I just purchased iPad retina mini and it came with 7.0.4 what a surprise?! I wanted to jailbreak this iPad. So, I downloaded evasion 7 and click on app to open in Yosemite on mac mini late 2014 and it can't be opened. I did was going to system preference > security&privacy > clicked lock to make changes and allow to downloaded from anywhere, Problem still here even I restarted still there. Anyone know the fix?
