Mac pro still hangs on the blue screen on start up.

Hi.
my mac pro still hangs for ages on the blue screen before the login page where i input my password appears.
i've tried starting up in command-V and that didn't work.
i thought snow leopard was meant to improve, it has just slowed my start up down greatly!
could someone please advise on how to fix this?
thanks
Dan.

Hi boom,
Have you tried downloading and re-applying the latest Combo update?
If not, go to the apple download page, find the Combo update (couple of hundred MB) and install it.
This has fixed various issues in the past for numerous users... it might do the trick for you.
After it's installed and rebooted, repair permissions and reboot again.
Also check to see (using software update) if there are no firmware updates available for you.
And, make sure the OS drive's root is clean, just the basic Applications, Library, System and Users folders, no other mess. If there are 'Previous System' folders from earlier Archive & Install situations you might want to remove those.
Finally, if you upgraded from a PowerPC to Intel using the Migration Assistant the symptoms you are describing are very common, the migration assistant well... it ***** :/

Can't get past the blue screen with "starting Mac OS X"

I am having problems with starting my iMac. It gets to the blue screen with "starting Mac OS X" but won't go beyond that point. I was able to get the disc drive open with the help of other posts, holding down the mouse while turning on the computer, but the drive won't stay closed with the install disc in it. I have even tried holding down the "c" key while restarting the computer and it wouldn't work. Any help would be greatly appreciated. So much info that I could really use. Also, please keep in mind that I am not too computer savy. Simple language please.
Thanks

If the steps I provided in my earlier post are not helping, then I see your options at this point as follows:
1. Run the Apple Hardware Test (AHT) that came the affected computer. See my "Apple Hardware Test" FAQ for comprehensive advice on using the AHT in troubleshooting.
2. Performing an Archive and Install. For important tips on this, see my "General advice on performing an Archive and Install" FAQ. Perform the steps therein in the specified order.
3. Take the computer in for service. If there is an Apple Retail Store in your area, I'd recommend taking it there. You may wish to call ahead to make an appointment at the Genius Bar.
Good luck!

MAC DUO won't go past BLUE SCREEN on start-up.

Please help!
My mac duo has crashed after a mac software update. Now it won't logon past the blue screen!
I've tried everything online like DISK UTILITY on Mac os x disc and SAFE MODE but no joy whatsoever.
SAFE MODE won't work now after doing it three times. Is this typical?
Should I re-install the MAC OS X using the option to copy existing files and applications?
Any help would be greatly appreciated.

There are two major problems out there right now. That is also part of the problem. We are not used to two problems in our domain.
I own 20 Mac's in my office, and I only did the latest updates on my MacBook Pro 17-inch portable and my G5 Dual 2.3 GHz desktop that has two 30-inch Cinema Displays. Both machines had the Adobe CS 2 Professional Suite with Acrobat Professional.
I had both of the prevailing update problems on my MacBook Pro—1) unable to restart and 2) Acrobat crashing the system.
On the G5, I only had the 1) unable to restart problem.
I won't update the other machines until these problems are resolved by the OEMs.
1) Unable to Restart. Of the two major hiccups out there, the link below indicates Quicktime's update is the source of the 1) unable to restart problem, fixed by deleting startup items, I believe. Again, I had this 1) unable to restart problem on both operating systems (PPC and Intel versions). Recovery of the 1) unable to restart problem is done in in Safe Mode by holding down the Shift key when restarting. This may take a long time to reboot, so keep holding down the shift key until the grey screen and startup wheel is seen. Then delete all startup items and Adobe Version Cue if you have it. (Use Version Cue Uninstaller.)
http://www.macworld.com/news/2006/05/24/cs2quicktime/index.php
2) Acrobat Crashing the System. Acrobat's freezing the entire OS 10.4.6 system is a result of the Security Update 2006-003, fixed by rolling back to a pre-Security Update state using Archive & Install for re-installation of the OS. Archive & Install does not erase your files or network settings. Printers may need to be re-added.
Apple has released two products (QT 7.1 and SU 2006-003) that fouled these systems. Bad Quality Assurance, I think. I am not sure if the Security Update problem is an Apple or an Adobe software problem, i.e., Adobe may have not followed some software guidance from Apple in Acrobat 7.07 or earlier versions. I am certain both companies are aware of the problem, but I am uncertain of the fix for Acrobat. We probably do need to update for security, but I can't live without Acrobat. So I will wait it out sans Security Update 2006-003.

Is the blue screen on start up normal

when I startup my macbook pro that I just got the screen goes gray with the apple logo then right before the screen where I put in my password it goes blue for about 8 seconds.When I shut down my computer the screen goes blue as well.I've never had a mac before so I don't know if the blue screen is normal or not.Should I contact apple support for help or is that a normal thing?

This often happens if the permissions, directory, or hard drive is damaged. Is your data backed up? Only then can we safely examine the drive.

Mac Pro gets stuck on the grey screen and won't finish booting

I have a Mac Pro 1, 1 recently (successfully) upgraded to snow leopard that gets stuck on the grey screen with the spinning rainbow cursor (after the apple logo and brief blue screen) and won't finish booting up. This happened after my computer froze up and I had to force quit. I checked out the forums and I tried all the all the suggestions (like disconnecting peripherals) and appropriate disk utilities, saw no errors with the HD reported, and had no trouble doing a safe boot (everything works o.k. there) or starting up from the software disk to perform the repairs. I did notice that during the repair permissions command, it gets stuck in the last few minutes, the CD starts to chug along, and everything freezes and I have to force quit. This happens every time I try it. I eventually backed everything up, erased the HD and reinstalled the OS, reset PRAM and NVRAM, but I'm still getting the grey screen on restart. Tech tool deluxe reports a "fail" on the video RAM, but everything else seems to check out. Could it be a graphics card issue? I did notice some funky visual glitches occurring prior to the breakdown. Any other ideas?

I wouldn't trust Apple Disk Utility to do a hard drive repair, but I would go with TechTool Pro 5/6 if you have that instead of Disk Warrior from Alsoft.
Clone the drive, though you should have some bootable backup clones already; repair the clone; then boot and work from that drive. Always have a working copy of the system.
And off load all your data to other drives.

Why does my 27" iMac running OS 10.6.8 hang on the grey screen at start up?

My 27" iMac, running OS 10.6.8, has started running slowly when loading Apps and when running Safari. Also, when powered, on It has started stopping on the grey screen before the Apple logo displays. To get past this I must turn the Mac off and then back on. Does anyone know what would be causing this behaviour and what I should try for a fix?

It could be a sign of an impending harddrive failure. If you don't backup regularly, I would strongly suggest you start. Don't run ANY anti-virus software as it really messes with your system and if you do regular software updates you'll be fine there.
OnyX for MAC is a good application to clean out those cob webs:

Stuck at Blue Screen on start up

My MacBook Pro gets stuck on the blue screen at start up. Have tried all the obvious fixes but no joy.
I put my mac in target mode and connected to another MacBook Pro
Then selected my HDD as the start up disc, rebooted, and this worked fine, i was able to run my HDD and all software fine.
I conclude this shows i have a hardware problem on my mac.
Can anyone please give me a clue as to what it might be? or is it time for a visit to the apple store (and a remortgage on the house)?
Many thanks Phil.

I know you already mentioned that you "Tried all the obvious fixes" but this is the first thing that came to mind when I read your problem.
Hold down the power button until your Macintosh shuts off.
Then hold down the power button until the white light on the front of your Macintosh starts flashing rapidly.
Then release the button and see if your device boots up normally.
I had this very same problem happen to me a few weeks ago and I was able to solve it by doing those few steps.
Hope this helps!

Help! I can't get past the blue screen

I was having problems with my iMac last week with it freezing while doing my normal stuff. I force quit everything and restarted. This went on 3 or 4 times in one night. I shut it down for the night. The next morning, I started it up and it wouldn't get past the blue screen. It first got to the screen with the progression bar on the blue screen. So i did the troubleshooting in the manual. I had to go buy the USB mouse because I couldn't do it with my bluetooth mouse. Then I got so frustrated I did an archive and install. But it still would hang on the blue screen. So being more frustrated I erased my 160 gig hard drive since most of it is on my iBook G4, music, pix etc. Plus i have most of the stuff on my iDisk too and jump drives. I need to know what I can do before I have to drive 45 minutes to the nearest authorized Apple repair and reseller. My only days off to drive down are Wed and Fri. I would like to be able to load Leopard because all the problems started occurring the day Leopard arrived in the mail.. HAHA.

Hi there,
Have you booted off the Install Disk by holding the *d key* down at boot-up, (not the c key), and run the extended Apple HW Test? Some Install disks require holding the Option key at bootup to select the AHT. Some Macs came with separate AHT CDs.
It sounds like either HDD problems, or Logic Board naybe.
Before you try another Install, Erase the HDD with the Zero Data Option...
1. Insert the Mac OS X Install disc that came with your computer, 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. (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 Erase tab.
4. Click the disclosure triangle to the left of the hard drive icon to display the names of your hard disk volumes and partitions.
5. Select your Mac OS X volume, then chose MacOS Extended Journalled.
6. Click Erase & look for Options. choose Zero 1 pass.

Can't get past the Blue Screen during startup

I decided to upgrade the 4/8/08 firmware on my aluminum bluetooth keyboard this afternoon using my mac mini. Shortly after the procedure started, something happened to the keyboard and it could not complete the install. I tried a second time, but again no luck. I then decided to replace the keyboard batteries and try again, but I was no longer able to connect the keyboard to the mini.
I decided to restart the computer and try the whole procedure again. But after the grey screen comes up with the Apple logo, the mini went to the blue screen with the spinning gear, then the mouse appeared in the upper left hand corner, then a little later the gear, then nothing, then the mouse, then the gear... I could never get past this blue screen.
I plugged in a wired keyboard and was able to startup 10.5 using the install DVD, which allowed me to check and repair the permissions and the disk. After a restart, still stuck on the blue screen.
I tried zapping the pram. Still couldn't get past the blue screen.
I was not able to start up in safe mode (is the timing critical for when to hold down the shift key?)
I started up in single user mode and attempted to move the preference files as described here:
http://docs.info.apple.com/article.html?artnum=106464#symp1
but got an error that I did not have the correct permissions. I assume that is because I was trying to save the preference1.old (and preference2.old, etc) files to the root part of my hard drive.
Any suggestions? Does it make sense that upgrading the firmware on a bluetooth keyboard could take down the whole computer???

Disconnect all peripherals from your computer.
Boot from your install disc & run Repair Disk from the utility menu. To use the Install Mac OS X disc, insert the disc, and restart your computer while holding down the C key as it starts up.
Select your language.
Once on the desktop, select Utility in the menu bar.
Select Disk Utility.
Select the disk or volume in the list of disks and volumes, and then click First Aid.
Click Repair Disk.
Restart your computer when done.
Repair permissions after you reach the desktop-http://support.apple.com/kb/HT2963 and restart your computer.

On start up sometimes I get a blue screen and start up hang there

On start up I sometimes get a blue screen and it hangs there the only way to get out of this is to turn the iMac off at the back then when you turn it back on the desk top appears without going through the startup screens. Even had the blue screen when starting in safe mode.

Then run Apple Hardware Test in Extended Mode, it's possible you have a hardware issue. If you still can't locate the issue the next step is taking the machine in for a professional diagnosis at your local Apple Store or AASP.

On boot up my macbook gets hung on the blue screen

On Boot up my MacBook Pro gets hung on the blues screen. I have to close the display let it sit for about a minute and then open it back up. Then the sign in window wil come up. Next I have to wait 5 to 8 minutes after selection of a user name to be able to enter my password.
I just had to restore my OS from Time Machine because it would not boot up.
any suggestions?

If you haven't already purchased a new disk, I would strongly advocate getting an SSD drive to replace the failed hard disk in your machine.
I would recommend nothing but Intel SSDs - they are by far the best-performing ones out there. I have a 240GB Intel 520 - http://www.newegg.com/Product/Product.aspx?Item=N82E16820167086 - in my Late 2011 MacBook Pro with 10.6.8. Downloading, opening multiple tabs while browsing, bootup, shutdown or software install speed, it's an incredible dream. A full install of 10.6 last night was completed in 5 mins and 35 seconds on my machine!
There are also other high-performance SSDs like the Samsung 840 Pro - http://www.newegg.com/Product/Product.aspx?Item=N82E16820147193 - but from my personal experience (installed in a client's office PC), no consumer SSD can best the Intel in performance.
Regarding getting the machine back to a usable state after its drive crash - I recommend doing a clean install of the OS along with all the programs you use, doing an initial sync with Time Machine, booting back to the Mac OS X Install DVD and making a DMG disk image of your new drive to be saved on an external backup hard disk (perhaps your TM drive).
Reason being if your machine screws up in one way or another in the future - be it a misbehaving software update or another disk failure - you can just plop in a new drive, boot with the Install DVD, plug in your external drive and restore the "master" image to your new drive and restarting from it; all your programs will already be there without needing to go through the tedious process of reactivating et cetra. You can then immediately retrieve any missing documents from your TM backup with little hassle since the system was already synced to TM and it will recognize it as the "same" Mac despite the drive change.
Of course, with anything comes pros and cons - and the cons in this case are needing to fiddle around with the command-line interface (Terminal) and some initial fidgeting with external drives. However, it will all be smooth sailing for future disasters once the "master" image for your machine is saved on the drive.

Start-up hangs on a blue screen - any ideas?

My iMac, which is running 10.5.7, is hanging on a blue screen at start-up. Goes through the pale gray Apple screen then cycles between two blue screens, one with the little circular progress bar and the other plain blue. No prior problems.
I've tried unplugging peripherals, reset PRAM, safe mode and repairing disk and disk permissions using install disc, all to no avail. Any suggestions before I try to archive/install?
Update: just found that, with my MacBook connected by FireWire, all my shared info on iMac still visible and fully accessible.
Many thanks!

Already tried that stuff, but thanks for the help. Exhausted all the usual troubleshooting recommendations, and had to resort to archive/instal in the end. Now seems fine, but no wiser as to what happened.

Leopard DVD hangs at the gray screen

Hello,
I've been trying to install Leopard on my computer for the past two weeks, but with no luck. The installation completely hangs at the gray screen that has the apple logo (it hangs BEFORE any menus or dialogs are shown, i.e. before the "installation" even begins). Some people suggested that the media could be bad, so I called Apple and explained the problem to them. They tried to walk me through it, but no luck there either. So, they sent me a replacement DVD, and, well, it stills hangs. I checked/did all of the following:
1. My iBook (early 2004 model) meets the minimum requirements (1.2Ghz PPC G4 processor, 512MB RAM, and 60GB of disk space).
2. My CD/DVD combo drive is in full working order. I've played many CDs and DVDs on it without any trouble.
3. I've tried different ways to boot the DVD: loaded the DVD in Tiger and selected the "Install Mac OS X Leopard" option (which prompted me to reboot), booted the CD directly (by holding C after the chime), and selected the CD explicitly from the boot menu (by holding Option after the chime). None of these methods worked (i.e. it still hangs at the gray screen).
Any ideas what could be wrong? Also, can I somehow put the installer in verbose mode (maybe a key combination to press?) so that I know what the problem exactly is?
Thanks,
Yousef

OK, I managed to install Leopard by creating a disk image of the installation DVD, placing it in its own partition, and setting it as the "statup disk" from system preferences (in Tiger). Everything went fine with the installation except my iBook still hangs. I've booted many times using verbose mode, and it always hangs after the following line is printed:
(Date and Time) localhost mDNSResponder\[22\]: SetDomainSecrets: mDNSKeychainGetSecrets failed error 0 CFArrayRef 0000000
(Safe Boot works just fine)
Thanks,
Yousef

I get the blue screen loop when I try to start my Mac Pro dual-core intel computer. How can I get it to open?

I get the blue screen loop when I try to start my Mac-Pro. How can I get it to boot up all the way? Can anyone advise me?

Which OS X is installed?
Troubleshooting advice can depend on that information.
