HT4649 applies to Lion. I am on Lion and want to upgrade to Mountain Lion. Does this mean I have to wipe my disk (an SSD) and reinstall Lion to install Mountain Lion or must I really attempt to go back to Snow Leopard then to Mountain Lion. I am fully prevented from installing Mountain Lion, probably because I have a third party SSD. Any suggestions?

Mac OS X (10.7.3), 15" 2.6 GHz

    You should be able to install ML right over Lion. You will of course be backed up.

    You do not have to erase your drive nor revert to Snow Leopard. Mountain Lion will upgrade your existing installation of Lion, preserving your applications and user data. I strongly recommend a good backup, preferably a clone of your entire hard drive, prior to installing Mountain Lion, as a precaution in case something goes wrong.


    I also recommend making a copy of the Mountain Lion installer after it downloads but before you run it, since it's erased after running and having a copy makes future reinstallations easier (it's still possible even without it, it's just easier if you have a copy).

    Varjak -


    You touched on a point I've been searching for.  I am about to upgrade to ML.  I use TM to back up to an external hard drive.  How do you make a copy of the ML installer?  I've always gone to store and bought OS disks, but will try the download route for the 1st time.  I have both writable CDs and a thumb drive with about 3.7 Gb on it. 


    Also, any suggestions to avoid the problems some others seem to be having with the ML upgrade and backing up via TM?

    Wow - lots of info.  Thanks to you both.  I will buy either writable DVDs or a bigger USB drive tomorrow before I try all this. I will post my results, with thanks!  Another question this poses, is - since I've always used CDs for backups and/or my external drive - it seems that people are recommending DVD s to back up.  Obviously, they hold more data, but I've never really used them - do they work the same way for backing up data, etc? Just more space? I always thought they were just for movies.


    Anyway, to the point of the original post, I will follow up as I do this over the weekend, and - again - my thanks to you both!

    Okay, I've tried to follow these instructions (to burn to DVD, since I had plenty and no thumb drives big enough - anyway, we keep losing those little suckers) and it didn't work. I downloaded ML and did not install, as suggested. But first, when I fired up "Disk Utility" it prompted me to "Burn ML to DVD."  I figured maybe this had gotten more intuitive, so I tried it.  Took a while, and it DID burn to DVD, but when I tried to install FROM the DVD, I kept getting error messages.  So then I followed the instructions to find the "InstallESD.dmg" file, but when I fired up the disk utility, none of the prompts showed up - no "partition" tabs, etc.  Maybe that's from an earlier or later (my machine is a 2008) system that I don't have, though I did update to Snow Leopard and am running the most recent update.


    So I give up.  I'm just going to install ML without backing up.  I've never had a problem in the past which required re-installing, and if I do, I'll just take it to the Apple store near me.  Too frustrating to keep trying to do something I'll probably never need.  


    Thanks for your help -  Wish me luck!

    Same problem manoaHI,


    The Apple article we're commenting on treats that recovery as an option you can skip, however the actual install gives you no option and fails if it cannot create the recovery. My support thread was titled "Contradicting Instuction", its a shame Apple hasn't responded to this major issue.


    That being said, looks like the only way will be by backing up, booting from disc or USB drive bootup, running Disk Utility and reformatting / repartitioning our drives to match the new Mountain Lion way... what a way to kill any enthusiasm I had for this release. I bought the upgrade the week it came out and have not yet installed it due to this painful process.


    Cheers and good luck..
