  1. What are the cons and pros. Also will we be able to switch back to the old
    operating system by ?

    • Pros : Siri on Mac and a few productivity features. Cons : it’s beta 1,
      therefore you might find some bugs.

    • You can backup the entire installation of the old OS using something like
      CCCloner to an external hard disk, and then format and copy that back to
      the Mac once you are done using Sierra

  2. There is a method for use macOS Sierra from the USB without installing on
    the mac?
    Please answer, thanks

  3. Great video Jeff, will this work if you have a mac which is not supported
    on this new software (my early 2009p imac is not supported in this update),
    could this be a way around this block off?
