My mac Pro Tower shows some green and reddish lines on the monitor and gives report of unresponsive processor

And never heard of one case of AHT finding or reporting a real GPU related problem.
It does sound like the graphic card and best way to know is to swap it out, even if you have a PC card around.

I have a Power MAC G5 dual 2ghz that has a peculiar problem. The monitor will not report until the machine is stopped and started 5 or 6 times. Once booted it will restart without problem if done so from the apple menu. Swapped out all hardware

My Power MAC G5 has a peculiar problem. The monitor fails to report until the machine is started and shut down 5 or 6 times. Once it has booted it can be restarted without incident from the Apple menu. I have swapped out all of the hardware. Monitor, Memmory,Video Card and reset the PRAM. After resetting the PRAM it booted on the first attempt and I thought it was solved. But the next day it was back to starting and stopping until the Monitor came on. Does anyone have a suggestion? Thanks

It could be a bad PRAM battery corrupting your PRAM. Typically when I have monitor issues on startup it is a bad PRAM battery.

Apple's PRAM reset directions - http://docs.info.apple.com/article.html?artnum=2238
If you have a digital multimeter you can check the condition of your present battery. It should read at least 3.2V if it is the 3.6V half-AA battery type. A new battery provides 3.67 Volts DC. A bad battery provides under 3.2 Volts DC. Ideally this should be measured while the battery is under load; added recommendation from Hans777:
>I have recently found out that an exhausted battery will still indicate >3.6 V with a high internal resistance VM.
>
>Checking incircuit: powercord disconnected press PMU reset button for >about 5 sec before measuring.
>
>Checking outside: load the battery with a 1500 Ohm resistor when measuring.
Alternatively, test the battery while it is still in the computer.
If the battery is more than 5 years old, especially if you totally disconnect the computer from the power regularly, or have left it unplugged for several months at one time, it is likely the battery is dead.
Sometimes you have to do a more intensive reset of hardware management:

I have a brand new Mac Pro Tower that continually kicks me off the internet and sometimes starts up not connecting to the internet?

My brand new Mac Pro Tower that I spent a small fortune on sometimes boots up and does not connect to the internet when every other computer in my office does and other times it just kicks me straight off. My question is, is there a problem with the wi fi on these machines?

Brand new nMP Mac Pro 6,1 Late 2013.... and it is defective - the older silver tower might be easier to find parts but at least it is not 65 lbs and is something that can be taken in - which I think you really need to do.
When you run etrecheck from www.etresoft.com it can show what is installed, drivers and might help point to something on software side.
Grant is the go-to person here I think among others for networking issues.
Airport Express and signal strength, channel it is trying to use, whether the Network control panel settings are "correct" or need to be changed (even the order, what it is trying to look for and use).
If you move it to another spot or put another computer over in that general vicinity...? behaves the same.
I recall reading where the MacBook Pro model in 2012? and switched to a new chipset and some very long (huge) threads in their forum - which means also there was no real solution given.
No, should not be. And other than network tests would be booting into Apple DiagnosticsTest mode - pulls down from Apple servers.

Wireless connection to internet with mac pro tower and airport extreme base station?

Hi, I have an airport extreme base station and a mac pro tower without a airport card. My internet wireless router is a great distance from my computer so I can't connect the base station directly to the router. I've attached the airport extreme base station to the tower via an ethernet cable, the base station seems to be wirelessly connected to the home network but the browser is showing "not connected".
Please help.
Thanks

Shouldn't the Airport base station be able to connect to it wirelessly?
It might be possible, but the Ethernet ports on the AirPort Extreme would not be enabled, even if it did connect to the Thompson' WiFi signal.
As Tesserax notes, among the Apple routers, only the 802.11n versions of the AirPort Express have the capability to "join" a wireless network with the Ethernet port being enabled.

My wife and I both have the iphone and we use my macbook pro with iTunes to sync our ipods. When I do something on my iPhone it shows on hers. How do I set up her a seperate iTunes acct on my mac so she can operate independent of me?

My wife and I both have the iphone and we use my macbook pro with iTunes to sync our ipods. When I do something on my iPhone it shows on hers. How do I set up her a seperate iTunes acct on my mac so she can operate independent of me?

There's info here on setting up separate libraries and user accounts. You won't have to reload (or re-import) all the music, just copy it.
The reason I suggest separate accounts on the Mac is because if you have the two libraries under the same user account, iTunes will also open the last library that was open in that account, and you'll always have to be mindful of which library that is. If you open iTunes and find it's not your library, you'll have quit, relaunch holding the option key and select the other library.
No, you won't have to log in and out of the Mac. (If I'm understanding your question here.) Multiple accounts can be logged in at the same time. And with fast user switching, you can toggle between user accounts.
I'll admit that maintaining the two libraries gets a little tricky, because if you share all the same music, you'll have to add it to one and update the other. (That won't happen automatically.) But I think Home Sharing makes this much easier to do.
Hope that helps!

TS1362 I have a Mac Pro tower, am running osx and iTunes will not work.. It basically just stopped working after having run faultlessly for...years... I can see all the songs, playlists etc, but the progress bar will not progress..it's 'stuck'. Suggestion

I have a Mac Pro tower am running OSX and iTunes will not work. It has always worked flawlessly. I can see all my iTunes content- my playlists, my songs et cetera, But I cannot play anything. The progress bar is 'stuck'...any suggestions?

Thanks. I have been using iTunes since its inception and have never had a problem...I'm using the latest version. The progress bar is the bar that moves when you're playing a song..it just won't start when I double click on a song,..have tried quitting, rebooting etc but nothing works. Apple are useless-they have told me twice they've tried to call me 'momentarily', but I've been waiting by the phone, and they definitely have not tried to call...

Can I download and use final cut pro 7 on new mac pro tower?,or I must work with the new final cut pro x only?

can I download and use final cut pro 7 on new mac pro tower?,or I must work with the new final cut pro x only?

Disclaimer: This response assumes that a "new mac pro tower" is the new cylindrical model.
1. You cannot download Final Cut Pro 7. FCP7 is part of Final Cut Studio (2009) a.k.a "FCS3" and it was only released on a DVD set. It can still be purchased online (maybe even from Apple) for prices ranging from a few hundred to $1K and it is 5 years old and unsupported.
2. Although there are reports of systems running FCS3 on Mavericks, there are also a host of problems associated with this OS/software combination.
3. A new version of iMovie Pro Final Cut Pro X has been released which is reportedly very fast and is supported.
It's all a matter of what kind of movies you make...

Mac Pro Tower - Which Fans Cool All of What?

So I have a 2008, 2.8 GHz 8-core Mac Pro tower. I'm one of the many people who have problems with the fans. In my case, I can get really high fan speeds, and the problem seems to be due to a faulty temperature sensor. (Using iStat, it will sometimes show unreasonably high temps on a couple cores [or the heat sinks, apparently] immediately after turning it on, whether or not it's been off for awhile. Sometimes, it will even show negative temperatures, in which case the fans will really go into overdrive. Yes, I've already tried resetting the SMC and cleaning it out - nothing.)
What I've ended up doing so far is download Macs Fan Control and setting it to base the fan speeds off CPU temps that don't give faulty readings. This works really well for lowering the fan speed (and thus noise), but I understand that different fans cool parts of the system besides just the CPU. The fan names give basic descriptions, but not a lot of detail beyond that. I've been trying to find a diagram showing which fans cool which parts of the system, but I mostly get results about fan noise, or minimalist diagrams that don't tell me all I want to know. I'd like to make sure my settings are fairly optimal before I do anything intensive.
Can anyone help me with this?

I think you are "barking up the wrong tree".
The fans in the Mac Pro are controlled by Software in the System Management Controller. They make a feedback loop based on measured temperatures. If you are getting racing fans, that is probably based on Bad Temperature inputs. Fixing the temperature inputs is where you should place your energy. The fans are slaves in this process.
One possible exception: Most of the fans do have an RPM output indicator, which tells whether they are spinning properly. If the diagnostic indicates a MOT error, that is likely to be a Fan Motor that is not showing high RPMs at High speed settings, and may be defective. The power supply fans were designed by a different team, and may not have the same controls.
What SMC Fan Control and similar software allows you to do is put a new Floor under the fan speeds. They will spin faster at idle, and it is possible they may move up to even higher speeds more slowly. What is does NOT allow you to do is any actual reduction in minimum fan speeds, regardless of whether it allows you to set lower numbers.
When the numbers get extremely large, the magnitude bits overflow into what is sometimes considered the sign bit. That has no meaning in this context -- all numbers should be treated as positive numbers. That probably indicates they took a shortcut and used general-purpose routines for signed numbers that were lying around instead of writing more correct versions for positive numbers from scratch.

Using Mac Pro tower as a Time Machine backup drive

Has anyone here ever done this? My roommate and I both just got new MBPs, and rather than buying the Time Capsule, I thought I might be able to use my Mac Pro tower as the destination drive for our backups wirelessly, but I can't find any information on the topic anywhere online. If anyone has some light they can shed on this, I'd be very much appreciative.
Thanks in advance for your assistance!

Start File Sharing from the Sharing pane of System Preferences and specify it from the Time Machine pane of System Preferences on the other computer.

Using an external microphone with a Mac Pro Tower

I have a Mac Pro tower with OS 10.4.11 and I have a question regarding recording sound through an external microphone.
I own a microphone with a 1/4" jack and when I plug it into the designated input on the back of my tower, I'm not getting any sound. I've troubleshooted with a couple different microphones and none seem to work. Am I doing something wrong? Is there some sort of configuration that I have to do when using a mic?
Please help!

I'm sorry, but that's not really my area of expertise. If you are planning to use this for simple voice-recording you could try the Griffin iMic device which helps provide both pre-amplification and impedance matching between a mini-plug mic and a USB port for sound input. I've used it recording music from a boom-box to a MacBook.
The tech specs state that the audio line-level in port is:
Input impedance greater than 20,000 ohms
Input level: Max 2 V rms (+8.2 dbµ)
I would look for a mic that meets those specifications. MacSpeech.com has several microphone/headset recommendations for use with their Dictate and iListen voice recognition software. I would think that their suggestions would be useful.

A Gift Mac Pro Tower - But there are problems

I was given a Mac Pro Tower (No manual, box or anything, just the computer) that is a few years old, but was jazzed up with 8 GB memory and 2 x2.66ghz Dual - Core Intel Xeon Processors. It is running 10. 6 OS. It is obviously out of warranty, so I can't take it to the shop and expect them to fix it.
I am very confused about wireless modems or running a modem connected with a phone cord to the computer. When I connected the DSL modem I used on my G4 to the Mac Pro, it runs for a few minutes and then freezes the computer, asking me to restart it. The last time there was an error message saying "panic from CPU 2" (or something like it.) No one I have called has given me a straight answer. The computer also runs hot and I have to keep my space at 64 degrees to keep the computer genrerally happy. ATT my internet provider (@#%^#&z) has either tried to see me a new modem or new "services", even though my computer shows it already has a modem and is wireless modem capable. In fact, I can reveal my neighbors connections in the upper right hand pull down icon. Shouldn't I be able to log into ATT's internet service wirelessly since they have said I'm paying for it?
So if someone can explain what I need to do, need to buy, or not need to buy I'd be grateful.

Not all network equipment that worked with PowerPC worked with newer Intel Macs like yours.
And ISP will need to go through an activation page probably.
I switched recently from DSL when I found out the people that took over from the old company, would not work with two different Netgear ADSL modems anymore; nor would they work with Windows 8 (maybe just the activation script but seemed too much for me).
I had an old cable modem, switched to cable, but that would not work (bought in 2002) with their new equipment, but for $5/month I was fine (and get phone service through their modem) along with 24Mb service.
I went through a couple routers to get better wireless (the first cheaper unit really was not satisfactory and again felt it was worth the upgrade).
I recommend you contact Apple and for a small fee, once they check the hardware serial number on it (one reason to never ever post such ser no online btw) they can send out the OEM replacement DVD so you can at least run Apple Hardware Test.
with all the people here, you should still get great use from your new tower Mac Pro.
