NEED HELP!!! want to install mountain lion over lion

getting message saying "this disk doesnt use the GUID partition table scheme" and when I try to change it in disk utility, all the options are grey. How do I go about upgrading to mountain lion at this point?

You probably can install it thru a DVD. Do to it, start your Mountain Lion installer. You should see it on your Dock. Just make a Right Click, select Option and Show in Finder. After it, make another Right Click on the Package and select "Show Package". Brower to Content/SharedSupport. You should see the file "InstallESD.dmg" make a right click on this file and select Open with "DiskUtility". Inside this tool, you'll be able to burn it. You'll need to use a Double Layer DVD or a Blu-Ray disk. The size of the Package doesn't fit on a regular DVD.
I did that, and now, I can have a Virtual Machine inside Vmware Fusion of Mountain Lion. I just did my installation thru my DVD -DL and it works very well.

I want to install Mountain Lion on my 2008 iMac. My current OS is Snow Leopard 10.8.6. I've heard ML may be too much for this iMac. I would appreciate anyone's advice.

I want to install Mountain Lion on my 2008 iMac. My current OS is Snow Leopard 10.8.6 and there is 4GB RAM. I've heard ML may be too much for this iMac and may slow it down. Has anyone had any problems with this upgrade?

See > http://www.apple.com/osx/specs OS X Mountain Lion requires a Mid 2007 iMac or newer, and your iMac can run Mountain Lion without any problem. 4 GB of memory are enough for Mountain Lion, but if you are going to use heavier applications, maybe you will need more RAM
Before upgrading, you must make a Time Machine backup and/or a clone with Carbon Copy Cloner, and check that your applications are supported > http://www.roaringapps.com

Open the Mac App Store on the other Mac and in the Quick Links sign into your account. See if the Mountain Lion purchase is among hidden apps in the iCloud area of your account info.

I want to install mountain Lion on an external drive without uninstalling Maverick from my computer

When I want to get mountain Lion, apple store telles me that I have Maverick installed. How can I charge the M Lion version to install on an external drive?

You would need to download a copy from the Mac App Store or already have a copy of the installer. Then you can make a bootable USB drive using DiskMaker X (http://liondiskmaker.com). Once you created the USB disk, you can boot from that and install Mt Lion on the external drive.

Help - I just installed Mountain Lion and now my MacBook Pro crashes all the time

Hi everyone. I've recently installed Mountain Lion on my MacBook Pro and now it randomly crashes. I tried finding the pattern (maybe when I open a specific app, or go through a series of steps) but nothing, it just happens, and it feels random.
Here's the latest panic report I got:

Mid-2010 15" MacBook Pros - the bad NVIDIA GPU
If you're having frequent kernel panics with your 15" mid-2010, or intermittent screen problems, the problem is, more than likely, the faulty NVIDIA GPU found in a number of those machines.
Here's just a sample of a kernel panic log that points to the faulty NVIDIA card:
Kernel Extensions in backtrace (with dependencies):

Here's the "official" Apple take on the issue - but the very real kernel panics need not be preceded by 'Intermittent black screen or loss of video'... in fact, you might not experience any video problems at all. Although video problems can certainly be a portent of things to come…
So what can you do? Print out a copy of your kernel panic and a copy of the Knowledge Base article and take them, along with your machine, to your local Apple Store or an Apple Authorized Service Provider. They should be more than willing to install a new logic board at no cost. I have no idea why this faulty GPU is making the headline here on the MacBook Pro forum so often now - could it be because Mountain Lion is just bringing the issue to a head more readily? I don't know - I only know that we're seeing more and more of these kernel panics of late.
Good luck,

HT5293 Have a older MacBook Air want to install Mountain lion but every time I try it comes back and says you cant down load on this coumputer. Why apple support said i could after they got my Serial Number. HELP

How do I install Moutain Lion Apple support said I could after they got my serial number. but evry time i try it comes back and say's cant download on this computer.

Check that your computer is compatible with Mountain Lion/Mavericks.
To check the model number hold down the option/alt key, go to the Apple menu and select System Information.

My Macbook Pro is running Leopard 10.5.8 and I want to install Mountain Lion

What are the steps for doing this?
I bought a used Macbook Pro (late 2008-2009 silveraluminum 250 GB HD model) after recently buying a new Macbook Air that I broke. My Macbook air was a 2012 and came with Mountain Lion 10.8 preinstalled (as there are no CD slots on the Air models). I do have an external hard drive and I had been using that as my time machine backup. Consequently, my entire Macintosh HD has been cloned from my Macbook Air onto my western digital external HD. However, I cannot restore from my time machine backup (external HD because it says that I do not have the same operating system currently installed on my laptop.
What do I need to upgrade to the newest Mountain Lion operating system? Do I have to buy snow leopard and then again mountain lion? That seems pretty ridiculous. Or, is it possible to just buy the mountain lion OS from the app store or buy the installation CD?
Another question, is I do not see the App store icon on my dock when I have my desktop up. How would I buy Mtn Lion if I cannot access App store. Does Leopard not have an app store app??
Please provide links where I can find necessary software updates and steps to take to get mtn lion so that I can transfer my clone HD off my external hard drive to my laptop I just bought.

First you have to get the Model Identifier from System Profiler, then make sure of it's model and RAM amount, then use Crucial.com or OtherWorld Computing and max out it's RAM capacity.
There is a 10.5 version of MacTracker here that can assist in getting the full RAM capacity of the machine, not just the amount Apple provides, and the RAM specs.
http://mactracker.ca/archive.html
Install/upgrade RAM or storage drive in Mac's
Also a machine that daed is likely got a dying boot hard drive, so you should replace that also with something like a 7,200 RPM for better performance, large storage capacity and decent price. A SSD would be price overkill for that older machine and add another level of problems enabling TRIM support etc.
Next you need the 10.6 white retail disk Apple sells online.
Next you follow this User Tip for installing 10.6 on the new drive. It is advised to Zero Erase the entire drive regardless of new or the old one.
How to erase and install Snow Leopard 10.6
Once 10.6 is installed you use the 10.5 disks to install your free iLife, then use Software Update repeatly until clear to get to 10.6.8 which provides AppStore for 10.8 install (paid).
Now comes the problem. Later OS X verisons of 10.7+ are better on MacBook Pro's Early 2011 and later, the performance drops off if you use machines earlier than 2010 models.
It's because 10.6.8 was written to be a performance oriented with a small memory footprint thus it's better in tune with the processors and graphics potential of the models in it's day.
10.7+ are fully 64 bit operating systems and require a heft bed of RAM, 4GB minimal and a lot more preferred., it's why I provided the MacTracker info so you can put the maximum RAM into the machine and a faster boot drive, with RAM it's usually MORE can be put in than Apple specifies.
If you can think you can live without 10.7+, then by all means enjoy the performance 10.6.8 gives, at least with that version of OS X you can stick with the hardware that came with the machine. For Snow Leopard Speed Freaks
I say this because a 2008/2009 machine is 5 years old and on it's deathbed far a laptops typically go, so it doesn't have much left in it. It's cooling fins are likely clogged with dust (behind the fans) it's been overheating with the previous owner, the Superdrive is likley worn out and they sold it for a good reason, like that it was going to need a lot of upgrading to bring it to 10.8 only to have 10.9 released in a few months and it will be behind again, or denied being allowed to go to 10.9 or later by Apple due to the age of the machine and unsupported graphics or other reason.
Buying that machine for 10.8+ was not a good choice because of the upgrades required and the poor CPU/GPU performance. It wil run 10.8 of course, just not as snappy as 10.6.8 will be or 10.8 was on your Macbook Air.
If you can live without iCloud, 10.6.8 has over 25% market share still and Apple is issuing security updates but they don't change the version number any longer or give new features.
By the time Apple stops issuing security updates for 10.6.8, that machine likely will be dead of another cause/hardware failure of some sort, most likely the graphics will go on it next.
So I foresee the two events accuring about the same time for you, I see spending more money on that old machine in new software for 10.8 etc., as a complete and utter waste.
If you purchased a used Early 2011 model or later, then I wouldn't have any objection and say go right to 10.8 if it has enough RAM.
OS X 10.4/10.5 need to upgrade, 10.6.8 ok still

Need help with Os X Mountain Lion Installation

I have a Macbook Pro (early 2011) 2.3Ghz and Everytime I boot up my macbook this Os X Mountain Lion screen pop up but when I try to install it. A message pop up saying ‘"temperaly unavailable try again ‘later" and sometimes "please contact apple care". I need help getting pass this installation so I can start using My macbook pro. Can someone help me?

Have you downloaded the Mountain Lion installer from the App Store? It is a stand alone application.

Purchased MacBood Air. Want to install Mountain Lion to our MAC. How do you do that?

I purchased a MAcBook Air, and want to install the OSX Mountain Lion that came with it to my MAC. How do I do that?

You have to purchase Mountain Lion for the other Mac. That's because the Mountain Lion license that comes with the MacBook Air only allows you to install it in this MacBook Air.
In your other Mac, follow these steps to upgrade to Mountain Lion > http://www.apple.com/osx/how-to-upgrade Note that, if you have 10.5 or 10.4, you will have to upgrade to Snow Leopard if it's supported > http://support.apple.com/kb/sp575
Before upgrading, make a backup of your files and check that your apps are compatible > http://www.roaringapps.com

Help! Clean install Mountain lion, nothing happened after entering Apple ID

I have a Macbook Air 11 (mid-2011). Recently I have purchased Mountain lion from App store and upgraded it with no problems. But I would like to have a clean installation to clear all my previous settings and installed Apps.
I pressed 'Option' to restart the computer to Recovery mode, run 'Disk Utility' to erase the harddisk, then clicked 'reinstall OS' to start the installation.
The first few steps look good, when it comes to select a partition for installation, I selected the harddisk and clicked 'Continue'. Then it prompts me to enter my Apple ID and password, I entered it, then the prompt box disappeared with nothing to happen. I then tried to click 'Continue' again, the input box prompted again to ask me for my Apple ID and password, I entered again and, again, nothing happened.
First I thouhg it may be the network problem, so I click 'Continue' again and this time I entered a wrong password. But it can warn me that my password is incorrect, which means the system can actually connect to the internet.
I then opened the log window, and see the following error messages:
localhost Unknown[287]: 2012-08-02 09:29:52.489 Install OS X Mountain Lion[312:1803] Couldn't find app store version, falling back to hardcoded
localhost Install OS X Mountain Lion[312]: Can not connect to /var/run/systemkeychaincheck.socket: No such file or directory
Please help!!
Thanks in advance.

I have had this problem today as well, I phoned Apple and they said it's a known issue that they don't know how to fix it at the moment. I can't get past the grey start up screen with the Apple logo and the spinning wheel. I can get in to the recovery utility but can't download ML.
I went to a repair centre earlier today and they installed it from a disk they had made themselves and it booted twice after that and then died again.
I've booked in for them to call me tomorrow morning so I'll see what they have to say.

Unable to install Mountain Lion on my hard drive

I'm trying to upgrade my early 2008 mac pro from Leopard to Mountain Lion using a bootable usb drive but I'm having trouble doing so. When I try installing mountain lion to my hard drive (Mac Drive 1) - The hard drive is greyed out and says 'you can't upgrade this version of OS X'. Yet it looks like I can install mountain lion onto my second hard drive (Mac Drive 2) for some odd reason.
Here's the details for my mac drive 1 which I'm having trouble with (I noticed the volume format is greyed out on disk utility as well).....
And here's the mac drive 2 info which I don't want to install mountain lion onto but looks like I can....
Any help would be much appreciated! Thanks a lot.

I can't answer the bad hard drive question without some guessing. Not that smart.
Do you have a bootable copy of the Mountain Lion installer?
If not download the following. The site says it will work with 10.6:
http://blog.gete.net/lion-diskmaker-us/
That program will allow you to make a bootable DVD or USB with Mountain Lion on it.
You can boot off of it, erase the disk, and then install Mountain Lion.
I think you should be able to reinstall from carbon copy cloner, but I haven't used that program. During the setup it will ask you if you want to import files, but I don't know if it can read carbon copy cloner. I know it can read a Time Machine backup.
A clean install is generally better anyway.
If you get Mountain Lion installed, not everything works like it did in 10.5/10.6. For an example, scrolling is reversed, but you can change it back to the way it is in 10.5/10.6 in System Preferences. After spending some time in System Preferences, my computer acts pretty much the way it always did.
