The Artemis Macaulay Cup final in Oban could be the beginning of a fairytale first season back in the dug-out for the former player.
MacKintosh must know a little of what his fellow Scot David Moyes must have felt when succeeding Sir Alex Ferguson at Old Trafford. No matter what comforting words are offered, all eyes look to see if the empire will crumble.
When MacKintosh succeeded Norman MacArthur, he knew he was following a legendary figure: the man who returned both the Premiership and the Camanachd Cup to the club and the community. Nevertheless, as he stands on the threshold of a possible first success, he insisted he wasn't losing sleep over the task at hand.
"If I thought at the start that I wouldn't be able to live up to the expectations, I wouldn't have taken the job," he said. "I am quite a confident person plus I knew the team only needed freshening and geed up a bit. That's the way it's been. From day one, the players have been great.
"I wasn't sure how it would all be at the start but I love the training and the Saturdays can't come quick enough. I really enjoy trying to do my best for the boys and the village."
Newtonmore and Kyles have not faced each other in the Premiership this season and now have two major finals in quick succession to sharpen the lances. After today's showcase at Mossfield Park, the pair will do it all again in the Camanachd Cup final at An Aird in September.
"We never look beyond the task at hand," says MacKintosh. "There is so little difference between the top sides that, if you got distracted at all, you will pay for it. We've maybe not played each other this season but we know all about one another."
Newtonmore will be without Rory Kennedy, who had his injured hand pinned at hospital this week and will play no further part this season. Kyles are at full strength and coach James Perlich hopes his side start with some momentum.
"One of the things that has been a problem for us is that we tend to take a while to get going. We can't afford to do that this time."
