Safe Boot Mode Freeze and Mavericks and Core Storage

I was having a problem booting into Safe Mode on a new iMac. It froze and restarted continuously.
Eventually I was told by engineering (after the Senior Tech) that...
"It’s expected behavior from any disc formatted with core storage and that includes discs encrypted with File Vault, a Fusion drive, or any internal disc larger than 2.2 Terabytes."
They also went on to say...
"They are investigating and improving the performance for future releases of OSX Mavericks."
FYI to those reported to have these problems. Don't waste time with it...it won't work. I reinstalled a clean OS, the Apple Repair depot installed a clean OS and when I got it back, I reinstalled it again.
It still doesn't work.
No reported fixes on the horizon at this time.
FYI

Not every iMac will have this problem, only the ones with the hardware as specified.
I think you should look around a little more on the net and you will find that there are others who have had this problem. Apple Tech also noted that they were aware of the problem.
One mitigating factor is that many Mac users have no idea what Safe Mode is anyway so they'd never notice it. My own iMac runs just fine, no probs and I calculated that I must had this problem for over 6 months until I stumbled on it. If I hadn't I'd still be using it and it might have gotten fixed by an update, in which case, I would have never known that I even had it to begin with. If you own an iMac that has not been formatted for disk spanning, then you won't have this problem either. All my other Macs run Mavericks and I have no problem with any of them.
I don't believe that there are that many people out there who actually own iMacs with 3 TB drives combined with a Fusion drive, sorry. We'll have to agree to disagree here. There are multiple factors at work here.

The keyboard for my iMac 9, got wet and is not working correctly. Delete ,return, and some other keys not functioning. In all caps including numerals. I've left it to dry for a few days but still will not work. Computer now in Safe boot mode and I can't login due to all caps and numbers being symbols. Is there anything I can do?

Buy a replacement keyboard. They're only $50-65 USD.

Hi it's puzzled of Evesham....I didn't ask the question but have experienced exactly the same. I switched the computer on and it went straight to safe mode

Can't Safe Boot with 10.6.2 and GTX 285

Can't safe boot with 10.6.2 and NVIDIA GTX 285 (2009 Mac Pro).
What the heck am I supposed to do, take out the graphics card every time I want to safe boot?!
Suggestions please!

No, I think what it is, is that the GTX 285 drivers somehow are being treated as 3rd party extensions not to be loaded on a safe boot, but the problem is that without those drivers, even if I switch my monitor over to my GT 120 card, it still won't boot. Ugh.
I am considering reinstalling 10.6 over on top of my current system, then putting the 10.6.2 on top of that. If I do this, do I risk losing any preferences or having to reinstall any 3rd-party software? At this point, I'll happily reinstall whatever it takes... I just didn't want to have to do a clean system where I have to track down every single bookmark file and saved preference for my main apps, but it could be this is now starting to take more time than it simply would have to do that from the get-go. Sigh.

G5 only starts up in Safe Boot mode

We have an older model G5 Dual (no Intel Core) at the office that we tried to install CS3 on. I told them that first we would need to upgrade from 10.3.8 to 10.4.10 -- which they did, and then installed CS3.
But they did it without running the disk utility repair permissions after the OS software installation, as I have routinely done with my Mac Mini at home, after the horror I experienced with the 10.4.9 upgrade.
For a couple of days, the computer ran fine, but I noticed an increase in the fan spinning up yesterday afternoon, then quirky keyboard things -- like I'd select an item with point and click, and it would highlight everything else near it, I'd go to quit an application and it would ask if I wanted to quit all applications. After backing up my current InDesign work files on a flash drive (but not the whole darn art folder), I rebooted and it came up in Safe Boot mode 6 times without holding any key down.
Attempts to boot from disk have failed, even with holding down the "C" key. It's also not allowing us to type out full passwords at the log-in screen... you start typing and after you hit four digits, it clears, then only allows two digits. Weird, huh?
Any suggestions on how we can:
1.) Force boot from disk, and,
2.) Hopefully fix with disk utility whatever wonkiness is occuring?
Thanks

Hi,
Not sure if you are still in the same position or not..
Do me a favor and switch keyboards and see what the results are.
(I have dealt with a few diff variations of this problem, and each had a seperate solution.)

My macbook pro ended up in safe boot mode randomly twice in a row...how do i fix this permanently??!

And I think this issue is coming from a few different problems I've had with my MacBook Pro on lion...one major thing was probably the fact that I changed from Lion to Mountain Lion...and then changed right back (I think I did back up my stuff first), but somehow it didn't agree with my computer. Also I've been wearing it out a lot by throwing it with the case into my car frequently...maybe a bit much, idk...also though I have a lot of trouble keeping up with the numerous files that build up on my desktop and don't know where to begin. Let's just say my computer has pretty much had it, although for months it's been functioning normally.
...oh yeah and did I mention I had to get a brand new hard drive, with that not really making a difference as to how bad I, um, throw my computer around (it's not as bad as you think but to be candid, blech). I did bang my computer at one point in a rage attack and made sure no one really knew when I took it to get it fixed? TMI...that's what I deserve....so.
I did try this web link the second time in a row this happened which was about an hour or so that I managed to, uh, kind of fix it with the bottom advice on the page:
http://applehelpwriter.com/2012/06/24/mac-keeps-starting-in-safe-mode/
(sorry I couldn't get this to click)
Anyways at the bottom of this help article you will notice the very end of PRAM reset directions where you hear the start up chime two times. That did not happen, but somehow out of nowhere the computer stopped the safe boot mode routine and the progress bar didn't show up as I continued to hold down the given keys. I really don't know where my luck came from there...and I also found an article that fixed my computer the first time and I cringe to say that it came from a person on Apple Discussions complaining about something similar that one of my friends helped me google. Planning to actually bookmark the applehelpwriter article in case I just happen to need it but i'm pretty sure someone will be on here with an answer at some point.
SO....I did get my comp fixed twice now, but I hope that somebody will go back and read the beginning of my question explanation to see if I'm doing something that may be overwhelming my computer. If this safe boot thing happened to me instead of me testing the computer myself AND MORE THANA ONCE yikes...something needs to be done. Take note that the only reason I'm asking the community's advice is that I'm past my computer's contract so if I wanted to I couldn't take my computer to get it fixed and I planned to take one or two more classes in college again to complete my certificate.
Please help, some people must run into this situation at some point, either way if they ask or don't I'm sure they're lucky to get it fixed somewhere.

Only if your home/renters insurance doesn't cover such damage without raising your rates/dropping you. Ask first of them if it is worthwhile the claim once you get an estimate for repair. These repair places are pretty good:

IMac keep ejecting my 2TB external HDD but in safe boot mode it is totally fine. How to resolve the problem?

Hi,
I have WD 2 TB external HDD. It has two partitions, one I use for my time machiine backup and one for my personal files and documents. Recently the iMac keeps ejecting the external HDD as soon as it gets connected to the iMac. I tried to reboot the computer in safe boot mode (by holding down the shift key at startup) and found out that problem is not there anymore. I can access my external HDD there and it never ejects the HDD.
It seems like the HDD is fine, the problem is with the iMac. Can anybody please give any solution to this problem?
Thanks!

Thanks Allan for your reply!
It makes sence that there must be some log in /start up item which is causing this problem. I went System Preference>Users & Groups> Login items> disabled all the items there to make sure, and restarted the computer but the problem is still there
Is there any other way to stop/configure the log in items?
Thanks again!

White Macbook 13" will not boot - Stuck in Safe Boot mode

In a nutshell --
macbook will not boot. Originally it was stuck on the gray screen with spinning wheel. Here is the course of action taken thus far (in order)
1. Reset SMC -- removed battery, pushed power button for 5-1 seconds. Rrestsarted. Nothing. Still with the gray screen etc.
2. Tried to restart in Safe Boot mode. -- Macbook will restart and after 25% on the status bar it hangs up. After a 5 minutes or so it shuts down (I assume form overheating as the fan is running wild.)
3. Wheneve I start it now it tires to go in safe mode so I tired to zap the PRAM (opt/command/p/r) No luck. Tried twice. Once after three chimes. Once after 2 chimes. Still tries to boot in safe mode.
4. Tried Recovery Mode (I am running Mountain Lion). Can boot into recovery mode. Ran disk repair and it said all was fine. Would not allow me to repair permissions but I could verify them. I ran verify. No messages came up at all -- thought this was strange. I also tried to re-install the OS but the first time the only disk available to me was the recovery partition. The second time I went into Recovery mode I saw the regular Hard Drive partition but it was grayed out and locked. Considered restarting to an external USB drive but then did not know what I would do then. Might try this tomorrow.
5. Ran Target disk mode with my iMac. The disk did not mount in the desktop but showed up in disk utility with the HD partition grayed out. Could verify and repair disk but nothing was allowed regarding permissions -- all options grayed out.
6. Restarted with Verbose mode. Ran for 5 - 10 minutes and shut down. Last line I saw was "checking extended attributes file" No error message. Again, maybe it was an overheating issue as the fans were going wild and it was about the same length of tome running as in safe mode when the macbook shut down.
OK. The hard drive is a few moths old. There was nothing strange going on with the hard drive prior to shut down. The only odd thing happening was the dvd drive was begining to make sounds upon restart (from sleep or full restart). Like it was checking/reading a disk in the drive. This was especially odd as the drive has been dead/unusable for a few years. (When you a dvd or cd in it could not read). This dvd drive sound happens even now upon each start up.
I do not want a new motherboard.......or laptop.
Thanks.
Robert

Thanks for the prompt response. Thanks for the adivice. I wish i could get it to go into safe mode. It stops after 5 minutes of trying. I am not sure if it is the hard drive as it will boot into Reocvery Mode -- meaning it will let me access the 650 MB parititon Lion has set aside - so that part of the disk is working.
I am headed to the Geniusues soon.

I don't think Mac OS X Lion is entering Safe Boot mode

Hi Everyone,
I always do a safe boot when troubleshooting since my first MacBook with Leopard and after installing Lion in a new MacBook Pro, I don't think I'm entering safe boot mode. I mean, I press the shift key at boot time like I've done countless times before but now I think my MacBook Pro is not booting safe.
Namely: I don't see the words "Safe Boot" on the login screen, it doesn't take longer and the pinwheel is not replaced by a progress bar when booting.
Can anyone please tell me what's going on?
Thanks in advance!

When I tried to run the Apple Hardware Test and couldn't start it with the "D" key, even though the "Alt" key and "Cmd+R" boot options did work, I started getting more suspicious.
I reset the PRAM and that fixed my issue.
For the record, the words "Safe Boot" on the login screen did not appear, but the progress bar instead of the pinwheel did.

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.

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

IMac powers down while starting in safe boot mode

My 2014 21" iMac powers itself down after about 10 seconds while trying to startup in safe boot mode. I'm not even sure why it is trying to start in safe boot mode. I shut it down after a power outage while plugged into an APS UPS. I'm guessing that since I interrupted the auto shutdown it is restarting in safe boot mode. Either way, I get a grey screen with a big apple and a progress bar. The progress bar gets to about a tenth full and the power just shuts off.
I've tried starting up while holding the alt key to select the Macintosh HD. The same thing happens.
I'm not particularly tech savvy. Any ideas are appreciated.

Thank you for the clarification and link. I ran the disk utility on Macintosh HD and it said it can't repair the disk, and that I need to reformat and restore. It has an invalid node structure. All of this happened just because I shut it down presumable while it was already trying to shut itself down after talking to the UPS?
At least I use Time Machine.
Thank you again.

My mac book air keeps starting in safe boot mode. I cant enter my password as it is caps lock so i cant access my computer. Please can someone please help me start back in normal mode? Thank you

MY Macbook air keeps starting in "safe boot" mode, no idea why. I cannot get into the system because this mode makes everything write in capital letters and my password is in lower case. I keep turning it off and on but nothing changes and i cannot access my computer. Please can someone help me? Thank you

I'm not getting a clear picture at all of what problems you're seeing. If you are seeing online accounts have their passwords changed, those accounts are being hacked. Someone may already have access to some account and is using that access to reset passwords on other accounts. Change the password on EVERY online account you have. Be sure to use a strong password, and don't use the same password on more than one site.
If you are seeing changes to your bookmarks and browser history, your Apple ID may be one of the accounts that has been hacked. After changing the password on your Apple ID, you need to lock it down with two-factor authentication:
http://support.apple.com/kb/ht5570
Beyond that, we will need additional details about what specific symptoms you're seeing in order to help further. One thing I can say, though, is that these problems are very unlikely to be due to any kind of malware. See my Mac Malware Guide to learn more on that topic.

ArchiCAD crashing on launch (not in Safe Boot mode)

I upgraded to Snow Leopard yesterday. I backed up my Mac using SuperDuper!, then installed SL.
I am having this issue with Graphisoft ArchiCAD, which up until yesterday worked fine: it crashes a few seconds to a minute into its launch.
If I reboot into Safe Boot mode, ArchiCAD works. Then again, I have some fonts issues with it (basically with some extra greek fonts I have) which I didn't have until the upgrade to Snow Leopard.
Any ideas as to why it works in Safe Boot, but it crashes when my system is booted up normally?
Many thanks as always, people.

If you've already checked with the vendor to assure that your version is the latest and is compatible with Snow Leopard, I'd launch the Console utility and in the log list column navigate to FILES -> ~/Library/Logs -> CrashReporter. Look there for a crash report for ArchiCAD. If you find one, post the details here and someone may be able to spot something that explains the problem.

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.
