I started to notice a "popping" noise (about 1 Hz) when I got external speakers for my Mac Mini. It occurs when the Mac is sleeping and the external screen is on (but sleeping its own "sleep"). If I disconnect the analog audio out (from where the external speakers take their signal) the popping ends. If I connect headphones to the same jack, I hear no popping in them. If I hit the power button on the external screen and power it down, the popping ends. It will not return even though I power the screen on again.If I disconnect the USB cable that power the speakers from the Mac, the popping ends, but returns when I connect again.
On my 13" MacBook Pro, the hinge makes a cracking noise on the right side of the computer (near the power button) when the screen is positioned all the way back.The entire hinge also makes a loud popping noise when I adjust the screen position. The screen seems very tight, and it takes a little bit of effort to move the screen, and when the screen is moved it makes the loud popping noise.
This is probably going to make some of you guys cringe, but sometimes putting pressure down on the top of the case close to where the black hinge meets to unibody enclosure seems to stop the popping noises. Putting downwards pressure on the hinge, or flipping the computer over and putting pressure on it that way, also seems to alter how much popping noise there is.
If I mess around a bit with applying pressure on different parts of the computer around the hinge, I can usually eliminate the noise. But, the cracking noise when I put the screen all the way back is still there.Any ideas what to do? It's not interfering with the operation of the computer, it's just incredibly annoying and this is only a four month old machine which shouldn't be creaking and cracking already.
I just received my new MacBook Pro (2.4GHz) to replace my older CD Macbook Pro from 2006 which was suffering fan problems.
My new MBP is great and faster, with the exception of a really annoying "popping" sound that is coming from the left hand side of the laptop. It's sporadic and might happen every few minutes, or every 30 sec. or varying lengths of time in-between "pops."
I searched the forum hear and didn't come up with virtually anything at all, but the Apple Support Discussions had several threads on the topic, most pointing to the Hard Drive and the sound possibly coming from the heads parking on the disk.
Could anyone offer any advice on the subject? I just got this brand new MBP from AppleCare and really don't want to have to go through all the work on getting another replacement if this sound is normal.
Everything works perfect except this one thing. Was wondering what you guys thought of this problem. Didnt return it because i was hoping that it would go away with wear in. I checked the back, nothing is coming out of place, its just theres a sound when i open the macbook after its been closed for more than 20 minutes.[URL]
Yesterday my speakers stopped working. It's not software based, the audio drivers are working properly. Whenever a sound that is over a certain volume is played, you can hear a pop come from the speakers. For instance, if I play a song that has fluctuating volume, every time the volume goes up, there's a pop, and every time it goes back down, there's a pop. The volume the computer is set to doesn't effect this. Even if it's muted, there's still a pop that's the same volume as if the volume is turned up all the way. Any ideas what could be causing this?
Occasionally I'll be listening to music or just changing the volume and a sharp popping sound will occur from the internal speakers and then they shut off. No sound can play it all. To fix the problem I just have to reboot and then the speakers work fine. Does anybody know why this happens?
This happens on my iMac sometimes and it just happened on my new MacBook Pro and I'm wondering if it's damaging the speakers in any way.
Edit: I don't remember what I was doing on my iMac to cause this, but I do know what caused it on my MacBook Pro. I was recording my canary singing (don't ask why) using Quicktime Pro, and then listened to it (it worked fine). I imported it into GarageBand to crop it and when I previewed it there to figure out where to crop the file, my speakers popped and GarageBand gave me a warning about the current track not being optimized or something. Note that never happened on my iMac.

I recently purchased a mac mini which i use as a HTPC. A lot of the time i use VNC to connect to this machine when i'm not using it as a HTPC. The problem is that it always goes into some sort of sleep mode when i haven't used it for some time. I'm not to familiar with the ways in which a mac can sleep/hybernate but what i'm looking for is a way to let it sleep but still allow me to connect to it through VNC. Alternatively i'd like to be able to remotely wake it up somehow.
Ever since I reformatted my Mac a few weeks ago, I've had some interesting new problems. I've been told for some of them that it is because before my reformat, my Mac was updated from Snow Leopard, and carried over some stuff into Lion.
This problem involves iTunes 10.6 and streaming to a second-generation Apple TV. (The 720p version, but running iOS 5 that came out with the new 1080p Apple TV) The problem involves my Mac going to sleep. I can fix the problem, but it works differently than it used to: Before, my Mac went to sleep after three hours of inactivity; if my iTunes library was being accessed by my AppleTV, iPhone, or iPad using Home Sharing, it would never sleep as long as it was being accessed remotely. Now, however, it will still sleep if it is being accessed, which causes problems since my Mac is on the other end of the house from the Apple TV, and I often run it for more than three hours when listening to music as ambiance or watching a television/movie marathon from my iTunes Library.
I can set my Mac to never sleep, but I would prefer it would still sleep after the three hours -- assuming it wouldn't sleep while accessing it from Home Sharing.

Whenever i put mac macbook pro to sleep, it only stays sleeping for about half an hour and then wakes itself up. It does it whether i close the screen or manually put it to sleep. When its awake, the system is running but the screen is dark unless i click a button.
I am using a Mac Mini with my home theatre set-up and when the Mac Mini is connected to my stereo using a 3.5mm Stereo Plug/2 RCA Plug Cable I get constant crackling and popping from the speakers. I've tried a new cable (didn't help) and tried plugging the Mac Mini in to a different outlet.
The cable connection at the back of the Mac Mini feels a bit loose but it seems like that's the way it's supposed to be rather than any sort of hardware issue.
I just got a mac mini on thursday, went on a small trip on friday-sunday. When i came home to my sleeping mac mini and woke it, it made a TERRIBLY loud fan clicking noise. My old PB 12" made this noise after I had dropped it on floor from about 3 feet. I didnt drop my mac mini, i barely used it for 2 hours before i had to leave on my trip. The sound eventually goes away though, once the mini heats up a little i guess. So i'm pretty convinced it's the fan, but why would it suddenly do this?
Just got it today. When I sleep it, a quiet but audible noise kicks off that increases and decreases in intensity with the light on the front of the unit gets brighter and dimmer (so sort of sinusoidal). I've tried restarting it and resetting the SMC. The unit got upgraded to 4Gb ram and a 7200 320gb hard drive today. But I don't believe it's the hard drive - that makes a very low key monotonous whine that stops when I sleep the unit.
Been working with a new mac mini in my office the last 2 days. The power settings are set to make the display only go to sleep after 15 minutes. System set to never go to sleep and hard drive never spins down. 3 of the 4 times since working with this thing when moving the mouse to wake up the display I get nothing but noise and snow on the screen. To get back to functioning correctly I have to put the computer to sleep with the power button and back on again. Once it comes back, it will work fine. New mini 2.4 running 10.6.4. Monitor is hooked up via DVI through the mini display port.
I'm getting this softly high pitched sound at idle. I did not have this sound before until this month. I bought this thing in January 2010, yes this year. Does anyone know what could be going on? It does not make that sound when I'm using it, it's only at idle. I can even hear it when I'm lying in bed since this is in my room. Check out my signature to see what I have.
It sounds like a idle fan issue? The computer works fine, but it's just that high pitched noise that bothers me. I should take it to the apple store huh?
I decided to keep my current set up and use my mac mini as a desktop that mostly works as a media server like set up that holds my media for my apple TV if I run out of space on the ATV and later use it as a home theater computer when i get another HDTV. this is just fyi on why I have my mbp and mac mini still yet instead of having only one computer...
I just got my 2.0ghz Alu Macbook a few days ago and everything works perfectly well, the thing is that after day one the magsafe started to emit a low pitched electrical whistling noise. It tends to be there a few minutes after booting into the OS and then it turns down to almost unhearable, but I experienced it returning after a few hours of use and then disappearing again. If I move close to the escape key I can hear a crackling noise emitting from the magsafe.I'm not trying to be overly nitpicky or anything but I read somewhere that if it's doing that it would be a faulty Mag-Safe board or something.
Does any one you guys know anything about this? I have the 14 days to return it as I bought it online from the Apple Store so if it's a faulty part that might die/break/ cause problems later I might have to.
Sometimes I lift and carefully move my 17-inch MBP a short distance to another flat surface without putting it to sleep mode, it starts making really loud mechanical noise when I put it down, so loud that people in the same room can hear the noise and I can feel vibrations too! What causes this? Where does this noise come from? Is my MBP defective?
My first generation unibody Macbook hasn't had any problems to this date but now it's constantly making that mechanical loading-like noise which is usually heard when the Macbook is switched on (the noise before the start up sound) or when the lid is opened to wake up the computer. Is there a fix to this?
Has anyone else had problems with an old G3 Pismo making an annoying squealing noise when plugged into a charger? There's a lot of noises mentioned in mac/apple forums but none of them relate to this one. Here's what it is not:
It's not coming from the screen or the fan or the speakers (it's under the keyboard). It's not low or slightly annoying (it is a loud squeal). It happens only when the power adaptor is plugged into the laptop.(it used to cease after I unplugged the power adaptor and plugged it back in three times; now that solution doesn't stop the noise anymore). It charges ok, and runs ok, scream or no-scream. It's quiet right now, but if I move the adaptor to another plug it will start again.
I was going to live with this, but today after an hour of operating quietly it just started again, and I hate to leave the house with this going.(it will scream whether the laptop is on or off. I have a really old battery and cannot replace it (I am currently staying in Mexico for the summer). Battery life is 45 min. I haven't tried pulling the battery out. That would be too easy.
This all started when I bought a replacement power adaptor (generic),after the original one melted down, but I could stop the screaming by unplugging/plugging it in again once or twice. Then I bought an expensive iGo adaptor, and it does the same thing.
I Did the PRAM and PMU reset.I can hear it over music or the tv. It grew lower in pitch today after squealing for a half hour. I'd normally not let it go on that long, but i was in the other room.Is my PISMO dying?

I'm new to this forum and I just bought a new iMac 20" 2.66GHz, I turned on my computer and noticed a weird sound (buzzing or humming noise) not loud but loud enough to here I notice when I messed with the Brightness it went away is there something wrong with that or is that a known issue?
I just got my macbook pro yesterday and ran it all yesterday not hearing anything. Today when I woke it from sleep I could clearly hear the fan or hard drive going. I was in a quiet room and it's quite annoying.
istat says its at 2000 rpm so thats when I started thinking it may be the hard disk. It does pulse every now and then but thats even while it's just sitting idle.
I guess I could live with it but its just annoying. Anyone else having this?
I have santa rosa 2.6 mbp with recent firmware update running Leopard 10.5.7.
It seems since then MBP will not always sleep when told to via screen menu in top left, it hangs on a bluey grey screen instead of transitioning to normal black power/lights out screen for sleep mode.
Only way to fix is by holding power button down..
There is an old thread about same problem but with no solid conclusions as to why so i though i would see if anyone has any new ideas as to why this is happening?
Ever since I reinstalled 10.5 last January, my MBP (early 2008) refuses to sleep automatically - it works fine if I direct it to sleep manually or close the lid. I had hoped that 10.6 would fix this issue, but it has not. All the settings are correct under System Preferences, so I have no clue what is going on.
I have been using my Black 2006 MacBook religiously like this:
1. Startup in the morning around 9:00 am,
2. sleep wake sleep wake wash rinse and repeat the whole day till...
3. Around 11:00 pm a full shutdown at night.
Then a full repeat of 1, 2, and 3, everyday for the past 2 years +.
I have a new idea, because I have a serious routine I go thru, setting up my work environment, that takes about 45 minutes to an hour every day in the morning after step 1 above. The new idea is simple, I want to leave the MacBook running, in sleep mode of course, over night. Leave it all setup and just resume where I left off instead of starting up every morning.
Does anyone have any experience running like this? I shutdown every night and I haven't had 1 problem with my MacBook. I just don't want to have any problems. I think that this style of workflow won't be any stress, but with this setup I would never shutdown or restart unless I seriously have too. Restarting just wouldn't happen... it's just I think of my machines as alive, and I feel like it would suck if it never got that refresh feeling of never shutting down and being completely off for a 8 hours.
Lately, I have something popping up in my Dock for a very short amount of time. I can't see what icon it is because it's already gone. I know it's there, because space is being made for in the Dock.
Is there any way to find out in some log what this could be?
Also, mac os x does not want to stay asleep. I put it to sleep before turning in myself and every morning the screen is fully lit.
I am always concerned about unauthorised access by third parties.
