Force Install of Snow Leopard on MacBook Pro

I purchased a used MacBook Pro from IBM where I worked until a few days ago. I got the laptop and it has been erased by some disk utility that IBM uses to wipe the disk clean. I try using the Option button to boot to the disk utility but it seems that absolutely nothing is left on the MacBook. When I boot using the Option key, it brings up a screen with two options. One looks like a hard disk that has the word WINDOWS underneath it and the other looks like a CD called MacOSx Install DVD. Under that, I can choose a network. When I click on the DVD, it just sits and does nothing. From reading other posts, it seems that I must wipe the partitions off the hard disk first and then the DVD will start the install. However, I do not know how to ge the disk utility and/or whatever IBM did to this thing disabled even the disk utility. I called Apple last night and made an appointment to do a force install but looking at posts, seems I should be able to do this myself with the right key strokes and order of things. I'm brand new to Mac. Does anyone know how I can verify if the disk utility still exists on the Mac? Wouldn't that be in the BIOS or in Ring 0 of the hard drive? Did IBM wipe it out, too or something?

You have to find out the exact model of the machine then erase and install the operating system that came with it from the factory or 10.6 earliest.

How to install upgrade snow leopard in macbook pro?

I bought a macbook pro 2011 2.2 ghz quad core i7 and would like to install snow leopard in one partition to run older software. I had the full version of os leopard, but can't install in the new macbook pro to upgrade to snow leopard. I can't upgrade snow leopard in my power G5 either because it needs intel cpu. Is there away to upgrade leopard to snow leopard in macbook pro 2011? I have not bought the snow leopard upgrade yet. Thank for your help.

See the bottom of this user tip to determine if Snow Leopard can be installed on your MacBook Pro:
https://discussions.apple.com/docs/DOC-2455
If it can, you'll need to find out the version of Snow Leopard installer that was available at the time that machine was released based on the age of the machine.
Snow Leopard releases are here:
10.6.6 on January 6, 2011
10.6.7 on May 4, 2011
10.6.8 on June 23, 2011

Can't install Snow Leopard on Macbook Pro MC700 - 3 beeps after installer starts.

can't install Snow Leopard on Macbook Pro MC700 - 3 beeps after installer starts (10.6.3 retail). Lion installer starts normally. What's a problem?

I have the same trouble, I try installing rEFI but when I try start my Pro from DVD doesn't recognize.
Can I start from USB Memory? with files from SL DVD? or have some thing else?
I have original DVD of SL 10.6.3, if I buy the latest stable version, can I install? or the EFI firmware with Lion change again?
I try to use Lion, more than one week but I can't, and some app that I use for my profession, doesn't work, I really need downgrade to SL.
Really Thanks for any help.

The certificate on my applications install DVD for bundled software has expired. I am unable to reinstall with this dvd on my snow leopard on macbook pro. Pl help. If I use Lion, it works fine with the expired certificate. But doesnt work with snowleopard.

Create a DMG file of your DVD (instructions here: http://www.wikihow.com/Make-a-DMG-File-on-a-Mac).
Then follow the instructions here: http://managingosx.wordpress.com/2012/03/24/fixing-packages-with-expired-signatu res/

Cannot install snow leopard in macbook pro early 2011. disk is rejected. what do I do?

Unable to install snow leopard in macbook pro early 2011. When I put in the disk, the computer does not accept it. What can I do?

lord1908,
some Early 2011 MacBook Pros originally came with Snow Leopard installed, and some originally came with Lion installed. If yours originally came with Snow Leopard installed, then you should be able to install Snow Leopard from its model-specific grey Mac OS X Install DVD. (The white retail Snow Leopard DVD can’t be used with it; it was made for use with earlier models, which originally came with either Tiger or Leopard installed.) If yours originally came with Lion installed, then it won’t accept any Snow Leopard DVD; instead, you’d be able to use OS X Internet Recovery to download and install its original version of Lion from Apple’s servers.

How to install Snow Leopard on Macbook Pro? keep getting msg- cannot install Internal HD is used for Time Machine- this was reset to external HD and still get msg?

At some point, your internal HD was selected for use as Time Machine backups, and a Backups.backupdb folder was created at the top level. So OSX thinks you're trying to install it on the same drive as your backups.
Open your internal HD with the Finder (you won't find it via a Spotlight or Finder search) and delete that folder.

Can i run snow leopard on macbook pro puchased new in 2009?

Can I run snow leopard on macbook pro purchased new in 2009?

The Snow Leopard 10.6 DVD should still be available at this time from Apple for $20. You will have to call Apple Customer Care 1-800-692-7753 or 1-800-676-2775 to purchase it. It may still be in the Legacy Products list. The App Store which is required to download 10.7 Lion or 10.8 Mountain Lion is part of the 10.6.6 update.
If you wait to long and they no longer have any in stock you will have to buy it from eBay or Apple resellers that still have stock. But you will have to pay a premium since the DVDs are no longer being made. Snow Leopard DVDs are already over $100 on Amazon.

Install OS X 10.6 Snow Leopard on MacBook Pro problems

Hi all,
     About early November, I upgraded my MacBook Pro (Mid 2009) but failed to restart it. The spin sign stayed there for a very long time and nothing happened more.
     So I decided to reinstall the OS X 10.6 with a CD ordered from Apple with the MacBook Pro, but the installation stopped and reported failure after a few minutes. Then, I tried to format the hard disk (Toshiba 250G), but it reported either "Input/output error" or "Could not allocate memory". I thought my hard disk may be broken, I bought a new one (Hitachi 750G) but still can not format the disk with same errors.
     After search related topic in the community, I took the internal hard disk out and mount on my Desktop (Mac Pro, OS X 10.5.8) through USB port, I could format both the hard disks (Toshiba 250G & Hitachi 750G). I followed one instruction about "Installing Snow Leopard onto an External Hard Drive" (Dan Hinckley, Maciverse) and installed the OS X 10.6 on one hard disk (Hitachi 750G) through my Desktop Optical Driver (Booted on the DVD).
     I mounted the hard disk (Hitachi 750G) on my MacBook Pro and could run the system. Then I decided to move this external hard disk into my MacBook Pro as an internal hard disk, however, when the MacBook Pro started, it showed a STOP sign (one circle with an oblique line) and several quick flashes of Apple icon, then reported some error messages like below (I list some of them),
   "Panic CPU0 Caller", "Unable to find driver for this platform", "SourceCache Debugger Called", etc.
     What shall I do next,
      1 Install the OS X 10.6 one more time when the hard disk (Hitachi 750G) inside my MacBook Pro, booting from DVD through Optical Driver.
      2 Get the hard disk (Hitachi 750G) out and mount as USB external again and update to higher version of OS X (but which version?).
      3 Other suggestions?
Thank you!
Bart

I purchased a Macbook Pro on Nov 2 2011 which was pre-installed with Lion and I'm trying to install Snow Leopard on it. It won't recognise my SL Install Disc at all and just hangs so I wiped the drive and attempted to start up from a bootable SL memory stick. I got an audible alarm from the Macbook Pro which would only stop when I restarted the computer. I had to re-install Lion from a Time Machine back up via the internal recovery disk. I'm pretty sure that late 2011 MBP will not take SL but I'm waiting for a Firewire 400 to 800 cable to arrive so I can try to wipe the internal drive entirely and install via Target Disk mode. I'm not hopeful but I gotta try as I need Snow Leopard to run Pro Tools and other programs. If only I'd bought it before October 24th this wouldn't be happening!!!!!!!!!!

Snow Leopard in Macbook Pro 9.2 (mid 2012)

Hi!!! I need to install Snow Leopard in my macbook pro 9.2.
I Have made the instalation in any kind of macbook pro (versions 5,6,7,8) but I can´t do it in my 9.2.
What I get in Verbose mode is:
Loading system library caches com.apple.kext.caches startup extensions.mkext........
and then it stops.
I´m doing the installation with a Snow Leopard 10.6.7, because it´s the version that runs with Ivi Bridge.
I have tried with differents Hard Disks and even with 1333Mhz RAM (the 9.2 have 1600Mhz).
What can I do?? because I need to run the Snow Leopard at all cost
Thanks

Exactly why do you need to run Snow Leopard on your new MacBook Pro?

Original install disks may be obtained from Apple. Give them a call and be prepared to give them the serial number of your MBP. There is a charge.
Ciao.

Can't install Snow Leopard on MacBook Pro - DVD won't mount

I am unable to install Snow Leopard on my MacBook Pro as the DVD won't mount. This is an early 2008 vintage MacBook Pro, intel core duo...
I'm using a OS X Snow Leopard install DVD (family licensed). This DVD has been used to install 3 other Macs in my house without a problem (about a year ago), but cannot be used to upgrade my MBP. Actually, this disk mounted on the MBP exactly once - inserted with system up, the disk mounted. Upon running the installed (a year ago), the computer restarted but hung in boot. After getting the disk ejected and the computer restarted, the disk would never mount again. I've defered upgrade for a year but at this point need to upgrade my MBP at least to Snow Leopard and possibly Lion.
The problem doesn't seem to be with the DVD, since it continues to mount fine in other computers, and in fact a borrowed Snow Leopard DVD also will not mount on the MBP.
BUT ... the problem also does not seem to be with the optical drive in my computer, as it can read & mount the install/restore disks that came with the computer as well as other CDs and DVD ROMs. Only the Snow Leopard install DVDs fail to mount.
I've also tried mounting the 10.6 install DVD on my Mac Pro desktop, making it available over the network (ethernet) with DVD/CD sharing. I can mount the remote disk from my MBP that way, but when I launch the installer, the application launches (its own menus are displayed, I can quit from menu, for example) but does nothing -- no windows open, nothing.
I've also tried "Remote Install" (again with the DVD made available with the Remote Install MacOS X application on my desktop), but when I boot the MBP with option held down, the remote disk is not available as a startup disk.
Zapping the PRAM did not help.
Am off to the store to get an optical drive cleaning kit and a blank DVD big enough to burn a new disk image, but would appreciate any further ideas at this point....

Solution that worked: Copy the Install DVD to a USB flash drive and boot from that.

Up and running with Snow Leopard now and working on the updates.

How to re-install Snow Leopard on Macbook Pro i7?

When using a retail copy of Snow Leopard DVD I get "Unknown CPU" error.
I tried to install it by moving the HDD onto another (older) macbook. But then when I move the HDD back, I get the "Unknown CPU" error again. I do not have the original DVD that came with the i7 Macbook Pro.
Thanks,
Roman.

Thanks! That actually worked.
Didn't work for Macbook Air, naturally, though, since Air doesn't have an HDD case.
