Do Mac app devs really do much to reduce power consumption? It doesn't seem like anything special to me, but I haven't actually shipped anything Mac-specific in a long time. Most of the power on a given day will go to web apps anyway, which ofc the dev doesn't optimize for Mac, and it seems like the Macs do that more efficiently too.
