Mac mini won't start up. Grey screen with apple just freezes.

Mac mini won't start up. just get a grey screen with the apple and it freezes. Please help.

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 partitirion & use Disk Utility from there to Repair the Disk, then Repair Permissions.

Mac mini won't start - no grey screen

Hi, my mac mini mode A1176 has stopped working. One night it was fine and the next morning it wouldn't talk to me!
The power light was still on but no video output and screen sharing has stoped - I'd left it being controlled from another mac.
It doesn't respond to the keyboard or trackpad but does turn off if you hold the power button down. Pressing the power button again makes the power light come on and the external firewire drive boots up. I can't hear the internal drive start, there is no startup bleep or grey screen with spinny gear. It won't take a cd or dvd either.
I've tried reseting the SMC and the monitor works fine with another computer.
I've searched this and other support sites but can't find a match for these symptoms.
Anyone got any ideas before I start pulling it apart?
Thanks

Depending on the age of your Mac mini it might be able to be repaired if you want to spend the money.
At work we had a first generation Intel Mac Mini, and I had a similar issue. Couldn't do anything with it. I cracked the case, wiggled the connectors, the RAM DIMMs, etc. Eventually just gave up on it, pulled out the hard drive and mounted that in an external USB hard drive chassis. Then migrated that disk to an iMac that ordered shortly thereafter. We got that machine back in 2006, so there was no chance of getting an approval to have it repaired and I wanted to run Lion on my desktop. That first gen Intel iMac was a Core Duo (not Core 2 Duo) and could not be upgraded to Lion. So it worked out for the best.

TS3824 2011 mac mini won't go past white screen with apple logo

My Mac mini won't move past a white screen with apple logo in the center. What should I do?

Hi ..
If you have v10.7 Lion installed, use Lion Recovery to repair the startup disk if necessary, or reinstall the Mac OS X.
If you are running a prior Mac OS X, boot from your install disc, run Disk Utility. The startup disk may need repairing > Using Disk Utility to verify or repair disks
And try Resetting your Mac's PRAM and NVRAM

17 MacBook Pro is not booting up. Won't get passed grey screen with Apple wheel spinning below.

17 MacBook Pro is not booting up. Won't get passed grey screen with Apple wheel spinning below.

You may be having a hardware problem that you cannot resolve on your own. Nevertheless...
...hold down the command and R keys whilst booting to try to get to your Recovery partition. If you can, use Disk Utility to try to Verify your boot drive (usually named "Macintosh HD" unless you've renamed it). If the verification fails, try to repair your hard drive. If everything appears to be OK, restart.
If you can't get into your Recovery partition, your problem is likely hardware related. If so, keep your appointment and see what the Apple techs have to say.

Powerbook won;t go past grey screen with apple logo on start up

Hi
I am getting very stressed, my powerbook g4 won;t go past the grey screen with the apple logo when switched on. I need to sort it ideally without another computer to go through but if that is necessary then I will do it. I have tried the RAM reboot but nothing, there is not even the spinning loading symbol just a grey screen - which it will stay on until I turn it off. Someone please help!!!!!!!!!!!!! Not sure of my OS as I can't turn my comp on, but I am running leopard on it

Welcome!
First, see if you can boot in Safe Mode, holding the Shift key during startup until you see a message about safe mode. Getting a desktop can take longer because Safe Mode forced some disk checking.s
...I am running leopard on it
Then you should have the install disks. They can be used to boot the computer for repair. Insert the DVD and press and hold the "c" key during startup. That will launch the installer BUT you don't want to reinstall yet. Find the install's Utilities menu and launch Disk Utility. From there you can check the hard drive and make some repairs.
I need to sort it ideally without another computer to go through but if that is necessary then I will do it
That would require that your compute work enough to start in FireWire Target Disk Mode. FWTDM lets your hard drive show up on another Mac as if it were an external drive. You can test by starting the computer and holding the "t" key until you get a blue screen with a big yellow FireWire symbol. Looks like this:

I believe FWTDM's code is in firmware and not on the hard drive , so may let yo uaccess the disk form another computer.

Computer won't load past grey screen with Apple logo, even with OS Disc

I turn on my computer and only gets to the grey screen with the Apple logo and idling circle. After a while, it loads a small box telling me to restart, time and time again, no matter how many times I restart. I've tried holding "shift" to go into safe mode, it won't let me.
I believe it's originally a Tiger platform, and right now I think it's running on Leopard.
I just bought a Snow Leopard OS X Disc, and I inserted it and tried to let it load. It gave me the restart box. I held down "c" while starting up, got the restart box.
Held down "option", and selected the "Mac OS X install Disc"; it went back to the grey Apple logo screen to load, and gave me the restart box after several minutes. Repeated that and held down "c" while loading, still gave me the box.
Nothing I do with or without the OS X Disc is making a difference. I cannot load anything on my computer, period.
Can someone please suggest something for me to try?

Well if you do then turn both computers off. Connect a Firewire cable between them. Boot your computer into Target Disk Mode. After the TDM screen appears boot the other computer normally. If your drive is accessible it will show up as a disk icon on the Desktop of the other Mac. You can then access your files and transfer them to another hard drive.
Then open Disk Utility. Your drive should appear in the sidebar list. Select the drive entry (mfgr.'s ID and drive size) then click on the Partition tab in the DU main window. Set the Partition Scheme drop down menu to one. Set the Format type drop down menu to Mac OS Extended, Journaled, then click on the Partition button and wait for the process to complete.
Your drive should now be OK assuming it's not mechanically damaged. Eject the drive from the Desktop as you would eject any removable drive and disconnect the Firewire cable. Shutdown your computer. You can now boot from the installer disc and install OS X.

Macbook Pro won't boot past grey screen with Apple logo and then shuts off

This is a long story...
This morning, I would turn it on and it'd go to the grey screen with the Apple logo for a few seconds and then go to the icon that is a circle with a line through it. After reading online, I was able to boot it up in Safe Mode. I messed around a little bit in system preferences thinking I could fix it on my own, not really knowing what I was doing (I'm a *******). I went to Startup Disk in Preferences. I chose the MAC OS X, xxxx and then clicked the lock to prevent further changes and then clicked restart.
Now when I turn on the macbook, it goes to the grey screen with the Apple logo for at least two-three minutes and then just shuts off. Won't boot into Safe Mode now. Please help. I already tried the Command-Option-P-R keys trick like five times.

If you have a full retail DVD for 10.6 you can boot from that by holding the C key during startup...but you will then be in install mode if that is what you want to do. At least go ahead and see if it will boot ok from the 10.6 disk and then you can decide what you want to do further.
Apple does not have 10.5 for sale anymore from what some other users have said on here so if you want to go that route you will have to find a copy for sale such as from eBay or one of the Mac resellers.
Before taking the machine to someone, try booting from 10.6 and see if that works...that way you can narrow down problems the machine may be having.

Macbook won't boot past grey screen with Apple logo and spinning wheel.

For some reason, after about 1 year and 10 months of owning my Macbook, it decided this morning not to load past the grey screen with the Apple logo and spinning cog/wheel.
I used it for a couple of hours beforehand, and it was working fine. Software Update prompted me of about about 4 or 5 updates; I can't remember exactly what was downloaded, but I think there was a Security Update and iTunes among them. I restarted, left it to install with no errors, but when I logged in, Safari and iTunes were running incredibly slowly. I also noticed that the volume keys weren't responding, as well as the power key to bring up the "Sleep, Restart, Shutdown, etc" dialog box. I forced shutdown, hoping a restart would solve my problem, and that's when my troubles started. I originally just left it, but after about an hour the wretched thing was still spinning.
So far, I have done a number of troubleshooting tips on a variety of websites. I have tried taking the battery out and holding down power for 5 seconds, resetting the PRAM with option, cmd, p & r, and holding down power until the sleep light flashes rapidly and the computer lets out a large "BOOOP".
I have booted off my Leopard install disk with both option and c, repaired the hard drive a number of times, with there being no errors whatsoever. I have tried repairing permissions, but everything seems to freeze up, except the mouse.
For some reason my computer will not boot into safe mode, either, and holding cmd & s at startup doesn't get me to the stage where I can enter commands with the keyboard.
Unfortunately, because of my puny 60GB hard drive, I only have 1GB of free space left and cannot reinstall Leopard without wiping my hard drive.
I would greatly appreciate it if anyone could assist me with this unfortunate dilemma. It's such a shame that my computer has been fantastic for so long and now decides to play up. (Maybe it's just Apple trying to get me to buy a new 2.4Ghz aluminium Macbook sooner than I was planning...)
Thanks very much.

Hi ds,
Sorry to hear you're having such trouble!
Unfortunately, the best thing you can do at this point is reinstall Leopard (and then attempt to install the combo updater, too). If you don't have a backup of your machine, you could boot it into Target Disk Mode (by holding down T at startup) and then attach it via FireWire to another computer to salvage your files.
I recently had to repair a machine with this exact same problem, and after messing around with that for several hours, I'd have to say that I think that an Erase and Install is the way to go. If you then migrate over your user data and start having troubles, you at least know where the problem lies. I suspect, though, that having a clean machine with all of the new updates applied will be the end of the issue.
Sorry to be the bearer of bad news. There are a few other things you could try first; you could, for example, manually download the relevant combo updater from Apple's website and attempt to install it to your damaged machine while it's in Target Disk Mode. If you have a copy of Disk Warrior, that too is certainly worth a shot (and in some cases may be the saving grace). In my experience, though, a failure of this magnitude isn't easy to resolve.
Hope that helps.

IMac 24 won't start up, grey screen with progress bar, then shuts off

My computer froze all my applications yesterday. When I went to restart it a grey screen came up with the progress bar at the bottom. It would advance about 1/3 and then the progress bar would start over. It would advance about 1/3 again then the computer shuts off. It does the same thing trying to start it up in safe mode. I started it with my snow leopard disk and it will allow me to restore the computer with time machine (which we have), but I wasn't sure if I should try something else before that. Any help would be greatly appreciated. Many thanks.

Hello:
I would try restoring as an approach to eliminating some software glitch. However, you might also have a hardware problem (not good news).

My G5 won't start beyond grey screen

Hi Folks,
My G5 won't start beyond grey screen with the logo on it. The fans simply get louder and louder.
It acts as our server and the raid drive on it had been having privileges problems. One person on another forum suggested I run Disc Utility to repair permissions. I did so, there were a couple of minor permissions fixed. After that, the Mac would not re-boot.
I got the DVD door open and ran Disk Warrior on the drive, the files and the hardware. It claimed to repair a few minor issues and there were no problems with the hardware. It still wouldn't boot, so I reset the SMU. ?Still no start, so I reset the PRAM. Still the same.
Any ideas?
G5, OSX 10.5.6, 6 GB ram, approximately 100 GB free on system drive, over 800 GB free on RAID.

I'm having the same problem though I'm running 10.4.11. After getting to about the point you are at did an "Archive and Install" but after about a day of working fine, it had a kernal panic and I couldn't boot past the gray screen again. I took it to my local Apple Store and they ran 2 hours of diagnostics w/o finding anything wrong. They told me to do an "Erase and Install." That is where I am at now because I can't get the machine to boot from my 10.3.5 Install CD--it hangs at the black screen when I try to boot from the CD by holding down "C" at boot. This is the original system software that came with the machine at purchase.
There are many posts out there about bad RAM causing these kinds of problems. You might want to search around for those posts.
Good luck and I'm going to watch this thread hoping that someone will have a suggestion that will help me too.

My Mac Mini won't start. The Power light blinks continusly (not pulses)

My New Mac Mini won't start up. I bought it online from J&R a week ago. My monitor says "no input detected" and the power light blinks. I recently fed it the gray mac os x install disk one, which it won't give back. Holding the mouse button when it turns on doesn't have any effect. So now i can't put a disk in or start it up.

Welcome to the Apple discussions.
No video with the power light blinking once per second means either bad or no memory. See this Apple note: http://docs.info.apple.com/article.html?artnum=303083 . Specifically, below is from that note:
If the computer detects no SDRAM (Synchronous Dynamic Random Access Memory, also referred to as RAM) or the RAM installed does not meet the appropriate specifications, the screen will remain black but the power LED on the front of the computer will blink once per second to signal the error. This error condition may be due to physically damaged RAM, installing the incorrect type of RAM, or not having RAM installed.
Has it ever worked since you got it? If not, you should call J&R and tell them they sent a dead on arrival system, and ask for a replacement (ask them to send a will call tag or prepaid label to send the non-working machine back).

My mac mini won't start up!

My mac mini won't start up but it will turn on, staying at the gray apple logo screen and nothing else.
I came home yesterday and it wouldn't 'wake up' from 'sleep' mode so I turned it off and tried to turn it back on. There's a netflix cd in there that I also can't get out. My friend suggested i slip a piece of paper in there and that it will eject, but this isn't working (maybe I'm doing this wrong?)
help! thanks.

I have the same problem. In addition, the same happens when attempting to boot from a DVD. I was able to boot it up in Target Disc Mode, and even erase the internal HD entirely, but I still cannot boot from DVD to reinstall the OS. I have tried the SMC reset, but to no avail. Also, while I can reset the PRAM, I cannot reset the Open Firmware. Any suggestions?

Mac Mini won't start and constantly makes disc ejecting noise

My Mac Mini won't start. It was working fine, then just locked up and won't start again. When I push the start button it just makes this repeated disc ejecting noise from the DVD drive. It doesn't make the chime noise or display anything on the monitor. I've disconnected the optical drive, but it didn't help. Then it just doesn't start at all. I thought that if I would disconnect the optical drive, that it would ignore it and just boot off the hard drive, but nothing happened. The power light comes on. Then, if I hold down the power button for 10 seconds it shuts down. The fan operates. It just never attempts to boot up. I can't put in a system DVD because the optical drive is just in eternal eject mode.
If you have any suggestions let me know. Thanks.

I have the same situation.
I think the drive thinks it has a disc to eject or part of the mechanism is stuck and can't return to it's resting position. I was going to disconnect as you tried but now I think I'll try to disassemble the drive to see if there might be some debris jamming things up.
Please let me know if you solve the problem.

Mac Mini won't start after installing OS X 10.6.3

My Mac Mini won't start after installing Mac OS X Snow Leopard 10.6.3. When I turn it on, the Apple logo appears and the initialization line starts to fill, but it suddenly stops. It does that again and stops at the same point, but this time it shuts down. What should I do?

If you are coming from 10.5.8, hopefully you backed up your important data first. Your mini will need at minimum, 1 GB of RAM to install Snow Leopard and at least 5 GB of storage remaining on your boot drive.
I treat 10.6.3 as a fresh, full install over a 10.5.8 system. That means I choose Disk Utility from the Installer's menu and repartition the boot drive as a single partition, Mac OS X Extended (Journaled) format, and use the GUID partition scheme from the options button. At this point, while still in Disk Utility, I would verify the drive under First Aid.
Then I turn the installer loose, and reboot into a working 10.6.3 system, ready for the software updates that take the machine to 10.6.8.
So, following the above guidelines, reinstall 10.6.3.
