Problem lunching Unity3d on MacOS????

Hello guys,

I installed Unity3d on MacOs with Yosemite 10.10.4 version

when I lunch it I get this error message: Could not initialize Home Screen Window

help please how to fix it

Did you swap out harddrives? Say an HD for SSD? Unity will give an odd message but I don’t think it’s that one. Maybe you changed CPUs or GPUs?
