So you decided to jailbreak your iOS device using Eavsi0n tool on your Mac. You downloaded evasi0n tool and when opened it “evasi0n 7″ can’t be opened because it is from an unidentified developer.
This is something that can be easily fixed and this error pops up because your Mac security settings only allow downloads from Mac App Store and identified developers. Since evasi0n isn’t identified by Apple, here’s how to change security settings.
Step 1: Click on the Apple icon at the left top corner and go to System Preferences.
Step 2: Go to Security & Privacy.
Step 3: Under Allow apps downloaded from area, check ‘Anywhere’ and confirm the warning message.
That’s it. You can now run Eavsi0n on your Mac to jailbreak your device.<
