Mac Scorpio is a fictional character from General Hospital, an American soap opera on the ABC network.

[6] York crossed over to All My Children on October 8, 2001, when Mac learned his former sister-in-law Anna Devane (Finola Hughes) was alive.

The character was introduced as a plot device by Monty to delve into Robert Scorpio's (Tristan Rogers) background.

[3] Mac arrived in Port Charles on Valentine's Day in 1991, on a ship owned by the Quartermaines, called the S.S. Tracy.

The ship was having trouble docking into the Port Charles harbor due to engine problems as well as protesters causing a scene.

When Robert was critically wounded after someone threw a plastic explosive into his office, Mac was labeled the prime suspect.

The trio hid out in a mansion in Finger Lakes from the local sheriff who didn't believe Robert and Mac's story regarding the death of Rory.

While in hiding, Dom refused to make love with Mac due to flashbacks of the abuse she suffered at the hands of her husband.

Their wedding was ruined when Ryan escaped from the mental hospital and assumed his twin brother Kevin's identity.

Mac found Maxie's father Frisco in Africa and convinced him to return to PC in case his daughter died.

When Mac threw Robin a surprise party, the guests presented Stone with the memory book she had initiated.

Felicia took on a case of a woman named Tess who hired her to find her missing husband, who left her years ago.

Felicia shared the whole story involving Tess, James, and the fake engagement with the congregation before exchanging vows from the heart with Mac.

Felicia began writing Lila Quartermaine's memoirs and enlisted Luke Spencer, who was grieving over his son's death, to help her.

Mac took another blow when Felicia went back on her promise to stay away from Luke and left town to help him find his son.

As the case developed several twists and turns, Mac asked Felicia to help him figure out the identity of the murderer.

To everyone's dismay, Mac wasn't able to find any physical evidence of Helena's latest evil actions, including bringing Stavros back to life.

When Helena doubled over in pain in her cell during a visit from Luke, Mac tried to convince him she really was sick and was scheduled for surgery.

Mac even allowed Luke to accompany Helena to the prison van to make sure she didn't escape again.

Mac tried to look out for Felicia by warning her against a relationship with Roy DiLucca, who had recently made moves towards becoming a mobster.

When Rick Webber, Laura's stepfather, turned up dead due to a drunk-driving crash, Mac and Scott knew right away it was a set up.

Although they believed Lucky and Nikolas were responsible for moving the body, they thought Luke had actually killed Rick in the attic.

Mac tried to help solve the case by re-enacting the events of that evening to get Brenda to remember more and to disprove Jax's recent confession.

Felicia later persuaded Mac to give her the location of the witness Scott had found who stated she had seen Brenda kill Alcazar.

When Felicia went to Texas to take care of her ailing grandmother Maria, Mac became the primary parent in Maxie and Georgie's lives.

When Maxie went to a party and slept with Kyle, one of the popular guys at school, she didn't realize their encounter was being broadcast over the Internet.

Mac found out about it when he was investigating a tip about a porn site featuring PC high school kids.

Maxie managed to get Zander to the basement of the PC Hotel and promised to get the cash he needed to flee the country.

When Georgie was finally rescued from the fire and arrived at the hospital, Maxie tearfully informed her of Mac's condition.

In the summer of 2008, York appeared on the spin-off General Hospital: Night Shift, when Mac's brother Robert Scorpio was battling colon cancer.
