IMac And Firewire Solo - Power Problem

Hi!
I got an iMac and a M-audio Firewire Solo audio interface. I wanted this interface to be powered by the current adaptor and NOT by the iMac.
M-audio says that if I plug it with a 6pin cable the computer will power the interface (not using the adaptor). So Can I avoid iMac to power the interface? I mean by stopping the firewire power or something..
thanks!!!

The easiest way would probably be to put a pair of 6 pin to 4 pin adaptors (of opposite "genders") into the cable run, or to use a 6 pin to 4 pin cable with a single 4 to 6 pin adaptor on the end of it, vivajam. THis should cut the power supply from the Mac to the device.

Cheers

I downloaded OS X Lion on my iMac and I'm having problems with my computer waking up after hibernating. I can get to the login screen but my mouse will be frozen. The only fix's is a hard reboot. Any help would be great!

Try resetting the SMC and the PRAM.
1. SMC
Read this and follow the instructions for your kind of mac:
http://support.apple.com/kb/HT3964
2. PRAM
Follow the procedure below:
1. Power down the machine.
2. Locate the following keys on your keyboard in preparation for Step 4:
command–option–P–R
3. Press the ‘power on’ button.
4. Immediately – and before the grey screen appears – hold down ‘command-option-P-R’ all together.
5. Keep them held down until you’ve heard the start-up chime twice. After you release them you should hear it again, and hopefully your Mac will boot up as it should normally.

My wireless keyboard no longer connects with my iMac since changing the batteries. It now shows as not connected, not paired and not configured. A friend recently connected his iPad to the iMac and since then the problem started. Any ideas to resolve this

a friend told me that he wants my os x cd for my macbook pro to upgrade his imac.
The discs that come with your Mac are "machine specfic" and cannot be used on another Mac.

I have an Itel based iMac on which I created a Wifi network using Airport. My iPhone5 uses the Wifi on my iMac and still works.My problem is that I can't remember the Wifi password and it is not in my Keychain.

Read the router's user manual on how to change your password.
If you are going to select another password, make sure it's one that you will NEVER forget AND no one else can figure it out. Print it out & keep in a safe place. A place that ONLY you know about AND never forget.

M-Audio Firewire Solo+Leopard = problems?

After 6 months of a battling with my iMac, different systems and different drivers. The final replay from M-Audio is this:
This is a known issue with all FW800 Macs (apart from the 1st two G4 tower
systems) when using firewire audio or video devices as Apple has placed the
FW800 and FW400 connections on the same fierwire bus.
In order to run these together you would need to add a PCI, PCMCIA or
Expresscard interface depending on your Mac which will add an extra firewire
bus and allow these devices to function well together.

The problem I get is that every time I tried to use my M-Audio Firewire Solo, the screen goes grey and the power logo comes in the middle with a message asking to switch off the computer from the power bottom
And at that is the only thing to do because is completely frizzed at this time.
I got me a Protools MP to run it with the sound card.I was so happy then, but here I am still wondering.
I have as well an iBook G4 that i had used with Panther and M-Audio FW Solo, and all was fine then. When I upgraded the system to Tiger, is when all the problems started. Now with Leopard it will do the same as in the iMac, won't have it.
Does anyone have the same problem or a little bit of advice?
Thank you
Thank you

hey, firstly, your not the only one going through this, since the last 10.4.10 update, heaps of us musicians have notice fatal errors with the update, mainly, the mac not recognising our devices that were once working fine, but now with the update that are not being recognised by the mac.. check out the other threads and make a complaint to apple:

High pitch whine and FireWire bus power

Delighted with my MBP!
Just noticed the high pitch whine today when I set it up in a quieter room and plugged it into an IOGear bus-powered FireWire hub shared with my other Mac.
It was around 8000 hz and loud enough that I could not stand to stay in the room with it.
When I unplugged it from the hub and connected the cable directly to the FW port, the whine was greatly attenuated (I could hear it only by putting my ear next to the vents at the top of the keyboard).
Could the problem be related to powering the FireWire bus? (It reminds me of the sound of a switching power supply or DC-DC converter) Has anyone else had any success in finding ways to attenuate this high pitch tone?
MacBookPro Mac OS X (10.4.5) 7200 rpm

Hi, Thanks for the suggestion. I'm really trying to cut down on the number of devices that I leave plugged into the mains, so would ideally like a solution that relies purely on power supplied by the internal bus.
I've had a bit of progress with my current set-up. I've switched to using a 2 headed USB lead that came with my Hard Drive. This does mean I effectively lose a USB socket, but it appears that the Hard Drive + the Webcam can now live happily together.
It just means that I have to swap the 4th USB port for whatever ad-hoc device I need to use at the time rather than leaving things connected to it.
Out of geeky curiosity, I'd still be interested to know whether the USB and Firewire buses share their power or each have a dedicated amount.
Cheers,
Ian

OS X 10.7.3 WiFi Update for iMacs and Wake from Sleep Problem

http://support.apple.com/kb/DL1501
Apple has released a software update for those suffering from the iMac wake from sleep/wifi connection issue that resulted from updating to 10.7.3. It fixes the problem for me and several others. For those still suffering this issue, download it and see how it works!

To answer my own question it seems a workaround is to wake the iMac up using the power button rather than the keyboard. The WiFi reconnects this way.

New aluminum iMac and firewire drive

My school recently placed an order for a lab of iMacs and found out yesterday that we will be getting the new model (20 inch).
We had been using old G4 towers with Final Cut Express and external firewire 400 drives.
Since the new iMac will only have a single firewire 400 port can anyone suggest our best options for capture/playback via firewire 400 and also using our existing firewire 400/USB 2.0 external drives? Is there a firewire 800 to 400 adapter that will allow us to use the faster port as a second 400 port?
Thanks for any suggestions you may have.

I think the adapter for converting FW800 to FW400 is the best option in your case. In my case, my iBook only has one FW400 port and I opted for a Belkin FW Hub to allow capture from my camera to my FW400 external HD. I've heard this is not ideal, but it works for me. Would love to get a new iMac one day.
I believe the reason FW hubs are not recommended is because you can end up splitting the bandwidth. Essentially you might end up with FW200 if two FW400 devices are hooked up to the hub. Anybody else know?

Editing Canon 5D to ProRes on an iMac and firewire 800 drive

The Canon 5D footage that has been sent through Compressor to ProRes will not play with any smoothness in FCP 6. I'm wondering if it's because of the Drobo firewire 800 drive? I'm working in a local company's setup and I'm thinking they should be using more than a firewire drive. This iMac is not capable of eSata connection or higher. Any ideas what other cause there could be for the footage playing slowly or freezing all together in the timeline? Thanks.
This is a 2.66 intel core duo iMac with 10.5.8 4GB Ram

When you say, "small portable raids", do you mean like a CalDigitVR or a G-Raid mini or G-Speed?
If you want a drive you can drag around with you, I can't recommend the Caldigit VR Mini highly enough. It is really solidly built and is powered from either the FW bus or an external supply. I used one recently to capture 14 hours of DVCProHD live over 2 days (direct feed from an HVX-200 to FCP on a MBP with the drive powered via firewire) without a hiccup. VERY impressive.
My only quibble with it is there is no independent power switch. When you plug it in (fw or external power), it starts up. Other than that, no issues. The Caldigit RAID software allows for a variety of configurations.

IMac and Firewire external HD not waking up

Hi,
Is there anyone here have an idea why an external HD (Seagate 200GB) plugged into a FW port stop responding after the computer went to sleep?
Finder stops responding and I see the color pinwheel, can't access "Macintosh HD". When I turn off the HD's power, the system's able to recover.
The HD enclosure has 2 FW ports and 1 USB port. It works well when I plug the HD onto the USB port.
I don't seem to notice this behavior on the old G4 PB that I had.
Thanks.

I have a similar problem. Whenever my Firewire HD is plugged in, my computer takes a long time to wake up, and a very long time to turn on.
What's worse: if my FW HD is plugged in and my computer goes to sleep, it kills my Wireless. Not in a fun manner either. To restore, I have to:
Shut down comptuper
Reboot with FW HD unplugged
Not too happy with this. I haven't tried USB yet, but I guess that's a pretty easy answer.

Best connection between new iMac and firewire MacBook Pro

Hi I'm running a MBP with Firewire, USB (2?) and Ethernet ports. I am soon to take delivery of my shiny new iMac with Thunderbolt, USB 3 and Ethernet ports. What please would be the fastest connection I can establish between the two machines? Thanks, M

Ethernet is your fastest choice - FW800, to be precise.
To transfer from the MBP to the iMac use Target Disk Mode. Boot the MBP into TDM, boot the iMac normally and preferably for the first time. This will put you into the Setup Assistant and let you migrate data from the MBP - Home folder, third-party applications with support files, and system preferences.
If you prefer not to do a migration then you can also simply transfer selected items using drag and drop.
A Basic Guide for Migrating to Intel-Macs
The Knowledgebase article Intel-based Mac: Some migrated applications may need to be updated refers to methods of dealing with migrating from PowerPC chips to Intel with the Migration Assistant safely. The authors of this tip have not had a chance to verify this works in all instances, or that it avoids the 10.6.1 and earlier Guest Account bug that caused account information to get deleted upon use of the Migration/Setup Assistant. However, a well backed up source that includes at least two backups of all the data that are not connected to your machine will help you avoid potential issues, should they arise. In event it does not work, follow the steps below.
If you are migrating a PowerPC system (G3, G4, or G5) to an Intel-Mac be careful what you migrate. Keep in mind that some items that may get transferred will not work on Intel machines and may end up causing your computer's operating system to malfunction.
Rosetta supports "software that runs on the PowerPC G3, G4, or G5 processor that are built for Mac OS X". This excludes the items that are not universal binaries or simply will not work in Rosetta:
1. Classic Environment, and subsequently any Mac OS 9 or earlier applications
2. Screensavers written for the PowerPC System Preference add-ons
3. All Unsanity Haxies Browser and other plug-ins
4. Contextual Menu Items
5. Applications which specifically require the PowerPC G5 Kernel extensions
6. Java applications with JNI (PowerPC) libraries
See also What Can Be Translated by Rosetta.
In addition to the above you could also have problems with migrated cache files and/or cache files containing code that is incompatible.
If you migrate a user folder that contains any of these items, you may find that your Intel-Mac is malfunctioning. It would be wise to take care when migrating your systems from a PowerPC platform to an Intel-Mac platform to assure that you do not migrate these incompatible items.
If you have problems with applications not working, then completely uninstall said application and reinstall it from scratch. Take great care with Java applications and Java-based Peer-to-Peer applications. Many Java apps will not work on Intel-Macs as they are currently compiled. As of this time Limewire, Cabos, and Acquisition are available as universal binaries. Do not install browser plug-ins such as Flash or Shockwave from downloaded installers unless they are universal binaries. The version of OS X installed on your Intel-Mac comes with special compatible versions of Flash and Shockwave plug-ins for use with your browser.
The same problem will exist for any hardware drivers such as mouse software unless the drivers have been compiled as universal binaries. For third-party mice the current choices are USB Overdrive or SteerMouse. Contact the developer or manufacturer of your third-party mouse software to find out when a universal binary version will be available.
Also be careful with some backup utilities and third-party disk repair utilities. Disk Warrior, TechTool Pro , SuperDuper , and Drive Genius work properly on Intel-Macs with Leopard. The same caution may apply to the many "maintenance" utilities that have not yet been converted to universal binaries. Leopard Cache Cleaner, Onyx, TinkerTool System, and Cocktail are now compatible with Leopard.
Before migrating or installing software on your Intel-Mac check MacFixit's Rosetta Compatibility Index.
Additional links that will be helpful to new Intel-Mac users:

2. Apple Guide to Universal Applications
3. MacInTouch List of Compatible Universal Binaries
4. MacInTouch List of Rosetta Compatible Applications
5. MacUpdate List of Intel-Compatible Software
6. Transferring data with Setup Assistant - Migration Assistant FAQ
7. OS X Lion: How to use Migration Assistant to transfer files from another Mac
Because Migration Assistant isn't the ideal way to migrate from PowerPC to Intel Macs, using Target Disk Mode, copying the critical contents to CD and DVD, an external hard drive, or networking will work better when moving from PowerPC to Intel Macs. The initial section below discusses Target Disk Mode. It is then followed by a section which discusses networking with Macs that lack Firewire.
If both computers support the use of Firewire then you can use the following instructions:
1. Repair the hard drive and permissions using Disk Utility.
2. Backup your data. This is vitally important in case you make a mistake
      or there's some other problem.
3. Connect a Firewire cable between your old Mac and your new Intel Mac.
4. Startup your old Mac in Transferring files between two computers using FireWire.
5. Startup your new Mac for the first time, go through the setup and
       registration screens, but do NOT migrate data over. Get to your
       desktop on the new Mac without migrating any new data over.
If you are not able to use a Firewire connection (for example you have a Late 2008 MacBook that only supports USB:)
1. Set up a local home network: Creating a small Ethernet Network.
2. If you have a MacBook Air or Late 2008 MacBook see the following:
a. MacBook (13-inch, Aluminum, Late 2008) and MacBook Pro (15-inch,
      Late 2008) - What to do if migration is unsuccessful;
b. MacBook Air - Migration Tips and Tricks;
c. MacBook Air - Remote Disc, Migration, or Remote Install Mac OS X and
      wireless 802.11n networks.
Copy the following items from your old Mac to the new Mac:
In your /Home/ folder: Documents, Movies, Music, Pictures, and Sites folders.
In your /Home/Library/ folder:
/Home/Library/Application Support/AddressBook (copy the whole folder) /Home/Library/Application Support/iCal (copy the whole folder)
Also in /Home/Library/Application Support (copy whatever else you need including folders for any third-party applications)
/Home/Library/Keychains (copy the whole folder) /Home/Library/Mail (copy the whole folder) /Home/Library/Preferences/ (copy the whole folder) /Home /Library/Calendars (copy the whole folder) /Home /Library/iTunes (copy the whole folder) /Home /Library/Safari (copy the whole folder)
If you want cookies:
/Home/Library/Cookies/Cookies.plist /Home/Library/Application Support/WebFoundation/HTTPCookies.plist
For Entourage users:
Entourage is in /Home/Documents/Microsoft User Data Also in /Home/Library/Preferences/Microsoft.
Credit goes to Macjack for this information.
If you need to transfer data for other applications please ask the vendor or ask in the Discussions where specific applications store their data.
5. Once you have transferred what you need restart the new Mac and test to make sure the contents are there for each of the applications.

DVD DL fail to burn AND Firewire 400/800 problems

I have had several months of intermittent DVD burn fails. Most recently today burning from the finder and it is now reporting "The disc can’t be burned because because communication between the computer and the disc drive failed (error code 0x80020022)."
That error is new, previously it was always
Sense Key - Hardware Error
Sense Code - 0x03
The first time this cropped up was on 10.5.x and when I reported it to apple they had me take it to get the drive replaced since it was still covered by applecare.
After the DVD replacement and while still in the shop it burned a few DVD DLs ok. A few weeks later the same 0x03 errors. (it always burns CDs just fine)
After another phone conversation with applecare, they now suggest that the logic board needs to be replaced. (This was after I mentioned I frequently have problems with Firewire 400 or 800 external drives showing up...sometimes they work sometimes they don't. The same drives always show up when connected via USB)
I was walked through resetting the PRAM, which cleared up the Firewire 400/800 temporarily, but it did not help the DVD burn problem.
So on the eve before the appointment, this crazy MBP (2,2, 2.33 ghz) burns a DVD DL after blowing compressed air thru the DVD slot. But the second DVD DL fails to burn with the ""The disc can’t be burned because because communication between the computer and the disc drive failed (error code 0x80020022)."
I was hoping that the upgrade to 10.6.x would solve both issues, but not so much.
Anyone else with the DVD DL problem experiencing FW problems?

The problems with some external FW burners under SL are fairly common, Robert. With some earlier drives (like my Pioneer 109 in an external box) often one can't even "see" the drive at all (though the bridge in the external box will show up under System Profiler) through FW, though it works fine under USB. With some later ones things like PRAM resets, or simply disconnecting and reconnecting the drive, will get them working. See http://discussions.apple.com/message.jspa?messageID=10070281 or some discussion of these issues and possible "workarounds".
As far as the general disc burning issue goes, other things that are worth considering include problems with a "fullish" hard drive with fragmented free space, and the actual media being used. What brands of DVD have you tried?
DL discs, generally seem much more finicky about dust and dirt than single layer when it comes to burning (and , of course, need much more free HD space) . Will it burn a single layer DVD or a CD without problems?

Imac and external projector resolution problem!!!!!

hello! I´ve benn using an imac24" for about 4 months. When I attached my projector with a capasity for 1024x768 85Hz while my imac´s is 1920x1200.
My problem is that I want my imac to use it´s highest resolution at 1920x1200 while my projector is using 1024x768. Is that posible, and if, how would I make it happen?
//Wilhelmsson.
Imac 24", core 2 duo Mac OS X (10.4.10)

You can only do this if you have the system set for "extended desktop", where the images on the two screens will be different. If you want to run the system in "mirroring" mode, where the iMac's screen is duplicated on the projector, then the resolutions have to match, so you'll have to reduce the iMac's screen to 1024x768 to match the maximum resolution of your projector.

I have just bought an imac and I am having problem with my camera. The image is kind of distorted and coloured lines everywhere. I have updated softwares and applications and restarted the computer but it didn't help. What to do?

what to do?

shauney,
From your description of the problem, it sounds like you have a hardware/camera defect. My recommendation is to return your imac to where-ever you bought it, and have them deal with, or replace your computer with one that functions as it is supposed to. You should not have to suffer with this situation on a new computer, although it does sometimes happen.

I5 iMac and Firewire question...

I have a Firewire 400 external hard drive that I need to hook up to my new i5 iMac. From what I've read, I need to buy a 6-pin to 9-pin Firewire cable. Right?
If I read right, FW400 is 6-pin, FW800 is 9-pin, and the small FW connector seen on DV cameras and such is 4-pin?
Thank you for making me less of an idiot

Yes that is right!
To go from FireWire 400 to 800 you will need either a cable or an adapter:
9 pin 800 to 6 pin 400 > http://www.firefold.com/9-Pin-to-6-Pin-C54.aspx
or this adapter > http://www.sonnettech.com/product/fw_adapter.html
For a camera with a 4 pin Firewire connection you would need the following:
9 pin to 4 pin > http://www.firefold.com/9-Pin-to-4-Pin-Firewire-Cables-C53.aspx
The FireFold (cable's) and Sonnet (adapter) above are just examples that I used, thay can also be found on line at OWC, Cables to Go, Your Cable Store or at most of the larger Computer/Electronics' outlets.
