The TaiG jailbreak group has released a Mac version of their popular jailbreaking utility, allowing OS X users to jailbreak any iPhone, iPad, or iPod touch running iOS 8.4.
Jailbreaking allows users to run unofficial software and tweaks on iOS devices, but is generally only recommended for advanced users who understand the potential issues that may arise with jailbroken iOS devices. Additionally, Apple may void the warranty on such hardware.
The jailbreak is untethered, only requiring a USB cable to complete the initial installation. The process itself is quite simple, with the TaiG tool walking through the entire process of connecting the iPhone, iPad, or iPod touch to the computer, disabling Find My iPhone, installing Cydia and an optional ‘3k Assistant’ package, and finally installing and completing the jailbreak itself. Those interested in using the jailbreak with their iOS device can get the utility from the TAIG website here.

Be aware that Apple may choose not to warranty or support an iPhone, iPad, or iPod touch which is jailbroken, and there are other reasons not to jailbreak iOS as well. Thus, it is strongly recommended that only knowledgable users who understand the process of jailbreaking and unjailbreaking to proceed.
Always back up your iOS device before modifying it’s system software in any way.
The Mac utility follows the earlier release of the Windows version of the TaiG jailbreaking application, which also supports jailbreaking iOS 8.1.3 through iOS 8.4.
