Mountain Lion going into safe boot

Hi, I downloaded mountain lion and it started intstalling. When it restarted to install the upgrade, it starts in safe mode..i tried shutting down and restarting few times but every time it starts installing the updates and then goes into safe boot mode..
Note: yesterday I got a problem with my key board, there was a spill into my mbp keyboard and most of the keys are not working. Right now i am using my Bluetooth keyboard now.
Pls let me know how to fix this safe boot issue with the installation.

A problem with a keyboard will cause your Mac to startup in Safe Mode.
If you can, use a USB keyboard instead of Bluetooth.

My macbook pro automatically goes into safe mode and doesn't start. I use mavericks. what to do? ?

Can you boot into your Recovery partition (hold down the command and R keys whilst booting)?
Call back - you'll be able to connect to this forum from Safari whilst in Recovery.

Wifi goes on and off, backlit keyboard doesn't work and no sound since Lion upgrade. I can get the wifi back by going into safe mode and re booting(someone suggested on here), but can't let computer die or turn off or have to do it again.

My Wifi connection goes off if computer dies or shuts off, I can only make it work if I go into safe mode and reboot, it was just that, but now my keyboard doesn't light up like it's supposed to in low or no light and in system preferences it's like it doesn't exist. Also, the sound doesn't work, I can't turn it up or down, it shows the sound icon grayed out and the anti symbol when I push F11 and F12, also it's like it doesn't exist in system preferences either. I have never had any problems with my MB Pro, I purchased in Feb. 2010. , but I upgraded to Lion last month, I haven't been using my laptop as much since I had an Ipad I given to me, so I think that's why I didn't notice these issues right away. What do I do? HELP!! Do I take it to Apple? I don't have the Apple care warranty, so will it be expensive for them to fix? Can I get my money back for Lion if I restore to Snow Leopard?

Take it to an Apple store or AASP. How much it will cost will depend on their determination of the problems. To bad you didn't purchase extended AppleCare. No you don't get your money back for purchasing Lion.

HT201240 Macbook goes into "Safe Boot" mode when I start it but it will not accept my password to complete the boot.

When I start my Macbook it tries to start in Safe Boot mode and it will not accept my password. I have tried to reset the password by inserting the "Mac OS X Install" disk and restarting while pressing C but that process has no effect. The same Safe Boot screen appears and again it will not accept my password.
I am not sure what version of MacOS X I have as the disk is now in the machine and it will not eject.
Any suggestions?

You can eject the disc by depressing the track pad/mouse at startup.
Are you depressing the Shift key at startup to make the Mac boot in Safe Mode?
Here's the instructions if you have the discs.

Equium A100 black screen on startup

Toshiba Equium A100 laptop
Completely black screen on startup so please don't say go into safe mode etc, because I can't.
I can't see a thing.
Like once in every 100 goes it will come on and I can F12 to boot from the format disk but it eventually freezes before completion.
Video showing what's happening - BTW the buttons you see me pressing are Fn+F5 I've heard that that sometimes works, but yeah, it didn't.

Hi
Look not good dude I think its an serious hardware issue
I checked the movie and cannot hear a beep when the notebook passes the POST (power on self-test). So for me it looks like something wrong with the hardware
But did you try to connect an external monitor in order to check if something would be visible on second screen? Check this
You could also try this:
Disconnect AC adaptor, remove the battery, wait some time (3-5 hours), then connect both parts and try to power up the notebook. If this fails, well in such case have no many other ideas. Ohhh wait maybe you could check the RAM modules. Try to power up the notebook using one module in each slot

HELP! Black screen after startup after Yosemite installation

Urgent help please.
I Have a late 2010 MacBook Pro and today installed Yosemite. It appeared to install ok, but now on startup it gets past the apple logo screen then just goes to a black screen with a cursor. I have attempted a safe boot, and it manages to get to the login screen, but it won't accept my password, it just keeps on loading the login screen over and over. Would love an answer please...I am completely puzzled!

Ok, I am a couple of days ahead of you. I had exactly the same issus on a mid 2010 mid MBP. Mine failed after the install, although it worked fine for a few minutes untill it went into Sleep. When it came back on it was in color But you could not really see, Another reset and all went black.
After an hour on the phone with support on Sunday who suggested trying a system management reset. Solved nothing. I went to my Genius apt on Monday. Two hours and 15 minutes waiting in line And finally I got my Genus.
Again a nice guy trying to help, but other than pulling the connector to the screen and getting back my comprised color negative screen no real progress. "I know it sounds like a strange coincidence but maybe you display went bad." Well perhaps you can get hit by lighting twice in a row while humming "Oh, What a beautiful morning" but I did not think so.
I was more lucky back at home. I recently installed an SSD, so I took it out and booted with the old drive and booted 10.9.5. Display was fine. So this proved the issuse was Yosemite install. Here is the good news, when I put the SSD back in everything was great. i know you can't do exactly what I did. Here is what I suggest..
I believe the issuse is bad video driver with Yosemite during the install. rreinstall Maverick or boot from another drive with OPTION. . I believe it will work fine. Then if you are lucky perhaps your Yosemite will work as mine did...

Black screen on startup with a mouse pointer but can't do anything???

Hello,
I've read all the posts in regards to this topic. Nothing has worked. I have my brothers HP laptop with Windows Vista. I thought the Hard Drive (HD) crashed because all I had on start up was a black screen with a cursor. When booting I am given the option to start up in Safe Mode, Safe Mode with Command Prompt, and Safe Mode with Networking. No matter which one I choose I get the same thing - black screen with a cursor. I can move the cursor around. Nothing happens when I hit Ctrl+Alt+Del. When I hit the **bleep** key 5 times the widow comes up about the Sticky Keys - the paragraph asks me if I want to enable them but does not give the the option to click on a "yes" or "no"; My only option is to click the X to close the window. If I use the short cut keys for the Windows Utility (windows key = u) I get an error message basically saying it can't find the file.
I have a Rocketfish HD Enclosure for SATA drives. So, I removed the HD from the HP and plugged it into my other computer (an Acer) with the enclosure. I ran Norton AVI & Spy Sweeper. Norton removed & resolved 2 Trojan viruses. My brother was not using Norton or Kaspersky, or McAfee - or any other AVI software that is worthy... obviously - he got 2 Trojans! Spy Sweeper ran overnight and half a day (16 hours) - didn't finish and found nothing during that really long time span. He apparently partitioned his HD himself. When I hook it up to my computer it shows up as 3 different HD's. One appears to be just back up files and that part of the partition is FULL. One has pretty much nothing on it, and the other appears to be the main one he is/was using because that's where all the program files are. I can successfully navigate through all 3 partitions. I copied all his documents, pictures, files, Mp3's, etc to my own external HD. I can see his entire OS is there... his HD is FINE as far as I'm concerned.
I put it back into his laptop and the same thing happens... black screen with cursor.
I can get into BIOS. In BIOS I ran the HD diagnostic, it says to replace the HD. I let it go ahead and do the memory diagnostic test in BIOS for the heck of it and of course that's fine - he's got 4gb.
I did something else in BIOS - restoring? It restarted and did nothing...
I tried hooking up MY own personal old HD (with entire OS still on it) via my SATA enclosure to his laptop and still nothing... so, it won't recognize any OS.
I have ruled out - in my belief that his HD is okay. Especially now that I have removed the viruses.
I have not figured out what the problem is though. I can't get in - it seems to not recognize the HD - it won't boot from the HD - I can't get into C:\ from anywhere to even try to get up Windows Explorer.
I'm thinking other hardware failure... fried motherboard?
So, I'm not completely computer illiterate. But, hardware trouble shooting is not something I've had much hands on experience with. I can write lines of code in several languages... but hardware troubleshooting does not seem to be my best subject... (I'm still in school for my BS in IT).
My brother thinks his laptop is trash - I think his HD is okay - he may still be able to use it as an external HD if he gets an HD SATA enclosure like mine. But, this poor laptop has survived Hurricane Gustav - where he lost his home in Baton Rouge, LA and therefore I'd like to fix it, I know I can fix it, but I have to know what's wrong with it in order to fix it...
I'd appreciate any useful suggestions! If it is a motherboard issue... I wonder how hard they are to replace
P.S. - it's a HP Pavillion dv6500 Entertainment PC
P.S.S. - I'm going to open it all up tomorrow & clean it - who knows the last time he cleaned it, if there's a lot of dust in there it could be a big problem. Just running it today it got VERY hot and the fans seem to be running very loud (as compared to my Acer laptop).

A hard drive if it has failed will sometimes allow you to boot into windows but may not work completely (Eg: In a scenario, where system partition ;where windows is installed works fine but logical partition of hard drive has gone bad).
On certain conditions, if the hard drive is on verge of failure may/may not respond completely. I would suggest you to run a diagnostics using Seagate Seatools which works on any hard drive irrespective of manufacturer to actually confirm if your hard drive has failed.
Also, any hard drive can fail in spite of it been 1yr old or 1day old as its all manufactured in bulk and most of it comes from China

IMac randomly booting into "safe boot" mode after a clean installation of OS X Lion 10.7 (??)

Is anyone else having problems with their Mac (running a clean installation of OS X Lion 10.7) randomly booting into "safe boot" mode after a restart or shut down?
(Indicators being: seeing the login screen even when "automatic login" is enabled, the proper video drivers not loading - indicated by laggy desktop animations, WiFi not working properly, Menu Bar icons that normally show - not showing, etc.)
**Note: I migrated from a Snow Leopard Time Machine backup, but did not import "Settings". I thought this would be the best way to keep from encountering any issues with 10.6/10.7 incompatibility.

Found this answer from another user. THE EXACT THING HAPPENS TO ME:
Its really annoying Apple hasn't fix it.
=================
I think i got it :
The progressbar while booting ( booting in safe-mode ) came from the wireless keybord and is reproduceable.
At evening I shut down my iMac an put off my mouse and keyboard. To startup I put on the iMac and immediatly after I switch on keyboard and mouse. In tihs case the keyboards sends some event wich leads to safe-mode.
Know I wait until I switch on the keyboard. In my opinion this is a bug, i can live this way but i hope it will be fixed.
I will know take a look at it while not switching off the keybord, power consumption should be acceptable

Leopard always boots into Safe Boot

Every time I restart Leopard it boots into "Safe Boot" mode. To get it to boot into regular mode I have to keep hitting "x" after the startup sound while booting.
I read that Leopard shouldn't boot into safe mode unless I hold down the shift key when starting up. My shift key isn't stuck down (I wouldn't be able to type this message in lower case if it were). But Leopard insists on booting into safe mode by default.
I applied the latest updates just this morning. So everything is up to date.
What can I do to get Leopard to boot by default into normal mode again?

Maybe I need more specifics. I clicked on the Apple menu in the topbar and clicked Restart. I then clicked Continue when prompted to restart immediately. I then held down the Command, Option, R and P keys. While holding down the keys I heard the startup chime once (not twice) and my computer started normally.
I'm wondering if I did the right thing since I didn't hear the second startup chime.
Did I miss something?
Thanks so much for your help.

Why can't I boot into safe boot mode?

I can't seem to boot my Mac Pro (mid 2010) into safe boot mode. Hold down the shift key and it starts, but the progress bar never goes more than 1/3 and the gear just spins. Any suggestions of what this means and how to fix it? OS 10.6.8.

I have had the exact problem for a while. I finally tried a suggestion from applecare. I had a spare hard drive, erased it, reinstalled mac OSX 10.7 (the issue occurred with 10.6 and 10.7 on my Mac Pro system) and rebuilt my entire system one program at a time. I would safe boot between installs, looking for the culprit (applecare suggested it was likely a third party vendor install that created the problem.) I installed multiple programs, tested safe boot without a hitch. The problem occurred after I installed ReadIris Pro (a comprehensive scanner and OCR program). It created this very problem you and I both seem to have.
Please respond if you have this software package (or any of the IRIS family programs). It is possible it changed a configuration file or interacts with something else on the system. Simply deleting the program does not seem to undo the problem.

When I open Firefox, my computer goes into safe mode. How do I fix this problem?

When I open Firefox to do some browsing, my computer goes into safe mode. When I close Firefox browser, then it goes back to normal. I know there has to be a simple fix, but I have not found it.

Check that you do not run Firefox in compatibility mode or with a reduced screen resolution.
You can check that in the "Compatibility" tab in the Properties via the right-click context menu of the Firefox desktop shortcut.<br />
Make sure that all items are deselected in the "Compatibility" tab of the Properties window.

Unable to restore screen when laptop goes into power saving mode

Toshiba Satellite M45 running MS Windows XP, When laptop goes into powersaving mode and screen goes black, if i do not move the mouse in a nanosecond I am unable to restore the screen. Try my ususal fix of pressing the now amber mechanical start button, but I only hear the computer start to whir, but the black screen continues. I have to do a hard close and consequently loose all unsaved data. Then do a mechanical start and return to the desk top with a message that the computer programs where not closed properly.
I have been told I need to change the power saving mode options. Is this correct? How do I do this? Thanks, Blooming

I tired to do a system restore for two different dates and got a message that MS was unable to restore to that/those dates. - no explanation.
Linda, sometimes the restore points get corrupted. The fix is to turn System Restore off and then on again. Unfortunately, that removes all the previous restore points.

You might try running the System File Checker.
