Help with jailbreak ATV2

I am using a Apple TV 2 with updated iOS 6.2 I believe, iTunes version 10.7
and using a Mac with iOS 10.7 Lion. Download seasOnpass, create IPSW and
Get an error message that reads : process failed with reason: file system patch failed!

Help? Tried to uninstall and reinstall and update and "down"date
And cannot figure it out?

Figured it out, it was my Mac operating system
Upgraded from lion 10.7 to maverick 10.9
Took a whole 4 minutes from start to finish
