Last January, Adams was busy in the winter window, bringing in the likes of Ivan Sproule and Evangelos Ikonomou, and his side duly embarked on an 11-match unbeaten run with eight victories and three draws.
MacGregor told the Ross-shire Journal: "I think we could be quite active in January again, but that is down to the manager.
"Derek has quite rightly put out the message to the players that, unless they actually step up, he is going to have to take in more players in January.
"It is up to them to prove to him between now and January that we don't need to take players in.
"The budget is there to take in new players if needs be and Derek knows what to do. He has proven adept at that in the past and that's why I'm not particularly concerned.
"Yes, I'd like results to be better but we're not particularly worried.
"Our crowds, impressively, have held up. You look at some of the other clubs in the top division and their crowds have really been affected.
"We still have that bounce factor whereby, even though we haven't performed as well as we might, people haven't deserted us.
"But if we haven't got to where we want to be by Christmas, those fans would need to see that we are serious about putting it right in the New Year.
"Everyone is working very hard towards finding that consistency and we need to particularly win our games against teams around about us in the league.
"I do think, overall, we have more quality in the team this year. Technically we are better, so I'm confident we will put it right.
"But you can be assured we are working hard behind the scenes towards putting it right and we will have to sort some of that in January."
