MBP noise issue.

Hi....
I have a mid - 2012 MacBook Pro. Whwn the Turbo Boost kicks in, and the laptops gets hot, the MacBook starts doing a noise that sounds like... clicking?
It definitely sounds mechanical, and it also sounds a bit like something is loose as the sound becomes a bit weaker when I push the cover of the MacBook.
I have a suspicion that it is something to do with the left fan.
When I close the laptop and let it go to sleep and then open it again, the sound is gone. Unfortunately, only to come back every now and then.
What could this be?
If it really is the fan, is there a way to fix this without getting a new one or taking it to a Genius Bar?
Thanks.

If you have not tried already, try reset SMC.
Reset SMC. http://support.apple.com/kb/HT3964
Choose the method for:
"Resetting SMC on portables with a battery you should not remove on your own".
If there is a mechanical problem, it is better to take the computer
to the Apple store to have it fixed.
Best.

This is a workaround for the MBP wireless issue

There have been many topics on the MBP wireless issues already, but I thought some people might find this workaround helpful.
Firstly, my system is a 2.2Ghz MBP, running 10.4.10, and also airport extreme update 2007-04. I am using an airport express base station. My previous Powerbook never had any wireless problems, so I really couldn't blame the basestation for the MBPs poor wireless.
Warning - The workaround requires a little bit of work in the terminal. A little bit of understanding of how networks work is assumed here as well. So it is probably not for everyone ...
What I have observed - whenever the MBP loses connection, the airport basestation IP and MAC addresses are missing from the ARP table.
- To view the ARP table, type (in a terminal window) arp -a.
So, when the MBP wireless hangs, open up the terminal and type that in.
Do a Cntrl-C if the arp command is hanging and not returning anything.
In normal situations, a list of IP addresses and MAC addresses will show up.
As others have already noted, clicking on the airport icon in the menubar, will magically bring the wireless back to life. When this happens, the ARP table also gets magically populated correctly. Coincidence? I think not!
So, the workaround is to store a PERMANENT entry in the ARP table for the airport basestation IP and MAC address. In my case, I can use the Airport Utility software to confirm what the basestation IP and MAC addresses are (note MAC address = Airport ID in Airport Utility). I found the basestation IP=10.0.1.1 and the MAC=0:11:24:07:d7:f
To create a permanent ARP table entry for my airport basestation, I opened up a terminal window, and did the following -
1) login to my administrator account
2) type in the following command sudo arp -s 10.0.1.1 0:11:24:7:d7:f
3) type in my administrator password to authorise the change
4) type in (to confirm the changes have been made) arp -a
5) logout of my administrator account (from the terminal)
Ever since I did this, my MBP wireless performance has been flawless.
Note, if you shutdown or restart your computer, the arp entry disappears. This is ok for me as I hardly ever power down my MBP. As insurance I have added an account startup item to remind me to do the arp table entry.
This workaround is great for me because I don't have a need to use multiple wireless networks. It might not be practical for people who roam around onto different networks.
Give it a go and see if it works for you.

OK, after some further experimenting, I changed the multicast rate on my airport express. It was set at 6Mbps, and I changed it to 2Mbps.
I have read that the default multicast rate for previous 802.11g versions of Airport basestations is actually 2mbps. Excellent results so far !! I have set up a terminal command to continuously ping my airport router address every 15 sec, and there have been virtually no dropped packets so far over many hours.
ping -i 15 10.0.1.1
Interestingly, in Apple's Airport Admin software in my MBP there is no option to set the rate at less than 6Mbps (!!!!), so I had to use the Windows XP version of Airport admin software to make this change using a windows machine. Using the XP software you can set the muticast rate as low as 1Mbps.
If you are using Apples airport admin software (Tiger and Leopard) and you commit any sort of change in settings, the multicast rate will be re-set at a minimum of 6Mbps. My understanding of the multicast rate is that setting it too high is similar to shrinking the coverage area of the basestation, and limiting access only to clients who can transmit at the required multicast rate.
So my new theory is that the dropouts are caused by the MBP dropping off the airport due to not being able to achieve the set multicast rate. (this could be due to factors such as low signal strength, excessive interference or noise).
If you are using Apples more recent Airport admin software, you are having a minimum 6mbps muticast rate set, and this might be too high for your particular environment.
Just a theory.
(oh yeah, I enabled interference robustness on the MBP and the basestation just for good measure)

Noise Issues

I know everyone has probably posted about these same noise problems before, but only one or two people posted audio of their noise, so I don't know if we are all on the same page or not.
I have two completely distinct noises coming from my MBP (it is a 1.83 all stock with just RAM upgraded from Apple).
The first one is a hum noise (I know this one seems pretty prevalent) that comes from the right speaker area and goes away when at full brightness or backlight off. Here is a link to a video of the noise:
http://homepage.mac.com/jimdufek/mbp/movies/humming_noise.mov
From what I gather, this is a problem with the power inverter for the display and can be fixed by shipping back your MBP. Has anyone that had this problem shipped theirs to Apple and gotten it back? If so was it fixed properly and how long was your wait?
Second noise issue is a bit weirder. It is a squealing noise coming from somewhere in the middle or under the keyboard. It is very infrequent and if I move the MBP at a slight angle (as if it is resting on my lap) the noise goes away. I have tried PhotoBooth, Bluetooth on and off, Airport on and off, volume max and min, AC power and just battery life and none of them have any change. The noise only lasts for a few seconds and then is gone, but will come back in 10 seconds or in two hours. Below is a video of that noise:
http://homepage.mac.com/jimdufek/mbp/movies/squeal_noise.mov
Again, does anyone have this noise and if so did Apple diagnose it and fix it yet?
I want to get my MBP fixed, but am worried that this second noise is something they will miss and I will ship my MBP only to still have this noise. I am thinking about taking it to an Apple Store (since they will hopefully be able to hear this problem), but can they fix it in store or swap it out for a new one in store?
Sorry for being so long winded - thanks in advance!
DISCLAIMER: The audio in the above videos was boosted on the camera - it is NOT that loud in real life, but it is audible with no electronic devices.

ouch that is annoying! but if its not that loud i
dont think you should be posting it at all, it'll
give a wrong impression, because that sound at that
level is annoying. but thanks for sharing!
"if its not that loud i dont think you should be posting it at all, it'll give a wrong impression". What in the world are you trying to say?! I have this same problem (two different types of whine/buzz) and it is REALLY annoying and it deserves to be brought to everyones attention. "It'll give a wrong impression"???? What the ****! GET A GRIP! Its exactly as he/she said it is. ITS ANNOYING and untill you hear this buzzing noises comming from your minute old, $3000.00 MacBook, I really don't think you will understand how bad it is.

Nikon Images, Noise issues in Photoshop only

I use Nikon cameras and shoot raw files processing them in ACR and then bringing them into Photoshop. I notice that after the images are processed and saved as jpegs. when I look at the final image in a Microsoft film strip browser, the noise which shows in Photoshop disappears in that viewer. In Photoshop I am viewing everything at 100% I cannot figure out how that happens and what is the true quality of the image. I am just wondering where I can see the true final quality of the image. I would rather not use any noise reduction on the images. I do not like the quality of the image after using that tool.
I also shoot with Canon equipment and I never have and noise issue. I am aware that Nikon has noise issues at higher iso's and when the image is underexposed but I am taking that into consideration when processing, I also process in light room and Nikon capture but in those products I know that they have some different algorythums to correct the noise.
Thanks for any comments or suggestions on this issue.

Photoshop is color managed and is using your monitor profile in an attempt at accurately portraying your image. Most image viewers are not color managed.

BlackMagic HD Decklink Noise Issue

Hi all,
Im experiencing a noise issue when broadcasting and capturing with my HD DeckLink BlackMagic Card. This weekend I was broadcasting live using the LiveKey application and I was experiencing a lot of noise in the transmission of the event. Connection was NTSC (Y in) and (Y out) this also happens using the Y, R-Y, B-Y connection too. Please help!
Regards,
Robert C.

I haven't really used the LiveKey application - have you contacted Decklink's customer support? They've been responsive for me in the past...

The Ever-present Fan Noise Issue

Has there been a definite resolution to the fan noise issue on the iMacs? My 20' started after about a week while I was watching a movie. I can't really work on it without having iTunes (or some other noise) in the background.
A while ago, I read a post about having it narrowed down to the "Optical Drive Fan" (or something like that) being loose/broken/cheaply built (perhaps a combination of the three) and it made sense when I looked at the back of my mac and covered the vent to listen to the difference.
I haven't heard about anyone getting this fixed and the problem being solved, but I would certainly like to. From the sounds of things, some Apple techs are a little premature to replace logic boards and mid-planes and things of the like. The one that I talked to "hadn't heard" of any noise issues and thought it might be a power supply, but I haven't had the time to take it in yet.
If someone has a definite solution (more than just speculation or complaints), I would appreciate hearing. I don't feel like waiting 1-2 weeks for a part that I don't need, if I just have to take it in to the tech for 45 minutes to tighten a fan.

programs it didn't open: limewire, clamav,onyx, menumeters, my driver for my mouse, and a few others.
CS2 took a while to load as did mac office.
the rendering in CS2 was aweful! now i know why steve said it was no good for pros.
the native apps were quick but not enough to sell me on it.
i had a rev a imac g5 with 2 gigs of ram and it screamed.
i plan to make out my new 2.1 with 2.5 and she will scream as well.
the intel duo is nice..if you like to look at activity moniter and see to cpu's but to me its not worth the hassle of dealing with beta apps and all that.
the g5 is more than capable of handling all my tasks and themsome.
i'm gonna wait to upgrade. unless they come out with something amazing this year.

Firmware 1.1 White Noise Issue

I upgraded to 1.1 from 1.03 and do not have the white noise issue at all. Have 2,000 songs and bunch of videos and about 100 pics. Had 0 problems, iTunes and iPod update all went 100% smooth.
Saw some bad reports, just wanted to let those thinking of upgrading that the problems mentioned do not occur 100% of the time.
I also have no unusual noises and never have had the battery draining problem.
160Gb Classic

It is totally random, there is no pattern to it. It was the day after I updated to 1.1 before the hissing started on my player. It hasn't happened so far today but it may happen later on tonight. I had no issue with the update and all my music, photos and videos remained intact but the hiss and thumping noise you get when you remove the earphones is a real bummer and a total let-down with this new firmware. Check to see if you get the loud noise when you remove your earphones; if you are you may very well get the hissing. It's certainly happening to the majority.

A New MBP Noise?

I know all about the reported noises from MBPs, but I think that I have found something slightly different. When I connect the MBP to analog speakers via the headphone out port, there is a terrible hissing noise coming from the speakers. I tested the same cables and speakers with a new MacMini and had no problems.
Has anyone seen this problem yet?

Very easy way to test it. Plug in your speakers and open Photobooth. If the noise stops, your MBP is plagued by the famous whine. If not there must be some interferences caused by the MBP internal components, or external sources.
Either way, its annoying. I haven't noticed that running my mbp on a kenwood amp. But this and other issues make a mockery of the PRO suffix of the machine.
Cheers.

MBP startup issue

Hello,
I was wondering if anyone else has run into this or may have some insight. On two separate occasions I've tried powering on my MBP and after hitting the power button it would come on, I could hear the hard drive spinning up, but then it would power off almost immediately. I didn't know about resetting the PRAM or SMC, so I didn't try that. What I ended up doing was holding down the power button until the MBP made a noise and then it would start up ok. So perhaps I inadvertently reset the SMC without realizing it and that fixed the issue? I did not disconnect power or pull the battery when I did it, so I'm not sure.
Has anyone else's MBP exhibited a similar behavior on power on? I guess I'm worried that it might be a hardware issue that should be resolved. It's not something that's a frequent occurrence though.
Thanks!

I wouldn't drive all the way to an Apple Store, their policies are probably identical to the ones expressed over the phone. I would search for a local Apple Authorized Repair Shop in your area, and bring it there to see if they'll service it. They'll honor your warranty so it will be cost free, and they won't have the tough stipulations that Apple does concerning your warranty.

Macbookpro noise issue on right side with heat

Hi, my 2014 macbook pro ratina display,13 inch, just finished a years warranty period, and suddenly from right side of the laptop, a noise starts (like a modem connecting or something burning kind a noise) with upper right corner more heated then the rest of the laptop, Can someone help out with the issue ?

my ginger wrote:
Aha. I think I was thinking of the 15 inch. Thanks for the heads up.
It is not that simple. The late 2012 13" retina MBPs and the early 2013 13" retina MBPs have two fans installed. Starting with the late 2013 13" MBPs, only one fan was installed.
Ciao.

MBP Logicboard Issue. Help!

Hi, Im from Argentina and had a serious problem with my MBP early 2008.
Just 2 days ago I woke up and turn on my computer as usual, but it didn't work. I had the dvd start noise then the sleep light on and nothing more. Completely dead!. I been trying all kind of key command & combination already posted in this forum with no success.
Then I decided to go to Apple Store where they diagnostic that I need a logicboard replacement by 700usd + shipping cost.
They said there's a known issue (http://support.apple.com/kb/TS2377?viewlocale=en_US) but as my computer won't turn on they can't verify this.
I can't belive how a 2 to 3 years old laptop has a defect and they want me to pay that much.
At another store they said that few MBP with same issue was already diagnosed and Apple US had replied that 'there's nothing we can do if it can't run the test'.
I just want to know if anyone can give me straight answer, and let me know if there's something I can do before pay that much for a relative new computer.
For the record, here in Argentina my used computer cost like 1000usd (working computer). So you can imagine that logicboard replacement is like that.
Thanks

A common problem with forums like these, which are invaluable in many ways for many people, is that once a forum thread starts to get big (say, 50-75 or more posts), it attracts a lot of "me too!" posts from people who don't take time to read the other posts and think about whether they really have the same problem themselves, or whether their own problems have different symptoms, occur under different circumstances, or occur on very different hardware.
By the time any thread here has 100 posts in it, it has invariably become a milling, angry crowd of people who all think they have the same problem, but who in fact have a multitude of different problems arising from different causes. It becomes impossible to keep them straight, and it becomes impossible to focus attention on any one problem, because others are always interrupting any attempt to do so with their posts about other problems. Longtime users of the forums just ignore such threads once they grow to the point of complete uselessness. There are threads in these forums that I haven't looked at in more than a year and will never look at again for this reason.

Mid '09 MBP bootup issue - flashing folder; possibly a fried drive?

Hi All,
This is my first post here. Today my 14 month old MBP 15-incher froze in the middle of some casual browsing/iTunes listening and decided to not respond to any mouse or keyboard input. I gave it some time to figure itself out and then after about 5 minutes of nothing, decided to force a shutdown by cutting power (10 second power button hold). Then upon my next boot the computer gives the chime, shows the grey screen (no  logo), does nothing for ca. a minute and a half and then presents me with the glorious flashing questionmark-folder-whatever logo. Just great.
I reset the PRAM (option + command + p + r), tried Safe Booting (shift + boot), tried forcing the laptop to boot into the default os x drive/partition (x + boot), tried booting with GUI boot location selector (option + boot) and, when all mentioned practices failed, inserted a retail copy of snow leopard and booted the machine to the ODD.
Disk Utility confirmed my fears: the main HD has no partitions and the "First Aid" tab can't verify or repair the disk.
Help me out here, guys. Is my drive dead (and all my data gone)? Is this a "directory collapse"-style issue? I had one of those babies a month ago on an '07 white MacBook... a new HDD and two hours of data restoration work for $150 at a local Mac-centric repair shop fixed that issue. But this seems a little more serious.
I was two days away from activating a central Time Machine backup to the home-network-attached 2TB HDD, for both Mac laptops in the household. I was also two days away from getting a Crashplan.com family package (yes, I wanted double backup). Why 2 days from now? Because my Carbon Copy Cloned backup HD (a WD elements 1TB) died a week ago. As in, "started-puffing-out-smoke" died.
Perfect timing.
Ideas? Please?
<Edited by Host>

I also suspect your internal HD has crashed. You can run Apple Hardware Test and then Google any error codes however I believe it's probably gone.
Without any backup yes your data is probably gone, there are data recovery services however they are extremely expensive.
If you purchased AppleCare you can take it an AASP for repair however they probably cannot do a thing about your data. If you are not covered by AppleCare of course the expense will be your however look at this as an opportunity to upgrade the internal HD to something with more storage or is faster.
Once you have the new HD installed you will need the original Snow Leopard Install Disks (or possibly your retail copy of SL) to format the new HD and re-install SL and the iLife applications.

Good luck,

Magsafe/MBP charging issue

My MBP 17" stopped charging. The MBP was running and either I didn't notice the power supply wasn't powering or it failed and let the laptop run completely down. When I tried to power back up I found the power supply wasn't working. Assuming it was bad, I purchased a new Magsafe (85W). It has the newer connector. It didn't work either. So in the course of monkeying around I removed the battery. The green led on the connector lit up. So it seems that now anytime the MBP has been shut off, to get it to chargethe battery or power the computer, i have to remove the battery. I can put it back in and everything is fine until the next go round. I've tried troubleshooting steps like making sure pins on the magsafe aren't stuck and the SMC reset. PRAM too. Anything else to try? And if not is this an issue with the magsafe, the battery or the laptop? FWIW, the old magsafe is still dead although I don't have another computer to try it on. Thanks.

The first thing to try is an SMC reset. Info and instructions here:

How I got my MBP heat issue resolved...

Like many MBP users, I too was having heat related issues. I decided to change a few things to see if they actually worked.
1. When I don't need the full power of the processors, I change my power source in the battery menu to "Better Energy Savings".
2. I don't run as many dashboard apps and when I find one, I make sure it is an Intel native binary.
3. I updated the SMC firmware on my Mac.
All three of these chanages have dramatically changed how my MacBook Pro works. I can now place it on my lap without any issue whatsoever.
I hope this works for you too.
MacBook Pro Mac OS X (10.4.6)

Thats a great idea,
why do purchased the MPB, if you reduce the power rating?
Under this conditions the MPB is now slower as the good old one.

STILL have MBP audio issues after Bootcamp 3.1

I have a mid-2009 MBP 13" with Snow Leopard, running 32-bit XP Professional with SP3. I just updated to Bootcamp 3.1 after dealing with low audio, robo-voice from the internal microphone, and spooky red light/trackpad nonsense for months. While 3.1 fixed the red light and the trackpad, my audio issues still remain; I get very poor volume on the Windows side and my voice is still distorted, slow and generally crappy when I use the built-in microphone in the microphone test. The mic doesn't work at all in Steam, which is the whole reason I want it. Was 3.1 supposed to fix these audio issues? It doesn't explicitly say so on the download page, but it seems like it's been quite effective for other people, so if it is supposed to fix the audio I suppose I'm going down to the Apple Store.
If 3.1 wasn't a magic bullet, can anyone suggest a fix? I'm pretty fed up by now with this issue. I tried reinstalling the drivers after extracting them from the BC 2.2 update (found that process on these forums), and it did nothing. The link to the New Jersey school's site (another suggestion from the forums) no longer works for whatever reason.
Thanks!

Use Driver Sweeper and the tips on how to use and troubleshoot
http://www.guru3d.com/category/driversweeper/
You may also want to use Windows Installer Cleanup as I mentioned.
Also CCleaner can help.
MSCONFIG.exe can lead you to the services and startup items being loaded
Programs control panel of course to uninstall the program
Device Manager to rollback; or uninstall and manage device drivers
Apple installs a number of drivers, services, startupitems so you really have to get familiar with the OS and where/how to manage things.
Windows 7 supports RESTORE POINTS. Use 'em! and set one before just in case (any good installer or update should create a new one but good to have your own), and make sure there is 10-30GB of space for restore points.
System control panel advanced protection -> configure your boot volume settings
