Clean Install of Snow Leopard
Be sure to make a backup first because the following procedure will erase
the drive and everything on it.
     1. Boot the computer using the Snow Leopard Installer Disc or the Disc 1 that came
         with your computer. Insert the disc into the optical drive and restart the computer.
         After the chime press and hold down the "C" key. Release the key when you see
         a small spinning gear appear below the dark gray Apple logo.
     2. After the installer loads select your language and click on the Continue
         button. When the menu bar appears select Disk Utility from the Utilities menu.
         After DU loads select the hard drive entry from the left side list (mfgr.'s ID and drive
         size.) Click on the Partition tab in the DU main window. Set the number of
         partitions to one (1) from the Partitions drop down menu, click on Options button
         and select GUID, click on OK, then set the format type to MacOS Extended
         (Journaled, if supported), then click on the Apply button.
     3. When the formatting has completed quit DU and return to the installer. Proceed
         with the OS X installation and follow the directions included with the installer.
     4. When the installation has completed your computer will Restart into the Setup
         Assistant. Be sure you configure your initial admin account with the exact same
         username and password that you used on your old drive. After you finish Setup
         Assistant will complete the installation after which you will be running a fresh
         install of OS X. You can now begin the update process by opening Software
         Update and installing all recommended updates to bring your installation current.

Downgrade from Mac OS X Lion to Snow leopard

I was using the Mac OS X Lion 10.7 since 29th Oct 2011. However, I wanted to clean install lion to my computer. Therefore, after backing up all my files to a ext. HD, I erased the hard drive through utility disc. Once I did it I was unable to re boot the computer by press holding the command + R keys. Not even press holding the option key is not helping me to boot the computer. Both this options takes me to the Internet recovery system. Therefore, I realise my recovery disc is not functioning.
The problem is once the Internet recovery runs it opens the Mac OS X utilities system and gives me the reinstall option as Mac OS X Mountain lion 10.8, which I have never purchase. When I enter my Apple ID and password it promt me to enter the correct Apple ID and password, which I used to purchase the Mac OS X Mountain Lion. Since I have not purchase it continuously the system reject to download the Mac OS X to my computer.
However, I bought my iMac with Mac OS X Snow Leopard 10.6.4 and I am having the DVD. Once I insert the DVD to the optical drive and press hold the C key it won't boot either but prompting a '?' mark on a file icon and that's it with the DVD.
I don't have a external USB or DVD for the Mac OS X Lion and I have only the purchase date with my Credit card statement.
How can I install either snow leopard or lion to my computer. Now I am having a dead iMac
Thank you all in advance for any help.

Insert the disc in the drive and reboot. After the chime hold down the Option key for a one time boot menu. If after that screen comes up you don't see the Superdrive and or Snow Leopard DVD as a boot option then the SD is bad and need to be replaced. You could then go to another Mac and create a USB install thumb drive of Snow Leopard and use that to do the reinstall.
But you do not have to repost this same question over and over again in different threads.

Downgrading from Lion 10.7.5 to Snow Leopard 10.6 w/o Time Machine

I've been trying to solve this issue for a bit, and would appreciate any fresh perspectives on the issue.
I recently purchased a 2006 Mac Pro 1.1. It has a dual 2.66Ghz Xeon processor. I'm fairly sure nothing has been customized in the machine hardware-wise, and that it is in the original configuration apple sold it with in 2006.
The machine arrived with the Lion 10.7.5 OS on it, which was incompatible with some of the software plug-ins I use for editing audio, so I decided to re-install Snow Leopard 10.6. I inserted my install DVD like I would normally, and was greeted with the error message "OSX cannot be installed on this computer, please use version 23.1.1".
I checked out the forums, and seeing that this was a common problem (with what seemed like an easy fix), proceeded to try and install anyway. I booted from the DVD by holding "C" on start-up. After booting and asking what i wanted to use as my language, the error message "Mac OSX cannot be installed on this computer" was displayed. Thinking this was another glitch, I clicked "restore from back-up, then managed to use Disk Utility to wipe my HD and zero out the contents. I reformatted my HD to Mac OS Extended Journaled, Re-partitioned it, and then reset my NV or Pram (Command+option+P+R) until i heard the start-up noise twice.
Next, I restarted the computer, booted it from the disk again, and crossed my fingers it would let me install. No luck.
I don't have a second mac pro to clone, or a Time Machine back-up from this machine (as it is brand new to me). Furthermore, it's previous owner left me with no restore disks, or usb sticks to even put Lion back on (which i don't want to do anyway, but would at least make the machine functional until i can correctly install 10.6SL).
I do have a spare 2009 imac to work with in the meantime, with Snow Leopard, though I'm assuming attempting to clone that drive would screw with the drivers and firmware in the Mac Pro. Are there any tricks to re-install my OS without using a Time Machine back-up or clone? I have the DVD, my machine just doesn't seem to want to install from it. The nearest repair shop is several hours away.
I'm at a loss for what to try next. Any ideas?

The following will only work on a Mac that is capable of being booted by a retail Snow Leopard DVD. Fortunately, you can do the following on your model should you prefer. As an alternative you could simply create a second partition on the hard drive and install a fresh copy of Snow Leopard without having to erase the drive.
Downgrade Lion/Mountain Lion to Snow Leopard
1. Boot from your Snow Leopard 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
      Utilities menu.
2. After DU loads select your hard drive (this is the entry with the
      mfgr.'s ID and size) from the left side list. Note the SMART status
      of the drive in DU's status area. If it does not say "Verified" then
      the drive is failing or has failed and will need replacing. SMART
      info will not be reported on external drives. Otherwise, click on
      the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions
      from the drop down menu to one. Set the format type to Mac OS
      Extended (Journaled.) Click on the Options button, set the
      partition scheme to GUID then click on the OK button. Click on
      the Partition button and wait until the process has completed.
4. Quit DU and return to the installer. Install Snow Leopard.
This will erase the whole drive so be sure to backup your files if you don't have a backup already. If you have performed a TM backup using Lion be aware that you cannot restore from that backup in Snow Leopard (see below.) I suggest you make a separate backup using Carbon Copy Cloner.
If you have Snow Leopard Time Machine backups, do a full system restore per #14 in Time Machine - Frequently Asked Questions. If you have subsequent backups from Lion, you can restore newer items selectively, via the "Star Wars" display, per #15 there, but be careful; some Snow Leopard apps may not work with the Lion/Mountain Lion files.

Downgrading to Mac OS X v10.6 Snow Leopard Issues

Hey there. I recently have bought a MacBook Pro with lion already on it. I wanted to play old mac games on it so I heard you could downgrade to snow leopard if you have the disk to install it. Will it work even if the lion is already installed on the computer (latest version of macbook). Also, I try to do it, since I have the disks, and it restarts my computer but doesnt start...It's just a blank grey screen that doesnt do anything. Please Help. Thanks

I repeat, you can't use any system older than the system your Mac ships with.
You can only do that if your Mac shipped with SL or earlier.

HT2311 i want to update my mac o s x to snow leopard

i want to up grade my mac o s x it is a 10.5.8
i cant seem to find it in i tunes to add to my system

To upgrade to Snow Leopard, you must purchase the install DVD from Apple.
Once you get to Snow Leopard, you will have another App Store outside of iTunes for the Mac.
Everything in iTunes is for iOS and only runs on iPhones, iPads or iPods.

How to downgrade from OSX 10.8.5 to Snow Leopard, on an Early 2011 MacBook Pro, without the original installer disk?

Hello! So here are the specs.
I have an Early 2011 MacBook Pro, which came with OSX 10.6.6 by default.
I've lost my installer disk so I though I'd buy a retail one from the online Apple Store, and version 10.6.3 is what they sent me.
Simply running the install OSX app won't work, I get a msg saying:
-- You can't use this version of the application "Install Mac OS X" with this version of OS X. You have "Install Mac OS X" 23.1.1. --
So, I've tried booting from the new disk hoping to erase my current drive and install Snow Leopard, but no can do, I get 3 beeps and have to force shutdown (not RAM related, see below). Laptop works fine when I spare it this maneuver.
After some research I understand 2 things:
1. Only the original installer disk will let me restore factory settings (and I don't have it).
2. I can only install the default OSX (10.6.6) or a later version (that 10.6.3 DVD may not have the correct drivers for my system).
Are these conclusions right? If so, would the Apple Store replace my disk for an updated 10.6.6. one? If not, then what are my options?
Thank you!

Can I upgrade my PowerBook G4 from Mac OS X Tiger to Snow Leopard?

I am running Mac OS X Tiger 10.4.11 on my PowerBook G4. Can I upgrade to v10.6 Snow Leopard? Just asking because I never upgraded to v10.5 Leopard. Are there any adverse impacts of doing this for my PowerBook G4?

Hi jjhron;
As Stedman says you can't go to Snow Leopard with your G4 PowerBook but if your PB meets the specs for Leopard you can upgrade to that instead.

Migration from Mac OS 10.3 to Snow Leopard

Hi All,
I'm trying to transfer the mail account and a few other things (keychain, favorites, bookmarks, etc.) from my dad's old emac running 10.3 to a newer macbook pro running snow leopard. Unfortunately there is not migration assistant on the emac and no way to get one, so I'm doing it by hand. I've already brought over all of his documents, pictures, and songs, BUT, I need to know how to bring over his mail. I thought I could just copy the mail folder from the old emac into user\library\mail on the new, but when I try to open mail, I get prompted to set up an account.
Any help would be appreciated. This is a christmas present for my dad.

I would look in Mail forum:
http://discussions.apple.com/forum.jspa?forumID=1338
http://www.apple.com/support/mail
And Mail files will have to be imported, the file structure has changed a lot, generally with each new version. Sometimes you have to go through an intermediary program to convert, sometimes Thunderbird.
And may need to export into a compatible format. I know over the years using email, I've had to go through that more than a couple times.

Can I downgrade mail from Lion Mail(v.5) to Snow Leopard Mail(v.4)?

I just bought a new MacBook (13.3" running Lion OS 10.7.1). I -really- don't like the new format of mail and have problems with searching and other organization methods I worked out. I would like to downgrade from Lion Mail (v.5) to Snow Leopard Mail (v.4). I understand that some people have downgraded the whole operating system and saw those instructions in the discussion forums, but I would like to -only- downgrade mail. Any ideas?
Also, any recommendations on reducing my load times and delays in mail? I have over 100,000 emails over the past 4 years that are bogging down the system. I have tried archiving some older messages, but the system freezes and then downloads all the attachments from my oldest messages, filling up the entire hard disk. Thanks in advance!

There is a long thread about this -- https://discussions.apple.com/message/15733107#15733107 -- and the bottom line is that it is possible to install and run SL on a 2011 mini (with some rather wonky hacking...) BUT it doesn't work very well. Performance benchmarks of the same machine in SL and Lion show the SL as definitely slower.
Plus people are having problems with certain features on the machine not working.
I think that your performance issues sound like something else is wrong... The 2GB is a definite problem -- do you know that you can buy 8GB for the machine for $60, and getting it installed is a snap? But the first thing that I would do is to install applejack and boot into single-user mode and run disk repair (aka fsck.) Another question -- if you look on your console, do you see a voracious cpu-eating process called mds? It's the indexer for Spotlight, and there is nothing to be done about it than to just wait it out, and your machine will work much better when it is done. And Spotlight is not just a SL problem -- if you install SL it's going to want to index your disk, too...

Hi, I want to downgrade from OSX LEOPARD to OSX TIGER but I have a few questions regarding this. My iMac is originally from Sep 2007 it came preloaded with tiger. I have original install (2) tiger discs version 10.4.10. I want to know if it is safe and what are the necessary steps to do so. Also by downgrading im wondering if a lot of apps nowadays support tiger for example I have photoshop version 5 and 4 these are very important to me. One last question does anyone know of any reliable virus protection for mac that doesnt slow down your computer? because I have read that a lot of them do so. If anyone can help me I would greatly appreciate it! Here are the specs for my iMac

Most of the time a perception of general slow performance is the result of installing third party junk alleged to speed up, "clean" or "optimize" your Mac, or to look for viruses that don't exist. Ideally you would know what you installed so you can uninstall it, but if you don't know or aren't sure there are techniques such as Safe Mode and creating a temporary user account to confirm that suspicion.
If you open Activity Monitor it may show a process, or processes, that occupy a lot of your system's time.
Slowness confined solely to web browser activity is often the result of an inexorable progress toward websites that demand ever more processor-intensive tasks. If your slow performance is strictly limited to web browsing, you might try disabling Flash by either uninstalling it, or use utilities such as ClickToFlash that allow you to control what Flash content gets loaded. Flash in itself is not inherently evil, but there is nothing to stop websites or the advertisers who pay for them from writing horrible Flash code that can do everything from hogging 100% of your CPU's time to causing random crashes. You can watch Activity Monitor as in the above to correlate these troublesome web pages with performance degradation.
You are correct; if your computer shipped with Tiger you may certainly revert to it. I forgot that Tiger was shipping on new Macs as recently as five years ago. To downgrade it would be necessary to completely erase your hard disk and boot with the Tiger installation DVD, followed by installing it anew. Such drastic measures are not necessary and you are unlikely to be satisfied with the results anyway.
Assuming your system is free of third party parasitic junk attached to OS X in an ill-conceived attempt to improve upon it, that your hard disk drive is sound and the boot volume has enough free space to work with, by far the best performance-enhancing improvement would be to add more memory. Buy as much as your computer can use and that you can afford. 2 GB is not that much any more.

Downgrading from Mac OS X 10.9 to Mac OS X 10.8 originally shipped

Hello
I purchased thiis MacBook Pro 13.3 inches online from Amazone Last June.
It was shipped with Mac OS X 10.8.
Being prompted, during 28 October 2013 I wanted to download online Mavericks but failed by corrupting my external drive containing all my backups through the time machine.
Then, on 30 October, a local Apple authorized service provider also failed to restore my data but however restored the system and installed Mavericks Developer Recovery Update after installing Mountain Lion.
Now, I want to go back i.e. downgrad from Mac OS X Mavericks to Mac OS X Mountain Lion 10.8 which was originally shipped to me. I do not know if the builtin Mac OS X is still there in the system.
I shall appreciate if anyone comes forward and help me out.
Thanks.

Try booting using Internet Recovery mode
http://support.apple.com/kb/ht4718
Backup all your data
Make sure your network has WPA security. This does not work with WEP networks
Shutdown your machine
Press the power button and hold Command-Option-R
Wait for Internet Recovery to load a list of networks (read the note at the bottom)
Select your own network
Internet will now download the Mountain Lion recovery image(assuming your mac shipped with it)
Select Disk Utilities
Select your Mac disk
Warning! This is your last chance to back out!!!!
Select the Erase tab
Select Mac OS Extended Journaled and give a name
Exit out
Select Reinstall Mac OS Mountain Lion
Follow the instructions
Viola! You have downgraded to Mountain Lion!
Notes
Sometimes, if the mac already is connected, it will skip the network selection screen
You must erase the disk in order to let the installer continue
Good luck! Tell me how it went

How do I downgrade from Mac OS X Lion 10.7.5 for my wife , me and my office

how do I downgrade from Mac OS X Lion 10.7.5 for my wife , me and my office

You cannot downgrade a machine that shipped with 10.7 installed. Such a machine can only run 10.7 or later. As for the older machines, you would need to use the old Mac OS X install disks to erase the hard drive and reinstall the system.
I don't really understand the issue regarding minimizing windows. If the difficulty is that you want to use the green "+" button in the iTunes window's title bar to resize the window rather than toggling between the full window and the simplified window with only play controls, that is not unique to Lion. That has behaved the same way for some time. Try option-clicking on the "+" button.

How to downgrad from mac OS 10.9 to 10.8?

Hi All,
I have macbook pro 15 Early 2011. I have updated my macbook pro with Mac OS 10.9(Mavericks). After fewdays my macbook become terribly slow. So i decied to downgrade from MAC OS 10.9(Mavericks) to MAC OS 10.8(Mountain Lion).
Please provide me the steps to be followed to the downgrade.
I have downloaded my copy of mountain lion and trying to install but it doesn't allow me to downgrade since my macbook has latest OS.
Please help on this.
Regards
Bhasin

Bhasin,
to downgrade from Mavericks to Mountain Lion, you’ll need to boot into Recovery mode, run Disk Utility there, and completely erase your internal disk. Since you have an Early 2011 model, it originally came either with Snow Leopard (and two grey installation DVDs in the box) or Lion (and no installation DVDs in the box) installed. If it originally came with Snow Leopard, you’ll need to reïnstall Snow Leopard from its grey Mac OS X Install DVD. If it originally came with Lion, you’ll need to perform an OS X Internet Recovery to redownload Lion from Apple’s servers and reïnstall it. Once either Snow Leopard or Lion is installed, run Software Update; once the OS has been updated, you can then upgrade to Mountain Lion.
