There is a place under your apple that says about this mac.
Click there.
THen on the bottom of that window it will say more about this mac, click there.
THen go to your contents window and look under hardware. There you will see a file named "firewire". Click on it. If you see information under the area Fire wire Bus than your fire wire bus is working and the problem is your cable from the computer to the Drive. If you do not see any information there or something that says, "Firewire bus not connected or unavailable than that part of your card is messed up on *********** board. If it is not the cable and your machine is under warranty, take it to an apple store and have them replace the board. (Back up your important data first!)
The simple solution with out having to have your machine repaired is to buy a PCI Fire wire card and install that. You should have a separate connection on the front of the mac that is different and check to see if this one is not working either with a new cable.

The Onyx Firewire card installed in the 1620 mixer is sending a low left channel signal back to the mixer. It use to work fine but not anymore. I have this same problem on my Mac tower G4 and powermac...


Hi there and welcome to FixYa,

Try a different Firewire cable, there maybe noise issues on the cable making it difficult for the signal to pass through. If it still fails, try unplug-replugging the firewire card. Re-install the driver.

Also, for a quicker solution to that, try cleaning the contacts with WD40 or an electric contact cleaner. Replug the cable in and out... make sure as well to check that your left channel is indeed passing signal to the Mackie processor.

Hope this helps

I want to connect to my PowerBook G4. Have the unit. Where is my firewire port?


On your Behringer Sound Sytem, the firewire port is at the back, the firewire ports are actually labeled. On the PowerBook G4, it is usually located right next to the ethernet port and it has like the Y symbol above it.

There exist a number of methods for dealing with FireWire device interference, a few of which are explored here. Switching Ports The first procedure you should try when experiencing a problem that you believe to be caused by device interference is to simply reconfigure the arrangement in which your FireWire peripherals are connected. Try switching each device to a different port, or temporarily disconnecting one or more of the devices. In particular, if you are a PowerMac G5 owner, trying switching devices from the front to back ports or vice versa. Adding an external hub In some cases, it appears that FireWire devices are not drawing enough power from the computer. This can cause a sundry of strange issues, including apparent conflicts between devices and unexpected power-offs during device operation. In these instances, adding an externally powered FireWire hub can clear things up. One of the reasons an "under-powered" situation can occur is that different Mac models have varying power capacities available through their FireWire ports. PowerBooks and iBooks have the least, generating around 7 watts. The iMac G5 also generates a relatively low amount of FireWire power, sharing 8 watts between its two FireWire 400 ports. The Power Mac G5 shares 15 watts between its one FireWire 800 port and two FireWire 400 ports. Place devices on different FireWire busses/Isolate the iSight Similar to the above procedure, adding another FireWire bridge -- via an extra PCI-based FireWire adapter or another means -- can eliminate conflicts from devices that reside on the same bridge. Power cycling the system Simply cycling the power on your system may be enough to temporarily eliminate a few FireWire conflict issues. Shut down your Mac, and disconnect all FireWire devices as well as the computer's power cord. Leave the system off for about 10 minutes, then plug it back in. First turn your Mac back on, then re-attach the FireWire devices one at a time and check for the conflict to resurface. Disconnect specific FireWire devices (especially iSight) to check for conflicts As noted above, the most common cause of interference is Apple's own iSight. In case after case, simply disconnecting this single device has eliminated problems with other FireWire devices. Other devices often implicated in FireWire conflicts include video-related devices; cameras, the EyeTV, video decks, etc.
Disconnecting the iSight has proved particularly successful for an issue where the iPod disappears from the Desktop and from the iTunes playlist, while the iPod status screen cycles from the Apple logo to a "Do not Disconnect" message over and over. The exact reasons why the iSight causes more than its fair share conflicts with other FireWire devices are many, and sometimes unclear. One potential source of conflict, however, could be the unit's high bandwidth usage. The iSight captures video at a 640 x 480 pixel resolution, at 30 frames per second in millions of colors. Such throughput uses a significant chunk of the standard FireWire port's 400 Mbps bandwidth. As such, when other devices are connected, the bandwidth requirements for satisfactory performance may not be met. Try disconnecting all FireWire devices, then adding them back one by one and repeating the originally failed operation to check for conflicts. Apply the latest updates Make sure that your FireWire drives are using the latest firmware (check the manufacturers' Web site) and the most recent iPod update has also been applied. Of higher importance, if you have an iSight, is the iSight 1.0.2 updater. In a large number of cases it has resolved conflicts caused by the camera. Re-apply the most recent Mac OS X combo updater In some cases, re-applying the most recent combo updater can resurrect seemingly defunct FireWire ports and allow devices -- drives included -- to be recognized again. The most recent combo updater is available from Apple's download page. Clear caches Try using a tool like Tiger Cache Cleaner or Cocktail to remove potentially corrupt system caches. Restart, then check if your FireWire devices are recognized.

Firewire problem


this sounds like you could have blown the firewire port on the mac, this can happen if you plug in and out, even though it is supposed to be hot swappable. if nothing shows up on the firewire port but does show up on other ports on other computers then that could be the problem. its back to base with apple for a repair.

Hello Burnolid,
Well, yes, if you have an AGP PowerMac G4 then any AGP video card will FIT into that AGP port.... The question is to know if that card is Mac Compatible ?
Where did you get the card ? Did you get it our of another mac ? or from someone who got it out of a Mac, then yes, it should be compatible with any Mac with a AGP port.

Monitor does not come on


The video card you used may work for the 2nd computer but not for the 1st because of the system requirements. They might be different simply because they are different models. check which video card is RECOMMENDED, NOT MINIMUM, and get the recommended video card.
However, if it is the right video card, then get it checked at a pc shop, like pcworld or somewhere like that and see what they think of it.
