    10.6 Snow Leopard will get the App Store when you update it to 10.6.8. Download the 10.6.8 combo updater to bring it up to 10.6.8. http://support.apple.com/kb/DL1399
