Hi, Downloaded Blackra1n from Geohot's website and tried to run it on my Macbook. I double clicked the app, but nothing happens. Re-downloaded the file 5 different times and still no luck. The app just doesn't run. Anyone else experience this? The OS on the macbook is clean. I don't have anything other than the usual applications (office, firefox etc.) installed. I eventually ran Blackra1n in Windows on my desktop and the jailbreak completed with no issues. I would like to get Blackra1n to run on my macbook since it runs much faster then my desktop...more convenient since its a tethered jb. Can anyone help? Thanks in advance.
