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.)

Can only start up in "safe boot"

Yesterday my iMacG5 (Mac OS X Leopard) started making a loud noise (fan) and would not respond to mouse/keyboard, so we shut it off manually. Since then the only way I can start it is in "safe boot" mode by holding down the shift key during start up. Otherwise the Mac logo appears but it doesn't go any farther.
I would like to try to reinstall Leopard.
Do you think this is wise?
Is there anything special I should do when I reinstall?
Do you think it will help?
Will I lose any files by reinstalling Leopard?

Welcome to Apple Discussions:
I don't think reinstalling Leopard will fix anything, it will probably just waste your time.
You should fix the existing system or at least check out what that loud noise was, which a reinstall certainly will not fix.
It may have been the harddrive, or the system may have severely overheated.
You should boot into the Leopard DVD by inserting it and rebooting and holding down the "C" key.
Do not install it, but after the Language screen, on menu, top left, under Utilities, run the disk utility and repair the harddrive and permissions. If you get through that, you can probably reboot the system normally and continue to troubleshoot the problem.

Powerbook only starts up in safe boot after kernal panic

Hi everyone,
Here is my problem, My mom.. lol was working on in mail and she though the powerbook crashed, thus she turned the machine off. When she tried starting up again, and it doesn't start up at all.. but gives an error message asking her to restart the system. Thus I did a little research on the internet.. and tried the varouis methods of trying to get the machine to startup into OS X, but it still keeps asking to restart the machine everytime I startsup. I did manage to get it to boot into safe mode /boot.. and then it works ok besides for the airport card that doesn't work. I've tried reinstalling the Tiger, with the archive and install setup.. but that doesn't work either. I'm probably going to have format and reinstall macosx, but i'd rather not because that would mean a lot of valuable info would be lost.. and, no.. I didn't make a recent back up.. stupid me. So, does anyone no what else I could try besides wiping the harddisk and doing a fresh install of Mac OS X Tiger??????? Please help..
Thank you,
Sebastiaan
Powerbook G4 1.5 12-inch Mac OS X (10.4.6)

Hey Matt,
I just though I'd let you know, and it might be handy for the other PoBo 12" inch users out there, it wasn't a software problem after all. I tried re-installing tiger, got the same you must restart the computer error message. So I tried putting the original software back on the machine, panther. Once again it gave the same error. So I remembered reading somewhere that the airport extreme card could occasionally cause the kernel panic if it became loose. So I tried removing the card and the system starts up perfectly. This also explains why the computer starts up in safe mode and gave the restart error when i tried booting it normally. Thus I reinstalled tiger for 3rd time, which work fine. I re-inserted airport card, and thank god.. no more errors. The only thing i don't understand about the whole deal is that my mom didn't drop the computer or expose it to heavy vibrations, this would explain how the card could become disconnected. In Apple's own hardware test, the airport extreme card was found to be functioning correctly. Odd, if you ask me..
Thanks anyway Matt for your help,
Sebastiaan

E mac only starts up in safe boot

Having accidently pressed a few keys on the keyboard while not paying much attention to what was happening to my computer it just switched itself off!!! (I think it was the F15 button that was pressed!) Now it only starts in safe mode and I can't get many of the applications to work, internet connection to name one. How can i get it to start in normal mode again?
Can anyone shed some light on what I've stupidly done and how can I solve it please?
Thanking you in anticipation
e mac Mac OS X (10.3.8)

wim,
Welcome to the Apple Discussions!
Do you mean the Mac always starts up in Safe Mode, without you pressing the shift key? You could try starting with the keyboard disconnected to see if it starts normally. If that's the case, check that the shift keys on your keyboard aren't stuck. You can jiggle the keys, or carefully pry them up and check for anything gumming the key post contact (keyboard keys pry off coming straight up and are replaced pressing straight down; on long keys such as the spacebar, shift keys, and Enter key, there's a wire spring that needs to be folded into the clips underneath).

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.

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.

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:

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.

Will not start even in safe boot after installing latest camera update

MacBook Pro will not start even in safe boot after installing latest camera update.
I started my machine and did a software update. Only the camera update needed. So installed and when required I pressed restart. It restarted and did install. Then restarted again. I expected to get to the login screen and it turned itself off. Tried three more times. Each time shutting off. I unplugged everything, and pressed start waiting for log in window. No it shutdown before the log in window. I then tried safe mode and that did not work either on three more occasions.

I have managed to resolve some issues. I can now restart the machine via a CD boot. If I do cmd C into something like tech tool pro, then restart from that disks menu it restarts every time.
If I try a safe start it shuts down. If I try a normal start it shuts down. I have managed to repair permissions and that cleared up some start up permissions but with no improvement to the boot problem. The only way to load is via the cmd-C boot option. Any other ideas?

Getting grey screen on booting MacPro 1,1; only able to use Safe Boot

I have a Mac Pro 1,1 Desktop running Lion.
Processor 2 x 2.66 GHz Dual-Core Intel Xeon
Memory 2 GB 667 MHz DDR2 FB-DIMM
Graphics NVIDIA GeForce 7300 GT 256 MB
Software Mac OS X Lion 10.7.5 (11G63)
The issue I'm having is the computer started booting to a grey screen with the spinning wheel and would get stuck there. The only way I was able to boot was Safe Boot. From there I could access files on the hard drive and ran a time machine backup.
After doing some research, I read this could be hard drive failure so I bought a new 3 TB SATA WD hard drive, installed it, formatted with disk utilitiy and installed OS X Lion on the new drive. It booted up fine after the install.
On the next reboot, same grey screen. Now I'm back to only being able to use Safe Boot mode to access the computer.
I have now shut down the computer and removed the old hard drive.
I've tried resetting PRAM and no luck.
I tried to run the apple hardware test but couldn't get it to run no matter what I tried.
Any advice? I'm at a loss. I really love this Mac and don't want to replace it just yet.

I'm finding these entries in system.log.
I'm particularly puzzled by " Load com.apple.driver.AppleSMBusPCI failed.." and similar messages.

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!

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.

G5 only starts up in Safe Boot mode
