LogiTech Mouse-G502

My Logitech G502 mouse can not be found in the Macbook pro Bluetooth list. I had been tried every method on the Internet. Unfortunately, none of it works. By the way, the Bluetooth first-time connection

experience on the new version of the Ipad and Mac is extremely wired and terrible bad. The feeling is worst than connecting the device to Windows. Ultimately, please have someone(technologist, Apple, Logitech, or anyone) help me with solving the problem because I don't want to continue using the Apple magic mouse!
