Mountain Lion unable to start forbidden sign Harddrive problem

Hi guys,
so I have a MacBook Pro 17" with the newest Mountain Lion update and Bootcamp Windows 7. When I start the Mac, Mountain Lion shows me the forbidden sign, while still having this loading sign working but nothing happens and Windows shows me the bluescreen with the error code: "0x0000007B"
When I try to start the recovery in OS X the same happens (nothing...) and in Windows recovery the mouse and keyboard suddenly stop working so that I can't do anything. Additional to that I figured out that Windows has a problem with CLASSPNP.sys meaning that the problem lies in the hard drive. Now my question is since the mouse and keyboard stop working in Windows how can I reinstall the drivers in OS X?

Hi, this has worked for a few...
Make a New Location, Using network locations in Mac OS X ...
http://support.apple.com/kb/HT2712
10.7…
System Preferences>Network, top of window>Locations>Edit Locations, little plus icon, give it a name.
10.5.x/10.6.x/10.7.x instructions...
System Preferences>Network, click on the little gear at the bottom next to the + & - icons, (unlock lock first if locked), choose Set Service Order.
The interface that connects to the Internet should be dragged to the top of the list.
Instead of joining your Network from the list, click the WiFi icon at the top, and click join other network. Fill in everything as needed.
For 10.5/10.6, System Preferences>Network, unlock the lock if need be, highlight the Interface you use to connect to Internet, click on the advanced button, click on the DNS tab, click on the little plus icon, then add these numbers...
208.67.222.222
208.67.220.220
Click OK.
Also, turn off IPv6:
System Preferences » Network » AirPort » TCP/IP tab » Configure IPv6
Or whatever Interface you use.

Updated mountain lion today now can't sign in to access my computer

Updated Mountain Lion today and now cannot sign in to access computer. Changed my password on Apple ID but no luck. Talked to tech, not eligible for tech support. Can someone help......

You say 'sign in to access computer'. Are you talking about the main login screen when you first boot the Mac up? If so then that's completely different to an Apple ID and you need to go about resetting that PW in a different manner.
Apple ID's are used for purchases through the iTunes Store, the Mac App Store and for logging into iCloud.

I loaded Mountain Lion and now my Canon Canoscan LIDE100 Scanner won't work. I reloaded the application, checked the driver & loaded the Canon driver for Mountain Lion. Aplication starts to load then hangs up on 80% complete. Any suggestions?

Might have a hardware issue that was caused by the minor liquid spill.
Take it to Apple to have them look at it. I think they do a free diagnostics. That way you can find out what's wrong with your MB.
Good luck....Hope you get it sorted out.

After upgrading to Mountain Lion, Interface builder starts up with an error every boot.

I've got a late 2008 Macbook Unibody 13", and a few months back I upgraded from Snow Leopard to Mountain Lion. Ever since the upgrade, at every boot up Interface Builder starts up with an error. I've just ignored it mostly, but now I'm getting annoyed with it. How can I find the programs that start up every boot to research this, or stop it from loading Interface Builder every time?

You have to delete it using the minus sign at the bottom. The check/un-check is for hiding items.

After installation of Mountain Lion Unable to use Microsoft ----

After installing Mountain Lion I am unable to open Microsoft Word, Excel, Power point and entourage. Also Quark Express.
What do I need to do?

Hi babscott,
I assume you are using QuarkXPress 6.5 or earlier. As these are not Intel-native, these versions need Apple's emulation environment (called Rosetta) to run on modern Macs. Mountain Lion does not have Rosetta anymore.
So you need to upgrade to at least version 7.0.1 (9.3. is current) to get QuarkXPress to run on Mountain Lion. Upgrades are possible from any version.
As Csound1 correctly points out, QuarkXPress 9.3 is not yet officially certified on Mountain Lion. Still, most Quark users though can run it just fine on Mountain Lion. There is one known issue (besides the Gatekeeper limitation when installing) with some Graphics Cards, removing "Welcome Screen.xnt solves" that. More info here: http://forums.quark.com/t/28997.aspx?PageIndex=4#114829

OS mountain lion- unable to install

while upgrading and installation , system said hard didsk problems which is not repairable ( its been perfectly alright until today ) .. and now unable to install previous LION vers . I installed Lion from app store .. need urgent help please

Hope it helps!

Ibook doesn´t start (forbidden sign) after upgrade 10.0.4 to Jaguar

It´s appear a forbidden sign when the ibook start after install jaguar since 10.04.I´ve reseted pram open firmware,shift key etc..

You're Again Welcome juanelo!
"...install the Jaguar cd from Classic-9.2.2..."
So you were booted into OS 9.2.2, not running Classic through OS X, right?
Running Classic, is different than starting up in OS 9.2.2.
"...updatint the firmware."
Did you download and install, the Firmware Update, that was previously linked to?
And you did that, after you installed Jaguar 10.2.x?
"...using to upgrade to Panther the Install Cd,"
Do the discs look exactly like THESE, and do not say Upgrade, CPU Drop-in DVD, or "This software is part of a hardware bundle purchase - not to be sold seperately." on them?
"...added 512 mg of memory."
Are you sure this is compatible, working RAM, and is it new, or used?
"Sorry about the free disk space.I don´t want classic now just Panther."
So if the Hard Drive is 6GB, and it is empty now, did you Erase the drive?

Mountain Lion won't start with 32-bit kernal

I'm trying to update my Sony NEX-5 to version 5, and every time I click the installer, it says that it runs on a 32-bit kernal.
I tried starting up in 32 bit by holding the 3 and 2 keys, but this doesn't seem to do anything. I remember when I was on Snow Leopard, I could update my NEX-5 without any 32-bit startup necessary. Looking at some forums, even when people were on Snow Leopard they needed to startup in 32-bit...but I didn't.
Why doesn't it start up in 32-bit mode?
Why doesn't the application work on 64-bit? (Chrome is 32-bit...that still works on 64-bit)
Why has Sony even done this to us?
Running Mountain Lion 10.8.2 on the 2012 21.5" iMac.

Yes, the 64-bit kernel is not supported for downloading the firmware update. You may use your neighbors or friends computer to download the firmware. You can also send the Camera to our service center for getting the firmware installed:
Haha! Very funny Sony!
Well, I have a Canon 650D now anyway, and the update isn't a big deal. Just would be nice to update it.

Since upgrading to mountain lion unable to play dvd's

Since upgrading to Mountain Lion I am unable to play DVD's I get audio but no video

Perhaps your screen resolution got set back to default? Go to  -> System Preferences -> Displays, click 'Scaled' and try the different resolutions until you get to what you think you had previously.

Migrating from SnowLeopard to Mountain Lion does not start

Just got a brand new 15"MacBook Pro Retina running Mountain Lion.
First thing I tried to do after selecting language and keyboard was to try to migrate everything from my 15" MacBookPro running Snow Leopard but the process does not even start
After connecting both via ethernet cable, the computers recongnized each other, and I started the process but it has been showing "Preparing to transfer user documents for more than 4 hours"
No progress bar, no expected time for completion. nothing at all
Any suggestions on what to do?
Thanks in advance

After Bootup it wont back in normal Mountain Lion Osx, Longer start up time nothing normal

it was been unplug the power and put plug the power on back in and hit IMac turn power on while the Mountain Lion boot up but wont be back normal which
taken sooo Long cannot be back normal isnt same as Snow Leopard can do no problem exception Lion huh ? Can anyone know what to do ? to resolve the problem getting back normal Mountain Lion during start boot up time ?

Remove any items in System Preferences > Users & Groups > Login Items
Same for HD > Library > StartupItems
Check to see how much free space there is on the startup disk.
Click your Apple icon top left in your screen.
From the drop down menu click About This Mac > More Info then select click Storage from the menu.
Make sure there's at least 15% available disk space. Not enough free space can slow down the startup time.

Upgraded my 2010 macbook pro to mountain lion, unable to complete time machine backup using time capsule. Getting error 112

Upgraded macbook pro to mountain lion, get the following message
"the backup disk image "......." could not be accessed (error 112)
I've tried many of the suggestions from other discussion threads, still unable to get anything to work. Have 4 other computers backing up to the same time capsule, all of them are functioning normally, however they are not upgraded to mountain lion.
Suggestions?

This simple procedure will clear your Time Machine settings, including your exclusion list. If you have a long exclusion list that can't be recreated easily, you may prefer a more complicated procedure that preserves the exclusion list. In that case, ask for instructions. Otherwise, do as follows.
Triple-click the line below to select it:
/Library/Preferences/com.apple.TimeMachine.plist
Right-click or control-click the highlighted line and select
Services ▹ Reveal
from the contextual menu. A Finder window should open with a file selected. Copy it to the Desktop. Then move it (the original, not the copy) to the Trash. You'll be prompted for your administrator password. Reboot, recreate your settings in the Time Machine preference pane, and run a backup to test. If TM now performs as expected, delete the file you copied to the Desktop.
