I have the Mac Pro and I have an external hard drive that I connect via the front FireWire panel on the Mac Pro. When the drive is off and the FireWire cable is connected to the computer, I get a "buzz" in the speakers. When I turn on the drive or disconnect the cable, the buzzing is gone? Any ideas?

Okay, So i have my Unibody Macbook Pro (late 2009) hooked up to external speakers (RCA Home Theater system with a standard audio cable). Everything works fine and there is no buzz or sound except for the music of course until I plug my printer in. I know the obvious solution is to unplug the printer when listening to music but the printer is shared and other people print off of it etc. and I was wondering if anyone knew why this happens.
View 1 Replies View RelatedI hope I'm not double posting. Have any of the other new iMac owners experienced weird frequencies coming from external speakers that are connected to their iMacs?
For example: I have a set of studio monitors that are hooked up to my iMac using a firewire audio interface. Whenever I'm copying data I get an extremely high-pitched frequency coming from my speakers that sounds like my hard drive spinning. Also, whenever I'm scrolling or moving the magic mouse I get a loud buzzing coming from the speakers (especially when scrolling). None of this stuff happened with my previous 20" iMac C2D. I have experienced this issue with all three of the 27" iMacs that I have gone through thus far (due to the yellow tint issue). Does this sound like something I'm just going to have to live with. All of these high pitched frequencies are driving me batty!
I have the new MacBook Pro Retina, which I absolutely love. The only issue so far is that the speakers buzz sometimes. I've tried different equalizer settings, which helps somewhat. Has anyone else experienced a buzzing or distortion in their audio output? It almost sounds as though a speaker is blown.

I just purchased some logitech 2.1 speakers for my Macbook Pro, and unfortanetly, there is a pretty noticeable hum or buzz coming from the speakers. When I have the volume for the speakers turned all the way up, and the volume on my computer on mute, it's most loud. It's quite annoying.
I feel like I had this problem with my previous speakers (without a subwoofer) but I resolved it somehow...What to do, what to do...
I consider myself very good at all things Mac. But this one has me stumped.
I've just arrived home with a WD My Book Home Edition 1TB external drive. Formatted for Windows it mounted correctly via FireWire and USB.
First things first: I formatted it for the Mac... Mac OS Extended (Journaled), two GUID partition tables. So far so good. Each partition is recognized, each mounts like it should.
Time Machine then backed up my Intel iMac... again, everything's normal. No odd or unusual behavior.
Here's where things get strange.
For whatever reason I formatted the drive via USB. But my intention hereafter is to connect via FireWire... I need each USB port for peripherals.
But the drive isn't recognized through FireWire. I'm asked if I want to initialize it. When reconnected through USB the drive mounts again.
What's going on? Why is the drive recognized when connected via USB but not when connected via FireWire?
The firewire port on the front of my machine is bad. I can't transfer any kind of data using it. The port on the back as well as all USB ports work fine. Would this need a complete motherboard replacement? Would it even be worth doing? Could I build a dual processing machine or buy one cheaper?

My front firewire 400 and 800 ports abruptly quit working. THe backs work fine. I've tried two different video cameras and an external hard drive and according to system profiler none are recognized and none are accessible.
I have a 2006 Mac Pro and recently my firewire ports stopped working (front and back). I did a little searching around found a suggestion to try resetting the Mac's PRAM and NVRAM by holding the Cmd-Option-P-R keys down while booting. I have tried this numerous times and it doesn't seem to do anything (i.e. the Mac just loads OS X and doesn't re-boot like the instructions say). I'm using a MS Wireless Comfort Keyboard for Mac. Can you reset using a wireless keyboard?
Since I wasn't making any progress with that, I was toying with bringing in the Mac to a genius bar. Never having used the genius bar before - how does it work? Do I bring the computer in and leave it with them? Do they work on it while I'm there? I don't have an extended warranty so do they charge time and materials? I'm wondering if that might get awfully expensive and if I ought to just buy a PCI-X firewire card instead.
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?

Just got my 15 LED SR Macbook Pro. When I plug my bose speakers in at my desk and listen to itunes, I am getting a static pop sound. Should I take it back or is it fixable? By the way, LG panel and no yellow 1/3 of screen. Initially thought it was yellow, but I calibrated it, and now it only looks yellow if viewed from the side. Head on, white. One thing I have noticed, when I watch movies on it in the dark with the brightness turned down (cause this thing is a torch), I am getting quick flashes when a screen has high contrast light and dark. I am very sensative to LCD flat panel TVs that use a colorwheel. Like a JVC dilila, I see rainbows! Is that normal for an led flat panel to see "quick white flashes of light"?

The classic "bong" sound at startup, I know that is the result of a successful POST, but mine didn't do one after the 1st startup. I had speakers plugged in to it when I started up the 2nd time, and no sound. I unplugged the speakers, and I got the sound. Is that normal or do I need to contact Apple? I jut want to make sure nothings wrong with my iMac. I checked the POST results in System Profiler and it said Passed.

I'm a recent PC to iMac convert and have hooked up my iMac to my TV receiver (DVI to HDMI connector and a Toslink cable to the audio). The issue is as soon as I plug in the audio connector the iMac speakers stop working. I'd like to leave the connector plugged in and still be able to use the iMac speakers. Of course when I play a movie on the TV I'd just mute the iMac speakers.

I have just ordered a Macbook Air. I have an external monitor that has speakers seperate. If I use a minidisplay port to hdmi adaptor to connect to the monitor, will the sound be able to be played out of the speakers of the Air? If not, can I connect an audio jack and have it play through the seperate speakers?

I searched the archives and I can't believe no one has mentioned this yet! This is a huge problem on both my Rev A and my new Rev B. When you connect an external monitor and external speakers using the headphone output, there is a high frequency ringing sound coming out of the speakers. I've managed to live with it by turning the treble to minimum and keeping the volume low enough but at the expense of sound quality. The strange part is, if you disconnect the monitor, the ringing sound stops. The problem only occurs if you have speakers and monitor plugged in at the same time. I've tried this on my Samsung monitor, my SONY TV, and my Panasonic audio receiver. The problem occurs with both Rev A and Rev B while my white MacBook and 2007 MacBook Pro all sound fine.
View 10 Replies View RelatedI have iTunes 10.6.1 (7) an Airport Extream Version 6.0 Airport Utility (600.92) That I use with two airport express stations, an Apple TV 2nd Generation with latest software up date. Also have Ipad 3rd Generation and two I phone 4's. Issue: After installing the latest Airport Utility software update I'm unable to connect to my remote speakers in iTunes. The speakers are visible in the pop up menu but iTunes times out when trying to connect. If I use remote to select Apple TV and then via Apple TV select my Computers Library I'm able to play music on the Apple TV / Home Speakers... but still not the Airport Express Stations.
When using remote on the iPhone or iPad the speakers are visible as well but I'm unable to select them... iTunes times out. I can steam music from that is on my iPhone or iPad to each individual speaker, but multiple speaker control is not available and the music from my library is not available. I believe the problem is in the Airplay feature of iTunes and I believe the problems arise when you install the latest version of Airport Utility. You can play on remote speakers, only one at a time, and only if you have the music on a stand alone device (iPhone or iPad)... in summary, bypass iTunes and you can be successful... marginally successful.

Any news of Front Row in Lion? Apple is selling the mac mini without any new interface? Apple really needs to offer us something over front row which I don't think has been updated since 2007. So Apple how about it?
View 4 Replies View RelatedI am getting random (at least it seems random to me) buzz sounds coming from my 2009 2.66 Mac Pro that only lasts for a second. Some suggestions from the other threads recommend that I touch the case when it buzzes but by the time I reach for my MP the buzz stops. I've tighten all the screws in my sleds and pushed them so they are snug in the bay.
Some have thought the buzz comes from the latch but my buzz sounds like it's from the front of the MP. A Mac Genius told me circuit boards can make a buzz sound from electricity going through it?
Others have said the buzz comes from the PSU (power supply unit). Where is the PSU in the MP?
I haven't shaken my MP, which is one of the suggestions I read.I think it might be coming from the Super Drive. I took out the Super Drive for about a week and don't recall hearing any buzz sound.
rgetter recommended re-aligning the ribbon cable (see quote of his post below), but how do you do this? I didn't see a ribbon cable when I took out the Super Drive.

I have a less than 1 month old White MB. I have become aware of an electronic noise emanating from below the upper left portion of the keyboard, under the q,w,e keys. The noise can be best described as a mechanical mosquito; it is a constant high-pitched buzz that starts once the computer has fully booted up, and doesn't stop until it has been shut down. Although it is quiet, if you get your head anywhere near the keyboard it is readily apparent and obnoxious. It does NOT appear to be fan related, as I can hear those going as well. I have listened to other Mac laptops with equal scrutiny, and this noise is not present.
A simple Google or Apple forum search indicates that people have been noticing this problem for years. Indeed Apple appears to have acknowledged it recently with MB Pros: (URL) I believe it indicates a faulty logic board.
- Have others noticed this with their MBs or MBPs?
- Does anyone know the true source?
- Most importantly can anyone give me some tips with how to deal with Apple on this?
They have suggested I go talk to the store I bought it from. Those guys claim not to hear it (a common theme from what I have read). However, this is highly dependent on the level of ambient noise and hearing ability of the individual. I already had to return one MB that was DOA, and now I have this one. Given the expense of this purchase and the age of the machine I feel that I am entitled to a new one that does not display these issues. How can I effectively communicate this to Apple or my retailer, neither of which will likely want to comply?
I made a thread a couple of weeks ago this kind of a problem. I did no get much feedback but am eagerly looking to hear from people since this problem has been driving me nuts for a couple of weeks now. After audio has been started on my Macbook Pro there is screetch-like noises/alien/spaceship/buzzes. it eventually stops but starts after there is audio again
