How to Perform an Archive and Install
1. Be sure to use Disk Utility first to repair the disk before performing the Archive and Install.
Repairing the Hard Drive and Permissions
Boot from your OS X 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 Installer menu (Utilities menu for Tiger.) 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, then quit DU and return to the installer.
If DU reports errors it cannot fix, then you will need Disk Warrior (4.1 for Leopard) and/or TechTool Pro (4.6.1 for Leopard) 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.
2. Do not proceed with an Archive and Install if DU reports errors it cannot fix. In that case use Disk Warrior and/or TechTool Pro to repair the hard drive. If neither can repair the drive, then you will have to erase the drive and reinstall from scratch.
3. Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When you reach the screen to select a destination drive click once on the destination drive then click on the Option button. Select the Archive and Install option. You have an option to preserve users and network preferences. Only select this option if you are sure you have no corrupted files in your user accounts. Otherwise leave this option unchecked. Click on the OK button and continue with the OS X Installation.
4. Upon completion of the Archive and Install you will have a Previous System Folder in the root directory. You should retain the PSF until you are sure you do not need to manually transfer any items from the PSF to your newly installed system.
5. After moving any items you want to keep from the PSF you should delete it. You can back it up if you prefer, but you must delete it from the hard drive.
6. You can now download a Combo Updater directly from Apple's download site to update your new system to the desired version as well as install any security or other updates. You can also do this using Software Update.
Thanks for your reply. By doing this, will this hurt/affect my computer in any way? Also, will I lose any data? The only reason why I want to switch back is because I want to undo my encounter with these wireless problems of not having a stable connection. If there is any other (and safer) alternative besides "reverting" back to an older OS X, please share! It seems that many people have had these problems even before 10.5.3 update. Has anyone else's wireless been affected after they downloaded the latest OS X release besides me? What have you done about it? I'm not sure if I should call my wireless company or if I should take my MacBook to the apple store and have a "genius" look at it. I don't have any other means of getting on the internet so timing is very crucial here, and I don't think I can wait until Apple comes out with an update. Thanks everyone.
Any time you attempt an Archive and Install or other system upgrade there is a danger of data loss. You should always have backups of your data for protection as well as maintain a bootable backup of the current system in the event that an installation results in data loss.
If you read the article on Archive and Install you would know that it does not erase the hard drive. An Archive and Install is the only option for replacing or downgrading an OS X installation without erasing the hard drive.
Frankly, I have no idea what your wireless problems may be or what may cause them, but there is no assurance it is caused by the version of the operating system version.
