IMac :: Firewire Device Only Capable Of 400 Mb/sec Speed?
Feb 10, 2009
in my system profiler under firewire it says : -
FireWire Bus:
Maximum Speed:Up to 400 Mb/sec
Does this mean that an external hard drive with firewire 800 will be no good to me? Or does mean that the last firewire device was only capable of 400 mb/sec?
I've been looking at a number of different Firewire 800 enclosures to use with my new Mac Mini and I have seen lots of complaints with almost all the enclosures that I have investigated, including the Newertech MiniStack v3 which I thought should be a good one. A recent enclosure I came across that I haven't seen any bad reviews about is the Icy Dock (MB559UEB-1S). I'd like to know if others are using this and what they think about it. The next question has to do with the type of hard drive to put into the enclosure. Is it worth getting a high performance drive, or will the Firewire 800 interface be the bottleneck even with an average speed drive?
I've attached my external drive to my 17 inch macbook Pro, on the wirewire 400 port, and it shows up under the profiler as as "Unknown device". The same drive looks fine on my iMAC OS version on both machines is 10.5.2. If I use the USB2.0 port on the drive and connect it to either machine it can be seen by both.
I recently had to take my mac mini to pieces to upgrade its RAM to 2GB. I initially had problems with booting up - it would get to the white screen with the apple logo and think for about 2 minutes then restart and repeat the process indefinitely. I managed to fix this by removing the clock battery for a while. I also zapped the PRAM after installing. But now, the strange problem is that OS X wont boot up (it will get to the white screen, think, then restart) if my firewire devices are connected. In case this helps, I have two HDDs and a DVD burner connected in daisychain to the firewire port. It definitely boots up fine with any other peripherals/connections. Once OS X has booted successfully, I can then connect my Firewire devices which seem to work fine.
I have tested my new RAM with memtest and rember and everything seems fine. After upgrading my RAM, I would also get two alerts on start up - "Do you want the application "configd" to accept incoming network connections" and "Do you want the application "mdnsresponder" to accept incoming network connections ". I have fixed this problem with the help of this post: [URL]. Aside from the horrible idea that I have damaged some hardware, does anyone have any clues as to how I can mend this? A wise colleague of mine said that if it was a windows machine, he would look at the BIOS settings as he thinks my computer is trying to boot from one of the HDDs, and that I should try to find a list of boot drives and remove the firewire HDDs if they're on it. I know macs don't run BIOS, but is there anything similar I could check?
I'm attempting to upgrade a family member 800mhz iBook G3 from 10.2 to 10.4 using my old iPod as the install drive. (Restored a DMG, etc) Only problem is that (other than being an ancient computer, I guess) is that said iBook doesn't see the iPod until after OSX loads (white spinny guy).
Tried holding Alt at bootup (not listed), setting it as the default boot device (just skips it and goes right to the HD), and just running it from OSX (reboots, straight back to OSX desktop).
Is there something I'm missing? Does this model G3 not allow detecting boot devices at start up? I'm kind of at a brick wall here. Should I just bite the bullet and do a target disk install?
I have an old 828 audio interface I've been using for years on my pc. just switched to mac with dual intel macmini running os x 10.4
I went to MOTU's website and downloaded os x drivers, and installed them... but I still can't get the computer to see the device. Profile or whatever shows the firewire ... yet device doesn't show up
Is there nothing like scan for devices on that port I can do in os x?
I'm wanting to connect my DV Camera and an External Firewire HDD to my mini. I really only need two firewire ports: one for the camera and one to daisychain any further Firewire HDD. This is all in aid of being able to digitize HD Tape footage with the mini using FCP so I can do all the editing etc of the Mac Pro. I've found a few online such as:The Belkin Firewire 6 Port Hub, Belkin Hi-Speed USB 2.0 and Firewire 6 Port Hub and the 1Lynx 800 Advanced Firewire Hub (99MO018202).The stackable Belkins look great
'08 Mac pro kernal panics every time i turn on my firewire recording interface, an echo audiofire 12. the strange thing is, it runs fine if i turn the interface on before booting the computer.
Windows 7 has been awesome so far, but there are still the occasional driver issues. What I'm having trouble with now is firewire. I used to use HFS Explorer to access my external (HFS formatted) hard drive but it no longer shows up in HFS Explorer. Windows doesn't even make the "device connected" sound when I turn it on (yes I'm running HFS Explorer in admin mode/Vista compatibility). Pretty sure it's a firewire driver issue, but I have no clue who makes the firewire for my early 08 MBP.
Yesterday I took delivery of the following kit- http://www.dolphinmusic.co.uk/produc...firewire-.html
As you can see, it comes with the FCA202 Audio interface - http://www.dolphinmusic.co.uk/produc...io-fca202.html
I opted for the FireWire package as it has the most better quality mics. I got it all hooked up, but for some reason, my Mac is not recognising my new sound device at all. I was looking under the Sound part of the Control Panel, but nothing new would register. I checked the FireWire part of the Device Manager (appologies I forget the actual name of the application). The Firewire device was listed as "Unknown", if I was to remove the device and refresh, it would show nothing. So i've got the feeling that its been seen, just not recognised correctly.
I tried a few things to try and help my situation.
1) Disconnecting any other attached device 2) Rebooting several times 3) Leaving system off and unplugged for 10-15 mins 4) Updating all software 5) Resetting my xxxx (I forget the term, but it involved rebooting holding CMD, Option, R and P) - can someone confirm how I know if this was actually reset? 6) Going into Activity Manager and confirming the Audio driver is loaded
From what I've read, Firewire config issues can be common with Macs. I am running an 18 month olf iMac 20" with 4 gig ram. I've not used my FireWire port for a while, about 6 months ago I used a FW external HD which didn't have any problems with. Alas I don't have any other FW devices to plug in and test the port. The final thing I'm going for is to leave the system unplugged for 10 hours, which will be ready to check after work.
One thing I was thinking about though - would getting a powered FW hub be of use at all?
One day I couldnt wake my macbook from sleep with my firewire WD Mybook 500G connected, so I power off the macbook manually and start it up again. It then triggered kernel panic, and i found that my macbook resume normal if i do not connect the firewire external HD. I performed PRAM reset and even PMU reset but it still couldnt help.

I have a Mackbook pro and I need to set the firewire speed to use a camera which works with 400 Mhz, in my mackbp the system info sayd 800Mhz.How can I change the firewire speed?
I just got a Mac Mini (March 2009 model) and want to connect it via Firewire to my Sony TRV-22 camcoder. The camcorder has a Mini DV Firewire jack on it (I think this is called a 4-pin connector sometimes too). But on the Mac Mini, I can't tell if I need a 6-pin or a 9-pin. Can someone point me to a good cable so I can dump some MiniDV tapes into iMovie?
I Have an Imac that is a couple of years old (2006 white). Here is the system profiler specs:
Model Name: iMac Model Identifier: iMac4,1 Processor Name: Intel Core Duo Processor Speed: 2 GHz Number Of Processors:1 Total Number Of Cores:2 L2 Cache (per processor):2 MB Memory: 2 GB Bus Speed: 667 MHz Boot ROM Version: IM41.0055.B08 SMC Version: 1.1f5
My daughter just bought Ilife 09, and while I was reading the requirements, it says it requires OSX 10.5 (Leopard). I am running 10.4.11. I would buy Leopard, but I heard it needs a computer with a minimum bus speed of 867 MHz. It seems to be a domino effect. I would buy it, but I cannot return it opened.
My first question is, what will the 4850M GPU be capable of? Say in terms of playing Crysis: Warhead and BFBC2?
My current system is a 08 Mac Pro Octo @ 3.0GHz, 18GB 800MHz RAM, GTX 285, and Intel X25-M G2 SSD, 1920x1200 res on a 23" ACD.
How comparable is the 4850M 512MB to the GTX 285 1GB? Could I play Crysis on medium settings w/ no AA @ 2560x1440?
My second question is, how easily can I install an Intel X25-M G2 SSD? Also will I be able to take the iMac into the store and get them to install the SSD?
My third question is, will I notice much of an improvement over my current system. The iMac has faster RAM, and newer Core i7 processors @ 2.8GHz that turbo up to 3.46GHz.
My fourth question is, when using Parallels 5 Desktop for Mac and configuring a VM I can choose how many processor cores I dedicate to the VM, will it show up as 8 or only 4?
I'm looking to replace my current external drive with a newer, larger drive. My current drive is connected via Firewire and houses my iTunes library, plus movie files, documents, etc. I'm trying to decide between a portable drive (the Western Digital Passport, for example), and another desktop drive (like say, this one [URL:..]Questions I have:
- Is there any reason to be concerned about longevity when using a portable drive? - Does a desktop drive typically perform better than a desktop drive? - Is there a noticeable speed difference between USB 2.0 and Firewire?
can anyone tell me if the built in camera on the new imac is capable of capturing video? can this only be done in ichat? i figured out how to take pictures using photo booth but i figured there must be a way to use this camera as a webcam without video conferencing or chatting. any suggestions?
I'm considering buying an iMac (Which would be my first Mac) soon, and I have a few questions I'd like to have answers to before buying one. I plan buying the new Quad Core 27" iMac, in case it matters when answering my questions.Is it possible/recommended to add non-Apple RAM to the iMac? Are there any disadvantages to this? What are they?Is the new Magic Mouse capable of middle clicking in any way?Is there a wired version of the Magic Mouse? I'm not a big fan on Wireless keyboards and mouses, as they run on batteries.I've read somewhere that to right click in Magic Mouse you have to raise your left click finger, is that true? It may seem like it is according to the video in Apple's website. (The demonstrator raises his finger before he right clicks.)
I have always liked the iMac G4 since i was a little kid and thought that the computer in the commercial looked cool. I wanted to get one for my birthday but my dad thinks that since it is like 5 years old it would not be capable of performing the tasks i do every day, like watching videos and listening to music on iTunes, watching YouTube videos, going on facebook; twitter; and other Adobe Flash and Java based websites. Does anybody who owns a mac know if it plays videos well, if it supports modern Adobe and Java players, and if it is generally a fast computer?
I am interested in adding a webcam to my desktop Imac (power pc)- Isight is no longer available- an option that I found is the Ecamm Image- but apparently it is USB and not firewire and it will only run with high speed usb- how do I know which type is on my computer? I checked system profiler but quite frankly wasn't sure of the designations.. does anyone have any experience with this camera, by the way? is USB 2.0 by definition "High Speed"?
Last night my fan kicked into high gear all of a sudden. I shut it down overnight and when booting up this AM I find it still running on high...quire noisy, of course. Is there something overheating? How to make it run at normal speed?
Does anyone have a clue if it is possible to connect an esata device to an iMac? I've seen usb to esata adapter but are they as fast? Is it worth it compared to firewire 800?I do hd video on my portable hdd, so i need something fast.
I have a Panasonic PV-GS15 camcorder that has usb and Firewire support.
I Current have a 2007 iMac 24" 2.4 with 10.56 installed, and I have been having tons of problems with OSX recognizing the camera.
It seems I need to reboot the machine, turn on the camera and do my importing, but once I turn off the camera and try to use it again later It requires me to unplug reboot and repeat the process each time.
I have had to disable the isight camera in order for it to even get this far.
I have the new iMac 27' and was trying to capture some video from my DVR via a composite cable-USB converter. The composites run into a USB cable. So I plugged the USB cable into my Mac and tried to capture the video. Nothing came up in Toast showing me how to capture or even giving me a option to capture. Anyone know how to capture video using this method?
why that when i try to press hold the 'control' key after on my imac there is still pop out error - no bootable device in a black screen.its look like no connection between my wyerless keyboard and my imac..??help me...im new with apple computer.
