Why does my imac start up in safe mode

hi, imac starts up in safe mode. not every time, only when progress bar appears at startup.
I have had the Logic board replaced under warranty but it still started in safe mode.
sometimes when it has started the wifi symbol is missing and no wifi, other times the sound is not there and the symbol is missing on the top bar.
I then have to restart and it comes up good. sometimes the desktop top bar is not there until I press the mouse and then it appears.
don't know what to do, any Ideas anybody?

How often does this happen? Do you have automatic updating enabled in Software Update? If so, then it's possible those were firmware updates being installed, not startup in safe mode. In a safe mode startup you are initially prompted for your password before proceeding past login.
If a firmware update was happening then the computer will restart on its own. If you interrupt the process then the update isn't installed, so it will try again on the next restart.
Safe mode is initiated by holding down the SHIFT key at restart. It should not occur without user intercession.

Why does my iMac run fine in Safe Mode but has many problems when it isn't?

If you take a look at my previous posts you will see that I have had the usual problems that many, many other iMac G5 1.8 20" Rev A owners have been recently experiencing (Kernel Panics, Screen Blurs, Screen darker at top more than bottom, etc)
I have discovered that the only way to stop all the numerous problems that I have been having is to start the iMac up in Safe Boot Mode
In this mode it has been running Perfect! No Crashes! No Screen Problems! It's been wonderful to get it back to normal after all the peristant problems I have had! The only thing being that you can't use sound in or out or the DVD Player with Safe Mode!
So the question I would like to ask is:
So does this mean that the problems I had before were just Software conflicts/issues and not Hardware ones?
Cheers for your help
Bob
iMac G5 1.8 20" Mac OS X (10.4.3) 2 Gig RAM

When you start up in Safe Mode various things aren't loaded at startup, Bob.
Have a thinbk about which of the following may be involved in your own case:
It forces a directory check of the startup volume.
It loads only required kernel extensions (some of the items in /System/Library/Extensions).
It runs only Apple-installed startup items (some of the items in /Library/StartupItems and /System/Library/StartupItems - and different than login items).
Mac OS X 10.4 Tiger only: It disables all fonts other than those in /System/Library/Fonts .
Mac OS X 10.4 Tiger only: It moves to the Trash all font caches normally stored in /Library/Caches/com.apple.ATS/(uid)/ , where (uid) is a user ID number such as 501.
Mac OS X 10.4 Tiger only: It disables any Login Items.
(from http://docs.info.apple.com/article.html?artnum=107392)
Have a look at http://docs.info.apple.com/article.html?artnum=106464 for some more possibilities.
You may find it worth while using System Prefernces/Accounts to creat a new admin user account and see if the problem persists with it. THis may help you narrow down the problem further.

Why does it say in the Firefox Safe Mode article that all of the changes are temporary while in Safe Mode, then later it says "Note: The following changes cannot be undone."?

Why does it say in the Firefox Safe Mode article that all of the changes are temporary while in Safe Mode, then later it says "Note: The following changes cannot be undone."?

When you open Firefox in Safe Mode, it automatically disables your custom settings, themes, and add-ons. THOSE changes are temporary.
However, if you click any of the boxes underneath the line, "You can make some or all of these changes permanent", and then choose "Make Changes and Restart", everything you checked will be forever changed, even when you start Firefox again in 'normal' mode. [See attached image for a preview of the Safe Mode options].
To be clear:
1. If you check any of the boxes but do NOT select "Make changes and restart", those things will not be changed at all in safe mode.
2. If you select any of the boxes and you DO select "Make changes and restart", you will permanently lose any of the items you checked (bookmarks (except for backups), user preferences, etc.).
If you performed the action in step 2 above, you will only be able to restore those things if you have a previously created back-up of your Mozilla Profiles folder (not the same as the Firefox program folder).
Hope this helps.

Why will my iMac boot fine in Safe Mode but freezes on a normal boot?

It is a 17" iMac. 1.83Ghz Core 2 Duo. 1GB RAM. 160GB Hard Drive. Combo Drive with Intel GMA 950 GPU.
I took out the screen and put in in a different computer a while back. This was a working computer before hand. I pulled it off the shelf the other day to get it going (using an External Monitor) and when it gets past the Apple Screen, it goes to the blue screen, and then loads the wallpaper and some of the taskbar, but no dock and it freezes. (This is on a fresh install of Leopard). When I boot to safe mode, it boots fine. I have tried reseating RAM, different RAM sticks, and a different hard drive. Also replaced PRAM battery. Done a SMC reset and a PRAM reset. No change.
Also worth noting was that when I tried to boot my Leopard disc, it would freeze at the Choose Language screen. So I took the HD out and installed Leopard thru my other iMac and reinstalled OS X. Did the same thing when I tried to boot from a Snow Leopard disc.
Ideas??

Hello, in Safe Mode did you try setting a good resolution on the Display?
One way to test is to Safe Boot from the HD, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, Test for problem in Safe Mode...
PS. Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive
Reboot, test again.
If it only does it in Regular Boot, then it could be some hardware problem like Video card, (Quartz is turned off in Safe Mode), or Airport, or 3rd party add-on, Check System Preferences>Accounts>Login Items window to see if it or something relevant is listed.
Check the System Preferences>Other Row, for 3rd party Pref Panes.
Also look in these if they exist, some are invisible...
/private/var/run/StartupItems
/Library/StartupItems
/System/Library/StartupItems
/System/Library/LaunchDaemons
/Library/LaunchDaemons
See this great post by themachead on how to list the extensions in Safe Mode with System Profiler then compare to the extension folder!

I shut down my macbook pro and now I started up and it started in the safe mode

I shut down my MacBook Pro yesterday and when I started up today, it keeps starting up in safe mode, what do I need to do?

Welcome to the Apple Support Communities
Does your Mac start properly in safe mode? If so, try resetting the PRAM > http://support.apple.com/kb/HT1379 This will reset the "boot args", so OS X should start into safe mode. Also, you should verify that the storage of the computer is OK, so open Disk Utility, select "Macintosh HD" on the sidebar and verify the drive. If there's a problem, start in OS X Recovery (holding Command and R keys while your Mac is starting) and repair it

Why does my iMac display go off when I am starting up or waking up my machine from sleep..

Why does my iMac display go off when I am starting up or waking up my machine from sleep..?
When my iMac goes to sleep I then later try to click the magic track pad or keyboard and it will usually then show the initial password entry login screen and then go off. The machine is still on but the display is black and will sometimes flash up the screen again if I press the magic track pad or keyboard but will then black out again..

Well, there are many different reasons why it does this. It might shut off due to power voltage problems, system overheats, or there is a System Problem. The reason it might be hard to boot up is because your power button might not work properly or your system hard drive is damaged.

Why does my macbook pro only start up in safe mode?

Last night i updated my macbook pro, and when it restarted it stopped at the logo with the spinning wheel, and it kept spinning for 20+ minutes. I shut it down by holding the button, and it will not start up again, every time the wheel just keeps spinning. I tried holding down shift, and starting it in safe mode, and that seemed to work. But that is the only way it will boot up, and I am limited to what I can do. How can I start my macbook pro up with out safe mode. I do not have my installation disk with me, and I do not have any of my stuff backed up, but I plan on purchasing a external hard drive within the next week to back up everything, incase I have to wipe my hard drive. But I will only do that at last resort...

MacBook Pro 3,1 15' 2,2 Core 2 Duo Late 2007.
I used the same buss speed (667 mhz) and the same type DDR2. Same number of pins.
I also checked what happened with 0 ram in slots, and then it started blinking constantly.
So it must see the RAM but the RAM seems useless for some reason...

Why does my Imac screen slide and I lose my screen? It goes back to my desktop. Then sometimes my screen goes to full screen and I don't know how to get out of it.

Why does my Imac screen slide and I lose my screen ~ It goes back to my desktop.
Then sometimes my screen goes to full screen without me doing any commands, and I don't know how to get out of it without going to force quit and starting all over.

Hi,
When it goes full screen try moving the mouse up to top right of scren & see if there a double diagonal Arrow to click on.
On the other see if it's the silly implentation of Spaces/Mission Control/Expose in ML...

Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you turn on the computer, and again when you log in.
Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a Fusion Drive or a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to start up and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal startup may also be somewhat slow.
The login screen appears even if you usually login automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Test while in safe mode. Same problem?
After testing, restart as usual (not in safe mode) and verify that you still have the problem. Post the results of the test.

That panic was not caused by third-party software. If the problem is recurrent, the possibilities are:
A stale or corrupt kernel cache
A damaged OS X installation
A fault in a peripheral device, if any
Corrupt non-volatile memory (NVRAM)
An internal hardware fault (including incompatible memory)
An obscure bug in OS X
You may already have ruled out some of these.
Rule out #1 by starting up in safe mode and then restarting as usual. Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a Fusion Drive or a software RAID, you can’t do this. Post for further instructions.
You can rule out #2 and #3 by reinstalling the OS and testing with non-essential peripherals disconnected and aftermarket expansion cards removed, if applicable. Sometimes a clean reinstallation may solve a problem that isn't solved by reinstalling in place.
Corrupt NVRAM, which rarely causes panics, can be ruled out by resetting it.
If your model has user-replaceable memory, and you've upgraded the memory modules, reinstall the original memory and see whether there's any improvement. Be careful not to touch the gold contacts. Clean them with a mild solvent such as rubbing alcohol. Aftermarket memory must exactly match the technical specifications of the machine.
Apple Diagnostics or the Apple Hardware Test, though generally unreliable, will sometimes detect a fault. A negative test can't be depended on. Run the extended version of the test, if applicable.
In the category of obscure bugs, reports suggest that FileVault may trigger kernel traps under some unknown conditions. Most, though not all, of these reports seem to involve starting up from an aftermarket SSD. If those conditions apply to you, try deactivating FileVault.
Even if FileVault is not active, an aftermarket SSD may be the cause of kernel panics. Check the manufacturer's website for a firmware update.
Connecting more than one display is another reported trigger for OS X bugs.
If the system is not fully up to date, running Software Update might get you a bug fix.
In rare cases, a malformed network packet from a defective router or other network device can cause panics. Such packets could also be sent deliberately by a skillful attacker. This possibility is something to consider if you run a public server that might be the target of such an attack.
Otherwise, make a "Genius" appointment at an Apple Store, or go to another authorized service provider to have the machine tested. You may have to leave it there for several days. There isn't much point in doing this unless you can reproduce the panic, or if you can't, it happens often enough that it's likely to be repeated at the store. Otherwise you may be told that nothing is wrong.
Print the first page of the panic report and bring it with you.

My MB is always starting up in safe mode... why? What to do to start-up normally? Please help.

Hi,
I am frequently having troubles with my MB. Different types of troubles. Couldn't solve a single one yet.
I have performed reboot MB in safe mode-- hold down the left shift key after the start up tone till the spinning gear appeared.
Few hours back i performed that, and since then it just starting up in safe mode without holding the any shift key. I have password protected log-in and each time the dialog box shown the safe mode, not the normal boot as it used to be. I restarted so many times, but same result.
I started-up by holding down the Option key, dialog box showing the same thing "safe mode" and same result.
I started-up in single user mode, and then typed reboot, then pressed enter/return button, but dialog box shown the same and it started up in safe mode after entering the password.
While in the safe mode, i have selected the Mac OS X 10.4.11 from the preference pane, then restarted, but all produced the same result, same dialog box showing the safe mode.
I couldn't take the screen shot of that dialog box that appears before starting up.
I am currently using the internet while in safe mode, and using ethernet adapter- a AirStream 1100 F25 external modem attached to the USB port. I don't know if that is good for my MB to use internet on the safe mode.
I used disk utility and verified the disk during the safe mode, i don't know if that is right or wrong to perform that utility in safe mode, but it all appeared as normal. You can see that from the following image.
Few days back, i performed the disk utility to verify disk while on the normal boot. But the result shown the red marks, please see the following image for details.

Please help me out. Let me know how to start-up normally. By the way, my superdrive is not detecting DVDs including the OS dvds, but it read and write the CDs. So, It is not possible to reinstall OS early, at least not before the having the back up of the data. Please help me with contingency plan/s or as you think fit.
Thank you. Look forward to your reply.

Maximillianmann,
depending upon how full “almost full” actually is, that could be the problem.
You can try this, if you have Mac OS X 10.7 or newer installed, to see if it’s not related to your disk being almost full: boot your MacBook Pro into Recovery mode by holding down a Command key and the R key as it starts up. Once the Mac OS X Utilities menu appears, select Disk Utility. On the left-hand side of the Disk Utility window, select your internal disk’s boot partition (typically called “Macintosh HD”). On the right-hand side, press the Verify Disk button if it’s not greyed out; if it is greyed out, or if it reports that errors were found, press the Repair Disk button. Once the verification/repair is completed, exit Disk Utility and select Restart from the Apple menu to restart in normal mode. Once you hear the startup chime, try booting into Safe mode; does it let you do so now?

Why does my iMac only have 1 GB of memory? I hardly have anything on here. I cannot download software update in order to get Turbo Tax to work.

Why does my iMac only have 1 GB of memory?

Put in more RAM. Visit OWC, DataMem, or Crucial.com to purchase memory for your model. You computer would have more memory had you put more in a long time ago.

Why does my iMac appear many times in my network and labelled 1,2,3, etc

why does my iMac appear many times in my network and labelled 1,2,3, etc

Ok, I solved it.
I followed this steps:
1- Turn Off Wi-Fi from the Wireless menu item
2- From the OS X Finder, hit Command+Shift+G and enter the following path:
/Library/Preferences/SystemConfiguration/
3- Within this folder locate and select the following files:
com.apple.airport.preferences.plist
 com.apple.network.identification.plist
com.apple.wifi.message-tracer.plist 
NetworkInterfaces.plist 
preferences.plist
4- Move all of these files into a folder on your Desktop called ‘wifi backups’ or something similar – we’re backing these up just in case you break something but if you regularly backup your Mac you can just delete the files instead since you could restore from Time Machine if needed.
5- Reboot the Mac
6- Turn ON WI-Fi from the wireless network menu again
