Guy Serle

Guy Serle

Podcaster at

Guy is one half of the world famous in his own mind MyMac Podcast along with the equally famous Gary “GazMaz” Malpas. He enjoys beaches, long walks in the park, wet puppy kisses, and occasionally mispronouncing names, products, and national holidays. Sometimes even by accident.

He’s been doing the MyMac Podcast since 2005 in various roles and teamed up with GazMaz (who should have known better) in 2009, when through a serious breach of wisdom was handed the keys to the podcast. In hindsight, people should have known better. He also apologizes for taking his shirt off last year.
