-Reinstall tiger (erase and install)
-Replace CMOS battery (time now works correctly)
-Run Apple Hardware Test (no errors)

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.

MacBook Pro :: Won't Work / Automatically Boots To Safe Mode

Sep 3, 2010

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.

OS X :: Kernel Panics On IMac - Boots Only To Safe Mode

Nov 12, 2010

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.

PowerPC :: G4 Boots In Debug Mode?

Oct 13, 2008

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.

PowerPC :: IBook G4 Won't Work To Boot In Safe Mode

Sep 2, 2010

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.

PowerPC :: Won't Work With Keyboard And Ibook Safe Mode

Aug 6, 2006

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.

PowerPC :: 12" PowerBook G4 Not Booting Properly Unless In Safe Mode After Clean Install

Jun 29, 2009

I recently purchased a sort of beat up 1.5GHz 12" PowerBook G4, top of the line, and it arrived today. It boots up normally when the apple appears, then it shows the blue screen and then the mouse turns into a spinning wheel. Also, when I move the cursor, a second cursor from the same spot stays in the top-left corner. The PowerBook will only work normally as a headless server (powers on, lid closed), unless booted in safe mode. Another issue is the screen. The seller said there were lines going up and down the screen, but it varies depending on what is displayed on the screen. If the screen is grey or in target-disk mode, they do not appear, but on the 10.5 standard desktop pic, it changes pattern. The lines can be seen here: [URL]

OS X :: Won't Boot In Safe Mood / Only Boots To A Blue Screen

Aug 24, 2010

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.

OS X :: Won't Work With Kernal Panic / No Safe Mode And Target Disk Mode

Jul 6, 2010

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?

MacBook Pro :: Boots Into Sleep Mode

Sep 6, 2009

I have an older style MBP, 2.2, running 10.4.3, and the other day after using it about an hour I put it to sleep. After another hour or so I opened it to use it again. Usually just opening it will wake it from sleep. It didnt so I tried pressing any buttons, no luck. Held the power button til it turned off. Tried to boot up but the screen stayed black and the sleep light went on, but did not pulsate. Tried that a few times with the same result. I also tried hooking up an external monitor, just got "no signal".

OS X :: Can't Boot In Safe Mode?

May 17, 2010

I have a 08 MacBook pro (not unibody) and it is now not booting up. I recently installed a Hitachi 500gb hard drive on the computer and restored through time machine and it worked fine for about 2 weeks and now wont boot and I'm wondering if its probably the hard drive. When I click power the light on the front of the computer will come on and it will sound like it is about to boot then a clicking noise seems to come from the computer and it instantly shuts off. I have gotten it to turn on a couple times since it happened by slamming the comp on the bed then for some reason it will work but as soon as I shut it, it wont turnback on. Any ideas?

Oh and PS the screen never comes on and can't boot in safe mode.

OS X :: Won't Work To Use Safe Mode For Maintenance

Oct 8, 2010

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?

OS X :: Won't Work With Start Up In Safe Mode

Feb 12, 2008

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".


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.

OS X :: Won't Work With Starting In Safe Mode

Jun 11, 2008

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.

OS X :: Applications Only Launch In Safe Mode

Feb 28, 2010

I've been running OSX 10.6.2 without any problem for the last six months until today....Now when I try to run applications (other than Safari which is working slow, but otherwise ok) the application icon will appear in the dock for 2-3 seconds and then disappears without opening the program. I'm not aware that I've added or changed anything that might have triggered this problem. I can however open the applications without any problem if I boot into safe mode. I've tried more than one user profile, disk utilities, resetting PRAM, running Onyx maintenance utilities etc.

Mac Pro :: Won't Work / G4 500 Starts In Safe Mode

Jul 18, 2010

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.

Intel Mac :: It Cannot Start In Safe Mode

Apr 3, 2012

Did a Shift - Command-V and the black screen showing all the startup steps appeared and it all looked good except: AFL Alart Sockwed cant update and INIT Reboot transmit failed. All else looks good. I have tried this 3 times and never go past that point. Then the screen turns off white like it does when it starts normally before the apple appears and the last time the screen went black.

I have tried starting with just the Shift Key and computer starts up but not in safe mode. I have tired starting with the OS X disk and the C key and it will not recognize the disk.I used the #1 disk since the instructions are printed on the disk. Did not work so I tried disk 2 and I get a menu to start the OS or tools. If I click on either one the screen goes white and stays that way.

computer starts fine and provides a login window, and then the desktop screen with screen saver pictures in perfect color. As it goes through starting programs it starts the same programs that is had open when the computer originally crashed. Even when I close them, before it locks up again, and I am forced to restart the same programs open up to the same place. Its like the computer is frozen in one location and will not go beyond that point. Eventually the screen turns white and sometimes black and sometimes gray.

Tech support thought it was the video card, put a new one in but did not fix the problem and then said it was not that but that it was the monitor. I said that did not make sense since the monitor and desktop icons and pictures are beautiful and clear. They then said it was the inverter board on the monitor and Apple only replace the whole thing. I purchased an inverter board and replace it. No change. The tech person said that the computer works find without the monitor connected - I will see if that is correct next. Isn't that a more systimatic testing procedure then trying parts to see if it works? Oh I did do the complete long hardware test. Took about an hour and it passed! Isn't this strange?

MacBook Pro :: What Can I Do In Safe Mode To Fix Boot

Jul 5, 2012

MY MBP is giving me the "NOT" sign on start-up. This comes after initially displaying the Apple logo.This MBP had a new logic board installed by Apple just two weeks ago -- and I know I can take it back but I'd like to fix this myself. I put in a different hard drive after getting the MBP back. It has worked fine for several days. Don't know if these points are relevant, but:

1. First thing I noticed today is that neither of the USB ports would read a flash drive. The port would, however, work mouse and keyboard.

2. The initial non-boot episode took place when I had external hard drives daisy-chained in via Firewire. But, again, this had worked previously, as recent as this morning.This may be significant:

3. The last tasks performed on the MBP were -- for the first time -- to edit video in FCE, make DVD in iDVD, burn IMG file.

4.I have connect this MBP as a target FW drive to another MBP and run "disk verify" and "disk repair" in Disk Utility. It says the drive and permissions are okay.

5. I have booted to a copy of Disk Warrior (latest version, version 4, I believe) and rebuilt directories and files along with verify/repair permissions (everything DW will do). And when re-starting, it still won't boot.

6. When I boot off Snow Leopard DVD and run Disk Utility"verify disk" says "the volume appears to be ok.when I "repair disk" it reports "Volume repair complete." and "Updating boot partitions for the volume as required."

7. I'm able to boot in SAFE MODE, but when I try to restart in normal mode, it won't boot (so nothing was automatically fixed)What can I do in safe mode to address my problem?
