MacPro Early 2008 Mountain Lion can't remember monitor setting

My Mac Pro with two cinema displays and Mountain Lion starts with a "default" display setting. That means, display one and display two change after restarting the system. The OS is unable to save my settings!?

I'm largely in the same boat. I'm running 10.6 and I bought both my computers on the cusp of the capability range apple listed. I had no way of telling if they fell in the right category. I looked for something that listed serial number ranges or some kind of app that would tell me if they would be compatible but found nothing that was definitive. I even called Apple and they said it sounds like my computers will be fine. Saying things like "Mid/Late 2007 or newer" is hardly precise. Needless to say I bought my Macbook Pro in mid 2007 and my Mac Pro in early 2008. Both have turned out to not support 10.8. I have no problem with that but would like to at least upgrade to 10.7. 10.6 is still available via phone sales but not 10.7. Very fustrating.

Kernel Panic MacPro Early 2008 with Lion 10.7.5

Hello,
I have a Mac Pro (Early 2008) and for the past few months I have been getting regular (but intermittent - like every few days) kernel panics and I thought I should try to get to the bottom of the problem.
I seem to recall that they started happening after a software update for OS X Lion, but perhaps not.
Here is the report:

Macpro early 2008 with lion

I have heard that the early 2008 mac pro will run slower with lion installed. Anyone had this experience? Thanks.

Maybe your choice of reading? Tried this:

And the real underlying question deals with CS6, the OS is really of secondary concern.
But having 24GB on 2008 costs more for those 4x4GB FBDIMMs which is a shame but something you want if you aren't there now.

Hi, I have a refurbished upgraded macbook with 320 GB Disk, 4GB Memory and running Lion OS v 10.7.5. This satisfies the second part of the requirement for installing OS X Mavericks (10.9) but happens to be an early 2008 piece. Can I somehow install 10.9

Hi, I have a refurbished upgraded macbook with 320 GB Disk, 4GB Memory and running Lion OS v 10.7.5. This satisfies the second part of the requirement for installing OS X Mavericks (10.9) but happens to be an early 2008 piece. Can I somehow install 10.9? And why is apple not allowing people like me to try out this installation? Any reason that are too technical that people like me cannot upgrade and handle?
This would solve many apps to run on this.

It's mainly the video card. The Models 2,1 through 4,1 have video cards with non-upgradeable 32bit drivers. The model 5,1 Late 2008 and newer have at least the NVIDIA GeForce 9400M with 64bit drivers. Mountain Lion and Mavericks require 64bit native drivers. Mountain Lion and Mavericks no longer support Intel's GMA 950 or GMA X3100 graphics processors.
While Lion used some 32 bit and a lot of 64 bit code, Mountain Lion and Mavericks are pure 64 bit, which excludes more systems than Lion did. It's not something you can add memory to, for example, as it involves the base architecture.

Upgrade Paths to Snow Leopard, Lion, and/or Mountain Lion
You can upgrade to Mountain Lion from Lion or directly from Snow Leopard. Mountain Lion can be downloaded from the Mac App Store for $19.99. To access the App Store you must have Snow Leopard 10.6.6 or later installed.
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 Mountain Lion 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 to Lion
If your computer does not meet the requirements to install Mountain Lion, it may still meet the requirements to install Lion.
You can purchase Lion by contacting Customer Service: Contacting Apple for support and service — this includes international calling numbers. 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.
Upgrading to Mountain Lion
To upgrade to Mountain Lion you must have Snow Leopard 10.6.8 or Lion installed. Purchase and download Mountain Lion from the App Store. Sign in using your Apple ID. Mountain Lion is $19.99 plus tax. The file is quite large, over 4 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 Mountain Lion — System Requirements
       Macs that can be upgraded to OS X Mountain Lion
         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

MacPro early 2008 kernel panic at startup - need help!

I have a MacPro early 2008 with OS 10.7.5 and I can't get it to restart without getting a kernel panic error. I get it at the grey screen at normal startup, safe mode, and trying to boot from the original install disk. I reset SMC and PRAM and still nothing. Running the extended diagnostics last night turned up no error codes. Any ideas?
Not sure what else to try at this point other than ordering a replacement graphics card which could be a chore to find in itself. Is there anyway to confirm if that is it?
Thanks!

this is the last one I got before everything stopped.

Just bought a second hand MacPro early 2008 running Mavericks. How do I reset it to standard deleting previous owner admin account?

Just bought a second hand MacPro early 2008 running Mavericks. How do I reset it to standard, deleting previous owner admin account?
The previous owner seems to have cleared most of his stuff but I can't make changes as it's asking for the admin password!
Is there a way to reset the MacPro back as if I was logging on for the first time so that I can set it up as my computer?

The first thing to do with a second-hand computer is to erase the internal drive and install a clean copy of OS X. You—not the original owner—must do that. Changes made by Apple over the years have made this seemingly straightforward task very complex.
How you go about it depends on the model, and on whether you already own another Mac. If you're not sure of the model, enter the serial number onthis page. Then find the model on this page to see what OS version was originally installed.
It's unsafe, and may be unlawful, to use a computer with software installed by a previous owner.
1. If you don't own another Mac
a. If the machine shipped with OS X 10.4 or 10.5, you need a boxed and shrink-wrapped retail Snow Leopard (OS X 10.6) installation disc from theApple Store or a reputable reseller—not from eBay or anything of the kind. If the machine is very old and has less than 1 GB of memory, you'll need to add more in order to install 10.6. Preferably, install as much memory as it can take, according to the technical specifications.
b. If the machine shipped with OS X 10.6, you need the installation media that came with it: gray installation discs, or a USB flash drive for a MacBook Air. You should have received the media from the original owner, but if you didn't, order replacements from Apple. A retail disc, or the gray discs from another model, will not work.
To start up from an optical disc or a flash drive, insert it, then restart the computer and hold down the C key at the startup chime. Release the key when you see the gray Apple logo on the screen.
c. If the machine shipped with OS X 10.7 or later, you don't need media. It should start up in Internet Recovery mode when you hold down the key combination option-command-R at the startup chime. Release the keys when you see a spinning globe.
d. Some 2010-2011 models shipped with OS X 10.6 and received a firmware update after 10.7 was released, enabling them to use Internet Recovery. If you have one of those models, you can't reinstall 10.6 even from the original media, and Internet Recovery will not work either without the original owner's Apple ID. In that case, contact Apple Support, or take the machine to an Apple Store or another authorized service provider to have the OS installed.
2. If you do own another Mac
If you already own another Mac that was upgraded in the App Store to the version of OS X that you want to install, and if the new Mac is compatible with it, then you can install it. Use Recovery Disk Assistant to prepare a USB device, then start up the new Mac from it by holding down the C key at the startup chime. Alternatively, if you have a Time Machine backup of OS X 10.7.3 or later on an external hard drive (not a Time Capsule or other network device), you can start from that by holding down the option key and selecting it from the row of icons that appears. Note that if your other Mac was never upgraded in the App Store, you can't use this method.
3. Partition and install OS X
a. If you see a lock screen when trying to start up from installation media or in Recovery mode, then a firmware password was set by the previous owner, or the machine was remotely locked via iCloud. You'll either have to contact the owner or take the machine to an Apple Store or another service provider to be unlocked. You may be asked for proof of ownership.
b. Launch Disk Utility and select the icon of the internal drive—not any of the volume icons nested beneath it. In the Partition tab, select the default options: a GUID partition table with one data volume in Mac OS Extended (Journaled) format. This operation will permanently remove all existing data on the drive.
c. An unusual problem may arise if all the following conditions apply:
          OS X 10.7 or later was installed by the previous owner
          The startup volume was encrypted with FileVault
          You're booted in Recovery mode (that is, not from a 10.6 installation disc)
In that case, you won't be able to unlock the volume or partition the drive without the FileVault password. Ask for guidance or see this discussion.
d. After partitioning, quit Disk Utility and run the OS X Installer. If you're installing a version of OS X acquired from the App Store, you will need the Apple ID and password that you used. When the installation is done, the system will automatically restart into the Setup Assistant, which will prompt you to transfer the data from another Mac, its backups, or from a Windows computer. If you have any data to transfer, this is usually the best time to do it.
e. Run Software Update and install all available system updates from Apple. To upgrade to a major version of OS X newer than 10.6, get it from the Mac App Store. Note that you can't keep an upgraded version that was installed by the original owner. He or she can't legally transfer it to you, and without the Apple ID you won't be able to update it in Software Update or reinstall, if that becomes necessary. The same goes for any App Store products that the previous owner installed—you have to repurchase them.
4. Other issues
a. If the original owner "accepted" the bundled iLife applications (iPhoto, iMovie, and Garage Band) in the App Store so that he or she could update them, then they're irrevocably linked to that Apple ID and you won't be able to download them without buying them. Reportedly, Mac App Store Customer Service has sometimes issued redemption codes for these apps to second owners who asked.
b. If the previous owner didn't deauthorize the computer in the iTunes Store under his Apple ID, you wont be able to authorize it immediately under your ID. In that case, you'll either have to wait up to 90 days or contact iTunes Support.
c. When trying to create a new iCloud account, you might get a failure message: "Account limit reached." Apple imposes a lifetime limit of three iCloud account setups per device. Erasing the device does not reset the limit. You can still use an iCloud account that was created on another device, but you won't be able to create a new one. Contact iCloud Support for more information. The setup limit doesn't apply to Apple ID accounts used for other services, such as the iTunes and Mac App Stores, or iMessage. You can create as many of those accounts as you like.

MacPro Early 2008 Display/Video Card Problem

*Hello, I have a Dual Quad-Core 2.8Ghz MacPro (Early 2008) with the stock ATI Radeon HD 2600 XT 256MB Video Card. I believe I am having the exact same symptoms listed on the topic "Mac Pro 2008 Video Card Problem".*
*MacPro has been working fine. Until one day, I power it on and the display stays black. There is nothing you can do besides holding down the power button and rebooting the computer. I have tried to do this many times and the display will not come up. I have also tried resetting the VRAM and PRAM settings - still did not work. I have had my MacPro for about one year and a half. It is in very good condition (no damage/no liquid/no overheating). From time to time, you power on the computer and the display works! It is very random. I am scared to turn off the computer or put it to sleep as this can also trigger the problem.*
*I did not get the extended AppleCare (the MacPro itself already cost me about $3400!) I tested the Cinema Display and it is fine, therefore the problem is not coming from the display.*
*I went to the Apple Store and they kept my MacPro for one night. Called me the next day telling me it was going to cost me approximately $800 in order to fix this problem. They claimed that either my Bluetooth module or my Main Logic Board was causing the display not to show. I am out of warranty, and I think it is very expensive. I am doing my research online in order to try and find a cheaper solution. After reading the discussions and checking out some other websites. I have a few questions:*
*If I buy a NEW* ATI Radeon HD 2600 and install it in my MacPro - will it fix my problem?*
*OR - I also heard about the ATI Radeon HD 4870 - Is that graphic card compatible with my MacPro - will that resolve the problem?*
*Do you think I should give it a shot? Are there any other things I can try?*
*I am thinking that I should try to replace the graphic card first and see if that is causing the problem instead of replacing the Main Logic Board right away (which will cost me over $500)*
*Please let me know of any thoughts that come in mind. I really need some support. I am a college student studying Audio Engineering and I use my MacPro everyday on Pro Tools and Logic. This machine is my life.*
*Thank You,*
*Kevin C.*

Glad you solved your problem Gaunja. Here's an update on my own.
When last heard from I had diagnosed the failure of my displays to boot up to graphics card problem in my early 2008 Mac Pro with my stock ATI Radeon HD 2600 by swapping out the same card from my son's Mac Pro and seeing the displays boot up fine. Before heading off to the Apple store for a new card I reinstalled my suspect video card just to see what would happen. The displays booted up fine. Now, two weeks later, again no video display--black screens--no signal from the graphics card. I rebooted the computer several times to no avail and was, again, about to head off to the Apple store for a new card. This time "just to see what would happen" I moved the graphics card to another slot and bingo, the displays are up. What can be determined from my experience to date?
1. The graphics card is flirting with death. Like a patient unwilling to die, through a mysterious force, it rallies to live another day.
2. The slot the card came installed in is unreliable--it's dirty, there's a spec of dust in there, a contact has degraded after two years, or some other slot related fault. Note that, until the card failed for the first time, it had never been removed from it's slot, the computer was treated gently, and it operated in a very clean environment.
If anyone has another theory about what may be happening here please feel free. I fully expect the displays to go dark again at some point as my suspicions are that it's the card itself that is the problem. The two replacement cards I'm considering are the ATI Radeon HD 4870 or the Nividia Geo Force GT120. I've read that both work with the early Mac Pros. Some complain that the ATI card is noisy and expensive. Based of Gaunja's post and others I think the Nividia card will suit my needs, be quieter, and cost less. But, for now, my stock ATI Radeon 2600 lives!
Just one man's experience with the "Mac Pro display, black screen" problem.

Freeze of screen randomly on Macpro early 2008 !

Hey,
I'm owner of a Macpro early 2008 that worked fine since three years now. Since few weeks it has started to develop a strange "bug". Randomly, after few minutes, or hours, or sometimes never during the day (I shutdown my computer in evening and put it back on in the morning), the two screens plugged on Macpro freezes. When it happens, each both screens connected each one on a separate graphic card freezes but mouse cursor can still be moved on screen and computer is still running as I can still hear music playing !
I didn't find any link between applications or what I do on computer with occurence of that strange freeze !
Any ideas ? I tried to plug both screens on same graphic card thinking it might be the Geoforce graphic card that has some issues but same problem ! It looks like problem occurs more and more often these last few days. Looks like something is dying
Thanks for your ideas,
Vincèn

I've exact same problem with my mac pro 2010, but my problem still persist. My spec is 2 x 2.66 Ghz, 2 x 1TB SATA Hard disk, 8 GB of DDR3 ram 1333 Mhz. I am using a different graphic card which is ATI Radeon 5770 HD. with only 1 display and I've done intense gaming on bootcamp windows 7 64bit without any problem except with the AppleHFS.sys file.
Here is what I've done which might help you problem:
Boot into safe mode by holding shift key during bootup and see if the freeze still occurs. If it doesn't It's more likely due to your 3rd third kernel extension.
Check the Console application located at Appplications>Utilities> and see if there are any diagnostic error relevant to the freeze. (i.e. look the time stamp of each message and compare to your computer reboot time stamp.
Use disk utility and check errors for your drive. Click on the actual hard disk rather than the partition volume and click on verify disk, if there is a lot of red error message, means your disk have serious problem. Repair disk will not work if it's located on the same boot drive. But you can boot from the mac OSX installation DVD by pressing and holding C during boot.
After you booted from the hard disk, choose your language and click next. Then you will see a menu bar on top of screen. Click on utilities and then click on Disk utility. On the left hand side is a list of the disk detected by you mac. Click on the boot drive (not the volume), and check the S.M.A.R.T status of the disk. If its verified it may be okay. Then click on verify disk to check the disk for error. If you see a lot of red message from the log, it means your disk is corrupted. Try and use disk utility and click on repair disk to repair the disk.
If Disk Utility fails, there is another 3rd repair tool called diskwarrior. I've never used it. and it cost ~$99 USD for full version. Apparently it's the best software to mac to check disk error and repair.
If all your disk seems to be normal, I'd use superduper to backup your data and do a clean install of OS X from the installation disc again. If your problem persist. Try to use the apple hardware test, which is on the application installation dvd that comes with your mac, insert it into the dvd driver and boot while holding D button. When they AHT is ready, press ctrl + L to set it into loop mode. and let it run over a long period of time. It will stop when it encounters an error or hardware problem. This will detect faulty hardware, but I don't think it works on graphic cards.
If the above mentioned steps do not work for you, I suggest contacting AppleCare. I've been experience exact same problem with os x 10.6.7 SL. I've done all the above steps and problem still persist. Did a looped AHT overnight with 8 passes without encountering any error.
I am suspecting bad batch or memory modules or bad motherboard. My problem pops up randomly and hard to reproduce, sometimes I can be only all day without any issue, and sometime it procured right after boot or clean install of os x. It even happened once when I was booted from the installation DVD.
But I was using after market peripheral mouse and keyboard, I've reverted back to apply default keyboard and magic mouse to see if it is the logitech G19 or Razer Epic Naga mice that's causing the problem.
So far, I ruled out the G19 keyboard as using the Naga Epic Mice along also procured a freeze, (not sure why, but Mac detected the naga mice as a keyboard probably due to the keypad on the side.) It tried to make me identify the keyboard as I plug in the razer mic, but as it has no z and / button I could not finish the identification process.
Before that, I was using the G19 keyboard and the Razer mice simutaneously, After swtiching and using either one of them made me realsed that the Keyboard identification on OSX is not for the G19 but instead for the razer. I've been foolishly using the G19 keyboard for the keyboard identification process. I am not sure if this is the cause of the my freezing problem (2 x keyboard detected and G19 keyboard used to identify the naga epic mice).
Try the steps I mentioned above and see if it fixes your issue, and can you let me know if you are currently using any after market keyboard and mice, cause if you do... it will help me narrow down my problem before I have to wait in a long queue on line for applecare to check my problem and tell me to do things that I've already done.
Cheers.

UPS energy backup for my MacPro Early 2008. Recommend?

Hello everybody!
I want to buy a UPS energy backup for my MacPro Early 2008 with 2x 2.8ghz, 2x HD 1TB, and 16gb ram
How much power consume this configuration?, and how many VA or Watts I need to get with the UPS?
Thanks!

2008s can have high inrush current
Inrush current
Some people really want SMART UPS and others not.
I do feel 650W is marginal though 1200VA is fine, if accurate, though I tend to like to over compensate.

Is mountain lion can out put 10 bit colour? I nee to buy EIzo Monitor.

No. OS X cannot do it. If you want to drive an Eizo at its full 10 bits per channel you need to use a Windows PC.

Mountain Lion can't install but won't let me quit the installer! How can I get back to the desktop?

I was having the same problem with my iMac. Couldn't left click with the wireless mouse, i tried all the steps above to no avail. I then tried to use another mouse, this time bluetooth and still had the same problems. I decided to see if my trackpad, which sits in the corner of my desk and never gets used, and then i realize that my cat is lying on top of the trackpad which was causing my problem the whole time.
I hope your fix was as simple as mine.
