WingNuts 2 for Mac

From Freeverse:

WingNuts 2 takes you on a fantastic journey to over 30 real, (and not so real), locations and time periods as you hunt Baron Von Schtopwatch and the mysterious "Raina".

Play through time as you encounter enemies from the 1920s into the distant future. With over 100 real world aircraft, helicopters, blimps, tanks, ships and submarines, you'll never run out of things to shoot!

WingNuts 2 features dozens of "Boss" planes and ground units, a plethora of power-ups, (including Super Mecha Mode), and a Flying Aircraft Carrier as your base of operations. The game sets a new standard for arcade action!
