To be brief I am running one of the old macbooks. I am trying to jailbreak with the redjolt semi tethered method and have run into issues before I really get the process started. In part of that tutorial it says you must have a "pwned 2.2.1 IPSW" or custom 2.2.1 IPSW. I downloaded the newest version of the pwnage tool for mac. 2.2.5 and I downloaded the related IPSWs and from firefox. I've tried ones that download as ipsw and also as a zipped file. When I put them through the pwnage app everytime it says wrong firmware bundle. What am I doing wrong or is there some issues in the actual pwnage tool?
