mavericks fan runs MacBook Air

not here, nope

check your APPS running.

FIRST TIME after install, Mavericks is doing a LOT OF THINGS......... so, that should be normal until you reboot

Spotlight indexing will have a great effect on power until it finishes, which might not be for a couple of hours. Write back if the fan does not resume its normal behaviour after a sufficient amount of time has passed.

You can use the new Activity Monitor to determine a unitless "Energy Impact" value and to determine when Spotlight finishes.

I have a late 2010 Mac Book Air 13" and had the same anomaly and it continued after the spotlight finished. So I disconnected all externals (external DVI linked monitor, USB keyboard) and rebooted with extensions disabled (did full power off and then held down SHIFT key during startup). Also FWIW during the original installation process I noticed that one of my extensions (Flip4Mac) was deemed incompatible so Maverick removed it but it did not remove the start-up process in the preferences pane so I manually updated the Flip4Mac (start-up process and app); that may have had nothing to do with this but the reason I often do a start-up disabling extensions is to see if there are extension conflicts with upgrades.

Other installation steps I did just for the record:

- cloned original OS disk

- tested clone

- installed Maverick

- installed other stand-alone offers in Software update (iPhoto, iMovie updates etc)

- started and then quit all new software

- updated out of date 3rd party software (only Flip4Mac in my case)

- started and quit all the software I routinely use

- ran CleanMyMac2 to get rid of about 3GB of language files etc I did not need after install

- waited for spotlight to stop indexing [the fan was still running at this point]

- powered off and then rebooted with extensions disabled

- started fine (no fannoise)

- reconnected peripherals and did normal restart

- working fine now; curiously I have about 1GB more disk space than I originally had too ... I guess the system is lighter ... BTW I have PERMANENTLY archived my old clone and will now clone my new system onto a fresh drive while I get my coffee for the work day ahead.

- total time for above was just under 3 hours

You are using a third party product to control the fan speed (smcfancontrol). Uninstall it and let your Mac work the way it's supposed to work.

You also installed MacKeeper. Get rid of it by following these instructions exactly as written:

• If you used MacKeeper to encrypt any files or folders, use MacKeeper to un-encrypt them.
• Quit the MacKeeper app if it is running.
• Open your Applications folder: Using the Finder's Go menu, select Applications.
• Drag the MacKeeper icon from your Applications folder (not the Dock) to the Trash.

You will be asked to authenticate (twice):

You do not need to provide a reason for uninstalling it

Click the Uninstall MacKeeper button. You will be asked to authenticate again.

After it uninstalls you may empty the Trash and restart your Mac. All that will remain is an inert log file that does nothing but occupy space on your hard disk.

Next: Test your Mac for operation. If it is still exhibiting problems, you may need to undo damage that occurred as a result of using MacKeeper. At the extreme this could include erasing your Mac and rebuilding your system from the ground up.

You will be back with other problems as a result of that action. It may be days, weeks or months before they become evident. Please start a new Discussion when they do. Thanks.

Thanks John. I haven't had any problems yet doing this over the years - I manually do most of my cleans with CleanMyMac# and keep a tight control on it; I'll open a discussion if I run into issues though. Thanks. BTW I'm also >28 years Apple - started wih Apple II and then Lisa ... 🙂

I have exactly the same issue. no 3rd party software installed. Fans are kicking in at around 60° already. Issue still the same after SMC and PRAM reset.

I opened up ActivityMonitor and found a few Safari QT processes not responding. Force Quit those and the fans were back to normal. Check in Safari for plugin updates or try to reproduce without having them enabled...

I had a similar issue. Installed Mavericks last night and this morning at work noticed the fan was continually runnng and the MB Air was hot. Opened activity monitor and discovered Outlook was using 51% of CPU (and was non-responsive). Force Quit Outlook and in a couple minutes fan was off.

Ohh, my goodness 😁

15.68 HOURS on a 2013 Macbook Air 13" "****faints***"

Same issue here on my 2013 MBA "13 after upgrading to 10.9.

Same Issue on MacBook mid 2011, and the Mail App, is taking almost 2GB of Memory in the Activity Monitor and Kernel task taking 380MB. Somebody now why that's?

is taking almost 2GB of Memory.......Somebody now why that's?

Mavericks is designed to use RAM differently for good reason. Normal 😉

http://appleinsider.com/articles/13/06/12/compressed-memory-in-os-x-109-maverick s-aims-to-free-ram-extend-battery-life

Mavericks uses RAM much more efficiently than any other previous version of OS X. Mavericks now has a memory compression feature that will compress the memory occupied by applications that aren't being actively used and give the freed up RAM to the application that needs it the most.

Memory Pressure graph that tells you how stressed is the system in terms of memory.
