Training video 3 -Part 1 Query on code

I copied code shared in Training Video 3 and configured externel JAR's as shared by you in my MAC. But i see error's in the import statement and other statements as well as shown in the screenshot. Am i missing anything? Can you please help me on this.

If we are using MAC laptop for configuring appium can we start from Module 1 or need to first complete Training video 12 and 13 which are specific to MAC?

Error import statements:
