Under Sierra, we have much greater freedom to configure what’s called the Menu Bar; that’s the bar that appears at the top of your screen, containing both system icons (like the clock and Wi-Fi) and icons for third-party programs (in my case, like 1Password, Dropbox, and Cloak).
Before Sierra, we could move some of the system icons, but not the third-party ones. Now, nothing’s off limits except Notification Center (the three-lined icon), which has to stay pinned to the right.
Customizing your Menu Bar is really simple. Just hold down the Command key on your keyboard, and then click and drag any icon to rearrange things. So here’s an incredibly exciting screenshot of me moving 1Password next to Notification Center:
Weird. That’s weird. I’ve been using OS X/macOS for long enough that having a third-party icon all the way over there is almost…disorienting. But gosh, at least now I have the choice to do so!
