Seasonpass quits unexpectedly-ATV2

Using a MacBook with OS 10.6.8
Downloaded latest iTunes and other software
Jail breaking was no problem…
When I try and do the tethered boot using season pass it recognizes the device in DFU mode then season pass crashes and says “season pass quit unexpectedly”
I have tried this numerous times with no luck. Very frustrated.
I do not have a windows computer so that option is no good. I need to boot it from the above mentioned laptop.
Please help.
Thanks
