Login loops on Macbook Pro

Hi ,
I m having a new issue with my Macbook Pro - at ten minute intervals, the machine re-enters the login screen and prompts me to login again.
I have OS X version 10.8.2 The only recent events of note are ..yesterday, I removed Onyx - the Mac cleaner by right clicking and selecting move to trash (on the advice of internet forums). Onyx no longr worked with this version of OS, I believe.
The other event was my 12 yr old recently hacked into the Macbook without my knowedge and re-badged the Macbook as Jonny's Macbook Pro, instead of Daddys Macbook pro. This latter incident, which resulted in a firm ticking off, is freaking me out as my son said he accessed KeyChain which he tells me is a repository for system passwords. Tell me please that's not the source of this issue. Im also concerned of cyber attacks and whether some cyber criminal has accessed my system.
I have Time Machine running well and have a month's worth of full backup so could effect a restore if needed.
Thanks in advance.

That was an old profile. This is on a new MacBook Pro that had Leopard, and upgraded to Snow Leopard. It was running for a few days fine with Snow Leopard, then one day, it went to sleep, and wouldn't wake up. Upon restart, this resulted (constant loop).
I was able to have the computer start up by removing ALL of the com.apple.xxx.plist files in ~/Library/Preferences, but now, the entire computer is SLUGGISH, as in, not usable sluggish. It is fine when starting up from external hard drive. I think I'll just backup my user folder and erase and reinstall.

Login loop on MacBook Pro

Right after I login, my wallpaper loads, and I see my dock for a few seconds, then, it goes back to the login window. This repeats over and over again. Never giving me access to anything on the computer.
I had looked up a similar problem for prior OS's, related to launchservices plist, but I can't seem to find the same file in 10.6?

I can no longer login to my Macbook Pro.

Hello everybody,
I am the owner of a Macbook Pro (bought it in 2010) with the newest Maverick software. There was an new update to be done (I don't really know which one), which went without problems. Afterwards I wanted to open mail, but I got a notification that the program needed to import all my mails and data from the program to this new version. I pressed the 'OK-button', but my laptop was not able to perform this task: I got a notification that there was not enough storage room for this action. I thought this was rather odd, becaus I had never had any problems like that. So I decided to restart my computer, hoping that I would work again afterwards.
Unfortunately, now I am no longer able to login to my Macbook Pro! Even the guest user-account doesn't work. Once I type the password (which I know for certain is correct), a white screen appears, then a quick lightblue screen, then again the white screen with a grey loading-sign and then It goes straight back to the login page...
I have already tried this a dozen times as well as logging in with the Safe boot, but that doesn't work either.
Can somebody please help me? It is finals week, so this is like the worst timing ever!
Thank you in advance!

How do I login to my macbook pro if I forgot my password?

How do I login to my macbook pro if I forgot my password?

If the user account is associated with an Apple ID, and you know the Apple ID password, then maybe the Apple ID can be used to reset your user account password. In OS X 10.10 and later, this option also works with FileVault, but only if you enabled it when you activated FileVault. It's not retroactive.
Otherwise*, start up in Recovery mode. When the OS X Utilities window appears, select
Utilities ▹ Terminal
from the menu bar at the top of the screen—not from any of the items in the OS X Utilities window.
In the window that opens, type this:
resetp
Press the tab key. The partial command you typed will automatically be completed to this:
resetpassword
Press return. A Reset Password window opens. Close the Terminal window to get it out of the way.
Select the startup volume ("Macintosh HD," unless you gave it a different name) if not already selected. You won't be able to do this if FileVault is active.
Select your username from the menu labeled Select the user account if not already selected.
Follow the prompts to reset the password. It's safest to choose a password that includes only the characters a-z, A-Z, and 0-9.
Select
 ▹ Restart
from the menu bar.
You should now be able to log in with the new password, but the Keychain will be reset (empty.) If you've forgotten the Keychain password (which is ordinarily the same as the login password), there's no way to recover it.
*Note: If you've activated FileVault, this procedure doesn't apply. Follow instead these instructions.

I can't login into my macbook pro under my user , only as a guest.

My MacBook pro is taking forever to load. I can't login using my user name, but only as guest. When I finally make it into Guest User, it takes forever to load anything and everything. I want to know if I can still retrieve my pictures. I tried going thru iPhoto under guest user and importing the pictures. However, a red exit sign appears on all the files under that username. Please help ;(

Hi rosaqt,
I see that you are having some issues with your ability to log in to your user account on your computer. If this issue is related to passwords, you will want to see the information in the following article:
OS X Mavericks: If you forget your login password
http://support.apple.com/kb/PH14120
However, if this issue is unrelated to your password for your user account, you may need to provide more information in order for me to properly assist you. In the mean time, you may wish to boot into Safe Mode to see if that affects your ability to log in to your user account:

Login screen on MacBook Pro Retina (Late 2013) with enabled File Vault is extremely slow (suttering)

Hi
I have a MacBook Pro Retina (Late 2013) with enabled File Vault on OS X Mavericks. When I boot up the mac freshly it takes quite long to get to the initial login screen (which as I understand is a pre-boot login provided by the recovery partition if File Vault is enabled). However, what is even more bothering me is that once I get to this screen, the whole UI is behaving extremely slow. The mouse makes jumps of a few inches on the screen and the animations (e.g. if you click a user and then an animation shows the password entry field) are running in slow motion and only update every few seconds. Typing the password afterwards runs smothly again (altought for example moving the mouse at this point still behaves as described before). After loggin in to the account OS X runs fine without any hicks. Can anyone give me a hit what this could be and how I could resolve this?
This has already been done:
Reset PRAM
Boot into recovery partition and run repaired disk and disk permissions
Run all OS X maintenance operations and cleared caches using OnyX
What I could imagine is that somehow the recovery partition is damaged (which as I understand is used to boot to the login screen if File Vault is enabled).
Any help would be greatly appreciated.
Chris

Just ordered a Retina MacBook Pro11,2 (mid-2014 15", 2.2GHz Intel Core i7, 16GB RAM, 512GB SSD, OSX 10.9.4 Pre-installed - Build 13E28) and have the exact same issue. The first thing I did when i booted it for the first time was enable FileValut2 and encrypt the disk. Though I failed to notice this behavior prior to encrypting the disk, the stuttering/lag happens without fail every time I have logged in from a cold boot, locked screen or sleep. Additionally I have noticed the same stuttering behavior when switching tabs on various built-in OSX applications such as the tabs on the About This Mac > More Info.... (System Information) dialog for example, and similarly other dialogs that experience this behavior of resizing when switching tabs. I was running no other software than About This Mac > More Info ... (System Information) and OSX 10.9.4 itself. The issue happens without fail with and without a USB mouse plugged in.
I am really glad to have found this thread and with such recent posts. I'd love to find out that this is just a software bug that will be fixed when OSX 10.10 "Yosemite" is released. If not, I hope the cause of this bug is determined soon so I can still exchange or have it repaired.
Migflono and Matthew, would you be able to post your hardware specs for comparison?

Impossible login to the macbook Pro

Hi there,
I only have one user create in the system and I worked with my new MacBook Pro without problems, but I've installed a original software (iPass : with this software I can to connect to different wi-fi in airpots, hotels and so on all around the world). I restarted the computer and now I can't to connect. When I introduce the password the system tries to make the login but show me the login/password screen again and again. The passowrd is correct because if it's not valide credentials, the screen move from left to right.
Any idea how can I solve this issue?
Thanks in advance

Obviusly I can connect if I pay previously. With iPass my company pays for use it, so I don't pay nothing. But the question is ... what does it make iPass to my MacBook? I guess any changes in the priveleges or permissions, but I don't know. Any idea?
Regards

Frozen Login Screen on MacBook Pro 6,2 (Mid 2010) MacOS X Lion (Hardware or Software related?)

I have found the frozen login screen problem everytime I start my MacBook Pro 6,2 with Lion. I have tried everything from a simple "restore from a time machine back up" to a "clean Lion install" and the problem still appears.
Does anyone know if this problem is software or hardware related?
MacOS X Lion, Macbook Pro 6,2 (Mid 2010)

We just had the same problem with a 2010 MacBook Pro and Lion. The problem was solved by replacing the motherboard (thanks AppleCare...).
Hope this helps.

Cant login in my macbook pro

When i try login in my mackbook pro it accepts and everything but then this white background with a circle on the middle appears. What should i do??

Take each of these steps that you haven't already tried. Stop when the problem is resolved.
To restart an unresponsive computer, press and hold the power button for a few seconds until the power shuts off, then release, wait a few more seconds, and press it again briefly.
Step 1
The first step in dealing with a startup failure is to secure the 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 the last backup, you can skip this step.
There are several ways to back up a Mac that is unable to start. You need an external hard drive to hold the backup data.
a. Start up from 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.” The article refers to starting up from a DVD, but the procedure in Recovery mode is the same. You don't need a DVD if you're running OS X 10.7 or later.
b. If Step 1a fails because of disk errors, and no other Mac is available, then you may be able to salvage some of your files by copying them in the Finder. If you already have an external drive with OS X installed, start up from it. Otherwise, if you have Internet access, follow the instructions on this page to prepare the external drive and install OS X on it. You'll use the Recovery installer, rather than downloading it from the App Store.
c. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, start 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.
d. 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. You might be able to start up in safe mode even though you can't start up normally. Otherwise, start up from an external drive, or else use the technique in Step 1b, 1c, or 1d 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 startup failure can be resolved by resetting the NVRAM.
Step 4
If a desktop Mac hangs at a plain gray screen with a movable cursor, the keyboard may not be recognized. Press and hold the button on the side of an Apple wireless keyboard to make it discoverable. If need be, replace or recharge the batteries. If you're using a USB keyboard connected to a hub, connect it to a built-in port.
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 start up, and remove all aftermarket expansion cards. Use a different keyboard and/or mouse, if those devices are wired. If you can start up 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 started from an external storage device, make sure that the internal startup volume is selected in the Startup Disk pane of System Preferences.
Start up in safe mode. Note: If FileVault is enabled in OS X 10.9 or earlier, or if a firmware password is set, or if the startup volume is a software RAID, you can’t do this. Post for further instructions.
Safe mode is much slower to start 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 the login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
When you start up 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, the startup volume is corrupt and the drive is probably malfunctioning. In that case, go to Step 11. If you ever have another problem with the drive, replace it immediately.
If you can start and log in in safe mode, empty the Trash, and then open the Finder Info window on the startup 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 restart as usual (i.e., not in safe mode.)
If the startup 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 the 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 restart as usual.
Step 9
If the startup device is an aftermarket SSD, it may need a firmware update and/or a forced "garbage collection." Instructions for doing this with a Crucial-branded SSD were posted here. Some of those instructions may apply to other brands of SSD, but you should check with the vendor's tech support.
Step 10
Reinstall the OS. If the Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
Step 11
Do as in Step 9, but this time erase the startup volume in Disk Utility before installing. The system should automatically restart into the Setup Assistant. Follow the prompts to transfer the data from a Time Machine or other backup.
Step 12
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 startup 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 13
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.

AIM login problem on Macbook Pro

hi all,
i can't logon to aim with iChat (or Adium).
it doesn't seem to come from my network since i can logon to AIM on WinXP (using Trillian).
also, i tried to connect using my .mac account, and it seems that .mac is using the aim network?? (login.oscar.aol.com server)
this is really weird.
any hints?

Hi vvlinnzz,
How is your moemd set up to handle two computers ?
Are you using UPnP or Port Triggering that will allow multiple computers to use the same ports ?
Port Forwarding will generally point incoming data to one IP address only.
AS AIM and iChat both log on to AIM on port 5190 you may have problems with Port Forwarding.
In addition go to iChat > Preferences > Accounts
Select the account you are trying to Log on with
Go to the Account Info tab.
Whilst it is logged out of AIM select the third Check box (Allow Multiple Logins)
This will allow both computers or two different apps on the Mac to log in to AIM with the same Screen name.
If the account names are different and the @mac password is over 16 cahracters you will have problems.
Make the @mac password shorter (AIM only allows 16 .mac allows more)

Login problems on Macbook Pro

I have a machine that will only boot to the Administrator Account. The owner cannot boot in using her credentials until the admin password is entered and I log out of the administrator account. Can anyone tell me how to resolve this?

Surprised there hasn't been anyone else experiencing this issue.
I have seen this on 2 new MBP 2.3mhz i5's with the Intel HD 3000 384mb graphics, Lion 10.7.3 & 10.7.4.
Also with the latest Lion firmware for the late 2011 MBP's that addresses compatibility and stability issues.
Hopefully there is a fix soon because the painting on my locked screen to login is getting annoying

Sharing Music from different login accounts on a MacBook Pro

I just have a quick question. My wife sync's her iPhone to her account login on my MacBook Pro which is different from my login from startup. We share the computer but I got her, her own login so she could add and mess with the features she prefers. Anywho, I am curious if there is any way to share my music folder on my main admin user account on my MacBook Pro with her login account (we switch users, login and logout). Is this possible? Would make life a LOT easier. Hopefully this makes sense...we both just want to be able to sync the same music to our iPhones without having to backup all the music on my external harddrive and then load it onto her login account. I dont use Mobile Me.

You need a third-party program like one of those discussed here:
