Macbook won't boot in any mode

It started playing up last week but I booted it with command s and it's been fine, today it's done the same and I've tried rebooting it with every different key combination I have seen on discussions online and it either just keeps thinking on the apple logo page or goes blue. If I try to boot in safe mode the progress bar never fully finished, it stops halfway and goes to the blues screen. I've not made any changes or updates to the macbook? Model is a1181. Can I get a recovery disk or software disk to reboot it as I don't have one of those either? This is my first mac so I don't know much about them? All I know is I'm deployed in afghan with a broken laptop lol. Ta for your help

He tried booting it in safe mode and from an external drive, neither of which worked. He said that he could hear the hard drive spinning and it didn't sound right (when I held my ear next to it, I couldn't hear anything).
He spent most of the time working in the back room and didn't give me much information. He simply said that I needed to swap out the internal drive and that should fix the problem.
Obviously it didn't, so I have no idea where the problem could really be.
I do know that my drive is bad, because I put it in my mom's macbook (we have the same kind) and it didn't boot in there.
However, I cloned my mom's working drive on my blank ssd and tried putting it in my macbook, but that didn't work either.
The computer won't respond to any commands - it won't even eject the install disk I put in.
I am at a loss as to what to try next, and I can't find a similar situation addressed on any forums.

I have a common problem, I get theese messages every now and then in console:

I have just boot in safe mode. (holding Shift during boot)
but my macbook won't boot in Safe mode. It just freeses with a grey screen for hours and wont boot.
I tried to leave it overnight to boot, but it didn't.
Please help me make my macbook to boot in SafeMode.
my configuration is the following:
MacBookPro8,1
OSX 10.8.2

There is a bug in fsck_hfs that is affecting a bunch of people. Basically as your comptuer starts in safe mode, it runs a file system check (fsck) against your hard drive, it gets to a certain point and... just sits there. No one knows why outside of apple.
Lots of info here, including a way to get around it by tricking the system to think fsck had been run, though the fsck will not be complete so it is not a good solution.

Yosemite install won't boot into any mode

Really sorry if this has been covered before but I spent a good time searching and couldn't find any existing posts with symptoms to the same extent.
I've got a 2008 iMac 27" and have the latest version of Yosemite installed (10.10.1 I guess). I upgraded to Yosemite probably 2-3 weeks ago and everything has been fine. Then yesterday when I woke it up from sleep it effectively froze - no mouse or keyboard input. So I did a reset by holding down the power button, and when I turned it back on it went to the apple logo boot screen with a progress bar that gets to just below 50% and stuck there. I've restarted quite a few times and left it running up to six hours and still it doesn't boot.
Now this is similar to the issue here - OSX Yosemite won't boot after install on mid 2010 iMac - except I am unable to boot into any mode, and the only startup keys accepted are the P-RAM reset. It won't boot into recovery mode (command+R), safe mode (Shift), startup drive select mode (Option), diagnostics mode (D)... nothing
I've booked into a Genius Bar appointment when the Apple stores reopen after Christmas, but I'm hoping that is a last resort and to be honest I'm unsure what they can do for me except to say it's a lost cause.
Are there any suggestions on what could be happening and why it's ignoring the startup modes? I would have suggested the keyboard not being recognised except the P-RAM command works perfectly, so it's obviously seeing it. I'm a little scared that because it won't let me into a boot device menu (which must operate independent of any HDD) then there's an issue ahead of that in the boot sequence, so possibly the motherboard is shot...
Sorry if I seem a little desperate. I had a HDD crash two years ago to the day (great Christmas present Apple) and it kind of puts a dampener on things.
Happy holidays and I'm grateful for any help that anyone can offer

Mid 2011 iMac won't boot in any mode.

Hello,
Last ast week in the middle of a deadline my imac crashed. I was in the middle of a Pro Tools session and the next thing my mouse icon turns into a series of dots and everything freezes. So, I rebooted and since then I haven't been able to get it to boot in any mode.
On booting it gets to about 1/3 through the progress bar and then hangs.
I have tried the following, all steps have not worked:
Safe Mode
Recovery
Internet Recovery
External Mavericks Drive Boot
Resetting NVRam, PRam
I was able to use target disc mode to get my work from my drives. Randomly it booted once after the crash, I was able to run disc utility's repair disc on my system disc, to which it came back with "disc appears to be fine".
I have taken the iMac to my local authorised service centre, but so far it has been a week and they haven't even looked at it yet.
my question is basically, what could it be that is causing my iMac to do this? I was thinking it may be hardware issues.. But I have no clue really?

*Also,
I have tried running hardware test on startup, but nothing happens when I do. Just stays on the gray screen. After it randomly booted and I ran disc utility, it did the same thing. Mouse icon turned into a series of dots in a vertical line, froze, then rebooted.
After resetting the P and NVRam booting in safe mode shows a blue screen with vertical lines and/or shows some debug info on the gray startup screen.
I will post some photos for reference.

MacBook Pro won't boot in any mode

My MacBook Pro was working all fine and dandy until I left it for a week whilst on holiday and when I came back it wouldn't boot. It just sits on a blank grey screen after the apple logo and spinny loading circle. After some research I saw posts about starting the mac up in different modes. Safety mode- sits on a black screen, Recovery mode- sits on a grey screen. After no luck I saw about single user mode. Booted to that and used the fsck command and my hard drive was working fine which brings up the question could it be the logic board. I hope not as I only got this replacement around last December and my apple care has now run out.
Anyone have any ideas or have come across this before. Also I need to backup my files as I can't really afford to lose them, I have a external hd.
Thanks

Hi dbralph,
It sounds like you have been on the right track in troubleshooting this issue. If it is still booting to a grey screen, you may find the troubleshooting steps outlined in the following article helpful (apologies if you have already seen it):
Mac OS X: Gray screen appears during startup
http://support.apple.com/kb/ts2570
Also, if you need to access your files and have access to another computer, you may be able to start your MacBook Pro up in Target Disk Mode to access the hard drive:

My MacBook won't boot into recovery mode after new hard drive installation. Please help!

I just installed a new hard drive. On boot it keeps on going to the flashing folder with a question mark inside.
I was able to format the new hard drive but am unable to boot into recovery mode to install the operating system over the air.
When I hold down Command -R it keeps on taking me to the flashing folder.
Please help!

A new hard drive doesn't have a recovery partition. It's totally blank.You're going to need either your original install discs or a Snow Leopard retail disc from which partition, format and install OS X.

Has Mavericks gone all maverick on my 2010, 27" iMac? Long story, short: Replaced 'bad' HD with identical model (1TB), reloaded apps, + got external 2TB HD. Fan was running high, now machine won't boot in ANY mode.

I have a mid-2010 iMac (27") 2.66 GHz Core i5 (750) with 4GB RAM that I bought second-hand almost three years ago. It worked perfectly...until I 'upgraded' to Mavericks last Fall, & all my trouble began. At first, certain apps started getting kinda wobbly, especially Chrome which was really unstable. Eventually one day on boot-up I got the gray screen/apple logo/spinning wheel/loading bar--and then it would shut down. I got apple care on the phone and we went through a laundry list of various tests and start-up attempts. We reset PRAM, got me into safe mode and eventually hit a point where we were going to have to wipe the HD and start fresh--except I didn't have a back-up (shame on me!). He told me 1) the error code that came up after running disk utitility (?) indicated no problem with HD and that it was software related; and, 2) to take it into Genius Bar, have them backup data and then I could call him back and we'd do the deed and then reinstall with backed-up files. Tried but Geniuses said, "We don't do that" and told my hubby how to. We bought the equipment and prepared to back-up using my son's MacBook Pro. No glory. Nada.
After much back-and-forth with 'geniuses' and guy on phone, we took it to MicroCenter. Their diagnostics said HD is shot--get new one. After pricing everything out we went with iFixit's instructions, and I ordered the identical (I thought) HD for Mac online from manufacturer. We installed it, but had wee problem with LCD temp sensor and so fan ran like crazy. I also bought a 2TB external back-up and did routine back-ups, so I should be good there. I am aware of that third rail on the HD's with sensor but thought I could circumvent that and 'knew' it was really the LCD sensor that was the problem. I was traveling for months all winter/spring so didn't have time to devote to a pesky fan noise. HOWEVER, with increased use being home for several weeks, suddenly we are back to square one it seems. One day the machine shut down and has not rebooted since--about three weeks ago now. Haven't called apple care but tried to reset PRAM and tried to restart using thumb drive where I thought I had saved a copy of Mavericks--didn't work so don't know for sure if it's on there. I opened machine back up and saw that LCD sensor wire was not connected and falling apart. I ordered a new wire which installed tonight with no apparent problems, crossed my fingers and...NADA. Same-o, same-o: gray screen, apple, spinning wheel, loading bar...then it shuts down and goes to black. I have tried to restart with all kinds of codes: reset PRAM, safe mode, hold down option key, hold down Command+R...again, nothing. I even replaced the keyboard batteries. As the progress bar fills up near the end, I hear a little click and whirr, fan running softly, but then it just shuts down. I should mention that the PRAM reset did actually start out like it was working--it shut down/restarted but then the daggone apple/gray scree/spinning wheel/progress bar would kick in again...and then shut down 5-10 minutes later. Any ideas, folks? Please help?

Your internal hard drive is not good.
Your Time Machine drive with your backups on it, if these backups were created using OS X Mavericks version of Time Machine, these will not be accessible by early OS X versions of Time Machine.
Plus, Time Machine stores data and nothing of the OS X system.
Plus, you want to save/retrieve your data that is still on your iMac's internal drive.
So, we can try to get your iMac back to running OS X 10.9 Mavericks.
The most easiest and direct way to do this is to just purchase another external 2 TB hard drive (preferably a fast FireWire 800 external hard drive)
You can use your OS X Snow Leopard install DVD to format this new hard drive as an OS X Extended Format with GUID partition scheme.
Create two partitions on the new external drive one that is big enough for OS X and all applications (say 500 Gbs) and the remaining partition for storage so you can manually copy all your important data ( and maybe your Applications folder, too) from your Mac's internal drive (if it is accessible) to the large partition on this new drive.
Once the drive is formatted using the Disk Utility app that is on your OS X Snow Leopard DVD disc, you can then proceed to install OS X Snow Leopard to this new external drive and now giving you a bootable hard drive that will have a fairly fast, working OS X version your iMac can boot to, now.
Once OS X 10.6 Snow Leopard is install to this new external hard drive, you need to boot to this to get up and running.
Use OS X Software Update feature to get you back to OS X 10.6.8 Snow Leopard so you can regain use of The Mac App Store.
You have two options, now.
You still need to attempt to manually copy over all your important data and applications over to the large storage partition you created on this new external drive.
Once you have done this, you need to search for, purchase, download and install a data cloning app, like CarbonCopyCloner or SuperDuper to be able to clone your new hard drive's system back to your iMac's internal drive once you have resolved/replaced you iMac's Internal hard drive, again, if it is damaged.
If you still want to be able to access your Time Machine Backup drive, you can go ahead and try to re-download OS X 10.9 Mavericks ( you may need to use a Combo Update version from the Mac App Store, now as Mavericks is up to 10.9.5, now. You will upgrade install Mavericks over your new OS X Snow Leopard partition on the new external hard drive.
If, successful, you should be able to access your Time Machine backup at this point.
You will be running your iMac from this external drive until the internal drive is repaired/replaced.
The other idea is if you do not care about your Time Machine backups on the other drive, you can foresake the data on this drive and keep this new external drive , and your iMac, running OS X 10.6.8 Snow Leopard and forget about upgrading to Mavericks, at all, since you had so many issues with it.

MacBook Pro Retina 15" mid-2012 won't boot in clamshell mode with an external display attached

I have a 15" MBPr mid-2012 running OS X 10.10.1. The system won't boot in clamshell mode (power is connected, lid shut) with an external display attached via an Apple Thunderbolt->DVI adapter. it boots fine if the lid is open. It isn't the adapter or the display since my 15" MBPr mid-2014 boots up just fine connected to the same adapter and monitor. And this system used to boot like this just fine some while ago (probably before it was upgraded to Yosemite). I've reset the NVRAM (twice) to no avail.
Has anyone encounter this? Anyone have a solution? Should I try an SMC reset (always a bit nervous about that)? Might it be a driver issue in Yosemite?
Thanks.

OS X Lion 10.8.2 won't boot into recovery mode

Help! OS X Lion 10.8.2 won't boot into recovery mode, I get a grey screen, the apple icon and the spinning symbol...Does anyone have any suggestions?
Have a MacBook Pro (2009) and had no problems until upgrading to LIon from Snow Leopard... thanks!

Hi there - thanks very much for your suggestion, it did reboot eventually but took a long time to get there.
I've have run Disk Utility. After Verifying the disk it said it needed Repairing - so tried doing that and got the message " Error: Utility can't repair this disk. Back up as many of your files as possible, reformat the disk, and restore your backed-up files" I have got Time Machine but haven't backed-up since Dec 12...Can I use "Restore" to copy the MBP HD to an external HD and then re-install Lion?

IMac will not boot from any mode except Target Disk

I have an Early 2008 Penryn iMac 24" MB398LL/A running OS X 10.7.4 (see specs below) that will not boot from ANY mode, It also has several strange vertical bars from top to bottom on the screen. They are about 10 px wide, with some pixels empty and looks a bit like a barcode if you squint at it.
I have tried Safe Boot, Force Boot, DVD Boot, FireWire/USB Boot, and it always gets to the same point. It gets to the apple screen with the spinning gear and then after about 8 seconds it freezes. The only way it works at all is in Target Disk Mode. It pops right up on my Macbook Pro and I was able to grab all my info!
I have run Disc Utilities and Tech Tool on it many times from my MBP and it passes every test.
I reformatted the HD and installed 10.7 again, it still freezes up at the same point.
I have tried using Single User mode and every time have had to run /sbin/fsck -fy twice because it always says the disk is ok but it was modified on the first pass.
I thought maybe it had a bad video card or logic board but and I ran the Apple Hardware Test on many occasions and it always passes. Recently I was told about Loop Mode and just completed running the AHT for just over 30 hours without any errors at all.
UPDATE...
Strange Part… I tried installing Mountain Lion in Target Disk Mode and everything went smoothly. When it restarted on its own the lines on the screen were gone for the moment, but the Mac still freezes up on the spinning gear and immediately restarts on its own. I have run every thing listed above on it and still nothing. Sometimes the lines reappear then in two more starts they are gone.
I did manage to have it start one time got a copy of the the error report (its at the bottom too) The Mac ran for at least 30 minutes with no problems, then the screen went crazy a few seconds and it became unresponsive. The mouse moved but that was all it could do. Now my iMac continually restarts itself, I don't have any more ideas, HELP!

MacBook won't boot when iPod is connected

I have the same problem as described here :
http://discussions.apple.com/message.jspa?messageID=4112865
My MacBook won't boot if my iPod 5G is connected to the USB port.
If I unplug it, it will boot normally.
Does anyone know what could cause that ?

<When iPod is plugged in at startup, the MacBook does not startup; unplugging iPod lets it startup.
yes, it seems that the kernel is not loading
<After resetting the iPod and BEFORE synching it, there is no problem. Any type of synching seems <to make this problem recur.
only syncing music make the problem occur.
the other syncing works ok
<Even if iPod is connected directly to Mac and it is the only USB device connected, the problem still <occurs.
yes
<The iPod and MacBook work fine if iPod is connected after startup.
Yes
<If the iPod is set to NOT mount to the desktop, the problem with startup does not occur.
Yes, but there are some problems in the boot/halt process.
something like "killing all" fails and unmounting /home fails (45) blabla...
and the stopping process takes very very long, about 2 minutes.
thx robert

My Macbook won't boot up because there isn't enough free space for my start up disk. It's now stuck on a blue screen. How am I meant to delete files to free up space if I can't access the computer?

My Macbook won't boot up because there sin't enough free space to run the startup disk. My Macbook now won't go past the blue screen so exactly how am I meant to be able to delete files if I can't access the computer?

Do you have a bootable backup?
What operating system are you running? If OS X 10.6 or lower, boot from your original OS X DVD or a retail OS X DVD and then delete files as needed. Your goal should be to get to 10% of your disk capacity free.
If you have OS X 10.7 Lion or 10.8 Mountain Lion, you don't have many choices in recovery mode (boot holding the command and r keys down).
If you have a FireWire or Thunderbolt connection, you can try target disk mode with another mac.
If none of those work, perhaps your local Apple store can help with a bootable external drive.

Macbook won't boot up - grey screen only

Hi,
I have a core duo MacBook from summer 2007.
All of a sudden the MacBook won't boot up. The battery is fully charged and AC adapter plugged in (same symptoms if not plugged in). The following occurs upon pressing the power button:
1) Start-up chime sounds
2) Can hear hard drive and fans start up
3) Screen turns grey
4) Nothing happens (screen still grey)
Thoughts? I tried resetting PRAM and PMU with no changes.

I have the same problem, just the grey screen and tried
- resetting PRAM (second chime, so this should be OK)
- Safe Mode (just the same)
and pressing Option (or C) to choose the Mac OS X Install Disc gives me the wonderful cursor which can be moved by moving the mouse. No harddisk and even no Install DVD are displayed on the screen.
Also The Apple Hardware Test (by pressing D) doesn't get further than the, now familiar, grey screen.
I pressed the keys with different keyboards, with the original white keyboard and with the aluminium keyboard.
As I've tried everything, I think there's something seriously wrong. Does anybody have some last tips that I can try?

Macbook won't boot up anymore after trying to reformat

So my White Macbook won't boot up anymore after trying to reformat. While trying to install a fresh copy of Snow Leopard, the Macbook just froze and I had to reset. Now, while trying to boot it up, it hangs at a white screen with a folder with a question mark.
My install disk is still in there, so when I try to boot up while holding C, nothing happens. It either goes to the folder with a question mark or the screen stays white. So after that I tried holding option to go to the drives nothing happens. I just see a white screen and a cursor.
I tried resetting PRAM and tried booting in safe mode and everything but to no avail. Everything results in just a white screen or just a folder with a question mark.
Can I do anything before I have to bring it to the Apple Store? The optical drive should work because before I reformatted it, I could see that the disk was in the drive because the icon was in the upper right.

it hangs at a white screen with a folder with a question mark
Startup your Mac while holding down the Option key. That should prompt the Startup Manager window where you can select the startup disk.
A flashing question mark appears when you start your Mac
