I have the client downloaded, but when I open it i just get a brief windowed black screen, and then it just closes. :/
ok so i reinstalled it with chrome and turned off the malware protection, but the same problem is present.
What version of OS X are you running? It sounds like there is some client sided issue but I don't know what exactly.
Hold alt and click the app, then click advanced. Make sure windows EXE is set to "/Nexon/MapleStory/MapleRoyals.exe"
