Snow Leopard will not install on 2008 Intel iMac

Trying to install a purchsed copy of Snow Leopard onto an Intel iMac (2008 model). System previously on system was 10.4.11. Started the first Upgrade attempt and the upgrade stopped at 33 minutes remaining - would not progress any further.
Force power down and tried again selecting Upgrade. This time it got to 16 minutes and never went further.
Next attempt I reformatted the drive, ran Disk Utility to Repair Disk (no problems detected). The ran a full install. Stops at 16 minutes.
Tried again - Partitioned drive, erased drive, tested drive, ran installer - 15 minutes - no further.
No error messages - nothing - it just sits there.
Reset PRAM, reset SMU - same thing after another attempt.
This system was running fine under 10.4.11. We just wanted to upgrade it to 10.6 for application compatibility requirements (10.5 or higher required to run latest version of application).
Any ideas would be greatly appreciated.

Next I'd run the AHT (Intel-based Macs: Using Apple Hardware Test) - if that picks up any hardware issue then you don't need to waste any more time troubleshooting. (Run the long test in the AHT, maybe loop it overnight if you're not in a hurry)
After that I'd boot the machine in target disk mode (How to use and troubleshoot FireWire target disk mode) and boot the other machine to the install disk - you should then be able to install to the first iMacs HD, it'll show up with a firewire symbol when you "select you destination".
If still having trouble, then I'd go into disk utilty, erase tab, options and select the "zero out data"" option. Then click the erase button. This will write to every byte on the HD, so an additional test of the integrity.

Snow Leopard will not install if you do not have 1GB RAM or more

I ran into one problem when I tried to install snow leopard, The problem was I throught my Macbook had 1 GB of RAM in it, then after I my first try on install then it mentioned I did not have 1 GB of RAM, so I checked it and I only have 512 MB, so that is low and I have a 1st Generation Macbook, So now I ordered a 2 GB of RAM for my MacBook I'm waiting for the memory to arrive so I can install it into my Macbook, then I will install snow leopard.
Snow Leopard will not install if you do not have 1GB RAM or more, but if you have 1GB or more in your Macs then you will be fine

The system requirements for the OS have been public knowledge on every major tech blog, apple fan blog, apple rumor site and Apple's site for at least 4+ months. So it's not like they just decided at the 11th hour that you needed 512MB of RAM. Not to mention, just about every piece of software I've ever purchased has the system requirements printed in a very tiny print in a very un-obvious place on the packaging. So that's nothing new... for Apple and the rest of the software manufacturing world.
As the consumer, it's your responsibility to do the appropriate research (either online, over the phone or asking the sales rep) what requirements are necessary.

Snow Leopard will not install on Macbook Air--have spent days on this!

Hi, all!
I have tried almost 10 times to install the Snow Leopard upgrade to my MacBook Air via the remote disk and it has either frozen, quit, or disconnected each time (freezing is the most common occurrence). It takes 5 or more hours to get to that point. The computer with the disk in it is a MacBook (Intel), and both computers have plenty of space available and are running on the same secure wireless network, so there shouldn't be a problem. (I have installed applications between these two computers before.)
This is incredibly frustrating, so any advice would be much appreciated.
Thanks!
Lisa

It's highly likely that your wireless network is the problem. Normally I'd recommend grabbing a couple pieces of CAT5 and hooking both machines up via wired network temporarily but that's not an option with the Air.
You could try at least connecting the MacBook via wire, eliminating at least half the wireless contention (turn off the wireless on it to be sure you're using the wire). Since you've already tried 10 times, an 11th probably isn't out of the question.

Snow Leopard will not install on my iMac

When attempting to install Snow Leopard on my iMac, the install says that there is no bootable disk. We have the drive partitioned - front drive has OS, back drive is exclusively storage. It says neither drive is bootable, yet we do indeed boot.

Is your iMac an Intel-based? Are you upgrading from Tiger or Leopard? I suspect the issue lies with your drive not being properly formatted with the GUID partition table which is native to Leopard and Snow Leopard. Generally, you can find more information here: http://support.apple.com/kb/TS1600

Snow Leopard will not install MacBook 1.83 GHz

Hi,
I have a retail Snow Leopard 10.6.6 installation DVD and I'm trying to install it on a MacBook 1.83 GHz Intel Core Duo:
http://support.apple.com/kb/SP31
The MacBook has 2GB of RAM installed and a HD of 320 GB.
The Snow Leopard installation loads but it states that Mac OS X cannot be installed in the computer.
However, it seems that this machine has all the requirements of Snow Leopard. Any thoughts?
Thanks

Oh, I see. Indeed, what I meant by "retail DVD" was that I have a 10.6.6 that came with my MacBook Pro. I will try to get a Snow Leopard Install DVD 10.6 to see if it solves the issue.
Thank you very much!

Snow leopard will not install

I have an old mac Book with OS X 10.5.8 running on it and I have a family DVD version of leopard that I have installed on my imac( that currently runs Lion(10.7.2) so it should install in my mac book. When I insert it into the macbook it whizzes for a bit and then spits out the dvd. I need to update this mac book so that I can run icloud etc on this machine to keep up with all my appointments etc ( I did check that it has an intel processor as required for lion)
Any ideas?

Sounds like the drive is having problems. Try:
Intel-based Macs: Resetting the System Management Controller (SMC) - http://support.apple.com/kb/ht3964
Apple Portables: Resetting the System Management Controller (SMC) - http://support.apple.com/kb/HT1411
If that doesn't do it you can try a drive cleaning disc. If that doesn't do it you're looking at new hardware.

My early Intel iMac running Snow Leopard will not boot past the apple logo. I have tried holding the c key and inserting the install disk, but nothing. What do I try next?

I have tried resetting PRAM and all other items listed in the Apple support site. This happened after an update to iTunes was added. Also this is happening to other people. Please help.

Install Disk for Snow Leopard will not boot on an iMac 27in

My Install Disk for Snow Leopard will not boot on my iMac 27in. The Apple Logo is the only thing the user will see. The current OS on the system is 10.6.6. Upon placing the Snow Leopard DVD in the system, the DVD players spins for a few seconds and displays the Apple Logo. Nothing happens after 20 minutes.

Yes, it is ridiculous how it is impossible to install Snow Leopard. I have two Snow Leopard DVDs: one that I purchased for a Macbook soon after it's release (10.6.0), and one that came with my iMac (10.6.4). Both of these boot up my Macbook (running 10.6.7) just fine. My SL 10.6.0 DVD mounts onto my iMac (Lion 10.7.0), but you cannot run the install. I attempted to boot from this DVD and got the infinite white screen and Apple logo, as some have reported above. The other SL 10.6.4 DVD will not even mount in Lion, and will not even show up as a bootable drive when I attempt to select it after holding alt/option on reboot.
I created a bootable external drive from SL 10.6.0, attempted boot, same infinite white screen/apple logo.
I created a bootable external drive from SL 10.6.4 on my macbook. I attempted to boot from this drive, and got the white screen of death, except that this time I actually got the loading symbol underneath the Apple logo. After about a minute of attempting to boot, the Apple logo changed to a circle with a diagonal line through it (the "NO!" sign).
I took my iMac to the genius bar. They inserted SL 10.6.0, which would not boot. Then they determined that my computer had to run 10.6.4 and later. So, they restored an image of SL 10.6.4 onto my partition (not an install from an image, but an image of SL already installed). Hurray! Snow Leopard was successfully shoved onto my iMac!
I then deleted a third partition on my hard drive I did not need anymore, which somehow screwed up my SL partition (even though it said "Will not erase partition SL or Macintosh HD). Now I am back at square one, and I guess I need to take my flippin iMac back to Apple for them to do what I should be able to do.
I like Apple, but sheesh do I hate Lion right now.

If I upgrade from Mac OS v 10.5.8 to 10.6 Snow leopard will my installed applications such as timemachine and MS Offfice for Mac 2008 still work?

If I upgrade from Mac OS v 10.5.8 to 10.6 Snow leopard will my installed applications such as MS Office for Mac 2008 still work? Will time machine files created under OS 10.5 still be accessible?

Yes

Leopard will not install on my Power G5

I recently purchased Leopard and cannot install it on my Power Mac G5.
It says that a Intel chip is required to install it.
I take it that means my mobo, but why would Apple not make their computers compatiable?
Help me out please.

It sounds like you purchased Snow Leopard and not Leopard. It is Snow Leopard which requires the Intel processor and not Leopard.

Snow leopard will not load on MM 3,1

Trying to get (X.6) Snow Leopard to load on my son's Mini 3,1
but it keeps saying Snow leopard can not be installed.
Trying to upgrade from 10.5.8
Documentation says X.6 should load on any intel computer, and the mini is a core duo.
Any suggestion are appreciated.
AJ

Thanks for responding Sven.
Actually, it is from my other sons newer 2.4 ghz mac mini.
You would think it would work being another mac mini.
Looks like I might have to purchase the retail. Sheeezzz
I miss the everything goes old days. : )
Thanks for your help,

Snow Leopard will not load or install

I need lots of help.
Bought the Snow Leopard Box Set.
Load the DVD only to have it eject after it spins 3 times.
Cleaned the optical drive, tried other cds and dvds - they work.
Even loaded the iWork DVD from the box set - that loaded but wouldn't install.
Was told to download the Combo Update from Apple. Have the .dmg file sitting on the desktop but that won't install.
Repaired permissions.
Tried it all again, same result.
Don't have the original start up discs - anyway to erase the HD with out them and then do a clean install?
Any and all advice would be appreciated.
Thanks,
Mark

Were you having any issues with your computer before you decided to purchase Snow Leopard? It is my observation on these forums that people are sometimes motivated to buy SL because they are having issues with their current setup.
You say you downloaded the Combo Update but it won't install. Exactly what Combo Update are you talking about? Surely you are not talking about the Snow Leopard Combo Updater, right?
It is certainly possible your problem is simply you have a bad SL install disc. You wouldn't be the first. Where did you buy the SL Box Set? Does Montana even have an Apple Store?

Macbook upgrade to Snow Leopard will not complete install stuck with reboot screen, turned on off numerous times same scree

I have a Macbook with the Leopard OS, up to date. I decided to install Snow Leopard. Everything went smoothly until the window came up requesting me to restart the laptop after the install. I have done this numerous times same window keeps coming up after restart. I would appreciate any help.
Thanks,
R A

Thank you Watts 300. I unfortunately cannot get the Mac to reboot. I have taken the SL disk out and reinserted a number of times, however the screen remains with the restart message. Crazy.I can power it off but the same restart message keeps appearing.
