MacDonald has still to decide whether he wants to take over the reins at the club on a full-time basis.
MacDonald: "I still haven't particularly thought about it. I still haven't any feelings.
"I keep saying that I'll know if I want it. At the moment I haven't got that, although I haven't had time to sit down and think about it.
"It has been a bit of a whirlwind, so I'll wait and see, but I just need to know it's going to be right for myself.
"If I feel I would like to be considered along with others, I will let him (Lerner) know in the very near future.
"It's not just about me, it's about my family. Becoming a Premier League manager is a life-changing thing," added MacDonald.
"It must be a fantastic thing to do, but sometimes people might not really want it. I've not come to that decision or had that thought yet.
"But it is upheaval for families because you never get to see them, you have to chase around, organise things, take phone calls and all that sort of thing, and that's another thing I have to look at.
"But whatever I decide I know they will give me their backing. That is what families do."
At least MacDonald has had the opportunity over the past few days to appreciate the demands and the commitments that come with living life in what must feel like a goldfish bowl at times.
The next three matches, and it is more than likely he will be given those games given their close proximity, may well determine whether he wants to give it a go.
"To actually think about whether I could cope or not, again I've not thought about it," said MacDonald.
"I've coped with a lot of things in my life, but it's not the case for me as to whether I could cope with the job, it's whether I'd like to try and do the job.
"You probably need three or four games, high intensity, high pressure, just to see if it's the be all and end all.
"The one thing I will say is that I've enjoyed being the coach and working on the training ground with the first team.
"From the reserves, I'm now working with the multi-million pound players, but then I never felt it would be a problem doing that because it's one of the things I enjoy doing.
"Some people will say I do it well, some will say not so well - I guess that depends on whether I'm shouting at them.
"But the coaching is the easy thing for me to do. Some of the other things I've not actually had my eyes open to them as yet because we have had to concentrate on the football side."
