IMac stuck "loading wheel" once a user logs on.

My imac stuck "loading wheel" once a user logs on. The HD seems to not have any issues I checked with disk utility. I installed Macbook Pro RAM into my iMac (about 3 months ago Because I upgraded memory and I thought it was compatible); I now want to remove it however, I don't remember which of the two in there is "suppose" to be there (I'm having problems). The two , kinds are: 2Rx8 PC3 and 1Rx8PC3: which one should I remove?

Count statistics of type of user logging in

I have an adf application with security. Once the user logs in successfully, the application redirects to the welcome page.
I want to count the type of user logged in(rrole), the date and user id and record it in the database. IT should only record the
information once when the user logs in successfully before redirecting to the welcome page. The login page is an html page.
How do I accomplish this?
Veena

Right click on the database, select edit properties.In the dimensions tab you can see the required information.
Use the below Maxl command.
query database <<appname>>.<<dbname>> get dbstats dimension;

iMac, Mac OS X (10.7.3)

It just means some spammer is using your email address as the sender address for their spam. This is very easy to do - anyone can do it simply by changing the From email address in their email program. It does not mean your account was hacked or you have a virus (there are no current Mac viruses on the loose anyway, nor has there been for years).
There's nothing you can do about it. It can happen to anyone and the spammers will move on to using someone else's email address before long.

IMac stuck in new user registration video

Hello, I have an iMac Flat Panel 1Ghz I got off ebay. I don't know the admin username and password and performed the apple recommended startup in Single User using Control-s on startup. This worked fine as I now have reset this iMac to startup on the original Apple registration video. I fill in the new user registration info but it gets stuck or freezes up after I select this computer does not connect to the internet. Is there anything I can do before I buy a new hard drive? Any help is appreciated. I don't have the original system install disks and it has system Tiger 10.4 and it won't boot up from an install disk, it goes directly into the new registration video and gets stuck. Help!!

This information does not apply to accounts that have filevault. I do not believe that you can change the password to a filevault account with in these methods.
Overview on how to fix password problems
Try running repair permissions and check for file integrity in disk utility. You do this from your startup disk. Try resetting the password by using the passswd or try deleting the .applesetupdone file. If this doesn't work, you are going to have to trash the netinfo database. Once you get logged on, you will need to re-access your data.
Disk Utility
This article deals with disk recovery, it will tell you how to get to disk utility.

Change Password
Mac OS X:
Changing or resetting an account password via GUI:
Resetting a user's password
Resetting the original administrator account password
http://docs.info.apple.com/article.html?artnum=106156
You do not have a CD/DVD
Changing password from single user mode:
You can also change the administrator's password from single user mode or create a new administrator account.
You need to get into single use mode for steps one and two that are listed below.
This page will tell you how to get into single user mode.
http://support.apple.com/kb/HT1492
Basically, you hold down the command-s key then powering on your machine. The command key has a little apple symbol on the lower left. It is between the alt/option key and the space bar. On a PC keyboard, it will be the windows key, I think.
1) You can change the password on an account. ( Do you know Unix. You are in a Unix single user console. ) The setup commands you need should be listed on the screen. For Mac OS 10.4.11, the commands are:
# Type the follow two instructions to access the startup disk in read/write:
/sbin/fsck -fy
/sbin/mount -uw /
# Start up some utility processes that are needed.
sh /etc/rc
# You will probably need to press the return key once the system stops typing.
# To find out the users on the system type, use the list command. The l is a lower case L:
ls /Users
# One of these accounts will be the administrator.
# Pick one of the users which I'll call a-user-name and type it in this command:
passwd a-user-name
# and enter the new user password. You need six characters.
# You will need to enter your password twice. Your typing will not show up on the screen just
# press enter when you complete the typing.
# For cryptic information on these commands try:
man ls
man passwd
The root account isn't enabled by default. I am not sure if changing the password on root will enable it.
2) Get the Mac to set up an additional administrative account. You can then change the password on your old account.
Start with your computer power off. Hold down command-s. Power on your computer.
Type in the following:
The first two commands will depend on your release of Mac OS X. Look at what is typed out in the console to determine the exact format.
# Type the follow two instructions to access the startup disk in read/write. Press return after each command.
/sbin/fsck -fy
/sbin/mount -uw /
cd /var/db
pwd
#List all files. The l is a lower case L.
ls -a
#The move command acts as a rename command in this format.
mv -i .applesetupdone .applesetupdone.old
reboot
Once you've done that the computer reboots and it's like the first time you used the machine. Your old accounts are all safe. From there you just change all other account passwords in the account preferences!!

Once you have a new administrative account, you can change the password of your old administrative account
blue apple > System Preferences > Accounts
• You can see that it is easy to change your administrator password. You can set a firmware password that you enter before your machine will boot.
http://support.apple.com/kb/HT1352
• For the best data security, you should use FileVault. Create a good logon password. Define and use a good backup plan. I do not recommend using FileVault unless you really need the security because it is much harder to recover your data should you have a hard drive problem and you do not have your data backed up.

i switch on my mac book pro and all i get is the apple logo and below a loading wheel , but its stuck there for like an hour !!! help??

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
If the startup process stops at a blank gray screen with no Apple logo or spinning "daisy wheel," then the startup volume may be full. If you had previously seen warnings of low disk space, this is almost certainly the case. The easiest way to deal with the problem is to boot from an external drive, or else to use either of the techniques in Steps 1b and 1c to mount the internal drive and delete some files. According to Apple documentation, you need at least 9 GB of available space on the startup volume (as shown in the Finder Info window) for normal operation.
Step 3
Sometimes a boot failure can be resolved by resetting the NVRAM.
Step 4
If you use a wireless keyboard, trackpad, or mouse, replace or recharge the batteries. The battery level shown in the Bluetooth menu item may not be accurate.
Step 5
If there's a built-in optical drive, a disc may be stuck in it. Follow these instructions to eject it.
Step 6
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.
Step 7
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.
Boot in safe mode. Note: If FileVault is enabled, 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 6.
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 8
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 9
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 10
Repeat Step 9, 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 11
This step applies only to models that have a logic-board ("PRAM") battery: all Mac Pro's and some others (not current models.) Both desktop and portable Macs used to have such a battery. The logic-board battery, if there is one, is separate from the main battery of a portable. A dead logic-board battery can cause a boot failure. Typically the failure will be preceded by loss of the settings for the startup disk and system clock. See the user manual for replacement instructions. You may have to take the machine to a service provider to have the battery replaced.
Step 12
If you get this far, you're probably dealing with a hardware fault. Make a "Genius" appointment at an Apple Store, or go to another authorized service provider.

Got a iMac upon start up it has white screen with apple logo and loading wheel spinning forever under it, does anybody know how to fix this?

PLEASE HELP!!!!!! EMERGENCY Upon start up normal start up noise occurs, then after white screen with Grey Apple logo, and a spinning loading wheel under it (thee repetitive lines NOT rainbow one) ?!? then thats as far as it goes it stays on that screen forever will not boot up. Any info on how to possibly fix? I've tried several of the Start up shortcuts , it wont even start up in Safe Mode . My fiance' is crushed she is a writer and EVERYTHING SHE HAS WORKED ON is somewhere on that hard drive. Any thoughts, i'm open to any and all LOGICAL responses, thank you very much for ya'lls time ........Its just heartbreaking to see my iMac in this vegistated coma,The whole reason i bought a mac was cause I love them I have Apple EVERYTHING, so once again please help.

Try this: Switch off your iMac wait 10-15 seconds hold down the Option Key (alt) key then press the power botton but keep the option key down. This should show all the available options to boot from. I trust you have a full backup, Good luck.

MBP stuck at gray boot screen with apple logo, loading wheel, and loading bar

Today i was using my mac book pro and it was working just fine, and i shut it off and when i tried to use it later I get stuck at this screen. I have never seen this loading bar and it doesnt seem to do any thing because it only goes as far as it is in the picture then it dissapears leaving me stuck at the apple logo and the loading wheel.
Sadly i cant get my warranty information since i cant get past boot up, and the serial number in the battery area is to small to read (the letters or numbers are literaly blobs)
I have tried holding shift at boot and it does nothing and holding alt during boot only shows the hard drive icon, but when i click it im back to stage 1.

Your Mac is attempting to fix your drive and it's not succeeding, you can let it go for some time and see if it clears up.
https://support.apple.com/kb/TS3148
Do these steps.
If on 10.6 stick a clean and polished 10.6 disk into the computer and reboot holding the c key down.
If on 10.7 hold the command and r keys and boot, you'll enter Lion Recovery Partition.
Under the Utilities Menu is Disk Utility, use it to Repair Disk (note any failures!) and Repair Permissions (ignore list)
See if your computer boots, if not repeat the above steps and use Disk Utility to format a blank external drive, Partiiton Tab, Option: GUID, format OS X extended (J) and click apply.
Next quit and install 10.6/10.7 onto the external drive, when that completes, hold the option key down and you can boot from it. Retrieve your files off the internal drive to the external.
If you cant' see your internal drive in Disk Utility, it's likely failed.
Sometimes you can software like Data Rescue, installed on another Mac or a external boot drive and "read" the failed drive for any salvagable data, provided it's still working mechnically. Good thing about DataResue supposedly is you don't pay unless it's sure it can recover some of your files. I never used it as I make many backups, or bootable clones.
Mechanically failed drives data can only be recovered by platter dissection, a very expensve process.
There is several ways to read the drive, take it out and place it in a enclosure or use a IDE/SATA to USB adapter cable with another Mac or PC (with MacDrive) or use another Mac and Firewire Target Disk Mode (hold T on the sick Mac)
https://support.apple.com/kb/ht1661
If the drive works and you got your data off of it, you can erase it (use the Zero option, GUID/OS X Ext.J) and reinstall OS X, same user name as before, update, (Repair Disk from disk if on 10.6.8) install programs and return files last (and in that order exactly) your machine will be as close as possible to the way it was.
Lastly, consider making a clone, this way you can simply option boot and use that.

If the above is too much for you, please let a local Mac/Pc specialist assist you to prevent data loss.

Zap the PRAM and Reset the SMC, and see if that fixes it. BTW. detailed computer and OS info goes a long way to solving problems.

HT1455 My iMac stucked at loading screen( Spinning gear )..

My iMac stucked at loading screen( Spinning gear ), i tried everything including reboot process while pressing shift key in keyboard but it is not responding, please help me with this. thanks in advance.

You might try the following:
I would first reset the SMC:
Shut down and unplug the Mac.
Keep the Mac unplugged for at least fifteen seconds.
Plug the Mac back in and do not turn it back on for at least five seconds.
Press the power button to turn the Mac back on.
Then I would reset the PRAM by rebooting the iMac while simultaneously holding the Command-Option-P-R keys until the machine restarts a second time.
Hope this helps

Putting iMac to sleep with more than one user logged on

Hi,
Our family shares the iMca with an account for each member.
They all leave them looged on all the time and we switch between each.
I want to force th eiMac to sleep between mifnight and 6 AM to save power.
When I set this up in Energy Save settings within System preferences, it will not execute and comes back with an error saying that there are other users logged on and this may cause them to lose work.
Any idea how I can force this to over ride any objections?
Thanks
SD

It sounds like you have scheduled it to shut down instead of sleep. Ensure you have selected Sleep and not Shut Down.

Macbook is stuck with loading wheel? Please help.

i recently got a brand new macbook pro, today I decided to restart it, and when that happened. And turned back on it started loading, loaded half way and stopped them the only thing that appears is the loading wheel thst pops up and goes away and it continues to do that, I'm new to this and Have no clue what to do!

Since you have a new MBP that is under warranty, you should take advantage of the 90 day telephone support or bring it into an Apple store genius bar for service.
You can try SMC and NVRAM resets by a safe boot:

Domain user account will not authenticate once user logs out and logs back in

Greetings,
I am having difficulty resolving an issue with a Mac user on my domain. the user can log in no problem from the initial start up, however when the user logs out and trys to log back in, the domain account and the password doesn't authenticate. the only way the user can log back in is by shutting down completely.

The guys around here who know anything about that hang out on Mac OS X Server forum. Many of them support mixed Server environments in their day jobs.

Please read this whole message before doing anything.
This procedure is a test, not a solution. Don’t be disappointed when you find that nothing has changed after you complete it.
Step 1
The purpose of this step is to determine whether the problem is localized to your user account.
Enable guest logins* and log in as Guest. Don't use the Safari-only “Guest User” login created by “Find My Mac.”
While logged in as Guest, you won’t have access to any of your personal files or settings. Applications will behave as if you were running them for the first time. Don’t be alarmed by this; it’s normal. If you need any passwords or other personal data in order to complete the test, memorize, print, or write them down before you begin.
Test while logged in as Guest. Same problem?
After testing, log out of the guest account and, in your own account, disable it if you wish. Any files you created in the guest account will be deleted automatically when you log out of it.
*Note: If you’ve activated “Find My Mac” or FileVault, then you can’t enable the Guest account. The “Guest User” login created by “Find My Mac” is not the same. Create a new account in which to test, and delete it, including its home folder, after testing.
Step 2
The purpose of this step is to determine whether the problem is caused by third-party system modifications that load automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you boot, and again when you log in.
Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a Fusion Drive or a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to boot and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal boot may also be somewhat slow.
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.
Test while in safe mode. Same problem?
After testing, reboot as usual (not in safe mode) and verify that you still have the problem. Post the results of Steps 1 and 2.

IMac Stuck at Grey boot screen - How do i recover files?

I bought one of the new 21.5 " intel imacs last year and upon powering it up today it just gets stuck on the grey screen with an apple logo. It has a bar which it loads up underneath in about 2 minutes but after that the little loading wheel animation spins for as long as i leave it.
I have quite a few files which i really want to recover so i was just wondering if there was any way to do so?.
I have tried installing from the disc but it says i cannot install on my hard drive.
Is there anything i can do?

If your hard disk has crashed (and I think it has) once you get it replaced simply restore from Time Machine or the other backup scheme you have been using. If you haven't been backing up you can request your old HD back and will have to pay a data recovery service to try and salvage any files.
This may be a painful lesson on why you should be backing up, now that Time Machine is as simple as connecting an external HD to your computer there really isn't any excuse to not backup.
You can run Apple Hardware Test following the instructions here. If you get errors post back what they are and we will try to let you know what they mean. You should also plan on taking your machine into an AASP to be serviced:
http://support.apple.com/kb/ht1509
You can also try a SMC reset however I don't know if it will help:
_SMC RESET_
• Shut down the computer.
• Unplug the computer's power cord.
• Press and hold the power button for 5 seconds.
• Release the power button.
• Attach the computers power cable.
• Press the power button to turn on the computer.
