Software :: Won't Work / G5 Boots Only In Safe Mode
Nov 23, 2009
I have a number of macs one being a G5 1.8 x 2 that has been running 10.3.9 for quite some time with no problems whatsoever. Decided to upgrade to keep in line with other macs but first just to 10.4. Machine only boots in safe boot mode. If regular boot, get message that I need to restart. Restart message reappears and often fans race. May have kernell panic but did hardware test, disk first aid and all hardware checks out fine. Finally downgraded back to 10.3 and machine works fine. Did total clean install with 10.4 again and same results. Is there a firmware I need to upgrade, I can't find one. I have been working with macs exclusively since 1989 (never user a "PC") but I'm perplexed.

Soda was spilled on the side of the notebook. It was never powered on. I opened up the notebook and cleaned all the components. Now the MBP only boots into safe mode.

Today, my Macbook Pro 15" started to automatically boot up in Safe Boot / Safe Mode. So every time I boot up, I have to wait 5-10 minutes and stuff. It's not normal.
I tried: Restarting, Shutting down and booting.
Resetting PRAM, NVRAM
Verifying and repairing Hard Disk in Disk Utility (it fails). Tried in Mac OS and OS Installation Disk. etc. I got this computer 6 days ago, and there is already this problem. Is there a way without reinstalling the OS? I have Windows installed on it for gaming, but I don't see anything else that could be causing the problem.

Upon start up, I hear the chime, see the grey Apple load screen, but then after it just reaches the blue screen and stops. Cannot reach login screen, unless in safe mode.Steps I've tried:
-Reinstall tiger (erase and install)
-Replace CMOS battery (time now works correctly)
-Run Apple Hardware Test (no errors)

I have a feeling I need a new motherboard to replace my graphics chip. I was playing World of Warcraft last night when the entire computer froze and a pink grid came over the computer. Could not force quit. About 10 seconds later, Kernel Panic screen and I have to hard reboot. Every time I reboot the pink grid is still there and it kernel panics, does not get past the spinning Apple logo. I was able to hold down shift and get it to safe mode, and was able to back up my files that way. I also ran the Apple hardware test, but it said no problems found. I am typing to you now in safe mode on this pink screen.

Tried everything from archive and install (wouldn't read disk2 until the 9th try and ended up with 9 system folders). Then tried an Erase and Install. Still it refuses to boot. Get's hung up at the blue screen. Will only boot in safe mode. Now for the last few days even the startup chime is missing. Tried PRAM and NVRAM resets. no help. Won't boot from DiskWarrior boot disk either. Just hangs

I have a 15" mbp with 10.6 Intel core duo, 4gb ram with a boot camp and ubuntu partition through parallels. The other day I was installing xcode from apple's website, which failed 3 times after downloading saying the package couldn't be expanded. I left my computer for a while and came back where i then had to log in again. it rejected my password numerous time (i'm positive it was correct). when i restarted my computer i got a kernal panic screen when the apple logo came up. it told me to restart the computer which i did. didn't work. i restarted with the osx cd to use the disk utility. when it checked the drive it found a bunch of errors, which i then tried to correct. it went for a couple minutes then told me they couldn't be fixed and i should try to back up my data and reinstall osx. i don't know how to back up my hard drive when i can't log into my account. i've tried to boot in target disk mode and copy some files that way, but the only disk the other computer sees is my windows partition- no mac partition.
i've also tried these, none of these have worked: restarting in safe mode resetting the ram and pram booting with different sticks of ram all result in a kernal panic.
my windows partition still works fine though (as much as i hate to say it) the only things I really care about on my computer are my files from school and my itunes library. is there any way i can get these files off my computer?

I have a 21.5 inch iMac and am running Snow Leopard. I am familiar with Safe Mode and I understand that it does a disk check and repair and also does some cache clearing during a startup process that allows the user to startup into a system where certain kernel extensions, etc, are disabled to allow for trouble shooting. Then the user can do a restart and end up back in normal mode.
My question is whether starting up into Safe Mode could prove beneficial as some sort of routine maintenance?

Leopoard 10.5.2 - Quad Core Mac Pro.
I'm trying to start up in safe mode, per a recommendation from Objective Development, for a Little Snitch upgrade. I'm following these steps perfectly, and I see no indication that I'm running in safe mode. Of course, I've never seen safe mode, so I'm not sure what it looks like, but I'm guessing I ain't in it because I never see the "Safe boot at the login window".
Quote:
To start up into Safe Mode, do this:
1. Be sure the computer is shut down.
2. Press the power button.
3. Immediately after you hear the startup tone, press and hold the Shift key (the Shift key should be held as soon as possible after the startup tone but not before).
4. Release the Shift key when you see the gray Apple and the spinning gear. Please be patient, booting in Safe Mode may take some while.
During the startup you will see "Safe Boot" on the login window, which appears even if you normally log in automatically.

I started (because I wanted to) my MBA into safe mode. Just hadn't tried it before. It took, what seemed, an inordinate amount of time to boot.
I pressed the shift ket at the BONG and released at the spinning gear screen. Is this normal? Does OS X perform disc read/write, verification, cache handling, etc. that causes the lengthy boot.

on pc, when they get software related issues, i press F8 for Safe Mode and im in 9/10 times. on Mac, I've never gotten Safe Mode to work when there's a problem.
say i DID get into safe mode, whereas i couldn't get in regularly. what more could I do that I couldn't do from disk than Repair permissions?
I guess what i'm getting at is WHAT IS SAFE MODE GOOD FOR?

I have a G4 533 and up till 3 weeks ago it worked wonderful for a mail server. I have 1.5gb and a 300gb hard drive which has been working wonderful with no conflicts. When restarting after a software update, I noticed on the start up screen that it restarted in "safe mode". I checked for a stuck shift key and of course they were just fine. I thought it might be a heat problem because the next day I started it back up and it started normally so I ran disk utility to make sure. The next time I started, no matter if it was cool or warm, it went straight to "safe mode" just for grins, I backed up all my information onto an external drive and attempted to re-install the 10.4 disk and it went straight to the black "kernel panic" screen. "OK" I said, so I took out the 300gb hard drive all together, installed a freshly "zeroed out" 120gb hard drive that I had and then tried to start it up and it went straight back to the "kernel panic" screen. Next, I not only unplugged the cord but also took out the battery which only then would it start up alright. So now that is the only way that I can get the machine to start up in anything other than "safe mode". At this point, it is a pain in the ass but so far it is working. Does anyone have any idea what I have overlooked or what is wrong? I would really like to use the box but it is just a pain in the a$$ to do this.

I wonder, if there is a possibility to tell OS X to always boot in Safe Mode. Because often, after a power failure, the mac mini boots automatically how he should, but then he crashes while booting.

This iBook G4 will not boot. I can boot it into safe mode, but that is about it. I have tried resetting the PRAM, to no avail. It cannot even boot off of an OSX disc. When I try to boot it normally, it just shows the Apple symbol, but no progress wheel thing spinning. When I try to boot it normally, it appears as if the hard drive is not being read from/written to, because it is dead silent, but when I boot into safe mode, you can hear the HDD noise. When I booted into safe mode, I checked the HDD's SMART status, and it says "Verified," so I do not think that the HDD is at fault. However, it still has its original HDD from 2004.

Samsung TL350
OS X 10.5.8, MacBook
I cannot get my camera to be recognized by my computer when I plug it in and the computer is normally booted.
* If plug the camera into my MacBook, Image Capture and iPhoto will not recognize it.
* If I plug the SD card into my computer with a card reader, the card will be read just fine.
* The camera works on two other MacBook Pros
* The camera will be found on my MacBook if I boot into Safe Mode
* The camera is found in System Profiler when the computer is normally booted, however, the information provided is limited.
* The camera is found in System Profiler when the computer is Safe Booted, and the camera shows the full amount of information about the camera
When I open the system log and then plug the camera in, I receive the following:
Sep 6 11:46:14 JoAlDe kernel[0]: USBF: 958.769 AppleUSBEHCI0x27b8800::Found a transaction which hasn't moved in 5 seconds on bus 0xfd, timing out! (Addr: 3, EP: 0)
Sep 6 11:46:19 JoAlDe kernel[0]: USBF: 963.770 AppleUSBEHCI0x27b8800::Found a transaction past the completion deadline on bus 0xfd, timing out! (Addr: 3, EP: 1)
From what I understand, this means that the computer is unable to see that the camera is a Mass Storage Device, thus it times out and is unable to boot it as such.
So I set up my system with the USB Prober and the associated logging file.
I ran the USB Prober on level 7 while I connected the camera.
I know zilch about reading and comprehending any of the results except this snippet really stuck out to me:
It occurred twice more:
3635.575 [5] Finding driver for interface #0 of Samsung Digital Camera, matching personality using com.apple.iokit.IOUSBUserClient, score: 104999, wildCard = 5
3635.575 [6] Matched: idVendor (8107) idProduct (4152) bcdDevice (256) bConfigurationValue (1) bInterfaceNumber (0)
3635.575 [6] Didn't Match: nothing
Just looking at this particular result, it looks like the computer is unable to identify what exactly USB device is being plugged in.

i splashed some theraflu on the right side of the keyboard approximately 3 days ago. as many had mentioned, i removed the keyboard and carefully removed any liquid residue i could find and kept my computer off for a few days. today i went to figure out the damage and everything seems to work okay in terms of the computer turning on and stuff. the keyboard is still acting up though. the left side of the keyboard works mostly okay, but if i press certain letters, the number along with random number appears. the right side of the keyboard, on the other hand, several keys don't even respond at all. from these "symptoms" do you guys think the only thing that i may have to replace is the keyboard or could these "symptoms" i've described be related to some other damage also? how much does replacing a keyboard usually cost? i'm thinking this isn't going to be covered by my warranty. lastly, i've noticed that when i do turn the computer on, it automatically starts in safe-mode.

My MBP (2012 or 2013 not sure which!) is having an issue. When I try to login, my password is accepted and then a progress bar appears. After a quarter load, my mac turns off. Unfortunately safe mode (holding shift) does not work. I have tried smc and pvram resets and repairing through disk utility. None of this has worked...
I'm running yosemite. The last thing I did before logging off is installing divx web player.

I just go a new Macbook Pro 13' from my school (my school made it mandatory to get a mac this year) and I was installing some of my applications. Then I got the "You need to restart your computer" message. I restarted, and all i got was a blue screen with my pointer. Then after a while it says the same restart message. Also I have tried booting from the Snow Leopard Disk, but I get the same message before the actual SL installer comes up. I have been able to get the Macbook to boot in safe mode and I repaired permissions and the disk, however that does not seem to help. I have also reset the PRAM and that did nothing. I am running out of ideas... how can I fix this? I am using 10.6.4.

I recently bought a 15" powerbook and when you turn it on it shows the apple logo (grey screen) then when booting into Tiger, it shows a black screen with white text detailing drivers and things that are being loaded. Is there any way of switching off this black screen booting? I have even tried swapping harddrives and reinstalling Tiger but it still does it, so im guessing it has nothing to do with the Tiger installation / Harddisk.
