Halion Sonic 2 and Yosamite

I’m moving from PC to Mac. I’ve come to rely somewhat on HS2 s content.
Has anyone had problems with running HS2 on yosamite.
I believe there is a special installer tool needed but I note that there is a disclaimer on Steinberg webpage saying they cannot be responsible for any problems through using this tool.
Will there be come a time when HS2 can be installed without this tool, I wonder.
