How can I downgrade my Os x Maverick to Os x mountain lion without time machine

downgrade os x maverick to os x mountain lion without time machine back up and disc

To downgrade you have to have a copy of the Mountain Lion installer, download from the Mac App Store but be sure to go to System Preferences > App Store first and uncheck boxes that will automatically install the download.
You will have to erase the hard drive and then install from a saved copy of the installer, saved to a flash drive for instance.
This is going to be a time consuming exercise, so is there a specific reason for wanting to downgrade?

Downgrading from Mavericks to Mountain Lion WITHOUT time machine backup from Mountain Lion.

Hello. I'm one of the unlucky owners of Macbook Retina 15" Mid 2012. I was very satisfied with this computer, everything was great, untill I installed OS X Mavericks. My computer started to have GPU Panics all the time under some "heavier" usage like watching long videos on YouTube. I googled this problem and then I saw that I wasn't the only one, many people had problems after upgrading to Mavericks. I also read that downgrading to Mountain Lion solves the problem, but after the Internet Recovery update, when you are restoring your mac, it restores as Mavericks. I read Apple instruction how to revert os x, but it requires Time Machine backup from Mountain Lion, I already downloaded ML Installer from AppStore but I don't know how to install it.
Greetings,
Mdkn

If you have a Mountain Lion installer application then you can downgrade, but you will have to erase the drive. You should try backing up your Home folder in advance so you could at least restore your data. You will need to reinstall any third-party applications.
Make Your Own Mavericks, Mountain/Lion Installer
After downloading the installer you must first save the Install Mac OS X application. After the installer downloads DO NOT click on the Install button. Go to your Applications folder and make a copy of the installer. Move the copy into your Downloads folder. Now you can click on the Install button. You must do this because the installer deletes itself automatically when it finishes installing.
   2. Get a USB flash drive that is at least 8 GBs. Prep this flash drive as follows:
Open Disk Utility in your Utilities folder.
After DU loads select your flash drive (this is the entry with the mfgr.'s ID and size) from the leftside list. 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.
Select the volume you just created (this is the sub-entry under the drive entry) from the left side list.
Click on the Erase tab in the DU main window.
Set the format type to Mac OS Extended (Journaled.) Click on the Options button, check the button for Zero Data and click on OK to return to the Erase window.
Click on the Erase button. The format process can take up to an hour depending upon the flash drive size.
            3. Use DiskMaker X to put your installer clone onto the USB flash drive.
Wait for the process to complete which will take quite some time.
Use your new installer flash drive to boot the computer. Boot by doing:
Boot Using OPTION key:
1. Restart the computer.
2. Immediately after the chime press and hold down the
      "OPTION" key.
3. Release the key when the boot manager appears.
4. Select the disk icon for the USB flash drive.
5. Click on the arrow button below the icon.
Partition and Format the hard drive:
Select Disk Utility from the main menu and click on the Continue button.
After DU loads select your newly installed 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.
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. Mavericks: Select Reinstall Lion/Mountain Lion, Mavericks and click on the Install button. Be sure to select the correct drive to use if you have more than one.
You will need an active Internet connection.

How can you perform a factory restore on an iMac running mountain lion, without the use of an apple id

Hello!
I am a computer tech working for a computer company. We have an iMac here in the store which a customer needs restored to factory defaults.
I have tried the following:
     - Using 'command + r' to format and reinstall mountain lion (it is requesting an apple id that has purchased the mountain lion OS)
     - Using 'option' on boot up, same seneraio
Is their any other way to perform some kind of equavilent procedure that would ready a iMac for re-selling?
It's almost as though I need to purchase a copy of the operating system that has already come preinstalled on this system.
Im not a mac savy user, maybe it's something simple i am missing. Any help with this would be greatly appreiated! Thanks in advance!

You must have the account credentials for the account that was used to purchase Mountain Lion (this iMac was upgraded) presumably the customer.

Boot the iMac, go to Apple>About This Mac>System Report, post the model identifier here (under hardware, 2nd line down)

Hi guys, recently had the same issue. You require an older version of Airport Utility to configure the older Airport Express. It can be found here.

Mountain Lion causing apps not to work, how can I downgrade to Lion without Time Machine Back-up?

Since installing Mountain Lion, I have found applications that don't work. I want to go back to Mountain Lion, unfortunately I had trouble with my Time Machine back up hard drive a couple days after installing Mountain Lion and I don't have any back up to work from. Tried to go to App Store and redownload Lion from there under purchases, but I got message that said "You can’t upgrade this version of Mac OS X because a newer version is installed."
I have another mac that I can download the Lion install package to and then drag it over to this computer, so the question is, Will I be able to re-install Lion over the upgraded Mountain Lion without any problems?

Can i downgrade my macbookpro (model indentify 11.1) to mountain lion, it comes with maveri

can i downgrade my macbookpro with a last generation of proccessor intel (model indentify 11.1) to mountain lion, it comes with maveric. i want to do this because the software that i work can´t run in maverick

I'm assuming that since you bought a new MBP that you don't have a copy of Mountain Lion? If not, I don't think you can find it on the app store anymore but you may be able to find a bootable disk elsewhere, ie. the apple support pages. If you have a copy of Mountain lion, then you should be in luck.
First, if there are any files you want to save, you will want to copy the individual files to another drive so as to save them. You probably don't want to use time machine for this because not everything is backward compatible between the OS's.
Once you obtain a bootable version of Mountain Lion, do this.
Insert the recovery disc via USB or optical bay. (I think it may HAVE to be a USB stick, 4gb min)
Shut down your computer. Wait for it to power down completely.
Power on your computer while pressing and holding cmd + R.
Once the page loads, Select Disk Utility.
Erase the hard drive.
Shut down computer.
Reboot computer.
After that, wait until progress bar is finished and then you should be able to install Mountain Lion.
Good Luck!

How can I change order of email accounts in Mail on Mountain Lion?

In Mail on Mountain Lion I have only two email accounts, but the wrong one has been set as default (because it was an account I had overlooked and added later). I cannot find how to change the order of the email accounts. One possibility is to delete the non-default account and re-add it, so that it becomes the most recent and thus (presumably) the default, but this would delete all the email messages in that account, which I cannot afford.
It's a great flaming pain to try to remember each email I write to select the second account option, and yet I can find no way to change email account order---not in Mail and not in System Preferences. Dragging them certainly does not work.
Can Apple have really missed this? Is there any solution?

Comfortable with terminal...know how to edit using TextEdit:
Open up a Terminal and use the following commands to change your Mail.app preferences file to an XML format – the default format is binary, and you can't edit this.
cd ~/Library/Preferences
plutil -convert xml1 com.apple.mail.plist
Then, open this file com.apple.mail.plist with a text editor of your choice, preferably one that highlights XML syntax, but you can also use TextEdit:
open -a "TextEdit" com.apple.mail.plist
Now, look for the key called MailAccounts. It's value is an array, with dict children. Here, you'll find all your mail accounts in the order they were created in.
You can now manually move these dict children around. Save the XML file and reopen Mail. Now, your Mail account order will be changed.

How can you tell which files have backed up to external hard drive using Time Machine?

Hello Mac Users,
I have Macbook Pro (early 2011) and recently purchased a WD My Passport for Mac external HD. I have completed a back up using Time Machine, however how do I tell what files actually were backed up? I have a ton of audio, documents and photos that I would like on there. Its a 2 TB HD, my memory is 750 GB... Im using 632. At end of back up, the drive still had 1.88 TB left. Any help would be appreciated! Thanks

This procedure is a diagnostic test. It makes no changes to your data.
Please triple-click anywhere in the line below on this page to select it:
tmutil compare | open -ef
Copy the selected text to the Clipboard by pressing the key combination command-C.
Launch the built-in Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad and start typing the name.
Paste into the Terminal window by pressing command-V. I've tested these instructions only with the Safari web browser. If you use another browser, you may have to press the return key after pasting.
The command may take several minutes to run. Wait for a new line ending in a dollar sign ($) to appear below what you entered.
A TextEdit window will open with the output of the command. Don't post all the output; just read it yourself. Each line that begins with a plus sign (“+”) represents a file that has been added to the source volume since the last snapshot was taken. These files have not been backed up yet.
Each line that begins with an exclamation point (“!”) represents a file that has changed on the source volume. These files have been backed up, but not in their present state.
Each line that begins with a minus sign (“-“) represents a file that has been removed from the source volume.
Files that you’ve excluded from backup, or that are excluded automatically, are ignored.
At the end of the output, you’ll get some lines like the following:
Added:
Removed:
Changed:
These lines show the total amount of data added, removed, or changed on the source(s) since the last snapshot.
Caution: Under some conditions, tmutil may falsely flag files as not having been backed up when in fact they have been. It can be confused by multi-linked files, or by files with a modification date earlier than the one in the snapshot. This will not be an issue for most users. If the results of the above procedure surprise you, inspect your snapshots directly.

How can I get Mac Mini to accept bootable installers for Mountain Lion ? They work fine on MB-Pro

I've had a Mac Mini (late 2012) for the past week and need to do a complete reinstall to get rid of very mucked up Server.app settings that I can't get rid of even though I uninstalled Server.app and what I thought were all of its Library files. I need to get the Mac Mini back to pristine, factory default to start over. Then I'll be able to put Server.app into a VM so I can trash it if need be without mucking up the rest of my system.
I have both a bootable recovery partition on an external hard drive (My Book firewire) and a USB bootable installer with a fresh edition of Mountain Lion. I know the USB installer works just fine because I used it to do a clean install of my MacBook-Pro just last night. Went like a charm.
When I start up the Mac Mini with the option key held down, everything seems fine -- I see both the USB drive and the My Book's 2 volumes (1 for data, 1 for the Recovery partition). But when I select either the USB drive or the My Book Recovery partition as the start-up drive, I get a screen with a circle with a line across (the no-entry traffic sign), with no way to go back or forward. So the computer has to be rebooted.
Any suggestions as to how to get the Mac Mini to recognize bootable installers that MacBooks are able to see?

Late 2012 Mac mini uses a special Mountain Lion version that it's only compatible with this Mac and you can only get on Internet Recovery because it's not available in the App Store. If you want to reinstall Mountain Lion, press Command, Option and R keys while your computer is starting

How can I update from Os X 10.6.8 to Mountain Lion 10.8.4?

I am trying to update my Mac from OS X 10.6.8 to Mountain Lion 10.8.4. I have read online that I can no longer buy Mountain Lion from the App Store, and that I must purchase Mac X Maverick instead, but cannot find that on the App Store either. All I want to use this eBay computer for is for iTunes radio, which needs OS X 10.7 or greater. Could someone point me in the right direction for updating? I'm a grandma, fer Pete's sake! : ) Thanks to anyone who can help me.

Open the Mac App Store and try downloading Yosemite. If you get told it's incompatible, choose About this Mac from the Apple menu, check if the computer has at least a Xeon or Core 2 Duo(not Core Duo) CPU and 2GB of RAM, and if it does, click here and order a download code for Lion 10.7.
Back up your data and check your applications for compatibility before upgrading. In particular, Mac OS X 10.7 and newer don't support PowerPC programs such as versions of Microsoft Office prior to 2008.

How can I manage an older airport express base station with Mountain Lion?

This version of AirPort Utility doesn't support this base station. Use AirPort Utility 5.6 to configure or manage this base station. AirPort Utility 5.6 is available at AirPort Service and Support."
I tried to install AirPort Utility 5.6 on my Mac OSX 10.8 Mac Book and it will not allow me to. How do I manage my "older" airport?

The 5.6 version can be installed but it does take an alternative route to do so. For example, you can use a utility like Pacifist to first extract the utility, and then, move it to the Utilities folder. Once "installed" by this method, it runs just fine on Mountain Lion.
