I'm trying to determine the battery health on an old MacBook Pro. Specs are: A1398 MacBook Pro (Retina, 15-inch, Mid 2014), Model Identifier MacBookPro11,3, running macOS 11.5.2 (Big Sur).
According to this Apple support page (note that the OS selector is correctly set to Big Sur), I can do that by going to:
Apple menu > System Preferences > [Battery icon] > [Battery icon], at which point I'm supposed to see a button entitled
Battery Health..., and I'm to click that. The image below (from this Tom's Guide article) shows what I should see:
But I don't. I see the following:
As you can see, it is very similar to the previous one, but a major difference is that the
Battery Health... button simply isn't there.
Any ideas why I'm seeing something different from what Apple says I should? And, more to the point, any ideas how I might determine my battery health?
