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..)

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 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 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 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 with app store/or bootable drive?

My hard drive recently failed and I had to replace it. How would I got about getting mountain lion installed without the app store. I have a time machine backup but that would only be able to restore my syatem not install the OS. Any ideas on how I can get mountain lion. I only have access to PC so I can't create my own bootable drive.

My fathers iMac unfortuneately doesn't run snow leopard..
Beware : Because the Machine now is a Leopard ( 10.5.x ) one, check the following :
If the iMac is a PowerPC one ( G4/G5 processor ) , then it can't run either Snow nor Lion, because both require an Intel processor. If that is the case, then OSX 10.5.8 is the last available and maximum OS it can run.
Snow Leopard runs on any Intel if at least 1GB Ram is present, while Lion needs a 64bit Dual Core Intel CPU ( Core2Duo or later ) and double the amount of Ram , 2GB minimum.

How to install mountain lion for free because of new mac

I choosed mountain lion in app store and got 19.99$ decrease of my account. My mac is among the latest group and promised of free updating. What should I do?

Hey, I was in the same boat as you,
go here https://uptodate.apple.com/UtdPrepareAction?program=Mountain%20Lion&locale=en_us

Surley, there must be a way to change/alter/modify my powerbook G4 to install Mountain Lion.

Any Ideas on how to install Mountain Lion on a 2007 PowerBook G4? What modifications if any can be made? This is such a fine machine I hate to get rid of it. PS I am not a geek but I am willing to try something.
My wife has a new Mac Book Pro and I don't like it.

The PowerBook G4 is a fine machine. One of Apple's best. I know because I loved mine very much.
But that means I also know how it feels to move up to an Intel Mac. And the fact is, any Intel Mac is much faster than a PowerBook G4 which is a decade old now. As much as I loved my PowerBook G4, once I used an Intel Mac, the G4 felt slow and awful. Even if you could install Mountain Lion, it relies so much on the power of current technologies, processors, and graphics that it would probably be a horrible experience on a G4 because the G4 would not have the power to run ML at the speed for which it was designed.
Why is it that you don't like the MacBook Pro? Is it the screen? When I moved from the PowerBook G4 to the MacBook Pro I ordered the anti-glare matte high-resolution screen. This gives me a matte screen with a metal bezel, which I greatly prefer to the glossy screen on shiny black bezel of the standard MacBook Pro. In all other respects (except the black keyboard keys) this MacBook Pro looks and feels like my PowerBook G4, only many times faster.

How do I Install Mountain Lion on a Mac with 2 Drives

Good day ALL,
I am upgrading my Mac mini to add a second hard drive (solid state). After the HD install is complete I plan to re-install Mountain Lion and transfer my Applications, Files, etc from my backup. I am very comfortable with installing Mountian Lion on the solid state drive and making it the bootbale drive, my questions are:
1. It is a 120G soloid state hard drive, so I only plan to use it for the OSX system, Library and Applications. Should I include other files?
2. I plan to use my 750G SATA drive for the Users. How do I set up the User Folder archive on this drive? Do I just move it?
3. Then how do I ensure the User Folder on my backup, gets retored on the right drive?
Thanks

Regarding 1:
$ cd /Users. sudo ditto myname /Volumes/TimeMachine/myname copies everything in $HOME to non-TM backup.
Ensured latest SSD firmware up to date.
Clean install of ML to SSD from 8GB USB stick created by Lion Diskmaker.
$ cd /Users. sudo ditto /Volumes/TimeMachine/myname myname (see part 2 for /Users on another drive)
Added latest Xcode and command-line tools. Added VirtualBox 4.1.20. Put the 65GB VirtualBoxVMs folder on the second drive. Edited the ~/Library/Virtualbox/VirtualBox.xml file for the new mount points. Beware that many SSD (including Vertex) warn not to exceed 50% drive capacity or they will invoke slower drive controller algorithm. After some clean-up and re-arrangement, I have 98GB free on this SSD. It sings.
Files that are heavily accessed/shared by users would be consideration for the SSD
Regarding 2:
If you have sufficient external storage, back-up your pre-ML /Users either with ditto as I did, or with TM, somewhere other than the 750GB drive.
Use DiskUtility and repartition the 750 as one (or more) GUID HFS+Journaled partitions depending on planned usage.
Reverse the back-up to put your user(s) on the 750GB drive
In System Preferences > Users & Groups, unlock, then right mouse button click on individual user names. Advanced options ... will appear. For Home directory, Choose ... the particular mount point for individual user accounts now on the 750GB drive. Done.
Regarding 3:
Because you have moved individual user accounts from the internal drive where your last TM backup occurred before ML installation, TimeMachine will not understand (as far as I know), the new /Volumes/750GB/User/you home directory location that you just changed in #2. Another reason I used ditto(1).
If you do not want Spotlight to index that 750GB drive, you need to inform Spotlight Preferences > Privacy to exclude the drive.
Hope this helps.
PS: Darn advanced editor eating bullet formatting!!

I installed Mountain Lion so that I could sync my notes with my iPhone that already syncs notes with a specific email address I use for school, but during the install it automatically set up Notes to sync w the wrong email addy. How can I fix it?

I installed Mountain Lion so that I could sync my notes with my iPhone that already syncs notes with a specific email address I use for school, but during the install it automatically set up Notes to sync w the wrong email addy. It looked in Mail, which had 5 email accounts set up in it, and for some reason picked the only one that I no longer use because it is for a school that I no longer attend. How can I fix it so that it syncs with the correct email account for notes and calendar? There don't seem to be any settings available other than to check if you want to use the basic features. It also said during the set up that it was setting up 'find my mac' but if I look on the iCloud website there is nothing showing there for finding my mac.
At this point I feel like I wasted my money paying for this supposed upgrade. I got nothing for it but frustration. It even automatically set my security settings to allow only downloads from the Mac store so the first time I went to download something I had to stop what I was doing and go correct settings first. I feel like there should be a security setting to block downloads from the Mac store so I don't accidentally end up clicking the wrong thing and being charged.

iCloud isn't syncing them on your phone. You simply added the email account to your phone and enabled calendar and notes syncing with the email provider, and the calendar and notes appear in the calendar and notes apps on your phone. You can do this with Gmail, Yahoo and other IMAP account. iCloud email is just another IMAP account, but syncs notes with Apple's iCloud server just as Gmail syncs notes and calendars with Google's server.
iCloud didnt' set up a non-iCloud account on your Mac. When you check Mail in System Preferences>iCloud, it only creates an iCloud email account. You can also add other email accounts to your Mac by going to System Preferences>Mail,Contacts,Calendars and clicking on the "+" sign on the bottom of the left sidebar. If you added these other email accounts to your Mac before you upgraded to Mountain Lion, these were simply maintained on your Mac after you upgraded.

How do I use Disk Utility to help install Mountain Lion after many failed attempts?

I tried to install Mountain Lion from an App onto my MacBook.
First it said that my disk was damaged to i tried to repair it.
Didn't work.
Then it said I didn't have enough room to install Mountain Lion.
Then I tried to restore Lion.
Didn't work.
Then someone suggested I reset my PRAM.
Tried that, and now I am stuck.
I can't restore any of my backups from timeline.
I can't reinstall OSX because my drive is now locked.
And I don't know how to use Disk Utility to solve this problem!
Any suggestions welcome... I'm in way deeper than I understand and feel like anything I do is making this worse!

I gather that your computer is in a less than satisfactory state, so the process below will basically start you from scratch, but you shouldn't lose anything.
Okay, can you inspect the Time Machine Backups with the Finder? About two or so folders down you should start seeing your system files. Assuming all your files are present.
Important^
You probably have an installation disk that came with your macBook. Boot from that CD and install from the CD.
Run the verify disk utilites and repair utilities if necessary.
You may want to erase your disk from the CD's disk utility. This will erase your Hard Drive (make sure you do not erase your backups, as that would be very bad).
Once the installation is complete, run all system updates. Either look through your backup and find the Mountain lion installation app, or download it from the app store again.
Run the ML installtion app.
Once everything is up and running, move all files and folders you want from your TM backups and you should be good to go.

Numbers does not open with the main user after installing mountain lion. It works flawlessly when I use the second account on my mac. What got corrupted in the admin-account, something in the user-library? How can I fix it? I´m kinda desperate...

Numbers does not open with the main user after installing mountain lion. It works flawlessly when I use the second account on my mac. What got corrupted in the admin-account, something in the user-library? How can I fix it? I´m kinda desperate... (the same happens with the other iWork-Apps!)
Looking forward to hearing from somebody with a littlemore expertise than me, Chris

you can remove preferences files by navigating to the Preferences folder for your user as follows:
0) Quit ALL iWork apps (Keynote, Pages and Numbers)
1) from the Finder select the menu item "Go > Go To Folder…". This will bring up a dialog:
2) enter the path "~/Library/Preferences" (no double quotes)
3) find the files:
com.apple.iWork.Keynote.plist
com.apple.iWork.Numbers.plist
com.apple.iWork.Pages.plist
and move these to the trash. I would NOT empty until later.
4) restart Numbers
