These are instructions on how to jailbreak the iPhone 6s Plus, 6s, 6 Plus, 6, 5s, 5c, 5, 4s on iOS 9.0 - 9.0.2 using Pangu9 for Mac...
If you aren't already at iOS 9.0.2 we suggest upgrading to the firmware using iTunes. You can find download links for iOS 9.0.2 here. Please note that you must update using iTunes rather than Software Update. If you used Software Update you should do a backup then restore to iOS 9.0.2 using iTunes.
Download the latest version of Pangu for Mac. Double click to mount the dmg file, then drag the application icon into your Applications folder.
Tap Settings from your Springboard then select Touch ID & Passcode. Turn Passcode Off if it is enabled.
Press the Settings button at the top left to return to the Settings menu. Choose iCloudfrom the Settings menu then select Find My iPhone from the iCloud menu. Ensure the Find My iPhone switch is the Off position.
Return to the Settings menu by tapping the iCloud then Settings buttons at the top left of the screen. Then enable Airplane Mode by tapping the Airplane Mode switch.
Connect your iPhone to the computer via a USB cable, launch iTunes, and perform a manual backup. It is very important that you remember to backup your device before continuing as you could lose your data if the jailbreak process does not complete successfully.

You will be prompted to confirm that you've backed up your device and that it's in Airplane Mode, click the Already Backup button (the one on the right) to continue.
The Pangu app will now begin the jailbreak process.
Your device will reboot and at the 65% mark, you will be asked to renable Airplane Mode.
At the 75% mark, launch the Pangu app from the SpringBoard then tap Accept. When prompted tap OK to allow Pangu access to your photos.
Once the jailbreak has completed successfully, your iPhone will reboot and a Cydia app will appear on your SpringBoard.
