The goalkeeper has only been at Easter Road since January but has seen a determination in the side to push the boundaries at the club he joined from Arsenal.
Despite saving Glenn Middleton’s second-half penalty Macey received a runners-up medal at Hampden after Shaun Rooney’s header beat him in the first half to win the Cup for St Johnstone.
His double penalty save – first palming Middleton’s spot-kick aside with an excellent one-handed save and then kicking away Chris Kane’s follow-up – lifted a Hibs side who were beginning to flag in the second half, but they couldn’t find the equaliser.
"After a moment like that there is going to be a reaction because it was an opportunity for them to really put the game to bed,” he said. “For me, I think we had a reaction from halftime and even after they scored we got on the ball and relaxed and kept playing and didn't panic too much. I think the reaction was always good.”
Now, after inspiring one, Macey believes everyone will see another reaction next season to build on what has otherwise been a positive season for the club – despite falling on the final stage.
"It has been [a brilliant season],” he told BBC Sportscene. “It will take some time to understand and appreciate from everyone. A lot of the players in the dressing room, everyone is ambitious and know their level. It's very clear that they are not prepared to settle for what may have happened in the past.
“The manager, the staff and players have been hugely ambitious in what we want to do and we know our place and how good we can be so there will no doubt be a reaction next season.
"That's the bit that stings because we know how good we can be.
"Since I came in January it's been incredible and we have kicked on and been great in big games but just not to get there at the last little bit is pretty heartbreaking.”
