Keyboard mouse sharing

I am using two computers, but in Windows+Windows, I used it as a Microsoft Garage Mouse with Borders, but this time I used it as a Mac+Windows, so I was worried because the program was not supported.

Once in a hurry, KM switches in Amazon

Delivery is so slow ㅠㅠ… . After all, search for a sharing program

Synergy feels like something is slow
After all, purchase Share Mouse

Final) In Windows+Windows, Microsoft Garage Mouse with Borders
