Before the install
Ensure your data (at least all Home folders) is backed up before you install. Hard disks can fail at any time so it is important to regularly backup to an external disk with Time Machine or a third party alternative. Inexperienced users should follow Apple's install advice but experienced users may prefer to do a clean install.
OS numbers and names
OS X 10.4.x - Tiger
OS X 10.5.x - Leopard
OS X 10.6.x - Snow Leopard
OS X 10.7.x - Lion
OS X 10.8.x - Mountain Lion

Upgrade to Leopard
Those wishing to upgrade to Leopard should be aware that install disks can be expensive. Details: http://lowendmac.com/deals/best-os-x-leopard-prices.html Standard Leopard installers impose several hardware limitations including speed and RAM size but all these restrictions can be overcome. Google for details. Leopard works well at 500 MHz with 1 GB of RAM and many happy users have less than this.
Upgrade beyond Leopard
OSs beyond OS X 10.5.8 require an Intel processor. If in doubt click the apple at the top left of your screen and select 'About this Mac'. This will give you your OS number. Then click 'More Info' to see which processor you have. If it says PowerPC you cannot upgrade to Snow Leopard and above. If you have an Intel Mac it is well worth upgrading to Snow Leopard now and then considering other options after that. You can buy Snow Leopard here: http://store.apple.com/us/product/MC573Z/A

Is it possible ro clean install Mountain Lion over Mavericks on a brand new mac mini

Is it possible to "clean Install" mountain lion over mavericks on a brand new mac mini

Actually evrything I can find states that the last mini to run SL was 2010.
It appears that the 2012 mini's shipped with Mountain Lion and later Mavericks. Link
Also why would the OP need a bootable SL installation media when they want to install ML?

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.

I had iLife pre-installed on my aluminium Macbook 2009 with OSX Leopard on it. My hard drive broke but got most of the info off it and just installed snow Leopard on to a new drive and then downloaded and installed Mountain Lion over it. Now I don't have iLife anymore. How do I get it back?

Welcome to Apple Support Communities
Mac OS X doesn't come with iLife applications, so you have to install them manually after installing Mac OS X.
Insert the Applications disc or Mac OS X Install Disc 2 DVD and install iLfe applications. Then, open  > Software Update, and install the latest update. If you want, you can purchase iMovie, GarageBand and iPhoto in the App Store, so you will get the most recent version

Hi, I have a late 2008 iMac with a new hard drive. How do I install Mountain Lion from my bootable USB flash drive.

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.

how do i install mountain lion the system will not allow me to "app it" as the Mac OS is older than 10.6

If your Mac is compatible, the upgrade path for you would be to purchase Snow Leopard from the Apple Store: http://store.apple.com/us/product/MC573/mac-os-x-106-snow-leopard
After installing that, you would run Software Update to bring it up to 10.6.8.
Then, you'd access the App Store from Snow Leopard and purchase Mountain Lion.

How do you install mountain lion on all your macs in the household using one 20 dollar license?

how do you install mountain lion on all your macs in the houshold with the same license (you only pay 20 bucks for all your macs) is that right?

As long as they're all logged into the Mac App store with the same Apple ID, you can re-download the installer to all the Macs.
Or you can save a copy of the installer file before you run it and use that to update the other Macs. The ML installer file will appear in your Applications folder when it's done downloading. Copy it to another location (don't move it).
If you don't copy it before you upgrade, it will disappear when ML is finished installing.

I have just installed Mountain Lion over Snow Leopard, I now can't open Photoshop?

Hi everyone, I have just installed Mountain Lion over Snow Leopard. The installation went smooth and woks well. Now I find that Ican't open either Photoshop CS or Microsoft Word. I upgraded in order to install Lightroom 5, obviously there is now an incompatability, is there a work around?

If that is the original Photoshop CS, and Word 2004 or earlier, then they won't open because Lion and Mountain Lion do not support PowerPC apps. They must be Intel code. Snow Leopard could run them because it included Rosetta, a PowerPC to Intel (and back) interpreter.
You have a few options.
1) Go back to Snow Leopard.
2) Update your apps to compatible versions.
3) If you have Mountain Lion because newer apps require it then:
a) Install Snow Leopard Server (currently being sold by Apple for $20) in a VM such as Parallels, and then run your PPC apps in the VM.
b) Install Snow Leopard on a separate partition and boot to that version of OS X when you need to use those older apps.

Hi JoeyR. Well, according to this link at the Apple Store, OS X Moutain Lion became available in July and I downloaded it for $19.99. I figured I would do that before renewing my Norton security SW. Are we talking about the same thing?

Can I install Mountain Lion and Mavericks on same computer

Stupidly I installed Mavericks over Mountain Lion without checking whether Quark XPress 9.5.3.1 would work with Mavericks.
It won't.
I have re downloaded Mountain Lion and need to know whether I can run both on same computer - and how to do that - any help appreciated.
Thanks.

... There is NO way you can have Mountain Lion and Mavericks on the same computer.
Sure you can. Erase one of your partitions and install the OS of your choice on it. You can have as many operating systems on a Mac as you want. Use Startup Manager to select the OS you want to boot. Virtualization software is another option.
Both the Mavericks and Mountain Lion installers will permit you to select the partition on which it is to be installed.
If you don't tell us the errors that resulted from using Lion Disk Maker no one can begin to guess the reason, but no matter, you don't need the USB installer. Just use the App Store.
You can save the installer anywhere you like to use as often as you wish, so you don't have to download it each time.
It looks like this
You have to copy it before running the installer because the installer conveniently erases the 5+ GB file after the installer is finished with it.

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!!

How do I install Mountain Lion AND format the hard drive?

I want to do a completely clean install of Mountain Lion.
I had Snow Leopard installed, upgraded to Mountain Lion (by buying it from the App Store) but how do I tell it to format the drive and then install Mountain Lion?

Snow Leopard would have needed to be installed on a properly formatted drive, so I don't understand why you would need to format it again to that same format.

How do I install mountain lion but keep snow leopard as a bootable os

I'm caught in a vicious circle.
I need mountain Lion to be able to use iCloud and to be compatible with a couple of apps on my iPad. However some of my major apps on my mac Pro won't work under Lion or mountain lion.
SO the answer is to have both Snow Leopard and Mountain Lion on my Mac Pro.
Does anyone know of any instructions on installing Mountain Lion onto one SSD, whilst leaving Snow Leopard on another, allowing me to boot from either.
Also - any advice on the cleanest way of installing my apps under Mountain Lion (those that are compatible). I'm confused to how I can install my apps twice, especially if I have all ready registered Unser Snow Leopard.
Thanks

I'm assuming that you currently have an SSD with Snow Leopard on it, and another SSD with no operating system. Is that correct?
What I would do is use the Snow Leopard DVDs to install a fresh copy of Snow Leopard on the SSD that currently has no operating system, and "migrate" your data and applications from the other SSD. (alternatively, you could use something like Carbon Copy Cloner to duplicate one SSD onto the other - but that's probably only an option if one SSD is completely blank or you're willing to erase it).
Then upgrade to Mountain Lion on the original SSD.
When you're done, hold down the option key when you start up to select which OS to use.
For many applications, it won't matter which SSD they're on - you'll be able to run them from either system without worrying about where the app is installed (each will have it's own preferences, stored on the current startup drive). But some applications are more complex, and rely on additional files that are scattered around the Library folders on the startup drive. Since you migrated your applications and data, you should have everything that's needed on both systems, including license keys, etc. I did this for a little while with Quicken, and I actually left the Quicken app on the Lion drive - it worked just fine even though I started up from an external Snow Leopard drive (I skipped the migration step entirely, and reentered my Quicken license code when starting up from Snow Leopard).
How successful this will be depends on exactly which applications you're using. Most of them will be OK, but if you're using something that has some esoteric copy-protection mechanism, you might run into a little bit of trouble. Consider upgrading the "new" Snow Leopard install to Mountain Lion, if that's the case, so you're original system SSD will remain Snow Leopard, with no changes.
