Seas0npass 0.9.5 using Yosemite Beta not working

I’ve tried to jailbreak my ATV2 using the latest Seas0npass 0.9.5 under Mac OS X 10.10 Yosemite (Beta 5).
The ATV is detected but the IPSW download show no progress at all … get’s stucked.

Anyone having this issue?

With me the jailbreak does not work with Yosemite 10.10 (no Beta). No solution?
