Trying to install Mountain Lion over Lion. Only have the one partition on my drive, no Bootcamp, no filevault, no time machine, drive is Mac OS Journaled. Eveything is kosher, seemingly, according to Apple's instructions.



Cannot create recovery. And I can't even continue. What's going on?


Tried installing from the DMG, didn't work. Burned to a DVD, doesn't work. It doesn't seem like this should be this difficult. And I can't find a solution that looks like it'll fit this.

iMac, Mac OS X (10.7.4)

    Launch the 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. Click Utilities, then Terminal in the icon grid.


    Triple-click the line below to select it, then drag or copy the text — do not type it — into the Terminal window and press return:


    diskutil list


    Post any lines of output that appear below what you entered — the text, please, not a screenshot.

    That did it! Thanks for linking that. Not something I would've found easily. I tried doing something around 128mb, but it said it was too small to do, so I knocked off a gig or two and that was fine. I don't use the internal drive for a ton so I'm not going to miss a small percentage.

    As mentioned in the article, you can revert the partition to its original size after the installation.

    hmm. Unable to do so. Not allowing me to drag further than current amount, and entering in manually does not hold.


    Not a big deal though. I'm not at 50% capactiy even and don't see it happening any time soon.
