Mac OS 10.5 /
I deleted the " Private" folder ... and emptied the trash. So the folder and its contents no longer exists on my computer at all !!!
I do have the OS 10.5 dvd that i purchased years ago...
But my computer will not start from it on its own.
My question is what is the open source or terminal language code used to tell my mac to look in the DVD rom drive for startup info? I know that im not the only person in this world who has deleted the "PRIVATE" folder and emptied the trash so it no longer exists on their machine...
That said theres gotta be a common fix for a Power PC G4 that has the OS X dvd in the rom drive but wont look to it to reinstall the vital contents of the PRIVATE folder.
Once again there is not a copy of this file or its contents in the recycle bin...
Also rebooting the machine , pressing and holding the letter C does not prompt the machine to look to the dvd rom drive.
I was reinstalling pro tools and figured I would make some room by cleaning my computers HD...
Lol It was a bad choice to delete this file ...
Thanks guys

Okay sorry it took forever to respond... But for a while there I gave up on this computer!!!!
Money's been tight lately , so taking it in to a professional was not yet an option... though I did consider it eventhough.
Anyway long story short im glad I didnt spend any money because I already had all the tools necessary to fix this issue but was going about it in the wrong way. Okay so here is my scenario and the breakdown... Though this may not fix the issue for everyone :( which *****... But I know we all will have different circumstances.
Anyway here we go...
Okay so first things first.... Years ago I purchased the OS 10.5.1 disk ... So that has always been in my possession!!!!
I realize that some may not have a disk to reflash your OS to your hard drive... but if you do your in luck.
2ndly ... I had an external harddrive with all of my itunes downloaded music so it was more than okay with me to delete my primary HD because all the important stuff could either be copied over or repathed to be located.
-------If you dont want to read through the whole story the fix is summed up in the bottom section-------
Okay so now the SOLUTION!!!!
By trial and error , and pure boredom I opened up my computer to clean the inside...
AND
"Disconnected the primary HD"
and just because ....... REBOOTED my computer. Just to see what it would do.
Upon restart and though it looked like it would repeat its usual cycle...
About 1 minute in to that process my computer froze for about 2 seconds and flashed to the OS installation screen.
Mind you I havent seen this screen yet... Probably hasnt been since I installed the OS years ago.
After a bit of trial and error...
I decided to tell my computer to startup from the OS 10.5 disk located in my dvd rom drive and restarted once again...
this setting is under
Utilities / startup disk
After a little more trial and error ... I realized that I could reconnect the primary HD , restart the machine and return to the OS installation menu.
So upon this discovery
I went to the Disk Utility located under Utilities
Highlighted my primary HD located in the left hand column
Once highlighted ...
In the heading section on the right I selected the option
Erase
in which I erased My current OS on my primary HD ...
I used the first option in the list under security... Because it seemed like the least invasive and would take the least amount of time to see if this process would actually work.
I FORGOT to add something...
Another reason why I deleted my primary HD!!!!!
I forgot to say that it WOULD NOT!!!!! Show up in the STARTUP list as an option...Even After multiple reboots....
But like clockwork... Once I deleted its name IT SHOWED UP as an option!!!!
So back to the next step...
I returned to the STARTUP option under utilities ... And was then able to see MY primary HD now as a startup option...
But ofcourse it had no name because it we previously erased it.
So when Clicking my newly erased HD ... I was almost immediately prompted to REINSTALL the OS ...
Which said it would take about 57 minutes ... But I believe was alot less...
My issue was resolved ... My computer then stated the install was SUCCESSFUL!!!!!!! :))))))))))) lol ;)
It was like I was setting up for the first time ;) asking for my registration info...
The dilemma of deleting the private folder and emptying the trash is finally over resolved. Done ... and no extra money spent!!!!!!!!!
Its really crazy that the information for such a simple thing is not readily available. Especially being such a simple fix.
I know im not the only person who's had this issue , because i've seen numerous posts with similar wording.
I also know I wont be the last person to have this issue... So I hope this synopsis makes sense.
-------One more time the fix------
*Insert your OS dvd into your dvd rom drive.
*Unplug your primary HD or corrupted startup disk
*Reboot your machine...
Upon restart your primary HD will not be recognized...
* you will then be prompted to select your language.
Once selected
*Click Utilities/startup... Highlight the the selection that refers to the OS dvd located in the dvd rom drive.
* Click restart...
!!!!!!!!!!Be sure to reconnect your Primary HD Before your computer restarts and you hear the chime!!!!!!!!
If you do not replug your HD before the chime it will not be recognized.
In that case restart again.
Upon restart once again
*Choose your language...
*Click Utilities / disk utility
In the left column select and
*Highlight your HD ...
Then towards the top portion / center of the page
*Click the heading Erase
Then on the page toward the bottom
*Click security options
This will then provide erase options.
I USED THE FIRST OPTION
"Dont erase data"...
*click OK
* click erase...
Once erased which should take a few seconds
*Cancel the disk utility...
* Click Utilities / startup
And your newly erased HD should now appear in the list.
* Select your drive from the list by highlighting
It should no longer have a name.
*Once selected, you will then be prompted to restart and install the OS to your newly erased HD...
Thats it!!!!
Once everything reinstalls re-add your personal info or registration info and you are up and running.
Goodluck ;)

My computer will not start. Just the wheel spinning

My computer will not start. I get the apple with a spinning wheel.
What is happening?

Take each of these steps that you haven't already tried. Stop when the problem is resolved.
Step 1
The first step in dealing with a boot failure is to secure your data. If you want to preserve the contents of the startup drive, and you don't already have at least one current backup, you must try to back up now, before you do anything else. It may or may not be possible. If you don't care about the data that has changed since your last backup, you can skip this step.
There are several ways to back up a Mac that is unable to boot. You need an external hard drive to hold the backup data.
a. Boot into the Recovery partition, or from a local Time Machine backup volume (option key at startup.) When the OS X Utilities screen appears, launch Disk Utility and follow the instructions in this support article, under “Instructions for backing up to an external hard disk via Disk Utility.”
b. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, boot the non-working Mac in target disk mode. Use the working Mac to copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
c. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.
Step 2
Press and hold the power button until the power shuts off. Disconnect all wired peripherals except those needed to boot, and remove all aftermarket expansion cards. Use a different keyboard and/or mouse, if those devices are wired. If you can boot now, one of the devices you disconnected, or a combination of them, is causing the problem. Finding out which one is a process of elimination.
If you've booted from an external storage device, make sure that your internal boot volume is selected in the Startup Disk pane of System Preferences.
Step 3
Boot in safe mode. Note: If FileVault is enabled on some models, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Post for further instructions.
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
When you boot in safe mode, it's normal to see a dark gray progress bar on a light gray background. If the progress bar gets stuck for more than a few minutes, or if the system shuts down automatically while the progress bar is displayed, your boot volume is corrupt and the drive is probably malfunctioning. In that case, go to Step 5.
If you can boot and log in now, empty the Trash, and then open the Finder Info window on your boot volume ("Macintosh HD," unless you gave it a different name.) Check that you have at least 9 GB of available space, as shown in the window. If you don't, copy as many files as necessary to another volume (not another folder on the same volume) and delete the originals. Deletion isn't complete until you empty the Trash again. Do this until the available space is more than 9 GB. Then reboot as usual (i.e., not in safe mode.)
If the boot process hangs again, the problem is likely caused by a third-party system modification that you installed. Post for further instructions.
Step 4
Sometimes a boot failure can be resolved by resetting the NVRAM.
Step 5
Launch Disk Utility in Recovery mode (see Step 1.) Select your startup volume, then run Repair Disk. If any problems are found, repeat until clear. If Disk Utility reports that the volume can't be repaired, the drive has malfunctioned and should be replaced. You might choose to tolerate one such malfunction in the life of the drive. In that case, erase the volume and restore from a backup. If the same thing ever happens again, replace the drive immediately.
This is one of the rare situations in which you should also run Repair Permissions, ignoring the false warnings it may produce. Look for the line "Permissions repair complete" at the end of the output. Then reboot as usual.
Step 6
Reinstall the OS. If your Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
Step 7
Repeat Step 6, but this time erase the boot volume in Disk Utility before installing. The system should automatically reboot into the Setup Assistant. Follow the prompts to transfer your data from a Time Machine or other backup.
Step 8
This step applies only to older Macs (not current models) that have a logic-board ("PRAM") battery. Both desktop and portable Macs used to have such a battery. The logic-board battery is separate from the main battery of a portable. A dead logic-board battery can cause a gray screen at boot. Typically the boot failure will be preceded by loss of the startup disk and system clock settings. See the user manual for replacement instructions. You may have to take the machine to a service provider to have the battery replaced.
Step 9
If you get this far, you're probably dealing with a hardware fault. Make a "Genius" appointment at an Apple Store to have the machine tested. If you can't get to an Apple Store, go to another authorized service provider.

Hi,
Do you know which test your notebook failed? If you don't know, try the following.
Shutdown the notebook. Tap away at f10 as you start the notebook to enter the bios menu. Under the Advanced or Diagnostic tab you should find the facility to run tests on both the Hard Drive and Memory. Post back with the details of any error messages.

TS3274 My ipad display will not function, the screen will not display anything when turned on, you can see that the screen lights up but it is completely black

The screen on my iPad will not display, the screen lightens up when powered on but the screen stays black, any fix for this that I can do at home?

Try this - Reset the iPad by holding down on the Sleep and Home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons. (This is equivalent to rebooting your computer.) No data/files will be erased. http://support.apple.com/kb/ht1430

Install or Reinstall OS X 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 OS X: Select Reinstall OS X 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.

Hi The Lad,
If you have "INSUFFICIENT" disk space, then you can try and change the install location while performing the installation of the desired product. I am not sure when the error message would pop up saying that the disk space is "INEFFICIENT". Could you please share a screen shot of the error message along with the system information.

I recently bought a new laptop because my old one crashed. The only backup I had for my music was on my ipod. My new computer will not recognize the ipods music and I can't transfer anything. What do I do???

I recently bought a new laptop because my old one crashed. The only backup I had for my music was on my ipod. My new computer will not recognize the ipods music and I can't transfer anything. It keeps asking me to sync the ipod to this computer, but I'm scared to lose all my music. I want to transfer some of the music onto my iphone but I can't. I'm very frustrated and wish I knew more about computers at the moment!?!? What do I do???

You will need the help of some sort of 3rd party software to help you copy the content from your Shuffle back to your PC. Once you have done that, you can reimport this music into iTunes and configure it to sync to your new Shuffle.

I set up a passcode that will not unlock the screen. How do I reset the passCode?

If the passcode will not unlock the screen you are entering the wrong passcode. To change or remove the passcode you can use the settings app.
Settings > General > Passcode Lock
The caveat here is that to make changes to the passcode lock you need to enter the correct passcode lock.
If you do not know your passcode you'll have to restore your iPad by connecting it to iTunes on your computer.

My computer will not start the screen is white.
