The 20-year-old goalkeeper, who was with Leeds United as a youngster, gave up full-time football to concentrate on his studies.
With those now complete, MacGillivray is now earning regular plaudits between the sticks for Conference North side Harrogate.
Clubs from the Premier League down to League Two are taking a close look at the impressive youngster.
Newcastle United, Wolves and Doncaster Rovers are among the clubs understood to have checked on his progress in recent weeks.
Harrogate Town youth development officer Garry Plant told Sky Sports that they had not yet received any official offers.
"We have not had a formal approach from any club," Plant told Sky Sports.
"We have obviously heard about clubs watching him and being interested but we have heard nothing officially."
Plant admitted that he believes Harrogate do have a star of the future in their hands.
"He is very, very good," Plant said. "I think he is the next Joe Hart."
