Hi guys, after upgrading to OSX El Capitan my MacBook Pro i7 became very slow. I am aware that the early version of OSX El Capitan's has umpteen bugs in it, especially the Mail's log thingy. I tried to open Activity Monitor and was truly gobsmacked that my RAM was fully used! It was this process name called 'AppNIB' which threw the monkey wrench on my mac. I had to execute the kill command in Terminal in order to kill that process because I don't have the faintest idea what app is it. Can anyone elucidate to me, what does this AppNIB do? Thanks in advance!
