Cannot install snow leopard. Keep getting"os product manager domain error-100"

Just to double check,
1: you are hold c or option/alt key booted from the 10.6 disk that came with your machine
2: you are in Disk Utility and you have selected the drive makers name and disk size on the left
3: you attempt to click Partition tab, click on the big box, select 1 partition, select option: GUID and format OS X exteneded Journaled and it reports "can't unmount disk"
4: you do have no other drives connected to the machine
If that's all true, then you need to quit Disk Utility and use Terminal and try to force unmount the disk

Once the drive is unmounted, then hopefully you should be able to format it in Disk Utility

Cannot install Snow Leopard over 10.5.8 because "can't boot from" boot disk

I closed all my apps.
I ran the installer.
I agreed the terms.
I am ask where to install Snow Leopard.
Only one disk is available - my boot disk.
It has a yellow triangle on it.
Selecting the disk tells me "Mac OS X cannot be installed on "Macintosh HD", because this disk cannot be used to start up your computer.".
Rebooting and attempting an install direct from CD yields the same results.
My machine is a six month old aluminium MacBook, and the only difference between it in the shop and today is that it has a customer-installed 500GB hard drive and ditto 4GB RAM in it.
Help.
Neil.

Hi Mike,
Sorry you're having the same problem. It's very frustrating! I'm making some noise about it because as a consequence of being in the software biz for years, I keep machines as vanilla and default as possible whilst serving my purposes as best I can - so I hopefully tread a very well worn QA path. That I am suffering problems probably means a great many more are doing the same.
Unfortunately your solution isn't a good one for me - I simply don't have 400GB of space anywhere nearby. I do have Time Machine backup to a Time Capsule so maybe a solution is to do a vanilla install and clean disk and then a restore. I don't fancy this much though.
I can't help feeling that this is a simple defect in the installer disk detection though, that it uses some custom code rather than systemwide routine to detect bootability.
Neil.

Cannot install Snow Leopard

I am trying to install Snow Leopard on daughter's MacBook which is currently running Leopard. I install the disk and get "Mac OS X 10.6 cannot be installed on this computer". There are 2G RAM available. Any suggestions?

You can't use a disk which came with another Mac model to upgrade.

Cannot install Snow Leopard on Late 2006 iMac with 10.5.8

I tried already two times to update my iMac (currently on OS X Leopard 10.5.8) to Snow Leopard. The update process runs for about 20 minutes. The iMac restarts, and then there's a message that Snow Leopard cannot be installed. One shall contact the software's manufacturer. I checked in the Installer log file and it says something like it could not u(n)mount a volume.
There are 2 external hard drives connected to the iMac via FireWire (one for TimeMachine). Do I have to disconnect them before installing? There's also a TV tuner (DVB-S) from Terratec connected via USB and EyeTV (a version compatible to Snow Leopard) is installed. I already thought that it is maybe the EyeTV software (that came with the Terratec tuner) that prevents the installer from proceeding ...
As stated, I gave it two tries:
The first time I booted the iMac from an external hard drive with 10.5.8 installed on it, ran disk utility to check, repair permissions and verify the iMac's internal disk (--> everything was fine) and then inserted the Snow Leopard DVD and launched the installer.
The second time I booted the iMac from its internal hard disk (with 10.5.8) (=the disk on which I wanted to install Snow Leopard), inserted the DVD and launched the installer.
No success in both cases.
Any suggestions, help ??
Thanks a lot in advance!
Rainer

I think it will work if you restart from the Snow Leopard installation disc. Insert disc. Restart with the C key held down to force startup from the optical drive. You have already done a +Repair Disk+, which is a smart move before doing any system installation. So when Installer comes up, just proceed with the installation targeting your internal drive.

Cannot install Snow Leopard on late 2006 MacBook

I have been trying to perform an erase and reinstall of this machine for my daughter to use. The ram had been upgraded to 2GB, and my son had it partitioned to run Windows also. There was never any problem with the machine -- I just bought him a new MacBook Pro last year.
So - I have successfully performed the "erase" part - but Snow Leopard (from retail discs - that this machine had been upgraded to) will not complete installation. I have gotten as far as "28 minutes remaining" and then it hangs up - spinning beachball - etc.. I hear the drive start up, and then stop, over and over.
I booted from the disc and ran the Disk Utility - and it shows that the hard drive is working properly.
And of course Apple says that they do not support machines over 5 years old (something to that effect).
Any help anyone can provide is greatly appreciated!
Thanks in advance,
Kim

Ok - so I am back into Disk Utility (booted from disk and selected disk utility). There are 2 hard drive icons on the left hand side ' 60.01 GB Toshiba, and then below it (indented) "Untitled".
The 60GB Toshiba is your entire boot hard drive, the "Untitled" below it is a partition on that drive if it's indented or else it's the optical drive.
What you want to do is select the "60GB toshiba" and click Erase, then Security Option > Zero All Data and click Erase, this will map off any bad sectors that old drive might have. Will take some time so wait about a hour.
(Ideally it would be good to replace it with a newer/larger one)
Install/upgrade RAM or storage drive in Mac's
Once that is complete you head to Partition: Select 1 Option: GUID and Format: OS X Extended Journaled, give the drive a name and click "Apply"
Now your drive is formatted, quit Disk Uitlity and select the drive and install OS X 10.6.
Once it's completed reboot and setup, enter your wifi/network and get online and Apple menu Software update until clear.
The machine is ready to use.

Cannot install Snow Leopard on a new HD in MacBook

I have an older white MacBook that I want to install Snow Leopard onto again. I swapped the existing harddrive back to the original one I received from Apple when the MacBook was purchased. Before putting the hd into the MacBook I made sure to partition and format with Mac Journaled.
During startup I put the Snow Leopard disc and press C to boot from disc. Slowly but eventually, the Snow Leopard process begins. My MacBook cannot seem to detect the HD that is in the machine... When I run Disk Utility, it does not populate but the DVD drive with the Snow Leopard disc is found.
Any suggestions?

What you are saying boils down to the MacBook is not recognizing the HD now installed in it. (Regardless of the formatting, Disk Utility should at least list the drive if it is communicating with the MB's hardware.)
Open the MB & make sure the HD is installed correctly, if necessary by removing it & reseating it, making sure connectors are fully mated, nothing is interfering with its fit into the space for it, etc. Close everything up & restart it, listening for any sounds that indicate the HD is spinning up. If not, it may have been damaged. You can also run the Apple Hardware Test from your original grey system disc set (see the label of the disc for instructions about how to do that if necessary) & see if it detects any hardware problems. If so, make a note of the error code & report that.

Cannot install Snow Leopard onto external drive

I'm attempting to install Snow Leopard on a second drive, an external bare drive in an Icy Dock enclosure connected to a MacPro (running 10.6.6) via serial port. Apple Disc Utility confirms that the external drive (a Seagate 325gb) has a partition map scheme GUID Partition Table. SMART Status is not supported. Connection Bus reads as SCSI but it's connected with a serial cable.
I'm able to perform the first part of the install by selecting the external drive but when I have to restart and complete the install from the original Snow Leopard disc (10.6), the external drive no longer shows up. I've tried several times and have restarted the Icy Dock external drive enclosure.
Any ideas? Thank you.

Not necessarily. Use a backup utility so that you can deselect all the data from within your Home folder as well as third-party applications in order to create a bootable disk but without some of the excess. Any of the following should be suitable:
Backup Software Recommendations
Carbon Copy Cloner
Data Backup
Deja Vu
Silver Keeper
MimMac
Retrospect
Super Flexible File Synchronizer
SuperDuper!
Synchronize Pro! X
Synk Pro
Synk Standard
Tri-Backup
Others may be found at VersionTracker or MacUpdate.

Cannot install Snow Leopard, Icon just bounces and disappears

So so complicated to Use a Mac, absolutely the opposite of user friendly after coming from a PC: everything is hidden on Macs!
So I want to install Snow Leopard (I currently run Leopard - got the computer 2nd hand)
I have a new copy of Snow Leopard in a box with the leopard on the front.
The Adobe user guide opens fine from the disc itself so the disc works.
I double click on the install Mac os x with the blue arrow pointing down at the top.
IT bounces 3 or 4 times in the bar at the bottom. Then nothing else happens
Don't understand this. It won't even tell me what's going wrong.

Cannot install snow leopard in macbook pro early 2011. disk is rejected. what do I do?

Unable to install snow leopard in macbook pro early 2011. When I put in the disk, the computer does not accept it. What can I do?

lord1908,
some Early 2011 MacBook Pros originally came with Snow Leopard installed, and some originally came with Lion installed. If yours originally came with Snow Leopard installed, then you should be able to install Snow Leopard from its model-specific grey Mac OS X Install DVD. (The white retail Snow Leopard DVD can’t be used with it; it was made for use with earlier models, which originally came with either Tiger or Leopard installed.) If yours originally came with Lion installed, then it won’t accept any Snow Leopard DVD; instead, you’d be able to use OS X Internet Recovery to download and install its original version of Lion from Apple’s servers.

Cannot Install Snow Leopard on Macbook Pro 7,1

Hello guys,
I've recently bought a USED Macbook Pro, which has installed Mac O SX Lion (10.7)
The thing is I need to install Snow Leopard and I can't do it. I have tried by simply clickin on the Installer Icon and also by booting pressing the key "Option" but when I do this the system asks me to restart my Macbook.
The DVD I'm using a Original Copy of Snow Leopard 10.6
Any ideas? Please! Help me!
my Macbook Pro:
Macbook Pro 7,1
Intel Core 2 Duo 2.4
4 GB Ram DDR3
HD 250 GB Hitachi HTS545025B9SA02

You need the SL discs that came with the coputer. The original SL DVD you have is probably too old to support the hardware on your Mac.

Cannot Install Snow Leopard 10.6 disc on Macbook Pro (will not boot disc)

Hi there,
I have a MacBook Pro 2.4 GHz Intel Core 2 Duo with 4GB of DDR2 SDRAM. It is currently running Mac osX 10.4.11.
I am trying to install a snow leopard disc 10.6 but when I click on the disc and hit install, it restarts the computer and tries to start it up with the install disc. This is where I get an apple logo with a spinning progress wheel that doesn't go away until I force the laptop to power down.
Can anyone tell me how I can resolve this issue?
Thank,
Caleb

Double check to make sure your computer meets all the qualifications for the Snow Leopard upgrade. Especially check out the "Upgrading from Mac OS X v10.4 Tiger" section in the right column - http://www.apple.com/macosx/specs.html
Your disc may be damaged. You can always take your computer and the disc back to the Apple Store. See if they can boot.

Cannot install snow leopard from disk?

Hello.
I have an original snow leopard disk.
I want to do a clean install on my imac also running sl.
So i start up holding c. The disk intially starts but then spin down with the apple logo. I left it this way for 15 minutes and nothing.
In my macbook, it loads straight up as expected.
The drive on the imac seems fine, i burnt an entire dvd with it this morning, and from the desktop the sl disk loads fine.
So what could it be?

If the original Snow Leopard disc you have is the original for another computer it will not work. The discs that come with a computer are machine specific. However if you have an upgrade Snow Leopard DVD that should work OK.
You mention needing to partitioning a Mac's HD is totally unnessary. Can you elaborate on why you need to partition it?

Cannot install mountain lion keep getting "This disk is used for Time Machine backups" when trying to install, HELP!!!

Ok i currently have Lion on my early 2011 15" MBP. When i try to install Mountain Lion to my mac HD it keeps telling me I cannot because its used for time machine backups. I have done a search and I know I have to delete the backups.backupdb folder but I cannot find it for the life of me. If anyone can help I would really appreciate, thanks!
Nik

If you double-click on your hard drive icon the Backups.backupd folder should be on the root level of your drive. Sometimes OS X gets confused and incorrectly puts a Backups.backupd folder on your hard drive. That folder should only appear on a drive used for Time Machine
If you can't find the Backups.backupd folder try using the free EasyFind with both Package Contents and Invisible Files & Folders checked. Search for "Backups.backupd" without the quotes on your hard drive (default selection), not your Time Machine drive. Right-click on the search result and choose to Reveal in Finder. Click on the link that kisuke3 provided and follow those directions
If you can't find a Backups.backupd folder anywhere try booting into Safe Mode by holding down the Shift key right after you hear the startup chime. Keep holding the Shift key down until you see the Apple Logo. The progress bar that appears indicates the progress of the file check that Safe Mode automatically does. Give it time to finish.
Reboot normally and see if the ML installer will work. If it does wait until Spotlight is finishing indexing before turning Time Machine back on.

DON'T Install Snow Leopard on early MacBook Pro with Firmware password on!!

I'm going to summarize my postings from yesterday because I don't want anyone wasting their night like I did.
Many of us who upgraded from Tiger created a Firmware password to ensure that people won't be able to wipe and re-install the HD for sale if the computer gets stolen. I also note that, like me, many have been suffering the recent won't wake from sleep issues that make it feel like the HD is dead. Sometimes it starts from sleep, mostly it's a real hassle to get it to wake up and when it does it's generally in safe sleep mode. I managed to find a "halfway" good fix for that issue by changing the sleep mode from 0 to 3 in the terminal, found a useful script by Googling the problem. Fixes 90% of my issues on that score. But I wanted to install Snow Leopard to "hopefully" fix that issue for good.
HOWEVER, if you have a MacBook Pro 2006-2007 model and the original install disc is still Tiger, WARNING TURN OFF THE FIRMWARE PASSWORD if you created one before you attempt an install. Otherwise you'll be completely stuck in black screen **** and you cannot restart from the Snow Leopard disc once you have it in, neither can you eject it because you never get that far.
The computer, after installing Snow Leopard just gets stuck on the grey screen for a while and then goes black. The computer will not boot from the Snow Leopard disc, Techtool Protege or Leopard disc and the BIGGEST PROBLEM is; you can't Zap the PRAM with firmware active to try and continue installation as some other posters have suggested. Basically, you're screwed.
To get the Snow Leopard disc out I rebooted in Windows and ejected the disc, then put in first the Leopard disc... didn't work... then rebooted, ejected and put in the original installation disc with Tiger, that did work but no firmware password reset!!!
The only solution was for me to wipe the disc, reinstall Tiger from the original install disc, which was the only one that worked. Once I could restart the computer again in Tiger, I was finally able to reboot from the Leopard disc and disable the firmware password.
Then I restarted, zapped the PRAM and using the Leopard disc, restored my machine to its former self with my Time Machine back up. Ran Techtool Pro 5 to fix permissions and rebuild volumes etc. and now have it working again.
I think I'll leave Snow Leopard for a while since I don't know whether the zapping PRAM works during install and frankly, don't have the time to go through this entire debilitating process again. If anyone does manage to get things running on the earlier MacBook Pros please let me know how it went!
Anyway, just thought I'd give people a heads up on the Firmware password thing... it's really a bugger on the older models because it wasn't originally included on the original install disc leaving you with no options!!

Sorry, just wnated to post a comment not question, wasn't sure how to mark it!
