Add and Rearrange Menu Bar Toggles
The macOS menu bar is a handy way to quickly access various native features and third-party apps from basically anywhere in macOS. But, by default, the menu bar is pretty sparse. Luckily, you can change that pretty easily.
For one, click on the battery icon and select Show Percentage.
Want a volume indicator in the menu bar? Go to System Preferences > Sound and check the box next to Show volume in menu bar. You can do the same for Bluetooth.
Also, if you aren’t happy with how the menu bar icons are arranged, you can change that, too. Just hold down Command and drag the menu bar icons into whichever order you’d like.
