Created: Clean Install of OS X 10.6 Snow Leopard

I found out that I answer this question over and over again and seen other people answering it as well so thought that I would create a step-by-step guide how to do this so we don't have to type the steps over and over again. The guide is also more specific than most posts are

Link: Clean Install of OS X 10.6 Snow Leopard

Feedback is very welcome. I tried to make it as simple as I could

I'd suggest that you add some screenshots at every step, at least it'll be easier to follow and gives people reassurance that they're on the right track.

The issue with pictures is that you can't take screenshots while installing AFAIK. Sure I could use a camera but that might start to be tricky. Besides, Lion will be out soon and it would require a new guide

Thank you

I've just bought a new iMac and am giving my 13 yr old son my 3 year old iMac, so he can at last move onto a Mac. Benefits are multiple for him and for me, but firstly I'll no longer have to provide 'tech support' to a machine I no longer really understand, and which is always a very frustrating experience.

I also won't have to listen to his PC fan whining through the house - sounding like a hairdryer! it's a Dell, and it's been truly disappointing!

Anyway, I wanted to do a clean install on my old iMac - and found this perfect guide. So, thanks very much Hellhammer, a great guide, spot on, and I appreciate very much the time you took to produce it.

Peter

Hellhammer, just wanted to say thanks for creating the guide! It was very clear and easy for me to follow when I recently upgraded to Snow Leopard.

I just did clean installs on two 2011 MBPs. I'll mention what i did when I transferred my information , because for once everything turned out well. The data was on a HD removed from a dead MBP that was running 10.5.

I upgraded the old HD in firewire enclosure to 10.6 and ran all updates on it. I then ran the app CleanApp to remove programs from the old drive I didn't want any more. Migration agent was used transfer the applications. It appears 3rd party apps have the registration code transferred, but Pages asked for a reg. no.

With iTunes, i deleted the iTunes folder in Music on the new HD and then copied over the old iTunes folder. This worked and preserved all metadata.

edit- i should mention that Migration agent made a mess of transferring itunes. This could have been because i had my music files away from where itunes would normally find it. Before swapping itunes folders, I moved and renamed a few files so that both itunes folders matched.

Not "clean install"

The term "clean install" refers to OS 9 and before. It was a clean installation, a new "System Folder", not a wipe. A wipe is a "clean erase". The equivalent of "clean install" in OS 10.5.8 and before is the option "Archive and Install". The archive is the old system, the install is the new system. The two (old and new) are totally separated, thus the new install is clean, a clean install. With OS 10.6, a direct reinstall will automatically put the old system into an archive.

The big glitch with the 10.6 reinstall is that it fails to handle an archive of the Users. Instead, it changes the status of all previous user accounts to standard accounts and upon restart, the Setup Assistant directs you through creating a fresh account -- that may or may not be an admin account.

The surest way to get a proper clean install (as opposed to clean erase) out of OS 10.6 is to complete the reinstall, complete the new user, boot to single user mode, rm the local.nidb, mv the old "Users" directory to "Users-old", rm the .applesetupdone file, reboot, create a real admin account (best to use the same full name and shortname as your original account), and Bob's your uncle. Then you can create new admin users to match any other old users you may have had. Mucking about to move stuff from the old to new users should not cause any permissions miss-match if they have the same short names.

The purpose of a clean install in OS 9 and before was to solve OS install issues, not to solve HDD file system errors. Archive and Install also has the purpose of solving OS install issues.

Anyone who was using computers when Apple introduced this feature (System 7.5) knew that it was hidden then and you had to hold Command-Shift-K to get the options window to appear. Starting with OS 7.6, the installer showed an "Options" button to bring up that pop-up screen with a check box for "Create New System Folder (Clean Installation)".

I have no idea why the PC geeks usurped this phrase and decided it required a format. Format is to remove a corrupt file system, not needed to clean install a fresh OS. Anyone who erases a HDD when there are no errors found by Disk Utility, Drive Genius, TechTool Pro, Disk Warrior and the like must have a phobia. Just go really overboard and replace the whole HDD. Probably has problems that even an erase missed. Toss it.

Hi, can you please tell me what is going on with my situation?
a. First I tried to perform clean install by loading the Mac OS X 10.6 disc directly to the drive, then it failed on auto boot from DVD
b. I followed some online instruction on copying the whole installation disc to an externel HDD and use the HDD as installation disc by setting it as startup disc. Then the following message appear:
- This version of Mac OS X is not intended for your hardware (something like that)
c. After that the HDD no longer bootable.
d. Then I tried to boot from Disc again by pressing Option Button and two bootable options appear, the internal HDD and the DVD for Mac OS X 10.6. I chose the DVD and it booted from the disc. In the middle of the way a block sign appear and the disc did not seem to be spinning (reading) anymore.

This is my mac specs:
Model Name: MacBook Pro 15"
Model Identifier: MacBookPro1,1
Processor Name: Intel Core Duo
Processor Speed: 2 GHz
Number Of Processors: 1
Total Number Of Cores: 2
L2 Cache (per processor): 2 MB
Memory: 2 GB
Bus Speed: 667 MHz
Boot ROM Version: MBP11.0055.B08
SMC Version: 1.2f10

some said that I need to do gradual upgrade from 10.4.11 to 10.5 first. Is that true? Or can I just do clean install like what you wrote?

Is the disc you have the retail version of Snow Leopard? If it's from another computer, then it may not work.

The guides are temporarily down since the security leak earlier this week.
Presumably, they'll soon get back.
