Dad mucks about with our Mac and makes a TV show (9)
I believe the answer is:
docudrama
'show' is the definition.
(I know that docudrama is a type of film)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for docudrama that I've seen before include "TV play based on real events" , "sort of play" , "realistic fiction" , "Dramatised TV programme based on real events" .)
