Just loaded Zwift,app on my 2017 MacBook Air (had to type in the password, since the recent update doesn’t store credentials or allow copy and paste) and my fans are already at full speed with almost as much noise as a magnetic trainer. Literally doing nothing in Zwift (I’m typing this message).
Fan 0 speed: 6497 RPM ▁▂▃▅▆▇
And it will be like this for the duration of my session…
Not used many apps that got worse from one week to the next. I’d revert to the prior version if I could find the installer.
