Problem with mac pro 2x2.93 GHZ Dual Core and Mini Display Port

Finally I see the button to create new post!
I would like to explain a problem I have with my mac pro 2x2.93 GHZ Dual Core Intel Xeon processors and the ATI Radeon HD 4870.
I have two 30 "Apple. After buying the new Mac Pro is one of the two monitors, only with the monitor all black, small horizontal lines.
This happens only to the monitor connected to the mini display port... So if you reverse it monitors the problem always moves on the board connected to the Mini Display Port.
Apple has already changed my video card and the adapter but the problem is still there.
Someone can tell me if it is the ATI Radeon HD 4870 that has problems to have two monitors 30 "? Or it could be that the mini display port that is hard to read the two monitors and when the background is black (RGB-255-255-255) makes these lines?
Through the Apple store I then bought a new card (EVGA GeForce GTX 285 "). Unfortunately, after three weeks of waiting is not yet arrived. Proof that I want to do before returning to telephone assistance is whether on a card that has two dual-link DVI ports normal all goes well.
Sorry for the repetition of messages, but my English is very bad. This is the first time I connect to this site support

In any case, this system does not support two 30".
I honestly don't think the 4870 with that adapter can support two 30". Just using the adapter itself would not give me the normal resolutions on my 30, where as the DVI port did. Luckily for me the adapter worked fine on my 20".
Truly I don't know why Apple would sell a card and not say just what displays it can power.
So I worked around my problem fine but I chose to get the 285 also. My question to you though is, did Apple make you pay for it? Was it part of a deal with them because the Radeon didn't work? You might want to talk to them about that. That is one expensive card.

PROBLEM WITH MACBOOK PRO 2.4 Dual Core and MOTU Ultralite

Hello,
I Recently bought a macbook pro to have for my Live appearance.
I also had a motu Ultralite which worked super well with my Pc and with the macbook the first days
One day i had to play live in a club so i connect my soundcard but the macbook wont recognize it coz i cant see the popup window that i get everytime i connect my motu on it...i rebooted the soundcard then the laptop nothing...i started sweating coz my live performance would start in 20 minutes noting came out of it so i cancelled the gig for the moment and played a Dj set instead.
When i got home i connected the card again and was working perfectly till yesterday..So i thought there was something wrong with the Power in the Venue or something like that.
Yesterday i connected the soundcard and again does the same any other firewire device was working properly.
I searched online and saw there is alot of people having the same issue but no solution.can someone tell WHY sometimes it works and sometimes doesnt??its very stupid to have 2 machines with a cost of 2500 euro almost and they dont work well together
Op system: Leopard 10.5.7
Motu ultralite Mk2 firmware: 1.15
motu ultralite driver 1.4.21
Thank you in advance

Popping in to say that I have now a fully functional Ultralite (mk3) under OS X 10.5.8 on my Macbook.
I have found that people who have upgraded the firmware to 1.15 were having problems (according to the MOTU site this upgrade isn't actually meant for the mk3 anyways) with Leopard (maybe Snow Leopard too?) and needed the 1.00 version of the firmware.
Using the drivers supplied on the MOTU CD, the device would not appear when connected to the Macbook. However, removing these from the system prior to downloading the latest MOTU Universal driver from their website seems to have solved it.
Now after installing the universal drivers from the website the device works without any problems (driver 1.4.23 of MOTU Audio Setup). Hope this helps someone

Upgrading to Snow Leopard
You can purchase Snow Leopard through the Apple Store: Mac OS X 10.6 Snow Leopard - Apple Store (U.S.). The price is $19.99 plus tax. You will be sent physical media by mail after placing your order.
After you install Snow Leopard you will have to download and install the Mac OS X 10.6.8 Update Combo v1.1 to update Snow Leopard to 10.6.8 and give you access to the App Store. Access to the App Store enables you to download Mavericks if your computer meets the requirements.
     Snow Leopard General Requirements
       1. Mac computer with an Intel processor
       2. 1GB of memory
       3. 5GB of available disk space
       4. DVD drive for installation
       5. Some features require a compatible Internet service provider;
           fees may apply.
       6. Some features require Apple’s iCloud services; fees and
           terms apply.
Upgrading from Snow Leopard to Lion or Mavericks
To upgrade to Mavericks you must have Snow Leopard 10.6.8, Lion, or Mountain Lion installed. Purchase and download Mavericks (Free) from the App Store. Sign in using your Apple ID. The file is quite large, over 5 GBs, so allow some time to download. It would be preferable to use Ethernet because it is nearly four times faster than wireless.
     OS X Mavericks- System Requirements
       Macs that can be upgraded to OS X Mavericks
         1. iMac (Mid 2007 or newer) — Model Identifier 7,1 or later
         2. MacBook (Late 2008 Aluminum, or Early 2009 or newer) —
             Model Identifier 5,1 or later
         3. MacBook Pro (Mid/Late 2007 or newer) — Model Identifier 3,1 or later
         4. MacBook Air (Late 2008 or newer) — Model Identifier 2,1 or later
         5. Mac mini (Early 2009 or newer) — Model Identifier 3,1 or later
         6. Mac Pro (Early 2008 or newer) — Model Identifier 3,1 or later
         7. Xserve (Early 2009) — Model Identifier 3,1 or later
To find the model identifier open System Profiler in the Utilities folder. It's displayed in the panel on the right.
Are my applications compatible?
         See App Compatibility Table — RoaringApps.
Upgrading to Lion
If your computer does not meet the requirements to install Mavericks, it may still meet the requirements to install Lion.
You can purchase Lion at the Online Apple Store. The cost is $19.99 (as it was before) plus tax. It's a download. You will get an email containing a redemption code that you then use at the Mac App Store to download Lion. Save a copy of that installer to your Downloads folder because the installer deletes itself at the end of the installation.
     Lion System Requirements
       1. Mac computer with an Intel Core 2 Duo, Core i3, Core i5, Core i7,
           or Xeon processor
       2. 2GB of memory
       3. OS X v10.6.6 or later (v10.6.8 recommended)
       4. 7GB of available space
       5. Some features require an Apple ID; terms apply.
This, Adobe Flash Player 12.0.0.70, is the current version of Flash. It should work with Snow Leopard or later.

I am trying to connect my mac book pro to the tv via a mini display port and a hdmi cable, the only picture that is on the tv screen is the background picture on my computer, any suggestions?

I am trying to connect my mac book pro to the tv via a mini displayport to a hdmi cable, the only picture on the tv screen is the background picture of my mbp, does anyone know what I need to connect to my samsung tv ?

Hi there. I also bought an iWires mini Display port to HDMI cable and have an LG LED/LCD TV. I plugged it in to my MB Pro and followed the very small writing that came in the package and got both audio and video going. You need to change the audio settings from within System Preferences on your Mac to select your TV as the audio output.
My concern is the data latency - do you experience a delay between moving your mouse on the MBPro and the TV displaying the movement? It is only a fraction of a second, but certainly enough to be annoying, especially in a cable as expensive as the iWire.

How do I use a VGA adapter with my MacBook Air when it has no mini display port?

I bought this http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=200968578311 to connect my MacBook Air to a monitor but it only works in a mini display port instead, and my MacBook Air doesn't have one. What kind of adapter can I buy instead? It looks like lots of adapters are wrongly described on eBay as fitting all Macs when they don't Help gratefully received!!

If your computer has a Thunderbolt port, plug it in. Otherwise, check what type of display port your computer has and get an adapter for it.

Problem with Mac Pro Video Playback Stutter

I just purchased a new Mac Pro (2.66 GHz Quad-Core Intel Xeon with 6GB of Memory) and I'm having an issue with video playback. Whenever I play videos (in Quicktime, online, or in iTunes) the video will freeze briefly every few seconds, causing an annoying stutter that drives me crazy. Sometimes if I restart the computer the video will play normally, but not always. It is quite frustrating for me to have this issue, because I do a lot of video work and would also like to use the machine for watching movies on the Cinema Display I got with it.
Does anyone have any idea what might cause a problem like this? I got the NVIDIA GeForce GT 120 card with 512 MB of VRAM. Thanks in advance for any help.

.... will be interesting to see if improved drives help close the gap but 20% (most of the time, drivers will show 5-10% at best in a single jump, in some apps).
Having looked at and used alternatives, helps gives me some perspective. I use to assume or think QuickTime was or must be "it" but there are other apps that can play back video with more finesse, more user control. Maybe why QuickTimeX is getting some buzz.

The Mac Pro 3,1 has error correcting code memory and memory problems are very distinctive. That is not a memory problem.
It is complex and puzzling. What other symptoms are you seeing?
The error you got is that processor(s) were no longer responding to interrupts. This could be caused by a bad processor, or other Hardware problems, including a bad graphics processor. It is possible that a bad PCIe card could be involved.
This error does not happen in a normal Mac OS X 10.6.8 kernel. But you are not running a normal Mac OS X kernel, because you have added several invasive kernel extensions:

com.digidesign.iokit.DigiDal 8.0.3f1
You should first be certain that each and every one of them is the correct version for this version of Mac OS X. If that does not solve the problem, you will need to remove them all, then slowly add them back over time, keeping track of when your problems recur.

1st Generation Mac Pro 2.66 dual Core(4 cores total) 5gigs of RAM

I'm still on Logic 8/Tiger. All running very well. Typical projects run about 30 tracks. Use lots of Vi's Omnisphere, Trillian, and RMX included.
Wanting to move to 10.6.2/Logic 9.1. Is my first generation Mac Pro up for the upgrade? Will I still have plenty of juice?
4 drives(OS, audio, samples, and backup)
Thanks for any input!

I also have a similar set-up but with 8 GB's RAM. I kept the old HDD with the Leopard 10.5.8 and Logic 9.02. Installed a new HDD then did the upgrade. To be honest, it was a PAINFUL process re-loading in all of the software plus updating the software! But, for me at least (knock on wood), I've had no problems with Snow Leopard and Logic 9.1. My first "test" was to run my lastes sequencing project which has a total of 30 virtual instruments and plug-ins from various companies (Kontakt 2.5 Player, Music Lab, "External Instruments", Audio Ease's Altiverb, Universal Audio plug-ins) and all worked well. Now, to be very clear, please realize that this was only 1 "test". But I noticed right-away better usage of the CPU than the previous version. For the previous versions (Leopard 10.5.8 with Logic 9.02) of this one "test" I had to set the buffer to 512 in order to do a problem-free mix-down. But with the upgrade of Snow Leopard/Logic Pro combo, I was able to mix down this project with a buffer setting set to 128. (I'm quite happy with that setting.)
FYI, I'm using Logic Pro 9.1 in 32-bit mode. I tried the 64-bit mode, but some of my plug-ins didn't work in that mode (Music Lab's RealStrat and RealLPC, which I tend to use frequently.) But I'm happy using 32-bit mode, especially using Native-Instrument's Kontakt 4.04. Again, all works well.
Just thought I would share a positive experiece with the upgrades. Good luck with your decision.

Monitor problems with Mac Pro and Leopard

I can't turn energy saver off.I have two LCD monitors connected, one 19" Viewsonic VX924 and one 30" Dell3007WFPHC . I set energy saver:Put the display(s) to sleep when computer is inactive for Never.
Yet I can turn the monitors off and back on later and it's put the Viewsonic to sleep ,but not the Dell.
I then open the energy saver system preferences again and low and behold it's changed itself back to sleep at 26 minutes.Ghost in the machine?Why doesn't it put the Dell to sleep as well?????Why does it keep changing back to 26 minutes regardless of how many times I set it to never and lock it?
I even tried just using the Viewsonic only and setting to never,I also trashed a pref file I thought was energy saver , still same behavior, this is a REALLY big hassle ,because I have to restart every time just to get this monitor back up.
Any clues?
Many thanks!

I think there are some powermanagement prefs in your account and in /Library but I also read of problems with ViewSonic VX back when the Mac Pro came out in 9/06.
I would give the SMC button a good 'kick' and see if that helps.
And when you restart, this is normal safe restart, or forced?
SMC button, this is restart button on the inside of the mac?
It's always a safe restart,the whole computer doesn't go down, it's just the viewsonic power light blinks on and off and there is not much I can do to get back up quickly, but restart. I have played with display settings and got it back before, but that's hit or miss and very time consuming.
Thanks you so so much for your help and suggestions!

SERIOUS Problem with mac pro and kernel panics

Hi guys, I have a mac pro with 6 gigabytes of RAM + a RAID 0+1 system with 4 750 gigabytes HD's. ( 2 drives work in stripped mode, and the other 2 drives mirror them )
I was experiencing some frecuent kernel panics when using final cut or trying to watch DVD's a few weeks ago. I saved some error logs then and uploaded them to my e-mail. The problem is that now the frequency of the panics is so high that the computer has turned unusable, it reaches the desktop without panics, but when I click finalcut and it starts opening , it panics all the time, if I start to open folders, it panics, anything I try = panic.
Weeks ago I made the Apple Hardware test, testing the memory a lot and the memory seemed to be fine,
Could you guys help me to identify the source of this?, I am desperate because the MacPro is my Working tool. Is there a way to check the hard drives also? ( remember I have raid 0+1 )
Here are the error logs that I managed to capture.

What you mention is really interesting , maybe I could try to benchmark the card very hard to see if I get the panics there. I will try that for sure, because my RAID wasn't actually a 0+1. It's what they call a RAID 10 , ( two groups of mirrored drives, + striped )
It's like this post in macosrumors, but instead of two groups of striped disks, the big group is striped, and I got two smaller mirrored groups.

And I think that sould be working just fine without the RAID PCI-X card right ? ( maybe I'm wrong here , that's why I need your input guys . )

My 2006 Mac Pro (2.66 Dual-Core) graphics card has died on me...

After the loading screen, I usually get some form of this (Screen flickering and repeating itself) so I assume this is due to my graphics card not working properly?
I have a GeForce 7300 GT in my Mac Pro now and I'm wondering what to do now? Since I need a new GC, I might as well upgrade so what is the best card my computer can handle right now?
Also what are my other options if I wanted to upgrade my processors?
Any help is appreciated.

Every Mac Pro model running 10.6.4 or later can accept the Apple/ATI 5770, which uses one aux power cord. In the Mac Pro 1,1 (2006) or Mac Pro 2,1 (2007) they run slightly slower than their full rated speed due to PCIe 1 slots.
Be sure you get the version with Apple firmware, or it will not work under Mac OS X. Flashed PC cards will not light up until Mac OS X is fully loaded and running, making them useless when debugging.

Mac Pro 2.66 Dual Core Intel Xeon (April 2007) - Hard Drive Upgrade

My hard drive is making rather worrying clicking noises so I think it's time to (very quickly) pick up a new drive.
I'm a little confused about what kind of drive I should order. The drive it came with is a Seagate Barracuda ATA. Would anyone be kind enough to advise if I would be able to use an SATA II drive? I'm looking at the WD Caviar Black 1TB as they seem to have good reviews.
Any help would be greatly appreciated...

Please excuse my ignorance but when I look at my drive in about my Mac it says ATA. There wouldn't be any issues given this is an older Mac Pro from April 2007?
There is an ATA section in System Profiler (from "About This Mac"'s "More Info" button), but it for the optical drives. The hard drives are in the "Serial-ATA" section.

Problems with Mac Pro & ATI Radeon 1900XT

I conect 2 Apple 20"Cinema display to a Mac Pro with ATI Radeon 1900XT, and I only get one of the screens to work. The other indicates with the Led light switching in and out that it won't recognize the video signal. I have restarted the V RAM pressing RP Comand+Option and after the second tone of restart, it continues the same. If I disconect one, then the other switches on. Why does this happens?
Can it be because the CPU and the 2 screens are plugged to the same pluggin base?
Please, help me!!!
and sorry if I have not explain it properly, as I am Spanish, and it is difficult to explain it in English.

I have the same problem
