Modbook with Mac OS X Leopard

Have Modbook with Mac OS X Leopard. I remove some drawing of mine and accidentally toke some file with it. When start unit it stop boot up and shows apple logo and a error sign what to do
Thanks

Sounds like OS X is corrupt. Best thing to do is reinstall.
You may have to contact the company that put together your Modbook so they can help with getting the touchscreen working again.
Csound 1 - a Modbook is a MacBook that has been rebuilt with a touchscreen display in place of the original. It's the same form factor as an older touchscreen tablet PC.

I have an iMac Intel 2 Duo with Mac 0SX Snow Leopard downloaded. Can I upgrade to the new mountain lion

I have an iMac Intel Core 2 Duo with Mac OSX Snow Leopard installed. Would it be ok to download the new Mountain Lion?

Your iMac needs to be a mid-2007 or newer model. See this page for specs supported, and assuming you meet them, you can upgrade from Snow Leopard to Mountain Lion (see step 2 on the linked page).

WRT610N - Samba Storage Problem with Mac OS X Leopard

Hello there,
I've set up a USB drive to be shared via the router (tried both a fat32 and an NTFS drive). When I login from a windows machine I can use the share point without any problems. When I try to use it from a Mac (mounted via smb://192.168.1.1/sharepoint) I can access the folders and download files. I can even create folders. When I try to copy a file onto the share point (normal file name, small file size) I get an error saying "The operation cannot be completed because you do not have sufficient privileges for some of the items." The console log says: "7/3/09 1:01:06 AM kernel smbfs_composeacl: smbfs_setattr 13, ignored "
If I try to copy the file directly via a terminal window I see this:
Macintosh-3:tc user $ cp ~/test.plist ./
cp: ./test.plist: fchmod failed: Permission denied
As I see it there is a problem with leopard trying to set permissions when copying and the router refusing. Any ideas of how to get this to work?

I found this solution in another link on this web site, I would be curious to know if this works with NTFS also.
Routers and Access Points : Wireless Routers : WRT610 USB Harddisk and Mac osx 10.5 Finally, i got it to work.
Here is my step.
1. Format the external HD with mac with the fat format.
2. plug in the HD to the router.
3. In the storage setting>Administration, create a group named "root" with r/w permission and a user "root" with the group "root. Save the setting.
4. Last, create a share on the drive. Assign the group "root" to it.
Boom! Its work now. I can use it with time machine and share my itune library. Hope this can help someone stuck with this issue.

Cannot upgrade from Mac OS X (10.4.11) with Mac OS X leopard upgrade DVD

I tried to install the Leopard today and I was unsuccessful. I was kept from proceeding to the initial install with a box that said Mac OS X cannot be upgraded to V 10.5 on your computer- Mac OS X v 10.4 or later cannot be found on your computer. At this point I can proceed and I had to quit. I brought my Macbook Pro last October just as the Leopard was being released. I purchased for a very small sum the Mac OS X Leopard Upgrade DVD but i used it today and no success. If anyone can assist me in this matter I would appreciate it. I am up to date with firmware and all other soft ware updates etc. I have also have v 10.5.1,2,3 in a folder ready to be added once I can install the my Leopard DVD

I posted a few weeks ago stating that I was unable to upgrade.
I ran Utilities and tried again to no avail.
I called Apple and they told me to backup everything and do a fresh install. Before doing that, I decided to see if the Leopard Upgrade DVD could see my backup because I created it so that it would be a bootable hard disk.
It did recognize my external disk, so I clicked on the Utilities application to see if it could see my hard disk and it couldn't. When I got back to the window that allowed me to select a hard disk, suddenly my internal hard disk appeared.
It worked, and now I'm using Leopard. I don't know if it's a workaround, but it was a lot better than deleting everything off of my computer, installing the new system, and copying it all back onto my internal hard disk.
I hope someone else will find out that this works for them...

Officejet Pro 8600 wireless print option with Mac OSX Snow Leopard?

Hi My 'old' 8600 printer died and I purchased a new one. I did not set up wireless communication with the old printer but am interested in doing so with this new one, or at least having that option.
I'm running Mac OS X 10.6.8 Snow Leopard. The installation CD that came with the new printer says it's for OS X v10.6, Lion or Mountain Lion. Is it compatible with my system?
Thanks!

Hello KelliMK, and welcome to the HP Forums, I hope you enjoy your experience!
I see you are looking into compatibility information. The Officejet Pro 8600 is compatible with Mac OS X 10.6. The software disc should allow the full install without issue.
As for the wireless setup, I would recommend following this document on HP Officejet Pro 8600 All-in-One Printer Series - Installing the Printer Software on a Wireless or W...

P2P connection drop issue with MAC 10.5 Leopard

I have P2P application which connects to FMS Server hosting with influxis.com using RTMFP protocol . The application works just fine with all other OS except older MAC 10.5 Leopard with flash player 10.3 installed.
The problem is that p2p chat, audio and video does not transmit and connection is dropped after around 50 seconds. Its same with different Computers with above mentioned OS and configuration.

It happening only on MAC 10.5 with flash player 10.3 but happens never on newer MAC or Windows PC with any browser or flash player . So it seems a old MAC specific bug.
The same issue occurs with the (Cirrus sample application ) by adobe using rtmfp at this link

3 issues with Mac Mail on Leopard...

We just bought a NEW Imac at work, but my email doesn't work correctly. The first issue is that I get no New email sound at all. I need this at to work.
Second thing is when I attach a file and send it to a PC, it embeds its and instead of attaching it. I attach by dragging and dropping it into the email. I had no problem doing this on my old IMac and mail program. It does work correctly if I actually go and locate the file and attach it, but this takes a lot long to do than just dragging and dropping. I do have "Window Friendly Attachments" checked, but it just won't work the way it did before.
The third thing is that my IN box says I have 6 new emails, but nothing is there. I can't get rid of it. It is driving me crazy.
Please help!!!!!

Hello kgoody,
I have not been able to use my mac mail for 2 months now because of the server issue. "Try later" or "Try with selected server " were at the beginning of this nightmare. Since then I have not received a single email in the inbox. I downloaded an article "How to use Gmail with Apple's Mail" by Stephen Korecky and tried to fix the problem. It did not work because the Apple Mail windows did not show what they were supposed to. I called my software wizard and he said he will have to come and fix it. He did not show up yet. It is very frustrating.

Are Director 12 projectors NOT compatible with Mac OS X Leopard (10.5.8)?

I have a user running Mac OSX Leopard (10.5.8), and when he launches the software it says "this application cannot run." It then takes him to the adobe shockwave 12 download page.
The projector is build on Adobe Director 12. It loads fine on versions as old as 10.6.8, and the most recent ones.
Anybody else have this issue or know anything about it?

Well, in case anyone else was looking for an answer...
Turns out D12 Mac projectors require minimum 10.6 (D11.x was minimum 10.4).

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!

Issues with Mac OS X Leopard installation disk

AD account Login problem with MAC 10.6.8

Hi All,
We have around 50 odd MAC that are connected to windows server 2008 R2. the user were logining in to these MACs using their AD account. Recently few of the random MAC did not allow the user to login using their AD account.When analyzed though the MAC shows that it has connected to the Domain and the server is active with green button it has unbind itself from the server.I had to login in as local user bind the MAC back to get this resolved.
Now the same has started happeneing for most of the MAC that we have and every morning I have login as local Admin and unbind / bind the MAC with the server. this gets reset once the user reboots or shutsdown.
Have tried with few of the below solution but nothing helped:
Solution 1:
<key>mdns_timeout</key>
<integer>2</integer>
The integer value is in seconds; changing it to at least 5 should allow the Mac OS X client to reconnect to the Active Directory domain after a network interruption. In some configurations, a larger timeout value may be required.
You can change this value by using the sudo command and a text editor to edit the preference file directly. Or you can use the Terminal command below, making sure to enter it all on a single line:
sudo /usr/libexec/PlistBuddy -c 'Set :mdns_timeout 5' /System/Library/SystemConfiguration/IPMonitor.bundle/Contents/Info.plist
Solution 2:
I have seen all of the probable solutions and tried everything and still I am getting issues with 10.6.6 and after rebooting the Mac gets unbind. Or the Mac gets Network Accounts Available even when not accessing the list of users from AD. But the thing that I have done that has solved all my issues with AD on the Macs is to uncheck the box to search on all domains. For some reason I am seeing that when the Macs have this option checked, it searches through out the forest on the same domain controller more than once, so AD stops the handshaking of the authentication.
I hope this helps like it did on our Network, since then I have not seen the Macs lose the binding or slow SMB.
If you've tried this please let us know.
TIP: Uncheck Allow Authentication from any domain for Mac AD problems
Wednesday, April 20, 2011
Steven Wells sent a fix and an explanation of problems with Macs losing their binding to Active Diretory:
Unchecking "Allow authentication from any domain in the forest" is working at our college. We have been beating our heads on this for about 2 terms, with no understanding of why it works in some places and not in others. When we found this working, our IT guy said that the Security SID is being duplicated, when it looks in other domain forest, and that is what is causing the problem. This is the first time I have found an explanation for the problem.
If you've tried this approach please let us know.
Solution 3:
Solved it. Create a file in Textedit with the name 'auto_master' (no file extension) with the following contents:
# Automounter master map
+auto_master # Use directory service
/net -hosts -nobrowse,hidefromfinder,nosuid
/home auto_home -nobrowse,hidefromfinder
#/Network/Servers -fstab
/- -static
Place this in /etc/ folder
Hope this helps

TIP: a Kerberos fix for OS X 10.5 and 10.6 binding to Active directory
Friday, November 11, 2011
Mehdi Mafi forwarded a fix he found for problems with Leopard and Snow Leopard binding to Active Directory:
This was taken from Dane Riley's imaging building for DeployStudio.
With Mac OS X Leopard every Mac is now running a KDC (Kerberos Distribution Center). Basically each imaged machine is using the same security certificate and hash. Deploying a single image will deploy the same KDC to every system. This [Apple] article covers how to reset the local KDC so that each system is unique. Basically, do the following:
Launch Keychain Access
Search for com.apple.kerberos.kdc and delete all 3 items
Using Terminal type sudo rm -fr /var/db/krb5kdc
After deployment, perhaps using Apple Remote Desktop to all systems, re- establish the KDC by typing sudo /usr/libexec/configureLocalKDC
If you've tried this approach with Mac OS X 10.5, 10.6, or even Lion, please let us know. .
TIP: More on a kerberos fix for AD binding problems
Monday, November 14, 2011
Mehdi Mafi updated his Friday report about Mac OS X 10.6 problems binding to Active Directory:
You may want to add this. If the Mac keeps unbinding from AD (people can't log in to a Mac), here is how to fix it:
Unbind it from Domain
Launch Keychain Access
Search for com.apple.kerberos.kdc and delete all 3 items
Using Terminal type sudo rm -fr /var/db/krb5kdc
Re-establish the KDC by typing sudo /usr/libexec/configureLocalKDC
Bind it to domain again ( When you bind, uncheck allow authentication from any domain in the forest in: Directory Utilitiy-> Advanced Options\Administrative ) this fix the issue that sometimes it can' find AD under search space.
If you tried this please let us know.
Solution 5:
For Snow Leopard AD login issues, use upper case domain
Solution 6: for .local
To create this StartupItem, create the following directory as root:
/Library/StartupItems/FixADAuth
Then chown it to root:wheel and chmod it to 755. These must also be the owner/permissions on the two files it will contain, below:
Contents of our /Library/StartupItems/FixADAuth/FixADAuth:
#!/bin/bash
. /etc/rc.common
date > /var/log/FixADAuth.log
n=0
AuthSuccess=0
while [ $AuthSuccess != 1 ]
do
id Administrator && AuthSuccess=1 || networksetup -setsearchdomains Ethernet "Empty"; networksetup -setsearchdomains Ethernet middlewich.local; n=$(($n+1))
done
echo Authentication successful: $AuthSuccess >> /var/log/FixADAuth.log echo Operation count: $n >> /var/log/FixADAuth.log
date >> /var/log/FixADAuth.log
Contents of our /Library/StartupItems/FixADAuth/StartupParameters.plist:
Description = "Fixes Active Directory authentication issue";
Uses = ("Disks");
Obviously you'll need to change "middlewich.local" to your own domain name (and the network interface name if your connection is wireless). The script checks to see if it can see the user "Administrator" on the domain, as he's a fairly common bloke, but if you've renamed yours for security reasons then pick another one. I've also included some logging functionality for debug purposes, so you can verify how well the script is working if you need to and time it in your environment before telling the users how long to wait. The /var/log/FixADAuth.log file will contain the date/time the process started, the success variable set to 1 (just to verify), how many DNS operations were required to fix the problem, and the date/time it ended. For us the time difference is normally about +30-40 seconds with around 120-180 operations taking place. Once you're happy with the script, you can strip it down to its bare functionality if you like, like so for us:
#!/bin/bash
. /etc/rc.common
AuthSuccess=0
while [ $AuthSuccess != 1 ]
do
id Administrator && AuthSuccess=1 || networksetup -setsearchdomains Ethernet "Empty"; networksetup -setsearchdomains Ethernet middlewich.local
done
I hope this helps someone!

https://discussions.apple.com/docs/DOC-4053
The subject of buying/selling a Mac is quite complicated. Here is a guide to the steps involved. It is from the Seller's point of view, but easily read the other way too:
SELLING A MAC A
Internet Recovery, and Transferability of OS & iLife Apps
Selling an Old Mac:
• When selling an old Mac, the only OS that is legally transferable is the one that came preinstalled when the Mac was new. Selling a Mac with an upgraded OS isn't doing the new owner any favors. Attempting to do so will only result in headaches since the upgraded OS can't be registered by the new owner. If a clean install becomes necessary, they won't be able to do so and will be forced to install the original OS via Internet Recovery. Best to simply erase the drive and revert back to the original OS prior to selling any Mac.
• Additionally, upgrading the OS on a Mac you intend to sell means that you are leaving personally identifiable information on the Mac since the only way to upgrade the OS involves using your own AppleID to download the upgrade from the App Store. So there will be traces of your info and user account left behind. Again, best to erase the drive and revert to the original OS via Internet Recovery.
Internet Recovery:
• In the event that the OS has been upgraded to a newer version (i.e. Lion to Mountain Lion), Internet Recovery will offer the version of the OS that originally came with the Mac. So while booting to the Recovery Disk will show Mountain Lion as available for reinstall since that is the current version running, Internet Recovery, on the other hand, will only show Lion available since that was the OS shipped with that particular Mac.
• Though the Mac came with a particular version of Mac OS X, it appears that, when Internet Recovery is invoked, the most recent update of that version may be applied. (i.e. if the Mac originally came with 10.7.3, Internet Recovery may install a more recent update like 10.7.5)
iLife Apps:
• When the App Store is launched for the first time it will report that the iLife apps are available for the user to Accept under the Purchases section. The user will be required to enter their AppleID during the Acceptance process. From that point on the iLife apps will be tied to the AppleID used to Accept them. The user will be allowed to download the apps to other Macs they own if they wish using the same AppleID used to Accept them.
• Once Accepted on the new Mac, the iLife apps can not be transferred to any future owner when the Mac is sold. Attempting to use an AppleID after the apps have already been accepted using a different AppleID will result in the App Store reporting "These apps were already assigned to another Apple ID".
• It appears, however, that the iLife Apps do not automatically go to the first owner of the Mac. It's quite possible that the original owner, either by choice or neglect, never Accepted the iLife apps in the App Store. As a result, a future owner of the Mac may be able to successfully Accept the apps and retain them for themselves using their own AppleID. Bottom Line: Whoever Accepts the iLife apps first gets to keep them.
SELLING A MAC B
Follow these instructions step by step to prepare a Mac for sale:
Step One - Back up your data:
A. If you have any Virtual PCs shut them down. They cannot be in their "fast saved" state. They must be shut down from inside Windows.
B. Clone to an external drive using using Carbon Copy Cloner.
1. Open Carbon Copy Cloner.
2. Select the Source volume from the Select a source drop down menu on the left side.
3. Select the Destination volume from the Select a destination drop down menu on the right
side.
4. Click on the Clone button. If you are prompted about creating a clone of the Recovery HD be
sure to opt for that.
Destination means a freshly erased external backup drive. Source means the internal
startup drive.
Step Two - Prepare the machine for the new buyer:
1. De-authorize the computer in iTunes! De-authorize both iTunes and Audible accounts.
2, Remove any Open Firmware passwords or Firmware passwords.
3. Turn the brightness full up and volume nearly so.
4. Turn off File Vault, if enabled.
5. Disable iCloud, if enabled: See.What to do with iCloud before selling your computer
Step Three - Install a fresh OS:
A. Snow Leopard and earlier versions of OS X
1. Insert the original OS X install CD/DVD that came with your computer.
2. Restart the computer while holding down the C key to boot from the CD/DVD.
3. Select Disk Utility from the Utilities menu; repartition and reformat the internal hard drive.
Optionally, click on the Security button and set the Zero Data option to one-pass.
4. Install OS X.
5. Upon completion DO NOT restart the computer.
6. Shutdown the computer.
B. Lion and Mountain Lion (if pre-installed on the computer at purchase*)
Note: You will need an active Internet connection. I suggest using Ethernet if possible because
it is three times faster than wireless.
1. Restart the computer while holding down the COMMAND and R keys until the Mac OS X
Utilities window appears.
2. Select Disk Utility from the Mac OS X Utilities window and click on the Continue button.
3. After DU loads select your startup volume (usually Macintosh HD) from the left side list. Click
on the Erase tab in the DU main window.
4. Set the format type to Mac OS Extended (Journaled.) Optionally, click on the Security button
and set the Zero Data option to one-pass.
5. Click on the Erase button and wait until the process has completed.
6. Quit DU and return to the Mac OS X Utilities window.
7. Select Reinstall Lion/Mountain Lion and click on the Install button.
8. Upon completion shutdown the computer.
*If your computer came with Lion or Mountain Lion pre-installed then you are entitled to transfer your license once. If you purchased Lion or Mountain Lion from the App Store then you cannot transfer your license to another party. In the case of the latter you should install the original version of OS X that came with your computer. You need to repartition the hard drive as well as reformat it; this will assure that the Recovery HD partition is removed. See Step Three above. You may verify these requirements by reviewing your OS X Software License.

Can anyone please tell me which version of Photoshop Elements will download easily and run with mac 10.5.8 Snow Leopard?

I posted a question which was: Can anyone please tell me which version of Photoshop Elements will work with Mac 10.6.8 Snow Leopard. Then this window popped up saying mark this discussion with as a question and this window. I have no idea how this works. It already is a question and if I need to emphasize that, how does this window that looks like a Word editing window, help me do that?Downloading, Installing, Setting Up

You asked the question in the title area instead of the area where the body of your posting is intended to be. No fault of yours - they need to make the form clearer.
Check the system requirements for the various versions of Photoshop Elements and see which suits your system. Adobe only sells the most recent versions of their software, so if you need an older version you will need to find a vendor for it.

Why leopard DVD not installing to powerbook G4 with Mac OS X 10.3.9? Help.

I'm trying to install leopard DVD to my daughter's powerbook G4 with os x 10.3.9. During the installation process, it says unable to install 10.5, mac os x 10.4 or later could not be found.....how am I gonna do this. Please help...

gzleearl,
Once an OS has been installed, the point upgrades, such as 10.1.x to 10.1.5 (Final) 10.2.x to 10.2.8 (Final), 10.3.x to 10.3.9 (Final), 10.4.x to 10.4.11 (Final), and 10.5.x to 10.5.6 (Pending), can be downloaded for free.
If your Mac meets the Leopard System Requirements, the Full Retail Version, of the Leopard Install DVD, can be purchased at The Apple Store (U.S.), Apple retail stores, Apple resellers, and some Online vendors.
If you know what to look for a Full Retail Version, of the Leopard Install DVD, can be purchased, sometimes less expensively, at some online Apple retailers, Amazon, eBay, FastMac, HardCore Mac, etc.
As you have discovered be sure not to purchase grey, upgrade or machine specific CDs or DVDs.
Tiger and Leopard are on DVD.
The disc should look exactly like the images in the above links, and not say Upgrade, CPU Drop-in DVD, or "This software is part of a hardware bundle purchase - not to be sold seperately." on it.
Caveat Emptor!
If any are presently available, examine these items very carefully, and if in doubt, ask questions of the seller before purchase!
Leopard On eBay
Once Leopard 10.5.x.x is installed, you can use the Mac OS X 10.5.8 Combo Update to upgrade to the current version.
You may also find this Leopard Installation and Setup Guide PDF useful.
The posted RAM System Requirement is the bare minimum.
For optimum performance, more is recommended.
As a precaution, before upgrading the OS, you should create a backup of the entire system, or at least, any data you do not wish to lose or corrupt.
In addition to the Archive & Install procedure, there is also a Simple Upgrade, or an Erase & Install option.
Review the info here About Installation Options.
Specifically; "About Upgrade to Mac OS X
Upgrading to Mac OS X takes a little longer than installing it on a volume without Mac OS X, but it is the least intrusive way to install--most of your existing settings and applications are left untouched during an upgrade. In other words, you won't have to configure a lot of settings afterwards."

Note regarding ATI X1900 XT with Mac Pro, Leopard

To all who are experiencing any of the frequently reported problems with the hardware/software combination listed in the subject heading:
I purchased the ATI X1900 XT as an upgrade fro my Mac Pro in January. I never experienced any issues with the card in OS X Tiger, but several months ago I began to experience overheating issues in Windows XP (Boot Camp) when playing graphics-intensive games. The overheating caused visible graphics corruption/artifacts, graphics system resets and even spontaneous system restarts. The frequency and severity of these symptoms actually increased over time, leading me to believe that the card was either defective or that the overheating was causing degenerative/cumulative damage to the graphics hardware.
I recently upgraded to OS X Leopard, and all **** broke loose. Immediately after upgrading, I began to experience frequent graphics corruption/artifacts (in the form of spurious horizontal lines), system lockups/freezes and spontaneous system restarts. None of these issues were present in Tiger. The system became completely unreliable and essentially unusable.
It was initially a popular belief that Leopard's graphics drivers were somehow buggy or incompatible with the X1900 XT. After my experiences, I don’t believe that’s the case. I think that the issues reported are symptomatic of hardware, not software problems. Leopard is merely a catalyst. Leopard's increased leverage of OpenGL stresses the graphics hardware in ways that Tiger did not, causing an overall increase in graphics hardware temperature. I believe that the glitches/artifacts/system freezes/restarts that I experienced were not due to buggy drivers, but due to the graphics card overheating as a result of the increased load placed on it by Leopard.
I brought my X1900 XT in to my local Apple store today and asked for a replacement. Fortunately, they had one in stock, and they gave me a new card on the spot. The technician was apparently well aware of the issues, and mentioned that they have had a lot of similar problems with new iMacs.
Since installing the new card, I have experienced no graphics corruption, system freezes or spontaneous system restarts, either in OS X Leopard or in Windows XP gaming.
I would urge anyone who is experiencing problems with the X1900 XT (in either Windows or OS X) to have their card replaced by Apple - assuming that their card or system is still under warranty, that is.
I suspect one of two possible scenarios is true:
Theory #1: The Rev 1 X1900 XT is inherently flawed and has problems with overheating, which is exacerbated in OS X by upgrading to Leopard. Due to Leopard's greater leveraging of OpenGL, there is increased thermal stress placed on the card relative to Tiger. The overheating is evident in Leopard as graphics corruption/artifacts, system lockups/freezes and spontaneous restarts. The Rev 2 X1900 XT has (theoretically) corrected the problems inherent in Rev 1.
Theory #2. The thermal management system of the X1900 XT (all revisions) is inherently flawed. The card will slowly cook itself over time, and the effects are degenerative and cumulative. As the age of the card increases, so will the occurrence of graphics corruption, system freezes and spontaneous system restarts, especially when playing graphics-intensive games or running OS X Leopard.
I sincerely hope that Theory #1 is the case. I’ll be watching my system closely as I continue to use the new card, and hopefully there will be no further problems with overheating.
If theory #2 turns out to be true, then Apple has a huge PR nightmare on its hands, as each X1900 XT for the Mac is essentially a ticking time bomb that will self-destruct within months of purchase.
The funny thing is, this isn’t the first time I’ve had graphics card trouble with one of Apple’s “professional” towers. I bought a G5 several years ago when they were first released. I had problems with the stock nVidia graphics card in the form of what came to be known as the dreaded “black screen of death.” This became a commonly reported issue, experienced by many owners of the G5 in its first revision. Apple replaced my card and the problem never reoccurred. I’m hoping that I’ll be as lucky this time around.
I think it’s apparent that Apple’s batting average with graphics cards isn’t exactly stellar. It’s curious, considering that Apple offers a very limited selection of graphics options for their towers. One would think that by Apple only offering 3 graphics options, they would be able to have fairly tight control over the quality of the hardware, and plenty of time and resources to devote to testing. Unfortunately, I’ve had more graphics hardware-related problems on my Macs than any PCs I’ve ever used. That’s embarrassing, and Apple needs to do much better than this.

I replaced my G5 Quad with a Mac Pro 8-core. The Mac Pro's thermal design is far superior to the G5's. The G5 Quad's liquid cooling system has a much bigger task (IBM doesn't publish the thermal dissipation numbers on their PPCs but I suspect they are high) than the more efficient Intel Xeons. The G5 liquid cooling units are troublesome and the issue is something I think Apple is quietly solving by replacing failed liquid cooled G5's (that are still under warranty) with Mac Pros (a very smart PR move). My primary concern when I switched to a Mac Pro was issues with the X1900 XT graphics card failure rates posted on the web and in these discussions. The very latest generation of the X1900 XT (July 2007) are reported to be more reliable. Many G5 owners are still reporting failed cards. Given the much higher thermal environment and the remarks in this thread, I can now see why. The interior of a G5, especially Quad, gets too hot for this ATi card. I had the nVidia GeForce 7800 GT in my Quad. That was a very good card. Still, the issues with the ATi x1900 XT may indeed be a thermal design issue that AMD may need to either address directly, or turn to a 3rd party solution.
I installed a 3rd party cooling alternative, Arctic Cooling's Accelero S1. It's a passive system that replaces that hairdryer fan with a large heat sink. The package includes upgraded heat sinks for the power regulator (much beefier than the stock), and for each memory chip. The heat sink is a large conductive cooling assembly that uses 4 heat pipes. The vendor claims that using this system increases the case temperature by 1°C, which is easily handled by the system cooling system. So far, their claim appears to be valid. Since there's no longer a fan, you can imagine how quiet the system has become. The only installation hitch is that the black support clips were made for the PC version and the Mac Version adds a beefy support rail on the spine of the card. The workaround is to trim off the lower tang of the clips so they just rest against the support rail.
After reading this, I'm tempted to add the "Turbo" option, a couple of high volume low speed fans that fit on the radiator. I'm trying to "stress" the system by running SETI@Home 24/7 while doing all the other work to see how hot and how loud I can get this system. So far, no disappointments. This is the quietest workstation I've ever worked on. Even when "hot", the fans are not loud. The passive cooling system seems to work very well. I left Star Wars-Empire At War up and running in the menu for hours one day and it didn't seem to suffer from any ill effects. I have owned this system for just over a month. I will add more thermal load after I crank the system memory up to 24 or 32 GB. If there are any real cooling issues, I will find out about them next summer. I really dread the prospect of plunking down another $2k for the nVidia 4500 FX (I really don't need the 3D audio support) to get comparable video support.
