England youth international MacIver rejoined Everton in January 2020 having initially come through the ranks at the Club.
She made four appearances in the curtailed 2019/20 campaign when the goalkeeper's promise was recognised with her inclusion in England's squad for the SheBelieves Cup in America.
MacIver didn't make a senior appearance for the Blues first time around, instead going on to spend a year with Manchester City before signing up to a scholarship with American university side Clemson Tigers.
Establishing herself as the first-choice stopper during three seasons with Clemson, she returned to the WSL at the conclusion of her scholarship to link up with Willie Kirk's Everton, penning an 18-month deal.
Having represented England at youth levels up to Under-21, MacIver was handed a first senior call up for friendlies against Belgium and Norway in August 2019 but did not feature.
The previous summer she had been part of the young Lionesses squad that finished third at the Under-20 World Cup in France and scooped the Golden Glove as the tournament's best keeper.
Contracted until: June 2021
