I used my snow leopard disk to erase my hard drive. Now I want to eject the snow leopard disk to clean install from the lion boot disk I made. How do I eject the snow leopard disk? It is the start up disk and I can't figure out how to get it out of the computer so I can put my lion boot disk in. Thanks

turn the mac all the way off. turn the mac on by pressing the power button. as soon as the apple logo appears, pres and hold your mouse button(trackpad mouse clicker etc...) until the CD comes out.

many thanks Carl.

You must boot from another drive in order to erase the system drive.
Try starting up with Snow Leopard DVD inserted and C depress. That should get you booted from the DVD. Then start Disk Utitlity from DVD and erase the disk then you should be able to install Snow Leopard.
Remember that everything will be removed from the disk when you erase it and install Snow Leopard so backup first.

I had to change my Hard Drive, now I want to work on files in iWeb, but can't access Time Machine before yesterday. The dates are there on the right hand side but are greyed out before yesterday when I changed my HD. How do I access anything from before.

Disk Utility - Erasing a hard drive using MS-DOS (FAT)

Hi all,
I have recently purchased a 500GB external hard drive. I have used Disk Utility to format the drive from NTFS to MS-DOS (FAT) so I can use it with Windows PC's as well as Mac's.
My issue is this.
I copied a 1.16GB file over Firewire 800 to test the speed and then deleted it. After deleting the file the info pane still reports that 1.17GB of the drive has been used.
Why is this?
Thanks!
David

Did you remember to empty the trash can? If not, the file is in the hidden directory .Trashes on the Windows drive. You don't reclaim the space until you empty the trash.

I have a 750 GB SS Hard Drive that was in my Macbook pro 15", i am trying to install it into my new Macbook 13" and when i power it, the apple sign comes on but stays on that screen. Can anyone tell me what Steps i missed.

I need help trying to get my Macbook Pro 13 to bootup.

The software that comes from the factory, pre-installed has always only contained the drivers for that specific model and no others.
If you want to install on a different model Mac, you need to have the original installation DVD or go back to Recovery_HD and download again.
Your 13" and 15" have somewhat different Hardware, and you need the correct version for that model or a purchased or downloaded version to proceed.

I have erased my hard drive, now when i'm trying to re-install mountain lion i can't see the hard drive in DU. Any ideas on how to restore this?

Try the following document:

If that doesn't work, this site has a lot of info on hard drive problems:

I'm personally betting that the first link will fix your problem. The second link has a book you can download that has a lot of reset and troubleshooting information on it.

Do a backup, preferable 2 separate ones on 2 drives. Boot to the Recovery Volume (command - R on a restart or hold down the option/alt key during a restart and select Recovery Volume). Run Disk Utility Verify/Repair and Repair Permissions until you get no errors. Reformat the drive using Disk Utility/Erase Mac OS Extended (Journaled), then click the Option button and select GUID. Then re-install the OS.

When you reboot, use Setup Assistant to restore your data.

I would like to know if after I erase all my data, empy hard drive inside the macbook, the time machine will erase all my files that I have saved in my "WD "My passport" external hard drive

Welcome to Apple Support Communities
Time Machine has to erase the external disk in order to make backups. Before setting Time Machine up, copy the files of your external disk to the hard disk of the Mac in order not to lose them, and then, set up Time Machine. The first backup will start automatically.
If you want more information about Time Machine, read the Pondini's site > http://pondini.org

How do I restore my operating system from Snow Leopard back to Mountain Lion on line after erasing my hard drive?

I had to erase my hard drive. I loaded Snow Leopard with the disk I got with my computer, but I purchased Mountain Lion several months ago and don't have support any longer. How do I get back to the Mountain Lion operating system, on line?

Upgrading to Snow Leopard
You can purchase Snow Leopard through the Apple Store: Mac OS X 10.6 Snow Leopard - Apple Store (U.S.). The price is $19.99 plus tax. You will be sent physical media by mail after placing your order.
After you install Snow Leopard you will have to download and install the Mac OS X 10.6.8 Update Combo v1.1 to update Snow Leopard to 10.6.8 and give you access to the App Store. Access to the App Store enables you to download Mavericks if your computer meets the requirements.
     Snow Leopard General Requirements
       1. Mac computer with an Intel processor
       2. 1GB of memory
       3. 5GB of available disk space
       4. DVD drive for installation
       5. Some features require a compatible Internet service provider;
           fees may apply.
       6. Some features require Apple’s iCloud services; fees and
           terms apply.
You must perform the last step - updating to 10.6.8. Until then you have no access to the App Store. When you can sign into the App Store using the same Apple ID with which your purchased Mountain Lion, click on the Purchases icon in the toolbar. Locate your Mountain Lion purchase line then click on the Install button on the right to re-download.

I have a Mac Pro with four hard drives. I currently have Lion installed on one hard drive. I want to have the option to boot from either Lion or Snow Leopard. How can I do this?

I have a Mac Pro with four hard drives. I currently have Lion installed on one hard drive. I want to have the option to boot from either Lion or Snow Leopard. How can I do this?

It's best to install Snow Leopard on one of the three remain drives without an Operating System.
You can then install the applications you need from the original media. Create a User Account using Setup Assistant.
Do you want to migrate User Accounts from the OSX LIon boot drive, or are you keeping the User Accounts separate?
Dual-booting just requires holding the option key during startup and selecting either Lion or Snow Leopard.

I need to erase my hard drive. But the drives are grey when I go to Disk Utility.

Restart the computer with the Command and R keys held down and use the Disk Utility from there. If you're going to sell or give away the computer, press Option as well.

I have a WD 2 tb hard drive that I want to use to back up my Mac Pro quad core. How do I create a back up startup disk? Also, when I used Time macine, it only backed up users and not the system or library folders. Ideas?

Time Machine should be enough to make a backup of your files. Also, it should back up all folders, so open System Preferences > Time Machine > Options, and make sure that there are no folders included in the excluded items list.
If you want to create a bootable clone of your hard drive, you need to use an app like Carbon Copy Cloner or the Disk Utility's Restore feature > http://pondini.org/OSX/DU7.html
