From the desert to the coast: macOS Mojave has given way to the next major version of the Mac operating system, called macOS Catalina.Revealed during Apple's 2019 WWDC keynote in June, Catalina. There are few great emulator options for OS X, but that is set to change in the near future as multi-source system emulator OpenEmu prepares for an official launch. Open Emu is an open source. Mojave will require at least a Late 2012 iMac or Mac mini, or a Mid 2012 MacBook Air or MacBook Pro. It also of course runs on any new 2017 iMac Pro or new Retina MacBooks (released in 2015),. OpenEmu is about to change the world of video game emulation. For the first time, the 'it just works' philosophy now extends to open source video game emulation on the Mac. With OpenEmu, it is easy to add, browse, organize and with a compatible gamepad. Running OpenEmu v. 1.0.4 on OS X Yosemite v. 10.10.3 with Chrome v. Occasionally OpenEmu will not register any keyboard input, not even to change the button layout in the preferences. Plugging in a controller is a workaround, but the keyboard doesn't work after unplugging it. Restarting both OpenEmu and Chrome solves the problem.
