Hello! How can I restore an iMac 10.6.5 Snow leopard to factory settings?

Hi! How can I restore a iMac 10.6.5 Snow leopard to factory settings?

You can reset the password via Single User Mode or you can completely remove the dslocal database and start over.
If you want to delete the DB and start over (no user data will be deleted), follow these steps:
1: Boot the machine into Single User Mode (Hold down Command and S keys on boot up)
2: When you get to the command prompt, mount the file system as writable with this command:
     mount -uw /
3: Deleting the old Default node...
     rm -R /var/db/dslocal/nodes/Default
4:   Copying Default node template...
     cp -R /System/Library/DirectoryServices/DefaultLocalDB/Default /var/db/dslocal/nodes/
5: Removing Shadow Hash files... (depends on history of machine)
     rm -R /var/db/shadow/hash/
6: Removing .AppleSetupDone...
     rm /var/db/.AppleSetupDone
7: Reboot the machine with the reboot command
That will present you with the setup assistance and no users on the machine. Create a new account on the machine.

How can I restore up to the current day after restoring from a disk image??

I do two types of backups... Every night I connect my MB to TM and it backs up changes made throughout the day. On Saturdays I do the same. I bring up time machine and force to backup NOW. I then turn off time machine. I then perform an image backup of the full disk and keep that full weekly image offsite.
Well I upgraded to SL, and once again many of my drivers still don't work with SL particularly a Verizon Broadband card that I was provided drivers for that have a bug. So back to Leopard I go again.
I restored the full image backup using boot from DVD & Disk utility. This worked fast and quickly restored my MBP to exactly the point where I forced the backup to time-machine. I had done some work Sunday morning, and made changes to a bunch of files. I forced a TM backup later that night to ensure to catch these changes. After the failure of the SL load, I restored as I noted from an image which is much faster.
The question is... I am now at the same point of Sat morning. How can I restore to the point where I was Saturday night just before I did a test upgrade to SL if I touched a bunch of stuff. (Some work files, some personal files). So what I really need to restore is the files backed up after my full image from Saturday AM? Any way to do this without knowing the files I updated?
CLearly TM knows what files were changed and backed them up Saturday night before I performed the upgrade??
Thanks!
Mark

The easiest, most reliable way is to do a full system restore, as of the Saturday night Time Machine backup. See #14 in the Frequently Asked Questions *User Tip* at the top of this forum.
If for some reason you don't want to do that, you can get a list of the items that were actually backed-up, via +Time Tracker+ or +Backup Loupe.+ See #8 in the FAQ Tip.

How can I recover all my MAIL emails lost after upgrading to TIGER?

Hello,
I just bought Mac OSX Tiger today and after upgrading from the previous Mac OSX and after launching Mail, I discovered that all my INBOX emails were LOST!!!
I still have the Draft emails, the Sent emails and Trash but no trace of my 1,425 ancient and precious INBOX emails!
Please help me recover them. I tried lots of ways to get them back but cannot find them. I'd like to also understand what happened.
Thank you!

HI Greta, Did you Clean Install Tiger, or Upgrade from a previous OS? as if the latter, you might find them in the ARchived files.
I upgraded to Tiger in December and it caused problems with mail but I didnt lose the messages. So I am thinking you did a clean install.
Post back with more info please

You need to contact Apple Customer Service about purchasing replacement discs for the computer. You have posted in the PPC forum, so I assume you do not have an Intel Mac, but since you haven't stated what you have we simply don't know enough to assist you.

How do I restore my iMac with no backup after it was erased through iCloud find my iMac

I removed my iMac from my device settings on my iCloud on accident. I had bought a new one for my office and moved this one to my home for my wife.
Well, I set it up for her, did the migration from her old computer to her new computer. Worked like a charm, we sold her old computer.
It's been about 6 months now. Our home computer has all of our pictures.... Time machine was not set up.
A Few days ago I was using her computer and needed a password from my notes. I went to the notes on the computer and noticed that they were not syncing because we hadn't logged this home computer into my iCloud
As soon as I logged in my icloud the screen went to a password request mode .. So I put in my password and the screen froze, then rebooted to install OS X, time machine, disk utility....
Then I got an email saying that my iMac was found and all data was erased....
Apparently, I removed the wrong computer from my devices on iCloud. Thinking I was removing her old computer we sold, I removed this one..
Is everything lost?
All I care about is my pictures and I don't know what to do...
The back up I found I tried to restore but it got complicated when it told me I had to do a list of different steps bc the backup ..
I don't want to do anything and possibly ruin a hidden back up somewhere.
Called apple they said they didn't know why it what happened and said I had to reinstall.
I tried reinstalling twice and it won't even reinstall now..
I come home late from work and had no desire to get on the phone for hours so I came here..
Help
I don't even know why it was erased

Regardless of why it happened, the fact is that you have tried repeatedly to write data to the drive. This will result in overwriting whatever data were on the drive making any sort of recovery impossible. But you can give it a try:
General File Recovery
If you stop using the drive it's possible to recover deleted files that have not been overwritten by using recovery software such as Data Rescue II, File Salvage or TechTool Pro. Each of the preceding come on bootable CDs to enable usage without risk of writing more data to the hard drive. Two free alternatives are Disk Drill and TestDisk. Look for them and demos at MacUpdate or CNET Downloads. Recovery software usually provide trial versions that enable you to determine if the software would help before actually paying for it. Beyond this or if the drive has completely failed, then you would need to send the drive to a recovery service which is very expensive.
The longer the hard drive remains in use and data are written to it, the greater the risk your deleted files will be overwritten.
Also visit The XLab FAQs and read the FAQ on Data Recovery.
Beyond this would be erasing the startup volume and reinstalling OS X:
Install or Reinstall Lion/Mountain Lion from Scratch
Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard drive.
Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Erase the hard drive:
1. Select Disk Utility from the main menu and click on the Continue button.
2. After DU loads select your startup volume (usually Macintosh HD) from the
      left side list. Click on the Erase tab in the DU main window.
3. Set the format type to Mac OS Extended (Journaled.) Optionally, click on
        the Security button and set the Zero Data option to one-pass. Click on
      the Erase button and wait until the process has completed.
4. Quit DU and return to the main menu.
Reinstall Lion/Mountain Lion: Select Reinstall Lion/Mountain Lion and click on the Install button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible
            because it is three times faster than wireless.

How can I restore my iTunes library from iPod after a HD crash?

My computer HD crashed and had to be replaced....
I've just installed iTunes and connected my iPod, I can't find a way to restore the iTunes library from the iPod.
I keep all my music on an external HD, everything that is on the iPod (~140GB) is on the external HD (and more) so I don't want to restore the library from the iPod to the HD nor recreate playlists, etc.
What can I do?
Thanks for your help

Check out the following post. It will work with your iPod video.
Be very careful when connecting an iPod full of music to an empty iTunes library.There is very real risk of permanently losing all the music.
To prevent auto sync, before you connect the iPod go to the iTunes preferences and select "devices", then select "disable automatic syncing for iPhones and iPods".
An alternative method is to connect the iPod whilst holding down the 'control+shift' keys and do not let them go until your iPod appears in iTunes.
If you see a message that your iPod is associated with a different library and asks if you want to link to a new one, make sure you press "Cancel".
If you should click on "Erase and Sync" will erase all the content currently on your iPod and it will be replaced with the content of the iTunes library you just connected to.
When you've pressed cancel your iPod should appear in the iTunes source list under "devices" and allow you to change the update setting to manage the iPod content manually, and that will let you use your iPod for the time being without the risk of accidentally erasing the contents.
Then do any of the following to transfer your music from iPod back to the computer/iTunes.
For iTunes version 7 or later, then you can transfer purchased iTunes store music from the iPod to an authorized computer by using the "file/transfer purchases from iPod" menu. Note that the maximum of 5 authorized computers applies here.
Find out how to do that here.
How to copy iTunes purchases from an iPod or iPhone to a computer.
For all other non purchased content (your own CDs etc), check out the instructions/suggestions here.
Music from iPod to computer (using option 2). This a manual method using "hidden folders" and although it works, it is a little more involved than other methods.
Much easier ways are to use one of the many 3rd party programs that copy music from the iPod to the computer.
One of the most recommended is Yamipod. This is a free program that transfers music from iPod back to the computer. However, it does not transfer playcounts/ratings etc.
Other free programs are Pod Player, SharePod and Floola and iDump and iPodRobot.
If you want to recover just the structure of playlists from the iPod (and not the actual song files themselves), there's iRepo for Windows. which I understand has this feature along with all the standard features for these programs.
iPodRip also has the feature enabling you to reconstruct playlists.
There is also CopyTrans. This does preserve ratings/playcounts etc if those are important to you but this program is not free. It also supports video transfer.
More information is contained here.

How can I restore the sound in my iPad after using my head phones in it?

I have lost sound on my iPad after taking out the earphones. Please tell me anything I can do to restore that. This is the second time it has happened. I cannot figure it out. The keys on my keyboard don't click nor the sounds on games. Thanks

Have you got notifications muted ? Only notifications (including games) get muted, so the iPod and Videos apps, and headphones, still get sound.
Depending on what you've got Settings > General > Use Side Switch To set to (mute or rotation lock), then you can mute notifications by the switch on the right hand side of the iPad, or via the taskbar : double-click the home button; slide from the left; and it's the icon far left; press home again to exit the taskbar. The function that isn't on the side switch is set via the taskbar instead : http://support.apple.com/kb/HT4085
If you haven't got notifications muted then try inserting and removing the headphones again

How can I restore my dock from a backup after doing a clean install?

I restored the dock plist file as well as the db file (which I had to delete the original first, since it was "in use") but the standard dock remains.

I haven't tried this myself, but I'm guessing that the Dock writes its settings back to disk when it quits, overwriting what's in the restored files. There are two ways you might work around this:
Restore the files, then in the shell enter
killall -9 Dock
If that doesn't work, enter
launchctl remove com.apple.Dock.agent
Restore the files, then log out and log back in.

How can I get my favorites files and folders after upgrading to a new version?

Hi.
I recently rebooted my computer back to factory condition an upgraded to the newest version of fire fox.
I lost all my favorites, bookmarks and important folders. Is there a way I can restore that information back to fire fox?

Not if you didn't backup your personal data in the Firefox program folder or were using Firefox Sync.
You should always backup your personal data before reformatting the computer.
