Mac Mini Intel boots to blue screen and gets stuck

Mac Mini running 10.6 Intel won't boot up. I get the chime, then the apple logo, then a blue screen, then nothing but the small rotating circle, which appears and disappears about every 5 seconds (not the color wheel, but the one that just looks like hands on a clock turning.)
Per apple online help, tried starting up in Safe mode. Same result. No boot. Just blue.
Per apple help, I started up in Sinlge User mode and ran Fsck from command line (I don't have the install disk). First run of Fsck said FILE SYSTEM WAS MODFIFED. Ran it again, per apple help. Second time, said volume appeared to be OK. Typed "reboot". Same result. No boot, just blue screen and rotating circle.
Not sure what else to try. Any help?
Thanks

Sometimes PRAM seems to retain info from a previous startup disk error condition. There is a small chance that resetting the PRAM might help.
You can get a replacement for your original OS X install DVD and any bundled apps from AppleCare (1-800-275-2273) for a shipping and handling fee. You will need to provide your Mac's serial number so they can send the correct DVD(s) for your specific model.

Boots to blue screen and won't load os10

when i turn on my computer, it boots only to a blue screen and no farther.
there is the "whirly gig" things that goes around on the blue screen, but it wont load the OS ..........any helps is appreciated!

I'm in pretty much the same boat...
I left a classroom eMac running a bunch of updates. When I came back and hit the restart button, it goes through the grey screen with the apple and then stops at the blue screen. Sometimes with a cursor in the upper left corner, sometimes with the little spinning gear, sometimes both, sometimes neither.
When I boot verbose mode, it launches loginwindow, then does 2 lines of network startup, then stops. Which makes sense -- because the blue screen is supposed to be showing loginwindow.
I have already:
-- run fsck when booted into single-user mode. It's clean now, but the first time I did it there were errors that were fixed.
-- run disk utility and repaired permissions. Again, the first time there was repair work to be done, and now it's clean.
-- zapped the pram.
-- tried to boot in safe mode (by hitting the shift key right after the startup tones and holding it down until the blue screen comes up -- which comes up without the loginwindow in safe mode.)
Is there anything else to try before a reinstall?
This is a lab computer, so I'm not sure whether to do an archive/install, or to do a clean install, run migration assistant from another machine, and then fix the machine name. The one time I tried archive/install I ended up with a machine which it's impossible to install print drivers on. (I keep installing the driver over and over, but it never appears on the list of printers in the add printers panel.)
thanks for any help!

Mac Pro is booting to blue screen after installing a new Optical Drive

I am trying to install a new Pioneer 115D Optical Drive in the 2nd Drive Bay. After installation I turned back on my computer and it did not boot. I got to the blue screen and the computer just hung there. Any suggestions on what went wrong? I have read something about switching to cable select how might I go about doing that? Also Someone suggested to remove the drive lip. Does that need to be done before installation? I watched the OWC video and followed the instructions there but there was no mention about removing the lip or using Cable Select. Thanks for you help.

You have to remove the tray lip before putting the drive in the computer

When you reinstall the drive holder, make sure it doesn't slice or pinch any of the cables.

MBA logs-in gets to desktop screen and gets stuck with a spinning wheel...

(I am not sure if this is the right thread for this -- MacBook Air 2009 version)
I can turn on, boot and get to the login window (personal accounts and guest account) and when I log in I get to the desktop and get stuck there with a spinning rainbow wheel for long periods of time till I force-shut-down.
I tried booting is Safe Mode and that seems to work perfectly. I have the computer running in Safe Mode now.
How do I recover it to boot normally? I appreciate your helpful responses in advance!

You have to hold down Shift after you power up your computer. Here's a detailed instruction from apple.

hope that helps you... but my problem still persists.

Mac Mini just boots to grey screen - help!

My trusted mac mini a1176 (intel 1.66GHz) has always worked fine but now it just has a grey screen when it starts. There is no chime, and if I leave it long enough a picture of a file with a ? in it appears.
The events leading up to this could have an effect, I am not sure. The original hard drive had a mac and a PC division. I took this drive out 6 months ago and fitted a larger one. This larger one had a carbon copy of the mac part of the original drive made on it. I did not put the PC division on it. All worked fine since. Today I wanted to boot up the PC partition on the original drive so I put the old drive in a USB enclosure, plugged it in and then in settings chose to boot from the PC part of this drive. This is the last thing useful the mini did. It just went to grey screen on restart. So then unplugged the external drive, still no boot. Since then I have tried.
Pressing differen buttons on restart
Putting leopard instal disk in drive ( this is he os I am using)
Disassemble mini and put he original disk back in
SMC reset
Take out extra ram
Disconnected every other peripheral.
I use a apple wired keyboard
A dell mouse (I have a Bluetooth apple one)
Any suggested next steps would be warmly appreciated? Would the logic board just go like that? It seams a bit of a coincidence!
Thanks and sorry for he spelling, this is from my iPhone.

Here is YouTube video of what the screen is now doing.

Mac Mini Intel - no chime, no beep and no picture - fix?

I have Mac Mini Core 2 Duo 1.83GHz, with Intel GMA950 onboard -graphics. Problem is that it powers on but there is no chime, no beeps and most importantly no video. Pressing and holding power button for a while does turn the machine off. Processor and chipset are heating. The light on my USB-mouse blinks when I power on the machine and also if I disconnect and then reconnect the mouse while the computer is powered on. Optical drive does not make any sounds altought I don't know if it's normal for this model, when I had iMac G5 it did make some noise when powering it on. I cannot reset SMC, powering on the machine with power button still pressed for several seconds does not do anything, it should make the fan to run maximum and probably couple beeps. I have able to cause fans to rev. up by pressing the power button and then connecting power cord but this is not the way it's meant to be done.
It is not ram issue, tested with fully working ram and also the ram that was installed in Mini worked on this machine I am now using. I have not tested with another processor, Mini's processor would fit this laptop I am now using so I could later test the processor itself.
What I want to know is that if you have faced similar problems, were you able to fix the motherboard and if so how did you do it? Keep in mind that replacing the logic board is not a way to fix anything since you are _replacing_ the faulty one completedly. I have fixed couple laptops with heat gun but they have always contained Nvidia and ATI -chips which as far as I know tend to heat and break solder much more often than Intel's chips.
So, any ideas?

Slow boot after blue screen and system restore

I did the updates (Security 2008-002, Safari 3.1 and others) in Software Updates and then could not get past the blue screen. Tried all the advice on these boards but none worked. So I used Time Machine to restore the system. It worked except that now the booting process pauses (on a blue screen) for about 5 minutes. Then the process completes and everything appears to be fine.
However, this delayed booting does not seem right and never happened before.
Anything I can do?

What kind of incompatibility issues?
How far does the xp installation get?
What do you mean by 'uninstalling the vista bootloader'?
It seems very unusual that you can't boot from the CD anymore. Maybe double check the boot priority again, or have CD as the only boot option?
I can make XP BSOD and Reboot on my V200 by setting the SATA mode to AHCI. *no floppy = no F6 driver installation
I can't recall how VISTA reacted to setting SATA to AHCI.
Let me know how it turns out.

My Mac won't boot past white screen and startup keys won't work

Hello. I have an iMac not sure what year.
So about a year ago it froze and wouldn't restart, so I neglected it for a year. Now that this my only fixable Mac I have been researching to fix it. I was able to boot into safe mode about a week ago for a little bit but then it froze again. Ever since then none of the startup keys work, even resetting the PRAM, I heard the second ding and then it just brings up the cursor on the white screen with no disk options.
I have an external disk drive connected to the USB I'd like to boot my Mountain Lion from but since the start up keys don't work I don't know how to do that.
Any help would be incredible, I do not care about saving anything from the computer I just want it to work. I hate dealing with the "geniuses" so that's not an option.
Thanks

When you hear the startup tone hold down the Option key and you should be able to boot into the Recovery Partition if you have Lion, Mt. Lion or Mavericks on the internal HD. If even the Option key does not work then your keyboard may have dead batteries or be defective and in need of replacement.
If you have ML on the EHD as a bootable clone then you should be able to boot from it.
My best guess is you have a failed HD though, my advice is to take it in for professional diagnosis to your local Apple Store or AASP and get a quote on what is wrong then decide how you want to proceed.

Mac mini (intel) frequently shutting itself down and restarting.

My mac mini has started to immediately power down and restart on its own. I have been using different apps and even just while in the finder deleting old files and reorganizing. I tried a safe boot (holding down shift) and after that I had no audio!? after another restart (regular) it crashed again...I fear that i wont even be able to finish typing this... These crashes are really just the computer shutting down with no notice and resarting on its own... What else can I do here?

Here is what you inquired about my system.
1.25gb 667mhz DDR2 SDRAM (self installed)
I run basic mac apps plus Adobe creative suite 2, quicktime pro, and recently downloaded the 30 day trial of Aperture...
most of the files I have from the older PPC I used to have are on an external HD pictures and my music library.
The Mac mini was new when purchased
devices connected are: linksys 4-port router, D-Link cable modem, Klipsch speakers, a Lexar multi-card reader, Lacie 250GB external firewire drive, 20" Apple cinema display, apple wireless keyboard but a usb mouse (wireless mouse is a battery sucker!), occasionally I attach a panasonic PV-GS300 camcorder - but this has not been attached for weeks and the problem is newer than that.

Mac pro no boot sound, black screen and loud fans

Hi everyone,
I've had problems with my Mac for a while now. First of all, it indicated ram problems with 2 beeps. I later fixed this by moving and changing around modules. It was solved, but now a new problem. The Mac seems to turn on, making its iconic sound for startup, but the screen remains black. After about a half to one minute, the fans go crazy and I have to shut it off. I've tried a few things like holding shift or alt, but that doesn't work as it doesn't even display a white screen.
I need to know what to do and I don't really have the time to buy new parts right now. I'm really a windows based pc fixer by the way so I'm new to fixing macs.
Thanks in advance.

Ah OK, a PowerMac G5.
Have you blown the dust out lately?
Boot off your *original* G5 Install Disk while holding down Option/alt key to select AHT, then run the extended Apple Hardware Test.
If you're sure the RAM is good, try the Hair Dryer trick...

I have an ibook g4 that boots to blue screen and hangs. Safe mode will boot but hangs after log in. I have reset PRAM, NVRAM, and the PMU. Booted from Diskwarrior and rebuilt and tested the HD, working properly. Boot from Tiger dvd shows images? no text

The tiger install dvd boots only to show an image of what looks to be two steps, not sure what its showing me.. possibly inserting RAM? Anyone have any ideas? Thanks in advance.

Could you get a picture of the screen, load that into your working computer,
and post it into a reply here? There are a few kinds of situations where a
similiar display of that sort may appear.
Given the G4 iBook PPC (which model) is a bit dated now, one has to
assume you have the original 'install-restore' DVD it came with, new.
What was or wasn't it doing, before you chose to try to boot Tiger DVD?
Do you have a second Mac, one w/ FireWire ports; maybe Thunderbolt?
It may be possible to further look into the ailing iBook G4 via FireWire
from a second Mac, and attempt to investigate, or save old data to some
external drive, USB Flash; in case you need to totally wipe the HDD.
An image of the iBook screen may be helpful. Someone else with recent
troubleshooting or extensive use of iBook portables (or other OS X issue)
that presents such a screen instead of a normal progress screen, may
have an immediate idea. Without an image, I am not venturing a guess.
What key did you hold down while trying to boot the computer from DVD?
One set of keys can get you a Startup Manager. Among other options.

Firmware Updates on Mac Mini Intel

I have a mac mini intel. Two firmware updates come up via Software Update:
- Mac mini SMC Firmware Update version 1.0
- Mac mini EFI Firmware Update version 1.1
I have tried to install both of these individually several times. Each time, after I double click on the icon in the Utilities folder I enter my password and choose "shut down". Each time, the system starts the process and never really shuts down. Instead, it hangs on my desktop screen. Eventually, I push the power button. Then, I hold the button down like the instructions say. There is a sound and then it reboots a second time and returns to the login.
The problem is that when I log back in, it says the update has not installed!
I'm using the original Mac Mini Intel (the higher cost version) and the OS is totally updated. I need to update the firmware so that my bluetooth headset will work properly.
Any suggestions?

I wonder if Nokia are planning to release a "over-the-air" update for this phone? It's a pain that the update process requires such particular software.
I believe v4 of the firmware is downloadable via OTA. It may be network/firmware dependant though. It does mean you'll have to pop along to the local Nokia shop for this update or follow the instructions above.

Hi,
Have you tried some of these? http://support.apple.com/kb/ht1533
The first things I would try would be to press shift during start up, this will boot into safe mode.
I think you'll need to purchase a copy of Snow Leopard to re-install the OS.
There's another couple of suggestions here; http://support.apple.com/kb/TS1417 where you can boot into single user mode and look at repairing disk permissions if that's the problem.
I would hope that if you could boot into safe mode or single user mode, then that may automatically rectify your current issue. If not, then I'm pretty certain that a fresh install will be the ultimate answer.

Mac Mini (Intel) and WinXP/Remotedesktop

Hello
I try to run my mac mini (intel) without a screen and without a keyboard using Microsoft Remotedesktop.
Unforunatelly the mac mini will not boot, if it is not connected to a keyboard and a screen.
Running under Tiger the mac mini will boot without connecting a screen and keyboard. Further I can use a VNC-Server and VNC-Client in order to operate by remote control.
Has anyone of you an idea how I can solve my mac mini boot problem?
