What gets bypassed in Safe Boot?

Does anyone know EXACTLY what gets bypassed in Safe Boot? I'm having trouble with a G5 that will only boot in safe mode. I have tried everything I can think of to resolve my issue, and even have a lengthy post on this forum that went unresolved. I have it narrowed down to something that gets bypassed when doing a safe boot. Any help is greatly appreciated.

Hi there,
In 10.4.x it basically loads "Safe Drivers", (Video is one thing that it could be, disabling Quartz might get around that one), loads only System Fonts, Clears some Caches, Airport is disabled, (this has been a problem a few times with a bad card),and doesn't load 3rd party Login or Startup Items. See...
http://support.apple.com/kb/HT1564
If it only does it in Regular Boot, then it could also possibly be some 3rd party add-on, Check System Preferences>Accounts>Login Items window to see if it or something relevant is listed.
Also look in these if they exist, some are invisible...
/private/var/run/StartupItems
/Library/StartupItems

What a heck is "safe boot"?

Hi guys -- I had to restart my iMac and when it was starting up, the light gray beckground with the gray apple logo was there as usual, however, there was a progress bar below it that hadn't been there before and it took way longer than usual to start up... Once it finished it requested me my password as usual BUT it had a line of red text saying "Safe boot"... I then entered my password as usual, my desktop was there but the volume icon at the top right corner was gone so I restarted it again and all was fine: No "Safe boot" text and the volume icon was there. So what a heck was that all about??

When you boot your Mac while holding the shift key down it loads only a small selection of the various kexts and other process which normally run in the background, together with all fonts other than the handful built into the system. Consequently many of the usual facilities, internet included, don't work. The purpose of this is to enable you to boot the computer when some background process is conflicting or corrupted (usually it's third-party add-ons which do this) so that you can diagnose the problem. It also runs a disk check on start-up, hence the slow start. On the next boot everything is back to normal.

IMac - OS X - Will Not Start / Safe Boot / Boot to CD

Unit:
2007 iMac with OS X ... unknown version
Problem:
Will not boot. Upon pressing power button it attempts to go through startup procedure then grey-screen and error message (You Need to restart your computer. Hold down the power button until it turns off, then press the power button again.)
I have come to understand this is called a "Kernel Panic"
I have been researching this issue all day. I cannot get it to safe boot by pressing the shift key. It does pull a progress bar but ultimately fails and returns to the kernel panic.
I have attempted to start from the CD to attempt utility disk, but I cannot get it to boot from CD. I have held the C key down. I have pressed it repeatedly. I have used it in combination with the alt/control/command keys. All have failed.
If anyone has any idea what might can be done I thank you in advance for your assistance.

You have a hardware issue. Please make an appointment at your local Apple Store or AASP so it can be professionaly diagnosed.

Safe boot, disable

Upon starting my Mac Pro laptop, the machine always defaults to a "safe boot" which requires me to restart the computer. Is there a way to bypass the "safe boot"?

If you have more than one user account, you must be logged in as an administrator to carry out these instructions.
Triple-click anywhere in the line below to select it:
sudo nvram boot-args=""
Copy the selected text to the Clipboard (command-C).
Launch the Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Paste (command-V) into the Terminal window. You'll be prompted for your login password, which won't be displayed when you type it. You may get a one-time warning not to screw up. You don't need to post the warning. If you don’t have a login password, you’ll need to set one before you can run the command. If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator.
Reboot and test.

Stuck in safe boot

I was working on a profeciency test for a job agency and after finishing the test my keyboard was stuck typing everything in caps (caps lock was off and my shift key was not stuck either). I didn't know what to do so I just restarted my computer. Upon restarting the computer automatically booted into "safe boot" and wouldn't let me log in. My password and username was typed in correctly but for some reason it just didn't accept it. Is there a way I can restart my mac and get out of safe boot?
I tried to restart and hold the "shift" key while it was booting and that did nothing. I also tried holding "command + S" and still nothing. It would just keep booting into safe boot and reject my password.

Hello there, Arustemi1.
The following Knowledge Base article explains using Safe Mode:
Mac OS X: Starting up in Safe Mode
http://support.apple.com/kb/HT1455
Of particular note is the following:
To leave Safe Mode, restart the computer normally, without holding any keys during startup.
Thanks for reaching out to Apple Support Communities.

SAFE BOOT/ CANT LOG IN

HI? I WAS NOT ABLE TO LOG IN TO MY MAC TODAY, IT WAS JUST SHOWING IN THE RIGHT CORNER WITH RED LETTERS SAFE BOOT. I HAVE NO IDEA WHY IT IS IN SAFE BOOT, RIGHT NOW ALL I CAN DO IS RESTART IT OR SHUT IT DOWN, CANNOT LOG IN. HOW DO I GET OUT OF SAFE BOOT?

Just take it in and have them fix the key then if you ask them many they can fix your safe boot problem while you have your key fixed

orshikhfromsc,
boot from the Mac OS X Install DVD that originally came in the box with your MacBook Pro (by holding down the C key as it starts up). When the desktop appears, select Disk Utility from the Utilities menu and erase your internal disk. After it’s been erased, reformat it. After it’s been reformatted, exit Disk Utility and reïnstall the version of Mac OS X from that DVD onto your internal disk. After that version of Mac OS X has been reïnstalled, boot from your internal disk and run Software Update to get it up-to-date within that version; that should allow you to redownload and reïnstall Mavericks, if desired. If Mavericks is reïnstalled, run Software Update again to get it up to date.
If you no longer have the two grey installation DVDs, you can purchase a replacement set from either Apple or iFixit.

TS1884 What if the Safe Boot progress bar stops (around the 25%-30% mark)? Any other alternatives I have to get my MAcBook Pro to boot without running into an error?

Hi,
after starting my MacBook Pro I was faced with a grey screen stating that "an error has occurred, you need to restart your computer". I did that multiple times but the same message appeared each time. So I started the Safe Boot. Now the progress bar is stuck at the 25-30% progress mark since 30 min. Any advise on what to do from here?
Any help and advise is much appreciated!

I doubt that shutting it off will do any harm but don't do it too often.
Here is the best advice I can find for you:

Can't get past Log-In window--Safe Boot

I'll try and keep this easy/short: My iMac g-5(first Gen i-sight), when upon startup, the wheel would just spin and then the fans would blow turbo while stuck on the spinning wheel. Was running on Tiger but was able to salvage the h/d and all on it, no damage to it. So we erased all on my iMac and tried booting from disc. No good. Tried starting from another laptop; No good. Then cloned from working Leopard laptop, did basic install and got to the Log-in widow--in Safe Boot mode and cannot get past the Log-in window. I get a dialogue box w/an applications icon that says, " You are unable to log in to the user account "..." at this time. Logging in to the account failed because an error occurred." I hit okay and the dialogue box shakes a frustrating no at me.
What do I do now?
Any ideas? Thanx to all.

Try an Archive and Install now, it will put a fresh copy of the OS but keep, your data and preferences. Cloning from a different system is not a very good idea, you run into the problems you have, and probably other ones as well.
If the A&I doesn't work, you may have to wipe your drive and perform a clean install of Leopard.

What does Safe Boot leave out that is messing things up?

The patient is a 2012 Macbook Pro that replaced a 2009 Macbook but to no real benefit: it's no faster and very frustrating to use. 4 Gb ram, 7200 rpm drive (the old machine swapped so much I added a faster drive to at least speed up that process. Mavericks seems to manage memory better, not as much swapping).
Symptoms:
lot of beachballs, spinners, even at login time as it tries to restore my old work session
slow keyboard entry in URL address window, slow acceptance of return key. Sometimes takes 2-2 attempts to get it to load a page
application switching is terrible, totally unresponsive sometimes, even though I can see that the CPU is idling (I have Activity Monitor in the Dock with the CPU history as the icon: 4 cores and nothing happening, maybe one of them showing any activity).
Even what I would expect to be lightweight processes — System Preferences, Terminal — take ages to load. I suspect some kind of cache corruption or other damage but have no way to verify. That's not the case in Safe Boot. Things are snappy, as I would expect.
I reinstalled Mavericks last night but no difference. I assume that would remove any kernel extensions or add ons that might have been mucking things up.
Just booted in Safe Boot and used the Guest account, things were pretty speedy, much more like what I want. Logged out of it and into my own account, things are better, very quick to load. So it seems Safe Boot leaves some things out I might be well rid of. Trouble is, I don't know what they are. Another diagnostic would be to create an external boot drive and add my home directory to see if I see any difference there. It might be slower since it's external but maybe not as bad.
How can I isolate what might be causing this?

Safe Mode disables third-party kernel extensions and other startup items.
You need to look at what you have set to startup automatically.
The first place to look is in the Users & Groups system prefs, your account, Login Items.
To delete items from the list, select it and click the - button at the bottom of the list. Unchecking the checkbox does nothing.
The other places where software can install startup items is in your user Library/LaunchAgents, LaunchDaemons, or StartupItems. In the first two, the files will be a single plist. In the StartupItems it will be a folder.
It is best to use the program's uninstaller to remove them, but you can do it manually if you want.
Once you remove them, you will have to log out and log back in.

MBP running Mac OSX Leopard 10.5.8 cannot get past login screen even in safe boot

Help! I have a Macbook Pro purchased in 2009, running Mac OSX Leopard 10.5.8 which froze while running Adobe Illustrator. On reboot, it won't allow me to go past the login screen. I tried starting up from the disc, running disk verification and repair and repairing disk permissions, and trying to start up in safe boot, all to no avail. When the login screen comes up it gives the name of my hard drive with a (2) after it, which seems strange. Any suggestions short of reinstalling the system software? I don't want to lose my applications/data!

Is there any simple software that can boost overall performance or will I have to reformat my MBP? I have a 200gb HD with 50 gb free and 4 gb of ram.
Welcome to Apple's discussion groups.
Launch the Activity Monitor utility. Pull down the list near the top and set it to "All Processes". Click on the "CPU" column heading to put the highest CPU consumers at the top. Also click on the "CPU" tab in the lower part of the window to check the value for "% Idle". If that value is much above zero, check the other categories for signs of resource problems. If nothing there points to a possible problem, launch the Console utility and look for messages that might suggest a problem. If you see messages that you have trouble interpreting, post them here and someone should be able to help.

27" imac yosemite update hangs. Required power cycle and safe boot to get the update going. Now all OS X update do the same.

27" iMac Yosemite update hangs.
The original upgrade to Yosemite (10.10) took almost a full day! The computer hung during one of the reboots and just showed a blank grey screen, no apple logo, no progress bar, nothing. I left it like that for about an hour thinking it might be working in the dark... Eventually I had to power cycle. Disconnected power at the wall outlet for about 5 minutes, then reconnected and tried to start. After about 20 minutes, got to the same point, grey screen:no action, again waited at least an hour.
Then I did a safe boot. System came up OK in safe mode to the log in screen. As soon as I logged in, it proceeded with the interrupted update, which ran to completion. Yay!
Now, every update to Yosemite that arrives gives men the same grief!
To add some more, the "Pro Video Formats 2.0.1" update has installed about 4 times, and is asking to be installed again? There's no indication that it fails the update so whats going on?

I saw the set hibernet mode to 0 trick and it failed. Guess I can try 3 because reinstalling OS X did nothing but cost me another few hours and a little faith in Apple. Getting annoyed as I see how many people complain of the identical issue and the fixes are variable and random. Suggests to me that it is a major design flaw in the hardware and Apple got too cute with the just works idea and didn't put a damned power button on the display so there is no manual way to do it and no 'insert a pin here' type trick to reset the thing.
Asking for a refund tomorrow. Past the 14 days so maybe they'll say no but if so then every time this happens I will swap it out. At least then I know it is a three hour fix and as I was working on this for hours today it occurred to me that if the trick is to do 57 different things and maybe one will work then that is not why I made the switch to Apple. I could plug everything in on my PC and it all 'just worked'.
Really poor customer service - the support folks are very nice and I am sure they know that this is a systemic issue but aren't allowed to say so. Feeling pretty stupid for going on faith right about now.

Hello, what OSX version?
Could be many things, we should start with this...
"Try Disk Utility
1. Insert the Mac OS X Install disc, then restart the computer while holding the C key.
2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu at top of the screen. (In Mac OS X 10.4 or later, you must select your language first.)
*Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.*
3. Click the First Aid tab.
4. Select your Mac OS X volume.
5. Click Repair Disk, (not Repair Permissions). Disk Utility checks and repairs the disk."
http://docs.info.apple.com/article.html?artnum=106214
Then try a Safe Boot, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, reboot when it completes.
(Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive.)
If perchance you can't find your install Disc, at least try it from the Safe Boot part onward.
If 10.7.0 or later...
Bootup holding CMD+r, or the Option/alt key to boot from the Restore partition & use Disk Utility from there to Repair the Disk, then Repair Permissions.
If that doesn't help Reinstall the OS.

What does this log mean? Fresh os install still can only safe boot

*My head is about to explode.*
*Last night, I pulled my old hard drive. put in new one and did fresh install.*
*Ever confident that this would magically fix my computer.*
*I can still only boot in safe mode.*
*I ran AHT. everything passed. I have reseted every thing and reset logic board. yes only one push of the magic button*
*below is a system log from before I put in new drive.*
*however, after new drive and fresh install and still can't boot I check sytem log and still get same message:*
*Cannot use ATS Persistent Store - switching to old FODB cache code*
*Is this my underlying problem?*
*What does it mean?*
*When I try to boot up normally, I get to grey screen , spinning wheel, then wheel turns pixelly and fuzzy with random colors juist where the wheel is and the grey screen with apple logo fuzzy then black.*
*Any words of wisdom will save my sanity.*

thank you thank you for taking an interest. this is so frustrating.
i only have apple keyboard, mighty mouse, and 20 inch cinema display connected. this morning took out memory and tried to boot up with individual pairs in the first bank. first the (2)256, the (2) 1g, and then the other (2) 1g modules. everytime I get the weird fuzzy wheel under the logo after a while, black screen flashes, then grey apple logo fuzzy screen then black forever.
I ran tiger updates this morn. still will only boot to safe mode. then tried to run leopard disk to install it
will not boot from leopard disk.
tried safe boot, then doulble click install leopard, restart, then the saga repeats with the pixely red square around the wheel.
these are fresh drives with only what came on instll disk loaded.
thanks again for taking an interest.
i love this system(well at least i did). I want to install leopard on my powerbook too but am terrified to do so right now since it is working and I have work to do. Can't afford to have no computer to do my work on...self employment is great?!
This is making me crazy. I anxiously await your words of wisdom.

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.

What gets bypassed in Safe Boot?
