MacPro showing 3GB of 12GB installed on Snow Leopard

I have a MacPro3,1 that has 12GB memory installed (4x1GB and 2x4GB) and sometime after upgrading to Snow Leopard the system started only accessing 3GB. The System Profiler shows that all the DIMMS are present, with the correct size under the memory tab, but only 3GB in the hardware overview. I have installed a new copy of snow leopard on a separate partition, and this boots with the full 12GB, so there isn't a problem with the memory, as best as I can tell. How can I get the full memory back online on the original OS?

Usually just one pair of DIMMs will report half their size, yours seems like something I'd first do an SMC Reset.
Marginal RAM and seems like last summer we (Mac Pro owners and forum) saw quite a few.
Your Mac uses FBDIMMs. They run hot, so much so that Apple recommends waiting 10-15 minutes after shutdown BEFORE opening the side door to prevent sudden changes in air temperature. And many users boost the fans just 300-400 rpm to allow more air flow and prevent the temps from rising - the SMC can wait too long to kick in and easier to prevent in the first place.
Someone else had almost identical situation, on this forum (and not in Mac Pro section for Previous to 2009). So actually the first time I've seen someone say it was OS related. What can happen is in a RAM situation like yours, marginal RAM is causing the system to "go bad" and require reinstall due to writing data. Parity errors can also end up with corrupt files. A good reason to do preventative maintenance on a weekly basis with Disk Warrior.

Just purchased a ipad2, could not us it on my MacBook 10.4.1 - Purchased and installed OSX Snow Leopard 10.6.3 - downloaded and installed latest itunes, set up a itunes accounts and tested by purchasing an album and app, ipad does not show in devises?

I just purchased a ipad2, it would not work on my MacBook 10.4.1 I purchased and installed OSX snow leopard 10.6.3 downloaded and installed the latest itunes, set up an itunes account, purchased some music and apps. When i plug in my ipod it shows up and works, but when i plug in my new ipad the ipad screen comes up with a display of a cable and itunes but does not show in devises, i have tried all the resets and different USB ports with no success. Any ideas short of selling it on ebay or buying a new computer?

If you've already tried the usual rebooting of the computer and ports and stuff, there is only a few things left I can think of. It's possible that when you updated iTunes it didn't fully replace all the files, so I suggest just manually removing iTunes and then reinstalling it.
Try removing iTunes manually first http://support.apple.com/kb/HT1224 then download a fresh copy, make sure it is 10.3.1
It is essential that you go through Finder to remove those files it mentions. Otherwise they won't be reinstalled when you run the installer again.

Thank you for your vote of confidence, the FWIW. It's not like it is here on most forums. The official MS sites are a bit tight too.
On the issue of the points system. You don't see a lot of points given. I don't know why those seeking help aren't interested in tossing a carrot to the unpaid Apple helpers. Perhaps Apple could do more to encourage them. Except that users don't play, I think the point system is pretty good. Usually, I think points are given to decent or good solutions and helpfulness. But, you see excellent solutions given by talented individuals, e.g., V.K., totally ignored point-wise on a wholesale basis.

The hard disk has been previously checked with state of the art techniques that have confirmed that the hard disk drive is in perfect condition.

I have restored this
from a time machine partition.
TimeMachine is only a backup and restore, it won't fix issues in software and according to your information, doesn't even optimize the restore for best performance on boot hard drives.
What you need to do to regain your speed is to understand how your machine works
Why is my computer slow?

Then follow this defrag method I've outlined

There shouldn't be need to reinstall OS X fresh unless your having file structure issues which if they are should appear when in the Steps, which then a zero erase and install will cure as well as any bad sector issues, the defrag step wouldn't be necessarry on a freshly installed system obviously as the files are written all together, not in portions all over the drive.
Hope this assists.

What should i do?

Currently cannot burn a dvd or cd post install of snow leopard. Various errors to some times just ejecting the disk with no reason. System was fine prior to upgrading to snow leopard.

Fresh Install of Snow Leopard & CS5

I have a MacPro Intel early 2008 with (4) internal hard drives. I am currently running CS Design Premium CS4 from my Leopard 10.5.8 OS system.
I just purchased the following:
• A new 1-TB Internal Hard Drive (My plan is to temporarly remove one of my internal scratch drives and plug this new drive in its place. This will be the drive that I will install Snow Leopard on as well as CS5 Design Premium Upgrade as well as migrate all my existing apps to from my current boot drive. Once everything looks like it is operating correctly, I will remove the current boot drive permanently, make this new drive the default boot drive and reinstall my scratch disk drive in the slot vacated by the current boot drive - at least that is my current plan)
• CS5 Design Premium UPGRADE
• Snow Leopard Install Disk
My question is what is the best method to attack this major overhaul?
(1) Should I DEACTIVATE CS4 on the current boot disk before starting this install process?
(2) Should leave CS4 ACTIVATED on the old drive, install Snow Leopard on the new drive, then migrate all my apps including CS4, then DEACTIVATE CS4 on the new drive and then install the CS5 UPGRADE?
I am totally confused on how to properly make this transfer?
Bottom line is that I want a clean install of Snow Leopard on the new internal drive and perform a proper install of CS5 Design Premium UPGRADE on that same drive.
Thanks for any suggestions.

1. Deactivate CS4. It takes seconds.
2. Install the new drive. Install Snow Leopard.
3. If you still want to use CS4, install that followed by CS5. I would highly encourage this since if you do need to use CS4 down the road, you'll need to uninstall CS5 first as the suites need to be installed in order (unless something's changed in CS5).

How can I do a clean install of Snow Leopard with out losing iLife applications?

I bought my Macbook pro in 2009 and am currently running the Leopard software. I want to do a clean install of Snow Leopard, but I do not want to lose my iLife applications. I lost the DVD's that came with the computer. Is there any way I can do a clean install of Snow Leopard with out losing my iLife applications?
Will a regular installation of Snow Leopard allow the App store to recognize that my computer has iLife and mark it as a purchased item in my account. If it can, then would I be able to do a clean install and re-download the apps for free.
Any help would be appreciated!

1. Install Snow Leopard normally; this will keep the applications intact. An actual clean installation involves either erasing the partition or creating a blank one, and neither of those will carry the applications over.
2. The previous iLife installation won't carry over to the Mac App Store, and the Mac App Store versions are incompatible with Snow Leopard.

Clean install of Snow Leopard fails

Dear all,
As the title says my current issue is that I'm unable to perform a new installation of Snow Leopard after performing a single-pass secure erase of the Mac partition of my hard drive. However, some background to the problem is probably useful.
My troubles begin after attempting to transfer files from an USB stick to my Macbook pro. Drag/drop or copy/paste in finder resulted in nothing happening. I ejected the USB drive (which flashed to let me know the drive itself thought it had been ejected) however the USB stick did not disappear from Finder. Further attempts to eject the stick using finder did nothing. Attempting to reset Finder produced the well known "The application Finder.app can't be opened. -10810" error (see http://discussions.apple.com/thread.jspa?threadID=2135129&tstart=45). After reading through that thread and trying some of the suggestions I eventualy had to resort to a hard reset of my macbook. After restarting the macbook ran very slowly for a couple of minutes before producing the same Finder error as before (though no external drives/devices were involved this time).
After coming up against the same problem again and again I decided to verify and repair the drive using the OS X installation cd that came with my macbook pro. The hard disk itself seemed ok (S.M.A.R.T: verified), which I expected as I have Windows 7 running under bootcamp on a separate partition. (As a quick aside, Windows 7 was and still is running fine, and in fact I could successfully access and open all the files on my Mac partition from within windows. This allowed me to grad up-to-date copies of all my important files before taking more drastic action.) Verifying the mac partition resulted in a message saying the disk needed repairing. Attempting to repair the disk initially resulted in errors saying a clean install was required, though the repair succeeded on my 4th attempt. This repair failed to fix the problem and I was still getting the very slow running leading quickly to the same Finder error.
Eventually i decided my only option was to perform an erase and install of Snow Leopard. Initially I simply erased the partition using Disk Utility after booting from the install disk (default option) and then attempted to install Snow Leopard. The install failed repeatedly, alternating between 'An error has occured in the installation process' and 'Unable to install supprting files' error messages. I also tried repairing the disk after erasing and then installing with the same errors. I then performed a single-pass secure erase on the Mac partition (again from Disk Utility via the startup disk), verified the drive (finding an unassigned node error), successfully repaired the drive (twice, just to make sure) and attempted another installation, which again failed with the 'An error has occured in the installation process' error.
So I currently have a formatted Mac partition which refuses to accept a new Snow Leopard install and a fully working copy of Windows 7 running under bootcamp on a separate partition of the same disk. Is there anything else I can try other than reformating the entire hard drive and losing my bootcamp installation?

try this idea: Do a leopard install to an external disk then do a Disk Utility "restore" function to that clean partition. So you restore from the external to the internal partition. Should leave Bootcamp untouched.

Help Please! Trying to do a clean install of Snow Leopard on a new drive

I'm trying to help a family member with his Mac Mini.
He installed a new HD and we're trying to do a clean install of Snow Leopard from the DVD. I've tried booting to the DVD by holding the C key during boot up and that does nothing. I've tried mounting his HD on my Macbook and installing that way and that doesn't work either.
How do I install this if you don't have an OS on you drive to boot up to?

I was able to boot it in target disk mode by holding T. I formatted the drive as Mac OS Extended (Journaled) I've read in a couple places about GUID but I can't find that as an option on the Disk Utility.
Partition tab, Options button.
Is it possible to load the OS onto the Mini from my Macbook? I can see the installation DVD and the HD on the mini from my Macbook, but when I try to install I get a warning that it can't be installed on that volume.
It's been a while since I tried something like that, but it worked in the past. It may be complaining because the partition table is not set correctly.
I couldn't find anything about installing on another drive. I did find this old [MacFixIt article|http://reviews.cnet.com/8301-13727_7-10329087-263.html] that you might find useful if you've got an external drive. Essentially, you partition it (not necessary for what you want), make an image of the Installer and then restore the image to the external drive. You can then use that drive as the boot drive. That was for Leopard, so I don't know if it will work.

I am trying to do a clean install of Snow Leopard on an Intel Macbook Pro. (Need to partition for Boot Camp) I have done it in the past so I know it works but whenever I select the install disk as the boot device it gets stuck on the Apple logo/pinwheel.

Prety much what the question says. HELP!

If you just stuck the disk into the Leopard Mac and run the upgrader, you didn't do a "fresh install" you basically upgraded from 10.5 to 10.6 leaving all the programs and files intact.
The white Snow Leopard disk was the right one for that machine as it had Leopard (10.5) on it previously.
So you already have Snow Leopard installed, if you want to erase the entire drive (along with all your programs, files and OS X) and want to install Snow Leopard again, you hold the c or option/alt key down and boot the machine off the disk. Then use Disk Utiltiy to erase the entire drive, then quit and install Snow Leopard.
How to erase and install Snow Leopard 10.6
Once Snow Leopard is installed you log in and use Apple Menu > Software Update until clear to get to 10.6.8 and fix security issues.
Now I can't get it to do the install again.
To install Windows into BootCamp, you read and run the BootCamp Assistant located in the Applications > Utiltiies folder
It's important to change the drive format from FAT32 to NTFS before installing Windows using the Windows disk.
Windows is rather complicated to install, if you boot to a blinking line with "press any key to continue" you need to press and hold the power button down and reboot holding the Option/Alt key down to get back into OS X.

If your Windows programs are not going to be as CPU/GPU demanding, you may rather prefer to use a virtual machine instead
