MacBook running hot after installing OSX Lion – Fix here

After installing OSX Mountain Lion I noticed that my Mac Book Pro was getting extremely hot and battery life was poor at best. Seems I was not alone.

After googling (if that’s a verb), I discovered one of several solutions:

  1. You’ve got a Citrix type client installed which is running in the background (see this thread)
  2. You have Office 2008 or 2011 and Spotlight is having an issue with indexing (see this thread)
  3. You need to reset your SMC (see this Apple KB item) – this is not as likely as the others.

I have gone through all three and so far it seems to have cooled the laptop. I’ve also noticed that Flash/Shockwave sometimes hangs with high CPU – with the new changes I need to evaluate if that’s still a problem, but figured in the meantime I’d share how to potentially fix your Lion woes.

Update 1: After performing steps 1-3 I noticed improvement in battery life – until I started to use Chrome with a site using Flash and suddenly Shockwave was going crazy with CPU and memory usage. Again, it’s not just me. If anyone has ideas please comment below.
