Full screen mode on the Mac defaults to hiding the menu bar, and while you can swing your cursor to the top of the screen to reveal the menu bar, some Mac users may prefer to have the menu bar always visible when in full screen mode.
Some Mac users may see a “USB Accessories Disabled” error message when using their computer. This is often encountered with a USB-C hub that has many devices attached to it, but it can also occur when a Mac has connected an external USB drive, disk, camera, keyboard, controller, USB-C power cable, or other device to the computer, and then the USB devices are no longer usable or accessible.
