It has been a long time coming, and when he missed the flight for Leeds training camp in Italy the writing finally seemed on the wall for their marquee player.
McCormack has been through it at Elland Road in recent months. He infamously pledged his allegiance to the club on Transfer Deadline day in January - despite interest from Cardiff City, West Ham and co. He said he was happy under Brian McDermott and believed in the clubs future - despite the imminent takeover from the controversial Italian Massimo Cellino.
Then McDermott was sacked just hours later - in quite dramatic style.
McDermott was eventually replaced but he was never going to stick around for long. With his departure at the end of the season McCormack looked destined to go.
And now he has joined Fulham - for a whopping £11 million.
That makes him the most expensive Scotsman of all time, eclipsing the £9 million Sunderland paid Hearts for Craig Gordon.
The fan reaction is certainly mixed.
Many have sympathised with McCormack over the past six months or so. The circumstances have not been easy and they can understand his desire to move. With Fulham only recently coming down and having a manager like Felix Magath in charge they can appreciate his desire to switch to Craven Cottage. Magath, who has won the Bundesliga on three occasions or Dave Hockaday - who battled relegation with Forest Green Rovers on two occasions in the Conference Premier. It is not a difficult choice.
But other fans are less sympathetic. The fact is McCormack had a contract with the club and still forced a move in less than ceremonious fashion. Once you kiss the badge, you better honour it - and many a Leeds fan may never forgive him for that.
But one thing that appears to be unanimous across the board is that Cellino has done fantastic business to get £11 million for the player. His 29 goals will certainly be missed, but that pile of money will definitely compensate for his loss.
Here is a selection of fan reaction to McCormack's transfer...
