Mac Pro light blinks on boot up... screen blank

Ever since I installed Boot Camp on my Mac Pro, I get a blinking light above the power button on boot ups. This mostly happens after reboots, and I have to leave my computer alone for several hours before I try again. Only after letting the computer sit turned off for a while will it then boot up with out a blinking light error.
Has anyone else had this problem or know how to fix it? It doesn't blink as fast as when you update your firmware.... it's a slower blink on every second. It's very frusterating and I have no idea what's going on. Any help would be greatly appreciated.
Thank you,

First thing to try is resetting your SMC:
http://docs.info.apple.com/article.html?artnum=304123
Also, your PRAM:
http://docs.info.apple.com/article.html?artnum=2238
Additionally, you may want to try booting while holding down the command key, this will allow you to select your boot disk.
Also, that blinking actually indicates may indicated an error code. One blink is for invalid memory. Three blinks indicates failed memory. Check your User Guide for more info. If you've installed any upgrades lately, you may also consider removing them for the time being.

2009 Mac Pro Quad Will Not Boot

Hi.
I have a 2009 Quad 3.0Ghz Mac Pro that will not boot up.
I went to it this morning and the beach ball was spinning. I could not get it to stop and as a last resort, turned it off. It has been working fine, although
I have noticed a little slow (Could be me, though).
When I tried to reboot it, it tried to start, chime went off, but it stayed on the light grey screen and eventually, it had a folder with a question mark in it
that blinked.
I disconnected all peripherals, no change.
Tried to boot from the optical drive with Disk Warrior, no change.
Anybody have any ideas?
Thanks in advance for any help.
Brian

The Chime is generated in Software when the first part of the Power-On Self Test has passed. If an appropriate source of software can be found, booting is likely.
it had a folder with a question mark in it that blinked.
That says it could not find the last-specified source of software. the drive may be damaged, or it may have forgotten where it should be looking.
Tried to boot from the optical drive with Disk Warrior, no change.
Next try a 10.6 DVD. "A Mac that cannot boot from an appropriate Installer/Utilities DVD has a Hardware problem".
One of the simplest things it should be able to do is Startup Manager. Hold down the Alt/Option key at startup and it should draw a gray or blue screen and slowly draw an Icon for each potentially-bootbale device (including a bootable DVD, if inserted).

I have an early 2008 Mac Pro, which has re-booting problems. Also what does the spinning beach-ball indicate?

Hi, I have an early 2008 Mac Pro which has re-booting problems.
Processor speed is: 2.8
Memory: 2GB 800 MHz DDR2 FB-DIMM
2 x 28GHz Quad Core Intel Xeon
I am running OSX Yosemite Version 10.10
My Mac Pro keeps re-booting. Last year I had to replace my graphics card. My original card was the ATI Radeon HD 2600 XT 255MB, and that is what I have now. At this precise moment my Mac Pro is running perfectly, except that it is slow and the spinning beach-ball keeps appearing. I have managed to do some work with the disk utilities, verifying, cleaning and partitioning. Some errors were found and when it was cleaned this seemed to help my Mac Pro to function properly. Although I am able to use my Mac Pro now, from day to day I still experience re-boot problems. Also quite unexpectedly my mac dictionary has an error, it closed itself down and will not open at all, I had the message to say that a report will be sent to Apple.
I have tried starting my computer with an external hard drive fitted via a USB cable, I use for back-ups. This worked and I was able to wipe my hard drive clear and replace all info from the back up I had done only a few days ago.
This worked for a few days and then the same problem started again.
I am beginning to wonder if I need to buy a new hard drive.
If there is anyone who has some answers to help me solve my problem, I would be most grateful.
Robert

My mac pro keeps trying to boot up but will not.

My mac pro keeps trying to boot up but will not. How do I fix his?

What happens when it tries to boot up?

Need to erase hard drive and reinstall system on iMac but have misplaced original install disks. Tried to use a my copy of Snow lepord 10.6 from my Mac pro but will not boot. Can original install disks be replaced. Thanks

Need to erase hard drive and reinstall system on iMac but have misplaced original install disks. Tried to use a my copy of Snow lepord 10.6 from my Mac Pro but will not boot. Can original install disks be replaced. Thanks

Yes the original Install Discs can be replaced for a nominal fee. Call AppleCare, you will need a credit card and the serial number of the machine. You can use the AppleCare Contact Info for the phone number on your part of the planet.

Mac Pro (early 2008) wont boot pat the gray screen

First, my mac pro has three hard drives, bay 1 is time machine, bay 2 is empty, and bay 3 is A new Disk, running a newly installed 10.6.4. The computer was running great, then one morning I turned it on and the computer never got passed the gray screen after the chime and fan noise. I did a hard restart, holding down the power button, the computer booted normally to bay 3. This has happen twice. I have notice that if I restart from the OS it boots to bay 3 with no problems. It seem to only happen when the computer has been off for several hours.
Thanks for any help on this!

One thing at a time, and while I would hope you would use DW 4.2 on regular basis, plan for the worst and hope for the best, no reason to jump off the deep end and no, not processors or logicboard.
DW may not be able to boot your system from its CD, which I never use, just copy latest 4.2+ version to your boot volumes.
A printer or its cable, scanner, consumer USB device is much more likely, or drivers.
But, need to have a clean install of OS X (20GB volume) and a full boot image to play with first.
You can also use OS X DVD.
Safe boot mode - for when there isn't any other option and to do light maintenance.

Mac Pro 3,1 Stuck on Grey screen for 1 min during boot

I have a Late 2008 Mac Pro 3,1 and have started experiencing a very slow boot up. The computer gets stuck for over a minute on the initial gray screen after the first boot chime. Once the apple logo finally appears the boot goes normally. Once running it seems OK. The shut down seems normal with a grey screen for a few seconds with the "clock" logo.
Symptom:
After the chime I see a blank gray screen for in excess of 1 minute, it used to last only a couple of seconds.
Once the dark grey Apple logo appears the boot goes at normal speed
I have a number of different hard drives with older systems and booting from each of then gives the problem - so it does not seem to be system/disc related
Two partitions (Mavericks and ML) are on SSD's installed on a Sonnet PCIe Card and showed the same problem as the spinning hard discs.
I tried: (following a trawl of the bb's etc)
I repaired permissions and repaired all discs for all my boot partitions (10.5, 10.6, 10.7, 10.8 and 10.9) using the appropriate Disc Utility
Zapping the Pram - this was very strange as I had to keep the cmd alt P R held down for around a minute before the second chime occurred, the time of the grey screen stays stuck
Resetting the SMC
Booting in Verbose Safe Mode: Again I had to hold the Alt V down for a minute on the gray screen before the screen went black and the text appeared
I looked on the console log but could see nothing obvious, additionally from the verbose safe mode boot the text log seems to start from when the grey screen disappears. The time stamps show the boot finishing in well under the minute I wait.
Any suggestions you may have are very welcome.
Regards
Dave

Thanks The Hatter for that information. The blank gray screen is now lasting 3 mins before the Apple appears. When I restarted the system log is as below. As you can see there is just over a three minute gap between the shut down and the boot, indicating to me that it is not something in the system software after the boot but a problem at the very start. It does look like it could be something to do with the hardware as you suggest. I have verified all the discs with the disc utility and they report as OK and their SMART status is also OK. I have disconnected the external drives with no change so I will now have to do a thorough check and systematically remove the internal ones but that will have to wait for the weekend.
I have Mavericks on the Samsung 840 Pro and ML on a Crucial SSD (Crucial_CT240M500SSD1 Media) on a PCIe card. The Mavericks install I think was an upgrade, not a clean install done quite a while ago. I only noticed the problem this week when I re-booted in an ML to run some software not compatible with Mavericks. I have made a system back up as a precaution to an external disc just in case my main drive is dying!
There are some firmware updates for both the SSD discs that I have not applied these yet but I will leave them out of the mix until I have tried simplifying my configuration with a single disc.

Mac Pro 2008 won't boot from install disc - black screen

Hello,
I recently purchased a new hard drive to replace the original that came with my Mac Pro 2008. I was able to format the new drive using Disk Utility. I am now at the point where I need to install OS X onto the new drive, but the computer refuses to boot from the disc. The disc is recognized by the computer (I can access the disc and am able to use the BootCamp applications, etc.) but I just get a black screen when trying to boot directly from the disc. The computer boots fine otherwise.
I have tried the following:
I have tried using both the gray install disc that came with the computer and the Snow Leopard Install DVD disc.
I have tried booting using the "C" key and the "option" key but still receive a black screen following the chime (I've held these down for several minutes).
I have tried restarting from either install disc using the Bootcamp Assistant.
I have tried running the installation software to get it to restart from the disc.
I have tried a combination of the drives, i.e. trying to boot from the discs with just the new drive installed, just the original drive installed, and with both in bay1 and 2.
Everything results in the computer starting up, hearing the chime, and then nothing..just black screen. I have the original drive partitioned with BootCamp with OSX Snow Leopard and Windows 7 installed (I don't know that that matters).
I am at a loss as to what to try next. It doesn't seem like the superdrive because it is recognizing the disc, it just won't boot from it.
Any help is appreciated, thank you.

Clone should be a must and easy to do and learn (learn by doing! 2)
6800 would 'qualify' as 5x70 series flashed etc and same rule: 10.6.5
In the past there was 10.4.6, 10.5.6, but not 10.6.6 - even though strong need for such a DVD.
10.6.8 DVD would be excellent
Lion or ML - buy, download, make an installer flash card would be what I would do at this point.
Then keep both - dual boot as you learn and test and see what ML does and waht you had that required Rosetta to support PowerPC. See www.roaringapps.com about that.
With Carbon Coyp Cloner - was share, now commercial, great utility been around since 10.2.2 at least - this time 2003. 10 yrs.
You can clone the system folders, you can even selectively choose. You can skip copy of most of your home account and do that separately to another drive if you want.
Clone Windows with Paragon or WinClone and use Windows 7 or 8 DVD to do a system repair (automatic) or to edit the BCD file. It can and should - and all you do is boot Windows 7 DVD w/ only the one drive present and go at it. Piece of cake. But yes, Windows gets fussy if you change or remove or move. BCD to the rescue. A proper program for cloning like Paragon's "Clone OS" meant for going from disk drives to SSDs, knows that and how to do it.
Back to how to clone etc:
Clone
Disk utility has RESTORE which will also clone your system but not the Lion Recovery partition. Oddly Apple did not 'endorse' making bootable clone of the system which works too but most choose Carbon Copy Cloner - it works more consistently; it allows for smart update of the backup volume. Both can backup to a sparse disk image if desired.

The DVD is dependent on your hardware. And your hardware changed. The drivers for the 5780 and 6xxx are bundled in the OS and lacking. Minimum build thing.
Put the new drive anywhere you want. Does not matter. Can move it later. Can be drive bay 0-3 or a Firewire external or under the DVD drive.
When you clone pull the old drive and boot from the newly cloned.
After that keep a backup clone around all the time. Takes less than 10 minutes to do a smart update to copy just the changes to keep it current. So you have working copy of the system. I keep Clone "A" that I keep "as was" the system as of last month or whatever (like 10.7.4 before upgrade to 7.5).
Comes easier after doing it once and have all your ducks in a row.

Mac Pro 1,1 Ati X1900xt black screen on cold boots

I am having trouble with my video on cold boots. The video does not respond when directly booting into OS X but I can boot into bootcamp blindly and then I can restart into OS X. Kinda a back door entrance to OS X. I cannot tell if it is the Video Card (ATI x1900xt) or if it is in the Monitor as they both work under windows then back into OS X. As soon as I shut down, everything goes black sceen and I get no video input. I have tried three brand new different adapter from DVI-d to VGA on the computer all of them do the same thing. If there is ANYONE that might be able to shed some light on this, PLEASE HELP!!!!
Here is Everything I have tried...
1. nvram reset - done
2. SMC reset - done
3. pulled all ram and video card out - done.
4. pulled all extra drives out - done.
5. re installed OS X - Done.
6. checked DIAG-TEST - all LED's respond normally.
7. tried talking to the "genius techie" at MAC store to no avail - he was completely useless.
Thanks in advance.

This is now a three week plus old question.
There are tips on video cards like this:
http://www.xlr8yourmac.com/
To pull the card every 3-4 months to remove dust clogging the card's air chamber;
To boost system 3 of 4 fans to improve cooling and air flow.
Problems with that card and WoW have been around since early days on WoW forum.
And that there is a recall for some of the Mac Pro X1900s, also found on above web site.
AT this point in time, I'd skip ebay for ATI 5770 as long as you run 10.6.5 as you won't be able to boot anything lower than 10.6.4, so you need some good bootable backup strategy and more.
I have the 8800GT 1st gen (from Apple) $279 though there are/were tips on flashing too.
And ebay 'macvideo' or something has had 8800s if you want to go that route.

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.

Mac Pro 2006 won't boot after attempted cpu swap, Mac Pro 2006 won't boot after attempted cpu swap

I just picked up a used Mac Pro 1,1 (2006). It has 2x2.0 GHz dual-core processors and 5GB of RAM with the 7300GT card.
In this configuration, the machine was running perfectly. I, of course, wanted to upgrade....
I ordered a pair of 5160 3.0GHz processors cheaply and followed a video tutorial to install them. I used Arctic Cleaner and Arctic Silver 5 for the thermal paste.
Bottom line is: I installed the two new processors and when I fired it up, I could hear the fans, optical drive and hard drives all spinning (normal fan speed - NOT "jet mode", and the HD sounds like it's spinning - NOT like it's booting). NO boot chime and NO display. I popped the cover off and saw the CPU B FAIL light on. I swapped CPUs to test the processor, expecting to see the CPU A FAIL light come on. It did not. It just powered the fans/drives with no result (again, with no boot chime and no display).
To make a long and frustrating story short, I wound up putting one of the original 2.0GHz processors in slot A, leaving B empty (maybe I damaged the socket?) and IT STILL WILL NOT BOOT. I have tried all of my processors - the original 2.0GHz and the new 3.0GHz ones - with the same result. There are NO symtoms or indications - no error LEDs, no beeps - no indication why this machine will not boot.
I have reset the SMC, pulled (and replaced) the coin battery, and left it unplugged for over an hour. I have re-seated everything I can think of.
As of rigt now, I can hear the fans quietly humming with the optical drive making a quiet "click" sound as it seeks for a disk to read, and I can hear the faint chatter of the HD head. The power LED is nice and bright (no flashes or pulses), and there are no red LEDs on inside the case. The memory LEDs flash once during bootup and that's it (it's the RAM the machine came with). Pressing the DIAG LED button tells me the machine has power (green LED), has trickle (yellow LED) and the GPU light flashes green.
Of note, during the swap, I got a tiny bit of thermal paste (non conductive) on the contacts of my 2.0 CPUs - which I cleaned off with alcohol and let dry. The gold contacts all appear to be good on the original processors. I can't really see the tiny little pins in the CPU sockets (my eyes are not as young as they used to be!), but the "look" like they're all there.
I'm going to leave this unplugged overnight, but does anyone have any ideas?? If I managed to somehow destroy ALL of the CPUs, wouldn't I get a warning LED or beep or something? Ideas are welcome, as I cannot afford to replace this machine - it has to get me the rest of the way through college.
thanks
Richard

Hello Grant
>
Hardware sets the fans to maximum, and only properly-operating software resets them to "normal levels. If you have fans at normal levels, some software is running.
>
That's what I was thinking, but I'm not even getting the startup chime, and the HD sounds like it's powered on but not doing anything.
EDITED TO ASK: what software could be running at this point? Nothing has loaded from the HD, that much I know...
>Do you still have CPU A or CPU B failure lights?
No. I have just one original processor installed in the CPU A socket. No lights of any kind. (Even if I install an original processor in CPU B, I still occasionall will get a CPU B FAIL light, so I'm thinking I damaged the socket somehow...the light will not be consistent, but it's always the CPU B FAIL light - the light only turns on some of the time (and stays on once lit) - so that's why I pulled the B processor and am simply trying to boot with A alone)
>Do you have a flashing power on light, indicating failed or no memory?
Again, no. I can "make" the light flash by removing the memory riser, but when I re-install the riser, the light stops blinking (with power off during removal/install, of course!)
>Have you done the more severe SMC reset with the reset button OR:
unplug AC power.
Yes. I have used the SMC reset button 3 or 4 times. I unplugged the machine and left it (with coin battery installed) for an hour. The last thing I did last night was that I left it unplugged overnight (with coin battery removed). I have yet to attempt a power on this morning. I will do so and report back.
>
unplug AC power.
Press and hold power-on for a quarter minute to drain the power capacitors.
Re-plug AC power.
wait a quarter minute.
then power on.
>
Haven't done that one yet. (Didnt know about it!). Will try that second today, after attempting the initial boot up after leaving it unplugged all night. (fingers crossed) Of course, the capacitors are likely discharged now after being unplugged and battery-less all night, but you never know...
>Many things have to get synchronized after a CPU swap. It may take a half-dozen reset attempts before everything lines up again and goes.
Thanks for the hope. I will keep trying.
>
I recommmend you remove ALL distractions: all drives, all graphics cards, all PCI cards, all USB devices -- until you get the chime nothing else matters.
Already have done so. Last night I was down to 1 original CPU (CPU A), one memory riser with 1 set of original 1GB DIMMS, 1 bootable HD and nothing else (not even a keyboard/mouse - literally NOTHING else). Will keep trying in this configuration. All I really wanted last night was to hear the "bong" at power on!
Will do a bit more troubleshooting today and will report back.
Thank you!

Mac Pro 2010 Won't boot after adding Ram

Just got my Mac Pro 2.8 a few days ago. My 4x2 8Gig Crucial Ram upgrade arrived today along with my SIIG FireWire400 PCIe card. It seems as though the Mac Pro won't boot with both the Crucial Ram and the Samsung Ram that came stock with the Mac Pro. I kept 2 of the 1 gig Samsung chips and put in the 2 4Gig Chips from Crucial. They are all the DDR3 1066 240 pin chips. I've moved the 4Gig chips to slots 1 & 2 and I've tried them in slots 3 & 4. I've moved the 1Gig Samsung chips accordingly. The power light on the Mac Pro blinks continuously when they are both installed. I even tried removing the new SIIG FireWire 400 card but that doesn't change anything. It seems as though combining these two types of ram just doesn't jive. Any ideas? I'm dragging the tower from queens to SoHo tomorrow to let the Apple Genius gang have a look at it.

FYI, when I did install the Registered or "buffered" 8 Gigs of Crucial Ram by themselves the system did boot up normally and a memory notification popped up and said that my ram was in the "correct" or "suggested" configuration. I can't remember the exact phrasing but the OS definitely gave me a thumbs up. So now I am trolling the web trying to find out if the Registered memory is ok. I'm fine to just have 8gigs for now. But don't want to jeopardize the stability of my system. So, Is it ok to use Registered memory and if it is, am I using a lesser quality of ram in doing so?

Mac Pro Early 2008 not booting

Hey guys!
I walked into a problem with a Mac Pro early 2008 model.
I got this Mac Pro from somebody since it wasn't working anymore. I was told there could be a graphic card (Nvidia) issue which I think should at least be correct but I am also having trouble with loading EFI. The following things happen:
When I turn on the mac using a DVI to VGA adapter i have no screen at all. (I don't have any other options atm)
There is no HD inserted.
PRAM and SMC reset won't do anything, i'm not even sure it reads keyboard commands.
The fans all work even the one on the GPU.
Front LED just burns steady.
No lights on my USB (non Apple) Keyboard turn on.
The lights of the mouse just flashes on start up.
RAM LEDS light up on startup.
Motherboard reset button doesn't make anything change.
When I Press the button for the diag LED's, the Trickle Power and the Good Power led come on, the GPU LED stays off. The EFI LED is off aswel.
No RAM errors show up. Tried switching RAM and disconnecting RAM and GPU.
No startup chime what so ever.
I figured there could be something wrong with the EFI firmware (or logic board is just broken). I am trying to restore the firmware with a firmware restoration cd, but I can't get the cd tray to open. I pressed the on button and kept pressing it for a long time. All it does is makes my status LED flash a couple of times real fast, but then it goes back to normal state. No cd tray is opening and its not flashing 3 times fast, 3 time slow, 3 times fast as it probely should be doing.
You guys have any idea what to try next or how to restore the firmware?
Thanks in advance.

there's a boot code to run with the older machines
Pike wrote this code
Using this code will get you around the efi/boot issue and move on to OS 10.10.02
Installing Yosemite just prior to entering the efi/boot, then restart twice.
You'll need to research Pike's code, but your 2006 to 2008 machines are long ways from trash.
I'm upgrading my 2006 to 8 cores, Yosemite and 32 gig of ram.
Long live these early Mac Pros

Mac Pro will not find boot volume

Hello,
My Mac Pro will not find it's boot volume. Each time the computer is started, the blinking folder with the question mark is the result. A working install of 10.7 does exist on the machine's primary hard drive. If I were to press the option key on boot, I can select the primary hard drive (after entering the password) and everything boots as normal. I have run TechToolPro on the volume with no detected errors, even after a volume rebuild. A Recovery HD partition is not on the boot volume. Should that matter?
I really really do not want to reinstall Mac OS X. I have hundreds of gigabytes of data in question. Any reinstall/reconfig would take days to complete.
Thanks

So you are saying that setting the default in Startup Disk doesn't work?
And you have not got or been using Carbon Copy Cloner or another to provide working bootable backup?
You should have Lion Recovery on one of your drives, do a clean install.,
I assume TTPro media scan turns up no errors.
MOVE all your data OFF the boot drive. Keep the system OS and apps on its own drive.
Clone the system. Use TimeMachine and cloning for backup.
And how is the pram battery?
Any time you zap pram you lose the default and it will look for it like you see starting with SATA0 (bay 1)

Mac Pro 2009 won't boot after airport installation

Hey everyone, looking for some insight here.
I recently bought a Mac Pro 2009 running Mavericks (at time of receipt). It didn't come with an airport card so I purchased one to install myself. The Mac was running fine until this evening when I finally got around to installing the card, however since then it won't get past the grey boot screen with apple logo. I've tried disconnecting the airport card to see if that reverted it, but no change. I also can't boot into safe mode, so that's no good. The only thing I can do is bring up the giant padlock with the option key held, which I saw elsewhere was connected with a firmware password (my admin doesn't work).
Any advice here would be greatly appreciated. Thanks!

It wouldn't be much of a lock if you could circumvent it with advice from a forum.
Obviously a valid point, although possibly somewhat niaive where forums are concerned (no disrespect intended).
It was more an expression of frustration than anything else, to be honest, though. It's kind of absurd that this happened following a simple hardware upgrade. Most people I know aren't even aware they can set a firmware password, so basically what it means is don't upgrade a machine that's intented to be upgraded (I'm aware of the hyperbole here).
Looks like it will be a Mac store trip, though, yes. A pain in the arse since even my nearest authorised technician is miles away.
