I just noticed this morning that Microsoft Teams activates the discrete GPU on my MacBook Pro. I have a new 2019 MacBook Pro. I have uninstalled and reinstalled Teams. I am running version 1.00.213765, which is the latest version of the software. I don't remember seeing this happen with previous versions of Teams on the Mac. For now, I cannot use Teams if I'm on battery, which is very often during my work week.
Before someone responds and tells me to post this in the Teams category, let me stop you now before you waste my time. THERE IS NO CATEGORY OR TOPIC THAT FITS SO THIS IS WHERE I'M POSTING MY ISSUE.
