Question on Firewire 400 Connection via iMac and throughput

This may be a question for an Apple person, but does anyone know if the Firewire connection on the iMac is managed by an individual I/O card, versus the system bus as are the USB ports.
The 'word out there' it is and thusly the Firewire performs better than the USB, depending on other 'stresses' on the CPU and OP SYS, etc.
Can anyone confirm this technicality?
It could be useful in selecting various peripherals.
Thanks.

Um... FireWire 400 does have more throughput than USB2, but that has nothing to do with there being a separate card or bus for it (nor is it Mac-specific). It's a difference between how the two technologies work. FW400 will alway provide more sustained bandwidth than USB2, by design. USB uses considerably more overhead in its data packets (and the 480Mbps max speed is inclusive of that overhead), CPU usage, and the delay between packets is much higher as well.
In practice, a FW400 device can transfer pretty close to the 400Mbps limit, whereas USB2 typically tops out at 160-200Mbps sustained. This is true regardless of the hardware platform, and generally it's not relevent if there's a separate controller card or one built-in.
This is also very much common knowledge and well-known and understood. It's not rumor.

Firewire 400 connection for pc?

Hello

Hi,
Many machines now don't have firewire connections except for some business machines including laptops. You don't supply what is the model of our "HP Pavilion HPE" but most likely it has few spare PCIe slots and you can use something like:
http://www.newegg.com/Product/Product.aspx?Item=N82E16815166018
There are many around, 2 ports, 3 ports, 4 ports even 5 ports. Again, please check the model of your machine before go out to buy a card.
Regards.

How to i connect my imac and my macbook so there doncuments are up to date

how do i connect my imac and my macbook so they are in sync and up to date with the same documents?

Welcome to the Apple Support Communities
There isn't a way to connect both Macs with a cable to keep your documents updated on them. However, if you need all your documents updated on both Macs, you can use a cloud service as iCloud or Dropbox to sync your documents. Preferably, I recommend Dropbox because it can sync all type of files between both computers > http://www.dropbox.com
Another thing you can do is to buy an external disk and put your documents here

Which Firewire Cable to connect an iMac and a Mac mini ???

Hi guys
What Firewire cable should I buy to connect an iMac G5 and a Mac mini G4 and use a partition on the mini as a Target Disk?
I've read something about 4 pin, 6 pin, 9 pin... 400, 800
I have no idea what type of cable I have to buy and if it makes different about performance...
Cheers!

No, you need a FW400 6-pin to 6-pin cable and they are all the same. FW800 has an entirely different connector and neither the iMac nor the mini have it. It might be called IEEE1394 or iLink on the package, but it is all FireWire 400 in stores generally. I have never seen a FW800 cable in a regular retail store.

Question regarding ONT connection via Ethernet and Cable cards

Hi,
We recently upgraded to Fios Quation 150Mbps/65 plan. We are not getting the advertised speeds (we only get like 5mbps upload) so verizon is sending a tech to switch the ONT connection from coax to ethernet.
I have 2 questions regarding this new setup:
1. If the ONT communicates with the Fios Actiontect router via ethernet instead of coax from now on, How will the set top boxes and Tivo-esque cable card powered device I currently have connected to coax, talk to the verizon system from now on, if coax is taken out of the equation? Will fios signal still flow through the internal coax wiring of the house? And moreover, I was under the impression that coax was the way set top boxes communicated and derived independent ip addresses from the Fios router, for on deman purposes and what not. How will this work from now on?
Quiestion 2.
Right next to the wall where the ONT sits, theres's a basement office where we have a PC that connects to the Fios system via an Actiontect MoCa adapter (ECB2500C) which I assume derives it internet connection from the Fios Actiontec router which sits upstairs in the living room.
Again, with the Coax about to be disabled next Friday in favor of ethernet connection from the ONT, I assume this PC will be left without internet because of the lack of internet signal in the coax? Is this correct?
Question 2.5 If my above assumption is correct, since this office is right on the other side of the wall where the ONT sits outside the house, would it be possible to run an ethernet wire through the wall that connects straight from the ONT to an ethernet switch inside the office, from which I would derive a connection for this basement PC (properly firewalled of course) and then, from said switch, continue running the ethernet wire that would ultimately reach the Actiontec Fios router upstairs from which the rest of the house derives it's internet? and would this setup affect in any way the propper functioning of the cable boxes in the house?
I'd appreciate your input and any help you can provide so I can have a ballpark idea of what to tell the Fios guy to do when he comes on Friday.
Cheers.
Solved!
Go to Solution.

It's not valid to have two devices connected to the ONT, PC and VZ Router. Must be a single device. The ONT locks onto the MAC Address of the first device it sees. Since you have TV you should have the VZ router as the internet facing router.
Other options:
1. Have the VZ Router located next to the PC in the basement and then use Wireless for all other PC's.
2. Have the VZ Router located next to the PC in the basement but run one wire upstairs and connect a switch where other PCs and devices can connect via a wire.
Hope that helps.

Connecting via USB and FireWire at the same time...

Hey all,
I have a 3rd Generation iPod (with the play/pause, menu, next track and previous track buttons between the screen and the touch wheel), and I just bought a new Nano.
Obviously, I want to keep them both synced with my MBP, but there's a problem. The 3G will sync via the Dock-to-USB cable, but it will only charge and sync with Dock-to-FireWire. The Nano, on the other hand, doesn't support FireWire.
So, in order to sync/charge them both, I have to use a different cable for each.
Or, do I? Apple sells a Dock-to-USB-AND-FireWire cable (one Dock Connector with two wires coming out). I'd love to plug both the USB and FireWire connectors to the MBP and then just plug the Dock connector into one iPod and then into the other. But, in the documentation for the cable, it says not to connect both the FireWire and USB ends to the computer at the same time, or it might result in "unexpected behavior."
Does anybody out there have any experience using this cable with both ends connected at the same time? Does it work? Have you noticed any "unexpected behavior?"
I wanted to check before I go defying Apple's instructions.
Thanks,

Can I share my internet connection via wifi AND use my wireless printer at the same time?

Not completely familiar with wifi capabilities. I have this new setup in my office. I want to share my iMac internet connection via wifi so I can text and check emails using my iPhone (no cell service inside the building). Which works fine. However, I now cannot print wirelessly to my HP printer (LaserJet Pro 400 color). Once Internet sharing is off, I can print just fine. Any other wireless options, or just go get a long USB cable?

Hi,
It is not a multitasking printer, other devices may keep it therefore the best option in this case: connect it to your wireless router and all devices which are conntected to this router can sahre the printer.
Regards.

Questions on Firewire cable connection

I usually disconnect my Alesis Firewire audio interface by unplugging the firewire cable from the back of my iMac. Is it okay to just unplug it from the interface, leaving the cable connected only to the back of the computer?
Also, if I want to run all audio thru the interface is it okay to leave it connected all the time? (It's powered only by the firewire connection but does have it's own power available).
P O'Flynn

Hi poflynn
Yes it should work fine to leave the cable connected to the iMac and just plug and unplug the Audio Interface. Although if you had a FireWire or Combo USB/FireWire Hub you would save ware n tare on the Audio Interface's connection, by just plugging and unplugging it's cable from the hub.

Unable to set wireless connection with imac and Canon MX860 printer ...

I recently converted to a Mac and bought a Mac Book, iMac, Airport Extreme, and a Canon MX860 printer. i have installed the canon software numerous times on my iMac to set up the wireless connection. yes, the airport extreme recognizes the printer and i am able to connect to my private and guest networks. the signal strength is good. It's the next part that I'm always stuck at. The Printer settings does not display when i choose More Printers and select Canon IJ Network. I called Apple support and we tried changing my network settings to an unsecured network and it still has the same issue. It was recommended this may be Canon driver issue and advised me to contact Canon. I reset the Airport, changed my network name and password .. i think i tried everything and it still does not work. What was I thinking when i said i wanted to convert to Mac? I can't move forward and connect my macbook or pc yet until I successfully connect the imac. Yes, i installed the latest canon IJ Network tool. of course the USB connection is fine but that defeats the whole purpose if why i bought this printer. please advise how to fix. this is getting very frustrating.

Some help at http://store.apple.com/us/product/TV352LL/A perhaps in the comments.
And maybe at http://www.amazon.com/Canon-PIXMA-MX860-Wireless-Printer/product-reviews/B001R4C 5BK in the comments.
"I ran into the same network installation issue that I've seen in other Canon printers. Canon's network setup forces you to connect by USB cable first. Only after you tell the program that you want to use the computer over the network can you remove the USB cable, move the printer if needed, and if you're using a wired connection, reconnect a network cable. The process isn't particularly difficult, but it's more cumbersome than what other printers let you do, which is simply put the printer where you want it, plug in an Ethernet cable, and install the software." source = http://shop.pcmag.com/shop/product/pcmag/84634068.aspx?SB=6&OB=1
"MAC wireless network printer setup requires turning off firewall, and works fine if you leave firewall off (not recommended). If you set firewall at "essential connections only," wireless networked MX860 won't work. You must add MP navigator and solution apps to your firewall enabled list. Then it worked fine on the admin account, but still won't work on users account which required additional permission settings and selections. After 2 hours it worked fine, but I would've expected better instruction manual for MAC." source = http://cnet.nytimes.com/multifunction-devices/canon-pixma-mx860/4852-3181_7-3352 9769.html
"The only trouble that I have had with this machine is setting up the wireless network. The manual instructions are impossible for me to understand and I ended up having to call for assistance. Which easily solved the problem. And again when I had to reconfigure my network settings it was impossible to follow the logarithm of instructions in the manual. Again I needed to call for assistance. If I need help after the year manufacture's warranty I will be charged for these calls." source = http://www.zimbio.com/InkjetPrinter+Reviews/articles/1932/Canon+PIXMA+MX860+Wireless+One+PhotoPrinter
Even Windows people have trouble:
"I NEED INTRUCTIONS ON HOW TO CONNECT MY HP LAPTOP TO THE CANON MX860 PRINTER."
"I'm with you. I have my mx860 connected usb to my pc with the printer being shared but my wireless laptop can't find it no matter what I try."
And, unhappy Vista person:
"I had high hopes for this printer - it seemed to have it all. But the wireless feature never worked, it only worked on my gigabit network for about two weeks (only THREE print jobs including the test print), and never observed it to work via USB - Vista (x64 Ultimate) would throw an error saying it could not attach the device."

Printer and Network connection between imac and PC (Wireless)

Hi All
I Have connected successfully to the internet via my imac through airport as has my pc through a wireless network card. But my problem is sharing files, networking between the two computers, it doesn't want to happen!!
And i am unable to print through the imac, the printer is linked up to the PC via a USB. The imac and PC are both connected to a wireless router/modem.
Would like some advise on these issues. Any suggestions welcome!
Cheers.

Everything I know about a mixed Mac/PC network, I learned from iFelix and Joel Shoemaker. They both have fabulous sites that go through the process step-by-painful-step.
As far as the printer sharing goes, it took me a while to get it right, but I ended up using both the files found here and got it to work. Of course it was an HP printer, but there are others located here for other brand printers.
Good luck and let us know how things turn out.

MB Air cannot see TC 1T '09 while connected via WiFi and Ethernet.

I have a TC 1T 2009 7.4.1 that I have set up successfully with MB Pro and MB White. However I cannot set it up with MB Air v.1 which is connected to TC via WiFi AND Ethernet cable. Internet is fine (Safari) but no TM - when I run APU 5.4.1 it cannot discover the TC it is connected to.
I tried connecting after hard-reset (poke/power on), it would see the TM but then hang forever reading the configuration. So I set it up with MB Pro and MB White and both are now working fine with TC/TM. Then I tried MB Air and it failed.
The TC is connected via ethernet to Sagem router (bridged mode) which supplies WAN and DHCP, it has its own WiFi as well.

And by the way, Hi Everyone, how rude of me not to greet you in the post.
Thanks for any help!

Connecting My iMac and Macbook

I am currently trying to connect my macbook and iMac to share files between them both. I have file sharing enabled on both computers but when i go to the finder and see my macbook under the shared pulldown menu it wont let me connect. It just says Connection Failed and nothing happens when i click Connect as. This happens when i do it from my iMac and my Macbook.
I am new to this so any info would be greatly appreciated.

Glad to hear it's fixed! When you do an 'archive' install, all the directories associated with the OS are moved to a "Previous System" -- this includes folders you don't normally ever store your own files or applications in, as well as the applications & utilities that would have originally come with OS X found in the Applications or Utilities folder (which are replaced with fresh copies). This folder exists for archive/reference purposes only. OS X will never actually use anything in that folder ever again.
You can see a detailed list in this article: http://support.apple.com/kb/HT1710
Anything YOU put on the Mac (apps you installed, files in your home directory, etc.) are mostly not affected.
I say "mostly" because there are a few exceptions and these wont apply to everyone.
Any app you install which has to modify an OS component in order to work (the most common example I can think of is a 3rd party VPN -- for example I use Cisco VPN on my laptop.) While I would still see the Cisco VPN icon in my Applications folder, if I were try to use it, I would find that it doesn't actually work. The solution is to remove the old app and re-install it again.
You'll find the "Previous System" folder is taking quite a chunk of disk space. It doesn't hurt anything to leave it, and the only reason to leave it is if there were any files you modified that you might want to reference (for example... if you added static host definitions to /etc/hosts and wanted to copy these entries to your new /etc/hosts) -- again... things that most users would never touch.
Once you've been using your re-installed Mac for a while, have exercised every app you've installed (at least once) and find that everything is working, you can go ahead and free up that disk space by erasing the "Previous System" folder.

Connecting 2 iMacs and using Syncopation

For some reasen I just don't get it done: connecting two iMacs (with up to date software) and then using Syncopation 2.2 to make a back-up of my iTunes library.
I'm not comfortable with 'networks' and this seems to play a role here.
I have connected the two Macs using ethernet but I have the feeling I forget something or do something wrong.
That, combined with the fact Syncopation provides very unsatisfactory instructions, makes that although the machines 'see' each other:
a newly bought album is not back upped to the second Mac.
If anyone can provide me with a step-by-step-manual-for-complete-dummies to solve this, I would be very, very grateful.
Thanks!!!

We do not have any way to know how your app 'Syncopation" should work or is working. You need to go on the web and contact Syncopation's web Techincal Support to get proper help with that.
