Samba causing High CPU Usage in kernel_task - Temporary Fixes

[WiZMaC]

Hi everyone,

 

Out of the blue, the samba ( windows file sharing ) daemon started acting funny causing high cpu usage in kernel_task and the current temporary fixes include:

 

1. Fix originally posted by GiantRobot on ArsTechnica - Edit /etc/smb.conf to make sure your machine never becomes a master browser except when it is really the only machine on the network. To do that add:

 

domain master = no
local master = no
preferred master = no
os level = 0

 

Make sure to restart samba after that.

 

2. Goto System Preferences --> Sharing --> Windows Sharing : Stop/Start (Uncheck/Check)

 

This has been plaguing both OSX Intel & Mac users.
