Mac Pro, Lion: front light flashing, fans blowing, and doesn't startup...

This has never happened before: my Mac Pro's (Lion) front light flashing, fans blowing, and doesn't startup...
Any workaround? Help, please...

If there is no response to keyboard or powerbutton presses; hold power button until it shuts off. Unplug and wait 5 minutes and then plug back in and try to start again.
Post back with results.

My Mac Pro won't start up, fans blowing hard.

Hi,
I bought a secondhand Mac Pro 1,1 - dual core 2,66 Ghz a few months ago.
The company I bought it from put an ATI Radeon 5770 HD and a 150 GB SSD in it.
It ran completely fine untill yesterday afternoon.
I needed some extra storage space for my files, so I opened up my broken iMac G4, unattached the hard drive.
This is what happened:
I shut down my Mac Pro,
with all the cables attached I moved the Mac over,
I opened it up, put in the extra hard drive in bay 3 (power chord still attached), closed it and tried to power it on.
The graphics card's fan began to blow immediately.
I heard no startup chime. Ten seconds later the main fan began to blow.
There was no video output, the screen stayed on stand-by.
The Diagnostic leds show only 'trickled', no other leds.
I searched alot on the internet for a solution, and tried all the resets and solutions I could find.
A brief list of what I've tried:
-pram reset
-smc reset (manually and automatically)
-boot without graphics card
-boot without RAM
-boot without cd-drives
-boot without harddisks
-I pulled all elements out (graphics card, ram, power supply, HD's, cd-drives) to check for broken or loose connectors.
Nothing worked so far.
What I did find, are some damaged power cords from my cd-drives:
http://www.flickr.com/photos/75710783@N02/8389915636/sizes/o/in/photostream/
Could this be the thing that started this problem?
And if not, what could possibly be wrong?

The existing breaks in the power leads for the Optical drives should not cause this problem when the optical drives are disconnected, provided they are not shorted to something else.
But if, at some time, they shorted out, it could have confused or damaged the power supply.
First, reset everything:
Remove AC power.
Press and hold the power-on button for a quarter minute (this drains the capacitors).
Wait a quarter minute more.
Restore the AC power cord.
Wait a quarter minute more.
Attempt to start up again.
To check for damage, measure the DC Voltages at a Molex connector (such as the one that is not damaged). You should find a bit above 5 Volts on one of the outside leads (often red wire) and a bit above 12 Volts on the other outer lead (often yellow wire). This should be relative to either/both inner wires (often black wire) or any other black wire, or the frame.
( If you do not already have one, a perfectly serviceable digital multi-meter for this purpose can now be had for as little as US$10, and does not require a degree in rocket science to measure DC Voltages. More money buys a higher-quality instrument with additional precision that is simply not necessary, but not an impediment)

Mac pro 2006 dont boot but fan's running like ****.

guys, my mac pro 2006 starts with the fan loud , seems running at total velocity. The video card doesn't show nothing. The usbs dont work. when i extract the video card , the problem is the same. I take the memory too, and the hd . The problem keeps going on.
The fan start's from zero to a million rpms.
The check leds on the motherboard are ok, no one of them are lighting. If i take every part of the machine and i put them outside, the same thing happen.
can you helpme?

Make sure your Ram is paired correctly when you install it --
And the long boot time is due to the previous reply. If you don't set a 'boot drive' the mac pro will look everywhere before selecting the OSX installation.
I've got the dual 300GB Velociprators in raid 0 with 80GB Intel ssd boot drive in my mac pro (same as yours). You can also boost your clock speed by a software trick .. I can get mine over 2.9 MHz before errors start popping up in console.
(problem is it screws up video playback and time)

Please help me ,i forgot the synchronising password for my mac pro lion backup disk

please help me ,i forgot the synchronising password for my mac pro lion backup disk

If the backup volume is encrypted, and you forgot the password, then you'll have to erase the volume and start a new backup. There's no way to recover the password.

Mac Pro bootup issues: started with graphical artifacts, and now nothing.

My computer specs:
- Purchased August 2008
- 2x 2.8GHz Quad-Core Xeon
- 2 Apple 1GB RAM sticks
- 2 Kingston 4GB RAM sticks
- NVIDIA GeForce 8800GT 512MB
-== The Saga of Trouble, Episode 1: Into the Very Heart of Trouble ==-
Started World of WarCraft. Trying to get rare Green Proto-Drake mount. Suddenly, approx. 3 minutes after starting the game, the display goes haywire: artifacts, flickering, you name it.
Tried:
- Power-cycling display: image returned, still messed up.
- Command-Q: nothing, no response.
- Yelling at computer: nothing, no response.
- Holding in power button to shut down: system shut down.
- Rebooting: no REFit bootup (I have REFit installed), and the gray Apple logo has graphical artifacts. Eventually I'm brought to a screen that looks like something out of an NES where the cartridge hasn't been cleaned.
- Rebooting with a different monitor: same result.
-== The Saga of Trouble, Chapter 2: Love is the Key, But Only When Contextually Relevant ==-
Cursing several times, and promising the Mac Pro swift physical retribution should it refuse to work, as, in my hubris, I haven't made a Time Machine backup in a while, I unhooked all cables from the tower, set it on an appropriate work surface, and opened it.
Tried:
- Dusting the interior with compressed air: dusted without incident.
- Checking to ensure graphics card was well-seated: it was.
- Checking to ensure RAM sticks were well-seated: they were.
- Complimenting self on proper usage of past tense: false sense of satisfaction given my Mac Pro's trouble.
-== The Saga of Trouble, Third Strike: Startup on Low Forward Reduced by Two Frames ==-
Reconnected everything and attempted to boot. A fan that normally whirs on startup (I assume from the graphics card, but I didn't visually confirm in the past) is not whirring. The characteristic "Apple noise" is heard, but nothing on screen.
Tried:
- The other DVI port on the graphics card: no dice.
- Another monitor: nothing.
- Another monitor on the other DVI port on the graphics card: no luck.
-== The Saga of Trouble, Future Shock: Escaping the Saga of Trouble ==-
With two upcoming trips, all part of chasing my dreams to become an awesomely famous screenwriter and game designer, instead of just an aspiring wannabe, I cannot afford to do what I think will solve the problem, and that's purchasing a new graphics card.
Given my foolishness in not making regular Time Machine backups, reinstalling the OS is going to be a last resort. As in I'm not trying that until I've exhausted all other options (which, as taught in college and in the four years of my life I wasted as an IT guy for an ISP, is not what you should try first anyway). I'll exorcise the HDD and plug it into something else before I reinstall the OS.
Given the above two points: what's my next step? Is there something I can try before either purchasing a new graphics card or reinstalling the OS?
Many thanks in advance for any advice.

Apple firmware (or flashed card).
The ATI line of Apple cards use universal EFI (EBC) so even the new 5770/5870s work as well.
Check the test results coming out on
http://www.barefeats.com comparing cards.
I realize the hard restart may be 'necessary' but booting from DVD or running the single user mode command FSCK -fy can minimize directory repair problem if you don't have OS X on another drive.
Installing OS X is fast and easy if you can shrink 30GB off another drive that you would then be able to boot from and has just mini OS and utilities.
Cache files often are the first to become corrupt as well, or prefs, anything that was in memory and that are changed frequently and after a startup. Cache files are automatically rebuilt and no fear if you can delete those.
AppleJack and Snow Leopard Cache Cleaner can 'enhance' what diskutil fsck you can do and add some more commands.
8800GTs are harder to find, still on ebay at times.

Which Mac Pro? More cores=slower speeds? And most of us know the speed matters or FPU for music and I don't understand the faster is for the least amount of procs. And while I get the whole rendering thing and why it makes sense.

Which Mac Pro? More cores=slower speeds? And most of us know the speed matters or FPU for music and I don't understand the faster is for the least amount of procs. And while I get the whole rendering thing and why it makes sense.
The above is what the bar says. It's been a while and wondered, maybe Apple changed the format for forums. Then got this nice big blank canvas to air my concerns. Went to school for Computer Science, BSEE, even worked at Analog Devices in Newton Massachusetts, where they make something for apple.
The bottom line is fast CPU = more FPU = more headroom and still can't figure out why the more cores= the slower it gets unless it's to get us in to a 6 core then come out with faster cores down the road or a newer Mac that uses the GPU. Also. Few. I'm the guy who said a few years ago Mac has an FCP that looks like iMovie on Steroids. Having said that I called the campus one day to ask them something and while I used to work for Apple, I think she thought I still did as she asked me, "HOW ARE THE 32 CORES/1DYE COMING ALONG? Not wanting to embarrass her I said fine, fine and then hung up. Makes the most sense as I never quite got the 2,6,12 cores when for years everything from memory to CPU's have been, in sets of 2 to the 2nd power. 2,4,8,16,32,64,120,256,512, 1024, 2048,4196,8192, 72,768. Wow. W-O-W and will be using whatever I get with Apollo Quad.
Peace to all and hope someone can point us in THE RIGHT DIRECTION. THANK YOU

Thanks for your reply via email/msg. He wrote:
If you are interested in the actual design data for the Xeon processor, go to the Intel site and the actual CPU part numbers are:
Xeon 4 core - E5.1620v2
Xeon 6 core - E5.1650v2
Xeon 8 core - E5.1680v2
Xeon 12 core - E5.2697v2
I read that the CPU is easy to swap out but am sure something goes wrong at a certain point - even if solderedon they make material to absorb the solder, making your work area VERY clean.
My Question now is this, get an 8 core, then replace with 2 3.7 QUAD CHIPS, what would happen?
I also noticed that the 8 core Mac Pro is 3.0 when in fact they do have a 3.4 8 core chip, so 2 =16? Or if correct, wouldn't you be able to replace a QUAD CHIP WITH THAT? I;M SURE THEY ARE UO TO SOMETHING AS 1) WE HAVE SEEN NO AUDIO FPU OR PERHAPS I SHOULD CHECK OUT PC MAKERS WINDOWS machines for Sisoft Sandra "B-E-N-C-H-M-A-R-K-S" -
SOMETHINGS UP AND AM SURE WE'LL ALL BE PLEASED, AS the mac pro was announced Last year, barely made the December mark, then pushed to January, then February and now April.
Would rather wait and have it done correct than released to early only to have it benchmarked in audio and found to be slower in a few areas- - - the logical part of my brain is wondering what else I would have to swap out as I am sure it would run, and fine for a while, then, poof....
PEACE===AM SURE APPLE WILL BLOW US AWAY - they have to figure out how to increase the power for 150 watts or make the GPU work which in regard to FPU, I thought was NVIDIA?

Hello. My mac pro early 2008 restarts after sleep mode and it works slower. I tested it with apple hardwear test and it seems to be ok. Thank you.

Try this:
clone your system and repair it with Disk Warrior instead
Or try a clean test system install on another drive
A must: SmcFanControl 2.2 - a mere 400 rpm extra to keep air cooling up
Try to run w/o externals. MyBook included.
Is that a 7200.11 1TB? they had a lot of issues.
Run AHT off your OEM DVD.
2008 had to have EFI and SMC updates to deal with freezes on wake from sleep, and like all models, high inrush current. Hopefully you have a UPS and is 1500VA unit.
When you do hard restart from power button, you almost certainly add more directory errors and to files requiring immediate attention to repair and rebuild the directory; and to scan and repair and delete cache and temp files and folders. A must. Invest in bootable backups SuperDuper along with Disk Warrior (or TechTool Pro 6, maybe Drive Genius 3 but I'd rate that #3).
TimeMachine has its own bad habits, especially with Green drives and some externals.
Try to rule out everything and then add back one at a time.
And it may just be time to replace the 8800, very common, a couple threads this week, and it is 3 yrs old. Might want ATI 5870 or 5770.

I have a new Mac Pro. I want to use my old Mac Pro as a storage drive for photos and old documents, linked to my new Mac Pro. How do I set up the old computer?

I have a new Mac Pro. I want to use my old Mac Pro as a storage drive for photos and old documents, linked to my new Mac Pro. How do I set up the old computer? Both computers have OS X10.9.3. Currently they are connected by a Firewire 800 cable.

You certainly could keep the old Mac Pro in Firewire mode (hold down the T key on its keyboard as you boot) to show its drives on the new MP. This is basically as fast as putting the drives into a Firewire enclosure.
Or you could boot it normally and share its files over the network using the Sharing panel of System Preferences. If you turn on both File and Screen Sharing, you don't even need to have a monitor attached - you can do all administration using screen sharing. However, this method requires that you open all files over the network, which will be slower than the direct-connect method above, and may also not work with all applications.

I had a second hard drive added to my Mac Pro. How do I format it and not effect my orginal hard drive?

I had a second hard drive added to my Mac Pro. How do I format it and not effect my orginal hard drive?

Just format it with Disk Utility as mentioned above. Select the new disk on the list at the left. Click the erase tab. Specify Mac OS Extended (Journaled) if not already specified and give the disk a name of your choice. Then click the erase button.
That's the simplest way to format a disk with a single partition (volum). If you want to create multiple volume (partitions) then click the Partition tab instead of Erase. You can then use then specify a number of volumes and size each volume by specifying its size or just dragging the slider in the bootm right of each partition. Give each a name as before and again Mac OS Extended (Journaled). Click Apply button to create the partitions.
Since you appear to be new at this just "play" with the erase and partition settings so you can become comfortable with them. So long as you have the new disk selected on the left you can't really hurt anything since it's a new disk and no data to loose. You can always go back and erase it back to a single partition.

I have updated my mac pro to os mavericks but now my mouse doesn't function like before

? have updated my mac pro to os mavericks but now my mouse doesn't function like before. Any suggestions pls?

My magic track pad works fine, the magic mouse cursor stayed in the central part of the screen and would only move up and down on a slight diagonal. I went into system preferences/mouse/more gestures and disabled all swipes. Problem solved.

My Mac Pro Lion 10.7.4 is getting hot, and the fan is making some noise.

2008 Mac Pro Monitor loses picture, computer becomes unresponsive and the fans run fast.

My early 2008 Mac Pro is dropping the signal to the monitor and the fan on the back begins to run at max speed. I have to do a force shut down and start again. It will then run ok for several hours. This typically happens when it wakes up, I log in and begin doing a task. However, it has been known to do this at a random time. This has progressed to a once a day event mostly in the morning after it has been sleeping for several hours.
I pulled the cover when it did it last and pressed the diagnostic button. LED's for the GPU and PWRG did not light.
I am wondering if it is the power supply beginning to fail or if it is the logic board or, is it something else.
Can anyone help with this?
Thank you
Processor 2 x 2.8 GHz Quad-Core Intel Xeon
Memory 6 GB 800 MHz DDR2 FB-DIMM
Graphics ATI Radeon HD 2600 XT 256 MB
Software OS X 10.9.5 (13F34)

When using the Hardware Monitor software (from http://www.bresink.com/osx/216202/Docs-en/faq.html ) -- i emphasized the stuff in red
The sensor X shows the reading Y. Is this normal?
If you want to find out whether a sensor value is within normal limits, please select the menu item Window > Show Overview (or press ⌘+1) and look for the limits in the third and fourth columns of the sensor table. They contain the known official limits Apple has specified for readings acquired at the given sensor locations. If no limit is given in the table, this either means that it does not make sense to specify a limit for this particular sensor (e.g. the battery capacity should not have limits), or Apple hasn't published any specifications for this sensor.
Note that all up-to-date Macintosh models automatically shut down or enter sleep mode if one of the readings exceeds a critical limit. For this reason it is impossible that your computer can be damaged in an overtemperature condition.
For old computers without temperature managment, no limits have been specified by Apple. In this case use the following limits as orientation:
Most older G3 or G4 processors are designed for a maximum operating temperature of 105 degrees Celsius (221 degrees Fahrenheit), measured at the chip die of the CPU.
G4 processors of type 7455 or later (typically used in Macintosh systems with 867 MHz and above) are designed for a maximum operating temperature of 65 degrees Celsius (149 degrees Fahrenheit), also measured at the chip die of the CPU.
Most desktop hard drives are specified for a maximum operating temperature of 55 degrees Celsius (131 degrees Fahrenheit). For exact information, use the Drive Overview window (⌘+8) to get the manufacturer and model code of your hard drive, and then direct your web browser to the manufacturer's web site to download the official data sheet for this drive. The temperature limits are always specified.
==================================
And don't forget you can look at the fan speeds (there are several in the Mac Pro) - that sometimes will give you a hint something abnormal is going on if the fans start running a lot.

Mac Pro Lion 10.7.5 will not receive bluetooth file from Macbook Leopard 10.5.8

Since late 2008, I have been running a 2.2GHz / 3,1 / 4GB MacBook, now at 10.5.8. A few days ago I bought a 2.66 GHz / 1,1 / 6GB Mac Pro, now at 10.7.5. I can not seem to get the Lion Mac Pro to successfully receive a 3.3mb file sent, via BLUETOOTH, from the Leopard Macbook. Sending the file, from the Leopard MacBook, usually, fails and gives the message, "There was an error connecting to the device". A few times I did get an incoming file alert on the Mac Pro and the file seemed to begin coming from the MacBook; however, the estimated time varied wildly and the file transfer eventually failed and displayed the aforementioned message. I have an android 2.3.6 phone and I was able to successfully send the same 3.3mb file to the Mac Pro in a matter of a minute, or so. I may downgrade the Mac Pro to 10.5.8, because I have important software/hardware that may not be supported on Lion, but, right now, I am trying to determine compatibility with my important Leopard software/hardware. For the time being, I want to send files to the Mac Pro via BLUETOOTH, as opposed to any other transfer method.

I don't know the answer to your problem, but until you resolve it do not upgrade OS X.
I would suggest you try a reinstall:
Reinstall Lion, Mountain Lion, or Mavericks without erasing drive
Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Repair
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported then click on the Repair Permissions button. When the process is completed, then quit DU and return to the main menu.
Reinstall Lion, Mountain Lion, or Mavericks
OS X Mavericks- Reinstall OS X
OS X Mountain Lion- Reinstall OS X
OS X Lion- Reinstall Mac OS X
Note: You will need an active Internet connection. I suggest using Ethernet
if possible because it is three times faster than wireless.

Mac Pro will not boot, revs fans at full speed

Hi,
I had my Mac Pro (2006 3.0 quad core) asleep, it woke itself up and didn't display video, instead revved the fans at full speed and did nothing, so I shut it down using the power button. When I turned it on, it did/does the same thing, no chime, no video to the displays, and I cant boot in safe mode or any other way, it wont even eject the DVD drive if I hold the mouse down.
has anyone encountered this before?
Any ideas?

Give the SMC button a kick, hold it in for 5-10 seconds. Hard to see, but hidden by drive #4.
Or try zapping PRAM/NVRAM first and see if that helps.

CS4 Premiere locking up royally on little mts files on Mac Pro Lion 10.7, is CS5.5 any better

Sorry for long title, got the boxes mixed up.
Having trouble working with HDV mts files in CS4 Premiere on a new 12 core MAC Pro with Lion 10.7 OS
Have used Adode CS3 and now CS6 at my office regularly. CS6 can work with about any file type.
Found this ClipWrap program on online and have re-wrapped these mts files into .mov files. They do open and must be each rendered out and do so slowly. Scrubbing the video doesn't do well - locks it up.
Very certain I have plenty of Computer power, is CS4 a dog? It will open CS6 projects that I bring home from work and do basic cutting on with M2T files and MPEG2 HD video.
I also do not see near as many Transition and Effects options for Audio or Video in CS4 as I had back with the old CS3 when I use it - very puzzling.
Would CS5.5 give me more optimal performance with this MAC? Do I need a third party card? We now run full HD on CS6 at work without using the Blackmagic card I have. Should uninstall and re-install the software? I am a video editor, just doesn't seem to perform like it should.
I am considering looking into the Final Cut X after this. Thoughts on this subject welcome.
Thank you.

Anything??
