Injury and the arrival of Robbie Fowler and Jimmy Floyd Hasselbaink limited his appearances at Ninian Park and when he did get a chance in the first team he failed to grasp the nettle.
MacLean scored just one competetive goal for City in the 2 - 0 win at Q.P.R back in August.
He was signed by Dave Jones on a free last summer so it's a cute piece of business.
MacLean could be cleared to play for Plymouth on Saturday if the clearance goes through in time.
We wish him well at his new club.
