Mac Pro 8 core w/2 24"LED screens

Just converted to:
Mac Pro 8 core 2x 2.2.6 GHz Quad-Core Intel Xeon
12 GB 1066 MHz DDR3.
No histogram in adjustments pane.
After straightening getting a white screen on crop that can be undone with a remove adjustment.
Re-installed Aperture 2, rebuilt library.
Update:
Aperture 2 seems to run well in single screen mode on the newest MacPro 8 core.
That is only single screen mode!
Double 24" LED Apple Cinema Displays cause the problem.
Using 2 NVIDIA GT 120 VIDEO cards as recommended.
No histogram registered in the adjustments inspector or the HUD.
Image going to black on second adjustment of any kind.
Auto levels whites out image.
Side note:
24" Led cinema monitors don't have a long enough display cable to adequately place the unit under a desk when using 2 monitors. No "mini display" extension cables available that I can find.

After several conversations with Apple. I have come to the conclusion that they are are working a a video card that will have dual mini display ports.
A Dell monitor is a solution if I didn't already have 2-24" Apple cinema displays and if it had the same color space as the Apple display. I have devised a work around for full browser mode with mirrored image:
I have come up with a temporary work around to for the short term.
I run Aperture in dual screen mode with a full screen browser on one monitor and and a mirrored image of the selected image on the other monitor.
This doesn't work with dual video cards.
The temporary solution:
1. Arrange the monitors in system preferences so the primary monitor is on the left.
2.Set the viewer mode to "Browser and Viewer"
3. Set the monitors in Aperture to show multiple on the main viewer and "desk top" on the secondary monitor.
4. Toggle the browser to the right hand side of the expanded image, with the inspector on the right hand side of that.
5. Stretch the view screen to cover both screens.
6. Resize the bowser and the inspector to cover the right hand screen.
This now simulates "Browser Only" with mirrored second screen. As long as the "expanded image" is on the primary screen Aperture adjustment inspector works and the images are stable with full histograms.

Can we use FCP conviniently while my mac pro is attached to a LED tv

can we use FCP conviniently while my mac pro is attached to a LED tv (46inch).
I am afraid if the icons will also blow up/get bigger and would become inconvinient to use.

most large TV sets are still 1080p (1920 by 1080).
The icons will appear to take up more space (in square inches) on the TV, but will be "grainy" compared to your monitor. The fundamental size of icons and items on screen (in pixels) will not change. When you return to using a monitor, things will be the same as before.

Where can i buy mac pro core 12 64GB (8x8GB) memory?

64GB (8x8GB)
for the mac pro core 12 memory

Yes. I've bought a lot of stuff from them over the years. And in fact when I got my mac pro I bought my ram from them too. They specifically cater to mac needs. They have a fairly liberal return policy. For example, I bought a eSATA card which turned out to not work the way I expected with my external enclosure (also bought from OWC). I returned it for another make of card with no problems. Reading these and other mac forums you will see a lot of recommendations for OWC.
And yes, I don't know why the url is macsales.com either. But it should be obvious from that choice of url they really do cater to mac ('er sales).

Mac Pro early 2008 boots to black screen

Four times out of five, on average, the Mac boots to a black screen -- a 30" Cinema Display.
I believe the computer is booting all the way up, because I have the front power button set to put the computer to sleep, and when I manually power down the machine using the power button, the Mac will go to sleep first.
Also, the Mac will go into Firewire disk mode when connected to my MacBook.
The "boot-to-black-screen" occurs from cold or warm boots.
I've tried both 10.5 and 10.6 OS -- no difference, results the same on both.
Here's what I've tried:
Reinstalling and updating OS both 10.5 and 10.6
Diskwarrior
PRAM zap
Pulling all USB and firewire peripherals off the computer (except the Apple Wired Keyboard that shipped with the PC) -- Mac promptly booted to black screen, so peripherals are not the issue.
Changing displays (in this case, a Samsung 17") -- same result
I have tried booting to the Apple Hardware Test on my commercial Leopard DVD and Snow Leopard DVD, but the machine will not boot to this (the Leopard disk will boot the AHT on other Macs). I no longer have the original CDs that shipped with the Mac.
I've suspected the video card, but according to other posts, apparently this is not the cause.
I'm now suspecting a motherboard firmware issue.
Before this, the Mac Pro was having a related issue pertaining to VMWare Fusion, wherein the Mac would occasionally not wake from sleep, logging a VMWare Fusion kernel crash.
For the moment, I'm not shutting down the Mac Pro, just turning off the Cinema Display. I've left this computer running for up to two months without a reboot, so I'm confident that it will stay up and remain stable.

I'll watch to see if you get an answer. I have a late 2008 Mac Book Pro 15 with the same problem. It boots xp good every time. But I often need to use external monitor to gain control of the OSX boot. It gives tone, shows gray, shows apple and gear the short blue and then strait to black and front LED seems to indicate sleep. Very frustrating. Happens on both use best graphics and conserve battery display settings. Tried the reset pram, safe boot, save boot verbose. All no good.

Mac pro (2008) won't start - led flashes

it's been a while since i've had a mac issue.
today my mac pro decided not to boot up. the led light by the power button simply flashes and i have no image on my monitor and it doesn't chime at attempted start up. i've scoured the forums and it appears it may be an issue with the RAM and/or video card.
in this thread - https://discussions.apple.com/message/12852794#12852794 - a poster said:
"If the status light still flashes, determine the number of flashes to identify the problem:
• One short flash followed by a longer off period: No valid memory.
• Three short flashes followed by a longer off period: Failed memory."
does anyone know what continuous led flashing might mean?

The conventional way to proceed when you have no chime is to remove all items that may be dragging down the power supply if they were malfunctioning.
Remove:
Hard drives
optical drives
PCI slot cards including the graphics card
all the memory except the minimum -- be sure to remove and re-insert each module that remains, to clear corrosion. If your Mac has separate riser cards, remove and re-insert them as well.
Try to start up again, looking for the chime.
A) If you get the chime, add the graphics card so you can see what is happening. The minimum needed to do something is to start up while holding down the Option key, to run the [all-in-ROM] Startup Manager. It will show a blue screen and an image for each bootable drive (there won't be any yet).
Then add in the optical drive and attempt to boot from an Installer/Utilities DVD appropriate for your Mac, or try the Apple Hardware Test DVD (and hold down the D key as you start up, as it says on the face of the DVD).
B) If you don't get the chime, it's off to the repair shop.

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 display flickers with a white screen and then display closes

Hi,
The display on my Mac Pro started showing a white screen and flickering.
So I tried formating and re-installing 10.4.10. I am able to complete the installation of first DVD without flickering. But when after the restart after installation using first DVD then the flickering resumes.
Any idea what is the issue and how we can solve this issue.
The AHT test shows this code 4 SNS/1/40000001:ICAC. According to
http://support.apple.com/kb/TS2081?viewlocale=en_US the code should have a trailing number - but my report does not have any number. Is this error code fine? If no, can some one tell me what is the error in the system?
Thanks,
Ed

Same symptoms here. We tried AHT on a good Mac Pro with the video card from the bad mac, and got the 4 SNS/1/40000001:ICAC error. Looks like a bad video card.
Here's another thread discussing the problem: http://discussions.info.apple.com/thread.jspa?threadID=2071334

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 won't boot past grey screen because of bonehead move?

Hey everyone,
So today I wanted to free up Macintosh hd space to have room to install new software I purchased. During trashing certain files, I noticed there seemed to be a duplicate folder of library so I decided to trash that duplicate library folder. When I went to go empty the trash consisting of library and other various files, the trash button would not work. It would press in but nothing would happen. So I decided to reboot the Mac pro and when it turned on, I got the gray screen with the apple logo, folder with question mark flashing. Did I delete something I wasn't supposed to? What should be my next step in solving this issue?
Thanks

Before you do some heavy maintenance, clone your drive, maybe just get a larger drive and clone, then use the old original as backup.
Restore everything from the trash of course for starters. But a new drive or two would also be a good idea. Then buy Disk Warrior and SuperDuper to handle maintenance and backups.
If you had TimeMachine running you might also recover files.
But you need to boot from another drive or DVD. Maybe install OS X to another drive (shrink volume so you have 30GB).
Installing software in today's age of disk storage shouldn't require trashing files, unless you are working on old Raptor or small SSD.
And instead of trash, move files to another drive, and always keep media files and libraries (not system libraries) off your system drive and onto a data drive.
When in doubt, unsure what something is... don't!

Mac pro still hangs on the blue screen on start up.

Hi.
my mac pro still hangs for ages on the blue screen before the login page where i input my password appears.
i've tried starting up in command-V and that didn't work.
i thought snow leopard was meant to improve, it has just slowed my start up down greatly!
could someone please advise on how to fix this?
thanks
Dan.

Hi boom,
Have you tried downloading and re-applying the latest Combo update?
If not, go to the apple download page, find the Combo update (couple of hundred MB) and install it.
This has fixed various issues in the past for numerous users... it might do the trick for you.
After it's installed and rebooted, repair permissions and reboot again.
Also check to see (using software update) if there are no firmware updates available for you.
And, make sure the OS drive's root is clean, just the basic Applications, Library, System and Users folders, no other mess. If there are 'Previous System' folders from earlier Archive & Install situations you might want to remove those.
Finally, if you upgraded from a PowerPC to Intel using the Migration Assistant the symptoms you are describing are very common, the migration assistant well... it ***** :/

Mac Pro 1,1 freezes on boot screen, hard drives are accessible via network

My Mac Pro 1,1 today failed to display anything on the monitors when I woke it from sleep mode, even though it sounded like it was running.
Upon restarting the computer, it chimed as usual, made fan and hard drive spinning sounds, and went to the boot screen, where the little grey, dashed circle went around for a little while, but then it froze.
The hard drives kept making noises, so I waited, but nothing happened.
So I tried the following things;
• Restarted
• Zapped PRAM
• Unplugged USB devices
• Disconnected power cable for over 15 seconds
• Pushed PMU reset button
• Tried to boot from Snow Leopard DVD
• Pushed on graphics cards and RAM risers to make sure they were seated
• Looked inside computer to see if anything looked out of place (nothing really)
• Smacked side
Nothing helped.
Even when I tried to boot from the Snow Leopard DVD, it did the exact same thing; showed the boot screen, spun a little, froze.
I got on my MacBook Pro and was able to access the hard drives over my WiFi network, so I know the computer is running on some level.
This computer has been running slowly for awhile, which I attributed to running out of disk space and having lots of browser windows open, and I think it had a couple of kernel panics recently. Also the monitors went haywire a couple of weeks ago after I shut the computer down while it was running on UPS power, but I was able to fix one by doing a factory reset. I don't know if any of that is related to this problem.
Also, I currently have both the factory graphics card and a more powerful graphics card for GPGPU simultaneously installed (forget the model number, but it's the one that dies and you have to bake it to make it work again). It's not glitching up at all though; just spinning a little on the boot screen and freezing. I tried unplugging one of the monitors from the graphics card I had it connected to and plugging it into the other one, but it didn't make any difference.
I also recently ran disk first aid on all my hard drives and it said they were fine.
Any ideas???
Anyone have any ideas?

The Boot screens use a very simple mode of display, typically shared by Safe Mode, Alt/Option boot, Recovery mode and stand-alone Installer. Once you get to the login screen, the Driver loads and the most complex interrupt-driven parts of your graphics card must be working to display a picture.
The cards in older Mac Pros do not have a history of long, trouble-free life. There are many, many threads here that are solved by replacing the card, especially with a more modern one.

Mac pro stuck at apple logo loading screen after software updates

I have an older MBP from 2008 - was prompted to do updates tonight and let it update and restart. It gets stuck at the gray apple loading screen and does nothing else. Have tried resetting PRAM and booting in safe mode. Safe mode works fine but nada on normal. Also tried giving it plenty of time to boot but it continues to load (with the little circle animation under the logo) and nothing ever happens.
Any ideas or suggestions? grateful for any help!! :(

Try starting your computer with the original DVD that came with your Mac Pro then run disk utility on your hard drive to repair it. If you are running Mac OS X 10.7 then start your computer in Mac recovery mode (command + R) then run disk utility on your hard drive.

Mac Pro and two new Apple LED Cinema Display 27" brightness control

Hi all,
Have been using my new Mac Pro (HD5770) with one 27" display for a while and am loving it and to make my work easier I got one more 27" display but how do I change the brightness on the second display? Only the first one can be changed and it's a big difference in the colors on the displays.
With Best Regards / Christian

Make sure you have the display update installed. Look for the ambient light sensor control in Displays system preference to see if it's installed.
<http://support.apple.com/kb/DL1107>
<http://support.apple.com/kb/HT4293>
Turn off mirroring.
Do you have brightness slider for both displays?
Try unplugging the USB cable for one display so you can adjust the brightness on the other.

Mac pro wont boot no chime blank screen fan running 100%

When switching on the mac no chime happens, fans come on as normal then build up to 100% speed and all that happens is the light solid on the front and black screen, did the diagnostic on the logic board all that lights up is the orange trickle LED, i have done reaserch on this and aparently the riser cards have leds that light up when turning on the machine, i have also read that it could be a logic board needs replacing im really hope its not that and something else because they cost a fortune to replace. if anyone knows what is happening would muchly appreciate help
thank you

fair enough thought it would of been a logic board prolem i will try taking out the card and see what happens. if like you said it beeps do i need to replace the power supply ??
If it beeps with the video card removed that would mean it's the video card that is the problem.
I gave the computer a general clean last night but nothing major as in pulling out the cpu and giving it a clean, could that also be a problem ?
It's always good to limit the dust just to minimize overheating. But I don't think that the problem here. Just good maintenance.
also another question what are the symptoms of a logic board failure?
Machine does't work? I can't really be definitive. What happens if there is a logic board failure in your TV? I think you get the line of thought here.
thank you again you are being most helpful
You're welcome and good luck.
