I2 won't open on Mac

[Toeknee]

Diablo will not open on my Mac, icon will appear on bottom right jump around for a bit and vanish. Don't know if this is normal or not. When I try to make changes on the tune some things will fail like disabling traction or disabling MDS. Any help would b greatly appreciated

Note the fix in the other thread you posted in, update the Java version on the Mac and try again.
