Hey folks,

 

 

thinking about going back to SnowKitty. (I miss it. A lot.). Currently I have Mountain Lion, 10.8.4.

 

I currently have a 10.6.3 retail disc, and when I try to boot from the disc, I get the dreaded Three Beeps of Death.
(Tapping Option during Boot, then selecting the disc, or holding C both result in the Beeps).

 

 

I have heard that I MUST have the Gray Discs (Recovery Discs) to truly go back to Snow Leopard from my current ML version of 10.8.4.

 

However, a Tier 1 Apple Tech Support guy just told me (on an official call) that if I

 

- Go into disc utility in ML

- Erase my main HDD

- Pop in my Snow Leopard Disc

- Boot

 

that I will be able to install it without any problems.

 

I kind of wondered about this solution before he told me about it... my obvious fear is that in so doing this, I will again go to boot into

the 10.6.3 disc and get the Three Beeps of Death--but now my HDD will be erased and I will be totally hosed.

 

Thoughts on this?

rogueguineapig: If you can't find the gray disks, use an older Mac to install 10.6.3 onto an external drive and then run the 10.6.8 combo updater on that system. This will give a definitive answer on whether or not it's possible without them.

1. Yes, it does.

2. Use a program such as the Disk Utility, Carbon Copy Cloner, or SuperDuper to move it to a blank partition on the internal drive.

    It isn't possible to revert on that Mac model.

    You use the DVD that originally came w/your computer, DVD#1.  To reinstall the OS, you use DVD#2.

     

    Clicky click--—> Erasing disks securely

     

    ================

     

    Start up from your install disc, go to Disk Utility and select the disk and click erase - to securely erase data click Security Options and Erase Free Space which will entirely wipe your disk, overwriting it with zeros so that no data is recoverable.

    Late 2011 MBPs came with Lion pre-installed. Basically, you cannot install Snow Leopard on that model. Furthermore, three beeps at startup means you have bad memory, not the wrong installer disc. Whoever advised you on the telephone gave you bogus information.

     

    Even if you could boot the computer from a version of Snow Leopard, it would be foolish to erase the drive. It would make more sense to create a new partition on the hard drive on which to install Snow Leopard. In this way you have both operating systems running in a dual-boot arrangement.

     

    I would leave well enough alone.

    Three beeps at startup can mean that the disk is too old. If it was a RAM issue, it would happen every time the computer was started up, not only when an attempt is made to boot it into a specific OS version.

    Hey Baby Boomer,

     

     

    I don't have my Gray Restore Discs/DVDs handy at the moment (trying to find the **** things),

     

    and the Snow Leopard disc that I DO have is the retail 10.6.3 disc.

     

    So what I'm asking is: if I erase my HDD through Mountain Lion Disc utility, will that retail disc work to install
    10.6.3 Snow Leopard, or will it refuse to boot, leaving me with an empty hard drive and no OS?

     

     

    EDIT: I might add, my MBP Came with Snow Leopard...it did not come with Lion originally.

    I think it was probably one of the VERY last ones with Snow... I remember the Lion release coming out like a week after I got this thing.

    Where did you read this, Niel? I don't recall having done so.

  • Kappy Level 10 Level 10

    You don't have those discs because none came with that model. Baby Boomer is right about some earlier models, but not about yours.

    I recall hearing what Niel said... the three beeps means the drivers are too old for that particular model.
    I just can't recall where...I've been reading dozens of threads here...

    Niel, do I need a completely clean external drive to do this? Is it possible to use a USB drive to do that?

     

    After it's installed on that external drive, and then booted into, and updated to 10.6.8,

    then what? What's the MO for moving it over?

     

    and by the way, thank you all for the advice and answers!

    Regardless, you cannot boot your model from a retail Snow Leopard DVD. You did not get any gray labeled discs with your computer because it came with Lion pre-installed. You cannot install Snow Leopard on that model as much as you would like to (unless you have a different, earlier model that did come with Snow Leopard from the factory - Early 2011 or earlier.)

    Thanks, but I must confess not remembering seeing this in other threads. I was hoping perhaps you knew of an Apple article explaining it. Thanks, anyway.

  • Niel Level 10 Level 10

    1. No, the drive doesn't need to be blank.

    2. It can be an USB or FireWire drive.

    3. Plug the drive into that computer and start it up with the Option key held down.
