Fan is loud and won't stop making noise

Help please

Hi m,
That is likely because your MBP is getting hot and the fans need to cool it down. Try an SMC Reset: http://support.apple.com/kb/HT3964
If that doesn't resolve things, install iStat Pro and you can get temp readings and fan speeds to report here.

My macbook pro won't stop making noise! It sounds like the fan but I'm not sure. Any ideas?

my macbook pro won't stop making noise! It sounds like the fan but I'm not sure. Any ideas? It's really worrying me because I haven't had it for up tp 2months and last week everytime I switch it on it makes sooo much noise. And I treat like an egg so I don't understand whats going on.

Hey,
My friend had a very similar issue to yours. The issue came down to the pins of the MagSafe not meeting with the MacBook perfectly causing the lights and the transfer of power to be wacko. I'm not sure if this is issue that your experiencing, but its worth checking out the pins and the MagSafe area on your MacBook for debris.

If that is all clear, then I would suggest you call AppleCare or take it in to an Apple Store to have it checked out.

My Time Machine keeps backing up and won't stop.

My Time Machine keeps backing up and won't stop. The problem started when it said I was out if space. It is supposed to delete the oldest backup. Now I cannot even backup at all. It just keep going and never stops, although it really does not work at all. I have used the disk utilities and iI have Zeroed out. The TC is a 1 TB and is about 13 months old. Right now it says "79.9 MB of 104.9 MB" and "backing up 961,837 items". I do not have the check mark in "Notify after old backups are deleted." It will stay stuck like this for hours and hours. The TC is plugged into a U-verse router and the 27" MAC is plugged into the TC.

So you already wiped the old backup and started again??
If that is the case it did a fresh full backup ok?
How much free space is on the TC now?
Do you happen to have multiple network links? Meaning do you have TC bridged to the U-verse router.. with both ethernet and wireless working at the same time. I discovered this one all by my loansome.. having multiple paths does not seem to worry most things on the computer.. but it totally kills TM.
I had the same sort of thing happening in testing a TC I am fixing. So I have multiple ethernet and wireless. The incremental backups became extremely slow.. by turning off wireless and one ethernet so there is only one route to the TC.. it flys again.

Welcome to the Apple Support Communities
I have seen a lot of cases like your issue, and it's easy to solve.
First, open Disk Utility, select Macintosh HD in the sidebar and repair permissions. Sometimes, a permission can be damaged and it makes that an application doesn't work properly.
If that doesn't work, open Finder, select Go menu > Go to Folder, type ~/Library/Prefereces, delete "com.apple.desktop.plist" and "com.apple.systempreferences.plist" and restart

HT201656 Email is unusable as it keeps trying to load emails and won't stop. What can I do?

Email is unusable as it keeps trying to load emails and won't stop. What can I do?

Try closing the mail app completely and reboot your iPad. Assuming that you are running iOS 7 .....
Double tap the home button and you will see apps lined up going left to right across the screen. Swipe to get to the Mail app and then swipe "up" on the app preview thumbnail to close it.
Reboot the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider if it appears on the screen - let go of the buttons. Let the iPad start up.

My fan makes loud and very strange noises.

Hi again,
My fan makes loud and very strange noises. Is there any cure for that?
Thank you!
Markus

Hmm... that is strange. There are a couple reasons that I can think of.
First, go to System Preferences -> Energy Saver -> Processor Performance. See what its set to. If it is currently set to Highest, your fan could be going more often. Turn it down to Reduced or Automatic. Note if there is any difference.
Secondly, are you all up to date on software updates? The last step was to see if it was a software issue. If it isn't, then you probably have a defective fan. AppleCare?
Now, you would open your PowerBook. Look in the Apple docs (Support - Manuals) to find how to do it for yourself, or take it to a shop or Apple Store and have them do it. Safest option.
Look at your fan. Has it come free of the anchor and is hitting against the wall or fan surround?
Lastly, try keeping the PowerBook in a open, ventilated area. The fan will power up less if the computer stays cooler. For a possibly irritating but possibly helpful option, purchase a product that lifts the PowerBook off your lap or desk. I think Rain Design makes a good one.
Good luck!

15" MacBook Pro runs hot, fan is loud, and incredibly low battery life

My 15" MBP was bought in March or April (can't remember) from Singapore Apple Store. Here are the stats:
MacBook Pro 15-Inch, Late 2011
Memory 8 GB 12222 MHz DDR3
Software Mac OS X Lion 10.7.5 (11G63)
Also I'm using about 1/2 of the available 750 GB of storage.
Here's what's up:
1. The fans boot immediately after the computer is turned on and never stop, making everything much too loud...like a plane is taking off or something.
2. The computer is WAY too hot. Right now I'm running Astrill, Chrome, Activity Monitor, and System Utility, and when I put my hands on the thing it feels like my fingers are going to melt.
3. The battery life, even at a full charge, is about an hour overall, which ***** for so, so many reasons.
Here's what I've tried:
1. I took it to the Shanghai Genius Bar, but I think that the language barrier is impeding my ability to really say what's wrong. I backed up, and they wiped the hard drive, re-loaded the OS and put all my old stuff back on the computer. They also deleted SOMETHING from the Preferences part of the library, but I don't know what it was. Everything runs much faster now, but the fan, the heat, and the battery are still having their issues.
2. I've checked the "all processes" CPU usage. There's nothing unusual (as far as I can tell), so I'm at a serious loss as to say why the computer is running so hard. Even with all the processing running as you see below, the fan's still blasting and I've lost 50% battery life in the past 40 minutes.
3. I've tried the fix that requires deleting com.apple.desktop.plist and com.apple.desktop.plist.lockfile. It changed the way the desktop looked and absolutely nothing else.
PLEASE, PLEASE, PLEASE help me! I'm a graphic designer and often run the CS6 Suite. (Currently, however, I am NOT running any Adobe programs and I'm still experiencing the problems.) It's really important that I am able to run Photoshop, Illustrator, and InDesign at once, and it CAN, but with the heat problems I'm having without ANY of the graphics stuff running, it worries me.

Just took another look at iStat Menus (I've only had it for a couple of days - I used to use the old iStat Pro widget) and it seems as if you can make fan speed defaults and use them instead of relying on your MBPs sensors to take care of the fans... see...
Might want to use that 'medium' speed (there by default as I know I didn't add it) and keep an eye on your temps. If you start heating up to much, go back to the 'Default'.

After browsing websites, the fans get louder and louder, no internet.

Hi,
With my 2011 Macbook Pro 15inch, I have found that browsing some websites causes the fans to spin up very loud and the internet to drop.
Websites won't load etc. Even after reconnecting to my wireless network. The only thing that seems to fix it is rebooting.
Sometimes this will happen quickly, other times it may take an hour of browsing before the internet stops working and the tell-tale sign of the loud fans
makes an appearance.
All other features of the laptop work, just not the internet. Across all browsers too.
Thanks in advance,
Finn

The only way to know what is going on is to retrieve the certificate and check who is the issuer.<br />
It is always possible that the server doesn't send the full certificate chain (intermediate certificates), so it might help to post a link to this website
Check the date and time in the clock on your computer: (double) click the clock icon on the Windows Taskbar.
Check out why the site is untrusted and click "Technical Details to expand this section.<br>If the certificate is not trusted because no issuer chain was provided (sec_error_unknown_issuer) then see if you can install this intermediate certificate from another source.
You can retrieve the certificate and check details like who issued certificates and expiration dates of certificates.
*Click the link at the bottom of the error page: "I Understand the Risks"
Let Firefox retrieve the certificate: "Add Exception" -> "Get Certificate".
*Click the "View..." button and inspect the certificate and check who is the issuer of the certificate.
You can see more Details like intermediate certificates that are used in the Details pane.
If "I Understand the Risks" is missing then this page may be opened in an (i)frame and in that case try the right-click context menu and use "This Frame: Open Frame in New Tab".
*Note that some firewalls monitor (secure) connections and that programs like Sendori or FiddlerRoot can intercept connections and send their own certificate instead of the website's certificate.
*Note that it is not recommended to add a permanent exception in cases like this, so only use it to inspect the certificate.

Mac mini Intel Core Duo fan very loud and runs at high speed all the time.

I purchased an "Open box" Mac mini Intel Core Duo, 1.66Ghz, 2G ram, 80G HD and SD a few days ago from Fry's.
It runs beautifully except the fan is very loud compared to any Mac my family has ever had. It is so loud that we were thinking of putting it under the desk.
The fan runs constantly, and I mean all the time, at a high speed. You can really feel the air coming out the exhaust vents. The case is always cool to the touch as is the exhaust air.
My aunt bought a similar Mac mini (But only 512Mb ram) the same day. Her's is very quiet. The case feels just slightly warm, not unlike other Mac mini's I've seen.
Should my Mac mini's fan be running this way?
Thanks,
llulua
BTW: The "open box" was sealed with a Fry's label and it said that this had a new warranty. Yet, checking the serial number, it said that it had about 260 days left. I guess Fry's is backing it?
Also, someone told me that perhaps the main wire from the fan to the logic board is disconnected.

Since you have 2 gigs of memory, my thoughts are that when the party (Fry's or the origianl purchaser) upgraded the memory, they neglected to reattach the wire at the front of the Mini under the IR receptor at the right front corner that regulates the fan speed. This wire must be unattached in order to upgrade the memory, and is probably why the original person brought it back, because of the fan noise resulting from failing to reattach the wire. If that wire is left unattached, the fan runs continually at high speed to protect the CPU and system in general. If you do not want to use a putty knife to open the Mini, take it back to Fry's and ask someone who is Mac savvy to open it and reattach the small plastic receptacle at the end of the wire into its socket at the right front of the machine. When I go to Fry's, I am always concerned because the employees allow people to pry keys off of the Apple notebooks, so don't expect that their employees to know or care about anything Mac.

Why are my fans so loud and my macbook pro so hot?

I have a 15" MacBook Pro. I've had it since a little bit before Christmas and the fan has always been so loud and the laptop itself, as well as the charger, tend to get VERY hot VERY quickly. I'm keeping it elevated so it's not being suffocated but it doesn't seem to help. I've already checked Activity Monitor and nothing is running up my CPU very much and I'm out of options. Any help is appreciated!! It's driving me crazy!!

Those are very, very high temperatures and very high fan speeds just trying to cool things down.
Now - which applications or processes are turning up the heat? Open Activity Monitor (Applications>Utilities) and select "All Processes" and sort by CPU %:
Then post your screenshot (http://support.apple.com/kb/PH4391) using the little camera icon in the composition bar at the top of your reply.

Will running games that make the fan run loudly and the computer heat up damage my machine?

On my Macbook Air running Yosemite 10.10.3, with 4 GB RAM, 251 GB storage (170 GB free), a 1.6 GHz Intel Core i5 processor, and Intel HD 6000 1536 MB graphics card, when I play games such as Batman Arkham City, I experience very smooth gameplay with high fps. The only thing that worries me is when I play, the laptop heats up very much and the fan runs pretty loudly. Even with old, less intensive games like GTA SA, the computer gets pretty hot and the fan runs loudly. Is this damaging the computer, or can I continue to play these games?
Thanks.

Yes you can continue to play games but heat is the bane of electronics and in time there will be a cost. When is hard to say, but I can put it this way, a fan running constantly at high speed is more likely to fail sooner than one at a slower speed.
Ciao.
