How To Create A Mountain Lion NetRestore Image
In previous versions of OS X this was not an issue. In Apple's atempt to "simplify" things it has become more difficult. I have a NetBoot server set up with OS X 10.8.2. I created a custom image on a MacBook Air. I booted to the recovery partition and used disk utility to capture the image of the custom machine. When I try to use System Image Utility on the OS X server to prepare my image for NetRestore, it is greyed out with red next to is stating it has to have a recovery partition. I even used Apple's Recovery Disk Assistant to create a recovery partition on the same disk that holds the custom image but it doesn't reccognize that. Has anyone else been able to do this with no problems?
You will need to either connect to the MacBookAir with an ethernet adapter, or create your image on an external drive. The recovery partition is created during the OS installation process, is required to create a netwok image, and is not preserved via the method you used.

How do I download Mountain Lion to the other computers at my home without additional cost? I downloaded 10.8 to my main IMac but have two additional computers in my home.?
Install 10.6.8 on the other computers. Sign into the App Store with the same Apple ID used to purchase Mountain Lion. Click on the Purchases icon in the toolbar. Locate your Mountain Lion purchase entry which will show an active Install/Download button to the right of the entry. Click on it to download to the computer. If you don't wish to download Mountain Lion twice, then do this:
Make Your Own Mountain/Lion Installer
1. After downloading Mountain/Lion you must first save the Install Mac OS X Mountain/Lion application. After Mountain/Lion downloads DO NOT click on the Install button. Go to your Applications folder and make a copy of the Mountain/Lion installer. Move the copy into your Downloads folder. Now you can click on the Install button. You must do this because the installer deletes itself automatically when it finishes installing.
2. Get a USB flash drive that is at least 8 GBs. Prep this flash drive as follows:
Open Disk Utility in your Utilities folder.
After DU loads select your flash drive (this is the entry with the mfgr.'s ID and size) from the left side list. Click on the Partition tab in the DU main window.
Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID then click on the OK button. Click on the Partition button and wait until the process has completed.
Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
Set the format type to Mac OS Extended (Journaled.) Click on the Options button, check the button for Zero Data and click on OK to return to the Erase window.
Click on the Erase button. The format process can take up to an hour depending upon the flash drive size.
3. Locate the saved Mountain/Lion installer in your Downloads folder. CTRL- or RIGHT-click on the installer and select Show Package Contents from the contextual menu. Double-click on the Contents folder to open it. Double-click on the SharedSupport folder. In this folder you will see a disc image named InstallESD.dmg.
4. Plug in your freshly prepared USB flash drive. You are going to clone the content of the InstallESD.dmg disc image to the flash drive as follows:
Double-click on the InstallESD.dmg file to mount it on your Desktop.
Open Disk Utility.
Select the USB flash drive from the left side list.
Click on the Restore tab in the DU main window.
Select the USB flash drive volume from the left side list and drag it to the Destination entry field.
Drag the mounted disc icon from the Desktop into the Source entry field.
Double-check you got it right, then click on the Restore button.
When the clone is completed you have a fully bootable installer that you can use without having to re-download Mountain/Lion.
Note: The term Mountain/Lion used above means Lion or Mountain Lion.
As an alternative to the above you can try using Lion DiskMaker 2.0 that automates the process. -
How do I install mountain lion not as an upgrade
Hi,
I'm running OS 10.6 on my computer. I'd like to upgrade to mountain lion. But instead of installing it over the existing system, I want to format my computer and start it fresh. How can I do that?If you are running Snow Leopard (10.6.x), update to the latest version of OS X Snow Leopard before you purchase OS X Mountain Lion from the Mac App Store. Click the Apple icon and choose Software Update to install Snow Leopard v10.6.8, the latest version.
When download of Mountain Lion is complete cancel the installation and you may create an installation disk from downloaded source.
How to do it you may find here
Or
Install it on top of existing system and if there is something that you do not like and think that clean install would make it better, you may start your computer from recovery partition created by Mountain Lion installation, reformat your disk and do clean install. -
How do I install Mountain Lion on a thumb drive?
How do I install Mountain Lion on a thumb drive when my computer is running Mavericks? I downloaded the Mountain Lion installer, but when I attempt to run it I get a message that says "You cannot install OS X 10.8 on this computer." I don't want to install it on the computer, I want to install it on the thumb drive—but it won't give me a choice of drives.
The reason I want to do this is I want to be able to boot my iMac into Mountain Lion in order to test a hardware/software combination I suspect might be incompatible with Mavericks.
(Note: there are plenty of instructions online for how to create a bootable thumb drive with the Mountain Lion installer, but that's not what I want. I want to install ML on the thumb drive itself.)Sure you have a proper installer application. When I start it I get:
Clicking on Continue, then accepting the licensing stuff, gets me to:
If you click on Show All Disks, then all mounted disks will be presented including your flash drive.
Now the above is a Mavericks installer, but it's the same for Mountain Lion. -
How do I download Mountain Lion for free?
I purchased my MBP in July last year. I need to create a bootable drive of OS. In the app store, it is not showing OSX Lion. There is only the option of downloading Mountain Lion, but that isn't free.
If I am correct, I am entitled to a free upgrade, right? How do I download Mountain Lion free of cost? I want to have a bootable drive at hand, just in case my MBP goes kaput, like it did about 10 days back.
Any help would be appreciated.No, unfortunately that was the Up-To-Date Program and I think you're a bit late for that. Right now ,the only available DL is Mountain Lion and it's no longer free.

Does anyone know how to update OSX Mountain Lion 10.8.1. to 10.8.2. on a late 2012 Mac mini. All I get are 'not compatible' messages even using supplementary updates etc?
It appears that many of the problems with the HDMI are the "monitors" that are being used. Samsung and Vizeo both DO NOT support a computer input on HDMI only VGA. There probably are others, manuals must be read to confirm compatability.
I strongly believe that the reason the 10.8.2 update was pulled is due to the fact (it happened to me) that the new Disk Utility creates a Fusion drive if aftermarket SSDs are added to the system. I think Apple wants this propriatary Fusion Drive to be something you buy from them not a "homebrew" for lots less money. -
How do I download Mountain Lion?
I am currently running Leopard (OS X 10.5.8) and am having trouble finding where do download Mountain Lion. The website says to download from the Mac App Store, but I don't have that. How do I download Mountain Lion?
because I want to be able to create a bootable thumb drive.
Unfortunately, you can't do that with the App Store version. As mentioned, that version of ML will not work with your Mac as it will not contain the necessary hardware drivers. The App Store version is intended only for users upgrading from Snow Leopard or Lion.
You really can't make fully restorable boot copy of Mountain Lion. The Recovery Disk Assistant Csound1 linked to is as close as you can get. What you end up with is a bootable disk that behaves exactly the same as the Recovery partition. It's still not a full copy of the OS. Most of it will have to download from Apple's servers.
The only way to have a fully restorable copy of ML is to clone the entire drive to an external drive and leave it alone. Boot to that drive only when necessary to restore it to a hard drive you've replaced in your Mac, or as another drive to boot to when their's trouble with the main drive. -
Mail created w/ mountain Lion will not open in SL10.6.8, or OS X yosemite.
Mail created w/ mountain Lion will not open in SL10.6.8, or OS X yosemite. How can I convert it to open?
After a second call to AppleCare, they had advised me differently than before. Once they found out that my personal computer has Mac OS X Lion installed from the App Store, they suggested I simply upgrade my parents computer to Lion.
So, I used my download from the App Store and upgraded. It went smoothly, but Mail still will not open properly. And instead of the original error message, it comes up with this:
"Check with your developer to make sure Mail can work with your version of Mac OS X. You may need to reinstall the application. Check if there are any updates available for the application."
How can I re-install just Mail? A startup disk is not accessible for me right now. Can I download the latest version of Mail and install it from the Apple.com website? -

How can I download Mountain Lion onto an external disk?
Hello everyone
My macbook pro hard drive was failing and at a genius appointment the technician said I could either pay for them to do the replacement or do it at home, since it would cost me nearly three times less. I bought the hard drive which is physically installed but my mac was not working before the replacement so I couldnt create any copies of the content, sofware, etc which means that now I have no idea how to install the sofware again... I've read about downloading Mountain Lion off the Apple Store onto an external disk and then rebooting the Mac from the external disk but I cant use my apple ID on any other Mac that isnt mine so I'm totally lost... Any help, please?I'm assuming the grey disks are installation CDs that came with the mac?
Correct. But since you're trying to get back to Mountain Lion, you don't need them. If you had created a Mountain Lion bootable flash drive from your original download, you could have started up to that and installed ML directly.
Since it appears you don't, than what you do need is a retail Snow Leopard disk. If you don't have one, it can be purchased directly from Apple for $20. Install that and update it to at least 10.6.6 to get the App Store app on the drive. Then you can login to your App Store account and retrieve and install Mountain Lion. -
How do you erase mountain lion to install snow leopard?
Hi, My mother now has a new to her late 09 mini that originally shipped with snow leopard. When she bought it it came with mountain lion preinstalled from a private seller. We were thinking that to be on the safe side that it might be better to erase and install what's on it just to be sure it is secure. I tried to erase and install snow leopard from a disk but it says that the installer is not compatible with this version of osx(mountain lion). Question: How do I erase mountain lion and install snow leopard?
I've read here that there is possibly a built in recovery disk that I can use to erase and reinstall mountain lion. Q: Is there a built in recovery disk available in my situation? and if so should I use it or be even safer by installing snow leopard instead?
Thank you,I think I found the answer (from sl install disk use disk utility to erase then install sl). Thanks for looking.

I do not have a high speed internet connection. How can I get Mountain Lion on a disk for install?
I do not have a high speed internet connection. How can I get Mountain Lion on a disk for install on my 24" Imac?
As long as you use your Apple ID to purchase it, I don't see why they wouldn't let you download the installer on one of their Macs and put it on a pocket drive.
Or, a friend with a high speed connection?
I agree with you about the delivery method, just trying to help you get what you want. -
How do I redownload mountain lion for a clean install on the same machine without purchasing again?
I purchased mountain lion and upgraded my OS. The system seems to still be having some issues and I'd like to do a clean install with the new OS. How do I redownload mountain lion so that I can make a bootable disk and do my clean install?
You should be able to just go to the App Store and select Download again. If that doesn't work, try holding down the option key while selecting "Buy".
Good luck,

How do I install Mountain Lion to a new hard drive without having the recovery partition on it.
I have the USB flash drive with software on it but when I switch my Mac on all I have is a white screen & a flashing question mark.
ATB,
Steve.Did you use LionDiskMaker or DiskMaker X?
Boot the machine with the option key down until you see your bootable USB stick. Select the latter, and reboot.
When the installer boots up, you will first need to choose Utilities and Disk Utility. Select the target HD device name and then the partition tab. Select 1 partition, name it Macintosh HD. Format is Mac OS Extended, and option is GUID. Apply. Exit Disk Utility and return to the installer, which will now show your newly partitioned HD as available for install.
When OS X is installed and all updates applied, press shift+command+U and run disk utility again. Verify/repair permissions and verify the boot disk.
