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.
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.
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 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.
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.
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.
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]
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.
Been having probs w Mac Pro w Lion seeming to hang on shutdown/restart. Have 'reopen windows' unchecked in prefs.

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?
My Mac Pro main boot drive us encrypted. I booted into recovery mode the other day & it wouldn't let me boot back o my main drive. Now upon start up I can't enter either recovery mode nor safe mode nor chose the main drive to boot from. I'm absolutely stymied in what to do.
I have been unable to restart me computer after a software update (White screen/apple logo/spinning wheel continuously). I have tried to start up in safe mode (holding down shift key) but it hasn't worked.
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".
my computer wont run in regular mode. The problem occurred when I was changing my resolution and I pressed the wrong one. The screen went blank so I restarted, then the screen turned black after the apple logo. Now I can only run in safe boot. Is there any way to change the res. for the regular boot in the safe boo mode?
I have a week 50 machine with the firmware update that flickers only when Snow Leopard is in 32 bit mode. If I boot into 64 bit mode (holding 6 & 4 as the machine boots) it does not flicker. Can anyone else confirm this?
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.
i need help cause my brother logged in to the guest mode and since then it goes to guest mode automatically with out giving me the chance to log in the only way i can get back in to my account i have to hold the shift key down at boot, yet when i let the mac boot up normal way it goes straight to that safari web browser.
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?
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.
