    Mountain Lion Won't Install On 2010 MacBook Pro
    After I downloaded the Mountain Lion; it won't install because it says my hard drive is on a back up drive for the time machine. I've never used Time Machine and I only have one hard drive, Any suggestions on how to resolve this?

    As per this article:
    Bugs & Fixes: Troubleshooting Installing Mac OS X Lion | Macworld

    This message again means that the Lion installation will not successfully complete. The message can appear even though your startup drive is obviously not acting as a Time Machine backup. As covered in an Apple Support Communities thread, the likely cause is an errant Time Machine-related Backups.backupdb folder at the root level of your drive. This folder, created by and used by Time Machine, is fooling the Install app into thinking your startup drive is actually a Time Machine backup. The solution is to delete the folder.

    Please verify and include the exact model/year of your Mac and OS X version number (available from "About This Mac", then "More Info" on the Apple menu).

    Thank you but I am having a problem locating this folder to delete. Where do I locate it?

    It'd be at the root level of your hard drive. In the top folder where you'll see folders named System, Library, Users, and Applications. In the Finder, just click on your hard drive's icon in the sidebar to get there.

    Of course, this is all assuming that the folder is there and thus the cause of your problem.

    Please verify and include the exact model/year of your Mac and OS X version number (available from "About This Mac", then "More Info" on the Apple menu).

    It would be rather pointless to use it on the internal drive, now wouldn't it?

    Sure it would . . . I was just hinting that everyone should back up their stuff. OK...I'll butt out.

    He pointed to that article because the problem and fix are the same. He knows what he's doing....

    Do not cross post! You've now posted this same subject three times in two forums. Only post one time and continue with the same thread until it's resolved. Your cross posts have been removed.

    So Chuckles, you "think" he told me…??? Get back to me when you are more certain. LOL! And while yer at it, since you are such a whiz, we're all ears for advice of your own for the OP's problem. Mine wasn't godsend nor was it ever portrayed as such, but was the best and most likely culprit at the time.

    Specs:
    Mid-2012 MBP (16GB, 1TB HD), Monoprice 24-inch second monitor, iPhone 5s 32GB, iPad Air 2 64GB
    Having successfully (and remarkably easily!) installed Mountain Lion on a 2009 MacBook Pro, I know for a fact that it can run on a 2010 MacBook Pro.

    Time Machine will back up changes to the machine's own internal HD if it is TURNED ON and there is no external HD present. So my guess would be that TM is turned on. Turning it off may be all that is necessary to make the upgrade work.

    Same Problem Here..
    Hey,

    I think I have the same issue.
    The only difference is that I downloaded Mountain Lion as a torrent (from a trusted source)
    Mountain Lion won't install, I turned off the Time Machine thingy, but that didn't help.

    We're not going to help you install a pirated copy of anything.
    If you want Mountain Lion - spend the $20.
    This thread is now closed.
    I cannot be held responsible for the things that come out of my mouth.
    In the Windows world, most everything folks don't understand is called a virus.
