Can't login on startup... HELP!

For the past half year now I've been having problems with my Mac lagging with the rainbow wheel showing up (but not really my main issue right now.) My big problem now is that i just pressed "install updates" and agreed to restart my Mac. As soon as it turns on again and i try to log in, the whole screen turns white-grey then just flashes back to the login screen. Password isn't wrong nor can i just go in as a guest bc it does the same thing... I noticed some people said they had this trouble with some kind of authenticity software..? But i don't have that so it's got to be something else...
Help please! (i didn't even get to back up anything )

What model Mac (This is the Mac pro desktop forum) and what OSX version?
How much memory?
How much free disk space on startup drive?
Try booting in Safe Mode
OS X: What is Safe Boot, Safe Mode?
Try either booting to Recovery (Lion and later)
OS X: About OS X Recovery
Ot with an install disk and repair the startup drive.
Also, when in Disk Utility see if bu the S.M.A.R.T. entry there is anything but Verified listed.

  • My battery died while I was powering down my computer. Now I can't login. Please help?!

    Hi,
    I was in the process of powering down my computer when the battery ran out of power. Now after I have typed my password  to login and pressed Return nothing happens. I can move the mouse but everything else freezes up and I can't click on anything. The only thing I can do is to manually power it down with the power-button. I am using Time Machine and therefore I re-installed a copy that was one week old but the same problem still exists.
    What do I do now?
    I have the first version of Macbook with the aluminum body.
    Thanks for the help!

    I am not sure how you re-installed from Time Machine, if you can't click on anything?  Anyway, with the power chord connected (since the battery is flat), try an SMC reset as described in the link.

    If this doesn't improve the situation, I would suggest holding the Option key during a restart and selecting the Recovery partition, from where you can verify the disk and repair permissions and ultimately to do a re-instal of Lion if necessary.

  • GE60 0NC-622UK laptop is stuck on Blue Screen can't login! please help..

    Had this laptop for just one month, before it's all good. Windows 8 64bit.
    In last two days, the mouse and touchpad became dysfunctional occasionally, able to move the pointer but just could't click on anything regardless of left or right, e.g. choose or open new. It would be working after logoff/relogin and reboot, but same problem still came up randomly.
    Last night, I did the same thing to reboot the laptop after had the pointer dysfunction, but then it displayed a blue screen before the login with a error called 'System Thread Exception Not Handled', and then just stayed on this page would't reboot automatically (waited for 30 mins), so it left me no choice to shut it down by pressing power on/off button manually, afterwards with couple of times rebooting, it just kept going into this same blue screen and could't get into the system...Sometimes it would automatically start diagnosing before blue screen, ask me to restore or repair, but none of them fixed the problem, repeatedly stuck on blue screen every time...
    And I don't have any windows 8 dvd, delivered box only has one for drivers and manual book.. so boot from dvd is not possible..
    p.s. sorry about my english if caused confusion
    thanks..

    Try starting Windows 8 in Safe Mode, its kinda difficult in Windows 8 to do you have to be very precise when doing it, right as the system boots you need to start spamming F8 sometimes you have to do Shift+F8.
    You may want to disable fast boot in the BIOS so you have some time to get ready to hit the buttons, once you get the boot menu up try Start Up Repair first and see if it fixes anything then try booting, if noting then try safe mode and un-do anything you have done to the system recently.
    Let me know how this goes.
    Really appreciated your help!
    I get into troubleshooting page by pressing F3 when laptop was booting up, and changed start up with Safe mode which works..I've done many things in Safe mode, like updated drivers, run anti-virus program, deleted recent installed software, and then somehow the blue screen error was gone after reboot...It seems one of them must be the cause for that problem.
    Anyway, my laptop is working properly now, thanks a lot, if error happens again in future i might still need some help

  • I was emailed my user name, then a password and reset link, I reset password, and I still can't login. Please help.

    Along with the above info, I can't log in on the mozilla support website to post a question. Not really any more information, other than 18.0.2, Windows 7 Home Premium, x64.

    Many site issues can be caused by corrupt cookies or cache. In order to try to fix these problems, the first step is to clear both cookies and the cache.
    Note: ''This will temporarily log you out of all sites you're logged in to.''
    To clear cache and cookies do the following:
    #Go to Firefox > History > Clear recent history or (if no Firefox button is shown) go to Tools > Clear recent history.
    #Under "Time range to clear", select "Everything".
    #Now, click the arrow next to Details to toggle the Details list active.
    #From the details list, check ''Cache'' and ''Cookies'' and uncheck everything else.
    #Now click the ''Clear now'' button.
    Further information can be found in the [[Clear your cache, history and other personal information in Firefox]] article.
    Did this fix your problems? Please report back to us!

  • Help: I can't login

    Hey Guys,
    This is another "can't login" problem.
    I've already read the other threads on this problem, but still it's not fixed yet.
    So, the story is, i installed fedora on another partition in my laptop. I dual boot between archlinux and fedora now.
    The login problem occurred after i installed fedora. But im not sure whether that had to do with the login problem.
    I already followed some tips from the thread i read:
    1. export $DISPLAY=:0.0 on console. and then startkde
    didn't work. i got something like "cannot connect to X"
    2. try startx, didn't work either.
    3. One of the thread advised that i deleted folder .kde4, but i just renamed it to ._kde4 (doing this is not different with deleting the folder right?)
    Still, the problem is not fixed.
    4. I install fam, because previously i used gamin.
    5. I add a new user, hoping that this user can login. But no luck here.
    But some strange things happened when i login using console.
    1. It says that my user (keripix) doesnt have a directory or something like that. And when i "cd /home/keripix" it told me that i dont have the permission.
    2. Every time im trying to run as root, im always told that authentification fails. This is strange i think, because im able to login to console using "keripix" and my password.
    Right now im very desperate. I need my arch for my big project for my final year at uni. im not thingking about reinstalling my arch, because i have some important data. And i dont know how to move them to a different place (postgresql data). And im not thingking of changing from arch. I just love arch.
    Please help. It would be very helpful. Thanks in advance.

    So I suggested that you first solve that problem for safety's sake, just in case something might get worse when you try to fix the other issue.
    I still think that it would be wise for you to have a backup or a copy of your data files somewhere in a safe place.
    It seems to me that you should consider it urgent, especially when there are other problems with your installation.
    Oh...so i misunderstood. Thanks berbae.
    Here, here.  Good tip MadTux.  This is what I'd think by reading this thread.  Your install of fedora whether intentional or accidentally has now become permission-owned by the user you created in fedora.  If this is that case just changing permissions recursively to your arch ones should do the trick.
    OK...i'll try to do this on arch.
    Btw, now i can login to my arch. But i use slim instead of kdm. However, still, there's a lot of problems. Such as i can't use applications that need root permission. Also, i cant become root as well.
    Konsole also breaks somehow. There's no text in the konsole screen (sorry im not sure what you actually call for the black space you type those commands )

    I am getting ready to buy my new MacBookPro next week and wanted to give my old Powerbook Ti to my sister. But she didnt want to get the login screen everytime just want to power up and start working. So after going threw a few forums I deleted the root netuser.

    How did you delete the user account? How many accounts did you have? The "Accounts" System Preference should not have let you delete the last administrator account. If you still have an administrator account, you can reset its p[password by booting from the Tiger install disk. After setting language, look in the menus for password resetting.

    Hello,
    Have you upgraded to BBM7? if yes i would recommend downgrading because for some people quite a number of problems has been caused affecting the whole phone and not only BBM.
    If that isnt the case, you will have to do a soft reset on your phone and my recommendation is to either create a new BlackBerry ID or try your best to configure your old one with the phone, whilst everything that isnt back up will be removed

    If you are asking what happens when you delete an iCloud backup, it only deletes the backup from your account.  It won't do anything to the data on your phone or in your iCloud account.  If you don't need to backup you can delete it.  (If you no longer want to back up your phone to iCloud, turn iCloud backup off in Settings>iCloud>Backup.  Then your phone will back up to your computer each time you sync it with iTunes.)

  • Can't login to Gmail because I don't have cookies enabled. Help?

    I can't login to Gmail. It says cookies are turned of, but they ARE turned on. I have tried everything, including reinstalling firefox, but nothing helps.

    I have the same problem and to get it to work I have gone into Tools, Options, Privacy, Show Cookies and deleted all cookies, then go to the Advanced tab, find Cached Web Content and click the Clear Now button. After you cleared the Cache restart Firefox and it works normal, but only for so long, in my case 1 day, then I had to do it over again. This has been happening since I went from Firefox 16 to Firefox 17.
