My name is***** am sorry to hear that you are having this issue.
I will be glad to assist you with this.
What is the version of Mac software on the 13 inch MacBook?
click on the Apple icon in the top left corner of your screen. From there, you can click 'About this Mac'.
You'll now see a window in the middle of your screen with information about the Mac you're using. ie.. OSX Yosemite, ElCapitan, etc...
