  • Reverting back to Mountain Lion from Mavericks via Time Machine?

    Hi all
    I'm wondering if anybody has successfully downgraded from Mavericks back to Mountain Lion. I am fed up with all the bugs with Mavericks...I should never have upgraded. However, I did make a system backup via Time Machine before upgrading. I'm not sure if it is possible to go back, though. Has anyone successfully done it via Time Machine? I'm also having trouble getting to the restore menu - I have a PC keyboard (which works fine for the Mac), but it doesn't do anything when I hit Command (well, the PC equivalent) + R or Option when I restart. The only thing that seems to work is Command+Option+R, which takes me to the Internet recovery, though I'm not sure if I can go back to my old system via Time Machine on that. Anyway, would appreciate any thoughts on this.

    Boot OS X Recovery by holding ⌘ r (two fingers) while you start your Mac. OS X Internet Recovery, which you were able to invoke with your non-Apple keyboard, will work just as well.
    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. After that, uninstall any third party software and system modifications incompatible with Mavericks before contemplating an upgrade.

  • Reverting back to Mountain Lion from Mavericks

    Hi,
    I just upgraded up OS X Mavericks and all of my Adobe software (Photoshop, After Effects and Premiere) open and work fine.
    When I open Encore CS 5.1, it freezes with the Beach Ball. Is there anything I can do or download to get it to open up?
    If I have to, is there a way to go back to Mountain Lion without erasing my hard drive and losing all of my software. I use Encore and it worked fine in Mountain Lion. 
    Thanks in advance.

    You'll need to purchase a USB HD and backup first.
    Then see: https://discussions.apple.com/docs/DOC-6162

  • Reverting back to mountain lion from maverick

    My system has been very slow and unstable after upgrading to Maverick I would like to do a clean install of Mountain Lion. What I need to know is can I copy all my applications on my current system drive to an unused internal drive and reinstall them back to the system drive once Mountain Lion is installed or is there a better way to go about this?

    why not leave well enough as is.  Then install Mavericks on a new SSD instead. Hope you planned ahead and made your own flash installer and saved the package from before so you don't need to redownload.
    As for your experience, may you upgraded over ML? Maybe you have things you didn't realize but that are not compatible or never should have been there. Or something.
    I would never upgrade in place.
    Setup Assistant will offer to import from any system it sees when it loads the first time, so you don't need to do anything in that regard. Other than make sure you have latest drivers, apps, programs and such - but I would take it slowly and see how a clean install of Mavericks runs first.
    And CLONE your system(s) before upgrading, or installing, or making changes. It really works and lets you boot off any system you want, on any drive - SSD, one drive wtih ML and Mavericks on it.
    The SSD will make the best improvement in performance. 250GB is now $154 for Samsung's 840 EVO.

  • Why doesn't Migration Assistant recognize my backup disk after rolling back to Mountain Lion from Mavericks?

    I rolled back my OS from Mavericks to Mountain Lion and now the Migration Assistant isn't finding my Time Machine backups.  Any idea why this is?

    One reason may be a different computer name.  Check System Preferences > Sharing and make sure your computer name has been the same through all your various OS X iterations.

  • Clear procedure to move back to Mountain Lion from Maverick

    Hi,
    I had a question related to the purchasing of Moutain Lion on apple store.
    Having some trouble with many of my device (for egs 3G key) which are not upgraded (software) to face Maverick, I bought online a version of Moutain Lion to downgrade to this OS for the time needed to see the drivers being uprgraded
    But it seems the procedure is quite complex when you have to face a downgrade of the OS.
    Is there any clear procedure available to follow to realize such change (answers on forums are numerous but often complex)
    Thanks in advance for any response

  • Going back too Mountain Lion from Yosemite on new Mac Book Pro

    Okay so I just got my first Macbook Pro I am Very happy with it I don't have any real problems with Yosemite HOWEVER I bought my mac as I am a music student and I work with macs all the time running Pro Tools so it made sense to get a mac for compatibility reasons. now, I am not able to install Pro Tools Express the program I use at home online there are claims that it is the installer that is broken and won't work unless you are running 10.9 or lower but the program runs fine. I have bought Mountain Lion and I am awaiting it to be emailed to me, and I am away to create a partition on my 8gb usb stick to put the installer on, I understand that apparently I can't downgrade as I have a new Mac but I can run them together? Well one at a time obviously, I just would like some help as I am a little confused having only ever used Windows before.
    Thank you for any help! I'm just getting pretty frustrated with this whole ordeal.

  • How does one revert to Mountain Lion from Mavericks?

    I got a new iMac a week and a half ago. It was running Mtn Lion, with i73.5, 8gb ram. I upped the memory to 16gb and installed Mavericks.
    Now I have some issues that others are experiencing with Photoshop: some keyboard shortcuts not working, strange cursor behavior. There are some other things, just within my computer's behavior, that I'm not sure aren't related to Mavericks, as well, but since I've never worked on a Mac before last week, I just don't know.
    The problems seem to be fixed, as reported by others over in Adobe forums, by reverting to Mountain Lion, and waiting for bug fixes in Mavericks.
    I am new to the Mac world so I'd appreciate some detailed advice on the best way to do that.
    Thanks for your help.

    You should be calling AppleCare regarding problems with a new Mac. Telephone support is free for the first 90 days of ownership.
    Various Adobe apps have had problems with Mavericks. Apple can't fix Adobe's problems. Consult Adobe for support options.

  • I have switched back to Mountain Lion from Mavericks. Now I can't add iPhoto back to my computer. To save headaches I even tried to purchase again but in the app store, the old version is not available..?

    Please help.

    You will have to
    reinstall from the original source
    Could be
    1 - the restore disks that came with the computer
    or
    2 - the iLife DVD that you purchased
    or
    3 - the app store - log in under the Apple id used to purchase the software or to set up the computer - look under purchases - you might have to unhide or accept the Application first
    Then you will have to restore your backup of the older iPhoto library from your backup

  • How to go back to Mountain lion os x 10.8 again from mavericks.?

    How to go back to Mountain lion os x 10.8 again from mavericks.?

    You can reinstall your system from a backup (Time Machine or "clone") or erase it completely and reinstall Mountain Lion.
    OS X Mountain Lion: Erase and reinstall OS X
    If your Mac shipped with Mountain Lion already installed, you can reinstall it. Otherwise, you can only reinstall Mountain Lion if you purchased it from the App Store.
    You may be better off describing the problems you're experiencing, so that they can be fixed. The vast majority of Mavericks complaints are due to outdated or poorly written software or similarly incompatible system modifications, and some simple troubleshooting may reveal the cause.

  • How to keep finder in mountain lion from opening at startup

    How to keep finder in mountain lion from opening at startup.?

    Now you got me thinking....
    One can set things up so Finder can be quit like any other application.  In Terminal:
    defaults write com.apple.finder QuitMenuItem 1
    Then relaunch the Finder.
    I guess it might be possible to make a an Applescript or Automator application which runs at start up and quits the Finder.

  • I just upgraded my system to Mountain Lion. If I restore my Macbook Pro back to the very beginning state, will the Mountain Lion be removed or not? Thank you

    The only problem that I forsee is that some have reported problems getting machine-specific builds of Lion via Internet Recovery. Not sure if it's working yet or not. But you could give it a shot, I suppose. Basically what you want to do is 'prepare your computer for resale' - just like it came out of the box. Kappy, a pretty wonderful and very knowledgeable man, has tip for that which I have copied and will paste below:
    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.) 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 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.
    Good luck,
    Clinton
