After 10.9.2 upgrade no firewire 800 connection

After upgrading (iMac 24 2007) to 10.9.2 Mavericks the connection to all of my firewire drives got lost.

Hey Guys,
After recent SMC+EFI update on Macbook Air (Mid 2013) OSX v10.9.3, my internal audio device disappeared,
I tried everything I could find in google with no luck. (NPRAM+SMC reset, reloading kents etc.)
THIS IS WHAT SOLVED THE PROBLEM FOR ME:
1. I opened /System/Library/Extensions folder, there I found besides the usual AppleHDA.kext, also an AppleHDA.kext.disabled one.
2. I switched between them (swapped their names, sometimes you'll have to do it from the "get info" menu to take effect)
-- if you don't have this AppleHDA.kext.disabled one, try searching for one lil older than yours in the internet
3. then I unloaded and reloaded the kent dir again-
sudo kextunload /System/Library/Extensions/AppleHDA.kext
sudo kextload /System/Library/Extensions/AppleHDA.kext
And voila!
Hope it helps someone, as I spent hours until getting this to work again

Firewire 800 Connection Dismounting

We've been having major issues with the Firewire 800 port on our recently purchased iMac 27" (with Thunderbolt).
For a while we noticed the Firewire 800 port was rather flakey, dropping connections here and there. It's now almost consistant - as soon as we set up any sort of transfer the transfer begins and after about 1.5 gb or so have been coppied the drives will start spinning strangely and the "Did Not Eject" warning appears.
This is with SEVERAL drives, all of which work fine with the other MacPros/MacBook Pros in the office. These drives are also just fine with USB so it's not the firewire on the drives themselves. It seems to be particualrly bad with any drives which are bus powered.
Tried several different cables and I know thats not the issue either. The problem still persists.
We are a media studio specializing in broadcast and design and this computer is used predominantly for video editing which means we transfer a lot of our large files via Firewire 800, so it not working puts a serious kink in our workflow.
Anyone else noticing the issue with these recent iMac 27" (which I've heard feature a whole host of issues)? Anyone know how I can get in touch directly with Apple?

Canon Gl2 Video Camera Not Recognized with Firewire 800 Connection

I have a late 2010 mac with 2.93 Ghz Intel Core i7 Processor with 12GB DDR3 running 10.8.2 OSX. I have a Canon GL2 video camcorder with a MiniDV tape I am trying to download to my computer. I am using a new 4pin to 9pin Rocketfish Firewire 800 cable. My computer is not recognizing the firewire input from the GL2. As suggested with other support threads, I have tried to turn the mac and computer off and on, as well as check to see if the cable is working. I have also tried both a trial version of Final Cut, and Imovie 09 which is loaded on my Mac, neither of which will recognize the camera. I clicked on the System Information icon and looked at the Firewire 800 status which was:
FireWire Bus:
Warning: Unable to list FireWire devices.
Maximum Speed: Up to 800 Mb/sec
At least I know it recognized something. I have also checked to make sure the Canon is set to DV-Out on the Menu. Since I am unable to use a USB connector with MiniDV, would there be any other way to either A) Download the video to the computer, or B) get the Mac to recognize the source plugged into the Firewire? Any help with this would be excellent.

I believe that in order to be recognized, you have to start the process from within iMovie of Final Cut; as for your FW port, you can try these two different troubleshooting steps (may or may not work, but won't hurt):
Reset SMC:
http://support.apple.com/kb/HT3964
PRAM:
http://support.apple.com/kb/HT1379
It may that your FW port is defective; it that turns out to be the problem, I hope you purchased Applecare because those ports are an integral part of the logic board, so that would have to be replaced ($$$).
Since your footage is on DV tapes, you do need the FW to transfer it or it will not work. One other (involved) way would be to transfer your footage to a DVD if you have a DVD recorder and then get it on the Mac from there.

Securing FireWire 800 connection to Macbook Pro

I am really surprised that there doesn't seen to be one post here related to the poor connection FireWire 800 makes on the Macbook Pro. The portable nature begs for this to stay connected when there is movement. Not so. Judging from this discussion, many others have experienced this problem. It also seems that Apple doesn't want to take any ownership for it judging from Genius bar advice.
Has anyone found a way to fix this issue?

It seems that it all depends on the cable - I use FW800 on my MBP and can wiggle around to my heart's content with the FW cable plugged in. No problems with my cable on a late 2011 MBP.

After 7.0.6 upgrade Icloud email "Cannot Connect To Server". All other email works fine.

After upgrade to 7.0.6 both IPad and iPhone now will not send or receive Icloud email while at home. Get "Cannot connect to server " message. All other email accounts (google, verizon) work fine. Plus the "last backup" information unavailable as well as icloud storage information. Says unavailable, try again later. Also cannot view body of emails sent or received in the last 2 days. I am at work now and all works normally. If this is a wifi issue, I I do not understand why all other email accounts are sending receiving ok. It's only the Icloud server that seems to be the problem.

After 10.9.1 Upgrade, Mail Account Not Connected

Mail accounts (pop) are not staying connected after the upgrade when the Mail app opened.

It seems all is well this morning. So, Mail might not have any issues, and it might have been my company's host was experiencing problems that coincidentally occurred right after I had upgraded to 10.9.1.

Firewire 800 connection down on an Intel iMac - software or hardware of cab

It appears that my Firewire connection from an intel imac 2GHz seems to be down. It is not showing up in the "More information" section in the in "About This Mac". Is this a software or hardware or cable issue?

Have been using FireWire 800 connection for WD MyBook Studio

Have been using firewire800 with my WD MyBook Studio primarily for Time Machine backup. May need to be replaced - if I replace with WD MyBook for Mac or something else ( perhaps Seagate) with usb2.0 will I notice a big change in time for TM? If I transfer files to another ext drive, will I notice longer time saving iTunes or iPhoto to an express drive??
Any comments or suggestions are welcome. I have always used WD but wonder if Seagate or someone else has something.
Thanks

WD electronics in their external drives don't have a very good reputation, so another brand might be a good idea. I like OWC drives as many of them use Oxford chipsets as well as multiple connections like USB and Firewire (I prefer a Firewire connection). Some examples are this or this.
I use a BackPack to get my external drive off the desktop, which is a handy way to mount it.

Firewire 800 connection problem

Hi!
So my warranty just expired a month ago. I went to get my mac fixed right before it and it came back with an issue with my firewire. No big deal really. I called back, they helped me fix it, but now it's doing it again.
The external hard drive I connected to the FW8 port works fine. I've tried it with other cables (FW4 and USB2) so I know it's not the hard drive. However, when I try using the FW8, it does not show up at all. I have 2 different external drives and I've tried both of them. Last time when we fixed this, it turns out my mac was trying to boot from the disk or something? I can't remember... nor do I have any idea where to start to mess with the configuration. Help please? the disk is lighting up, so it is powering on... it just isn't showing up!

I'm completely confused: you start by saying "The external hard drive I connected to the FW8 port works fine." Then in apparently complete contradiction you write:
However, when I try using the FW8, it does not show up at all.
What do you mean, "the disk is lighting up?"
And:
Last time when we fixed this, it turns out my mac was trying to boot from the disk or something?
The Mac should be trying to boot from some disk.
And then:
I've tried it with other cables (FW4 and USB2) so I know it's not the hard drive.
What does that mean? What is it in, "I've tried it....?" And, are you saying it works (which I suppose means the external does mount) using the FW4 and USB Ports?
I know you have a real problem but I really have no idea what you are asking
In case, as your topic suggests, you are simply asking about a problem with the Firewire Port, do what Roger suggested and have a look at this article.

Firewire 800 connection comes lose

i added a ministack max to my 2010 mini and the firewire cable does not stay connected
any ideas to make it stay. i figure it getting nudged when turning off an on is doing it.

I had a similar issue and found I needed to get a different cable that had a slightly longer nose so it would insert deeper into the receptacle. Not all FW cables are the same dimension.

Dropping Firewire 800 connections

I have 3 FW 800 backup drives, and lately whenever I plugin any USB device, all the FW drives are disconnected, with the usual warning that "some drives were not ejected properly..." or similar. I thought it might be the WD MyBook but it happens even when the WD is not in use.

Hi Dan
i too have been noticing this lately and thought it was just me. I have almost the same specs like your 24 and the drives i have hooked up are in the same fashion. Independent electrical USB powered. Guess what i realized (keeping in mind that i am also using 2 drobos 1. FW800 and 2. USB version
* i have a very strange feeling as the discussion went on here, the logic board or the power management for FW800 on the iMac line really really is poor! (i would use other words to describe it)
* Let me walk you through what i did :
- the USB drobo is older and much slower but works fine
- the newer FW drobo has been doggy lately
here is what i tried:
- changing the USB cable
- changing the FW800 cable
- constantly pulling it in and out of the iMac
-Still nothing!
- in my new messy place i happen to glance a nice little cable which is a FW 400 to FW800
- I THINK U KNOW WHERE THIS IS GOING
- I hooked up the FW 400 to the iMac
- FW800 on the drobo
-PRESTO the it works!

No response from Firewire 800 connection.

Hi,
I have two Freecom HardDrive Pro FW400/800drives. One (1TB) is brand new and unformatted. The 512GB drive is connected by FW800. I can see the partitions, but cannot access them. Changing to FW400 gives me full control. When attaching the new drive by FW800, it spins up but cannot be seen.
Can someone help diagnose this one for me please?
Thanks,
Tris.

Time Machine won't mount Firewire 800 drive after restart / Finder crashes

I've been having problems with Finder crashes. I first suspected Spotlight might be the problem because sometimes when I started typing a search, it would display the first 3 characters and then lock up. I could force quit the Finder, but it wouldn't relaunch and required the computer to be shutdown and restarted with the power button. Once restarted, I had no keyboard and no mouse click (the mouse would move across the screen but I could not click on anything). After waiting several minutes (3-5) the mouse and keyboard worked properly.
After some research suggested the Spotlight index might be corrupt, I forced Spotlight to rebuild the index (add the drive to the exclude list under "Privacy" and then remove it from the list) and then repaired disk permissions. After that Spotlight was noticeably snappier and I thought my Finder crashes had been solved until........
Part 2: I have been using Time Machine (connected to a Fantom GreenDrive via Firewire 800) for several months now and ever since the beginning, I have noticed that the drive will NOT mount after a restart. I must turn the drive off and back on again to get it to mount. After that Time Machine picks it up and seems to work fine.....well, that is until this Finder crashing thing started several weeks ago. Anyway, I inadvertently set up an experiment last weekend when I installed some software update and forgot to remount the Time Machine drive after the restart. That was last Sunday night. The computer did not crash all week long. I thought my Spotlight fix had finally solved my problems, but now it seems I was wrong. This morning (Saturday, six days later), I noticed my Time Machine drive was not mounted. I mounted it, told Time Machine to "Back Up Now" and went away for a few hours. When I came back the Finder was locked up.
So guess my question is this: Are there any know problems with using Firewire 800 with Time Machine? and What can I do to fix this? In the meantime I'm trying another experiment - I've disconnect the Firewire 800 connection and replaced it with USB.

Hi, and welcome to the forums.
Not in general. Some drives don't always wake or "spin up" fast enough; often that's seen when the system wakes from sleep, though, not so much after a system Restart. Many Western Digitals do that; I don't recall seeing any posts here about yours, but you might want to search the forums for Fantom
In the meantime I'm trying another experiment - I've disconnect the Firewire 800 connection and replaced it with USB.
Good plan - that may provide a clue.
Also, check with the maker -- there may be a firmware or driver update.
And try verifying your internal HD, and repairing your backups, per #A5 of Time Machine - Troubleshooting (or use the link in *User Tips* at the top of this forum). Either might cause that.

LaCie 250gb invisible when using Firewire 800

My LaCie 250gb which I use as an external backup is not recognized by my computer when I use the Firewire 800 connection. What could be the problem?

Damian,
Following are my experiences. My setup is listed down below.
-Yes, that will fix the problem. The bottom line is, M-audio FW box doesn´t like to share disk drives on the G5 firewire bus (both 400 aand 800). So yes, 400 and 800 FW ports are somehow connected internally, sharing the same resources.
-I had a spare FW 400 PCI card lying around, and I attached my disk drives to that. Didn´t start to look around for a FW 800 card though.
-And although it seems like a fault on Apple´s side too, I can´t speak very highly on the FW410 box either. Every time I do an update on my system, the 410 install gets messed up (won´t show devices in AudioMidiSetup, the only cure is to uninstall and re-install).
And the other interesting thing is that every time my Mac boots up, the 410 control panel mixer page is all messed up with funny pan positions and fader values. A reset does the job, but this has to be done every time I boot up. Maybe this is working in Tiger.
I tried solving this with the M-Audio support, and after describing my problem, they just said I should call their tech support. Being on the other side of the world, I shurely don´t wanna max out my phone bill.
Haven´t upgraded to Tiger yet, don´t want to keep upgrading all the time. In general the system is working nicely.

New Firewire 800 External Hard Drive and how to use old External USB Drive

Hi All,
I have a new LaCie d2 Quadra Hard Disk hard drive 500 GB - FireWire / FireWire 800 / Hi-Speed USB / eSATA-300 on the way, when it arrives I plan to use it as my Time Machine Backup drive with the FireWire 800 connection. I am currently using a Seagate Free Agent USB 2.0 320 GB external drive as my Time Machine disk. The reason for upgrading is the USB drive is slow slow slow! I am not concerned about the data on my old drive and will just wipe it clean using Disk Utility. What I would like to do is use the old drive to archive iTunes 7.7.1 and Aperture 2.0 music and photographs. Can someone give me an idea how to go about doing this?
Thanks!

Hi, yes that will copy the whole iTunes..including everything in iTunes..BUT, as you add to your iTunes on the Main HD, with the ext HD I think you will have to manually update anything added. Or dragNdrop the whole thing again.. You could also locate you iTunes music Library & just copy that across..With images once again find your iPhoto library & just copy that across..L
