#  Thomas Eeles. 
#  macOS Health Check (M.H.C)
#  Script for helpdesk and end users to track details of their device. 
#  The scipt lets users see if there macBook is ready to be replaced. 
#    - To Do: Add logging to /var/logs, add in function for Button Two, cheange the variables about, add in checks for SwiftDialog.
