How to install final Lion over dev Lion?

I installed a developer version of Lion. Now I want to buy the final version in the App Store. But Lion is reported to be 'installed'. So how do I do a force install, short of starting over and installing Snow Leopard first?

Which dev Lion version do you have. I haven't yet heard a definitive statement on the issue. The previous definitive statement doesn't seem very definitive anymore. I would sit tight for now.

Please stop asking about that on this forum.
There are plenty of informations on the Internet if you want to do it but nobody here will help, because is against the forum's rules.
And, you can't buy Mountain Lion if you do not have a Macintosh with at least Snow Leopard installed.
There is no physical media. Mountain Lion is provided by Apple through the Mac App Store.

How to install mountain lion with a different apple ID?

More information would be helpful. If you are going to use a different Apple ID, you will need to buy Mountain Lion again. If you have a computer that has Mountain Lion installed, but Mountain Lion was purchased with a different Apple ID you must use the original Apple ID to download Mountain Lion.

How to install Aperture 2 over Academic 5.1

I have academic Aperture 1.5.6 installed on my 17" PB. I have purchased the full Aperture 2 since there is no academic upgrade. How do install Aperture 2 over Aperture 1.5.6. (There are no instructions in the material that came with Aperture 2.)
Thank you,
Susan

Aperture is pretty much self contained. Just install it (or, if you prefer, delete Aperture 1.5 from your /Applications folder and then install Aperture 2).

How I installed Mountain Lion on Un-repairable Hard Disk.

My Recommendations for Avoiding Trouble, Avoiding Risk, and Saving Time.
1) Make a boot clone first!!!
      http://www.bombich.com/
http://www.shirt-pocket.com/SuperDuper/SuperDuperDescription.html
2) Fix and repair your hard disk with Disk Utility and fsck_hfs before installing Mountain Lion!
    (Otherwise the installer will write-lock the disk preventing repair.)
Mountain Lion Aborted Installation—Claimed Hard Disk Failed, Couldn't be Repaired, and Should be Replaced
I have a 2011 MacBook Pro. Installation of Mountain Lion aborted claiming the hard disk could not be repaired by Disk Utility, should be backed up immediately, and replaced. It didn't make sense that the drive was booting up the computer for installation, but needed replacing. I removed the drive, put it in an external enclosure, and backed up the drive using a working Mac Mini, and Carbon Copy Cloner.
Hard Disk Was Write-Locked—Not Failing
Booting in Single User mode (hold command and S keys down while bootup is proceeding). I then typed in the fsck command given after Single User bootup. It informed me the drive was write-locked and read only. Now things were starting to make sense. Disk Utility couldn't repair the drive because it was write-locked! Maybe it could have been unlocked by the "chflags nouchg /Volumes/volume" or "chflags noschg /Volumes/volume" commands (http://hints.macworld.com/article.php?story=20031017061722471), but I didn't try it. Unlocking the drive is really worht a try because it could save hours of coppying through a slow USB interface.
I formatted my laptop drive after copying it to another large external drive. Then I used Carbon Copy Cloner to clone Snow Leopard from my Mac Mini to my freshly formatted original laptop drive. I unsellected the "Users" folder so I would only get the operating system—saving lots of hours copying data I don't need. Then I put the drive back in my laptop, and it booted with Snow Leopard. Checked the volume with Disk Utility and was informed the drive is fine. I removed the drive and connected it externally to my Mac Mini and ran fsck_hsf a few times in the terminal, which showed problems were found and fixed.

I put the drive back in the laptop and repeated the fsck commands after a Single User boot. (Omited the sudo commands and used /dev/disk0s2.)
Downloaded and Successfully Installed Mountain Lion on "Unreparable" Drive
I downloaded the Mountan Lion installation application to my laptop, ran it, and had a smooth install.
More Trouble Migraiting My Applications and Directory
I expect to use up more time changing my computer name, migrating applications and rsyncing my User Directory. I will post how I achieve this.
I Hope People Avoid Trouble and Problems are Solved
I hope everyone will avoid trouble by making boot clone of their whole disk before attempting an install of ML and repairing their disk with Disk Utility and fsck before ML installer prevents it with a write-lock. Please see the first section.
I hope this solves other peoples problems with 'unreparable' disks. I believe this proves disks are repairable when ML says otherwise.
Good luck everyone!

troca, you certainly helped dtigerbme! Isn't that encouraging?
I recommend you copy your drive as soon as possible. I really don't think the drive is bad, but you may have to format it and copy back to it. Hopefully not. Clone or backup the drive before trying this recipe. Any time you have errors on a drive, back it up. A failing drive has lmited life. However, I don't think these drives are really failing, but that is my opinion and I break a lot of things.
Let's try this recepie for you:
Start in Single User Mode. Power on while holding the Command + S keys.
At the prompt, type "fsck_hfs -fy" or "fsck -fy" and hit return.
Do it again.
Enter the command "reboot".
Just googled "volume count disk utility" and got the same recipe to fix it.
http://counterjumper.com/post/19265700171/how-to-fix-invalid-volume-free-block-c ount-error-in
So my recipe is to try to fix the drive without taking it out of the computer, which requires you can boot it up.
troca it looks like Apple has said that error is benign and can be ignored in 2010.
http://support.apple.com/kb/TS2028?viewlocale=en_US&locale=en_U
I do believe fsck will fix it though.

How to install Mountain Lion on New Macbook Pro from APPS

How can I install Mountain Lion into a VM on a New Macbook Pro running YOSEMITE from APPS
I have it in my apps purchased but It tells me the system is to New to download/run it
I have tried mounting my install ESD copy but it has the same Problem
I don't have another Mac
Thanks

I think the problem is that you can't install an older OS X version onto a system running a newer OS X version. So I would try the following:
     1. have an external disk or create another partition on an internal drive to use for the Mountain Lion install (you might have to shrink an existing partition to make room for another)
     2. Create an external bootable USB thumb drive with the Mountain Lion OS on it (do a search on the web for this - for example see http://www.macworld.com/article/1167857/how_to_make_a_bootable_mountain_lion_ins tall_drive.html
     3. Reboot Yosemite and then boot from the USB thumb drive by holding down the option key
     4. run the mountain lion installer and install on the new disk/partition you created in step 1 - it will also create another recovery partition from this same part of the disk
Now your Mac system will have both a Mountain Lion install as well as the Yosemite install. You won't be able to use Migration Assistant to move things from Yosemite to Mountain Lion because it will see that you're "going backwards" and won't allow you to.
Have a good backup of everything before starting in case there are problems.
Good luck...

How to install Mountain Lion on my macbook pro MB990LL/A 2009?

Hi,
I have a big problem here.. I saw on internet that many people have installed on they're macbook pro MB990LL/A an OS like Snow Leopard, Lion, Mountain Lion. This weekend, I've tried to install Snow Leopard, and when I've inserted the disc in my macbook, it said that the operating system was not supported by my computer.
I don't kow how to do, but I would like to install Mountain Lion or at least Snow leopard on it and I know that it's possible so if someone can help me with this, that would be great!!
Right now, i'm on leopard 10.5.8

Confirm that you booted from the Snow Leopard Install DVD and that it is the retail version that you purchased directly from Apple.
If that does not work:
Boot your MacBook Pro normally, then download and install the Mac OS X 10.5.8 Combo update. Then, shut down and attempt to install Snow Leopard again.

How to Install Mountain Lion on a mac Without any software

My issue is that I have a MacBook air. I lost everything that came with it. I don't have the CD for the software. Not knowing I needed the CD to install the software (because on my imac i never needed to), I restored my macbook to factory settings. When I tried to turn it on again, it said I needed to install mountain lion. I tried but it said I haven't bought the mountain lion with that apple id. So I did exactly that. I bought the mountain lion software with that apple id. The payment was confirmed and I received an e-mail with the info and the access key or something. I went to the website and it says my order is complete. Except that when I come back to my computer and type that same apple I.D. It says mountain lion wasn't bought with that I.d. But I had just done that.
So what could to install mountain lion on a computer that currently doesn't have any softwares intalled? Why is it saying I didn't buy it when I just did and the status here says it's complete?

The redemption code you received is used to download Mountain Lion the from the App Store.
Open the App Store. Select either Featured, Top Charts, or Categories at the top of that window then click Redeem under Quick Links on the right.
Reinstalling to factory settings does install OS X.

How to install Mountain Lion on blank hard drive

I bought a used macbook with the understanding that the hard drive crashed and I had to completely replace it. I've bought and installed a new, blank hard drive in the macbook and I was wondering if I could purchase mountain lion from the apple store and install it on a completely blank hard drive. When I first booted it up, it takes to to a screen that asks me for my wifi password and has an icon for internet recovery. I've clicked on it and after a while it shows me a globe with a question mark and the website for apple support. Please tell me I haven't already messed it up :S

You need to install Snow Leopard or Lion first to install Mountain Lion online via Mac App Store.

How to install Mountain Lion

Hello, I need to install Mountain Lion (10.8.5) on a Mac Mini running Maveicks. I have the installer, but it won't open. Can i have some help?
Thanks

See this related post by keg55. Sounds like this guy has done this more recently than I.
keg55 indicates holding Command-option-R during startup...
https://discussions.apple.com/message/24244443#24244443
Another thing you could try is reboot and just hold down the option key
(or maybe command key).
You will get a choice of which operating system to boot into.
One will be labeled Recovery, selecting that should start the same recovery process..
I haven't done this for a while.. and I always configure my option key to be my command key, so that adds to my confusion... (For me holding down the option key during startup provides the list of install operating systems to boot into, for you it might be the command key.. but I'm pretty sure it is the option key..)

TS2521 how to install final procut 7 in iMac

I want to install final procut7 to my iMAC, but they not go though. The massge show on is "powerpc applicstions no longer support"

Final Cut 7 will run on your iMac under Mountain Lion. Take another look and see if the version is 6 or below... FCP 6 or 5.1 will run on your iMac but the installer is an powerPC app and will not run under Mountain Lion. Ask in the Final Cut Studio forum on how to install FCP 6/5.1 on your iMac.

FCP 5.0 and below are powerPC apps and will not run in ML.
