redsn0w on OS X

RedSn0w is always available for both Mac OS X and Windows at the same time, so no usergroup is left in the dark. Yet another advantage to the RedSn0w Jailbreaking tool is that it encompasses so many additional features. Nowadays RedSn0w really is your go-to tool for everything Jailbreaking related. Redsn0w 0.9.15b3 for Mac is available as a free download on our application library. Our built-in antivirus scanned this Mac download and rated it as virus free. This free software for Mac OS X was originally designed by iPhone Dev Team. The program lies within System Tools, more precisely Plugins & Addons.

Version 0.9.10b1 adds support for iOS 4.2.6 through 5.0.1 (though iOS 4.2.9, 4.2.10, 4.3.4, 4.3.5, and 5.0 are tethered on devices invulnerable to the 0x24000 Segment Overflow). This build of redsn0w is not capable of jailbreaking S5L8940 or newer devices.
