When i check the istat all the memory appears there however i cant figure out what inactive memory is? 
  • Wired memory — This is memory that applications or the system needs immediate access to, so it can’t be cached to disk. It will vary depending on what applications you’re using.
  • Active memory — This is memory that is actively being used.
  • Inactive memory — This memory is no longer being used and has been cached to disk. It’ll remain in RAM until another application needs the space.
  • Free memory — This memory is not being used.
