The actress has played one of the three main characters of the CW reboot since it began. Season 3 of the series is set to wrap up on July 23, which will mark Mantock’s last appearance as a series regular. Melonie Diaz and Sarah Jeffery remain with the series. Rupert Evans, Poppy Drayton and Jordan Donica also star.
“Playing Macy on ‘Charmed’ for the last three seasons has been an immense privilege and I have so enjoyed working with our fantastic producers, creatives, cast and crew,” Mantock said in a statement. “I’m incredibly grateful to The CW and CBS Studios for my time on the show and for being a brilliant support in my difficult decision to leave. Huge thanks to our fans who can look forward to, what I know will be, a spectacular fourth season.”
