• problem of fan with sierra?

  Hello

  Everyone knows their MacBook Pro fans go into overdrive without provocation since the upgrade to Sierra?

  I don't have that mail and Safari open (to make this post) and fans are whirring away as I use a 3D graphics heavy program.

  The room is cool and the MacBook is raised on blocks to facilitate the movement of air, but its always acting like there is more of the work in progress.

  It doesn't seem fair.

• iMac 27 "mid-2011 - Intermittent problem with CPU fan running at full speed and sleep mode.

  Hello!

  My iMac 27 "has an intermittent problem with the CPU fan runs at full speed. Sometimes it happens at the time when I start it, sometimes only in my session, and sometimes only after a certain time. So does seem to be a problem of "heating".

  Second issue is with the mode 'sleep'. It may occur also at any time, at the start of the iMac, session, or after a certain time. But once he starts to go in mode 'sleep', when I wake up, it goes right back in mode after a few seconds and that it will continue indefinitely until I restart the computer.

  What could be?

  Please help me!

• App, networking, process cloud runaways; Very slow to connect to servers, high fan

  I have the same problem on two different computers. A new installation (of Sierra of MacOS) (with costs users, no restored settings, preferences, etc.) fixed, but not the other. (Past the wire: all Web apps suddenly slow; fan high speed).

  On the computer that still does not, have the following processes often rampant and prevents the computer access to the servers to load pages, apps, etc..

  • trustd
  • Mail
  • messaging networks
  • Safari
  • Networking of Safari
  • storeaccountd
  • AKD
  • accountsd
  • nsurlstoraged
  • nsurlsessiond
  • syncdefsultsd
  • cloudd
  • com.apple.CommerceKit.transactionservice

  Obviously the issue transcends the user the user and settings (because it affects the settings and new users).

  So I guess that it is a problem with iCloud? A question of trousseau (iCloud)? How to fix this?

  I am VERY interested in any orientation.

  I just tried these steps recommended for new users of macOS with wifi problems: http://osxdaily.com/2016/09/22/fix-wi-fi-problems-macos-sierra/

  The problem persists.

• The operation of the fan of excessive causing Sierra

  After the installation of Sierra 10.12 the fan on one of my MacBook pro is running excessively. Activity monitor shows a process 'DCs' as a means of 93% of the CPU.  Tried to use force quit and it comes right off.  On my other MacBook, the activity monitor shows the 'DCs' as 0% CPU and there is no problem of fan.

  This process is linked to the keychain.  You have the ring of the value be synchronized via iCloud in the system/iCloud preferences window? If so, uncheck, restart and check the DCs again process in activity monitor.

  If the activity has returned to zero, activate it again (if you want to sync on devices) and check again the activity monitor.

• The fan runs all the time because xinetd running more than 80% all the time.  Someone else has the same problem?

  xinetd is running at 83% or more 24 x 7 devours battery in 2 hours or less and making the fan run all the time.  I am connected to a bug report, and it turns out that it was a duplicate because someone else had the same problem.  However, I have no access to the other bug report or find anything either in the discussion forums or online.  Anyone experience this problem?

  Hello gorgonzola1111,

  I doubt that someone else has this problem because xinetd does not part of macOS. Have you installed it from a package of "ports" 3rd party?

• Fans of fast and slow mail after upgrade of Sierra

  So I too just upgraded to Sierra, and I have two problems.  The first I noticed almost immediately after a reboot is something is causing fans to run almost non-stop.  I looked at the level of the console and I see that several root applications use more than 100% of the time CPU.  What the hell is happening here?

  Second, Mail has now slowed down to the point that it is almost unusable.  I click on an email and it will literally be anywhere from 15 to 20 seconds for the mail to open.  Not a complex HTML with email of old thing plain video simple.  What the hell is happening here?  It's maddening.

• The fan works like a crazy and super fast drain battery after installation of Sierra

  I installed Sierra on my MacBook Pro, the fan works like crazy and the battery is empty after about 1.5 hours. Which never happened before. I'm only using Safari and Mail in the moment. I talked to Apple Support and they suggested to reset the SMC, but this brought no improvements. What can I do else? Again, I plan to install the El captain...

  I had this problem just after I installed Sierra on my MacBook Air.  First I tried to reset the SMC and the LANDAU.  This does not prevent fans constantly in the course of execution.  I then used the activity monitor to see what was possibly strain my system.  I noticed the "DCs" process was always sucking up to more than 90% of my CPU usage.  However, others said that it is normal after an upgrade of the OS and it should fall back down once the computer finishes its initial picture and analysis of the files.  So I run my MBA plugged nonstop for 36 hours in a row and the fans just kept running so that the process of "DCs" continued to drain at > 90% of CPU usage.  I also looked carefully at the activity monitor and saw that tasks such as analysis of photos had their own separate process "DCs".  So I dug further into what the devil "DCs" was really do with a lot of CPU resources.  Long story short, I found that there is some glitch in Sierra which causes the macOS stuck on a process involving the keychain and iCloud.

  That's what I did to fix this keychain/iCloud which led to "DCs" fans of triggering and overloading the CPU to be always on:

  -In the activity monitor, I used Force Quit to kill the process that involved the keychain

  -In the activity monitor, I then Force Quit the process that involved icloud

  -In activity monitor, I finally Force closed the process "DCs". (I found that I could not simply force quit 'DCs' without first allowing the keychain & iCloud first)

  -After all, I restarted the computer and fans were finally off the coast!  I open the activity monitor and saw that 'DCs' has is no longer hogging up the CPU usage.  Photoanalysis process were still running in the background at 40-50% CPU use with no trigger unwanted system fans.  the iCloud synchronization and my keychain also worked very well.

  I'm finally able to use Sierra without my fans blazing out of control.  It took me a while to get this sorted out.  Hope this helps to save you a few headaches and time until Apple can get counts that there is this Sierra software glitch they need to address.

• Fan works like crazy and the battery drains quickly after the installation of Sierra on MacBook Pro

• Fan runs almost always since the installation of Sierra and MacBook Air running Mac OS.

  Hello

  Since upgrading to Mac OS Sierra last night on my MacBook Air (2013, i7, 8gbRAM), fans work almost always, even when I use Safari.  Previously, the fans would go only when I was playing a game, or video edition.  The basis of my Macbook Air is also much more hot he was under El Capitan - once again, just when you use Safari.  As a result, my battery life is horrible - dropped from 100% to 23% in a little over an hour.  Once again, under El Capitan, if I was just using internet, use of an hour would see the maximum of 10 to 15% of decline in battery.

  I turned off my Macbook Air and it turned on again after fifteen minutes, but in 10-15 minutes, fans revived upward and the base (and the top of the keyboard) heated again.  No uncomfortable levels, but certainly noticeable levels.

  Just to remind - I use Safari only when this happens.  Moreover, since the beginning of this question five minutes ago, the % of battery has dropped from 29 percent to 22 percent and the fans are still whirring like the dickens.

  No idea why this is happening?

• Fan number after updating to Mac OS Sierra

  Hello people, as many of you all know, Apple released macOS Sierra. The updating of this new operating system, I have been met through rather annoying problem for me. It seems that my fan is not eager to be quiet as it has been in the previous operating system. The computer is usually warmer than its normal temperature. At first I thought it was a software problem during the upgrade. I came back to El Capitan, the computer runs cool. Fresh installed copay of Sierra and the computer becomes extremely hot and fan running constantly at high SPEED. It's quite strange to me, so I was wondering if someone else running Sierra also have this problem. I have little friends of mine Sierra both running on their MacBook Air machines, but they have the same problem. Any help or suggestion? Thank you

  Hi SC909,

  It seems that your computer is running more hot than usual, and as such, the fan is at the top all the time. I would say that resetting the SMC on your computer:

• Mac Mini (mid-2010) fan running full speed

  I went on the hard drive of a few years for one SSD OEM and the fan runs all the time.  In my view, there is a connector on the card, which has no connection with it.

  I read that this occurs when the thermal sensor is not placed on the new hard drive.

  How many connection should be here soon out of the drive to connect to the map?

  How can I fix?

  TIA

  The original HD had a sensor taped to the road with adhesive tape double faces. You had to move the sensor to the new drive. Without the detector, the fan runs at full speed.

  What ha [[ERA of the sensor on your Mac?

• I have a my I plugged Mac when I turn again the fan is now blowing air all the time

  I un plugged my I Mac when turns again the fan is now blowing air without stop

  
  

  It is a signal that there is a problem on the boot volume. The system to do a routine check and you start in single user mode (SUM), the fan starts after a period of 3 minutes in SHORT (?) to ensure that the equipment will not become to be hot. This happens because BASICALLY the system do not have information on the internal temperature of the system; It is administered by the system which works in start normal mod.

• Fan Controll Macbook Air mid 2009

  How can Hi I adjust the fans to market at a lower temperature Macbook Air mid-2009.

  I know that video playback makes the hot computer. I'd like set the fans to turn on at a temperature lower, without having to download a few app controll or software.

  Be well theres a way.

  Thank you

  Marta

  No, sorry. The fan profile is pre-programmed and are not adjustable in OS X user. The only option would be to reset the system management controller, but which was designed to solve the fans 'stuck' at great speed among other things.
