Installed Mountain Lion really white screen then message error keeps rebooting

Mountain Lion white screen error message and keeps rebooting.

I'm not sure if this will help, but I was having a similar problem. I unplugged my external hard drive and it seems to have resolved the problem

Check to see if you have a folder named "Backups.backupdb" at the root level of your hard disk. That can cause this error message.

I erased my HD. Now I can't instal mountain lion from my bootable flash drive, and keep getting "installation error. Try again."

I bought mountain lion, made a bootable flash drive.
I booted from it and it went to upgrading right away!
So I stopped it and went to my former recovery partition I erased my HD because I wanted a clean start.
Now I can't instal mountain lion from the bootable flash drive, and keep getting "installation error. Try again."
and there is no 4 choices window.
I don't know what to do.

How did you create the USB install thumb drive? If it was with Disk Utility I have run into this problem and have since used THIS program to make the USB install drive.
As to your problem you only have one option and that is to Reinstall the Original OS X version that came on your computer or if you still have the Lion Recovery Partition use that to reinstall Lion. Or if you system came with Lion and you have No Lion Recovery HD Partition you can boot the system from over the internet and Reinstall Lion.
At startup hold down the Command+Option+r keys until you saa a spinning Globe in the center of the screen. Once that loads Repartition the drive as One partition and then reinstall Lion.

Installing Mountain Lion S.M.A.R.T. Errors

I am trying to install Mountain Lion on my macbook pro but I keep getting a pop up that says "this disc has S.M.A.R.T. Errors" what does this ,ean and what should I do?

S.M.A.R.T. is a built-in diagnosis routine in hard drives that checks various parameters to see if they drop below any thresholds, which may indicate an impending drive failure. Since it is better to be safe than sorry, I recommend you replace your computer's hard drive. You can also try seeing if other drive utilities detect similar problems with S.M.A.R.T. You might try using SMARTreporter or SMARTutility for OS X, or a full disk management suite like Drive Genius to do this.

Cannot install Mountain Lion as the installer provides message that my target drive is using Time Machine. My target drive is my internal drive and I use an external drive for Time Machine. When I check the Time Macine set up under system prefereces it sh

Cannot install Mountain Lion as installer sys the target drive I have selected is using Time Machine. The target drive I selected is my internal drive. I have an external drive that I use for Time Machine backup. When I go to System Preferences and look at the Time Machine set up it shows my target disk is the external drive. What to do?

Yes, you’ll be able to do that.

Unable to install Mountain Lion - S.M.A.R.T. errors My hard disk error?

Unable to install Montain Lion after purchasing form store and download on Mac Pro 13 inch 2.3 Intel i5 OS 10.7.4. When I am presented with install options, my HD option is dimmed and there is a message: "This disk has S.M.A.R.T. errors. This disk has a hardware problem that can't be repaired. Back up as much of the data as possible and replace the disk."

Well that's good advice. SMART errors are only presented when the hard drive is about to die. This is a dire warning.
You should ensure you have a current backup, and then replace the hard drive. You may need to take it into an Apple Store... if it's < 3 years old and you have AppleCare they will probably replace it for you.

After installing Mountain Lion, why screen server does not detect photos from iPhoto?

After installing Mountain Lion, why the screen server does not detect photos from iPhoto?

I had the same problem and found the solution here:
https://discussions.apple.com/thread/3189272

Installing Mountain Lion from Snow Leopard, Install failed and HD write-locked

I recently downloaded the mountain lion installer from the App Store and I ran the installer. Stupid person as I am, I did not have any backups for my file and I naively assumed that an apple OS installer would be without flaws. Boy, was I wrong. I need every bytes of my data (or close to every bytes) but the installer failed.
Mid installation, the installer stopped and said that the installation failed and that I need to repair my disk. So I restarted the computer and I ran disk utilities (my start up disk was the OS installer and the installer allows me to run several programs, including terminal, disk utilities, and by the way, when I held option while starting up to see which start up disks I have, I only had the OS installer as the start up disk. Also, the installer allows me to run a program called "Startup Disk" when I click on the apple logo on the top left corner, but it doesn't allow me to startup my computer using Macintosh HD) and noticed that when I highlighted Macintosh HD, my "Repair Disk" button was grayed out. So first things first, I ran the "Verify Disk" button but after a minute or so, Disk Utilities said that verification failed and that Macintosh HD needs to be repaired. But the "repair disk" button is grayed out! So I went to the Mountain Lion installer again and ran it. Of course, it failed again so I restarted the computer.
So I tried to first back up all files in Macintosh HD to an external hard drive using Disk Utilities, and I used features such as "New Image" and "Restore" but they both ended up in "Input/Output error". I tried many methods with Disk Utilities but they resulted in errors.
After some research, I noticed that some people's computers worked after they reset their PRAM. So that's what I did. I held command+option+P+R when computer started up and I reset the PRAM. When the start up disk (which is the OS installer, not the normal operating system) loaded, I was greeted with choose languages option and then I was back in the Mountain Lion installer state. I again ran the installer again, hoping something would be different, but then it was different. But not in a good way. When I was told to choose where I would like to install Mountain Lion, I noticed that Macintosh HD was grayed out. Last time, I was at least able to run the installer but this time, Macintosh HD was grayed out. The installer said that my Macintosh HD was locked. After some research, I learned that apparently, the Mountain Lion installer write-locks Macintosh HD mid installation.
So now I am stuck and I am thinking of two things (plus some questions)
1. I am wondering if there is a way to unlock Macintosh HD. But even if I can unlock Macintosh HD, there is no guarantee that the installer will successfully install Mountain Lion, am I right?
a. so how can I un-write-lock Macintosh HD?
2. More realistically, I am thinking of borrowing someone else's macintosh computer and use it as the backup center. I have a firewire cable and a terrabyte external hard drive. So what I'm thinking is that I'll hook my computer in target mode to my friend's computer and I will also plug in my external hard drive to my friend's computer and then I can download and run Carbon Copy Cloner from my friend's computer to copy all data from my Macintosh HD to my external hard drive. And then I will erase my Macintosh HD, freshly install Mountain Lion onto it and then copy all data back from my external hard drive. But I am not sure about few things.
a. it looks like my Macintosh HD is write-locked. Can I still use Carbon Copy Cloner to copy all data from Macintosh HD (in target mode) to my external hard drive?
b. will my computer allow me to erase (or format) Macintosh HD?
c. will my erased/formatted Macintosh HD able to install + be installed Mountain Lion OS?
If you are here, then you have read my long long problem. Thank you very much and I would really really really appreciate your answers and opinions. Thanks

I'm not sure where you read that about the disk being "write-locked." That doesn't make much sense, given that the major task an installer like this must achieve is writing a whole bunch of files to the hard drive. I think your source was mistaken.
As to what happened, it sounds like your hard drive was badly corrupt to start with, or possibly was on the edge of failing and is now in the process of dying entirely. If you don't have backups of your data, that does not bode well for you, unfortunately. If you can manage to use target mode to copy your data, do that.
Once you're sure you've got all your data, you need to start up from your Snow Leopard install disk and repair the hard drive. (Since it sounds like the Mountain Lion installer didn't work, I wouldn't trust the recovery partition that Mountain Lion installs.) Or, even better, just erase the hard drive entirely and reinstall Snow Leopard. Then, once you're back up and running, with all your data back on the system and with Snow Leopard updated to the most recent version, try installing Mountain Lion again. If any of that fails again, the problem is likely to be a dying hard drive, and you'll need to replace it.

I installed Mountain Lion and now some times when I start my mac it look with a black screen and white text. I'm really worry about it, can somebody help me?

I installed Mountain Lion in my IMac and now, some times, when I start up my mac it looks with a black screen and white text. I'm really worry about it, can somebody help me?

Don't worry, this is probably just Verbose Mode. It's perfectly harmless. If you're not specifically invoking it, than it's probably down to an unwanted setting in NVRAM. See this article on resetting NVRAM if it continues to bother you.

Mountain lion really bright white screen on boot?

Since I installed Mountain Lion I can't seem to get rid of the really bright white screen with Apple logo at bootup.
I RESET the PRAM and it will work for one boot and then go back to the really bright screen burning my irises out.
It can't be the battery because my computer keeps the time and date correctly.
I have also checked the STARTUP Disc and that is working right too. I even tried redoing permissions through Disk Utility and that didn't help.
Anyone have any ideas on this one?
Thanks.

Anyone have a answer to this?

I just installed Mountain Lion. I'm having an issue on the log in screen.

Hello,
I just installed Mountain Lion 10.8.2 on my iMac. We have four user accouts on the computer and when you first wake the computer where you would normally choose an account and log in the screen is white. When you move the mouse around it leave a little trail of the log in screen until you find your acct and click on it and then it allows you to log in. Its never done that before, at least until I upgraded. This computer was bought right before Lion came out and I didn't upgrade it right away because I wanted to wait and see how everyone else liked it. I finally upgraded last week and aside from this issue it works great and I love the features but it is really annoying. What should I do? Has anyone else had the problem? I upgraded my Macbook and it hasn't had any problems but I only have one acct on it since my wife and kids don't use it. Thanks for the help in advance.

Contact Apple Service, iMac Service or Apple's Express Lane. Do note that if you have AppleCare's protection plan and you're within 50 miles (80 KM) of an Apple repair station, you're eligible for onsite repair since yours is a desktop machine.

So I click on Repair, and once again I'm prompted for a password, which I enter, then the same error box opens, and so it goes. Can anyone help me with this problem? I'd greatly appreciate it.

Back up all data. Don't continue unless you're sure you can restore from a backup, even if you're unable to log in.
This procedure will unlock all your user files (not system files) and reset their ownership and access-control lists to the default. If you've set special values for those attributes on any of your files, they will be reverted. In that case, either stop here, or be prepared to recreate the settings if necessary. Do so only after verifying that those settings didn't cause the problem. If none of this is meaningful to you, you don't need to worry about it.
Step 1
If you have more than one user account, and the one in question is not an administrator account, then temporarily promote it to administrator status in the Users & Groups preference pane. To do that, unlock the preference pane using the credentials of an administrator, check the box marked Allow user to administer this computer, then reboot. You can demote the problem account back to standard status when this step has been completed.
Triple-click the following line to select it. Copy the selected text to the Clipboard (command-C):
{ sudo chflags -R nouchg,nouappnd ~ $TMPDIR.. ; sudo chown -Rh $UID:staff ~ $_ ; sudo chmod -R u+rwX ~ $_ ; chmod -R -N ~ $_ ; } 2> /dev/null
Paste into the Terminal window (command-V). You'll be prompted for your login password, which won't be displayed when you type it. You may get a one-time warning to be careful. If you don’t have a login password, you’ll need to set one before you can run the command. If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator.
The command will take a noticeable amount of time to run. Wait for a new line ending in a dollar sign (“$”) to appear, then quit Terminal.
Step 2 (optional)
Step 1 should give you usable permissions in your home folder. This step will restore special attributes set by OS X on some user folders to protect them from unintended deletion or renaming. You can skip this step if you don't consider that protection to be necessary, and if everything is working as expected after step 1.
Boot into Recovery by holding down the key combination command-R at startup. Release the keys when you see a gray screen with a spinning dial.
When the OS X Utilities screen appears, select
Utilities ▹ Terminal
from the menu bar. A Terminal window will open.
In the Terminal window, type this:
res
Press the tab key. The partial command you typed will automatically be completed to this:
resetpassword
Press return. A Reset Password window will open. You’re not going to reset a password.
Select your boot volume ("Macintosh HD," unless you gave it a different name) if not already selected.
Select your username from the menu labeled Select the user account if not already selected.
Under Reset Home Directory Permissions and ACLs, click the Reset button.
Select
 ▹ Restart
from the menu bar.

My MacBook Pro mid 2010 was upgraded to mountain lion os x and then my wifi started saying no hardware installed

My MacBook Pro mid 2010 was upgraded to mountain lion os x and then my wifi started saying no hardware installed

Hello Harrisonhcue,
I would be concerned too if I was getting the message "no hardware installed" when trying to use Wi-Fi on my MacBook Pro. For a message like this, I recommend resetting your System Management Controller (SMC) and NVRAM.
Resetting the SMC on portables with a battery you should not remove on your own
Note: Portable computers that have a battery you should not remove on your own include MacBook Pro (Early 2009) and later, all models of MacBook Air, and MacBook (Late 2009).
Shut down the computer.
Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected.
On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.
Release all the keys and the power button at the same time.
Press the power button to turn on the computer.
Note: The LED on the MagSafe power adapter may change states or temporarily turn off when you reset the SMC.

Resetting NVRAM / PRAM
Shut down your Mac.
Locate the following keys on the keyboard: Command (⌘), Option, P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on the computer.
Press and hold the Command-Option-P-R keys before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys.

TS3147 After installing Mountain Lion, I tried to scan from my Canon MX870 and received the message: "MP Navigator EX quit unexpectedly. Click Reopen to open the application again. A report will be sent to Apple,"

After installing Mountain Lion, I tried to scan from my Canon MX870 and received the message: "MP Navigator EX quit unexpectedly. Click Reopen to open the application again. A report will be sent to Apple," This problem happened right after I installed Mountain Lion. I then downloaded Canon's upgraded software and drivers for the MX 870 and the problem was resolved. Now one month later, the problem has returned.

Solved problem with original Canon software. When I downloaded Canon software upgraded for OS X 10.8, I got all by Navigator Ex. Noticed that on Canon's site, the upgraded version is 3.1; my app was 2.1. Upgraded to 3.1 for Nav. Ex, and it works.
You should still use Image Capture IMHO. If it was my gear, that's what I would do. No need to worry about software upgrades.

Installed Mountain Lion really white screen then message error keeps rebooting
