Q: Fast fans and slow mail after Sierra upgrade

So I too just upgraded to Sierra and I have two problems.  The first which I noticed almost immediately upon reboot is something is causing the fans to run almost non-stop.  I have looked at the console and I can see that several root apps are using over 100% of the CPU time.  What the heck is going on here????

Secondly Mail has now slowed to point that it is almost unusable.  I click on an email and it literally will take anywhere from 15-20 seconds for the mail to open.  Not some complex HTML with video thing just simple plain old email.  What on earth is going on here?  This is maddening.

    Verify your location in System Preferences > Date & Time.

    Verify System Preferences > Security & Privacy that location services is checked.

      Click on Location Services.

      Select System Services (bottom of list)

    Still having issues with GpSoverWiFi.....

     

    Verify your DNS settings

    Open System Preferences > Network > Wi-Fi

    Write down the settings under Advanced > DNS tab.

     

    Turn off Wi-Fi. Log into a new User and add Wi-Fi. Compare the settings under Advanced > DNS tab.

    Make any necessary changes in your User. You might need to remove then add back.

     

    Use Namebench to find the fastest domain name servers.

     

    Download and run:  Namebench (free) http://code.google.com/p/namebench/

     

    Once you have the fastest domain name servers, you then have to manually change your DNS settings in System Preferences/Network/

     

    BTW, Google server settings are- 8.8.8.8

    Another option is to try turning off IPv6:

     

    In System Preferences --> Network -> choose the Ethernet tab in the far left column --> Advanced button -> TCP/IP tab --> Configure IPv6: dropdown menu, choose Off --> Okay button.

     

    Hope this helps!

    It kept on bothering me that I couldn't get sierra to work correctly so I went to the Apple Store and looked at the activity  monitors on at least the MacBook pros and one MacBook all were running normally. I asked a apple employee do they   just upgrade or clean install. CLEAN INSTALL whenever a new OS comes out. Sierra is the catalyst for a new filing system that's going to be the norm soon. So why not prepare for that. I know a clean install might not be best for everyone but a day of install and retweaking vs a surprise glitch in the middle of something important is a no brainer for me. I backed up 2 1/2 gigs of stuff which most was junk. Erased, Clean installed Capitan and immediately Sierra. Then all the important apps Lightroom, Photoshop plus other top apps and with iCloud very little tweaking is needed. I went in safari before the install and took pics of the passwords in email addresses just in case. BUT NOW SHE WORKS FLAWLESSLY no Heat, Fan or mail issues. Save some on iCloud and start Time Machine Over.

    Many thanks I did have to do this previously for El Capitan.  However, It is a real pain to do this when you have everything already set up to work correctly.  Yes I can already hear the folks saying well what do you want a machine that works or one that has your stuff but is constantly trying to melt down.  Sigh, what is wrong with wanting things to just work?  That is the way the Mac started out....

    Mac users got what they wanted, more features in smaller boxes, so it got more complex. You don't really want to regress 25 years do you?
