Even more amazing, Apple didn’t configure the installer to do any checking for qualifying installed versions of Leopard, so the upgrade version works just like a full install version, with one little exception. Previous versions of OS X had installers that could perform various types of installations. The most popular types of installations were ‘Erase and Install’ (sometimes called a clean install), ‘Archive,’ and ‘Upgrade.’ The Snow Leopard installer has no option for performing any type of installation other than an upgrade, but with a few extra steps, you can get it to perform an ‘Erase and Install’ for you. Erase and Install The secret to performing an Erase and Install is to manually erase your hard drive using Disk Utility before you install Snow Leopard. To do this, you will need to perform the following steps. Boot from the Snow Leopard Install DVD. Erase the hard drive.
Install Snow Leopard on the erased hard drive. Once the Snow Leopard DVD mounts on the desktop, the Mac OS X Install DVD window should open. If it doesn’t, double-click the DVD icon on the desktop. In the Mac OS X Install DVD window, double-click the ‘Install Mac OS X’ icon. The Install Mac OS X window will open and present you with two options. You can continue with a standard upgrade installation, or use the utilities included on the install DVD.
Click the ‘Utilities’ button. The Snow Leopard installer will inform you that in order to use the supplied utilities, you will need to restart your Mac and boot from the DVD. Click the ‘Restart’ button. Using Disk Utility from the Snow Leopard Installer.
After you reboot your Mac, the Snow Leopard installer will ask which language you want to use as the main language. Make your selection and click the right arrow key. The Install Mac OS X screen will display.
Click the ‘Utilities’ button. In the Apple menu bar, select ‘Disk Utilities’ from the Utilities menu. Disk Utilities will launch. Select one of the following instructions, depending on what you wish to do. Use these instructions to erase an entire Be sure to back up all of your data first.

Complete the Snow Leopard Installation To complete the installation, follow the instructions in That’s all there is to it. You now have a clean installation of Snow Leopard that mimics the ‘Erase and Install’ option available in previous versions of OS X. Accessing the Mac App Store At this point you may be asking yourself where is the Mac App store that was suppose to be included with OS X Snow Leopard? Actually the Mac App store was not part of the original version of Snow Leopard, but was added in OS X 10.6.6. To gain access to the store, you may need to perform an update to your system software. You can do so by selecting Software Update from the Apple menu.
Hello and welcome to my User Tip You need to erase and install 10.6 Snow Leopard, I will show you how to do this. If your here because you upgraded to 10.7 Lion and want to go back to 10.6 Snow Leopard you need to see this thread. A little more preparation is in order to make sure your files work in Snow Leopard. If your here because you have a problem and you think erasing and reinstalling is going to solve it, it most certainly will, but you might not need to go this far and you might want to recover data off the non-booting drive first. If your here because you want to secure erase data better than writing Zero's acorss the selected hard drive or partition (good enough for most folks), this tip doesn't cover that, see this one then come back here afterwards. Use the correct 10.6 disk to install Snow Leopard Use the free MacTracker to find your model of Mac, you can gleam the model from your Apple Menu About this Mac More information and look for something like 'MacBook Pro 3,1' and punch that into MacTracker. There are basically two types of 10.6 install disks, the gray or black machine specfic ones that came with a new Mac (free iLife) or the 10.6.3 retail disks (no free iLife).
You can't use another model of Mac's 10.6 machine specific disks with another Mac, there isn't hardware drivers on those disks that will work on other Mac's. If a Mac came pre-installed or from the factory with 10.6.3 or later, you cannot use the 10.6.3 retail disks (no iLife) from Apple online, you have to call Apple for your 10.6.3+ machine specific install disks (free iLife included) Ready to erase and install Snow Leopard? Your data will be gone after this and not recoverable what so ever, don't come crying later that you missed something.
You might want to take this chance to export web browser bookmarks, grab product keys or even clone the old 10.6 drive before you erase it. Unmount and disconnect all other drives. Make sure the bottom of the disk is clean, use a very soft cloth and a tiny dab of rubbing alcohol and polish to a shine. Hold c (or option/alt key) down on a wired or built in keyboard, and boot the machine, off the 10.6 installer disk (or hold option key boot off the 10.6 clone drive) and under the Utilities menu (folder) is Disk Utility. To erase the entire drive of all partitions: Select the entire internal boot drive on the far left, it will have the drive makers name and size. Do not select the indented names, those are just partitions on the drive, you need to erase the entire drive to catch everything, rebuild the GUID partition table and the hidden EFI partition. If your here to revert your machine to Snow Leopard from 10.7 or later, then make sure to select the ENTIRE drive on the left in Disk Uitlity.
To erase just the OS X partition leaving others like Bootcamp etc. Select the indented name of the OS X partition instead, however it will not cure problems in the hidden EFI or GUID partition table.
Do not do if your reverting to Snow Leopard from a later OS X verison, because 10.7 and later OS X verisons alter the GUID and add a Recovery HD partition that needs to be removed before 10.6 is reinstalled. This is so later when you need to use the 10.6 disk to repair the drive, it knows what is on the boot drive. Click Erase Security option Zero All Data (will map off any failing sectors) go watch a movie, it takes a bit and improves your hard drives reliability and read speeds. (SSD no need zero, just erase). Trust me this works wonders!
If the Disk Utility Zero Erase fails or hangs, the drive has run out of spare sectors and is worthless, it will have to be replaced, better you found out now than later with your data on it. Check under Partition: Options that you have a GUID and Format: OS X Extended Journaled, if not change it to those and apply. Quit Disk Utility. You will be back into the 10.6 installer. Fresh installing Snow Leopard 10.6 If your using your option key bootable 10.6 clone, use the cloning software to reverse clone 10.6 onto the internal drive then return your files from the storage drive.
Your done, see you later. Now for you who just erased the internal drive via the 10.6 disk and need to install fresh.
'Fresh' means no possibly corrupt TimeMachine, Migration Assistant, or clone restores. New OS X, programs and only vetted files returned. Performance types swear by this method as it allows the leaving of previous junk, malware, old files etc behind. Trim and speedy. 1: Quit Disk Utility and install 10.6.
From the installer disk. Reboot, setup and use the same user name as before. (different password ok) Why?, because you can place your user files from backup right on in and your iTunes playlists, permissions etc work. Unless you don't want to use the same name, then you lose the playlists and have to recreate them, change the permissions for files. 2: Use Software Update to get up to 10.6.8 fully, repeat until clear. This is very important to do or you'll have problems later. 3: Install Rosetta for your PowerPC based programs Insert the Mac OS X installation disc that came with your computer or with your Mac OS X retail package.
Double-click the Optional Installs folder, and then double-click the Optional Installs package. A package has an icon that looks like an open box. Follow the onscreen instructions. Select the disk where you want to install Rosetta and click Continue. Select the checkbox next to Rosetta, click Continue, and then click Install. 4: Install all third party programs from fresh original sources and compatible with 10.6.8 If by chance you get a hang upon reboot after installing third party software, hold the shift key down upon booting and update or remove the problem software, you will know, you just installed it.
If you had 10.5 previously on the machine, you'll notice your iLife is missing with the 10.6 install. This is because the 10.6.3 disk doesn't have it, only the machine specific disks do that come with the Mac when it was new. You can either buy the 10.6 iLife from Apple or use Pacifist from CharlesSoft to extract the 10.5 versions from the 10.5 install disks. You paid for it so it's yours. 5: Once you have all your third party software installed (as best as you can of course) next is to hook up your storage drive. Return the contents of those user files folders: Music, Pictures, Movies, Documents etc (not Library) to their respective folders in each account Apple support doc on installing 10.6 again Hard drive performance tip If you installed exactly in the order as I have outlined above (1, 2,3,4), and keep your boot drive below 50% filled, it will operate at peak performance forever until it dies, or you damage it by moving it around while it's operating. Your hard drive performance will suffer greatly the more OS X boot partition data is written on the second 50% of the drive, even if you remove some to get under 50%.
If there is any data on the second 50% of the drive, the heads have to travel there to get it, use the smaller sectors and that slows read/write performance on hard drives (SSD no need to worry). Whatever you do, don't go past 80% filled on boot drives on Mac's as your pressing your performance and stability luck.
Problems installing? 1: Hold the power button down to hard shutdown. 2: Hold the option key and trackpad button/wired left mouse button down (wired or built in keyboard might be needed) and boot the machine. 3: The disk hopefully should pop out, if not when you get to Startup Manager, keep pressing eject on the keyboard. 4: Take some rubbing alcohol (a tiny bit) on a soft clean cloth and polish the bottom of the disk, when dry and blemish free, stick it in and when it appears, click the arrow key to boot from it. 5: Review your secure erase procedures here to make sure your not leaving data 6: Try to reinstall 10.6 again 7: If that fails, call Apple and tell them what Mac you have and see if you require MACHINE SPECIFIC Snow Leopard install disks. (10.6.4 -10.6.8) These disks also include the free iLife suite on them.
The 10.6 white retail disks sold online are 10.6.3 and won't work in your machine due to a lack of more recent hardware drivers not present on those disks also they don't contain the free iLife suite. Apple might also have 10.6.0 - 10.6.3 machine disks as well if you need the free iLife, but they could take longer to come than the 10.6.3 white retail disk. 8: After install, just hard shutdown and it will boot to the 'Welcome' video for the next owner. Advanced options 9: If Apple is going to take too long to send you disks or won't, there is a option to create a image of the bad disk and burn a new one on another Mac (possibly on a PC too) as a ISO image. Sometimes when the read and burn occurs, errors are repaired and the new image will work when the old one won't. 10: Another option is to create a Snow Leopard boot USB from the 10.6 disk, then boot and install with that.

Snow Leopard (OS X 10.6). Courtesy of Apple The default installation method for Snow Leopard (OS X 10.6) is an upgrade from Leopard. If you prefer, you can erase your hard drive and start fresh with a (in fact, I highly recommend that method), but in this step-by-step guide, we’ll perform the basic upgrade installation. What You Need to Install Snow Leopard.
An Intel Mac. Snow Leopard only supports Intel-based Macs; it does not support older PowerPC Macs.
If you’re not sure which type of Mac you have, use the FAQ to find out. A Mac running Leopard (OS X 10.5). The upgrade version of Snow Leopard that was first made available will only perform upgrades and clean installs on Macs that already have OS X 10.5 installed. Apple will release a full install version of Snow Leopard soon. The full install version will allow you to install OS X 10.6 on any Intel Mac, regardless of the OS that’s currently installed. 1 GB of RAM. More is better, but Snow Leopard will run on a Mac with 1 GB of RAM.
5 GB of free space on your startup drive. Snow Leopard actually uses less hard drive space than older versions of OS X, but you need 5 GB of free space for the installation to complete successfully.
A DVD drive. If you have a MacBook Air that doesn’t have a DVD drive, you will need to use a network or an external USB DVD drive to install Snow Leopard. Gather everything you need and let’s get started. The Snow Leopard installer.
Before you insert the Snow Leopard Install DVD into your Mac, take a bit of time to prepare your Mac for its new OS. A little advance housekeeping will ensure a quick and uneventful installation. The housekeeping chores we recommend will also make it easy for you to revert to your previous OS, should a problem occur during installation or should you need an older version of OS X to run an older application. Detailed instructions are available in the guide.
Once you finish (don’t worry; it doesn’t take long), come on back here and we will start the actual installation. Select the destination drive for the Snow Leopard installation. Now that we’ve taken care of all the boring housekeeping chores, we can get down to the fun part: installing Snow Leopard. Install Snow Leopard. Insert the Snow Leopard install DVD into your DVD drive. The Mac OS X Install DVD window should open.
If it doesn’t, double-click the DVD’s icon on your desktop. Double-click the ‘Install Mac OS X’ icon in the Mac OS X Install DVD window. The Mac OS X installer window will open. Click the ‘Continue’ button. Select the destination drive for Snow Leopard.The selected drive must already have OS X 10.5 installed. Click the ‘Customize’ button if you want to make any changes to the packages that will be installed. Most users can skip this step, as the default packages should prove adequate, but if you want to add or remove specific installation packages, this is the place to do it.
For example, you may want to remove languages you don’t need or make changes to the printer drivers that are installed. Snow Leopard uses a new method for installing and using printer drivers. Previous versions of the Mac OS installed a long list of drivers that most of us never used. Snow Leopard’s installer checks to see which printers are attached to a Mac, as well as which printers are nearby (connected by a network and using the Bonjour protocol to advertise that they are on the network). If you want to install all available printer drivers, expand the ‘Printer Support’ item and put a check mark next to ‘All Available Printers.’ Click ‘OK’ when you’re done. When you’re ready to proceed with the default install, click the ‘Install’ button. The installer will ask if you’re sure you want to install Mac OS X.
Click the ‘Install’ button. The installer will ask for your password. Enter your password and click the ‘OK’ button.
With these basic questions out of the way, your Mac is ready for the actual installation. The installation progress bar. With the preliminary setup out of the way, the Snow Leopard installer will start the actual file copying.

It will present a status window that displays an estimated time to complete, and a progress bar that provides a visual clue to how much work is yet to be done. Copy and Restart Once the Snow Leopard installer copies the core files to your hard drive, your Mac will restart. Don’t worry if you stay at the; this process can take a little time. I waited for what seemed like at least three minutes, although I didn’t actually measure it. Eventually you will return to the installer screen and the status bar will reappear.
The installer will continue to copy necessary files, as well as configure the, getting it ready for your use. Once this process is complete, the Snow Leopard installer will display a new window announcing that the installation of Snow Leopard was completed successfully. You can click the ‘Restart’ button and start using your new OS.
If you went off to take a coffee break while Snow Leopard was doing all the work for you, your Mac will restart on its own after a minute. Pressing the ‘Continue’ button is the final step of the installation.

After you install Snow Leopard, your Mac will go through its first restart and then either bring you to a login screen or directly to your desktop. Once you reach the desktop, there will be a short wait as Snow Leopard performs a few background tasks and then launches the Max OS X Setup Assistant. Setup Assistant The Max OS X Setup Assistant will display its welcome screen and play a bit of music. Once the welcome animation is over, the Setup Assistant actually has nothing to do, because you upgraded from a previous version of OS X and there’s nothing more to set up.
