How can I uninstall Mavericks? I use software daily that is not currently supported with Mavericks and is required to complete my job. I can not wait for the develoiper to release a patch (they said it would be awhile).

 

I need to revert to mountain lion. I tried CMD R when booting but it only gives me the option to reinstall Mavericks. I only have access to a windows machine now. How can I revert back to Mountain Lion? Is there a link to a image for mountain lion somewhere on Apples website that I can not find? Is there a trick in Recovery Mode to choose mountain lion instead of Mavericks?


MacBook Air (13-inch Mid 2013), OS X Mavericks (10.9), Uninstall Mavericks

    Boot into Internet recovery mode, +OPTION+R, and you can restore the OS that shipped with the machine. Alternatively, restore the bootable backup/clone or TM backup of your previous MLion installation.

    Thank you so much, this resolved my issues.

    Which one? Using Internet recovery or restoring a backup?

  • penutz Level 1 Level 1 (0 points)

    Internet Recovery. Thank you.

    I tried internet recovery but it told me I couldn't install Mountain Lion because I had a new version of OS X.  Did you not get that message?

    I backed up all of my data while in mavericks and then deleted the partition with Mavericks OS on it. So essentially it was a brand new drive. Then cmd option r on reboot!

    thanks so much penutz.  I'm not sure about this.  I did do a back up yesterday to an external drive after I upgraded to Mavericks.  I can do another one today.  So now Mavericks is on the Hard Drive in my Mac.  Can you help?  Do I erase that drive then?  Is there a way to just see the partition and delete it.  I'm pretty new to Macs.  I think when you say it was essentially a brand new drive, you are saying you erased the HD?  When I go into Disk Utilities, I do have a BASE SYSTEM that has Mountain Lion on it, and then there is the Mac HDD.

     

    I hope I'm making sense.  When you say you deleted the partition with Mavericks OS on it, what exactly did you do?  Thanks again.

    Baltwo:  when I try to restore to Mountain Lion using internet recovery, I get an error message that says I can't because I have a newer version (i.e. Mavericks).

  • baltwo Level 9 Level 9 (61,830 points)

    As penutz noted, you should backup your data, boot into recovery mode, use Disk Utility to erase the HD, and then boot into Internet recovery.

    I think I'm getting it.  Have erased the partition but lost some of my apps so am working on getting them back.  As you said can't migrate data but have been able to restore most files from my back up.  Thanks for all the help.

    Hello,

    I recently ordered my first Mac, a 15inch rMBP, however I was disappointed to find out several CAD applications I use regularly are not supported.

     

    My MBP will ship with Mavericks already installed, is there a straightforward way for me to downgrade to Mountain Lion right from the start?

    I will upgrade in a few months once third party devs catch up, so I wouldnt mind rebooting to a Mavericks default by that point.. I don't want to lose the free iWork/iLife etc.

     

     

    If someone could shed a little light onto the matter I would appreciate it, I wanted to avoid making a new topic since this thread was relevant.
