I can't upgrade to Snow Leopard from Leopard

I have a MacBook Pro that came with OS X 10.5.8 installed. It also came with a disc containing Snow Leopard. I never got around to installing it until now, because I'd like to upgrade to Lion.
When I try to install Snow Leopard, I get a yellow triangle with this message: Mac OS X Snow Leopard cannot be installed on this computer.
I have an Intel Core 2 Duo processor, 2 GB RAM and plenty of available disc space. Any idea why it won't install?

The Option I was talking about was this, see if it has this...
Start up from your Mac OS X Install Disc 1 or Install DVD. If you have different versions of Mac OS X Installer discs (for example, if your computer came with version 10.3 and you later purchased and installed version 10.4), start from the disc that most closely matches the installed Mac OS X version. Usually, that's the latest (newer) version.
Usually, you can start from the disc by putting it in your computer, restarting, and holding the C key. Or, put it in the computer and click the Install or Restore icon you see in the disc's main window (after which the computer will start from the disc without you needing to hold C.)
Select your language. The Welcome to the Mac OS X Installer window appears.
Click Continue. The Important Information window appears.
After reading or printing the information, click Continue. The Software License Agreement window appears.
After reading or printing the information, click Continue.
An agreement sheet appears. If you agree with the license agreement, click Agree. The Select a Destination window appears.
Click the volume that you wish to install to.
Click Options. The installation options sheet appears.
Select Archive and Install.
Select the volume which already has Mac OS X installed.
You should also select Preserve Users and Network Settings, to preserve network and Home directory settings. (See notes and Related documents below.)
Click OK.
Click Continue to begin the installation.
Ah yes, that is an iMac only Disc...

Can I upgrade to Mountain Lion from Leopard for free?

Hi Apple Support,
I was in the Apple, Covent Garden store the other day and an assistant said that I could upgrade to Mountain Lion from Leopard for free in one CD. He told me to call a number which I did and the assistant over the phone had no idea about this offer.
Can someone dispell the confusion for me?
Thanks

You can't. The Mountain Lion upgrade is only free for people who purchased a new Mac on or after July 26 without it installed, and all of the computers which fall into that category shipped with Lion, not Leopard.

Prohibitory icon after upgrading to snow leopoard from leopard

I have done an upgrade from Leopard to Snow Leopard on several iMacs a Mac Book and a Mac Book Pro to prepare for an upgrade to Lion. The install disk installed 10.6.3. I then did software update to upgrade the system to 10.6.8. This went fine on most Macs but on an iMac and the Mac Book Pro I now get the prohibitory icon when I start them up. I can however start them up in Safe Boot mode by holding the Shift key after the start up chime. Some times If I start-up in safe boot then shut down and then do a regular startup the Mac will start up. Then just to be sure things are working I will do a couple of restarts then eventually the prohibitory icon is back. The problem with trying to troubleshoot this is the inconsistent nature of the problem, some iMacs upgraded fine, one did not and the MacBook Pro did not. Sometimes the Macs with the problem will restart, sometimes not.
I have tried several things.
Zapping the PRAM,
Repairing permissions with Disk Utility.
Removing a login item (a LaCie power button utility)
Reinstalling Snow Leopard starting up from the Install disk.
I am now trying to figure out if there is a third party startup item such as a daemon that is causing the problem. I am planning to remove some third party daemons from the folder /System/LaunchDaemons.
Are there any suggestions as to a process to trouble shoot this? Is there a way to see at which daemon triggered the problem? Is there a log file I could look for?
Is there a reason why the problem is not consistent? Could this give me a clue as to where to look?
Any help would be appreciated, Thanks.

Yes, the admin is the first account set up on a fresh install
Make a folder for each user on the data drive
Admin
User 1
User 2
User 3
and drag and drop a copy of each of their
Documents, Movies, Music, Pictures, (Public and Sites if used)
into it if they have files.
When your ready to set up Snow keep this in mind.
Within the iTunesLibrary file there are pathnames to where the music is located.
For example
file://localhost/Users/hummermacjr/Music/iTunes/iTunes%20Music/Music/Enya/A%20day%20without%20rain/03%20only%20time.mp3
When the iTunes music is returned to each users Music folder after you upgrade to Snow you need to match the pathnames so the playlists are preserved.
So you need the same user names and same hard drive name (different passwords if you want) or else there could be location issues, not only in iTunes, but perhaps other files that locate other files and import them.
So in other words you don't want to disturb the order of things as little as possbile.

I have a MacBook 5,1 (13.3" aluminum from 2007 or 2008). Automatic updates will only let me get to OSX 10.5.8. Can I upgrade to Snow Leopard, Lion 10.6 or even 10.6.8? Also, will I have any issues with my iPhone if it's updated to iOS 7.1?

The 10.6 Snow Leopard DVD is in the Apple online store. You can get it for $19.99. You will need to be running 10.6.8 to access the App Store to order Lion or Mountain Lion. http://store.apple.com/us/product/MC573/mac-os-x-106-snow-leopard
System Requirements for 10.6:
Mac computer with an Intel processor
1GB of memory
5GB of available disk space
DVD drive for installation
Some features require a compatible internet service provider: fees may apply.
You can upgrade direct from 10.6.8 to 10.8 Mountain Lion without going through 10.7 Lion with the Late 2008 model 5,1 Aluminum Unibody. The Model 5,1 will probably run 10.9 Mavricks when it comes out.
10.8 Mountain Lion is a download from the App Store, the price is $19.99.
Mountain Lion will require at least 2gb of RAM but really needs 4gb to run smoothly.
As for third party programs see this list for compatibility with 10.8 http://roaringapps.com/apps:table
Also Mountain Lion doesn't run any Power PC programs. To see if you have any Power PC programs go to the Apple in the upper left corner and select About This Mac, then click on More Info. When System Profiler comes up select Applications under Software. Then look under Kind to see if any of your applications are listed as Power PC. Universal and Intel will run under Mountain Lion.
Before Mac switched to Intel processors in 2006 they used Power PC processors from 1994 to 2005. Power PC 601 through 604, G3, G4 and G5. Applications written for the Power PC processors need the application called Rosetta to run on Intel processors. This was part of the Operating System in 10.4 and 10.5 but was an optional install in 10.6. With 10.7 Lion Apple dropped all support for Power PC applications.

MacBook upgrade possibilities - https://discussions.apple.com/message/19577869 - "The Early 2006 model 1,1 Core Duo can only run a maximum of 10.6 Snow Leopard. The models Late 2006 Core 2 Duos 2,1 through Early 2008 4,1 can only run a maximum of 10.7 Lion. The Late 2008 model 5,1 Aluminum Unibody through the Mid 2010 White Unibody model 7,1 can run 10.8 Mountain Lion."

Restart with the Mac OS X 10.6 DVD in the drive or with the Lion USB drive connected, hold down the Option key just after the restart, tab to the installation disk, and press Enter. If the computer has a firmware password set, it needs to be provided for this to work.

I just upgraded an old Imac from Leopard to Snow Leopard, now it won't work

I just upgraded my 2003 imac from leopard to snow leopard and after restart all I get is a blue screen. Nothing happens. How can I get back to the old leopard. I use this computer for research just because of the 23'' screen. Help

I'm sure that a 2003 machine is incapable of accepting Snow Leopard. Have you checked the specs to see if it is ...
Mac OS X v10.6 Snow Leopard -Read the Technical Specifications
In particular, check the amount of RAM you have.
You could contact Apple through your National Apple store with the serial number of your machine to see if they can provide a replacement DVD ... but I doubt they can.
Contact Apple support

I have ver 10.5.8 with 4Gb of memory, can I upgrade to snow leopard?

I have a Mac Pro running version 10.5.8 with 4Gb of memory, can I upgrade to snow leopard?
My info is:
Processor 2x2.8 Ghz Intel
Memory 4GB
but when I saw the upgrade for Snow Leopard it said something about needing 5GB?
I'm not the best with tech stuff (obviously never upgraded since I got this one) and not sure if I will be able to.
Any advice most appreciated.
Need to know as I can't seem to get new itunes to download.
Thank you in advance.

Luckily prices have dropped while the quality has improved. Your system can take DDR2 FBDIMMs of 800MHz and 667MHz
2x2GB FBDIMM DDR2 667MHz @ $30

http://www.amazon.com/2008-PC2-6400-Buffered-FB-DIMM-MA970LL/dp/B007GB1I7K
Ideal is to pick up a new drive and leave your system as is and do a clean install and let Setup Assistant merge your old system files.
You may be using the original ATI 2600XT it shipped with? I would replace it with Apple's ATI 5770.
Also plan to start with a new TimeMachine backup set and leave the old one as is, you can reuse it later.
4GB is 'fine' but also is on the "I would not want to run with less" department.
What will make your Mac run faster and smoother is a small SSD boot drive, Samsung 840 128GB.

For now Snow Leopard is still supported but Apple wants to move as many users and systems as possible to 10.9 Maverick, free upgrade from Snow Leopard. But a major overhaul and doing so 10.7 and later dropped support for older applications.
You might even want to see what you use and if you need to purchase or make upgrades to apps you use now in going to 10.6.8. http://www.roaringapps.com

Hi, I am interested in upgrading to snow leopard but I've heard in some cases it messed up peoples computers. Is there any advantages in upgrading to Snow Leopard from Leopard? Thank you in advance for the advice!

Hi, I am interested in upgrading to snow leopard but I've heard in some cases it messed up peoples computers. Is there any advantages in upgrading to Snow Leopard from Leopard? Thank you in advance for the advice points will be given to multiple users. Here are my computer specs (Leopard 10.5.8.)
Model Name:    iMac
Model Identifier:    iMac7,1
Processor Name:    Intel Core 2 Duo
Processor Speed:    2 GHz
Number Of Processors:    1
Total Number Of Cores:    2
L2 Cache:    4 MB
Memory:    2 GB
Bus Speed:    800 MHz

You need not upgrade unless there is something you do that cannot be done unless you upgrade. Upgrading OS X doesn't mess up anyone's computer. Users mess up their computers.
Your model has 2 GBs of RAM which is adequate for Snow Leopard although 4 GBs would be better. Upgrading to Snow Leopard will cost $29.00. You can order from Apple's Online Store. Here's a good procedure to follow:
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).

Hi, you need 10.6.8 first...
First you need to research all the problems people are having with the higher OSX versions, & make sure you have a bootable clone of what you have just in case.
then you must get 10.6, install it & update to 10.6.8 so you have the App Store to buy & download the huge 10.8 Installer.
Snow Leopard/10.6.x Requirements...
General requirements
   * Mac computer with an Intel processor
    * 1GB of memory (I say 4GB at least, more if you can afford it)
    * 5GB of available disk space (I say 30GB at least)
    * DVD drive for installation
    * Some features require a compatible Internet service provider; fees may apply.
    * Some features require Apple’s MobileMe service; fees and terms apply.

How do I upgrade to snow leopard from leopard if I don't have the Mac App Store?

How do I upgrade to snow leopard from leopard if I don't have the Mac App Store?

It has never been on the MAS. It's never been a download anywhere (except, maybe, as a pirated version on a torrent, which, along with being "free," will probably bring along some nice malware.) It has always been a DVD, which may be possible to obtain by calling Apple and asking for Phone Sales. Should stlll only be $29.

Can i upgrade to snow leopard my system is Model Name:iMac Model Identifier:PowerMac6,1 Processor Name:PowerPC G4 (3.3) Processor Speed:1.25 GHz

can i upgrade to snow leopard

No.
Older PowerPC Macs with IBM/Motorola CPUs can only go as far as OS X Leopard 10.5.8.
Later versions of OS X, need newer Macs with Intel CPUs to run OS X versions 10.6 and higher.
To run newer versions of OS X, you would need purchase a new or newer (used or refurbished) Intel CPU Mac.

A standard installation of SL will only replace the system files, leaving all your data and preferences intact.
But! Things have been known to go wrong, so I strongly advise backing up your current system to an external HD with the Restore function in Disk Utility before starting the installation.

Upgrade Paths to Snow Leopard, Lion, Mountain Lion, or Mavericks
You can upgrade to Mountain Lion or Mavericks from Lion or directly from Snow Leopard. Mountain Lion can be downloaded from the Mac App Store for $19.99. To access the App Store you must have Snow Leopard 10.6.6 or later installed.
Upgrading to Snow Leopard
You can purchase Snow Leopard through the Apple Store: Mac OS X 10.6 Snow Leopard — Apple Store (U.S.). The price is $19.99 plus tax. You will be sent physical media by mail after placing your order.
After you install Snow Leopard you will have to download and install the Mac OS X 10.6.8 Update Combo v1.1 to update Snow Leopard to 10.6.8 and give you access to the App Store. Access to the App Store enables you to download Mountain Lion if your computer meets the requirements.
     Snow Leopard General Requirements
       1. Mac computer with an Intel processor
       2. 1GB of memory
       3. 5GB of available disk space
       4. DVD drive for installation
       5. Some features require a compatible Internet service provider;
           fees may apply.
       6. Some features require Apple’s iCloud services; fees and
           terms apply.
Upgrading to Lion
If your computer does not meet the requirements to install Mountain Lion, it may still meet the requirements to install Lion.
You can purchase Lion by contacting Customer Service: Contacting Apple for support and service — this includes international calling numbers. The cost is $19.99 (as it was before) plus tax. It's a download. You will get an email containing a redemption code that you then use at the Mac App Store to download Lion. Save a copy of that installer to your Downloads folder because the installer deletes itself at the end of the installation.
     Lion System Requirements
       1. Mac computer with an Intel Core 2 Duo, Core i3, Core i5, Core i7,
           or Xeon processor
       2. 2GB of memory
       3. OS X v10.6.6 or later (v10.6.8 recommended)
       4. 7GB of available space
       5. Some features require an Apple ID; terms apply.
Upgrading to Mountain Lion or Mavericks
To upgrade to Mountain Lion or Mavericks you must have Snow Leopard 10.6.8 or Lion installed. Purchase and download Mountain Lion or Mavericks (Free) from the App Store. Sign in using your Apple ID. Mountain Lion is $19.99 plus tax. The file is quite large, over 4 GBs, so allow some time to download. It would be preferable to use Ethernet because it is nearly four times faster than wireless.
     OS X Mountain Lion — System Requirements
       Macs that can be upgraded to OS X Mountain Lion
         1. iMac (Mid 2007 or newer) — Model Identifier 7,1 or later
         2. MacBook (Late 2008 Aluminum, or Early 2009 or newer) —
             Model Identifier 5,1 or later
         3. MacBook Pro (Mid/Late 2007 or newer) — Model Identifier 3,1 or later
         4. MacBook Air (Late 2008 or newer) — Model Identifier 2,1 or later
         5. Mac mini (Early 2009 or newer) — Model Identifier 3,1 or later
         6. Mac Pro (Early 2008 or newer) — Model Identifier 3,1 or later
         7. Xserve (Early 2009) — Model Identifier 3,1 or later
To find the model identifier open System Profiler in the Utilities folder. It's displayed in the panel on the right.
Are my applications compatible?
