I have no idea why ⌘-dragging was not provided for the latter by the system.

One good thing about the former is that you can rearrange them by ⌘-dragging the menu items. The latter can be displayed by any app written by any developer.

The former are loaded and displayed by SystemUIServer, a process provided by the system. There are in fact two types of such menu bar items, one known as NSMenuExtra's and another known as NSStatusItem's. Some features require Apple’s MobileMe service (subscription fees may apply).As you very well know and is shown in the screenshot above, there can be various utilities put on the right hand side of the menu bar.Some features require a compatible Internet service provider (subscription fees may apply).Mac Computer equipped with an Intel processor.Mac OS X 10.6.6 or later installable from the Mac App Store (10.6.8 is recommended).An Intel Core 2 Duo, Core i3, Core i5, Core i7, or Xeon processor.To use Lion, make sure your computer is equipped with the following: They will need 2GB of RAM (we of course would recommend a minimum of 4GB whenever possible) and 8GB free on the disk. This version of OS X can be installed on Macs capable of running OS X 10.9.

All MacBook Airs, MacBook Pros, Mac minis, and Mac Pros are accepted provided they are from 2010 or later. In short, if your Mac runs Sierra today, then it can handle High Sierra because Apple has not restricted the list of compatible Macs.

You can upgrade to macOS Mojave from OS X Mountain Lion or newer on the following Mac models: In detail, the following Macs are compatible : If you are using Mojave MacOS on your Mac, chances are you can install MacOS Catalina. Here is the list of devices compatible with macOS Big Sur :
