Recurring start up problem on iMac

Hi there,
Here is what is happening:
**Start up will hang on a grey screen and not get to finder screen
**Powering down and restarting the computer may allow it to start the finder, after 5 - minutes or so
**Starting the computer in verbose mode, will allow it to start up but the computer will take ages to load the finder. It will run other programs but they will take a long time to load up
**Once the program starts, performance doesn't seem to be affected in any way.
**This problem has straddled both the leopard and snow leopard OSs.
Here's what I've tried
**Reinstall OS (fixes it temporarily but the problem will return after days/weeks)
**Repair permissions (doesn't seem to work. Each time I repair permissions, it seems to repair the same ones each time
**I've noticed that when starting the computer verbose mode, it seems to take ages on the handshaking with the wireless router)
Has anyone noticed this behaviour on their machine? It's hard to find specific information on this problem.
Any advice would be much appreciated.
Dave

Start up in safe mode http://support.apple.com/kb/HT1455 and see if the behavior persists. If so, call AppleCare or carry it into an Apple repair station.

Major start-up problems on IMac - Help, please

My IMac, new in Nov. 2008 and running OS 10.5.5 has been having trouble starting up and staying running over the past 10 days or so. I frequently get freeze-ups and get the grey screen with the flashing folder with a question mark during start-up attempts. I have tried various remedies I got on forums or in the Everything Mac manual including:
unplug and restart
remove peripherals and restart
safe boot
Reset PRAM
Reselect Start-up Disk
Permissions Repair through Disk Utility
Verify Disk through Disk Utility
I ran the hardware test and it said the hardware was OK.
By doing one or another of these methods I can generally get the machine going again (sometimes very slowly and after a few tries), but the freeze-up and restart problems are persisting and getting worse. Today I tried to reboot using the Installation Disk, but it just ejected the disk.
I have Windows XP running with Paralels - don't use it often. Last time I tried it said something about a Fatal Error.
I have backed up most of my important data. I was planning to buy an external hard drive to back up the rest, but I'm not sure I'll be able to complete this at the rate things are going.
Advice, please? Should I just break down and take it to the Apple Store?

I wanted you to know I have been using Apple computers for over 2 decades now and this iMac was the biggest headache EVER!..it would even turn ME to a PC but I have other plans.How many times I had to carry this thing 15 blocks and then they had the NERVE to hand it back to me,once all they did was reinstall the software, I could have done THAT AT HOME!..once the manager of the store hands it back to me,"ALL PROBLEMS SOLVED"!..well they were not..from day one, this was a "LEMON" and no one seems to care, not one person I speak to, not one person in that store....I know computers pretty well, I don't know HOW to write programs but anything other than that, people come to TONY with their problems before Apple Genius bar..what a JOKE that turned out to be!..so here I sit with an iMac,the insurance had run out the day the HARD DRIVE of this iMac decides to stop working...I have NEVER in my life had a dard drive break completely because I am not a heavy user of my computer, no games..and now it's down to emails and my blogs..Apple has changed me but in the wrong direction sadly..I am and always will be an Apple person...I can visit ALL my old Apple comp0uters because when I get a new one, I give my neighbors the old ones..they are STILL WORKING lemom iMac just to check emails and see if I can get it to work but I will tell you the bad sign,very first year I had it, I threw out the box it came in,I live in NYC and as I am taking a walk, a guy is throwing out the box to the SAME iMac..and THEN came the discussion with him about the numerous PROBLEMS On the NEW iMAC!!..I knew right there ,besides me knowing already, it was one big lemon I was stuck with till the end...well the END has finally,thank the gods, come!...and my next computer will be an Apple but not for STYLE, I always went for their great design but Apple has their head so far up an appendage and all about this iPad and iPhone and then the computers come next....believe me, when they sell that many iPhones and iPads...little is done for the real computer customers..and I have NEVER used a cell phone, never had the use for it, so NO iPhone and no iPad cause i love my Kindle...but I will tell you ,I am designing my next Apple computer and it will be that TOWER and then any size screen,maybe two for some reason...and all wireless if possible..but that tower is the ONLY way to go for me but I will use it "low end" not for a business and it's not that ugly and can always be put on the floor BUT YOU DESIGN AND TELL THEM, what you want in it, so you have total comtrol..the screen does NOT even have to be an Apple...but money money drives this company now, while in the past it was the true happy customer THAT MATTERED!! no more...hope you stay with Apple, get a PC(borrow one) and work with it, if you have not cause this iMac is NOT the way an Apple computer should act and turn you off to our community...and that's the other thing, Apple users, used to be a "community" cause we were the "small company that didn't make it"!...so we all stuck it out for so many years....helped each other out

Start up problems on iMac version 10.7.3

i recently bought a brand new 27 inch imac intel core duo i5. it has the latest software 10.7.3.
sometimes when i start it up it takes ages to load then i have to "log in" however i haven't selected to log in. when it finally loads its really glitchy and my wifi doesn't work. it basically says that my computer doesn't have wifi installed. and by glitchy i mean when i scroll over the dock all these random lines appear. it's not a smooth process. i then have to restart my computer and it loads up fast and i don't have to log in then everything is fine.
is anyone else experiencing anything similar? i don't know what to do, any help would be great!

Your warranty includes 90 days of phone support. Call AppleCare and let them figure it out. If you bought it directly from Apple, you have 14 days to return it for a full refund or exchange.

Start up problems with iMac

when re connecting the power and pushing the on button, the typical start up sound is produced but the screen stays white. After a few moments the 'file' icon appears in the middle of the white screen with a question mark flashing in this icon.

Hello Veke,
Try holding the Option or alt key down at bootup, what shows as boot choices?

New iMac crashes, start up problems, flicker screen...

Purchased iMac four months ago. It seems to be a bit flaky – as a life-long and loyal user of Apple, not what I was expecting! Often have problems crashing or hard disc error messages at start up. Flickering screen.
Also not sure that I got everything that I requested at the store – I had asked for an additional back up drive in store when ordered and I've looked on my iMac and it doesn't seem to have this. Currently backing up to iCloud and on DVDs to make sure I don't lose anything if my computer gives up the ghost and dies!
Bit disappointed really. Never had problems with any Apple products before and saved up for quite a while to upgrade my very old G4 (which still runs like a dream, and only updated because it's operating system became incompatible with latest software updates) to a new iMac (which seems a bit buggy).
Asked around and a few people have found iMac to be less reliable than previous Apple computers. Anyone else have problems with iMac seeming less stable?

Contact Apple Service, iMac Service or Apple's Express Lane. Do note that if you have AppleCare's protection plan and you're within 50 miles (80 KM) of an Apple repair station, you're eligible for onsite repair since yours is a desktop machine.
You'll have to take up the missing backup drive with the sellers. The iMac doesn't come with one.

I had a problem with imac screen going black. apple store diagnosed prob with video card which they replaced. Brought it home, turned it on (have done this 4 times) it starts up, wheel turns, there is a long bar at bottom which fills up, then it turns off

Start up problems, including from installation disc.

Hello everyone in the Apple ether, I need your help!
I have a powerpc based iMac G5 at home that I set up for my mum to use once I bought my macbook. I finally managed to win her over with talks of how much easier it would be for her to manage her photos in iPhoto, and everything was going really well. I recently came home after my final year at uni and some travelling to find that the computer is taking a long time to start up. This can be in both the grey apple loading screen but also once it logs in it can take a long time to display anything over than the desktop background, and even once it displays other items any attempt to open anything just results in a spinning wheel icon. At the worst case it has taken about 20 minutes to get going.
Once it has fully booted, the machine doesn't appear to be working any slower than normal. I tried using disk utility in mac OSX and verifying permissions etc and that didn't do anything. I then tried googling the problem and came across this article on the apple web site. http://support.apple.com/kb/TS1417
Starting in Safe Mode did not resolve the issue so after backing everything up I tried starting from the installation disc. This is not something I have ever done before and as someone that never really delves beneath the surface of her machines I was a bit scared of doing it. But I put the disc in and restarted and held down C just after I heard the chime, and shortly after it all went wrong. The screen went grey and all I could see was the image you get when it crashes (you know, the power sign with text over it saying you need to restart) with lines of code all down the left of the screen. I took a photo of the screen on my camera so can give details of the code if you need them. The last line said
Kernel version:
Darwin Kernel Version 8.8.3: Wed Oct 18 22:00:38 PDT 2006; root:xnu-792.15.4.obj-4/RELEASE_PPC
panic: We are hanging here...
After a few minutes on this screen the fan started working overtime and after about 5 minutes of that I just turned it off using the power button on the back. The machine has since started up normally (ie slowly) but is working fine.
So I was wondering if anyone had any ideas how to fix the slow start up problem without booting from my install disc, or indeed if anyone could suggest why I can't boot from my install disc? Thanks very much for your time and help.

It appears you experienced a kernel panic which is hardware related. A few suggestions for you to try:
Except for the keyboard & mouse, disconnect all devices from the computer & try the suggestions mentioned in the following:
http://docs.info.apple.com/article.html?artnum=106805 Mac OS X: "Broken folder" icon, prohibitory sign, or *kernel panic* when computer starts
User Tips: Kernel Panics
==============
Boot up from your Tiger or Leopard Install DVD while holding down the "c" key.
Select the language you wish to use, and then choose *"Disk Utility"* from the menu bar.
Your HD should appear in a panel on the left hand side of the window which opens. Select it and then click on the *"repair disk"* button in the right hand section of the window.
Once this process has been completed restart your computer and run *repair permissions* from Disk Utility.
* If Disk Utility (from the install DVD or HD)is unable to complete the repair, you will need to use a stronger 3rd party utility like DiskWarrior, Techtool PRO (not Deluxe) or Drive Genius.

During the start up of my imac, logon failed

during the start up of my imac, logon failed and the user doesn't exit anymore . i have performed a password recovery and i'm using the mac root user. is it possible to recover my user and my profile ? and how ?
this problem exist from the moment in which i had change my id apple .
thanks

Ifd you go to /Users does your home folder still exists? If so, then go into Accouns and make a new user account with your same name, and this is very important, same short name. When you do, you will get a message that a home folder already existsd and would you like to use it, say yes and then log out and your account should be there. If there is no home folder your only option is to restore from a backup.

Start-Up new 27" iMac

I have used top of the line Dell XPS systems for the past 15 years. I have decided to jump ship and I ordered a loaded iMac. My question is there any advice you can give me in starting up my ne iMac for the first time. Also what are the main issues I will run into since my brain is a PC wired brain?
Thanks for any advice

Is it true I do not need Norton or McAfee or any other security software?
Absolutely! Whatever you do PLEASE do not install those on your computer they tend to create more problems than they ever solve.
In short there are NO virus's that affect OS X currently. I've been operating without any malware for 3 years despite not using any anti virus software.
If you choose to run Windoze on your Mac then the Windoze partition will be susceptible to Malware and virus's as is any Windoze computer. If somehow the Windoze partition becomes infected it will NOT affect the OS X partition at all.
Is MainMenu a good program for the iMac?
I don't use MainMenu, I've only used Spotlight to launch applications and locate files. You will find launching apps and locating just about anything on you Mac with Spotlight is very simple. It's the magnifying glass symbol in the upper right of the screen. It can also be launched by holding down the Command key and spacebar. For example if I want to start Safari I can click on the Safari icon in the Dock however what I like to do is hit Command-Spacebar then type Safari and Spotlight finds it and I'm running.
Here is a Wikipedia article that provides more insight into Spotlight.
NOTE: I just looked up what MainMenu is and see I was totally off target by describing Spotlight. However the answer is NO I don't see a need to use MainMenu. Macs very rarely need any maintenance by the user. Part of OS X is it runs daily, weekly and monthly maintenance. This is usually done in the middle of the night and needs no user intervention. One utility I will use from time to time is called OnyX (Google it) which I find very good. BTW Apple recommends not shutting down your computer, in the owners manual it says to only shut it down if you are going to be away for a few days. In the preferences you can set the monitor and system to sleep after X amount of minutes that you specify. For example I have mine set to sleep after 15 minutes of non use.

Recurring disk permission problems.

I am having recurring disk permission problems on my MacBook Air (Rev. A 1.6GHz/OS X 10.6.6).I am using Onyx to verify and repair disk permissions, but after about a week the computer seems to slow down and respond strangely. I run Onyx again, and it repairs many disk permissions, but the same thing happens again after about a week. Below is the log from a repair disk permissions that I ran through Onyx earlier today.
What can I do to fix this problem? Any help would be greatly appreciated!

Start up problems and screen shake

Dear all
I have started experiencing problems when I start up my iMac. Prior to the Blue Apple Screen appearing on startup I get a fuzzy grey screen with thin lines moving up and down the screen. This lasts for about 5 seconds then clears when the Blue Apple screen comes on. It never used to do this.
Once I am logged in my screen tends to have a series of small dots (like pixels) forming short lines across the screen. These change each time I log on.
Also, when this has happened the whole screen goes 'fuzzy' for a few seconds before clearing again. This can re-occur at any moment.
This problem does not always happen but maybe three out of four start ups. If the problem at start up does not occur then I do not experience the fuzzy screen.
Any ideas? I am very concerned that something critical is up.
I have done the most recent updates.
ps I am not a computer whiz!
Regards
Adam

Hi Adam,
This is exactly what is happening to my iMac which will be repaired this week. It is critical but it is due to a known fault on some of the iMacs.
Go to http://www.apple.com/support/imac/repairextensionprogram/
Even if your iMac is out of the 1 year warrenty it will be covered for this.

Start-up problems due to firewire/usb devices?

Hi
recently, my imac G5 has been having some strange start-up problems. It had been working fine for the previous 11 months I have used the machine.
The start-up problems occur mainly after the computer has been shut down for some time (eg in the morning). When I press the start-up button, the computer will make the start up noise and then get stuck on the blue screen. Sometimes (but not always) the fan will start making a loud noise. Sometimes it is possible to turn the computer off and try to restart with the button at the back of the computer, at other times I have to turn the computer off at the power point and start again. I have tried to start up in "safe mode", but that also does not always work. This morning I was only able to start up the computer after unplugging all external devices, after which the imac started fine. I then replugged everything - no problem. However, I would like to be able to start-up without having to unplug and replug my various devices!
I am using several firewire devices (LaCie 250gb external hard-drive, Cd and DVD burner) and USB devices (scanner, printer, external USB drive (which I use for back-ups and which is mostly removed from the computer).
I have run disk utility to check the hard drives - they all appear to be ok.
I have a feeling the problems may have started when I tried out some back-up software to set up a regular back-up scheme. I have now removed all scheduling from my back-up software (silverkeeper, synk) but the problem remains.
Is it possible there is some problem with the drivers for the external devices? Any ideas?
Thanks a lot

Hi Barbara,
Yes, USB devices particularly (including some hubs, most USB adsl modems, some printers and scanners and the like) can most certainly be the cause of this sort of problem (By far the most common cause, in fact)
First step is to simply remove them all, and see if the problem goes away. If so, then try adding them one at a time directly connected to the computer, testing them for a while, and see whether you can pin down which one it is.
Once you have tracked it down, if the device has its own drivers then look for any updates on the manufacturers web site, of course.
If the device doesn't have its own drivers then you can try simply disconnecting before shutting down and reconnecting after starting up, but the best solution is usually to replace the device.
(For what its worth, my bet, in the absence of more information about the actual devices attached, and as long as you don't have a USB adsl modem, is that its going to be a USB hub causing the problems )
Cheers
Rod

Start-Up Problems = Frustrating :D

Howdy
Alright. So I've had my iMac 24" , 2.8GHz since Feb08 and it's been awesome until recently, putting the computer to sleep freezes everything and requires me to reboot the entire machine. But! That's only the first part of it.
The computer overall runs normally, but turning it off means a world of wonders to turn back on.
• The screen does not show the apple logo, no flashing ? either.. just plain white
• control + command + p + r = apple logo, turns into a circle with a diagonal line as shown here: http://support.apple.com/kb/TS1892?viewlocale=en_US
• I have a bootcamp installation, so I tried pressing the Alt /Option key to try and boot into windows but the partitions do not show up, the cursor appears perfectly though.
• Pulling the plug after turning the mac off for 30 seconds along with ALL the written documentation on "Start Up Problems" in the guides both online and offline failed to do anything.
• Hardware Check passed with flying colours.
• Disk Checks both verification through cd and permissions within the system passed with no problems.
Anyone else get this lovely problem? Please help me out here before I start manually pulling my hair individually. ty

Hi there:
The symptom(s) you note are among some shown to be in
the group known as a 'kernel panic' and so that may be due
to either (or both) software and/or hardware.
Sometimes, there is a software conflict; so if something was
added to the system which makes a conflict, there is a chance
that a kernel panic may result; however slim that would be.
And if something in one of the folders you can see on the
base level (as icons, etc) in the hard disk drive have been
moved, modified, or somehow otherwise changed from
their original content, character or quality: a kernel panic.
Have you been able to boot the computer from the Installer
disc and run that disc's version of Disk Utility from that item's
own Menu bar? This is short of running the Installer, since
there are options in the menu bar once the Installer is visible.
You can try and see if the tool, Disk Utility, can repair disk;
and repair disk permissions, plus a few other things.
Sometimes, the 'kernel panic' is a matter of trial and error
troubleshooting (a process of elimination) to see what is
an answer by trying everything; then you have solved it.
One of the old standbys for resolving kernel panics has been:
"Resolving Kernel Panics"
http://www.thexlab.com/faqs/kernelpanics.html
Another source of similar yet slightly different information, is:
"Technical Note TN2063: Understanding and Debugging Kernel Panics"
http://developer.apple.com/technotes/tn2002/tn2063.html
If any files on the root or base level of the hard disk drive have
been removed, renamed, or somehow changed, there may be
a problem in starting up and running the computer. So, if you
can (and - nothing - else works) boot from the Installer disc, and
repair disk, repair disk permissions, an you are at a total loss,
you may try and see if a new system will work. To do this, you
would continue in the Installer past these Utilities and try to
install using an option known as "archive & install" and be sure
to note a checkbox may be required for this to keep your old
settings current in the new system folder it would create.
That may work. And it may be of help to read up on how to
"archive & install" a new system folder. You would also have
to upgrade this new system to whatever current versions of
system software and not overload it with a huge pile of them
at once. To install a few items (often downloads from Support
or choose the automatic Software Update, but not let it install
all that it finds at one setting) and be sure to run Disk Utility's
'repair disk permissions' between installations of software items.
{Before going through all this, have you tried to start the computer
with the Shift - key held down, so you can log into the system in
SafeBoot/Safemode? Then if you can, use the internal Disk Utility
to 'repair disk permissions', then note the repair comments; and
quit Disk Utility, then choose to restart the computer normally.}
You still may have to read through the 'resolving kernel panics'
but there may be some easier way out, instead of installing a
new system folder and upgrading it. There is a reason for this
issue; so something must have been changed in the system.
PS: And if nothing else, the issue may not be directly related to
the 'kernel panic' so you could try reading among these related
results from a search I just did on the "dreaded white screen..."
• ' iMac white screen at startup ' - google search:

Good luck & happy computing!

Problems with iMac G5 and LaCie external drives

I have an early iMac G5 (without iSight), running OS 10.5.2. I've had a 250GB LaCie external hard drive for about a year now, and it worked fine up until a couple weeks ago, when I got this message:
Disk Repair
The disk "External HD" was not repairable by this computer. It is being made available to you with limited functionality. You must back up your data and reformat the disk as soon as possible."
I was unable to save anything to the drive after this, including altering files already on the drive. Long story short, I bought another LaCie drive, because I needed more space anyway. I got the 500 GB model, moved everything onto it, erased the old drive, and then I had two working drives. I've since only been using the new drive, but just a few days later, I got the same message again, and am having the same problem, but this time for the new drive. I'm not a computer-savvy person, so I have no idea what could be causing this. This happened not long after updating to OS 10.5 from 10.4 - I'm not sure if this could be related. Can anyone help?

One thing to look out for is the power source. If you have a huge octopus of power cords plugged into one outlet, the drive may not be getting enough power to operate properly. That would explain why the same thing happened on two separate drives, both recently. You may have added something new to the +power strip+ that is overtaxing the available power draw.
Someone I know had this issue. It never occurred to him or me to consider this possibility. His external drive was regularly getting disk directory errors. I initially thought the drive was going bad, but once we distributed the power cords to two power strips connected to different outlets, the problem did not recur.
Your problem may be something else, but it sounded too familiar to not mention my experience with the power cord octopus monster.
