    My sister lost her systems disc and her HDD failed on her. She's going to ship me her computer and I was going to install a new HDD and Snow Leopard onto it from the system disc/upgrade disc that I got when I ordered my MBP in mid 2009 and got the 10 dollar upgrade to Snow Leopard for buying a new system.

    I recently restored my MBP just using the Snow Leopard upgrade disc rather than using my older systems disc (installing Leopard and then upgrade to SL)

    What happens if I use my systems discs on another Mac? Will there be a problem?

    System discs are produced specifically for the computer they were supplied with.

    If system discs discs are lost etc, replacements are only available direct from Apple for a nominal charge.

    if you and your sister have the exact same model, it will work. otherwise see John T's post.

    But this is the Supplement SNOW LEOPARD disc that I received about 2 months after I got my laptop. It's not the SL retail version though I don't think... I was able to just do a fresh install with it though the other day. Rather than upgrade it from Leopard like I thought I was supposed to.

    Can it be used on more than one computer?

    Yes. The grey discs that came in the box only work on the model you purchased but the Snow Leopard disc they sent you should work on another Mac.

    Not to the exact computer but rather the exact type. So you could use them on a different MBP as long as its the same model. You cannot use the gray discs from a MBP on an iMac however.

    Hmm.... I've used my MBP disc on my Macbook Air.... I wonder what is the specialization that makes them theoretically incompatible with one another?

    No idea. Nor do I now the level of granularity. I mean does the discs for a 13" MBP work for a 15"? I know that they don't work when going to a different computer line, iMac to Mac Pro, and such

    There might be a problem, but then again, if you do things right, there might not be.

    VERY IMPORTANT QUESTION:
    Does the Mac she's sending you have firewire?

    If the answer is YES, the following might help:

    You might be able to boot HER Mac into "firewire target disk mode" and then install a clean system to it. Try this:
    1. Have the two Macs side-by-side, and have a firewire cable at-hand
    2. Power down BOTH Macs completely, ALL THE WAY OFF.
    3. Connect the firewire cable
    4. Power up HER Mac, and IMMEDIATELY hold down the "T" key, and KEEP HOLDING IT DOWN.
    5. You should get a "firewire icon" on HER Mac's screen - this indicates it's booted into target disk mode
    6. Now boot YOUR Mac using the system install DVD that came with it. Insert the DVD, press the power-on button, and IMMEDIATELY hold down the "C" key and KEEP HOLDING IT DOWN. You should boot to the installer
    7. You will first need to open Disk Utility (which I believe is under the "Tools" menu bar when booted from the install DVD, and re-initialize HER Mac's internal drive
    8. Now you can go to the installer, and begin the installation process (as if you were going to do the installation to YOUR OWN Mac). BUT -- at the appropriate moment -- you need to switch the disk to HER disk which should appear in the installer's list of volumes to which you can install to.
    9. Let the installer do its thing. When done, you're going to have to power down at the appropriate moment, or "pull the firewire cable" when HER Mac reboots (after the installation is complete)

    Now boot HER Mac up -- see what happens. Do you "get a good boot" (and get to the "Welcome to Mac" video?)

    If you don't, oh well, at least you tried (see closing comments below).

    But if you DO get the "Welcome to Mac" video, IMMEDIATELY create a new administrator account (I suggest you ask her in advance how she wishes that account name/password to be), and then go to Software Update and run the available updates.

    When they're all in and installed, see if you can reboot.

    If you can, you're home. You made it.

    Closing comments:

    How much is it going to cost her to "ship" her Mac to you, and how much will it cost to ship it back to her?

    Wouldn't it be a lot easier for her to simply spend $29.95 and buy the Snow Leopard install DVD and do it herself?

    AFAIK, those discs are like the retail OS discs in that they don't contain the iLife apps (iPhoto, iMovie, iWeb, iDVD, Garage Band).

    Why do you want to steal the reasonably priced $29 Snow Leopard?

    Well I'd rather not pay for what I can just install onto her computer if I already have it. Also my sister is not computer savvy... her HDD is dead for all intents and purposes. I'd probably just swap it out with one of my old drives and then install Snow Leopard for her... here's another question though...

    Even if i were to buy a retail copy of Snow Leopard...

    I thought you could only upgrade to Snow Leopard if you were already on Leopard, her computer was on Tiger and she had never upgraded.

    Will there be an issue?

    UPDATE:
    Just googled... never mind, you can... I never knew...
