Help with Snow Leopard "Re" Install on Macbook Pro

I have a 2010 Macbook Pro.  Upgraded to Lion.  No problem.  Last week, things got a little glitchy.  A long download for iPhoto (among other things) would not work.  I thought, why not upgrade to Mountain Lion.  I purchase.  Download... yet its not working, download corrupted.  Tried again and again.  Nothing.  Tried to search some possible solutions, made it worse.  System acted weird.  Thought I should restart.  Turned off.  Would not start.  Attempted safe mode start, bar goth 30% across screen, off.  Put old Snow Leopard install CD in, booted from that.  Started.  Can't revert, but previously backed up important files, so I erase Mac HD.  Pain in butt, but at least I'll start fresh, so I think.  Every time I go to install from CD, it gets to the same 33 minutes to go and then and error happens saying it can't install the necessary support files.  ???  What is going on?  I'm prepared to scrap and replace the physical hard drive (not the first time, had a similar problem on my still going strong Mac Mini from years earlier.  I just want to know if I'm doing something wrong, am I erasing wrong?
Suggestions appreciated greatly.  I just want my laptop to work again!

Well, you have a mess.
Connect the Apple 10.6.3 DVD.
Reboot MBP with option key held down.
Choose SnowLeopard DVD
When DVD boots into install, choose Disk Utility from main menu
Choose the MBP drive in Disk Utility
Partition, 1 partition, option GUID, HFS Plus, Journaled
In Disk Utility FIrst Aid, Verify the Drive
Exit Disk Utility, but not installer
Start the Install from the Snow Leopard DVD
On reboot, follow additional setup procedures.
Choose Software Update, to get 10.6.8 updater and other files.
Go get coffee.
When updates are done, backup your MBP with TimeMachine.
Done.

  • Snow Leopard already installed on Macbook Pros?

    I know this may seem like a stupid question but cut me some slack, I've never had a mac before.
    I just bought a brand new MacBook Pro today. It came with a disc "Mac OS X Snow Leopard". Is this disc already installed on my computer or do I have to insert it and install it? It also came with two grey discs entitled "Applications Install DVD" and "Mac OS X install DVD". Are these also already installed? Thanks!

    It's confusing. The disc just says "Mac OS X Snow Leopard". It doesn't say what version it is. It does say 1. Instal such and such, however I'm a PC user and usually the discs that come with the computer are already installed, they are just backup incase your computer has some sort of problem.
    Actually I did just see on the front of the "Everything Mac" handbook it says, "10.5.7 Leopard" but, not knowing a mac, I wouldn't know if that was any different.
    Do I have to install those grey discs as well?

  • Should I upgrade to Snow Leopard/ Lion using a MacBook Pro with 2.26 GHz Inetl Core 2 Duo Processor and 2GB Memory? Can my old macbook take it?

    Should I upgrade to Snow Leopard/ Lion using a MacBook Pro with 2.26 GHz Inetl Core 2 Duo Processor and 2GB Memory? Can my old macbook take it?
    thanks

    Yes. You should be fine with Snow Leopard, but Lion requires a minimum of 2 GBs of RAM. If you upgrade to Lion I would first upgrade your RAM to at least 4 GBs if your model supports it. Also, see:
    How to Install OS X Updates Successfully
    A. Repair the Hard Drive and Permissions:
    Boot from your current OS X Installer disc. After the installer loads select your language and click on the Continue button. Then select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list.  In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive.  If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer. Now restart normally. 
    If DU reports errors it cannot fix, then you will need Disk Warrior (4.0 for Tiger) and/or TechTool Pro (4.5.2 for Tiger) to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
    B. Make a Bootable Backup Using Restore Option of Disk Utility:
    Open Disk Utility from the Utilities folder.
    Select the destination volume from the left side list.
    Click on the Restore tab in the DU main window.
    Check the box labeled Erase destination.
    Select the destination volume from the left side list and drag it to the Destination entry field.
    Select the source volume from the left side list and drag it to the Source entry field.
    Double-check you got it right, then click on the Restore button.
    Destination means the external backup drive. Source means the internal startup drive.
    C. Important: Please read before installing:
    If you have a FireWire hard drive connected, disconnect it before installing the update unless you will boot from this drive and install the update on it. Reconnect it and turn it back on after installation is complete and you've restarted.
    You may experience unexpected results if you have installed third-party system software modifications, or if you have modified the operating system through other means. (This does not apply to normal application software installation.)
    The installation process should not be interrupted. If a power outage or other interruption occurs during installation, use the standalone installer (see below) from Apple Downloads to update.  While the installation is in progress do not use the computer.
    D. To upgrade:
    Purchase the Snow Leopard Retail DVD.
    Boot From The OS X Installer Disc:
    Insert OS X Installer Disc into the optical drive.
    Restart the computer.
    Immediately after the chime press and hold down the "C" key.
    Release the key when the spinning gear below the dark gray Apple logo appears.
    Wait for installer to finish loading.
    E. If updating:
    Download and install update(s) 
    Use Software Update, or
    Download standalone updater(s).

  • Do i need to install snow leopard on my new macbook pro?

    i picked up a new macbook pro and it came with snow leopard. i don't know what the snow leopard will enhance and if i should even install the program.

    Your MacBookPro comes with Snow Leopard pre installed. It's not a program, it's an operating system. Mac OS X - Snow Leopard.

    How can I install Snow Leopard on my 15" MacBook Pro without using its DVD drive?

    I'm assuming your dvd drive is broken? if you have a thumb drive large enough (8GB or better), you can use another computer to make a bootable image from the install dvd to the thumb drive. then you can install from the the thumb drive.

  • Macbook Pro with snow leopard pre-installed

    Does anyone know when the retail apple store locations will have the 13inch MBP pre-installed with snow leopard? i called up the local apple stores in my area and they still dont have these yet, maybe they need to get rid of old stock? i understand that snow leopard comes pre-installed when purchased online but i dont want to do that.

    Welcome to Apple Discussions!
    Are you sure? You realize if you ever find a software title that is not Snow Leopard compatible, but is with older versions of Mac OS X, and you buy a Mac with Snow Leopard prebundled, there likely will be no way of going back to Leopard or earlier. This has been the case with all new Macs once they come prebundled with a new operating system.
    Unless you are 100% certain of Snow Leopard compatibility, I would be happy to have this reprieve.

  • I am trying to do a clean install of Snow Leopard on an Intel Macbook Pro. (Need to partition for Boot Camp)  I have done it in the past so I know it works but whenever I select the install disk as the boot device it gets stuck on the Apple logo/pinwheel.

    Prety much what the question says. HELP!

    If you just stuck the disk into the Leopard Mac and run the upgrader, you didn't do a "fresh install" you basically upgraded from 10.5 to 10.6 leaving all the programs and files intact.
    The white Snow Leopard disk was the right one for that machine as it had Leopard (10.5) on it previously.
    So you already have Snow Leopard installed, if you want to erase the entire drive (along with all your programs, files and OS X) and want to install Snow Leopard again, you hold the c or option/alt key down and boot the machine off the disk. Then use Disk Utiltiy to erase the entire drive, then quit and install Snow Leopard.
    How to erase and install Snow Leopard 10.6
    Once Snow Leopard is installed you log in and use Apple Menu > Software Update until clear to get to 10.6.8 and fix security issues.
    Now I can't get it to do the install again.
    To install Windows into BootCamp, you read and run the BootCamp Assistant located in the Applications > Utiltiies folder
    It's important to change the drive format from FAT32 to NTFS before installing Windows using the Windows disk.
    Windows is rather complicated to install, if you boot to a blinking line with "press any key to continue" you need to press and hold the power button down and reboot holding the Option/Alt key down to get back into OS X.

    If your Windows programs are not going to be as CPU/GPU demanding, you may rather prefer to use a virtual machine instead
    Windows in BootCamp or Virtual Machine?

  • Can i install snow leopard on my new macbook pro

    I'm looking at a new laptop but I understand Adobe CS4 won't work on Lion, so I'd rather install Snow Leopard on the new macbook. Is this possible?

    Difficult, and even reported "success" is likely not consistent enough for your *need* for Adobe CS4.
    You can try for a unit off the refurbished list (Apple.com > Store, bottom of the left hand margin is the link).  Units from pre-July and last year can be found, and come with warranties just like brand new.

  • Need help with Snow Leopard compatibility issue

    We have a new iMac in (with Snow Leopard) and have loaded all our programs. Due to budgets, we have not made the jump to CS4 and are still on CS3 (waiting for 5). We work in an InDesign/InCopy workflow.
    In launching InDesign on the MAc with Snow Leopard, we have noticed that the assignment folders are nonexistant and within the program you can't even open an assignment window. When you reopen on a system without Snow Leopard, the individual assignments are there, but the program states it can't find the main assignment, so it's cancelling out the assignments if opened on the Snow Leopard unit.
    Does anyone have any info on compatibility issues with Indesign CS3 and Snow Leopard? My tech guy found nothing on this before we ordered the new system.

    First things first. CS5 was announced today and preorders are being accepted.
    I believe if you upgrade to CS4 you'll get a free copy of CS5. This is important because if you're upgrading a suite, tiered pricing makes CS3 to CS4 $200 less than waiting til CS5 comes out.
    That out of the way, is everyone fully patched to CS3 5.0.4? Is Snow Leopard fully updated to 10.6.3? Do you have full read/write permission on the server?

  • Snow Leopard 10.6 on MacBook Pro 2,1

    As the title suggests, I'm trying to install 10.6 on my MacBook Pro 2,1. I am getting into iPhone dev with a few of my colleagues, and one of the requirements is 10.6. However, when I previously tried installing the OS it told me it could not be installed on my computer due to my 32-bit EFI or something like that. I have read numerous accounts of people running Snow Leopard successfully on their MacBooks, an I am wondering what I am doing wrong.
    System Specs:
    Model Name: MacBook Pro 17"
    Model Identifier: MacBookPro2,1
    Processor Name: Intel Core 2 Duo
    Processor Speed: 2.33 GHz
    Number Of Processors: 1
    Total Number Of Cores: 2

    Memory: 2 GB
    Bus Speed: 667 MHz
    Boot ROM Version: MBP21.00A5.B08

    Thanks a Lot.

    You probably are not running the retail disc, or have enough space, or migrated from PowerPC the migration assistant. The retail disk looks like *
    Of course you should always backup your data at least twice before installation

  • Can I install Snow Leopard on the latest Macbook Pros? (the ones pre-loaded with Lion)

    The problem and solution is pretty simple, I just want to know if anyone has tried this before. I have a brand new Macbook Pro that I bought more or less for the sole purpose of having a more powerful machine to run AVID Media Composer on. AVID is only compatible up to OS version 10.6.7 at the moment, and the machine I got was pre-loaded with Lion, 10.7....So I look at the support documentation Apple provides, and notice that in the nifty little chart they have, the latest line of Macbook Pros out there (early 2011) originally had version 10.6.6, so I'm assuming that's the previous version I can't downgrade past.
    To revert back to Snow Leopard, however, I need to install it from the DVD which has version 10.6.3 on it, and then upgrade to any version between Snow Leopard 10.6.6 and Lion 10.7. In theory this could work, the only problem being that for a brief time between installing Snow Leopard and updating to the version of it that I need, the computer will have version 10.6.3 on it.
    Now I'm pretty sure if the only thing I do on the computer is immediately update to a safe-to-use version, there will be no problems. However, if the machine's hardware is so terribly non-backwards compatible with the Snow Leopard OS, I may do all this backing up and reverting and not even be able to start the computer once I get the old install on it. Before I just go ahead and try this for myself, I was wondering if anyone else has, and more importantly, have you had any success?

    Hi r,
    EDIT: disregard my post. Waiting for that disc is a far better option.

    Now I don't mind if some drivers are messed up and resolution is all funky when I install 10.6.3 on it, I just need to know if it'll be functional to the point where I can run the 10.6.6 update dmg. Once I update to 10.6.6 everything should work fine.
    Or could I install 10.6.3, have the 10.6.6 update burned to a disc, and boot straight from that? This is my first Mac so I'm not sure what little tricks work or not.
    Your first idea may work; the only way to know for sure is to try it. If you do, make sure you download and run the Combo update for 10.6.7 or 10.6.8. There can be different versions of a point update, those which are available for download, and those which ship on Macs, so you want to install one beyond that which shipped with some of the new MBPs.
    If the MBP won't boot to 10.6.3, something else to try is installing it to an external HD, then installing the 10.6.7 update on it, clone it to the MPB's internal HD, and run the 10.6.7 or 10.6.8 Combo update on it.
