Mac Pro Health Hazard?

Hi,
I had purchased a Mac Pro 2.66 Intel in 2007. I had noticed an unusual smell every time I powered up my Mac Pro for the first couple of months. Being a Graphic Designer, I work up to 10 hours in front of my computer each day.
I had read an article online (http://news.cnet.com/8301-13579_3-10055928-37.html), which says that Mac Pros emit benzene. And benzene is known to have adverse effect on White Blood Cells (WBC) (http://www.sciam.com/article.cfm?id=even-at-low-levels-benzen).
I do a Comprehensive Full Body Health checkup at the hospital every year. The results were normal until 2006. The 2007 and 2008 results showed that my WBC count has lowered. There was no change in my diet or work habits except for the New Mac Pro.
PLEASE, I NEED HELP!
Should I get rid of my Mac Pro and buy something else?
Or is it safe to continue using my Mac Pro?
Thank You

Apple has already announced they did extensive testing and found no evidence of a health hazard from using the Mac Pro. The existence of or cause of the announced problem is unclear at the moment. The news report was from a French researcher, and thus far there's no confirmation or corroboration of any claim of benzene emissions from the Mac Pro. As the article states Apple is still looking into the report.
The fact that your WBC has lowered means nothing in and of itself. It certainly isn't proof that there is a problem with the computer.
Whether you sell the computer is only a decision you can make.
FWIW, you may not have a 2007 model. The one you have is a 2006 model. Open System Profiler in the Utilities folder and check your MachineID. The 2007 models have an ID of 2,1. If yours is 1,1 then it's actually a 2006 model.

Clean air issues with a mac pro

have any of you peeps battled with the simple problem of air quality around a mac pro. my machine exhausts so much hot air and fumes (it's always done this, i know there's no technical problem, i'm just super-aware of air quality, do a lot of yoga etc)
any ideas or solutions? at the present i have the tower in a walk-in cupboard but the build-up of heat and fumes in there after a three or four sesh is fantastic. anyone got any tips for safely (and cheaply) treating the air in the cupboard? (is it even recommendable/safe for the mac to breathe it's own air like this?)

I wouldn't be worried about it. It's literally just warm air. The CPU cores heat up, the heat is transferred to solid metal heat sinks, and that warm air is just lightly blown away from the computer via perfectly normal fans. It's the same air that is already in your room, just warmed up. Nothing is added to it, your computer isn't aspirating anything and outputting any fumes of any kind.
I'm not as sure as you are. There are some electric motors in there (cooling fans) that probably can produce (tiny amounts of) ozone. Also, the other day I installed a new PSU (Power Supply Unit), and when it came out of the box, it had a strong smell of fresh paintsolvents to it. And some fumes are smellable long before they get to a nasty level. If you are really seriously paranoid you should somehow lead the air from the computer to the outside via some sort of hose... ?
Exactly the same thing is going on all around you whenever your house or studio is warmed by the sun (not very often in London...), and the metals in the construction of the building warm up and give off heat. Something would actually have to burn,
Or just evaporate...
as in literally reach a burning temperature in order for any kind of chemical reaction to occur that will produce fumes of some kind.
But if that happens.. your computer is broken and you have a fire hazard and immediate danger to deal with.
Actually this happened to me once in the studio, when I installed what turned out to be a dodgy RME PCI card in a G5 some years ago. A few minutes after turning the computer on, I smelled a very acrid burning smell which was quite alarming and so I immediately had to hard-shutdown the computer and disconnect it from the power, real fast. As soon as I determined that it was indeed coming from the G5 and not somewhere else, we opened all the windows and left the room for some time, just checking to make sure nothing was on fire.. because the burning smell did at least seem quite toxic. Once that was over, took the card out and indeed it had started to fry, so who knows what kind of chemicals were coming out in the fumes.
But I point that out only to make the reminder that it really just comes down to chemistry and physics.. In that case, yes, there were potentially dangerous fumes because a temperature was reached which caused actual burning to occur - an actual chemical reaction - which produced fumes. However, the warm air that comes out of your computer under normal operation is really just that - warmed up air, the exact same air that is in the room already.. If it were producing fumes of any kind, even in trace amounts, then that would mean that the components responsible for the fumes would actually be chemically reacting and thus would actually be transforming chemically over time with regular use and wouldn't last long.
Or it is marginal evaporation. Some fumes (especially paint solvents) are smellable even at a non toxic low concentration of a few ppb (parts per billion).
"New computer smell."
My 'old' G4 doesn't smell at all, even with my nose to the motherboard I don't smell anything anymore. My newer machine does, however. It still has to "dry up".

Mac Pro 2008 having boot issues...

Hi,
My Mac Pro is having boot issues,It occasionally gets stuck when I turn it on and the fans go up a bit then I just get a grey screen, sometimes just shutting down and restarting works and sometimes not. I repaired the disc though it says has no issues and repaired permissions. It still does it. if I hold down the option key and boot and select my system drive then it boots fine. Once up and running everything seems fine it wakes from sleep no problem but after a shutdown it sometimes will not boot, it's almost 50 50 chance at this point that it does not boot. I can try booting off and older back up and see if it happens. I do have two video cards and 12 gigs of ram but not sure when this started to happen but it seems to be happening more often lately.
The Mac Pro warranty is over, taking it in for service is not an option at this point. I will install Snow Leopard on a new drive and see if it still happens as a test.

88 * C is HOT
Hard drives are not much of an issue, even 4, though I don't like now that WD Black tend to run 40-42C.
I recommend everyone run SFC regardless. It should be a REQ'D background app!!!
That and Temperature Monitor or iStatPro.... but on the whole only use the minimum and no duplication, not even for checking SMART health status. "less is more" or the olde "too many cooks" approach - your system runs better, even faster, and less trouble.
Kicking the fans up 400 rpm makes a significant change in temps. But of course if it is
Hutch
Pushed in corer
Up against wall
No air flow
Direct sunlight
.... can't help much or enough

Mac Pro- Damaged Disk/Permissions - Disk Warrior unable to fix, please help

Hey, I am really hoping I can solve this over the discussion board. My Mac Pro 1,1, with OSX 10.6.2 installed, has been acting up really badly lately. Random crashes, really slow, and my Radeon XT1900 is about to die, I think; the fan almost never turns off.
But the main issue I'd like to address is my damaged home disk. I booted up from the install disk and used Disk Utility to "Verify and Repair Disk" on my home disk. It said that the "Header has some minor damage," the repair finished and DU reported that it had repaired the volume and everything was fine.
However, after booting up from the HD, I went back into Disk Utility and did another "Verify Disk" to double check. It came up with an error stating: "Disk Utility stopped verifying 'Home' The disk needs to be repaired. Startup your computer with another disk and use DU to repair this disk."
So I booted from the install disk again, ran Disk Utility, and it said that everything was fine. So I booted back from HD, ran DU - only for it to report the same error as before. Why is DU reporting a problem when booting from disk, but it says there is no problem when running from the install disk?
I decided to get Disk Warrior to see if that would help. I used it to "Repair Disk Permissions" and also "Check All Files & Folders". Disk Warrior then stopped saying: "An unexpected error occurred while attempting to perform the file operations. Restart from DW disc and try again. ERROR CODE (2903, -8902)."
Here are some screenshots of the errors from Disk Warrior and Disk Utility (booted from HD). image: !http://img683.imageshack.us/img683/9789/duerror.png!
image: !http://img683.imageshack.us/img683/9269/dwerror.png!
So my main question is: Why, after Disk Utility, running off the install disk, reports that it "repaired - some minor damage to the header," does it then report the "header is damaged" when booted from the system?

Don't rely on just Apple First Aid, or trust it with finding and repairing.
Sorry you had to wait this long to get Disk Warrior.
You should always run DW from another hard drive.
Install a fresh clean copy of 10.6.x on a small 30GB partition for emergency only.
you can use that to boot from to run repairs and maintenance using Apple and Disk Warrior.
Don't bother using DVDs or CD to boot from.
It sounds like you are running DW and DU from hard drives, but not clear which or from where (and when).
Always use the SAME version when repairing permissions, never use an older version OS or of Disk Utility.
CLONE your system. Always have a couple bootable backups.
Choice is Apple Disk Utility Restore; SuperDuper; Carbon Copy Cloner
If a drive does have errors, be ready to restore and have backups on hand if it comes to that.
System (OS and apps) probably only change weekly or even monthly.
You can backup /Users to its own backup partition more often, and use Time Machine plus another method there.
Personally, I tend to run DW directory repair first and sometimes only, and only then check files.
TechTool Pro 5 is what I use for checking files, disk media for weak sectors, and some other problems not covered by Disk Warrior; and, because it can run concurrently on multiple volumes and drives.
It is 'iffy' to verify a live system and get an accurate read of its health, but I'd say Disk Utility is "out of its depths, and league" when it comes to finding and repairing, and for the errors it is encountering on your system.
Isolate the sytem from data and media files and libraries as much as you can and still easy to manage.
Most errors are with system or boot drive.
Radeon X1900 needs to be removed, carefully inspected, and any dust in the vents, air intake portion and exhaust, cleaned out. Right now the only real upgrade there is the ATI 4870 for now (Apple's or flashed).

Mac Pro won't start; power supply problems?

Hi friends, I'm having some very inconvenient hardware problems. My Mac Pro system will not start up. I have done some preliminary searching for similar issues, and it seems there are too many possible outcomes for me to tell directly from their answers. I'm writing in hopes that someone has had the same experience and can offer advice.
Here's my symptoms.
• Mac Pro system, late 2009. Dual Quad-core Intel Xenon, I think. (I usually just go to System Profile, rather than memorise this crap.) Two internal drives (SSD for system, HDD for data); all other hardware standard.
• Power light indicator is solid white. No blinking.
• No startup chime and no audio bleeps
• Display is dark, no activity of any kind.
• This behaviour persists with no network connections, no hardware peripherals outside of Apple Studio display and its associated USB cable (which allows the keyboard)
Do we suspect it's the power supply? It seems to power on, and clicks to life as it does after waking from sleep, but doesn't boot. Pressing the power button again shuts down the machine instantly — no 5-second-hold required.
It could be the RAM, I guess. I have yet to do the diagnosis of removing DIMM pairs one-by-one to see if something is the problem.
Any advice you can offer is great. Thanks

There are LEDs adjacent to the RAM positions that, when lit, indicate a bad DIMM.
The side door is not interlocked, and there are no hazardous Voltages available to your unaided fingers, but components may be HOT.
A Bad DIMM will not preclude Booting. Your Mac will note the defect and attempt to boot without that DIMM. And 2009 DIMMs are independent, so losing one does not take out any others.

My mac pro's power adapter has something wrong, sometime can work, sometime dosen't, can you fix it?

my mac pro's power adapter has something wrong, sometime can work, sometime dosen't, can you fix it? i brought this mac pro last year.

No, we can't fix it. Probably live half the world away from you and don't have telephatic powers....
But you can try yourself. First, make sure the connector is absolutely clean. The gold pins on the cable end should all move freely and fully extend out. The gold pads on the Mac connector should be spotlessly clean, and the area around them, where the metal ring on the cable goes in, should be free of any debris that may impede full seating and contact.
Next, the cable on the power brick should be in good condition, without kinking or fraying. If there is any damage, only solution is replacement, it is not serviceable.
Lastly, make sure the battery is ok. Go to the About This Mac item in the Apple menu, do More Info... / System Report... and select Power on the left column. In the Battery Information, Health section, make sure the Condition is Normal. Else, will need replacement.

Turning Off CPU Cores - Cooler Mac Pro?

Using a Mac Pro in a small room raises the temperature of the room quickly and it is always hot. Does turning off 7 cores (leaving 1 available) using the CPU menubar utility make the computer run cooler? Is there anything else I can do to make the Mac Pro not run as hot?

I hope you didn't think we were being dismissive. I work in a small room on the top floor of a house which even if the house itself and the weather outside are very cool, my Mac room is too hot to stay in. So for me AC and a fan are the only options. The AC for both of us, the fan for the Mac.
I've never heard of someone trying to disable their machine in the way you are wondering about. Perhaps it can be done but just how many CPU's would you have to disable for a heat decrease? And what effect would that have on your overall system, health and performance-wise?
Then what about the heat from your display? That adds in too.
Maybe like me you can't put a regular AC in your window. I had to get something along these lines, which is noisy but works great for my needs:

New Mac Pro running Snow Leopard?

I literally picked up a new Mac Pro today at the local Apple Store and it is running Snow Leopard (10.6.4). Is this usual? I don't get the latest operating system on this puppy?

Be grateful.
You don't want Lion, not today, not quite yet.
Apple still sells 10.6.3 DVD as well as a combo Snow Leopard and Lion on USB thumb drive $69.
In the past priro two OS, there was 10.X.6 DVD but not this time.
So Apple has their giant 1GB combo updates plus another 500MB of supplemental updates for other programs and patches.
Your OEM DVD has Apple Hardware Test.
Mac Pro can still run 10.6.8 just fine.
Macs that only use Lion use network installs, .network hardware test.
Lion recovery partition though can check the health of all hidden hard drive partitions as well as repair so that is nice and for $30 you might want to TEST Lion on another hard drive at some point. Better that then splurging on 3rd party system tools.
The 2010 can take a faster processor. The limitation? still SATA2 means bandwidth and performance hit for storage hits glass ceiling. That SATA 6G SSD for instance.
Blessing in disguise to me.

Mac Pro RAID Card and Western Digital drives

I'm having huge troubles with these items.
I first installed four WD7500AYYS (Raid Edition) to build a RAID 5 and install Leopard on it. At this point, one of the drives was probably DOA and didn't show up in the bay. I then reinstalled the Seagate that shipped with the machine, then proceeded to create another enhanced JBOD raid with one of the WD drives. After a couple of seconds, RAID utility reported an error (disk about to fail and such). I then tried with another one. The process ended with a kernel panic after two hours, while RAID utility was still marking the drive for enhanced JBOD. That disk never show up again, in any bay.
At this point, I'm left with two WD drives. I can't get past the creation of a RAID set with them, no matter what. Either RAID utility reports an error, or it says the disk has been ejected, or it keeps create the RAID for hours... The later usually ends with a "force quit", or a force shutdown. During these attemps, the RAID card went missing once, then it appeared again on the following reboot. The RAID battery, which was fully charged at first, is now being "repaired" (charging ?).
I then ran AHT to see whether there was something wrong. No errors reported.
Because all four drives were Raid Edition, I thought this could be the root of the problems. So I bought a Caviar SE16 (WD5000AAKS). To no avail. It fails too, in the very same way. And now it no longer appears in any bay.
The last step I took was to remove the RAID card (connecting the iPass connector to the motherboard). Out of the five WD drives, only two RE2 (the two that still show up with the RAID card) do appear in disk utility. But disk utility never ends "writing the partition map" or "preparing for initialization".
By now, I end up with five WD drives that appear to be just dead, as if they were killed by the RAID card trying to RAID them. The only drive that works, with or without the RAID card, in any bay, is the Seagate. I didn't try to fiddle with it though (I'm reluctant to format it just to see whether I can create an enhanced JBOD raid with it).
So the question is, are Western Digital drives compatible with this RAID card ? If they do, then how a RAID card can kill them in such a way while keeping the Seagate alive ?
I'm lost in conjectures. I don't even know if/how I can bring all the WD drives back to life. I'm not sure the RAID card is faulty, I've already lost a lot of time and money, I'm not willing to buy yet another drive to see it fail too, and my Mac Pro is kind of useless as I don't want to spend time on installing/configuring everything I need on a drive that is bound to be replaced by a larger RAID 5 array.
Any help is appreciated. Thank you.

Someone yesterday or Friday, had a system with 4 x 1TB drives and Pro RAID, but in their case, it was determined later Saturday that drive bay #1 was not functioning.
Hopefully these fully retail drives, not OEMs, and I would think they are fine. They are what I would use (Sonnet Tempo only supports RE of the WD drives). Someone else, Danish?, had 3 out of 4 WD drives were DOA.
I've never had trouble buying over a dozen from OWC, so it does seem odd.
If you have SoftRAID 3.6.6 I would use that to zero the first and last 100 sectors, or you can begin to zero the whole drive and cancel at any time, just to check the health of the drive and that it can zero and not produce I/O errors.
There are two other methods for accessing and managing Mac Pro RAID, ARD and CLI
http://docs.info.apple.com/article.html?artnum=306231
Originally, only Apple drives were supported. My understanding was that this changed. But the only article I found in KB dates back to Aug '07:
Question: What drives does Apple support with the Mac Pro RAID Card and the Xserve RAID Card?
Answer: +Only Apple drives are supported with the Mac Pro RAID Card and the Xserve RAID Card.+
My understanding that 3rd party retail drives such as WD RE2 750GB, Seagate, Hitachi were supported as well since the article was written - and I can't find where I read that, but sure that I did, as this was discussed in the past.
I'd like to find an official article. Even my friend Google was helpless

Cannot send email from 3 accounts Mac Pro

My brand new Mac Pro cannot send email using Gmail, Shaw, or iCloud. At times I can send a simple test message, other times I cannot send. It seems the more data in the email, it for sure cannot be sent. The sent messages get stuck in the Out Box. Full green lights, no red lights in the connection diagnostics window. Any help in this regard will be much appreciated.

thank you for your reply, I did this with the same problem. Turns out that I went to FAQ section and went to the "Sharing" section of "system preferences" and changed my computer name by removing all spaces and apostrophe where it lists my computer name under Mac Book Pro, and problem solved.

Using a serial Wacom tablet on a Mac Pro

I have a good Wacom tablet with serial port interface that I would like to connect to a Mac Pro.
Is there some way to do this? Is there any sort of serial to usb adapter or would that not work with a Mac Pro?
Thanks for any advice.

I don't think so. See these knowledge base articles from Wacom:

Mixing Memory Mac Pro 2.66 Xenon

Hello all!
Alright I am trying to figure the best configuration that I can afford for a memory upgrade to my Mac Pro. I am looking to spend somewhere south of $200.
I currently have the following memory configuration (3GB):
DIMM Riser A/DIMM 1: 1 GB
DIMM Riser A/DIMM 2: 1 GB
DIMM Riser B/DIMM 1: 512 MB
DIMM Riser B/DIMM 2: 512 MB
I wanted to expand it quite a bit more and see on NewEgg that they are charging appx 65.00 for (2 x 1GB) and 80.00 for (2 x 2GB). It's definitely a better price per GB to get the 2 x 2GB but would I see a large performance increase?
I have been reading on the message boards that it is best not to mix memory but it is suggested to fill all the slots with the same size memory.
I guess it just kills me to take out all of my existing memory to put in just the 4GB of new memory.
Could anyone provide any suggestions?
Thank you for your time in advance!

You have 3GB, which is on the lite side.
The ideal for that model is 4 DIMMs.
Without knowing if you are a light photoshop, or what you use it for, Apple calls 4 x 1GB for FCP (and audio apps) "symmetrical memory."
And I would look at 4 x 2GB and pull your 3GB, maybe sell it once you know the new memory is fine after a month.
Are you seeing page outs? multiple swap files?
Go to folder: /var/
Maybe you are better off with faster drives, new boot drive or for scratch. A WD 10K 150GB VelociRaptor for $180 even.

Is my mac pro's nVidia 8800gt dead. B&W lines across my screen only

Hi, I run a Mac Pro 2008 oct core system. The specs are as follows:
dual 2.8GHz quad core processors
Snow Leopard with all software updates
16GB RAM DDR2 (Pre-DDR3 mac) (apple certified RAM, so won't break my warranty)
Hard drives are set in two raid arrays, there are four 1.5 TB drives, each set to pairs of raid 0 for 3 TB drives. One raid array is set to time machine the other is my startup disc.
dual DVD RW drives
N-Videa 8800GT graphics card (Shipped with my mac)
using a DVI to HDMI adapter to connect to a 40" Samsung LCD TV as a monitor (has always worked flawlessly)
I have upgraded a lot of the parts myself and have a fair amount of knowledge of how to do my own upgrades. My system today crashed on me after waking from sleep mode and attempting to use the web. Now when I try rebooting it gives me a screen that is even lines of black and white, nothing else. I do get the Apple beep noise like normal so my assumption is it isn't going to be the memory. I have cleaned off, reseated, and tried different slots with my graphics card, and both DVI ports, same effect. I am pretty sure this is the graphics card demanding to be replaced, which I have considdered upgrading anyway in the past. Most of my computer activities involve watching HD quality movies and TV shows and playing games with high graphic requirements at maximum settings, so using a top of the line graphics card is to be expected.
What I am posting here for is just getting a confirmation that other people agree with me that this is the problem so I do not waste my money on a new graphics card. Please let me know opinions, I would like to have my computer running swimmingly in the near future. Thanks in advance, I appreciate any help I can get.

Most people often seem to think that after a system freeze they don't need to repair their boot drive.
Over the years, Disk Warrior stands out as indispensable.
ie, don't rely on the restart alone to repair and fix, and you probably don't want to trust and rely on just Apple First Aid.
Boot from another drive and run Apple First Aid followed by Disk Warrior; keep backups of your system you can boot from. Clone your system with SuperDuper. Clear out system caches.
You don't need to buy Apple RAM and its prices to have certified RAM, Crucial and others are fine. Sometimes even better.
I like a fsst, small, boot drive and keep it just to OS/Apps; everything else, media files, data, whatever, on other drives. Multiple backups and redundancy. TimeMachine doesn't benefit or perform any faster with RAID, I've tried just to see.
I would slice off some space for an emergency boot drive so you can OPTION boot to that and run First Aid and other maintenance.
Then worry about hardware, and maybe run some hardware tests.
And for a good "is it software or hardware" do a clearn install of Apple OS and updates (only) - needs less than 30GB.

Can't Get MacBook Pro and Mac Pro to Network

I have a MacBook Pro (2008 - 2.5 Ghz. Core 2 Duo with 4 Gb of RAM running OS X 10.6.7) that I have been connecting to my Mac Pro (2005 - 2 2.66 Ghz Xeon with 20 Gb of RAM running OS X 10.6.7) through an Ethernet switch on my school's network. This has worked without a hitch for years, but when I upgraded to 10.6.7 recently, the MacBook and Mac Pro fail to network. On the MacBook Pro, the Mac Pro's icon doesn't show in the shared area, and on the Mac Pro, I can see the icon for the MacBook Pro, but when I click on the icon to connect, I get the message that "Connection Failed There was an error connecting to the server (name of my MacBook Pro). Check the server name or IP address, and then try again." I have tried a direct connect using the "Connect to Server" under the Go menu on both machines, using their IP addresses, but no luck. Is there something I need to re-set to get these two to talk again? I have other Macs on the same network that my MacBook and my Mac Pro can see, and both machines can connect to them. They just can't connect to each other.
Thanks in advance for any ideas you might have on how to fix this.

I fixed the problem by re-setting the default values for my VirusBarrier X6 anti-virus program.
