Is possible to re-install Mountain Lion after Mavericks issues?

My mac became vary unstable after upgrade. Tech support was helpful but there is more issues now then before. They had me safe mode to check any programs that cause boot failure, safe reair and then reinstall new operating system. Now when it boots Finder goes on a tangent. Keeps asking about do you want to quit last program. All programs that are on the Mac came from the App store. The Mac is 2012 model that ran flawless until upgrade.If I revert to Mountain Lion, will I loose anything that was install earlier? And one other thing, I Cloud wants to be involved in everthing.

To completely restore your system from a Time Machine backup boot OS X Recovery by holding the ⌘ and r keys (two fingers) while you start your Mac.
Once the Mac OS X Utilities screen appears, select Restore from Time Machine Backup.
Select the TM backup of your Mountain Lion system prior to upgrading - their backup dates and OS X versions will appear, so you will be looking for the most recent backup of your system when it was running OS X version 10.8.5.
When it completes, your Mac will restart and your previous system state will have been restored.

  • Is it possible ro clean install Mountain Lion over Mavericks on a brand new mac mini

    Is it possible to "clean Install" mountain lion over mavericks on a brand new mac mini

    Actually evrything I can find states that the last mini to run SL was 2010.
    It appears that the 2012 mini's shipped with Mountain Lion and later Mavericks. Link
    Also why would the OP need a bootable SL installation media when they want to install ML?

  • How to reinstall Mountain Lion after Mavericks OS has been installed without using the time machine?

    Hi, I upgraded to Maverics a few weeks ago, and since than my computer has been very slow. It NEVER happened before. Now, I want to go back to Mountain Lion, but I didn't back up my computer with the time machine. I'd appreciate if anyone could tell me how to reinstall Mountain Lion again over Maverics? Thanks a lot for your help!

    You will need either a bootable flash drive with Mountain Lion to install, if you have one, or reinstall Snow Leopard if your computer can boot Snow Leopard. Or you can use Internet Recovery to reinstall the original version of OS X that came with the computer. In any event you will have to repartition and reformat the drive.
    Install Mavericks, 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. 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.
    Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.

  • How do I use Disk Utility to help install Mountain Lion after many failed attempts?

    I tried to install Mountain Lion from an App onto my MacBook.
    First it said that my disk was damaged to i tried to repair it.
    Didn't work.
    Then it said I didn't have enough room to install Mountain Lion.
    Then I tried to restore Lion.
    Didn't work.
    Then someone suggested I reset my PRAM.
    Tried that, and now I am stuck.
    I can't restore any of my backups from timeline.
    I can't reinstall OSX because my drive is now locked.
    And I don't know how to use Disk Utility to solve this problem!
    Any suggestions welcome... I'm in way deeper than I understand and feel like anything I do is making this worse!

    I gather that your computer is in a less than satisfactory state, so the process below will basically start you from scratch, but you shouldn't lose anything.
    Okay, can you inspect the Time Machine Backups with the Finder? About two or so folders down you should start seeing your system files. Assuming all your files are present.
    Important^
    You probably have an installation disk that came with your macBook.  Boot from that CD and install from the CD.
    Run the verify disk utilites and repair utilities if necessary.
    You may want to erase your disk from the CD's disk utility. This will erase your Hard Drive (make sure you do not erase your backups, as that would be very bad).
    Once the installation is complete, run all system updates. Either look through your backup and find the Mountain lion installation app, or download it from the app store again. 
    Run the ML installtion app.
    Once everything is up and running, move all files and folders you want from your TM backups and you should be good to go.

  • How do I install mountain lion over maverick

    how do I install mountain lion over maverick

    Before the install
    Ensure your data (at least all Home folders) is backed up before you install. Hard disks can fail at any time so it is important to regularly backup to an external disk with Time Machine or a third party alternative. Inexperienced users should follow Apple's install advice but experienced users may prefer to do a clean install.

    Upgrade to Leopard
    Those wishing to upgrade to Leopard should be aware that install disks can be expensive. Details: http://lowendmac.com/deals/best-os-x-leopard-prices.html Standard Leopard installers impose several hardware limitations including speed and RAM size but all these restrictions can be overcome. Google for details. Leopard works well at 500 MHz with 1 GB of RAM and many happy users have less than this.
    Upgrade beyond Leopard
    OSs beyond OS X 10.5.8 require an Intel processor. If in doubt click the apple at the top left of your screen and select 'About this Mac'. This will give you your OS number. Then click 'More Info' to see which processor you have. If it says PowerPC you cannot upgrade to Snow Leopard and above. If you have an Intel Mac it is well worth upgrading to Snow Leopard now and then considering other options after that. You can buy Snow Leopard here: http://store.apple.com/us/product/MC573Z/A

  • Can I install Mountain Lion and Mavericks on same computer

    Stupidly I installed Mavericks over Mountain Lion without checking whether Quark XPress 9.5.3.1 would work with Mavericks.
    It won't.
    I have re downloaded Mountain Lion and need to know whether I can run both on same computer - and how to do that - any help appreciated.
    Thanks.

    Sure you can. Erase one of your partitions and install the OS of your choice on it. You can have as many operating systems on a Mac as you want. Use Startup Manager to select the OS you want to boot. Virtualization software is another option.
    Both the Mavericks and Mountain Lion installers will permit you to select the partition on which it is to be installed.
    If you don't tell us the errors that resulted from using Lion Disk Maker no one can begin to guess the reason, but no matter, you don't need the USB installer. Just use the App Store.
    You can save the installer anywhere you like to use as often as you wish, so you don't have to download it each time.
    It looks like this
    You have to copy it before running the installer because the installer conveniently erases the 5+ GB file after the installer is finished with it.

    What can I do?

    You downloaded it from where, how? You need Snow Leopard, 10.6.8 (or at least 10.6.7) to purchase the DL from the App Store. Sounds like it might have been a corrupted, pirated and illegal copy, if you got it from 10.5.
    Btw, you will need more than the 2GB RAM you have. You need to max that out.

  • Unable to install Mountain lion after defense grade erase

    Hello All,
    I just sold my 13-inc macbook pro on eBay. As I am paranoid about my privacy, I decided to do a "defense-grade" erase. It took 10 hours after doing a 7 pass process. However, I am unable to install anything on it (Mountain Lion, Lion, Ubuntu). When I try to install Mac OSX I get the error, "Error installing OS X, try reinstalling".  Huh??
    Please let me know what I should do. Can I not install anymore? Should I get a new one?
    Thanks,
    Singlebinary

    Here's what I did:
    Plugged in my USB drive and started the computer with the option key pressed. I get one choice "Install OS X" which is from my USB drive. After I got an error message, I can cancelled it and under tools selected "Disk Utility". I then selected one partition and the default P table of GUID. So, this has already been done to the drive.
    There is no option to select "Reinstall Mac OS X". All I have is the following:
    OS X Installer, File, Edit, Utilities, Window.
    Under Utilities, I have Disk Utility, Terminal, Network, Restore from Time Machine. I do not have a time machine backup so that does not work either.
    Looking at the Installer Log errors, I find the following lines:

  • HT204347 Unable to Re-install mountain Lion after erasing with disk utility! help

    I bought my new Macbook pro retina disply 13 inch last friday. played with it some time and try to restore using a time machine back up of my old Mac Air. It worked well but I didn't like it so I restarted and pressed Command + R to bring the restore utility and from there I used the Disk utility to erase my Disk and then after connecting to net I clicked reinstall Lion. First my machine was verified by Apple, then I entered my apple ID, then the mountain lion licence agreement came and i clicked agree and it started installing. Immediatley below the installation bar it showed 50 hrs remaining to finish installation. it was odd because I used to finish it within 2 hrs. Moreover the time appeared to increase from 50 to 51 and more. I waited all day without any use. it looked as if the disk has some write protection, the software is trying to install but unable to write.
    What can i do now? I am now without a  OS in my mac.

    A new Mac comes with 90 days of free tech support from AppleCare from the date of purchase.
    AppleCare: 1-800-275-2273.
    Have the serial number of the computer ready in hand and give AppleCare a call.

  • Unable to install Mountain Lion after restart

    I am uprading to 10.8.2 from 10.7.5. After the installer asks to restart the computer, it restarts; but then nothing happens. What should I do?
    Thank you.

    It worked, I should have mounted the installation image on an external drive, not the drive of my machine operating system.

  • I have a 2008 Mac Book Pro with 2gb of memory and it wont let me install mountain lion or mavericks...why not?

    I cannot get Lion to install on my 2008 Mac Book pro.  It has 2GB 667 MHz DDR2 SDRAM of memory and has a  2.33 GHz Intel Core 2 Duo Processor.  Is there still something that I am missing?

    OS X 10.9.4 is the current release of the operating system. Older versions are not available from the app store. Does your system meet the requirements for OS X 10.9?

  • Is it possible to downgrade to mountain lion with the help of a time machine backup after having updated to Mavericks?

    Is it possible to downgrade to mountain lion with the help of a time machine backup after having updated to Mavericks?

    Just to be clear, if by downgrade you mean uninstall, then the answer is technically, no.
    You can't uninstall an OS. You can erase and re-install the old OS, but if you don't have a prior backup of your data, you'll lose it during the erase procedure.

  • MacBook pro 2009 is slow and freezing after installing mountain lion. Cannot get iPhoto to open fully, other apps are freezing.

    Help! I thought I was doing the right thing by installing Mountain Lion on my 2009 MacBook Pro. It took forever to download correctly and now it is performing so poorly (freezing during applications, have to use force quit, have to use power button to shut it down, etc.) that I wish I never installed it! I want my old operating system back!

    Boot in safe mode.* This will cause certain caches maintained by the system to be rebuilt. The instructions provided by Apple are as follows:
    Be sure your Mac is shut down.
    Press the power button.
    Immediately after you hear the startup tone, hold the Shift key. The Shift key should be held as soon as possible after the startup tone, but not before the tone.
    Release the Shift key when you see the gray Apple icon and the progress indicator (looks like a spinning gear).
    *Note: If FileVault is enabled under OS X 10.7 or later, or if a firmware password is set, you can’t boot in safe mode.
    Safe mode is much slower to boot than normal.
    When the login screen appears, reboot as usual (not in safe mode) and test. There's no need to log in while in safe mode.

  • Calendar alerts on every device after installing Mountain Lion. How do I stop this? Tech support acted like I was the first person this happened to. Anyone have the solution?

    I have Calendar alerts on every device [Mac/iPad/iPhone] after installing Mountain Lion. How do I stop this? Tech support acted like I was the first person this happened to. Anyone have the solution?

    Well, whichever device you uncheck = exclude from calendars (and reminders) via iCloud will be excluded as both, receiver and sender. It's an "all or nothing", I guess. Otherwise it'd get more complicated, and the support calls could easily fill an extra forum...
    @lmp68: don't think iTunes is it, in the days of iCloud that would sure take quite an extra effort, if possible at all.
