Some of the blame on that has to land on MS. Teams code just seems to be horribly bloated. Who knows when they will come out with an Apple Silicon native version - but even on my work PC it is pretty laggy. The one device it works well on is my iPhone. I really hope MS rewrites Teams from the ground up.I just want a MacBook that doesn't sound like a jet engine every time I launch MS Teams (while having 15 other apps going as well...but still).
