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!!!!!!!!!!

Installing Snow Leopard on Macbook Pro problem
The fine writing on the bottom of this Mac is almost gone but it looks like A1276, if not then A1278. Anyway, I replaced the dead HDD on this MP Model A1276 with a new sealed 500GB Toshiba SATA HDD. In Disk Utility, I select the HDD and click on ERASE but I am getting an error message
Disk Erase Failed with the error:
POSIX reports. The operation couldn't be completed.
Cannot allocate Memory?
Help please?Here's how it should be done:
Drive Partition and Format
1. Boot from your OS X Installer Disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu.
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area. If it does not say "Verified" then the drive is failing or has failed and will need replacing. SMART info will not be reported on external drives. Otherwise, click on the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Apply button and wait until the process has completed.
4. 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.
5. Set the format type to Mac OS Extended (Journaled.) Click on the Security button, check the button for Zero Data and click on OK to return to the Erase window.
6. Click on the Erase button. The format process can take up to several hours depending upon the drive size. -
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).

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. -
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 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.

They are probably about the same based on benchmarks.

Can't install Snow-Leopard on Macbook pro (Midd 2010)
Hi there,
i have i big problem, i can't install a retail-version from snow-leopard (Version 10.6) on my Macbook pro.
Follow Situation: yesterday i get the Developer-Preview from Lion and install it onto my productiv-system. Not a good idea, i know, but i have a backup and will back to Snow Leopard. So, i try to start the Retail-Version DVD and she start, but only to the gray Apple-Symbol. Then they stop and don't go away.
I try to reset the PRAM, the SMC, no result. I try to start the installation from a USB-Image, same result. I try to start the installation from another harddisk/partition, the same result.
When i press cmd-v at the start i can read, that they stop after the load from the extensions.kext.
I have a Problem, a big Problem, i know. But what can i do?You will need to use the system disk that shipped with your unit, the build is most likely different then the one on the retail version
Then after it is installed- you can use the migration assistant to import your data from your backup.

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.

Hey,
O.K. I've got a brand new unibody 17" MacBook Pro. It's loaded to the hilt, and I paid a fortune for it. Unfortunately, it's a **** good-looking paperweight.
After only 51 re-cycles on the battery and several weeks of usage, I bought it in August, it's become almost completely unusable. The "service battery warning indicator" shows up all the time, it shuts down randomly at what appears to be sufficient battery life remaining, and it burns battery power like crazy while in sleep mode. This has all occurred after upgrading to Snow, ah-hum," b-l-o-w" leopard.
The big kicker is that I can't seem to downgrade to any other previous verision of OS X. The computer simply will not allow me to install an OS other than Snow Leopard now.
It is my strong belief that Apple has either acquired a large number of faulty batteries or that Snow Leopard has a major bug in it!
Since Apple will delete this post unless I ask a question, etc. etc....
I ask this: Does anyone have a solution for this? What can be done to fix the issues I mentioned here.
It is my strong belief that Apple has either a serious bug in SIf you're relying on a plainly defective battery to power your computer for much of the day nearly every day, it's certainly no wonder you're having trouble. Get the bad battery replaced, then determine whether you still have problems. You likely will, because all those unexpected hard shutdowns may have scrambled your hard drive directory for fair. Use Disk Utility's *Repair Disk* function to straighten it out as needed, calibrate your new battery properly, and then see whether your computer works as it should. Don't fool around trying to reinstall the operating system until you see what a new battery will do for you. And don't use a retail Leopard installer DVD if you do reinstall the OS: it won't support all your MBP's features. You need to find the DVD that came with the machine or use your Snow Leopard installer DVD, one or the other.
