Can't boot SL 10.6.3 in normal mode, works in Safe Mode

I took receipt of a new i7 MBP with high-res screen a few days ago, and have been struggling to get it to work right.
I swapped my 256 Samsung SSD from my previous MBP (Unibody with replacable battery, 14 months old), which seems the main reason for the trouble.
Here's an overview of what happened:
First attempt:
- Started new MBP with original hard drive, ran through setup process and all worked fine.
- Swapped the original HD with the SSD from my old MBP
- Booted new MBP with SSD, got stuck at the grey screen with Apple logo
- Tried booting into Safe mode, no luck
- Booted in verbose mode, the boot process got stuck when loading Extensions.mkext
Cleaning Caches:
- Connected MBP in Target mode to another machine
- Removed all cache files from the drive using Snow Leopard Cache Cleaner
- Rebooted MBP, same issue as above, couldn't get it to boot
Formatting drive:
- Because I was planning to recondition the SSD anyway, I made a clone of it and formatted the drive.
- Used DiskTester to recondition the SSD drive
Reinstalling SL:
- Using the SL DVD shipped with the MBP, I installed a fresh OS
- After installation, all worked fine again
- Using Migration Wizard, I migrate the original user from the clone copy I made earlier of the SSD
- Migration wizard finished fine
- Rebooted SL to login to the other "migrated" user account
Safe-boot only:
- The machine wouldn't boot normally after migrating the user account
- After the grey screen, it shows the expected blue OS X screen for a second, but then shows a distorted image, and I can move the mouse pointer, nothing else happens though.
- Safe mode works fine (so does Single user)
- When trying to track down the problem with Verbose mode, it doesn't let me see what's wrong, because it switches to the OSX UI.
I tested the HD several times through the above steps, and it completes the verification process without any hickups.
I have been googling this issue for a few days now (whenever I get a moment, really) and am stuck at this stage. Searching these forums also haven't lead to a solution.
I seems obvious that some settings from my old system were migrated that are stopping the new MBP from booting.
The fact that the screen is distorted makes me think it might have something to do with the new high-res screen this MBP has!
Software installed on migrated user:
- Adobe CS4
- Parallels Desktop 5
- iWork
- iLife
- a variety of other software, but the above are the most notable
Thanks in advance for your help and insights!
Hope someone can help me with this issue, because I don't like the idea of having to reinstall all Apps on a clean OS

was only after migrating the old account that things went wrong.
Hmm...that's the last place I'd expect an issue?
EDIT: Wait... if you didn't migrate the first time you booted up the system in Setup Assistant than you may have created another Home folder. Check your /Users in Safe Mode.
Thought twice about cracking open a new MBP, but spent quite a bit of cash fitting SSDs in 2 desktops and a laptop 6 months ago, so didn't feel like coughing up another 600 USD again.
Yes, that what I thought and in concept it's a good idea but I'm actually quite hardware challenged myself, so wouldn't even dream of it
Again, there's a lot of savvy hardware folks here, so I hope you get some concrete help.

T510: Can't load Windows 7, Keeps rebooting only works in safe mode

Trying to get my T510 up and running after my W520 went DOA after a bios update. When i power on the laptop it tries to load Windows 7 then goes into a rebooting loop. I can get into safe mode with networking just fine without issues, so i figured it was a display driver problem. In safe mode I unstalled the Nvidia drivers and tried to reboot but still got the same issue. I went into the BIOS to see if I could disable optimus and use just the intel GPU, but I don't even see a setting for disabling it or reference to the NVidia GPU at all. I'm positive it was there before.
I've swapped hard drives and memory modules out. Even tried to do a fresh install of Windows and it still won't load. I'm out of ideas. Any help would be greatly appreciated. Thanks.

Try and applied the machine updated in Safe mode. It usually works. If your install is from MS DVD then be sure all the foundation software is installed. Chipset tool especially and build from there.
You could also run the memory diagnostic after booting from the MS Windows 7 DVD. Eliminate a bad memory module. (If you have two) take the first on out and move the second one into the first slot. See if its stable, remove and insert the other SODIM into the first slot. Why, normal mode is very intense on RAM and also address a lot more memory.

[URGENT] Torch 9850 wont turn on after updating, gets stuck at 60 - 70% went booting up, and if I try to start it in safe mode it gets to 60% and shuts off.

Hello everyone how are you? Im having a problem as you can see with my 9850. One day i woke up and it wouldn't turn on, did battery pulls and still nothing. It was fully charged too. I connected it to the computer and updated it. During update error messages came up saying it couldnt connect to app loader. Eventually updating was complete. It booted up and stopped at about 60%-70% and stayed there for hours until it shut off by itself (probably the battery died). I did a batt pull and the same thing happened. i wiped the device with bbsak, reloaded the OS, and got the same result. Even the whole app loader error message came up again. Went to the forums to find a solution and tried opening in safe mode. Everytime i try to open in safe mode the phone shuts off and reboots. So now i have run out of options. Can someone please help me get my phone back up and running please. Id really appreciate it.

You might try again, wiping with BBSAK and again loading the OS fresh.

Kernel Panic at boot but works in safe mode

I am getting a Kernel Panic at boot on the grey screen If I boot safe mode it works fine.
Whats the procedure to find whats cause the problem? Is there a log file I should look at or what is the best way to figure this out

Also check /System/Library/StartupItems & /Library/StartupItems (neither of which is in your home folder) -- any items in them are suspect since none are installed as part of a standard installation of the OS.

Can anyone ID this problem? Finder icon started bouncing, unresponsive, now Safe Mode reboot stops 1/3 in and shuts down iMac. Virus?

This started yesterday. I switch on the computer, go into my User account and the Finder icon was bouncing in the deck while a window flashed on about Restoring Windows though you could never click on it because...it kept flashing. The folders on my desktop disappeared so I went into a secondary user account and opened it to find a virus scan. That user account had no issue with the bouncing Finder icon. I downloaded ClamXav and ran it but that being a rarely used user account, it found nothing infected. I went back in in Safe Mode and was able to see my invisible files but the Finder being unresponsive, I could basically only look at them. Also, I couldn't activate ClamXav after downloading it in that user account. All it did was allow me to see my files.
This morning, while I switched on the computer the Safe Mode came on without me holding down the Shift key. Sadly, it didn't get past the third of the little progress bar before shutting down the computer. This happened trying to open either user accounts. I'm shut out. I'm so shocked this happened. I called the ISP and he said everything was normal at his end, naturally in spite of a lot of freezing and not allowing more than one device on wifi at a time. This is an upgraded Internet service after moving to a new place. Otherwise for the few moments it lights up to show me the two users at log in, nothing is visually wrong.
If this has ever happened to anyone, please enlighten me. I've called a Mac repair shop and expect to bring my iMac in. It's barely two years old. : (

When posting in Apple Communties/Forums/Message Boards.......It would help us to know which iMac model you have, which OS & version you're using, how much RAM, etc. You can have this info displayed on the bottom of every post by completing your system profile and filling in the information asked for.

Superfish was bundled with the latest Firefox upgrade-how do I get rid of it since it d/n appear as an add-on (although it can be disabled just as an add-on would be when in safe mode)?

Superfish appears on most of the shopping sites I use since I upgraded to the latest version of Firefox. I have tried to investigate ways to remove it (since it is behaving like malware even after getting past Norton) but I am unable to follow the standard instruction of disabling the add-on. It does not appear on my list of add-ons and extensions. Any help would be greatly appreciated. The only way I can avoid this annoyance is to run Firefox in safe mode, not optimal for me.

Hi Walter,
Hopefully this blog explains it a little better

Can't create bookmarks. New install, have disabled all extensions, tried safe mode and reset to defaults. No help from any of these actions.

Hello.
Problem statement is very simple: Firefox will not create bookmarks.
New installation with Mint 17. New PC build with Asus A58M-A/USB3 mother board, AMD A4 6300 processor, 4 gig memory stick.
All of the Mint and Firefox packages are up to date.
A new profile was created for testing, Firefox has been started in safe mode, purged and re-installed and reset to defaults. None of these actions have helped.

Can't Boot Macbook Pro from CD, Tried 3 known Working Discs, Can boot Ubuntu

I am trying to boot my macbook pro with the Snow Leopard CDROM. Regardless of how I attempt to boot I get the white screen with the Apple logo and nothing else. I've let it sit there for 45 minutes at one point. There is no apparent disc activity at this point.
I've tried holding C while booting. I've trying runing the Installer while booted of the internal disk, selecting Utilities, and then Restart and same problem.
I've tried 3 known working copies of Snow Leopard our helpdesk uses on a daily bases. None of them have any scratches and are quickly mounted and easily redeable in my mac when booted from internal disk.
I can boot fine from an Ubuntu 11 64-bit CDROM.
I've tried reseting the PRAM multiple times. I've tried booting into firmware mode but that doesn't seem to work. (cmd-option-O-F)
Very frustrating.

Is this the gray disc that came with the machine, or is it a retail disc? If it's retail, did the machine come with SL installed? If so, you can't use a retail disc.

MF Crashes on startup, but works in safe-mode and for a few minutes after making a new user, can anyone help?

After troubleshooting for a few hours, I still cannot find a proper solution. Effectively, I learned that if I create a new profile user, with this command in windows Run: "C:\Program Files\Mozilla Firefox\firefox.exe" -p , I can open the user profile menu manually, and create/delete a new/not-new user, and upon creating and using a new one, it works fine. For a couple of times opening the browser, anyway, in which it results in the same problem as before. I took a list and compared the old files to a brand new users files, and did find some differences. Take these into effect,
The compatability and extensions .ini files were differed by 3 kb , with a new user being 1, and the old user being 4.
The Local Store .rdf file differed from 2 for a new user, to 4 for an old user.
The Mime Types .rdf file differed from 3 for a new user to 4 for an old user.
Plugin Reg(istry?) .dat differed from 17 new to 20 old.
Search.json differed from 13 new to 16 old.
Search Metadata.json differed from 1 new to 4 old.
URL Classifier Key 3.txt differed from 1 new to 4 old.
Web App Store.sqlite differed from 96 new to 128 old.
(All units are KB)
Seeing as a few articles relating to the problem are "no longer maintained" and the solutions work only temporarily, I came here hoping to fix this little issue. Thank you, and good luck in advance.
-Av
Note; the first crash ID is for the new user that crashed, the last is for an old user.

I see.. I have heard rumors of this, but it did not occur to me that this would literally crash upon startup. Thank you for the help, Edmeister. Will check as "solved it" if it works. Thanks again!

My I mac 27 late 2009 will not start up I get to the grey screen with the mouse cursor but it stays that way. if I press shift during the boot i works into safe mode. any idea?

It gets to the grey screen and the mouse point sometime show up but noting more.
when I press shift it does load up into safe mode
i re-installed lion no changes

Can I ssh to a Mac that's booted into Safe Mode?

I'm needing to ssh to a Mac that's been booted into Safe Mode (I'm already able to ssh to it in normal boot mode, and I know how to boot it into Safe Mode from the command line, i.e. sudo nvram boot-args="-x", then sudo reboot).
I can't just test this for myself, as it has to work first time, otherwise I'll be locked out of the remote Mac. If ssh would still work in Safe Mode, the plan is to then ssh to it and issue the command to set it back to normal boot mode (with sudo nvram boot-args="") and then reboot... job done.
Ideally, but not too important, I could VNC to it in Safe Mode instead, but ssh would do fine.
Does anyone know (for sure!) please?
In case anyone wondered, I'm wanting to do the Safe Boot because I'm told it can cure an issue with Adobe CS apps freaking out and locking up, crashing etc. I want to try this over the w/e, and have no physical access to the Mac. I've already set it to power on later (via pmset) - something I do routinely.
I thought an answer to this would be easy to find, but after Googling I've drawn a blank. Can't find it in any Apple docs either.
Thanks in advance!

If this was already covered somewhere else, I
apologize. I did some browsing for this topic but had
no luck finding anything...
Anyhoo, I'm trying to log in to my wife's B&W G3
(running Jaguar) from my G4 (running 10.4.2) using
secure shell but she doesn't have a password set up
on her computer. When I enter the ssh command in
Terminal, it asks for a password — I don't enter
anything and just hit the Return key. It returns with
a massage saying "Permission denied, please try
again." What can I do to log in w/o setting up her
machine with a password first?
If you want to use SSH securily I would suggest you disable password authenticaiton altogher. If you setup public key authentication it is more secure and better than using passwords anyway.

Solaris 10 11/06 can't boot if I remove DVDROM

dear all...
I try to install Solaris 10 x86 11/06 on HP Proliant DL140 with SATA HDD but no DVDROM...
I borrow my PC DVDROM and install to my HDD...eveything run fine
but when I remove my DVDROM, solaris can't boot the OS...
may be because configuration change...
Cause when I'm install solaris with DVDROM install the disk became c1d0
but with no DVDROM became c0d0...
I try gooling move solaris disk boot do some stuff like rm /dev/dsk/c* etc... devfsadm...edit /etc/vfstab
in failsafe mode, but still can't boot...
but everything run normal when I install the DVDROM?
how can I boot the solaris without DVDROM install...(change bootdisk from c1d0 toc0d0)
thank you...

Same problem. Left it sitting there for 3 hours
hoping it'd wake up.
Using burned DVD ISO image. Tried it with 2 seperate
burns. Works on another machine (which BTW can't find
any drives - possibly because of the 500G onboard
RAID-0 SATA configuration) and with a burned CD image
as well just to see if there wasn't a problem with
the DVD boot ..

Still waiting :c/Yea, this thing is useless for me. I ordered the free media kit from Sun so I can have an authentic DVD and it never arrived - so I installed Windows XP Professional Edition back on the system.
I even upgraded the RAM from 256 to 512 because I thought it was a memory issue (not enough RAM to start the installation).
Pretty useless until it actually supports more hardware - it's like trying to run MacOSX on a non-Apple system.
I'll check back in a couple years and see if it's usable, cause it isn't ATM. That is quite a shame, too.

Can the Boot Camp Drivers be installed independently of each other?

I am having major issues with Boot Camp 3.1. It seems to put the windows 7 side of my mac to sleep immediately upon boot up. I have isolated the problem to Boot Camp and I was wondering if I could remove individual drivers to isolate which driver is causing the problem.
thanks,
C

Hi,
the Driver Setup program cannot do this so you would have to do this yourself "by hand".
For that copy the full content (files and folders) of the BootCamp Driver package from your OSX Install DVD to a folder on your Windows partition.
I prefer something like "c:\download" for this.
After that go through the appropriate Folders for the hardware components in your Mac and install each driver by hand.
Have you already tried the Safe-Boot options of WIndows 7 as described here http://windows.microsoft.com/en-US/windows7/Advanced-startup-options-including-s afe-mode especially the Safe Mode and the Enable Boot Logging to determine if it is indeed a Driver problem or maybe some kind of startup item ?

How can I perform an "in-place upgrade" on an unbootable Windows 7 machine or at least rebuild Safe Mode?

Some strange glitch has erased every single unlocked & unprotected file on my C: drive. It wasn't a virus because I checked autorun records and running processes using the respective Sysinternals utilities and didn't find anything suspicious.
I restored all data except for some system files and files that had "too long" of a path using shadow copies, which luckily for me were just a few hours old. Then, I decided to reboot into Recovery Environment and run System Restore from there. For even
more strange reason, the available restore points in RE were dated November 2010 (it's May 2012 right now) and the recent save dates are nowhere to be found.
To make matters worse, SFC doesn't work and Safe Mode shows BSOD after loading CLASSPNP.SYS.
Error messages so far:
RE's startup repair tool: System files integrity check and repair error code 0x2
SFC: Windows Resource Protection could not perform the requested operation
BSOD: 0x7B (0xFFFFF880009A9928, 0XFFFFFFFFC0000034, 0x0, 0x0), but the HDD is perfectly fine - it's a dual-boot machine
CBS.log: Failed to get CSI store. [HRESULT = 0x80073712 - ERROR_SXS_COMPONENT_STORE_CORRUPT]
What I need is a way to perform either an in-place upgrade without booting into Windows, or a way to fix the SXS Component Store, or rebuild the Safe Mode so that I could initiate upgrade install from there. A clean install isn't an option because I don't
have the luxury of time to run through the reboot cycles when re-installing and updating other software (I'm using Windows 8 CP for now as my work tools are mostly in the cloud).

It is not possible to do a repair install of a system unless you can boot to the system.
Have you checked the hard drive for problems? - download the manufacturer's test utility, create the disk, and run the extended checks.
