TransGaming Technologies has developed a product called Cider which is a popular method among publishers to port games to Mac. Cider's engine enables publishers and developers to target Mac OS X. It shares much of the same core technology as TransGaming's Linux Portability Engine, Cedega. Public reception of games ported with Cider is mixed, due to inconsistency of performance between titles; because of this, "Ciderized" games are neither seen as the work of cross-platform development, nor as native, optimized ports. Both Cider and Cedega are based on Wine. Electronic Arts announced their return to the Mac, publishing various titles simultaneously on both Windows and Mac, using Cider.
