Trouble upgrading from Tiger to Snow Leopard

I have a 5 yr old MacBook Pro running Tiger, bought Snow Leopard ($29), was told I could upgrade but I'm not getting proper install screen (the one where you have to check off the "I agree" button, then install, etc).  This is what happens... I pop in the install DVD, a window pops up where I have three options:  1) install Mac OS X, 2) Optional Installs, 3) Instructions.  I double click on "Install Mac OS X", and get another screen with a big "X" that says "Click the button below to restart your computer and begin the installation process", with a "restart" button at the bottom.  When I click "restart", I get an authentication pop up asking me to type in my password.  When I do this, the computer restarts. As the computer restarts, just as it gets to the blue "apple" screen, it spits out the disk. 
Tried restarting holding down the "C" key, nothing happened. 
I've got lots of room and all the requirements, checked all that before I bought it. 
Calling Apple was no help, they said it might be the disk (checked it with "first aid", it's fine) so they're sending me a new one but I doubt it'll make a difference.  I was told it was against their policy to help me through the process as I should have bought Leopard, however if that was still an option I would have bought Leopard first, then Snow Leopard, but I can't get Leopard anymore... don't want to wipe the HD as I no longer have the Install disks that it originally came with. 
Any help would be appreciated!!  I'm no great techie so "dumb it down" for me...

Disk - Disc... lol, knew I'd mess something up
I checked the disc by inserting it into the drive, then going to Utilities > Disk Utility and selecting the Installation DVD disc and then "first aid" to check if it was a bad disc, but it says it's ok.  There were no scratches or anything on the shiny side of the disc and it was a sealed package bought right from the Mac online store. 
When I go to Utilities > Disk Utilities and select my HD, I get options to "Verify Disk Permissions", "Repair Disk Permissions", and "Verify Disk", but "Repair Disk" button is not selectable... don't know if this means something?
My MBP has 1 GB RAM, and 2.16 GHz Intel Core 2 Duo processor so not the one with "issues" from what I see... I would not have bought SL if I didn't meet requirements. 
It wasn't my intention to skip Leopard and go right to SL from Tiger... she was running fine up until a few months ago when I noticed I could only update iTunes and other applications up to a point and now I can't update anything anymore because I need 10.5 or higher.  When I looked into buy Leopard, it was no longer available (nor was the "boxed set" others were recommending).  So now it seems I'm SOL... unless I get it off ebay and I'm not 100% sure buying software from ebay is a great idea.
I've been scouring the forums and sites for answers as to why I'm not even given the appropriate Install prompt screen... no one seems to know the answer to that... At this point, I may just have to suck it up and bring it into a repair shop and pay 10x the price just to fix my baby...

  • Troubles with upgrade from tiger to snow leopard

    I just bought the full SL pack to upgrade from Tiger to Snow leopard but it is coming up with a different interface than my brand new macbookpro that came with sl installed. Is this normal or does it have to do with the fact that the old macbook pro is the first version of the intel macs?

    I see. Your need to drag them to the right side of the demarcation line--the white squares in perspective. They don't work under the line.

  • Want to upgrade from Tiger to Snow Leopard

    I spent over an hour through the apple store web site and cant find a way to upgrade directly from Mac OS 10.4 Tiger to the latest Snow Leopard version.

    this has been oft asked and answered. you can buy a Macbox set which will give you snow leopard, ilife and and iwork. or you can buy a $29 standalong snow leoaprd dvd although there is a big disagreement on the board whether using it to go from tiger to snow leopard directly violates ULA (I think it does). but the actual disk is the same as in the macbox set and either one will upgrade you to SL.

  • I am upgrading from Tiger to Snow Leopard. I keep getting an error when I try to load the Mac Os x update combined. It says that it was corrupted during download. Have try loading from Apple website V10.6.7 upgrade combined but it still won't do it?

    I have an Intel Desktop iMac and I am upgrading from Tiger to Snow Leopard. I keep getting an error when it tries to load the Mac OS X update combined. It says that it was corrupted during download. Have try loading from Apple website  Mac OS X V10.6.7 upgrade combined but it still won't do it? Any other suggestions. The printer is not working either - I am not sure if they are connected. Everything else is fine.

    Please excuse, but I have to ask an obvious question: Did you already update using the Snow Leopard Retail install DVD? (You must do this first; 10.6.7 is just an update if you already have 10.6.) Are you, then, trying to update from whatever version was on the install DVD to 10.6.7?
    Otherwise, I'd keep trying. The 10.6.7 Combo is a huge update.

    Hi,
    the Intel Core Duo processor is a 32-bit only processor and not capable of 64-bit.
    Only the Core 2 Duo and later processors are capable of 64-bit.
    Sorry

  • I want to upgrade from Tiger to Snow Leopard...I'm apprehensive about Lion.

    I've been hearing so many "glitch" anecdotes about Lion. Until these problems are resolved
    I want to upgrade from Tiger to Snow Leopard but I'll be buying a new Apple computer to
    do that..
    I presently have a a 10.4 iMAC with only 2.33 GB of memory and I'm getting a new puter
    in order to have 4 GB. Is it recommended to use Lion with a new Apple computer or can I use
    Snow Leopard without missing out on anything? Are the stories about Lion just the usual thing
    that always happens with a new upgrade? Tiger has worked perfectly for me for 6 years but that
    has been on computer that is 6 years old. (POWERPC) Does a new iMAC computer with intel
    require the latest operating system to work at top efficiency? Is my apprehension about Lion
    an over reaction to anecdotal info?

    Some of this is answered best by knowing what model computers are involved. If you are truly getting a brand new (as opposed to a newer used) computer then it will likely come with Lion installed, unless there's some old stock (which even then would have Lion installed but could still run under Snow Leopard which you would have to buy separately).  Macs will normally only run the version system that comes installed, or newer, so if you are getting a brand new Mac you won't have any choice but to run Lion (or its successors). It won't run Snow Leopard unless it is a new used computer.
    As for Lion stories, those would best be answered on the Lion forum. I still run Tiger which I why I'm on this forum.  There's always issues with any upgrade.  For me the biggest drawback to Lion is all my software is PPC generation and Lion stopped supporting PPC completely. If I got a brand new computer I would also have to upgrade all my software which could easily run to over a thousand dollars more.

    #1 Do a complete bootable backup of your drive before upgrading. That way should anything happen you can revert back to the start and try again.
    Make sure you meet Snow Leopard 10.6 Technical Requirements - http://support.apple.com/kb/SP575
    You might also want to make sure you don't have software issues with SL:

  • Am replacing airport extreme with Time Machine and want to upgrade from Tiger to Snow leopard. Am told I should manually back up into T Machine before OS update but set up utility won't allow anything with OS below 10.5 and I'm 10.4.11. What to do?

    I think you mean you are replacing your Airport Extreme with a Time Capsule. Time Machine is software integrated into OS X 10.5 & 10.6 used to automatically backup a system to an external HD. Time Capsule is an Airport Extreme that has a hard disk integrated into it that can be used for storage or  as a Time Machine backup drive.
    Because you are currently on Tiger 10.4.x you can backup to a external HD using SuperDuper or Carbon Copy Cloner. Having a backup is very wise before doing any major system update. After  you have created the backup and have successfully upgraded to Snow Leopard you can still use the external HD for many things. The strategy I'd recommend is to use the new Time Capsule as your Time Machine backup and then use the external HD as backup using SuperDuper or CCC. Redundant backups is wise because backups can (and do) fail too! In addition both SD and CCC are bootable clones, this is useful in that if your internal HD crashes you can boot from a cloned drive and continue working until the internal HD is replaced.
    Below are some links to some articles from MacWorld, I would recommend reading them where you find a common theme, redundant backups. Backup Plan I, Backup Plan II & Backup Plan III.

  • Problems with Aperture after upgrading from Tiger to Snow Leopard

    Help!  I recently upgraded my IMac operating system from Tiger to Snow Leopard.  Now, I am finding my aperture is not responding the way it used to.  I cannot change the border dimensions; I can't print.  Any suggestions would be appreciated.  I was told by Apple Technical Support that they will not provide support for Aperture 2 and that I would have to upgrade to Aperture 3.  Is this correct? 

    This is called a Kernel panic.
    See here for possible solutions:
    http://support.apple.com/kb/TS3742
    Did you do anything else apart from ungrading OS?
    Did you add memory?
    Bad or not well seated memory modules are often a cause of kernel panic

  • Upgraded from Tiger to Snow Leopard - now have problems with basic apps?

    I have a 2007 iMac (5.1, 2007) dual core. It's capable of running Snow Leopard and Lion (but not, I believe ML).
    I just bought the upgrade SL discs from Apple and installed them as an upgrade, moving up to 10.6.3 (from the discs). After running software update I'm now on 10.6.8.
    Since upgrading I've successfully run Time Machine. However I have the following problems:-
    A bunch of emails were present in the Inbox, but contained no body text - just the subject line. I have managed to since find most of them successfully from TM. This is a minor annoyance but I thought I'd mention it.
    ITunes won't boot up. It booted the first time I tried it, but since then the little icon just bounces up and down.
    Certain apps won't quit properly. I quit from the top menu, but the little blue light remains under the icon in the dock. I then have to 'Force Quit - Application Not Responding' *every time*.
    Safari frequently won't load up bookmarked or seach pages, the progress bar gets stuck part way across and I stare at the rainbow pinwheel for ages, before having to quit, then Force Quit, then restart Safari and try again.
    Now, I'm tempted to do a Clean Install, but after four international moves (Singapore-Australia-UK-Canada) I no longer have any of the original discs, and thus as I understand it will lose iLife. And iLife 11 needs Lion.
    I've done a disc permissions repair thing via the Mac Disc Utility. I've run a few clean-up operations via Onyx.
    Any suggestions gratefully received. My Mac as been running great for years, but this upgrade has been extremely disappointing thus far.
    thanks
    Feargus

    Hi baltwo
    Many thanks for your advice. I've read all the links and will be buying a 2nd external HD to do a SuperDuper back up. I already had a 1Tb drive with Maxtor back up on it, and I also managed to get a Time Machine back up as well, so at least my data should be safe.
    Qn - If I back up the System and Utility folders as well as the Home folder, I don't suppose I can restore them after an install and everything (eg iLife) will 'just work'?
    Anyway, I went straight from Tiger to Snow Leopard. I don't have any Tiger discs either (see reasons above) so now have no way of restoring original set up. I tried to boot from the SL install CD and then hold 'C' but must be getting something wrong as I don't get the Disk Utility pop up. It just boots as normal to the desktop.
    Anyway, via the normal Disc Utitlity I've done a Repair Permissions again with no major issues. However, my Onyx software now won't run at all so I can't clean any caches a second time.
    I've contacted the Apple rep who sold be the SL discs but she's not got back to me yet re iLife.
    This weekend I'm going to try a fresh upgrade. If that fails I'll try Erase and Install, if I can get the 'C' button timing right. I'll update if I have any successs.
    cheers

  • Upgraded from TIGER to SNOW LEOPARD

    Hello,
    How can I uprade from TIGER to SNOW LEOPARD? Do I simply use the upgrade snow leopard to do so? Will that create any instability or issues?
    thank you very much.
    Alex

    Yes, you can upgrade from Tiger to Snow by purchasing the SL DVD. Doing so would only create stability problems if you already have problems, so you should be sure you have a clean system before upgrading. See the following:
    System Upgrade and Installation Procedure
    Basic Caveats
    1. Disconnect all peripherals except the original mouse and keyboard.
    2. Quit all applications if this is not an installation from an Installer DVD.
    3. The installation process should not be interrupted. If a power outage or other interruption occurs during installation you may have to erase the hard drive and reinstall from scratch.
    4. Once the installation begins do not use the computer in any way except to reply to dialog prompts or to restart when the installation is completed. This is especially critical during the installation stage known as "Optimizing the System."
    System Update Procedure
    A. Repair hard drive and permissions.
    Repairing the Hard Drive and Permissions
    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 Installer menu (Utilities menu for Tiger or Leopard.) After DU loads select your OS X volume from the list on the left, 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 (4.1 for Leopard) and/or TechTool Pro (4.6.2 for Leopard) 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. Note that Disk Warrior will not work on Intel Macs.
    B. Clone your existing system to an external Firewire drive.
    How to Clone Using Restore Option of Disk Utility
    1. Open Disk Utility from the Utilities folder.
    2. Select the startup or source volume from the left side list.
    3. Click on the Restore tab in the DU main window.
    4. Drag the startup or source volume to the Source entry field.
    5. Select the backup or destination volume from the leftside list and drag it to the Destination entry field.
    6. Check the box to Erase Destination. Skip this step if you've already formatted the drive.
    7. Double-check you got it right, then click on the Restore button.
    C. Decide upon an installation option (This does not apply to Snow Leopard.)
    You have three upgrade options. If you use the Upgrade installation option be sure you have repaired the hard drive and permissions first and made your backup. If you choose the Archive and Install option then you only need to repair the hard drive.
    Neither of the above options will erase the disk. Some of your software may not work with a new system. You will need to upgrade those programs. It would be best to do the upgrades to your software before upgrading to the new system version.
    Personally, I would erase the hard drive and do a fresh install of Snow Leopard then use Migration Assistant to migrate your old Home folder from the backup. This may take some extra time but is less likely to have problems that may be the result of an upgrade installation.

  • Applications on MacBook run slow since upgraded from Tiger to Snow Leopard

    I have upgraded my MacBook from Tiger to Snow Leopard. After the upgrade, my Mac runs very slowly and it takes several minutes to load a program. I cannot use my graphic softwares and firefox properly, because it takes several minutes to actually start up the application and also to use the application.
    My MacBook states that 45 GB from a total of 110 GB are available space. Do I need to upgrade my HardDrive disk space, or do I need to upgrade my Ram?? What can I do so that my applications/software on my MacBook runs quicker (as they have been prior the Snow Leopard upgrade)?
    Please advise! Details of my MacBook below.
    Processor Name: Intel Core 2 Duo
    Processor Speed: 2.16 GHz
    Number Of Processors: 1
    Total Number Of Cores: 2
    L2 Cache: 4 MB
    Memory: 2 GB
    Bus Speed: 667 MHz

    Hi...If it were my MacBook I would repair permissions via Disk Utility...(in your Applications > Utilities) folder......as well as 'Verify Disk' while you are in the Disk Utility....both functions are under the 'First Aid' tab...single click 'MacIntosh HD' to select it (left column) and then run First Aid.....see what that shows and does first
    Expect some odd error messages while repairing permissions....ignore them...
