Macbook pro retina start to make loud fan noise and work slow

I bought macbook pro retina display less than one years ago. For some reason my macbook pro has been making loud fan noise for about five mounth. Whenever macbook pro makes the noise, all the programs start to run slow. Typing, opening safari, and etc takes forever. It takes 20min to 40min for the noise to stop. At first, the macbook pro made noise once or twice in a day, but now it's making the noise frequently; It happens every 2-3 hours. It got to the point where it start to annoying me. Is there a way for me to fix this issue? If not, can I use one year warrenty to fix this problem? Thank you.

If your Mac works slowly when fans turn on, it's quite possible that there's a process which is eating the CPU and/or RAM.
Open Activity Monitor (in /Applications/Utilities), select "All Processes" above "Show" (in the toolbar) and then, order the processes by CPU usage. Do you see any process which is consuming more CPU or RAM? If so, tell us the name.
Additionally, you can reset the SMC > http://support.apple.com/kb/HT3964

Mac is making a whirring sound and screen is blank

My 2008 desktop Mac started making a loud whirring sound in the middle of the right when it was left on. It was turned off at the wall switch and when turned on in the morning, it started reving up with the same whirring sound and the screen was blank. After on for a few minutes, a file folder icon appeared in the middle of the screen with a large question mark in it. Mashing some buttons on the keyboard did nothing. Had just upgraded to Snow Leopard. Any suggestions?

Powerbook making clicking sound and running slow

I have had my powerbook for 3 years. Just recently it started running very slow and spinning beach ball comes up alot. There is a clicking sound coming from the top left corner of the keyboard by the speaker. When the clicking starts is when the beach ball comes up. It doesn't happen all the time. This occurs about every couple of minutes and then goes away. Once the clicking noise goes away the computer runs fine. I have ran disk utility, onyx and techtools (no errors have come up). Nothing has seemed to fix the problem. Can anyone give me some advice on what might be the problem. Thanks for your help.

Welcome to the Apple discussions.
That sounds like a hard drive possibly beginning to fail. However, it's located on the left side under the palm rest. In the upper left corner of the keyboard, the only moving part is a fan, however, if that were doing something odd it shouldn't cause the beachball to come up, which leads me to think it's a hard drive issue. Next time you hear the ticking, see if it could be coming from under the left palm rest area.
So, ensure that your important data is backed up, and do it regularly, if not doing that already. Assuming it is your hard drive, you can either live with it, or replace the hard drive. (Don't know if you have Applecare, since you said your system is 3 years old). You may have a 4200rpm drive in there today, with 5400rpm being mainstream today, and 7200rpm the faster option. Sizes go up to 160GB in 5400rpm and 100GB in 7200rpm. Seagates come with a 5 year warranty versus 3 year for most other drives.
If you're handy, you can do the replacment yourself or an Apple Authorized Service Provider or Apple can do it. If Apple or AASP does the replacement, make sure they write on the service order that you want your old hard drive returned to you. Recently, there was a person who was surprised to find that Apple may retain the drive as a trade in on the replacement drive. Also, if it were me, I would specify I want a new drive and not a refurbished drive.

New Mac Mini making loud clicking sound

I bought my Mac Mini (Late 2012) in August 2013 and from the first week of having it, it periodically makes a loud 'click' noise followed by a series of 'tick tick tick' noises. This is usually accompanied by a slight hang in any .app I'm using and my iTunes will cut out momentarily. Sometimes it happens when I'm not doing anything on it at all.
Is the hard drive failing, and why on earth would that be an issues in a brand new computer? Am I going to have to take it in for repair, as it's my only computer for work?!

Dead on arrival hard drives are nothing new. Even my folks had a Dell with one. Transportation in an unpadded cases can also jar a hard drive, though usually the parked heads prevents any damage. You should always be backing up your data regardless:

At least you are under the 1 year hardware warranty. Buy AppleCare before that runs out, and that way you will be covered until 3 years from date of computer's purchase.

Anyone encounter loud fan sound upon power up?

Hi,
When I power up my iMac, I encountered a very loud fan sound in the background that I had never encountered before.
This happens despite turning off and powering up again.
Any idea what's happening? And how to remedy the situation?
Regards.

I would recommend downloading and running the popular, useful and FREE "iStat Pro" to see what the actual temperatures of your computer's inner components are. Then post the data here for us to see and comment. You'll find it here:

Hope this helps

Seagate FreeAgent Go is making a clicking sound and the light is rapidly blinking. My Macbook is no longer recognizing it. Is there any way to fix it or recover my files? The SeaAgent is less than a month old!

Seagate FreeAgent Go is making a clicking sound and the light is rapidly blinking. My Macbook is no longer recognizing it. Is there any way to pull all the songs I have saved on it? The SeaAgent is less than a month old!
Does anyone know how to fix this issue?
Or at least recover the lost data?
Thanks!

How to fix: the drive is in warranty, so contact Seagate for a replacement.
How to recover your data: Do you have backups? (If not, you really, really, should.)
You can try downloading Data Rescue, which will run in trial mode and let you know if the data is recoverable. (You can then choose to purchase the full version if it works for you.) A clicking drive, though, is usually (though not always) a sign that the drive cannot be recovered.

Loud popping sound and then nothing

Everything was working beautifully then suddenly I heard a loud popping sound and the screen went black and the computer was dead. I turned everything else off, waited about thirty seconds and tried to turn it on. When I press the on button it lights up but nothing else happens.
Any thoughts?

Hi, and a Warm Welcome to the Power Mac G5 Forum!
Well - a loud pop was the classic symptom of a blown Power Supply Unit.
Not sure which G5 you have... but if it's a "Late 2005" dual-core
http://support.apple.com/specs/powermac/PowerMac_G5_Late2005.html
then it should be fixed under this

If you have an earlier G5, please post again. Good Luck.

My ipod classic has started making a mewing sound and all it does is scroll through the songs. It will not play except when connected to my computer. I tried resyncing and that did not work. How do I fix this problem?

My ipod classic has started making a mewling sound and all it does is scroll through the songs. It does not play on my Bose sound dock or through earbuds. It will play when connected to the computer...but that makes it hard to take it on a walk with me I thought it might be a synching problem so tried that--still doesn't work. How do I fix this problem with out restoring it to the factory setting? I do not want to lose all my music content as some of it I cannot replace easily. Please help with suggestions and advice. Thanks. Karen in GA

HT1338 HOW CAN I SPEED UP MY MAC IT HAS A GRINDING SOUND AND THE COLOUR WHEEL SPIN AND FREEZES

MY IMAC HAS A GRINDING SOUND AND ITS SLOW, THE WHEEL START SPIINING AND IT FREEZES I HAVE TO TURN IT OFF AND ON AGAIN , WHAT IS THE PROBLEM AND HOW CAN I SPEED IT UP AND GET IT TO RUN FASTER?

Does the sound appear to be from the hard drive, such as when you do any work (which means the hard drive is being written to)?
Have you received an email from Apple about their Seagate hard drive recall (for certain iMac models)? Check to see if yours is affected here:
http://www.apple.com/support/imac-harddrive/
In any case, a grinding noise is what I had, followed by other very strange behavior and the diagnosis was hard drive failure. So, whether you are covered or not, I would strongly suggest that you backup all your data as quickly as you can and - if you're not covered by warranty or the recall - book an appointment at your nearest Genius Bar for a diagnosis.
Also, please do not use all caps - difficult to read and it's considering shouting on the internet.
