MacOS 10.10+, Linux, and Windows 7+ are supported. Thanks to Reddit user /u/IrisFlame for the premade library of crosshairs! CrossOver offers a huge improvement to many games' default crosshairs for those with colorblindness or contrast issues. CrossOver is a small, unintrusive crosshair overlay which has plenty of configuration options to assist with aiming and vision of your crosshair. Other crosshair programs offer a single style or color option, and often don't allow you to reposition them.
