You can use the bottom panel as a guide or the screenshot above if you’re not sure which widgets to place. Do the same with the clock widget and add anything you want really. Select the system tray from the Widgets and drag it to the very right of the top panel to place it.Right-click anywhere and select Add widgets. When you have the desired height, you can start adding widgets.Click on the hamburger menu icon (three horizontal lines) on the very right and drag the Height button up or down to increase or decrease the height of the top panel to your liking.The panel you see in screenshots is the finished product and sadly I’m not willing to undo it all so … This will add a white bar at the top of your screen. Right-click anywhere on the desktop and select Add panel > Application menu bar.Before we can change anything, make sure widgets are unlocked. In the screenshot above you can see the default KDE panel at the bottom, and a customized panel at the top that looks like the menu bar on a Mac. Yet, it’s KDE Plasma that can replicate MacOS’s menu bar the best, as far as I know. Some other desktop environments give more of a Mac feel with a top panel that houses the time/date, system tray, etc. KDE Plasma looks more like Windows, by default than Mac.
