The system icons will be separated from the running icons and for each you can choose where it shows up, if it is visible, and whether it will appear when a change is made that affects it. After this is done, however, you can open the Preferences menu and start managing your icons. Installation of Bartender is easy and fast, though the app will need to install a secondary file in the background to run properly. Sitting in the menu bar, itself, Bartender is low profile and uses minimal memory to perform basic functions like hiding icons, moving them into the separate Bartender menu, and setting notifications to show the items only when necessary.
Bartender allows you to control more of the icons at the top of your computer's menu bar, including system icons that are typically off limits, making it a very useful app for those with limited space.
