My Mac pro will not boot. it gets stuck on the grey screen.

My Mac pro will not boot. it gets stuck on the grey screen. What can I do?

Mac OS X: Gray screen appears during startup
If using 10.7 or later, the Installer/Utilities DVD has been replaced with a special emergency partition on the Hard drive called "Recovery_HD"

Mac Pro will not start-up.

My Mac Pro will reach the start up screen: Apple logo spinning start up indicator. Then I see a blue screen then a gray screen followed by gray. The multi colored computer busy indicator will appear folloewd by nothing. Would the problem be a faulty processor? Any suggestions?

I spoke to soon...after installing the MAcOSX Snow Leopard software I restarted with no problem. Once I removed the dvd the computer froze! After a restart the drive refused to boot. This time a dark screen. I was able to restart via safe boot and currently downloading updates.

Mac Pro: Will not Start, Help !!!

I really have no idea what to do, when I start my Mac Pro, I hear the tone but I just get a gray screen and it does not progress to start up, I thought about re-staring it from the OS disc but the DVD Rom does not respond. Any ideas ?

Run Disk Warrior from another boot drive.
If not that, try booting into single user mode and running FSCK.
Boot in verbose mode and see what is happening.
I would not use 10.5.0 DVD, except to install OS X on a new drive.
Use SuperDuper to clone your system when it is working and then put that away, ie, keep that on FireWire drive for emergency only.
run Apple Hardware Test if you want to rule out hardware.
disconnect 3rd party devices and even suspect USB cables, try using another keyboard.
Pull your existing boot drive and put in a new drive and have your DVD at the ready even.
A corrupt journal is harder to repair or overcome.
You don't say if you have had power outage, crash or freeze, or loss of power (I think most users recognize the need for UPS even if they never worry about outages but just to prevent damage by surge or something).
Do you have too much equipment running off the same circuit for it to handle? easy to do.
In short, all the normal routines for diagnosing and repairing a failing system or boot drive.

Mac Pro will not start up. Firmware or graphics problem?

A really weird thing happened to my MacPro 1,1. It has been working fine for the last 5 years until today when I was running Parallels and suddenly the screen got those thin, horizontal, wavy, purple lines all over the place and cursor turned into a beachball. I tried to Force Quit Parallels but it didn't work. I had to hold power button to force the computer to shut down.
I am running 10.6.8 and just yesterday I installed some updates but these were minor: Safari, iTunes, Java. The computer worked fine after those have been installed.
Now the scary thing - the computer does not start up properly. When I press the power button I hear the chime but then I see the grey Apple logo with those purple, wavy lines in it. The computer seems to find the system on the hard drive but when it gets to the login screen it doesn't display the login window or the background properly. Instead I get just a plain grey color with a cursor (arrow) that moments later turns into a beachball.
I unplugged everything to bare minimum and tried to start it up from Snow Leopard CD. It finds the CD but the same thing happens - I don't see the CD installation menu, just a blank grey screen.
This makes me think: either the graphics card died (GeForce 7300GT) or it is some OpenFirmware problem.
I removed the card from its slot, blew off some dust and reset it. No change. I tried resetting SMC as well (Even though the instructions are a bit weird: unplug power, wait, plug it back in, wait, press power). I do have non-Apple RAM installed (6GB total) but it doesn't seem to be RAM issue - all status LEDs on both riser cards just blink red briefly during power up.
Should I plan a trip to the Genius Bar or do I own now a very expensive paperweight?
Any ideas? I would greatly appreciate your help.

I found your thread very helpful. I have a 2009 mac pro 3,1 that seems to be doing similar things. It was working fine then occasionally the screen would flicker and then freeze the system. had to power off to get out of it. Now it won't boot. I get purple and white vertical lines and the apple with the pinwheel. the pinwheel stops after a while and thats it. i tried booting from the cd and get to the harware test but the screen is split left and right. really unreadable. i suspect the graphics card (geforce ) so i tried booting without the card installed. i believe it still did not complete the boot. my question is should i be able to boot without a graphics card installed? any thoughts or advice would be appreciated.

Mac Pro will not start; shuts down after 1 second

Over the past several weeks our Mac Pro got finicky about starting up. It would get partway through the boot (apple logo & spinning wheel) but then suddenly shut down.
Today it stopped getting that far. On pressing the power button I get at most 1 second of activity and then it shuts down.
Did the supposed SMC reset procedure (which is merely to unplug the power cord for a while) with no luck.
Cannot get CD tray to open, nor to start in safemode with Shift.
This seems to differ slightly from symptoms others have reported. The most relevant discussions are archived, of course with no solution from Apple.
Anyone have an alternative approach other than 'take it to Apple'? (Of course, Applecare expired July 23; they time these breakdowns well.)

The reality is the following: nobody knows nothing regarding a solution, that is not the exchange of logic board. Apple Computer doesn't accept that is a serial problem to give us a recall , I've reading many people saying a lot of ******** and nobody gives the true solution, that until now is to exchange logic board . I want a solution that no envolves exchange of logic board .
PS1: I have 8 MacPros early 2008 and have exchanged 3 logic boards and have others with the same problem , and I don't want to give more money for an error of Apple Computer . You know that after long time , Apple accept that graphics adapter of Mac Pro early 2008 had problems and now (after july) is promoting a recall . We have to have this for logic board too . When I talk with them , they say that nobody related this problem before . It's impossible . It's a war and we have to win .
As I have 8 Mac Pros (same model) and I have exchanged 3 logic boards , I've tested every parts of the others and I'm sure that the problem is with logic board (no power supply , no processor , no graphic adapter , no Mac OS version , no memory , no eletrical issue , no UPS problem - Apple doesn't recomend any UPS) . I have lost much time , doing all the possible tests , with system , without system , with 17 , 20 , 24 and 26 degree Celsius , all possibilities and no solutions , except exchange logic board .
PS2 : When one Mac Pro was under garantee , I exchanged a logic board and only two months after , I had to exchange again , because I had the same problem .

New Mac Pro will not start

Hi,
After doing the last update from apple my Mac Pro (late 2013) won't start up.
I installed the update this morning and every thing was working fine. After (ironically enough playing watch dogs) my Mac Pro went to sleep and never woke up. I have fanatically tried everything in my capacity to make it go on again without any result.
The lights in the back goes on but there is no chime or fan noise from the mac. The screens does not go on either.
I have tried to unplug the screens and tried every configuration possible with screens and without. Keyboard and no keyboard.
But the only result I get is the ligths in the back going up, and then down again...
I need help!

I think it is plugged in since the OP said "The lights in the back goes on"

My Mac Pro will not start

When attempting to power up the computer the light above the power button just flashes rapidly and nothing happens. It was up and running fine in the morning and I powered it down because we having strong storms pass thru the area, and then that evening when all had passed I attempted to turn it back on and nothing. I really need to figure this out since I do a lot of freelance work from home. What can I do?

You should already be using a UPS of 1500VA to protect your equipment.
Even if off but still connected to power you aren't and I would not rely on a surge protector, at least not unless it was warranted and was in the $70+ range, half the price of a good UPS able to maintain a Mac Pro. If you want to be able to work through a power brown out or outage, you can even get into add'l battery packs that daisy chain.,
Try unplugging again, all cables, hitting power button for 10 seconds, then retry.

Mac Pro will not start up. Screen keeps popping up telling me to restart.

I was just using the computer and a box popped up telling me " you need to restart your computer. hold down the power button for several seconds or press the restart button". I restart and it still pops up. I unplugged everything and tried again several times and it still happens. I also tried another partition on another hard drive and that says the same thing.
Thank you for any help.

You can't use the keyboard at all ??
Tried booting in OS X Recovery?

Mac Pro will not start

Was using emails then suddenly the screen crashed restarted only to have apple logo and timer showing any help please

Are you getting screens like this?
If you are then your Mac is booting from either over the internet, first image, or from the built in Recovery HD partition on the drive. Both, either, are not a good sign for the health of your hard drive. For either to load automatically when you start your Mac means the hardware can't find a valid install of OS X on the internal drive. If you are getting the Online Internet version, that is where you will see a timer and the fist iomage I posted, means the internal drive is not functioning at all and can't evenm load from the built in Recovery HD partition.
From that Mac OS X Utilities screen open Disk Utility and see if the internal drive is even being seen.
It would be an entry similar to this, the top most entry on the left side.

MacBook Pro will not start up, get start up chime but screen does not light up. Any help?

Upon start up I hear optical drive checked, then get a start up chime but the screen does not light up. I have shut down by holding down power butto for 10 seconds also pulled battery and A/C power.

I had this same issue but after a new hard drive/ram install.
What solved the issue - and I hope this helps someone else who has the same problem:
1). Install new hard drive (with or without osx pre installed) or leave old one in in your case.
2). Remove all ram
3). Power on and wait 1 minute
4). Hold power button until it turns off
5). Install ram
6). Power back on
7). BOOM! It works again.

2006 mac pro will not start up

I had my macpro in storage for quite sometime. I finally got it back and tried to power up but all that happend was some fan noise and button light up for a second and dead. Please help.

A dead logic-board battery can cause a boot failure. See the user manual for replacement instructions. It's also possible that the hard drive has failed.

2009 Mac Pro will not boot up under Windows

I have an Early 2009 Mac Pro system (Mac Pro 4,1) and I've had this system for 3 years already and have been working under OS X with this system ever since I purchased it.
However, when I tried to boot off my Windows disk, something very interesting happens. The Mac Pro WILL NOT boot up off the Windows disk or a known working Windows partition if two monitors are connected. Upon holding down the option key and selecting the Windows partition, I will get a black screen on one monitor (the one connected via Mini Displayport) and the other screen receives no signal and will enter standby and the system is halted. It does not respond to keystrokes, there is no hard drive activity, no measured power increase on the UPS, no apparent network activity, nothing. The only way to exit this scenario (from what I can tell) is to power off the machine, disconnect the display on DVI, power on the machine again, select the Windows partition wait for the system to reach the login window and reconnect the DVI monitor (at which time Windows recognizes it immediately and the system works fine again).
My question to the community is, does anybody know why this is happening and is there a known fix for this? Quite frankly, having to disconnect a monitor just to restart is very tedious and frustrating.
I have two Samsung P2350 monitors attached to an ATI Radeon HD 4870 (512MB, from Apple). One is monitor is connected via directly DVI and the other is using a Mini Displayport to DVI adapter. Both monitors work fine under OS X with no issue. At first, I thought that this may be a driver issue on the Windows side and after installing all the latest updates and drivers the issue is still apparent. From what I can tell, this doesn't seem like a software issue but rather a firmware or EFI issue as this happens before Windows even loads.
If anyone knows of a fix or what to do in this situation, or if you are also having this issue, I would love to hear your input!
Thank you!
For the record, I am running all the latest software builds on the OS X side (10.7.4, not that it would really matter at this point). I have also disconnected all unnecessary equipment in a trial and error scenario but the results are still the same.
The system passes all ASD testing.
The full specification of the computer and all connected equipment are as follows:
2009 Mac Pro (4,1) 8-Core
2x Intel Xeon Nehalem 2.66GHz Quad-Core CPUs
16GB DDR3 ECC 1066MHz RAM (Apple Branded)
Two OWC 120GB SSDs (One for OS X, the other for Windows 7 x64) - These are in place of my optical drives.
4x 2TB WD Black Hard drives for storage.
Two Samsung P2350 Monitors connected via DVI. (One using a Mini Displayport to DVI adapter).

In Windows I am using the latest (12.4) Catalyst Software Suite, 64 bit of course, downloaded directly from AMD's site after installing the drivers from Boot Camp.
As for installing Windows I used an original (not burned) installation media (Disk is in a pristine condition). And yes, Windows is fine, the problem just seems to be getting the system to boot up Windows with that second monitor. However if the "problem monitor" is disconnected the system boots fine 100% of the time and connecting it later after booting the system will still operate properly.
For the sake of arguement I swapped monitor cables and connected the "second" monitor to the mini displayport adapter to verify that it wasn't a cabling issue and I'm still yielding the same issues.
As for GPU testing, I've played games (Crysis, Grand Theft Auto IV, Battlefield 3, etc.) and I've had no issues with the card or stability.
You would think that Apple would try to find a fix for this, especially considering the caliber of this machine.

My MacBook Pro will not start up after entering correct password.

My MacBook Pro will not start up after entering password. Circle with an X in it and 'cancel' below it is on bottom of screen. When clicking on cancel, nothing happens. This just started last night.

Hi MJTOOTS,
Since you are getting to the login screen, it is booting past the "gray screen" phase, so try the steps in this article, like a Safe Boot.
